Metal anticorrosive material, and preparation method thereof

Abstract

The invention provides a metal anticorrosive material, and a preparation method thereof, and belongs to the field of anticorrosive material. The metal anticorrosive material comprises following raw materials, by weight, 70 to 80 parts of epoxy resin, 20 to 30 parts of a mixed solvent, 0.5 to 3 parts of a flexibilizer, 0.2 to 0.5 part of an antifoaming agent, 4 to 16 parts of a phenolic amine epoxy hardener, 1.2 to 3.2 parts of an anti-aging agent, 0.1 to 1.5 parts of an anti-oxidant, 0.1 to 0.8 part of a lubricant, 0.5 to 1.3 parts of a thixotropic agent, 1 to 3 parts of a pigment, and 15 to 25 parts of a filling material. The preparation method comprises following steps: 1, raw material weighing; 2, dissolving; 3, blending; 4, defoaming; and 5, impurity removing. The metal anticorrosive material is excellent in levelability, thixotropy, and impervious performance, high in surface toughness and adhesive force, is more friendly to the environment, is longer in service life; and no pin hole is formed.

Description

technical field [0001] The invention belongs to the field of anti-corrosion materials, and in particular relates to a metal anti-corrosion material and a preparation method thereof. Background technique [0002] With the rapid development of China's economic construction, construction, transportation, petrochemical, energy, machinery and other fields have achieved rapid growth, but environmental pollution has become increasingly serious, and metal corrosion in industries such as machinery, electronics, and construction has also increased accordingly. The more serious, according to incomplete statistics, the annual direct economic loss caused by corrosion accounts for about 1%-4% of the total output value of the national economy; therefore, it provides a broad development space for anti-corrosion materials. At present, the main problems of the existing anticorrosion materials are: poor adhesion to the base material, low curing content, and large environmental pollution. [0...
