preparation example Construction

[0036] The preparation method of the acrylate rubber emulsion preferably includes directly polymerizing the acrylate monomer as the main component by emulsification polymerization. The acrylate monomer is, for example, methyl methacrylate, ethyl methacrylate, propyl methacrylate, butyl methacrylate, pentyl methacrylate, hexyl methacrylate, heptyl methacrylate , 2-ethylhexyl methacrylate, methyl acrylate, ethyl acrylate, propyl acrylate, n-butyl acrylate, pentyl acrylate, hexyl acrylate, heptyl acrylate, 2-ethylhexyl acrylate, Lauryl acrylate, etc. or a combination of the above compounds, among which n-butyl acrylate is preferred.

[0037] In addition, the preparation method of the acrylate rubber emulsion may further include adding a bridging agent during the polymerization reaction. Bridging agents such as but not limited to ethylene glycol diacrylate, butylene glycol diacrylate, divinylbenzene, butylene glycol dimethacrylate, dimethacrylate, trimethylol tri(meth)acrylate P...

[0103] 1. Polymerization reaction

[0104] First, 99.5% by weight of n-butyl acrylate, 0.5% by weight of allyl methacrylate, surfactant (Sodium dihexyl sulfosuccinate), manufactured by Cytec (Cytec) SA-80) 3.5 parts by weight, tertiary butyl hydroperoxide (BHP) 0.2 parts by weight, ferrous sulfate solution (FeSO4) 0.02 parts by weight, sodium formaldehyde sulfoxylate solution (SFS) 1.3 parts by weight, ethylene diamine tetraacetic acid Disodium (ethylenediaminetetraacetic acid disodium salt dehydrate, EDTA-2Na) 0.2 parts by weight and distilled water 165 parts by weight, wherein n-butyl acrylate and allyl methacrylate are added to the reaction system for polymerization within 5 hours (added in a continuous manner), In this way, an acrylic rubber emulsion can be obtained. Next, the acrylate rubber emulsion is coagulated with calcium chloride to obtain a solution containing ungrafted first rubber particles. At this time, the weight average particle diameter of the ungrafted fi...

Abstract

A thermoplastic resin component is provided. The thermoplastic resin component comprises polycarbonate (A); a resin mixture (B) comprising acrylate-based rubber; first particles (C); second particles (D); a flame retardant (E) and polytetrafluoroethylene resin (F). The resin mixture (B) comprising the acrylate-based rubber comprises acrylate-based rubber (B1) and styrene-acrylonitrile copolymer (B2). The first particles (C) have an acrylate core portion and a first cover layer covering the acrylate core portion. The second particles (D) have a butadiene core portion and a first cover layer covering the butadiene core portion.

Description

technical field [0001] The present invention relates to a resin composition, and in particular to a thermoplastic resin composition. Background technique [0002] Thermoplastic resins have been widely used in various fields, such as household appliances, mechanical parts, office supplies, electronic components, automobile industry and many other fields. In order to meet the industry's requirements for hardness and other properties, current research is mainly directed towards mixing thermoplastic resins into a composition with specific properties for subsequent application. [0003] In general, plastic molded products used for electrical equipment and household goods contain rubber-modified styrene resin, polycarbonate resin, or methacrylate-based rubber-modified resin. The methacrylate-based rubber-modified resin is a ternary graft copolymer composed of acrylonitrile, styrene and acrylate rubber. Compared with rubber-modified styrene-based resins, methacrylate-based rubber...
