preparation example Construction

[0026] The preparation method of a kind of impact-resistant stretch-resistant plastic, it comprises the following steps:

[0027] a) Take PVC resin, light calcium carbonate, polyisocyanate block, silicone modified polyurethane resin in the mixing tank according to the formula;

[0028] b) Weigh the corresponding proportion of deionized water, heat it to 80±10°C, add it into the mixing tank with propeller in 2-4 times, stir for 2-10min each time, until the addition is complete;

[0029] c) Mixing and stirring: after all the raw materials are added, the propeller is stirred at a speed of 800-1200 rpm for 15min-30min;

[0030] d) extruder extrusion;

[0031] e) pelletizing;

[0032] That is, it is made into an impact-resistant and stretch-resistant plastic.

Embodiment 1

[0034] An impact-resistant and tensile-resistant plastic, comprising the following components: PVC resin 90g, light calcium carbonate 15g, polyisocyanate block 20g, dipropylene glycol dimethyl ether 10g, silicone modified polyurethane resin 20g After mixing the above materials Plastic sheets with a thickness of 24 mm are made by injection molding. The rubber sheet was subjected to a 200-pound function test and a 300-pound fracture test, both of which reached the BIFMA standard.

Embodiment 2

[0036] An impact-resistant and tensile-resistant plastic, comprising the following components: VC resin 80g, light calcium carbonate 17g, polyisocyanate block 23g, dipropylene glycol dimethyl ether 14g, silicone modified polyurethane resin 23g After mixing the above materials Plastic sheets with a thickness of 16 mm are made by injection molding. The rubber sheet was subjected to a 200-pound function test and a 300-pound fracture test, both of which reached the BIFMA standard.

Abstract

The invention relates to the technical field of plastic production and especially relates to impact-resistant stretch-resistant plastic. The impact-resistant stretch-resistant plastic comprises, by weight, 80-100 parts of PVC resin, 8-20 parts of light calcium carbonate, 15-30 parts of block polyisocyanate, 5-15 parts of dipropylene glycol dimethyl ether, 15-25 parts of organosilicone-modified polyurethane resin and 10-20 parts of deionized water. The PVC resin resists impact, stretch, aging, embrittlement and deformation and satisfies product special performance requirements.

Description

Technical field: [0001] The invention relates to the technical field of plastic production, in particular to an impact-resistant and stretch-resistant plastic. Background technique: [0002] Impact-resistant and stretch-resistant plastics are the most widely used polymers. It has good physical and mechanical properties, high impact strength, good chemical stability, good electrical properties, good product processing and machining performance, and is resistant to water, inorganic salts, acid and alkali, and is a widely used engineering material. However, the current resin plastics still have the disadvantages of low strength, poor surface abrasion resistance, weak flame retardancy and heat resistance in extreme cases, and poor surface gloss. Invention content: [0003] The purpose of the present invention is to address the deficiencies of the prior art, and to provide an impact-resistant and stretch-resistant plastic. The present invention solves the existing problems of ...
