Abstract

The invention provides a flame-retardant organic silicon surfactant and application thereof to preparation of flame-retardant polyurethane rigid foam. A general formula of the flame-retardant organicsilicon surfactant is MDxD'yM, wherein M is selected from any one of (CH3)3SiO1/2 and (CH3)2RSiO1/2; D refers to (CH3)3SiO2/2; D' refers to (CH3)2(R)SiO2/2; x+y refers to 5-50, y refers to 3-13; R isselected from at least one of unblocked polyether portions and at least one radicals containing benzene rings. The organic silicon surfactant is capable of improving flame retardation of polyurethanerigid foam; especially in application to solar water heaters, high flame retardation of polyurethane foam plastic can be achieved without adding of flame retardants. In addition, the flame-retardant organic silicon surfactant has advantages of high fluidity and high storage stability in combined materials.

Description

technical field [0001] The invention relates to the field of polymer chemical industry, in particular to surfactants, in particular to a flame-retardant organic silicon surfactant and its application. Background technique [0002] New energy is one of the five most decisive technological fields in the world economic development in the 21st century. Solar energy is a clean, efficient and inexhaustible new energy source. In the construction industry, polyurethane insulation panels provide excellent insulation. In practice, governments of various countries regard the utilization of solar energy resources and polyurethane insulation boards as an important part of sustainable development strategies. Due to the advantages of heat insulation, low density and high specific strength, polyurethane rigid foam is widely used in the solar energy industry and building insulation. After using the transition blowing agent HCFC-141b instead of CFC-11 in the market, it still has depletion ...
