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 ...
