Abstract

The invention discloses a flame-retardant polyvinyl chloride plastic and a preparation method thereof. The flame-retardant polyvinyl chloride plastic is prepared from 90-120 parts of polyvinyl chloride resin, 3-5 parts of calcium stearate, 4-5 parts of alkyl dimethyl betaine, 0.1-5 parts of a flame retardant, 5-10 parts of a heat stabilizer, 10-15 parts of calcium powder, 10-12 parts of a modifier, 1-3 parts of a coupling agent, 1-4 parts of an antioxidant and 5-10 parts glass fibers; the flame retardant is prepared from, by weight, 3-7 parts of kaolin, 1-3 parts of peat soil, 4-6 parts of calcium carbonate, 2-6 parts of sodium gluconate, 4-9 parts of chlorinated paraffin, 2-5 parts of mica powder, 1-2 parts of a smoke suppressant, 1-4 parts of steel powder, 8-10 parts of coconut shells, 1-2 parts of quartz sand, 2-10 parts of hollow glass microspheres, 3-5 parts of modified nanosilicon dioxide, 4-5 parts of graphene, 1-3 parts of aluminum hydroxide and 1-3 parts of a titanate couplingagent. The flame-retardant polyvinyl chloride plastic improves the flame retardancy and reduces the cost.

Description

technical field [0001] The invention relates to the technical field of flame-retardant polyvinyl chloride plastics, in particular to a flame-retardant polyvinyl chloride plastic and a preparation method thereof. Background technique [0002] PVC material is polyvinyl chloride, which is one of the largest plastic products in the world. PVC plastic has the advantages of light weight, beautiful appearance, convenient construction, and good flame retardant performance. It has become the fourth largest type of building material after steel, wood, and cement. It is used in suitcase artificial leather, handbag artificial leather, agricultural production film, card holder , Cable pipe, plate, wire and other fields. Polyvinyl chloride is a translucent, general-purpose thermoplastic synthetic resin. As a frequently used PVC material in building construction, if the performance of flame retardant and smoke suppression is not high, it will not only fail to prevent the spread of fire a...
