0.5~5 part of absorbent, 0.5~5 part of light stabilizer, 0.5~5 part of deicer, the first 2~3 parts of adhesion promoters, the second bonding
0.5~1 part of accelerating agent, 0.05~2 part of catalyst；
The molecular formula of the silane modified polyether resin is：
The number-average molecular weight of the silane modified polyether resin is 16000~28000g/mol；
The catalyst is bis- (acetopyruvic acid) dibutyl tins and/or tetraethyl orthosilicate and bis- (acetyl group oxygroups) two fourths
The reaction product of base tin；
First adhesion promoters are amino silicane coupling agent；Second adhesion promoters are except amino silane is coupled
