Abstract

The invention provides double-component anti-corrosive decorative finishing coat for engineering machinery. The finishing coat is formed by mixing 72-75 parts of BC (Folic Acid)-1 resin, 0.3-0.5 part of a wetting dispersant, 0.2-0.4 part of organic bentonite, 18-20 parts of pigments, 0.2-0.9 part of an assistant, 1-2 parts of a metal drying agent, 9-11 parts of a modifying filler, 1-3 parts of a DBE (Dibasic Ester) solvent and 2-3 parts of butyl acetate. Compared with the conventional acrylic polyurethane coating, the finishing coat disclosed by the invention has high coating fullness, good fresh imaging performance, low toxicity and low price, satisfies or exceeds technical requirements of HG / T4339-2012 (other finishing coat), and is functional double-component coating.

Description

Technical field: [0001] The invention relates to the field of paints, in particular to a two-component construction machinery anti-corrosion decorative finish paint and a preparation method thereof. Background technique: [0002] The cured coating film of traditional acrylic polyurethane paint has superior chemical corrosion resistance, weather resistance, water resistance, gloss and color retention, wear resistance, and scratch resistance, so it has a wide range of applications in the fields of automobiles, machinery, transportation, electrical appliances, and aviation. application. However, the traditional acrylic polyurethane paint has defects such as poor fullness of the coating film and high price. With the development of my country's machinery industry, the requirements for the cost performance of construction machinery coatings continue to increase, making it difficult for traditional acrylic polyurethane paints to meet the coating requirements. The present inventio...
