Abstract

The invention discloses high-flame-retardant combined polyether for floors, and belongs to the technical field of polyurethane foam plastics. The high-flame-retardant combined polyether comprises thefollowing components in parts by weight: 20-50 parts of flame-retardant polyether; 50-70 parts of a flame retardant polyester; 0-10 parts of a cross-linking agent; 2-4 parts of a foam stabilizer; 10-18 parts of a catalyst; 0.5-1.5 parts of deionized water; 30-60 parts of a halogen-free flame retardant; 25-50 parts of dichlorofluoroethane; 200-280 parts of diphenylmethane diisocyanate; the productis low in heat conductivity coefficient and high in bonding strength, the heat conductivity coefficient is generally smaller than 0.03 W / m.K, the heat preservation performance is excellent, the building thickness can be reduced, and the use space is increased; through formula adjustment, the polyurethane material can reach B1-grade flame retardance; by improving the formula of the material, the indoor sound insulation and shock resistance effects can be improved without reducing the heat preservation performance, the environmental pollution in the construction operation process is small, and the material has the characteristics of simplicity and convenience in operation, short curing period, high construction speed and the like.

Description

technical field [0001] The invention belongs to the technical field of polyurethane foam plastics, and in particular relates to a high flame-retardant composite polyether for floor surfaces. Background technique [0002] Polyurethane rigid foam is a polymer composite material with superior performance. It has the advantages of low density, high strength, good thermal insulation effect, and high bonding strength. It is recognized as the best thermal insulation material, so it is mostly used in home appliances and panels. , pipelines, containers, construction materials, and ship supplies, etc. With the improvement of residents' living standards, the requirements for housing energy saving, emission reduction, and sound insulation and noise reduction are getting higher and higher. The use of thermal insulation materials can reduce building weight, increase thermal insulation performance, and reduce residents' electricity consumption. The polyethylene foam plastic used on the fl...
