The patent near future that compound coating and place of its preparation method apply for ability in swimming of polyurethane of a kind of POSS/ is obtained formally batch. The invention is the same as aid university Yang Zhenglong, Qin Shen, Pu Hongting for the person.
As we have learned, POSS/ polyurethane ability in swimming is compound coating and its preparation method are: First the POSS that hydrolysis law preparation did not seal end, use KH-550 of silicon alkyl coupling agent to undertake to its Feng Duan is made so that one kind contains the POSS of amine radical again; this POSS and polyurethane of ability in swimming dispersive body undertakes chemical and compound preparation finally ability in swimming of polyurethane of a kind of POSS/ is compound coating. Compound coating has this the depth that invents preparation performance of good room temperature store, hardness and be able to bear or endure water property, and hear resistance is reached fight ultraviolet light function exceedingly good. Preparation method has craft to be mixed convenient and simply, high to quality of environmental free from contamination, film cost is low wait for an advantage, it is environmental protection of new generation green product of high-powered chemical industry, applicable besmears at the car furniture of lacquer of outfit, carpentry, building, office, leather, spin is arranged, a variety of domains such as coating printing and mechanical equipment.
