Abstract

The invention discloses a concrete long-acting demolding coating and a preparation method thereof. The concrete long-acting demolding coating comprises the following raw materials in parts by weight: 50-90 parts of a crosslinking agent, 10-30 parts of resin, 10-30 parts of organic silicon, 10-25 parts of butanone, 10-40 parts of acetone, 20-50 parts of butyl acetate, 1-15 parts of ethanol, 20-80 parts of a curing agent, 0.1-1 part of ammonium water, 1-5 parts of a catalyst, 1-5 parts of ethyl ester, 5-20 parts of a monofunctional acrylate monomer, 5-20 parts of a multifunctional acrylate monomer, 20-40 parts of organic silicon modified acrylate, 20-40 parts of modified polyester acrylate and 0.1-1 part of a defoaming agent. According to the concrete long-acting demolding coating and the preparation method thereof, the cross-linking agent, the curing agent and the water are uniformly mixed in proportion to obtain a mixed solution, and the mixed solution and the butyl acetate are put into a reaction kettle to obtain a prefabricated reagent A, so that the problem that in the prior art, traditional oily and water-based de-coating agents need to be brushed for multiple times in the site construction process of an aluminum formwork, labor and time are wasted is solved, and the problem that construction personnel do not have responsibility in operation is avoided.

Description

technical field [0001] The invention relates to the technical field of release coatings, in particular to a long-acting release coating for concrete and a preparation method thereof. Background technique [0002] The traditional name of paint in China is paint. The so-called paint is applied to the surface of the object to be protected or decorated. It can be applied to the surface of the object by different construction techniques to form a solid film with firm adhesion, certain strength and continuity. Die coating is a kind of special material that can make the content slip out of the tank easily and keep its shape intact. It is made by dissolving cyclized rubber in an appropriate solvent, and then grinding it together with high melting point synthetic wax. Coating this Before the coating, epoxy phenolic paint should be used as the primer film to increase the sulfur resistance. There is also a process of adding synthetic wax slurry to the aluminum powder paint and coating ...
