Problems solved by technology

[0004] Most of the existing surface treatment agents for solid powder are acrylic block copolymers. Although they can also have a certain dispersion effect, they cannot meet the requirements of use, mainly because the compatibility of such treatment agents with polyurethane is not good. Good and not flame retardant

Abstract

The invention discloses a silicon-containing flame retardant polyether surface treating agent. The silicon-containing flame retardant polyether surface treating agent contains three flame retardant elements including phosphorus, nitrogen and silicon, has the average molecular weight of 1,020-4,720, has the functionality of 6 and is a deep yellow transparent liquid. According to the preparation method, polyether polyol or polyether polyamine reacts with phenyl dichlorophosphate to generate flame retardant polyether, gamma-aminopropyltriethoxysilane is added, and the silicon-containing flame retardant polyether surface treating agent is prepared, wherein the gamma-aminopropyltriethoxysilane chain segment can be combined with a solid inorganic flame retardant through chemical bonds, and the polyether polyol chain segment and a polyether component for preparation of polyurethane resin have good compatibility. The surface treating agent has a flame retardant function, thus, solid inorganic flame retardant particles treated through the silicon-containing flame retardant polyether surface treating agent can be taken as flame retardant master batch and added to a formula material of polyurethane, and polyurethane foam with the solid inorganic flame retardant uniformly dispersed is obtained.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a flame retardant surface treatment agent and its preparation method and application, in particular to a silicon-containing flame-retardant polyether surface treatment for a solid inorganic flame retardant of flame-retardant polyurethane Agents and their preparation methods and applications. Background technique [0002] Polyurethane foam is widely used in refrigeration, construction, automobile and other industrial fields due to its light weight, high strength, excellent electrical insulation and low thermal conductivity. However, the porous cellular structure of polyurethane foam increases its contact area with air, making it highly flammable. In recent years, there have been more and more reports of fires caused by polyurethane foam igniting, so it is very necessary for it to be flame retardant. [0003] At present, the flame retardants used in polyurethane foam are ...
