Abstract

The invention discloses an epoxy flooring coating containing epoxide group organosilicon hybrid, its preparation method and its application. The epoxy flooring coating comprises the following ingredients: 100 parts of epoxy resin, 0.5-100 parts of epoxide group organosilicon hybrid, 0.1-4 parts of antifoaming agent, 0-30 parts of active diluent, 0.5-2 parts of levelling agent, 0.05-10 parts of dispersant, 0-40 parts of organic solvent, 2-16 parts of pigment, 20-200 parts of filling material, 10-80 parts of curing agent and 0-6 parts of promoter. The ingredients as described above are uniformly mixed to obtain the epoxy flooring coating of the invention. The epoxy flooring coating is prepared by the epoxide group organosilicon hybrid polymerized by hydrolytic polycondensation and traditional epoxy flooring coating. Compared with the traditional epoxy flooring coating, the invention has the advantages of good rigidity, wear resistance, stain resistance and heat resistance. The preparation method of the present invention has simple technology, easy raw material acquisition and convenient enforcement, as well as is beneficial to cost reduction in a practical production which has strong practicality.

Description

technical field [0001] The invention relates to an epoxy floor paint, in particular to an epoxy floor paint containing an epoxy-organosilicon hybrid, a preparation method and application thereof. Background technique [0002] Floor coatings are one of the important fields of industrial coatings, including several series of products such as epoxy, epoxy phenolic, chlorinated polyolefin and polyurethane. It has a wide range of applications, involving industrial plants, corridors, parking lots, and floors with special requirements for conductivity, spark resistance, chemical resistance, and nuclear radiation protection.
