Problems solved by technology

Chinese invention patent CN107236441A discloses a fire-proof, moth-proof and moth-proof coating for the restoration of ancient wooden structures. The coating not only has a good fire prevention effect, but also can maintain the cracks on the surface of ancient buildings and the special vicissitudes of time given to wood after restoration. feeling, so as to achieve the feeling of "repairing the old as old"; but the paint is added with 5-10% Bonet as a filler, the price is relatively high, and it has a great impact on the popularization and application of the paint, so it is necessary to study A low-cost fireproof coating for restoration of ancient wooden structures

Abstract

The invention discloses a low-cost fireproof coating for restoration of ancient wooden structures. The coating comprises the following ingredients: a wetting agent, a defoaming agent, a film-forming agent, an inorganic dispersant, a pigment, filler, hydrogenated coconut oil, petroleum asphalt, a co-solvent, a penetrant, an organic silicon polymer solution, ethyl acetate and water. As a recycled refractory material is used as the filler, the coating is not only low in price, but also very good in fire and corrosion resistance; the use amount of the petroleum asphalt is increased, and due to increase of the amount of infiltration, asphalt is integrated with wood, and thus an effect of permanent moth-proof can be achieved generally; after application, a woody surface has a special vicissitudefeeling along with time; to strengthen the infiltration effect of the petroleum asphalt, a combination of the co-solvent and the penetrant is used, and then a good infiltration effect can be achieved; due to addition of the hydrogenated coconut oil which is capable of retarding film formation and improving the infiltration effect, the petroleum asphalt can penetrate fully and evenly into the interior of the wood.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a low-cost fireproof coating used for repairing ancient wooden structures. Background technique [0002] The restoration of cultural relics such as modern historical buildings emphasizes "repairing the old as old", especially the restored parts should be consistent with the unrestored parts next to them, so as not to give people a feeling of "patching". When repairing ancient wooden structures, the biggest problem encountered is how to make the repaired parts have the same cracks as the unrepaired parts next to them. [0003] At the same time, in order to achieve a long-term repair effect, it is also necessary to add fireproof, moth-proof, and moth-proof ingredients to the paint. Chinese invention patent CN107236441A discloses a fire-proof, moth-proof and moth-proof coating for the restoration of ancient wooden structures. The coating not only has a good fire prevention effect,...
