Problems solved by technology

At present, water-based varnishes mainly include solvent-based, water-soluble and powder-based. Although solvent-based varnishes are better in use, they contain a large amount of VOC (volatile organic compounds) and pollute the environment; powder-based wall paints have poor dispersion uniformity and are rarely used. ; Water-soluble varnish has good environmental protection performance, so it is loved by consumers
However, the existing water-based varnishes are poor in weather resistance, scratch resistance, distinctness of image, and aging resistance, and further improvement is needed

Abstract

The invention belongs to the field of water varnish, and in particular relates to nano diamond alkene containing novel aqueous varnish and a preparation method thereof. The nano diamond alkene containing novel aqueous varnish is prepared from the following raw materials in parts by weight: a first component, including 50-70 parts of a hydroxied acrylate emulsion, 0.5-7 parts of nano diamond alkene, 5-15 parts of deionized water, 0.1-0.6 part of a dispersing agent, 0.01-0.1 part of an anti-settling agent, 0.01-0.1 part of a defoaming agent, 0.2-1 part of a leveling agent, 2-4 parts of a coalescing agent, 0.3-2 parts of a thickening agent and 0.1-0.3 part of a pH adjusting agent; a second component, 15-25 parts of a curing agent and 1-3 parts of a cosolvent. The nano diamond alkene containing novel aqueous varnish is capable of solving the problems that conventional water vanish is relatively poor in weather resistance, scratch resistance, distinctness of image, and the like, is greatly excellent in glossiness, hardness, impact resistance, flexibility and weather resistance when being compared with those of conventional vanish, and is relatively good in environmental friendliness.

Description

Technical field [0001] The invention belongs to the field of water-based varnish manufacturing, and specifically relates to a novel water-based varnish containing nanodiamondene and a preparation method thereof. Background technique [0002] With the rapid development of industry, people’s requirements for material quality continue to increase. As the outermost layer of coatings for automobiles and furniture, varnishes play a vital role in the beauty and service life of objects. Water-based varnishes are a A kind of paint that does not contain coloring substances. The traditional water-based varnish is a paint made of resin as the main film-forming substance and solvent, which can keep the original texture of the article and form a smooth film after drying. At present, water-based varnishes are mainly solvent-based, water-soluble and powder-based. Although solvent-based varnishes have good results, they contain a large amount of VOC (volatile organic compounds) and pollute the en...
