Example Embodiment

[0010] Example 1

[0011] A far-infrared functional polyurethane matt varnish, in parts by weight: 40% soybean oil alkyd resin, 10% nitrocellulose, 5% nano ceramic powder, 5% matting agent, 0.01-2% additives, 10 solvents -20%, the balance is the curing agent, the balance is the curing agent ((Desmodur?) N3390 BA / SN aliphatic polyisocyanate hexamethylene polyisocyanate). The soybean oil alkyd resin is a main film-forming resin with abrasion resistance and a faster drying speed and a lower price. The nano-ceramic powder is a nano-scale natural composite inorganic ceramic powder capable of radiating far infrared. The nitrocellulose is one or two of nitrocellulose and nitrocellulose resin. The matting agent is white carbon black fumed silica. The auxiliary agent is one or more of leveling agent, defoaming agent, anti-settling agent, triethanolamine, polyvinyl polyamine, and polyamine-ethylene-vinyl acetate copolymer. The solvent is one or more of heavy aromatic hydrocarbons, buty...

[0012] Example 2

[0013] A far-infrared functional polyurethane matt varnish, in parts by weight: coconut oil fatty acid resin 35%, nitrocellulose 10%, nano ceramic powder 5%, matting agent 5%, auxiliary 0.01-2%, solvent 10 -20%, the balance is the curing agent, the balance is the curing agent ((Desmodur?) N3390 BA / SN aliphatic polyisocyanate hexamethylene polyisocyanate). The coconut oil fatty acid resin is the main film-forming resin. The nano-ceramic powder is a nano-level natural composite inorganic ceramic powder capable of radiating far infrared. The nitrocellulose is one or two of nitrocellulose and nitrocellulose resin. The matting agent is white carbon black fumed silica. The auxiliary agent is one or more of leveling agent, defoaming agent, anti-settling agent, triethanolamine, polyvinyl polyamine, and polyamine-ethylene-vinyl acetate copolymer. The solvent is one or more of heavy aromatic hydrocarbons, butyl acetate, butyl acetate, ethanol, ethyl acetate, isoprop...

[0014] Example 3

[0015] A far-infrared functional polyurethane matte varnish, in parts by weight: synthetic fatty acid resin 40%, nitrocellulose 8%, nano ceramic powder 5%, matting agent 5%, auxiliary 0.01-2%, solvent 10- 20%, the balance is the curing agent, the balance is the curing agent ((Desmodur?) N3390 BA / SN aliphatic polyisocyanate of hexamethylene polyisocyanate). The synthetic fatty acid resin is a main film forming with high fullness and weather resistance. The nano-ceramic powder is a nano-scale natural composite inorganic ceramic powder capable of radiating far infrared. The nitrocellulose is one or two of nitrocellulose and nitrocellulose resin. The matting agent is white carbon black fumed silica. The auxiliary agent is one or more of leveling agent, defoaming agent, anti-settling agent, triethanolamine, polyvinyl polyamine, and polyamine-ethylene-vinyl acetate copolymer.

Abstract

The invention discloses a polyurethane matte top-coat paint with a far infrared function, which comprises the following components in percentage by weight: 30-40% of modified fatty acid resin, 1-10% of nitrocellulose, 1-5% of nano ceramic powder, 1-5% of delustering agent, 0.01-2% of assistant agent, 10-20% of solvent and the balance of curing agent ((Desmodur) N3390BA/SN hexamethylene polyisocyanate of aliphatic polyisocyanate), wherein the modified fatty acid resin is selected from one or two of alkyd resin and acrylic resin, and the nitrocellulose is selected from one or two of nitrocotton and nitrocellulose resin. After the polyurethane matte top-coat paint with the far infrared function is formed into a film, under the irradiation of sunlight (especially ultraviolet rays), OH- is generated, which can be used for effectively removing indoor benzene, formaldehyde, sulfide, ammonia and odor substances and has a sterilization function. The polyurethane matte top-coat paint has the advantages of good environmental protection and infrared radiation function.

Description

technical field [0001] The invention relates to a paint in the field of chemical industry, in particular to a far-infrared functional polyurethane matt clear finish. Background technique [0002] Urethane matte varnish is a kind of furniture wood varnish commonly used by those skilled in the art, but the existing matt varnish for wood often has peculiar smell after use, and this polyurethane matt varnish is sprayed on furniture and wood surfaces in home decoration. The clear topcoat makes the environment for construction workers uncomfortable, and after the home is decorated, it takes a long time to be seated, and bacteria will still breed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a polyurethane matt clear topcoat with good environmental protection and infrared radiation function. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention i...
