Embodiment 1

[0026] Ferment nylon-1212, 10g TiO with 100g petroleum 2 , 0.8g polyacrylate, 0.3g antioxidant 1010, 0.2g antioxidant 168 were prepared into a powder coating. The coating was applied on a tableware rack, the surface of the coating was smooth and clean, and the steel bar of the tableware rack was bent 360 degrees, and no cracks and coating peeling were seen on the base surface; soaked in 9% sodium chloride aqueous solution at 40°C No rust was found on the surface of the coating for 288 hours.

Embodiment 2

[0028] Prepare powder coating with 200g of petroleum fermented nylon-1212, 15g of epoxy resin E-12, and 10g of graphite. The coating was applied to a mechanical sliding bearing. Under the condition of a small amount of oil lubrication, the bearing had been running continuously for 2 years without falling off the surface and the wear was 0.04mm.

Embodiment 3

[0030] Prepare a powder coating with 100g petroleum fermented nylon-1212, 5g epoxy resin E-12, 0.1g bis-nitrile amine, 5g graphite, 10g aluminum oxide, and 1g polyvinyl butyral. The coating is applied to the inner wall of a ball mill roller, and the service life of the original equipment without powder coating is increased by 3 times.

Abstract

The present invention provides a new type anti-corrosion wear-resisting coating material for metal. Said coating material is made of petroleum fermentation nylon-1212 as base material and adding epoxy resin, solidifying agent, wear-resisting agent, lubricating agent, leveling agent, chemical inhibitor, optical stabilizing agent and pigment. Said coating material has excellent elasticity and flexibility, and has the good water-proofing property, impact resistance and can raise service life of machines, so that it has extensive application.

Description

[0001] Field: [0002] The invention belongs to the technical field of metal anti-corrosion and wear-resistant coatings, in particular to a metal anti-corrosion and wear-resistant coating mainly composed of petroleum fermented nylon-1212. Background technique: [0003] Coatings can be divided into two categories: solvent-based and powder-based. Most solvent-based coatings have safety hazards such as fire, poisoning, and air pollution because they contain organic solvents. At the same time, due to the long construction period of this type of coating and the waste of solvent resources, more and more application fields have been replaced by powder coatings in recent years. [0004] Powder coating is a coating that contains 100% solids and is applied in the form of powder. It is different from general solvent-based coatings. It does not use solvent as the dispersion medium, but uses air as the dispersion medium, which saves energy and resources. , Reduce environmental pollution,...
