Problems solved by technology

In order to reduce the amount of smoke, a smoke suppressant can be used instead of a flame retardant that generates a large amount of smoke and added to the polymer material, such as the use of inorganic flame retardants such as aluminum hypophosphite, ammonium polyphosphate, phosphite, magnesium hydroxide, hydrogen One or more mixtures of alumina and polysiloxane flame-retardant polyvinyl chloride to reduce the amount of smoke and have higher safety, but the flame-retardant efficiency of this inorganic composite flame retardant is low, which meets the requirements of flame-retardant materials When required, the addition amount is very large, which greatly reduces the mechanical properties of the material
In order to meet the requirements of high-efficiency flame retardancy and smoke suppression at the same time, multi-element synergistic flame-retardant and smoke suppressant compounds containing silicon, nitrogen, phosphorus, and halogen have been prepared, such as dimethyl-terminated dioxysilane polymers. Oxysilane or dimethyldiethoxysilane and terminal glycol are reacted in an organic solvent to synthesize a dimethyl-terminated dioxysilane polymer. This kind of flame retardant has both flame retardancy and smoke suppression, and is suitable for use in It can be used as a flame retardant plasticizer for polyvinyl chloride, polyurethane, epoxy resin, unsaturated resin, etc., but due to the complicated operation, high cost, and the use of organic solvents, the waste liquid is toxic, the plasticizing efficiency is low, and the durability of the flame retardant is relatively low. Difference
[0003] At present, the flame retardant method of polymer materials is mainly to add flame retardants, and the flame retardants are mainly aluminum, magnesium, zinc borate and composite metal oxides, etc., but due to the large amount of addition, the mechanical properties of the material are greatly reduced , it is difficult to meet the application requirements

Description

Technical field [0001] The invention relates to a polyvinyl chloride membrane structural material, in particular to a flame-retardant and smoke-suppressing polyvinyl chloride membrane structural material. Background technique [0002] Polyvinyl chloride (PVC) membrane materials have excellent comprehensive properties and are widely used in construction, sports, leisure and other fields. However, the large amount of plasticizers used in the processing of PVC membranes has led to a substantial decrease in the flame retardant properties of PVC membranes, and It releases a large amount of toxic gas and smoke during the combustion process, which limits its application and is also easy to cause fire hazards and economic losses. In order to improve the flame-retardant performance of PVC film materials and reduce the amount of smoke generated, inorganic flame retardants and smoke suppressants have been used to synergize flame-retardant polymer materials. For example, inorganic flame reta...
