Abstract

The invention relates to a flame-retardant elastic rubber-plastic wave thermal insulation material and a preparation method thereof. The flame-retardant elastic rubber-plastic wave thermal insulationmaterial comprises the following raw materials: an ethylene propylene diene monomer, butadiene styrene rubber, high styrene resin, dioctyl sebacate, a vulcanization accelerator, an active agent, an anti-scorching agent, a foaming agent, sulfur, an antioxidant, a light stabilizer and a composite flame retardant. Ethylene-propylene-diene monomer and a composite flame retardant are added; no polar substituent exists in the molecular structure of the ethylene propylene diene monomer; the molecular cohesion is low, a molecular chain can keep flexibility in a relatively wide range, and the flexibility and elasticity of the material are improved; by adding the composite flame retardant, heat can be absorbed to generate a thermal decomposition reaction, the temperature in a condensed phase can bereduced, the thermal decomposition speed of the material can be reduced, and a large number of active hydroxyl free radicals generated in the combustion process can be isolated, so that the flame retardant effect is achieved, and the elasticity and flame retardant property of rubber and plastic products are effectively improved.

Description

technical field [0001] The invention relates to the technical field of rubber and plastic preparation, in particular to a flame-retardant elastic rubber and plastic wave insulation board and a preparation method thereof. Background technique [0002] Rubber and plastic is the collective name of the rubber and plastic industries. They are all subsidiary products of petroleum. With the demand and application of technology and market becoming more and more extensive, the elasticity of rubber and plastic decreases during the use of rubber and plastic. In addition, rubber and plastic insulation The main components of the material are rubber and plastics, which have the common disadvantage of not being resistant to open flames. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a method for preparing a flame-retardant elastic rubber-plastic corrugated thermal insulation board with high elasticity and high flame retardan...
