Abstract

The invention discloses MBS resin with impact resistance, stress crease and fold resistance and excellent transparency and belongs to the only high-molecular compound obtained through C-C unsaturated bond reaction. The MBS resin contains fluorine, comprises a repetition structure unit from hexafluoropropylene in the molecular structure and is realized in the following steps: in the seed emulsion preparation steps, styrene and butadiene polymerization monomers as well as hexafluoropropylene polymerization monomers are added to participate in emulsion polymerization reaction. The polyvinyl chloride modifier MBS resin product which can improve the shock strength and the stress crease and fold resistance and is high in light transmittance and excellent in optical performance is provided, so that the shock strength of the MBS resin is remarkably improved, the stress crease and fold resistance is radically improved, the light transmittance is improved, and the MBS particle diameter is increased from 80nm to 240 nm.

Description

technical field [0001] The invention is an MBS resin with good impact resistance, stress whitening resistance and good transparency. It belongs to the polymer compound obtained only by the reaction of carbon-carbon unsaturated bonds. Background technique [0002] Polyvinyl chloride (PVC) is a thermoplastic polymer material developed earlier, with high strength, wear resistance, flame retardancy, electrical insulation, good chemical corrosion resistance, excellent optical properties and low price. Industrial and civilian markets have broad prospects. However, due to the PVC resin itself, there are many defects in plasticizing processing performance, thermal stability, oxidation resistance, impact resistance, bending and folding resistance, etc. As a result, it is limited in practical industrial manufacturing applications. Over the years, PVC resin has been successfully applied in various fields of construction, telecommunications, transportation, chemical industry, packagi...
