A kind of acid-alkali corrosion-resistant water-resistant wear-resistant floor coating and preparation method thereof

Abstract

The invention discloses an acid-base corrosion-resistant, water-resistant and wear-resistant floor coating and a preparation method thereof. The components and weight proportions of the coating are: polyether-polyisocyanate prepolymer solution 50%-80%, BS965 hydroxyl Acrylic resin 17.5%-7%, polymer 6101 epoxy resin polymer 2.5%-1%, 582-2 amino resin 1.5%-0.6%, pigment 18%-7%, xylene 8%-3%, butyl acetate Ester 2%-1%, BYK defoamer 0.2%-0.06%, 1% methyl silicone oil 0.2%-0.06%, organic soil 0.5%-0.2%. Compared with the current similar products, the product of the present invention has higher bonding strength to the substrate, better wear resistance, excellent water resistance, boiling water resistance, oil resistance, chemical resistance and detergent resistance, and the coating film is hard Good wear resistance and scratch resistance, convenient construction, and broad application space.

Description

technical field [0001] The invention relates to a coating, in particular to an acid-base corrosion-resistant, water-resistant and wear-resistant floor coating. The coating is suitable for the floors of various chemical production workshops, commercial and school floors, sports and leisure venues, smelting and industrial manufacturing workshops, Anti-corrosion use for the ground of computer workplaces, the ground of GMP pharmaceutical dust-free purification sites and other facilities. Background technique [0002] At present, in the field of anticorrosion of floor coatings, epoxy floor coatings and polyurethane floor coatings are mostly used, and their comprehensive performance is affected by their film-forming substances: although epoxy floor coatings have good adhesion to the substrate, but Due to the use of amine curing agent for curing, the degree of cross-linking is limited, and the abrasion resistance only reaches 0.03g / m 2 (abrasion), after a short period of use, scra...

Problems solved by technology

[0002] At present, in the anti-corrosion field of floor coatings, epoxy floor coatings and polyurethane floor coatings are mostly used, and their comprehensive performance is affected by their film-forming substances: although epoxy floor coatings have good adhesion to the substrate, but Due to the use of amine curing agent for curing, the degree of cross-linking is limited, and the abrasion resistance only reaches 0.03g / m 2 (abrasion), after a short period of use, scratches and stains will appear on the surface of the floor; although the wear resistance of polyurethane floor coatings is higher than that of epoxy floor coatings, it is significantly improved, and the wear resistance reaches 0.02g / m 2 (abrasion), but its wear resistance is improved, its flexibility and physical and mechanical strength are reduced, and its adhesion to the substrate is worse than that of epoxy floor coatings, and it is easy to cause shedding after a short period of use.

In addition, polyurethane floor coatings generally use TDI prepolymers {TDI (toluene diisocyanate) is a commonly used polyisohydrogen ester, mainly free TDI will cause harm to the human body, mainly sensitization and irritation ;The cured property is brittle and the flexibility is insufficient} As a curing agent, the brittleness of the coating after construction is increased
