Problems solved by technology

[0003] The market development prospects of domestic wear-resistant coatings are unanimously optimistic, but the main problems are the reduction of product prices and the improvement of comprehensive performance. The biggest problem with the performance of solvent transparent wear-resistant coatings is: to improve gloss while ensuring Solvent transparent wear-resistant coating has good various resistance properties, such as water resistance, abrasion resistance, etc.
Generally, the surface energy of inorganic particles is relatively high, and the affinity with organisms with low surface energy is poor.

Abstract

The invention relates to high wear-resistant epoxy coating, a preparation method of high wear-resistant epoxy coating and a high wear-resistant epoxy coating layer. The high wear-resistant epoxy coating provided by the invention is characterized by being prepared from an A component and a B component, wherein (1) the A component is prepared from the following raw materials in percentage by mass: 45 to 55 percent of epoxy resin, 3 to 5 percent of toughening agent, 3 to 5 percent of diluting agent, 5 to 10 percent of accelerator, 2 to 5 percent of silane coupling agent, 20 to 25 percent of abrasive aggregates, 5 to 10 percent of filler and appropriate percent of pigment; (2) the B component is prepared from the following raw materials in percentage by mass: 15 to 20 percent of MXDA (M-Xylylenediamine), 15 to 20 percent of IPDA (Isophorone Diamine), 3 to 5 percent of 1,3-BAC (1,3-bis(aminomethyl)-cyclohexan), 25 to 35 percent of polyether amine D230, 25 to 30 percent of styrenated phenol and 5 to 10 percent of TMPTA (Trimethylolpropane triacrylate); the A component and the B component are mixed according to a proportion of 1:5. The high wear-resistant epoxy coating disclosed by the invention has excellent wear resistance, high hardness, good heat resistance and water resistance, good chemical reagent corrosion resistance, high fullness, high construction efficiency, convenience in construction and a wide application range.

Description

technical field [0001] The invention relates to a wear-resistant epoxy coating, a method for its preparation and especially the prepared coating. The invention can be used in areas where industrial plants need to withstand greater wear resistance, impact resistance or more frequent operations; in production areas that require cleanliness and rough surfaces; it is suitable for public facilities and commercial sites, and has a wide range of applications. Background technique [0002] Many U.S., European, and Japanese patents introduce the use of nano-silica, nano-chromium dioxide, nano-cobalt dioxide, etc. or their composite nanomaterials for surface modification and dispersion in polymer resin matrices to prepare transparent wear-resistant coatings. Among them, the use of nano-silica or silica sol to modify the surface to make it easy to disperse in the polymer resin matrix to produce transparent wear-resistant coatings is the most reported. [0003] The market development p...
