The high temperature resistant and fire resistance of fiery glue, and by its special pattern, it will help further improve fire resistance；Three oxidations
Fire resistance of two antimony itself is not protruded, but the present invention is had found brominated polynary by carrying out repeated screening to a large amount of fire retardants
Alcohol, asbestos fibre, antimony oxide three coordinate, and flame retardant effect is very good, have the effect of cooperative flame retardant, and this point is from implementation
Example can be confirmed.
2nd, the antimony oxide, asbestos fibre, the bromine-containing polyols that play flame retardant effect are respectively put into soft and hard segments component,
Wherein, antimony oxide, asbestos fibre can be wrapped up in prepolymer in prepolymer preparation process, ensure there is one in hard section
Divide flame-retardant composition, bromine-containing polyols are placed in polyol component, subsequently enter polyurethane soft segment, finally ensure whole polyurethane point
More flame-retardant composition in son be present, and for being all mixed into a component, it can be ensured that it is more equal during mixing
It is even, and prepare and terminate the rear flame-retardant composition later stage and can be uniformly distributed in polyurethane, and also have to flame retardant effect certain
Lifting.
3rd, traditional adhesive for polyurethane, mostly using PPG as polyol component, it has hydrolysis
Advantage, but fire resistance is not so good as PEPA, the problem of selecting PEPA to face again intolerant to hydrolyzing, at present
There are some reports to point out that poly (propylene carbonate) polyalcohol has an excellent anti-hydrolytic performance, such as CN105482068A,
CN1865311A, CN106589300A etc., but also attempt to be used to prepare by poly (propylene carbonate) polyalcohol to build without document
