Example Embodiment

[0033] Example 1

[0034] A metal anticorrosive material, comprising the following raw materials in parts by weight: 75 parts of epoxy resin, 25 parts of mixed solvent, 1.75 parts of toughening agent, 0.35 parts of defoamer, 10 parts of phenalkamine epoxy curing agent, and 2.2 parts of anti-aging agent , 0.8 part of antioxidant, 0.45 part of lubricant, 0.9 part of thixotropic agent, 2 parts of pigment and 20 parts of filler;

[0035] The mixed solvent is ethanol, methyl ethyl ketone and DBE in a weight ratio of 1:2:7.

[0036] The toughening agent is nano-silica or liquid polysulfide rubber. The elongation of the epoxy resin is low after curing, and the brittleness is large. When the bonding part is subjected to external force, it is easy to crack and develop rapidly, causing the anti-corrosion coating to crack; nano-dioxide Silicon has strong rigidity. When the cracks expand, they will deflect when encountering nano-silica particles, thereby absorbing energy and achieving the purpo...

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...
