Abstract

This invention provides the method for preparating a kind of high impacting and high heat-proofing blending ABS resin. By extruding heat-proofing ABS gained by emulsion polymerization and current ABS resin gained by bulk polymerization, we can prepare high impacting and high heat-proofing. Current ABS resin, whose rubber particle size is 1-10ª–m, possesses low impact strength, middle impact strength and high impact strength. In heat-proofing ABS resin, the rubber whose particle size is in the range of 0. 1-2ª–m occupies 50% of total rubber particle volume. Because of the appropriate proportion of the two resins and reasonable distribution of the rubber particle size, The produced blending ABS resin has both high impacting and high heat-proofing proeries, and its impact strength could attained to 17. 8-32. 6KJ / m2, and softening temperature could attained to 104-110deg C. Blending ABS resin is easy to make, costs little, so it is feasible to commercial manufacture.

Description

technical field [0001] The present invention relates to a preparation method of a blended ABS resin, in particular to a method for preparing a high-impact and high-heat-resistant blended ABS resin by blending and extruding a general-purpose ABS resin obtained by bulk polymerization and a heat-resistant ABS resin obtained by emulsion polymerization method. Background technique [0002] ABS resin has good impact strength, high hardness and chemical resistance, but generally not high heat resistance. ABS resin application fields such as automobiles and motorcycles require materials to have excellent heat resistance in addition to the above properties. In order to meet the needs of the material application field, people try to prepare heat-resistant ABS resin through various methods, such as preparing ABS resin by adding heat-resistant modified monomers in the emulsion polymerization process, adding heat-resistant modified monomers in the bulk polymerization process, etc. Synt...
