2) make base-material with 5～20 parts of heavy weight percents, 10% polyvinyl butyral acetal ethanolic soln, high-temperature resisting pigment with 8～15 parts of weights of sand mill dispersion grinding, the gained slurry is again with after the montmorillonite nano slurry of 5～10 parts heavy monomethyl triethoxyl silane, 0.3～2 part of heavy poly(tributoxy titanium), 0.3～2 part heavy shrink sorbyl alcohol butyl laurate, 5～10 parts of weights mixes, leave standstill slaking 2 hours, and got the B component;
3) use before, with step 1), step 2) behind the gained A, B component thorough mixing, get final product through slaking in 0.5～5 hour.
The present invention reacts fluorine modified polysilicate ester with silicofluoric acid and tetraethyl silicate, and creatively use aziridine to activate polysilicates and monomethyl triethoxyl silane, make their self-crosslinking film-formings at normal temperatures, and use up-to-date coupling dispersion technology, pigment, filler, auxiliary agent fully are distributed to composite inorganic---in the organic binder matter, improve bonding force, the mechanical property of coating to metal base greatly, at normal temperatures, spontaneous curing becomes resistant to elevated temperatures and films.
Fluorine modified polysilicate ester is the main film forming substance of this coating, and making polysilicates with silicofluoric acid is critical process of the present invention.The polyvinyl butyral acetal ethanolic soln is the auxiliary film forming matter of coating, plays a crucial role to improving execution of coating adaptability; Poly-Butyl Phthalate is made coupling agent, and shrink sorbyl alcohol butyl laurate has the froth breaking effect; High-temperature resisting pigment, filler play heatproof and increase the effect of paint machine performance, and the monomethyl triethoxyl silane is the main film forming matter of coating, with poly-silicic acid crosslinking curing film forming, forms high temperature resistant radiation-resistant film forming matter.Aziridine is the filmogen in the coating---fluorine modified polysilicate ester and monomethyl triethoxyl silane, the activation promotor of self-crosslinking at normal temperatures.
That normal temperature self-drying temperature-resistant paint of the present invention has is high temperature resistant, radioprotective, exsiccant advantage at normal temperatures, is fit to the various metallic surfaces of brushing, is particularly suitable for using under the hot environment.
