Abstract

The invention relates to a water long-acting anti-rot paint and the preparing method, which solves the problem how to provide the long effective date, sunlight-resistant, ultra-violet resistance water long-acting anti-rot paint. The method comprises the following steps: preparing high-modulus potassium lithium silicate solution with the mature electrodialysis technique; modifying with monomethyl triethoxysilicane and water epoxide modified propylene silicon resin; acquiring the organic silicon modified composite silicate inorganic resin; dispersing the powder material and adjuvant in the composite film material with dispersing coupling technique; forming composite phase solubility steady uniform painting system. The paint is provided with the high adhesive force, the high strength, ageing resistance, radio resistant and preservation, which is fit for the outdoor anticorrosion paint.

Description

technical field [0001] The invention relates to a water-based long-acting anticorrosion paint and a preparation method thereof. Background technique [0002] The validity period of general coatings is less than 10 years, and it is easy to age and deteriorate under sunlight, especially ultraviolet radiation. Contents of the invention [0003] The technical problem to be solved by the present invention is how to fill the above-mentioned gap in the prior art, and provide a water-based long-acting anti-corrosion coating with long validity period, sunlight resistance and ultraviolet resistance.
