Described nonionic emulsifying agent is selected from Witconol AL 69-66, anhydrous sorbitol tristearate (this dish 65), glycol fatty acid ester, propylene glycol fatty acid ester, anhydrous sorbitol list hard fatty acid ester (this dish 60), sorbitan monooleate (span 80), Diethylene Glycol fatty acid ester, anhydrous sorbitol monopalmitate (this dish 40), polyoxytrimethylene hard fatty acid ester, sorbitan mono-laurate (this dish 20), polyoxyethylene hard fatty acid ester, lauric acid polyoxyethylene ester, polyoxyethylene (4) anhydrous sorbitol list hard fatty acid ester (Tween61), polyoxyethylene (5) sorbitan monooleate (sorbimacrogol oleate100), polyoxyethylene (20) anhydrous sorbitol tristearate (polysorbate65), polyoxyethylene (20) Witconol AL 69-66 (polysorbate85), polyoxyethylene monoleate, fatty alcohol amine polyoxyethylene ether, alkylphenol polyoxyethylene, polyoxyethylene mono-laurate, polyoxyethylene castor oil, polyoxyethylene (4) sorbitan mono-laurate (tween 21), polyoxyethylene (20) anhydrous sorbitol list hard fatty acid ester (polysorbate60), polyoxyethylene (20) sorbitan monooleate (tween 80), polyoxyethylene (20) anhydrous sorbitol monopalmitate (polysorbate40), at least one in polyoxyethylene (20) sorbitan mono-laurate (polysorbas20),
Described anionic emulsifier is selected from least one in dialkyl group-2-sodium sulfosuccinate, dicyclohexyl-2-sodium sulfosuccinate, succinic acid sodium sulfonate, sodium oleate, potassium oleate, Emulphor FM;
Said molecular weight regulator is at least one in positive Dodecyl Mercaptan or tert-dodecyl mercaptan.
Said initiator is selected from least one in Potassium Persulphate, Sodium Persulfate, ammonium persulphate.
Said alkaline matter is selected from alkali-metal oxyhydroxide, preferred sodium hydroxide, and preferably adopting weight content is 10%～40% aqueous sodium hydroxide solution;
Modified butadiene-styrene latex of the present invention, can be for building coating binding agent.
Common emulsifying agent is after emulsion film forming, compatible with polymer body because being difficult to, and easily moves to the surperficial of film or the interface that is connected with base material and make the water tolerance variation of film, and and base material between sticking power variation.And the present invention adopts compound emulsifying agent, this emulsifying agent can be with the formal bond of chemical bond with on polymer chain, therefore can not migrate to the surface of film or the interface that is connected with base material on and water tolerance that can reinforcing membrane, improve and base material between sticking power.In addition, conventionally in styrene-butadiene emulsion, add wilkinite can reduce the cohesiveness of emulsion.But contriver studies discovery, add in the present invention hydrogen base bentonite not only can not reduce the cohesiveness of styrene-butadiene latex, also can increase on the contrary, produced unexpected effect.
Modified butadiene-styrene latex of the present invention is a kind of product that can meet building coating high-performance, environmental protection for binding agent.This product is used in building coating, can obviously improve the water tolerance of paint coatings and the sticking power between base material, and improves the cohesiveness of latex.
