Problems solved by technology

It has been confirmed that the mixed emulsion made of water-based epoxy and styrene-acrylic emulsion has poor compatibility. Although many additives are used and a large amount of toxic methyl glycol is added to prevent the emulsion from coagulating at low temperature, the resulting product is still Agglomeration failure occurs in a relatively short time
For coating products, it is difficult to commercialize products due to large sales volume, long transportation distance, long construction period and short shelf life
It has been confirmed that the water-based epoxy and styrene-acrylic emulsion cured products do not produce a chemical reaction to form a whole, but are simply physically blended, so the wear-resistant coating made by it has poor water resistance and is easy to crack

Abstract

The invention relates to an outdoor weather-resistant wear-resistant stain-proofing colorful anti-skid water-borne environment-friendly coating and a preparation method thereof. The water-borne environment-friendly coating comprises a first composition and a second composition, wherein the first composition is prepared from the following raw materials in parts by weight: 20-30 parts of a water-borne curing agent, 0.5-3 parts of nano-materials, 2-5 parts of mica, 30-60 parts of packing and 20-30 parts of water; and the second composition is prepared from the following raw materials in parts by weight: 70-80 parts of epoxy resin, 20-30 parts of hyperbranched polymer, 0.2-0.6 part of an ultraviolet absorbent and 0.2-0.6 part of an antioxidant; and the first composition and the second composition are packaged independently. The water-borne environment-friendly coating has excellent performance of good coating toughness, high strength, good adhesion, good weather resistance, good water resistance, good abrasion resistance, pollution resistance, no toxicity, environmental friendliness and the like; and the preparation method is simple, and is low in production cost.

Description

Technical field [0001] The invention relates to the technical field of ground coatings, in particular to an outdoor weather-resistant, wear-resistant, stain-resistant, colored, non-slip, and water-based environmentally friendly paint and a preparation method thereof. Background technique [0002] With economic development and technological progress, more and more colored pavements have appeared in our lives. Thin colored pavements have gradually become the market due to their convenient construction, little damage to the original pavement, beauty and comfort, and low cost. Mainstream. Nevertheless, the colorful pavement we see is still limited to the anti-skid layer on the highway, which is mainly used for warning and anti-skid, indoor epoxy floor and various sports venues. Outdoor bicycle lanes, pedestrian streets, squares, parks, outdoor parking lots and scenic roads where colored pavements are most needed are hard to find. This is because currently the materials that can be ...
