Definitions

  • Sandwich elements made of plastic cover layers and a core for the production of mobile, temperature-controlled containers
  • the invention relates to sandwich elements made of plastic cover layers and a core for the production of mobile, temperature-controlled containers, methods for their production and their use.
  • the state of the art for trucks is box bodies made of sheet steel, of a steel-wood composite construction, and for temperature-controlled containers, in particular bodies made of sandwich elements.
  • Such sandwich elements have a cover layer and a core on the outside and inside.
  • the cover layers can consist of metal or plastic materials (DE-A 39 16 065).
  • the sandwich elements used for insulated containers should preferably have a high degree of rigidity with a low weight. They must be able to cope with the load from forklift trucks in the floor area, the load from storey loading in the side wall area and the load from hanging loads in the roof area. In order to be able to be used when transporting frozen products, for example, they must ensure that the low transport temperature is maintained at high outside temperatures.
  • plastic sandwich elements with a length of up to approximately 16,000 mm in various widths and thicknesses are known.
  • the core of each of these elements is partially or completely enclosed by plastic cover layers.
  • These sandwich elements are self-supporting and achieve a high payload for the entire vehicle due to their low weight. Depending on the dimensions of the container, they are manufactured in customized shapes.
  • a surface fleece is placed on top of the surface fleece, several glass fiber and opaque fabric mats, usually as a combination mat. After each layer, resin must be applied manually with the tundish. A complex extraction system must ensure that the MAK values are adhered to. Then the foam sheets cut to fit the vehicle, including wood or metal reinforcements, are inserted.
  • Fabric mats are placed between the individual foam sheets to reinforce the wall. Each of these mats must also be soaked in resin by hand.
  • the inserted foam sheets are covered with resin from the tundish. Glass fiber and fabric mats are put on again as a top layer (combination mat). The completely filled form is poured over again with resin and a deck vie is applied. After a final pouring of resin, the mold is closed with the gel-coated lid.
  • the closed mold is inserted into a hot plate press and the resin is cured under pressure (approx. 1 bar) and temperature (approx. 60 ° C).
  • This method is very complex and also has other disadvantages. On the one hand, a high shrinkage can be observed when curing. This creates a rough surface. The liquid resin consumption is very high, since an excess of liquid resin of about 15% must be added to ensure process reliability. This production releases styrene. The MAK values must be checked and adhered to. Another crucial disadvantage is the lack of automation potential with a high value chain.
  • the object of the present invention was therefore to provide sandwich elements which can be produced by a simple method and which do not have the disadvantages of the sandwich elements known from the prior art.
  • the special feature of the sandwich elements according to the invention is that low-pressure SMC is used instead of the cover layers previously produced in situ in such cases and the reinforcements made of glass fiber reinforced plastic (GRP).
  • GRP glass fiber reinforced plastic
  • SMC stands for "Sheet Molding Compound” and is the English name for a resin mat according to DIN 16913.
  • SMC is generally used to refer to a flowable resin mat with isotropic properties and random fiber distribution in the mat plane.
  • SMC is a flat semi-finished product based on unsaturated polyester resin and / or vinyl ester resin. Glass fibers are usually used as reinforcement fibers, but other materials are also suitable for reinforcement.
  • a typical SMC recipe consists of approx. 30% polymer, approx. 30% filler and approx. 30% fibers, the rest is made up of additives, such as color pigments, hardeners, dispersing agents and similar substances.
  • SMC is made from a resin base paste and reinforcing fibers. The resin base paste is applied to two carrier foils.
  • carrier foils are drawn through the SMC machine and thereby transport the resin paste onto which the reinforcing fibers are sprinkled or placed. After the reinforcing fibers have been applied, both foils are pressed together so that a kind of sandwich is created. This sandwich is pulled through an impregnation line, which uses pressure and flexing movements to ensure that the fibers are evenly wetted with the resin base paste. At the end of the machine, the semi-finished product is wound on rolls. A ripening process that can be initiated in a chemical and / or physical manner is of crucial importance. After this maturation process, the SMC can be processed further.
  • the SMC is usually processed into molded parts in heated steel tools.
  • the mold temperature is generally about 135 to 155 ° C.
  • the decomposition of the hardener is started by the mold temperature and the molding compound undergoes an exothermic crosslinking reaction.
  • the material When processing in press tools, the material is usually dosed manually. Maintaining precise dosing quantities is generally very important for problem-free production.
  • the SMC is usually prepared and weighed according to a cutting plan. Weighing out the blank serves as a control and enables a possible correction of the blank. Then the SMC is placed on the tool and the tool is closed. The pressure is built up and held until the molded part is completely hardened.
  • the SMC according to the invention contains as a base paste a mixture of at least one unsaturated polyester resin and / or vinyl ester resin as the base component, at least one shrinkage-compensating additive, at least one hardener and additives.
  • the base paste preferably contains at least one resin based on maleic acid, isophthalic acid, orthophthalic acid, terephthalic acid, tetrahydrophthalic acid, adipic acid or bisphenol-A, as vinyl ester resin preferably at least one resin based on bisphenol-A or novolac or mixtures of these resins .
  • Saturated polyesters for example, or products based on polyurethane, polyvinyl acetate, polymethyl methacrylate, polystyrene or styrene-butadiene or mixtures of these additives are admixed with this base component as a shrinkage-compensating additive.
  • Suitable components are known per se to the person skilled in the art and are commercially available for semi-finished SMC products.
  • Organic peroxides that start at the lowest possible temperatures are used as hardeners. Examples include t-butyl per-2-ethylhexanoate, bis- (4-t-butylcyclohexyl) peroxydicarbonate, benzoyl peroxide and methyl isobutyl ketone peroxide. Mixtures of these peroxides, which are known per se in SMC technology, can also be used.
  • this resin base paste also contains the usual additives known to those skilled in the art, such as additives to ensure storage stability, additives for deaeration, thixotropic agents, thickening aids, fillers and pigments, and, depending on the application, adhesives and / or release agents.
  • additives include, for example, the known components which stabilize peroxide-containing UP resin batches, the known foam-inhibiting polymers, silicas such as, for example, aerosils, calcium carbonate, aluminum trihydrate, kaolin and barium sulfate.
