Rubber-plastic blended high-flame-retardant heat-insulating heat-preserving material

Abstract

The invention discloses a rubber-plastic-blended high-flame-retardant thermal-insulation material. The material is composed of a rubber-plastic blended material, a stabilizer, a filler, a plasticiser, a foaming agent, an active agent, a vulcanizing agent, an antiaging agent and a flame retardant. The heat-preserving material provided by the invention has weatherability and aging resistance of rubber, strength and plasticity of plastic, excellent flame retardant property and capability of being used as a heat-preserving, heat-insulating and sound-insulating material and applied in the engineering fields of building, transportation vehicles, ships, aerospace, etc.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, in particular to a rubber-plastic blended high flame-retardant thermal insulation material. Background technique [0002] Foam insulation materials mainly include two categories - polymer foam insulation materials and foam asbestos insulation materials. Polymer foam insulation materials have the advantages of low absorption rate, stable insulation effect, low thermal conductivity, no dust flying during construction, and easy construction. and convenient construction, the promotion and development are relatively stable, and the application effect is also good. However, the foam cotton is easy to be affected by moisture, easy to dissolve when immersed in water, has a small elastic recovery coefficient, and cannot be used in the part of the wall pipe and cannot be exposed to flames. [0003] There are three main types of polymer foam insulation materials, namely polyurethane, phenolic r...
