Embodiment 1

[0151] Mix heat-resistant resin emulsion A1 with ABS emulsion B1 and the emulsion of additives at a ratio of 10:55:0.82, and add 100 parts of the mixed emulsion to the temperature of 65°C at 25°C under stirring In the aqueous solution of 300 parts of 5 ‰ of magnesium sulfate, maintain uniform feeding speed and add in 30~35 minutes. After adding the emulsion, raise the temperature of the mixture to 95°C and maintain it for 1 hour before cooling down to complete the coagulation process. The condensed slurry is filtered, washed with desalted water, and then dried to form a mixture of A1 and B1. Mix 65 parts of dried A1 and B1 mixture with 35 parts of C2 and 0.80 parts of blending aid in a high-speed blender. The blend can be passed through a twin-screw extruder to obtain a heat-resistant resin composition product. The performance of the product is shown in Table 2.

Embodiment 2

[0153] Mix the heat-resistant resin emulsion A2 with the emulsion of ABS emulsion B1 and additives at a ratio of 25:50:0.80, and add 100 parts of the mixed emulsion to 100 In the aqueous solution of magnesium sulfate of 2‰, maintain a uniform feeding speed and finish adding within 30 to 35 minutes. After adding the emulsion, raise the temperature of the mixture to 97°C and maintain it for 1 hour before cooling down to complete the coagulation process. The condensed slurry is filtered and washed with desalted water, then dried and set aside. Mix 75 parts of dried A1 and B1 mixture with 25 parts of C1 and 0.80 parts of blending aid in a high-speed blender. The blend can be passed through a twin-screw extruder to obtain a heat-resistant resin composition product. The performance of the product is shown in Table 2.

Embodiment 3

[0155] Mix the heat-resistant resin emulsion A3 with the emulsion of ABS emulsion B1 and additives according to the ratio of 35:40:1.20, and add 100 parts of the mixed emulsion continuously to the 500°C at 70°C under stirring In the aqueous solution of magnesium sulfate of 8‰, maintain a uniform feeding speed and finish adding within 30 to 35 minutes. After adding the emulsion, raise the temperature of the mixture to 100°C and maintain it for 1 hour before cooling down to complete the coagulation process. The condensed slurry is filtered and washed with desalted water, then dried and set aside. Mix 75 parts of dried A3 and B1 mixture with 25 parts of C3 and 0.80 parts of blending aid in a high-speed blender. The blend can be passed through a twin-screw extruder to obtain a heat-resistant resin composition product. The performance of the product is shown in Table 2.

Abstract

The invention provides a maleimide heat-resistant resin composition with improved lustrousness. The heat-resistant resin composition comprises the following raw materials based on 100 mass portions: 10 to 65 portions of maleimide heat-resistant resin, 30 to 55 portions of graft polymer of conjugated diolefine rubber graft aryl vinyl monomer, nitrile grouping vinyl monomer or / and copolymerizable acrylic ester monomer of which copolymerizable acrylic ester monomer accounts for 0 to 10 mass percent, and 5 to 35 portions of biopolymer of aryl ethylene monomer and nitrile vinyl monomer. The heat-resistant composition prepared by a preparation method of the maleimide heat-resistant composition has the advantages of excellent comprehensive performance, attractive appearance, high heat resistance and good lustrousness. The prepared heat-resistant resin can be widely applied in the aspect of heat resistance and modification of ABS, PC, PBT and other materials, can be used as a material with excellent heat-resistant performance, can be independently used, and can be used for preparing high heat-resistant parts of automobiles and household electrical appliances.

Description

technical field [0001] The invention relates to a polymer heat-resistant resin composition with improved gloss and a preparation method, in particular to a maleimide heat-resistant resin composition with improved gloss and a preparation method. Background technique [0002] Free radical copolymers of maleimide monomers have attracted extensive attention because of their molecular chains containing planar five-membered ring structures, which can effectively inhibit chain rotation and thus have high structural rigidity and thermal stability. Among them, there are many studies on the copolymers of maleimide monomers and aryl vinyl monomers. Terpolymer of aryl vinyl monomer (AEM), nitrile vinyl monomer (NEM) and maleimide monomer. [0003] The preparation of ultra-high heat-resistant ABS resin includes alloy method and copolymerization modification method, among which copolymerization modification method is a better technical route. The alloy method mainly refers to the PC / ABS...
