Abstract

The invention provides a flame-retardant and heat-insulating foamed material. The flame-retardant and heat-insulating foamed material is characterized by taking expanded perlite as aggregates, taking foamed material powder as fillers, and taking sodium silicate or organic adhesives such as phenolic resin and urea resin as an adhesive material. The flame-retardant and heat-insulating foamed material is produced by the following method: adequately mixing the expanded perlite with the foamed material powder, adding the adhesives and uniformly mixing, then adding the mixture in a press and performing press-forming. The flame-retardant and heat-insulating material provided by the invention has a structure with the uniformly-distributed expanded perlite and foamed plastic powder, flame-retardant and heat-insulating functions, and the characteristics of light weight, good weather resistance, high compression strength and low cost, can realize recovery of the cutting scraps and leftover materials of industrial foamed materials, and meets the requirements of the national related policies of energy saving and emission reduction.

Description

Technical field: [0001] The invention relates to a foam material / expanded perlite flame retardant and thermal insulation composite material and its preparation technology. Background technique: [0002] Insulation material is one of the very important materials in the construction industry. However, due to the limited flame retardant ability of traditional organic thermal insulation materials, it caused or indirectly caused many serious fires that harmed the lives and interests of the people. On September 25, 2009, the Ministry of Urban and Rural Development and the Ministry of Urban and Rural Development jointly formulated the "Interim Regulations on Fire Protection of Civil Building External Thermal Insulation System and External Wall Decoration" (Gong Tong Zi [2009] No. 46), which clearly stipulates: "The external thermal insulation materials of civil buildings The combustion performance should be grade A, and should not be lower than B 2 class. "After that, on March 1...
