Definitions
- the field of the present invention is that of additives for polymers fulfilling both the function of antacid agents and antistatic agents.
- N, N-bis (hydroxyethyl) -N-alkylamines and preferably the alkyl derivatives in in particular N, N-bis (hydroxyethyl) -N-stearylamine or the corresponding industrial derivatives with tallow chain or hydrogenated tallow.
- N, N-bis (hydroxyethyl) -N-C 16 -C 2 alkylamines are liquid or at least pasty substances and their incorporation in the state poses difficult industrial problems. Already, these are products that are difficult to handle. But taking into account that, for the transformation of plastics, the procedure is mainly carried out by the technique of masterbatches, that is to say that which consists in making a premix of the adjuvants with part of the resinous compounds of the polymer composition, such a premix with liquid adjuvants has an annoying tendency to form sticky agglomerates on the walls of the supply and metering system during the formulation of the final composition, for example on an extruder with twin co-pounding screws.
- antacid and antistatic compositions in the form of flakes which include, in addition to N, N-bis (hydroxyethyl) -N-alkylamine (antistatic agent), antacid agents such as hydrotalcites ( 1 hydrotalcite sensu stricto and synthetic hydrotalcites corresponding to the formula (Mg) a (Al) b (C0 3 ) x (OH) y (H 2 0) z , with 2 ⁇ a ⁇ 6, l ⁇ b ⁇ 3, l ⁇ x ⁇ 5, 8 ⁇ y ⁇ 14, and 0 ⁇ z ⁇ 3) ⁇ zinc oxide or magnesium oxide, solidifying agents such as titanium dioxide, barium sulfate, talc , ethylene bis-stearamide wax, stearates in general, a flaking agent such as calcium stearate.

- the antacid agents recommended according to the invention are hydrotalcites.
- the solid formulations according to the invention have a melting temperature between 40 and 80 ° C, in practice at least 4 ° C. They are made in the form of scales homogeneous, non-sticky or dusty, which are formed by premixing their various ingredients at a temperature of about 80 ° C and passing through the scaler.
- the scaler is a device essentially consisting of a scaly roller in immediate contact with a smaller diameter inking roller which is immersed in a tank where the product to be chipped is kept melted.
- the inker rotates in the opposite direction to the scaler and deposits a thin and uniform layer of the product on it.
- the scaler is kept at a temperature between 15 and 20 ° C below the solidification temperature of the product to be scaled.
- a solidified film is formed there, which is detached by a
- the debris is sent to a grinding-crumbling system, from which the scales then go out towards the conditioning workshop.
- aluminum stearate which has an anti-clumping action , represents from 5 to 15% by weight of the formulation, preferably from 5 to 10% by weight.
- the preferred formulations contain from 5 to 10% by weight of antacid agent.
- the solidifying agent (s) represent from 0 to 10% by weight of the formulation.
- the particularly preferred formulations according to the invention are free of solidifying agents.
- the invention also relates to polymer compositions comprising per 100 parts by weight of polymer components, from 0.1 to 40, preferably 0.1 to 15 parts by weight of the solid formulation according to the invention. Preferably, this formulation is present in an amount of 0.1 to 2.5 parts by weight relative to the weight of the polymer components of the composition.
- the polymer components of said antistatic polymer compositions are olefin polymers and copolymers and their alloys, styrenic polymers and copolymers and their alloys, acrylic and methacrylic polymers and copolymers and their alloys and vinyl polymers and copolymers and their alloys.
- polyolefins such as polyethylenes, polypropylenes, polybutylenes and olefin copolymers such as ethylene-propylene copolymers.
- styrenic polymers and copolymers of the compositions of the invention mention is made of homopolymers of styrene, homopolymers of alkylstyrene such as ⁇ -methylstyrene, and grafted styrenic polymers.
- HIPS high impact resistance polystyrenes
- the styrenic polymers which are particularly recommended for the compositions of the invention are acrylonitrile / butadiene / styrene emulsion resins and / or suspension and / or mass, called ABS resins, synthetic butyl rubbers and their alloys, in particular 7ABS resins containing 4 at 70% by weight of butadiene relative to the total weight of the resin, and the alloys of ABS resins and of styrene / acrylonitrile copolymers called SAN resins.
- ABS resins synthetic butyl rubbers and their alloys, in particular 7ABS resins containing 4 at 70% by weight of butadiene relative to the total weight of the resin, and the alloys of ABS resins and of styrene / acrylonitrile copolymers called SAN resins.
- the resin is in the form of granules, it preferably contains from 4 to 40% by weight of butadiene, better still from 4 to 30%.
- the resin is
- the alloys recommended according to the invention are those which include grafted ABS resins, that is to say comprising S7 ⁇ N grafted onto a polybutadiene substrate.
- the recommended grafted 7ABS resins generally contain 10 to 70% polybutadiene.
- the preferred alloys are those which contain from 10 to 80 parts by weight of a grafted ABS resin and 90 to 20% by weight of S7AN resin, better still 30 parts of grafted ABS and 70 parts of SAN resin.
- compositions may also contain one or more adjuvants chosen from lubricants, internal or external, pigments, dyes, UV stabilizers, antioxidants, flame retardants, anti-scratch and extension and strengthening charges.
- adjuvants chosen from lubricants, internal or external, pigments, dyes, UV stabilizers, antioxidants, flame retardants, anti-scratch and extension and strengthening charges.
- EXAMPLE 1 Antistatic or Antacid Formulations and Their Properties Table I brings together various formulations of antistatic / antacid compositions, as well as some of their physical or applicative characteristics, the mode of assessment of which is explained below.
- the melting peak is that observed by differential scanning calorimetry
- the weight loss results are those provided by the thermogravimetric analysis; they are expressed by the temperature at which a weight loss is recorded, of 1, 2, 3 and 5% respectively;
- a layer of 3 cm of antistatic agent is deposited, then a molded disc 10 cm in diameter in ABS is deposited on this layer and a metallic mass of this is placed above this disc. 700 g.
- the whole is then placed in a ventilated oven at a determined temperature for 4 hours. After cooling for 15 minutes, it is observed whether flakes or grains have adhered to the 7 ⁇ BS disc and if there are agglomerates of flakes. Tests were carried out at four different temperatures of the oven, 35, 40, 45 and 50 ° C. The temperature adopted is that for which no glitter agglomerate has been observed.
- This caking test gives an indication of the aptitude for the formation of agglomerates of the antistatic agent when storing a pallet of bags containing the antistatic agent during the hot period in summer. Consequently, the higher this temperature, the lower the risk of the formation of agglomerates during the manufacture of the masterbatches.
- Table I shows that the additive according to the invention according to the invention (Example 1) offers a compromise in physical property at least equal to that of the formulation of the prior art.
- Polymer compositions have been produced, the composition of which is given in Table II below, by mixing using an internal mixer or a twin screw extruder in a conventional manner.
- the hot melt index is measured according to ISO 1133 at 220 ° C under 10 kg and expressed in grams per 10 minutes;
- the viscosity is measured in mPa.s with a capillary rheometer at 230 ° C, the shear rate being 1000 s "1 .
- the impact resistance is the Izod resistance measured according to ISO 180 / 1A at 23 ° C, and expressed in kJ / m 2 .
- the softening temperature is the temperature
- Vicat B measured according to ISO 306B at 120 ° C, and expressed in degrees centigrade.
- the gloss and haze measurements are carried out on molded plates using a Gardner device according to ISO 2813 method.
- Test pieces were also produced by molding at high temperature and visually observed the appearance or absence of marks on the test pieces. The results are reported in Table III.
