Description
Technical Field
The invention belongs to the technical field of high polymer sealing materials, and particularly relates to a solvent-free base coat for an assembly type building sealant, a preparation method and application.
Background
With the development of the existing building technology, the house industrialization has become a necessary trend of the house technology development because of the advantages of shortening the construction period, improving the safety, saving energy, protecting environment, saving cost, stabilizing the building quality, reducing labor cost and the like. The member used in the house industrialization is a prefabricated concrete member which can be processed in a factory, and the manufacturing process of the member comprises the steps of template manufacturing and installation, concrete preparation and transportation, member pouring, vibrating, curing, demoulding, stacking and the like. The surface treating agent and the release agent are often used in the processing process of the component, the release agent is prepared by taking mineral oil as a main raw material and adding wax and the like, the mineral oil can be subjected to saponification reaction with alkali in cement concrete to generate alkaline soap, and the alkaline soap is remained in concrete gaps so as to influence the adhesiveness of the sealant; meanwhile, in the process of manufacturing the prefabricated panels, a surface treatment agent is often coated to protect the surfaces of the prefabricated panels, which may cause difficulty in adhering the prefabricated sealant. In addition, since the cement member is a porous material, after soaking in water, water slowly permeates into the bonding surface of the assembly sealant and damages the surface layer, thereby deteriorating the bonding effect of the assembly sealant after soaking in water.
In order to improve the normal temperature and water immersion bonding result of the assembly type sealant on the surface of a cement substrate, the surface of the substrate is generally required to be treated by using a primer. Chinese invention patent CN104559758A reports a primer coating liquid for an assembly type sealing polyether sealant, and the solvent content of the primer coating liquid is more than 50%. Chinese invention patent CN108047923A discloses a base coating liquid for a modified silicone sealant for an assembly type building, wherein the solvent content of the base coating liquid is 49-68%.
Common solvents in the existing bottom coat are toluene, xylene, acetone, ethyl acetate, butanone, butyl acetate and cyclohexanone; because the cement base material has a porous structure, the permeability of the primer is good, the using amount of the primer is large, and the solvent is seriously volatilized. The volatilization of a large amount of solvents, particularly benzene solvents, has strong carcinogenic risk and seriously affects the human health, so that the development of the solvent-free base coat has important significance for protecting the health of operators and the environment.
