Abstract
The invention discloses a lightproof coating and a preparation method thereof, and relates to the technical field of production of coatings. The lightproof coating is prepared from 40-50 parts of an anionic self-crosslinked silicone acrylic emulsion, 15-20 parts of rosin, 1-5 parts of zirconia, 50-60 parts of heavy calcium carbonate, 5-10 parts of titanium dioxide and 15-20 parts of deionized water with the conductivity being smaller than 5[mu]S/cm. Compared with lightproof coatings in the prior art, the lightproof coating disclosed in the invention has the following advantages: the anionic self-crosslinked silicone acrylic emulsion is used as a main base material, the bond energy of a Si-O covalent bond in the silicone acrylic emulsion is higher than the energy bond of a C-C covalent bond, so the chemical stability is good; a siloxane monomer is hydrolyzed with the volatilization of water in the use process to generate a silanol condensate, and an acrylamide monomer makes a paint film have a three-dimensional space network structure, so the film has greatly improved adhesion and difficultly sheds after being combined with walls; and rosin, zirconia and deionized water with the conductivity being smaller than 5[mu]S/cm are added to further make the coating has good lightproof performance.
Description
Technical field
The present invention relates to coating manufacturing technology field, especially a kind of photo-stable coating and preparation method thereof.
