Abstract

The invention relates to a GZ-12 novel environmentally-friendly high-performance solvent-free epoxy coating and its preparation method, especially relates to a novel environmentally-friendly solvent-free epoxy coating and its preparation method, and belongs to the technical fields of a coating and its raw materials. The GZ-12 novel environmentally-friendly high-performance solvent-free epoxy coating is composed of a part A and a part B, wherein the part A comprises 60-70 parts by weight of a specific modified epoxy resin Barrier B-828, 15-20 parts by weight of Cardura E10P, 0.2-2 parts by weight of aerosil, 10-20 parts by weight of a functional filler, and 0.5-1.0 part of a functional assistant; the part B comprises 20-25 parts by weight of an alicyclic amine resin; and the weight ratio of the part A to the part B is 4-5:1. The GZ-12 novel environmentally-friendly high-performance solvent-free epoxy coating has the advantages of excellent resistances to the corrosion of acids, alkalis, salts, organic solvents and strong-oxidizability mediums, strong adhesion, good abrasion resistance, good flexibility, strong permeability, fast drying, simple construction, thick formed film, less application amount, non-toxicity, no benzene and the like, and is an ideal novel solvent-free epoxy anticorrosion coating which accords with environmental protection requirements and has a high cost performance.

Description

(1) Technical field [0001] The present invention relates to GZ-12 new environment-friendly high-performance solvent-free epoxy coating and its preparation method, especially a new type of environment-friendly solvent-free epoxy coating and its preparation method, and specifically relates to special modified epoxy resin as matrix film-forming substance The invention discloses a preparation process of a two-component solvent-free epoxy paint with excellent corrosion resistance such as acid and alkali, and belongs to the technical field of paint. (2) Background technology [0002] Coating is an industry that has developed very rapidly in recent years. However, although many coatings can achieve a certain anti-corrosion effect, under heavy corrosion, such as harsh acid, alkali, salt, organic solvent, strong oxidizing medium, etc., this It is difficult for a general industrial anti-corrosion coating to achieve a lasting anti-corrosion effect. At the same time, because the marine...
