Abstract
The invention is a method for preparing environmental-protection, corrosion-resistant coatings, belonging to environmental-protection coating technical field, comprising the process steps of: blending and dissolving poly(vinyl butyral) in alcohol, and adding in assistant by 1-20 wt% of poly(vinyl butyral); taking corrosion inhibitor by 0.5-5wt% of poly(vinyl butyral) and adding the corrosion inhibitor in the solution, blending and fully dissolving; blending and adding inorganic salts in the prepared solution by 1-5wt% of poly(vinyl butyral) and blending for 30-60min; mechanically blending and obtaining various coatings, ranging from colorless and transparent to colored. And the coatings belong to environmental protection coatings, able to be used in anticorrosive protection of surfaces of copper, Al-Mg alloy, steel plate, and other metals, and especially applied to anticorrosive protection of metal surfaces on the condition of requiring the coat to be very thin.
Description
Technical field
The invention belongs to the environment-friendly materials technical field, a kind of preparation method of environment protection type corrosion resistant wear-resistant paint particularly is provided.
Background technology
The protection of metallic substance and protection against corrosion are the important topics that improves metal work-ing life, safeguards the metallic substance performance, and important method wherein is coated with organic coating at metallic surface exactly.The anticorrosion protection major requirement material of metallic substance has the ability and the mechanical property of good anti-various environmental corrosions.Anti-corrosion of metal corrosion material at present commonly used mostly contains benzene series thing such as benzene, toluene, chloroform etc., in construction and use environment and human body is caused bigger harm.Along with the growing interest of people, need to develop the novel environment protective antiseptic protection material that does not contain hazardous solvents such as benzene series thing to environment and health.And, in order to reach anticorrosion ability preferably, mostly adopting the thick film processing, coating will even reach more than 100 microns for the 30-50 micron, and also very insufficient for the research and development of the very thin about anticorrosive below 10 microns of coating.
Polyvinyl butyral acetal has the transparency of height, good photostabilization, water tolerance, film-forming properties and shock resistance, and nontoxic, do not have smell, non-corrosiveness, glass, synthetic glass, metal, timber, pottery, leather, fiber and other material have good adhesion property, can be used as coating, printing ink, tackiness agent etc.It is the method that main raw material prepares derust and rust-proof paint that patent CN1116223 has described by vinyl-formal resin or polyvinyl butyral resin, this lacquer have with good, the antirust life-span length of metallic cohesion, fast drying, easy to use, cost is low, filming can anti-180 ℃ of advantage such as high temperature, but coating composition complexity, coat-thickness is thicker just to have better preservative effect, coating has color, is not suitable for the requirement of colourless transparent coating material; Patent CN1186095 provides the method by the paint of polyvinyl butyral acetal, rosin phenolic resin, oxalic acid, phosphoric acid and the mixed solvent mainly be made up of dimethylbenzene, zinc phosphate, water, ethanol, it has the derusting rust-proofing dual-use function, also have advantages such as oil resistant, alkali, brine corrosion, broad application temperature range, long service life, but should paint as mixed solvent with dimethylbenzene, toxicity is big, does not meet environmental requirement; Patent CN1228800 provides with zinc powder and has contained the preparation method that ethanol, tetraethyl silicate, polyvinyl butyral acetal, water and ortho-phosphoric tetraethyl silicate prepare anticorrosive composite and its basic ingredient tackiness agent, the stability of the antiseptic property of composition, the stability of tackiness agent, freshly prepd composition all improve a lot to, the composition that this method obtains mainly contains zinc powder to the Corrosion Protection of metal and provides, because the restriction of zinc particle size, coat-thickness is thicker, is difficult to be fit to the very requirement of shallow layer.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of environment protection type corrosion resistant wear-resistant paint, is main raw with the polyvinyl butyral acetal, by adding the method for inhibiter, inhibiter compound system and other auxiliary agent configuration environment protection type corrosion resistant wear-resistant paint.The thinner that this coating uses is ethanol, the construction and use in to environment and body harmless; Owing to add inhibiter and compound system, the antiseptic property under the very thin condition of coating is just very excellent, is particularly useful for the anticorrosion protection of metallic surface under requirement coating very thin (as less than the 5 μ) condition; This coating water white transparency can keep the gloss of metal itself.This dope viscosity can be regulated, and construction easily can be selected technologies such as brushing or spraying.
Polyvinyl butyral acetal of the present invention comprises the product of different process, different molecular weight.The sustained release dosage that uses uses for one or more heterogeneous ring compounds mix.Heterogeneous ring compound mainly comprises: benzotriazole and derivative, 2-mercaptobenzothiazole and derivative, benzoglyoxaline and derivative, benzoxazole and derivative etc.Add molybdate, halogenide etc.Inhibiter can be formed compound system with inorganic salt, further improves Corrosion Protection and also can improve the abrasion property energy simultaneously.Select alcohols such as ethanol, butanols etc. for use, solvent such as non-benzene series thing such as ketone such as acetone, butanone etc. is a thinner.Various auxiliary agents be can add and the bonding force and the execution of coating performance of coating and metallic surface improved; Also can add the coating that various fillers obtain different colours and viscosity.
The present invention is main raw material with the polyvinyl butyral acetal, prepares the environment protection type corrosion resistant wear-resistant paint by adding other component, and concrete preparation technology is as follows:
