Problems solved by technology

However, the promotion and application of water-based epoxy floor products in my country is not very sufficient, and the market share is not high. The main reason is that domestic investment in water-based epoxy floor paint product research and development, quality improvement, etc. Insufficient performance, such as poor strength and poor wear resistance, and the price of water-based epoxy floor paint products is generally high, resulting in no obvious competitive advantage of water-based epoxy floor paint

Abstract

The invention relates to the technical field of coating, and particularly relates to high-strength wear-resistant waterborne epoxy floor coating and a preparation method thereof. The waterborne epoxyfloor coating is prepared from a component A and a component B; the component A is prepared from the following raw materials: 30-50 parts of waterborne epoxy resin and 10-30 parts of water; the component B is prepared from the following raw materials: 20-50 parts of waterborne epoxy hardener, 10-30 parts of water, 10-60 parts of filler, 2-6 parts of wetting agent, 0.2-0.4 part of anti-foaming agent, 5-15 parts of calcium sulfate whisker, 1-5 parts of kieselguhr and 0.5-2 parts of nano cellulose. The waterborne epoxy floor coating has relatively high impact resistance and wear resistance without obviously increasing the production cost; the preparation method is simple and practical and easy to operate and has great economic and practical value.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-strength wear-resistant water-based epoxy floor paint and a preparation method thereof. Background technique [0002] Floor paint was first invented by Germany in 1934. It is mainly made of oil, tree material, color, solvent and other materials through many production processes such as mixing, dissolving, and dispersing. It can be divided into decorative floor paint Paint, heavy-duty floor paint, heavy-duty floor paint, etc., which have the characteristics of bright, real, beautiful, wear-resistant, waterproof, and anti-corrosion. Water-based epoxy floor paint has high adhesion, corrosion resistance, and excellent electrical insulation performance. Water-based epoxy floor paint has low odor and meets environmental protection requirements. In addition, there will be a small amount of water-based epoxy floor paint in the coating film after curing. The presence of moisture ...
