Problems solved by technology

However, the existing water-based floor coatings still have problems such as poor wetting effect on the ground, poor adhesion, low gloss after painting, and difficult cleaning.
The post-cleaning of the floor requires a lot of manpower, material resources, and financial resources, especially the polyurethane elastic floor is more likely to be stained with dust, oil stains and other stains; and many floors are outdoors, exposed to wind and sun, and are easy to age; plus If the upper floor is cleaned without professional maintenance and maintenance, it is easy to damage the floor; these reasons lead to a shorter service life of the floor

Abstract

The invention relates to a matte super-hard weatherproof finishing material, which is composed of a component A and a component B. The component A comprises a polyurethane prepolymer, ethyl acetate, dibutyltin dilaurate, BYK-052, BYK-306, 600-mesh cobalt oxide and silicon dioxide; and the component B comprises hydroxyl-containing silicone resin and acrylic resin. The finishing material is sprayedon a constructed floor to improve yellowing and slippery floor materials to enable the floor material to have mechanical properties such as slip resistance, mildew proof, seepage prevention, weather resistance, and super-hardness based on pencil hardness. The finishing material is widely used in concrete-based, polyurethane-based, epoxy-based and other floors.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a preparation method and application of a matte superhard weather-resistant varnishing material. Background technique [0002] In order to create a good working and living environment, more and more production workshops, warehouses, office areas, sidewalks, classrooms, stadiums, etc. use brightly colored and high-performance floor coatings. However, the existing water-based floor coatings still have problems such as poor wetting effect on the ground, poor adhesion, low gloss after painting, and difficulty in cleaning. The post-cleaning of the floor requires a lot of manpower, material resources, and financial resources, especially the polyurethane elastic floor is more likely to be stained with dust, oil stains and other stains; and many floors are outdoors, exposed to wind and sun, and are easy to age; plus If there is no maintenance and maintenance by professionals during the later cle...
