Abstract

The invention discloses a halogen-free flame-retardant PVC material, which is made of the following components in parts by weight: 100 parts of PVC resin, 50-100 parts of plasticizer, 5-10 parts of heat stabilizer, and 2-4 parts of lubricant and 40-100 parts of halogen-free flame retardant; the PVC resin is SG-3 type PVC resin; the plasticizer is composed of di-n-butyl adipate, triethyl citrate, methoxyethyl oleate And glycerol monoacetate is composed according to the weight ratio of 100:(50-80):(10-30):(3-10); the heat stabilizer is composed of lead silicate and dibutyltin dilaurate according to the ratio of 10: (1‑3) weight ratio; the halogen-free flame retardant consists of magnesium hydroxide, tetrakis (2,3-dibromopropyl) ethylene glycol bisphosphate according to the weight of 10: (1‑5) than composition. Compared with the prior art, the invention greatly improves the tensile strength performance of the PVC material, and simultaneously has excellent thermal aging resistance and flame retardancy.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant PVC material and a preparation method thereof. Background technique [0002] Flame retardant science and technology is a science developed to meet the needs of social safety production and life, prevent fires, and protect people's lives and property. It is a substance that can increase the flame resistance of polymer materials, and is mainly used in polymer materials such as plastics. , rubber, fiber, etc., and most of these materials are combustible, especially plastics. To apply them in transportation, construction, electrical equipment, aviation, spaceflight, etc., it is urgent to solve the problem of their combustion resistance. In the production process of polymer materials, in order to improve the corresponding functions, plasticizers, heat stabilizers, lubricants, flame retardants, etc. are added respectively, but these function imp...
