Abstract

The invention discloses corrosion-resistant floor paint and a preparation method thereof, and belongs to the technical field of coatings. An adhesive for preparation can improve cohesive performance and adhesion strength and improve the bonding property between the floor paint and a wood floor, and then covalent crosslinking can be formed between the adhesive active agent and the floor, so that mechanical performance of the floor is improved, the floor paint can still be kept on the surface of the floor and does not fall off in a friction and wear process, and a protective layer is formed. Curing auxiliary resin for preparation enables the surface of the formed paint film to be smooth, and enable active components to be uniformly dispersed, so that cross-linking density of the floor paintis improved; F420 polyaspartic ester resin is added in a preparation process of the floor paint, so that ultraviolet aging resistance and wear resistance of the paint film are improved, durability ofthe paint film is improved, damage of the external environment to the paint film is reduced, and overall performance is improved. According to the invention, the problems of poor wear resistance and poor corrosion resistance of existing floor paint are solved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a corrosion-resistant floor paint and a preparation method thereof. Background technique [0002] Floor paint is a floor coating used for building interior floor coating finishes. The use of floor paint finishes is low in cost, light in weight, easy to maintain and update, and has good integrity. Its characteristics are impact resistance, high load, wear resistance; overall seamless, easy to clean; moisture-proof, dust-proof; general chemical corrosion resistance; non-slip or matte effect, etc. Solid wood flooring is the first choice for interior decoration. It is a floor material on the ground after the surface, side and other necessary processing of solid wood. It is a healthy and environmentally friendly product derived from nature. It preserves the original quality of wood. Natural texture, color and woody smell, the characteristics of natural solid wood make solid wood flooring hav...
