The invention relates to the technical field of rubber and plastic products, and proposes a non-combustible rubber-plastic foam product with a combustion performance of Class A, comprising the following components in parts by weight: 10-15 parts of nitrile rubber and 4-7 parts of polyvinyl chloride resin , 8 to 12 parts of filler, 2 to 3 parts of modified flame retardant, 2 to 4 parts of protective wax, 4 to 7 parts of foaming agent, 0.2 to 0.5 parts of active agent, 1 to 3 parts of accelerator, and 0.1 to 0.1 part of vulcanizing agent. 0.3 part, the modified flame retardant includes the following components by weight: 100 parts of magnesium hydroxide, 1 part of methacryloxypropyl trimethoxysilane, 20 parts of triethyl phosphate, fatty alcohol polyoxyethylene 0.5 part of vinyl ether. Through the above technical solutions, the problems of uneven dispersion and easy agglomeration of the flame retardant magnesium hydroxide in the rubber and plastic products in the prior art are solved. |
