Abstract

The invention discloses a calcium metasilicate modified spray-coating polyurea terrace coating. The calcium metasilicate modified spray-coating polyurea terrace coating is a double-component coating which is molded by spray-coating on site; and the calcium metasilicate modified spray-coating polyurea terrace coating consists of a component A and a component B, wherein the component A comprises 40-60 parts by weight of polyisocyanates, 35-50 parts by weight of half-prepolymer obtained by reacting polyether polyol and 0-10 parts by weight of diluents; and the component B comprises 35-50 parts by weight of amine-terminated polyether, 20-30 parts by weight of liquid-state amine chain extenders, 10-20 parts by weight of calcium metasilicate, 2 parts by weight of wetting dispersants and 0-3 parts by auxiliaries. The calcium metasilicate modified spray-coating polyurea terrace coating is quickly mixed and sprayed to the surface of a basic level by virtue of spray-coating equipment, so that the coating with high adhesion and flexibility is formed by quick reaction and solidification. The coating has functions of extremely high adhesion, high abrasion resistance, high impact resistance, solvent resistance and the like.

Description

technical field [0001] The invention relates to a modified calcium metasilicate spraying polyurea floor paint, which belongs to the field of floor materials. Background technique [0002] With the development of science and technology, people have put forward higher requirements for the cleanliness and beauty of the modern living environment and modern industrial production sites. Ordinary cement floors are easy to break and dust; terrazzo floors are not resistant to strong mechanical impact; granite splicing floors have seams and are not resistant to corrosion and penetration of chemical media; Therefore, there is a need to develop floor materials with better protection and decoration properties to avoid the above-mentioned disadvantages. The newly developed floor material needs to meet these characteristics: it is formed on site, durable, dustproof, anti-corrosion, strong in decoration, easy to repair, etc., and can also choose the corresponding floor type according to th...
