Formula of flame-retardant polyvinyl chloride (PVC) plastics

Abstract

The invention discloses a formula of flame-retardant polyvinyl chloride (PVC) plastics. The formula is characterized by comprising PVC and supplementary additives, wherein the supplementary additives include a flame retardant, a mildew preventive, an antistatic agent, a heat-resisting agent, a crosslink agent and a coupling agent, the flame retardant is triphenyl phosphate and ammonium polyphosphate, the mildew preventive is 8-hydroxyquinoline copper, the antistatic agent is sodium alkyl sulfate, the heat-resistant agent is 2-ethylhexyl thioglycolate, the crosslink agent is 2,5-dimethyl-2,5 bis(tert-butyl peroxy hexane and the coupling agent is aminopropyltriethoxysilane. The flame retardant is used for improving the flame-retardant property of the PVC plastics; by adding multiple assistants in the flame-retardant PVC plastics, the heat resistance and the antistatic property of the flame-retardant PVC plastics can be improved, the stability of the flame-retardant PVC plastics also can be improved, and the production cost can be reduced by accelerating the reaction speed and reducing the consumption of raw materials.

Description

technical field [0001] The invention relates to a plastic formula, in particular to a flame-retardant polyvinyl chloride plastic formula. Background technique [0002] Polyvinyl chloride is an important general-purpose resin with a wide range of uses. Its products can be seen everywhere from films, pipes, daily necessities to wire and cable sheaths, etc. However, polyvinyl chloride is a relatively flammable material with a high heat release rate when burning. High calorific value, fast flame propagation, decomposition to produce flammable gas carbon monoxide, etc., not easy to extinguish, easy to cause fire, and pose a huge threat to people's lives and property safety, which makes PVC products widely used in electrical appliances, high-rise buildings, coal mines, etc. Applications in many fields such as tunnels, tunnels, and decorations are restricted, and certain flame-retardant modifications are required. [0003] At present, the flame retardant modification of polyvinyl ...

AI Technical Summary

Problems solved by technology

[0004] At present, the means of flame retardancy of PVC plastics mainly adopts additive technology, that is, adding flame retardants to PVC, flame retardants mainly include aluminide, zinc borate, etc. The large amount seriously affects the physical and chemical properties of the plastic, or the product cost is too high due to the high price of the flame retardant, etc.
