Abstract

The invention belong to the technical field of photocureable coating and relates to waterborne UV type stainless steel protecting coating with excellent CNC resistance. The waterborne UV type stainless steel protecting coating comprises, by weight, 20-60 parts of waterborne polyurethane acrylate, 5-15 parts of monofunctional acrylate, 10-30 parts of talcum powder, 0.5-1.5 parts of gaseous siliconpowder, 0.1-0.5 part of waterborne leveling agent, 1-5 parts of waterborne photoinitiator and 20-50 parts of diluent. The UV type protecting coating has the advantages that by using the waterborne UVresin as the main body of the coating, adding filler and low-functionality-degree monomers and performing UV curing, a uniform protecting coating layer is formed on a stainless steel substrate, and the coating is good in CNC cutting resistance, high in adhesive force, excellent in cutting fluid resistance and cleaning agent resistance and ideal in impact resistance and spallation resistance.

Description

technical field [0001] The invention belongs to the technical field of photocuring coatings, and relates to a stainless steel water-based UV protective coating with excellent CNC resistance performance. Background technique [0002] The world releases 20 million tons of hydrocarbons into the atmosphere every year, of which 10 million tons are organic solvents, most of which are produced by the paint industry. In response to the above problems, countries around the world have successively formulated a series of environmental protection laws and regulations to reduce the environmental pollution of the coatings industry, such as the AIM (Architectural and Industrial Maintenance Coatings Rules) promulgated by the US Environmental Protection Agency in 1998, and the Atmospheric and Industrial Maintenance Coatings Rules implemented by the EU countries in 1986. Purification Technology Outline AT-Luft, etc. In the coatings industry, the limits on VOC emissions are becoming more and ...
