Abstract

The invention discloses a halogen-free flame-retardant PVC material. The halogen-free flame-retardant PVC material is prepared from the following components in parts by weight: 100 parts of PVC resin, 50-100 parts of plasticizer, 5-10 parts of heat stabilizer, 2-4 parts of lubricant and 40-100 parts of halogen-free flame retardant, wherein the PVC resin is SG-3 type PVC resin; the plasticizer is prepared from dibutyl adipate, triethyl citrate, methoxyethyl oleate and glycerol monoacetate according to a weight ratio of 100:(50-80):(10-30):(3-10); the heat stabilizer is prepared from lead silicate and dibutyltin dilaurate according to a weight ratio of 10:(1-3); the halogen-free flame retardant is prepared from magnesium hydroxide and tetrakis(2,3-dibromopropyl)ethylene glycol diphosphate according to a weight of 10:(1-5). Compared with the prior art, the halogen-free flame-retardant PVC material disclosed by the invention greatly improves the tensile strength properties of PVC materials and has excellent heat 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...
