preparation example Construction

[0043] According to the method for preparing a solvent-free epoxy coating set according to the above-mentioned embodiments of the present invention, by using the above-mentioned raw materials together and further controlling the ratio of raw materials and preparation conditions, not only can the viscosity of the prepared coating be further reduced, but also can be further improved. The flexibility, impact resistance, adhesion and comprehensive anti-corrosion performance of the formed paint film, for example, in step (1), the resin and pigment can be more fully infiltrated by controlling the low-speed stirring time for not less than 4 hours, and the coated More perfect, it can not only fully reduce the viscosity, but also improve the compactness of the paint film. Among them, the solvent-free epoxy coating set prepared by the above method has an ultra-low viscosity after mixing, not more than 95KU, and the prepared solvent-free epoxy coating set has at least the following advant...

Abstract

The invention discloses a solvent-free epoxy paint set and a preparation method and application thereof, wherein the solvent-free epoxy paint set comprises a first component and a second component which are arranged in different containers respectively. The first component comprises, by weight, 20-25 parts of low-viscosity bisphenol A epoxy resin, 4-10 parts of hydrocarbon resin, 20-25 parts of alicyclic epoxy resin, 4-10 parts of an active diluent, 0.5-1.5 parts of a hyperdispersant, 0.5-1.5 parts of an anti-settling anti-sagging agent, 40-50 parts of low-oil-absorption pigment filler, 0.5-1.5 parts of a silane coupling agent, and 0.2-0.8 part of a defoaming agent. The second component comprises, by weight, 50-70 parts of a modified fatty amine, 20-40 parts of isophorone diamine and 5-10parts of an accelerant. The solvent-free epoxy paint set has very low viscosity, not higher than 95 KU, after being mixed, is suitable for direct spraying, and has excellent and long-acting integratedcorrosion resistance.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a solvent-free epoxy coating set and a preparation method and application thereof. Background technique [0002] As environmental protection policies become more and more stringent, high-solid coatings and solvent-free coatings have become products favored by the market. However, at present, the solvent-free epoxy coatings at home and abroad generally have high viscosity and difficult construction because they do not contain solvents. Add a large amount of diluent to reduce the viscosity before construction, and the solvent-free epoxy coating loses the meaning of environmental protection. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, an object of the present invention is to propose a solvent-free epoxy paint kit and its preparation method and ap...
