Abstract

An anticorrosive primer for copper comprises the components in parts by mass as follows: 100 parts of isopropyl alcohol, 25-30 parts of phenolic novolac resin, 15-30 parts of butyl alcohol, 15-25 parts of polyvinyl acetate, 15-20 parts of zinc chromate, 50-60 parts of toluene, 10-15 parts of a corrosion inhibitor, 10-20 parts of alkyd resin, 3-15 parts of iron oxide red, 3-10 parts of chlorinated paraffin, 15-20 parts of carbon black, 10-15 parts of a dispersant and 5-10 parts of talc powder. The binding force of the primer to the copper is good, the adhesive force reaches grade 1, the shock strength is larger than 500 MPa, the flexibility is smaller than 1 mm, and the hardness is larger than 2 H; and the primer is good in corrosion resistance, convenient to construct, simple in process, free of organic solvents and capable of being widely produced and replacing existing materials.

Description

[0001] technical field [0002] The application belongs to the field of coatings, in particular to an anticorrosive primer for copper. [0003] Background technique [0004] Nano-hydrophilic coatings are specially used for air conditioners. The hydrophilic coatings used in air-conditioners are jointly developed by Xiangzheng Company, University of Science and Technology of China, Hefei University of Technology and other universities, and have obtained nano-hydrophilic film technology and low-cost, high-quality hydrophilicity. Nano-coating preparation process and coating technology. According to this process technology, the nano-hydrophilic coating produced is a nano-coating composed of many nano-components, which has many nano-effects, and the primary particle size of the nano-materials contained in it is between 7 and 80nm. The specific surface area is generally greater than 100㎡ / g. It shows excellent properties in materials, so it is widely used in rubber, plastic, stee...
