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, 0.5 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: 80 parts of PVC resin, 4.7 parts of calcium stearate, 5 parts of zinc oxide, 7 parts of hexamethylphosphoric triamide, 1.4 parts of anti-impact agent, chlorinated 2.6 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 provides a PVC (polyvinyl chloride) formula, which is prepared from the following raw materials in parts by weight: 70 to 90 parts of PVC resin, 3 to 6 parts of calcium stearate, 4 to 7 parts of zinc oxide, 6 to 8 parts of hexamethylphosphoric triamide, 1 to 2 parts of impact modifier, 2 to 3 parts of chlorcosane, and 0.5 to 1.3 parts of auxiliaries. PVC pipes produced by using the formula have the advantages that the impact resistance property and the strength can be enhanced, through adding the hexamethylphosphoric triamide, the oxidation resistance of the PCV pipes can be greatly improved, and the cost is relatively low. The PVC formula is suitable for popularization and application.

Description

【Technical field】 [0001] The invention relates to the technical field of plastic pipes, in particular to a PVC formula. 【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. 【Content of invention】 [0003] The invention provides a PVC formula, and the PVC pipe produced by using the formula can enhance the impact resistance and strength. [0004] In order to achieve the above object, the technical solution adopted by a PVC formula of the present invention is: a PVC formula made of the following raw materials in parts by weig...
