Embodiment 1

[0010] A PVC formula of the present invention is made of the following raw materials in parts by weight: 70 parts of PVC resin, 3 parts of calcium stearate, 4 parts of zinc oxide, 6 parts of hexamethylphosphoric triamide, 1 part of anti-impact agent, chlorinated 2 parts of paraffin, 0.7 parts of additives.

[0011] The auxiliary agent is composed of one or more than two kinds of plasticizer, wetting agent and stabilizer.

Embodiment 2

[0013] A PVC formula of the present invention is made of the following raw materials in parts by weight: 90 parts of PVC resin, 6 parts of calcium stearate, 7 parts of zinc oxide, 8 parts of hexamethylphosphoric triamide, 2 parts of anti-impact agent, chlorinated 3 parts of paraffin, 1.3 parts of additives.

[0014] The auxiliary agent is composed of one or more than two kinds of plasticizer, wetting agent and stabilizer.

Embodiment 3

[0015] Embodiment 3 is the optimal embodiment of the present invention:

[0016] A PVC formula of the present invention is made of the following raw materials in parts by weight: 100 parts of PVC resin, 8 parts of calcium stearate, 7 parts of zinc oxide, 7 parts of hexamethylphosphoric triamide, 1.4 parts of anti-impact agent, chlorinated 4 parts of paraffin, 0.8 parts of additives.

[0017] The auxiliary agent is composed of one or more than two kinds of plasticizer, wetting agent and stabilizer.

[0018] To sum up, the PVC pipe produced by using this formula can enhance the impact resistance and strength, and the added hexamethylphosphoric acid triamide can not only greatly improve the oxidation resistance of PVC pipe, but also has a relatively low cost, which is suitable for popularization and application .

Abstract

The invention discloses a PVC formula. The PVC is prepared from, by weight, 100-120 parts of PVC resin, 8-11 parts of calcium stearate, 7-10 parts of zinc oxide, 6-8 parts of hexamethylphosphoramide, 1-2 parts of an impact resistant agent, 4-6 parts of chlorinated paraffin and 0.5-1.3 parts of auxiliaries. The PVC formula has the advantages that for PVC pipes manufactured through the formula, the impact resistant property and strength can be enhanced, by means of added hexamethylphosphoramide, the antioxidant property of the PVC pipes can be greatly improved, the cost is low, and the PVC formula is suitable for application and popularization.

Description

technical field [0001] The invention relates to plastic formulations, especially a PVC formulation. Background technique [0002] The main component of PVC pipe is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. PVC is deeply loved in the world today, and it is quite a popular and widely used synthetic material. PVC pipe is a mature pipe, mainly used in water supply and drainage projects. PVC pipe has the advantages of acid resistance, alkali resistance, corrosion resistance and high strength, but its impact resistance is relatively poor. Contents of the invention [0003] The object of the present invention is to provide a PVC formulation that solves one or more of the above-mentioned problems in the prior art. [0004] In order to solve the above problems, the technical solution of the present invention is: a PVC formulation, its innovation point is: it is made of the following raw materials in parts by wei...
