Abstract

The invention relates to combined polyether for flame-retardant bulk rigid polyurethane foams and an application method of the combined polyether and belongs to the technical field of the combined polyether. The combined polyether for the flame-retardant bulk rigid polyurethane foams is prepared from the following components including flame-retardant polyester polyol A, flame-retardant polyester polyol B, flame-retardant polyester polyol C, a crosslinking agent, a foam stabilizer A, a foam stabilizer B, a chemical foaming agent, a catalyst, a physical foaming agent, a flame retardant A and a flame retardant B. The combined polyether for the flame-retardant bulk rigid polyurethane foams is wide in raw material source and is low in cost. With the adoption of the combined polyether, the flame-retardant bulk rigid polyurethane foams prepared by the combined polyether are good in flame retardancy, low in thermal conductivity, good in airtightness and stable in quality performance. The invention also provides the application method of the combined polyether for the flame-retardant bulk rigid polyurethane foams. The application method is simple in process, is easily operated, is low in volatilization and is high in production efficiency without three wastes.

Description

technical field [0001] The invention relates to a combination polyether for flame-retardant bulk polyurethane rigid foam and an application method thereof, belonging to the technical field of combination polyether. Background technique [0002] Since the implementation of building energy conservation in my country in the 1980s, the external wall insulation materials are mainly inorganic insulation materials, such as rock wool, perlite, glass wool, and rubber powder polystyrene particles. These insulation materials are cheap, but the insulation effect is poor, the thermal conductivity is generally above 0.06W / M.K, easy to crack and leak, technically it is difficult to meet the 65% energy-saving standard. [0003] In recent years, fires involving building external insulation materials have successively occurred in Nanjing Central International Plaza, Harbin Jingwei 360-degree Twin Star Building, Jinan Olympic Sports Center, Beijing CCTV New Site Affiliated Cultural Center, Sha...
