Wear-resistant pressure-resistant epoxy paint and preparation method thereof

Abstract

The invention discloses a wear-resistant pressure-resistant epoxy paint, which is characterized by being prepared from the following raw materials by weight: 70-75 parts of E-42 epoxy resin, 2-3 parts of ethylene glycol ethyl etheracetate, 10-12 parts of polyamide resin, 10-12 parts of asphalt, 1-2 parts of 2-methylimidazole, 10-14 parts of phenolic resin, 2-3 parts of dicyandiamide, 16-19 parts of talcum powder, 5-6 parts of barium metaborate, 1-2 parts of nano aluminum oxide, 1-2 parts of dibenzoyl peroxide, 10-12 parts of xylene, 4-5 parts of vinyl acetate, 7-9 parts of ethyl acetate and 3-4 parts of a dispersant. The dispersant involved in the invention improves optical performance, realizes even dispersion of the paint and maintains the stability of the paint. The wear-resistant pressure epoxy paint provided by the invention has the advantages of extremely strong corrosion resistance, rust resistance andsaline-alkaline tolerance on metal, high hardness, wear resistance, pressure resistance and difficulty in brittle fracture, makes up the insufficiencies of a traditional epoxy paint; in addition, the wear-resistant pressure-resistant epoxy paint has simple preparation technology and is particularly suitable for back protection for a metal plate.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a wear-resistant and pressure-resistant epoxy paint and a preparation method thereof. Background technique [0002] As an important coating, epoxy paint is widely used in the coating anti-corrosion process due to its good anti-corrosion performance. Can be used as primer and intermediate coat for metal products. The main advantage of epoxy paint is that it has strong adhesion to inorganic materials such as cement and metal; the paint itself is very corrosion-resistant; it has excellent mechanical properties, wear resistance and impact resistance; it can be made into solvent-free or high-solid paint; it is resistant to organic solvents , heat-resistant, water-resistant; non-toxic coating. The disadvantage is that the weather resistance is not good, and chalking may occur after long exposure to sunlight, so it can only be used for primers or interior paints; the decorat...

Problems solved by technology

The disadvantage is that the weather resistance is not good, and chalking may occur after long exposure to sunlight, so it can only be used for primers or interior paints; the decoration is poor, and the gloss is not easy to maintain; the requirements for the construction environment are high, and the coating film at low temperature The curing is slow and the effect is not good; many varieties need high temperature curing, and the investment in coating equipment is large
