A kind of crystal whisker wear-resistant ultraviolet ray solidified paint and preparation method thereof
Technical field
A kind of crystal whisker wear-resistant ultraviolet ray solidified paint and preparation method thereof relates to a kind of wear-resistant paint that can be used for timber, density board, metal, glass, ceramic surface, belongs to the light solidifying coating technical field of composite materials.
Background technology
(UV) is coating material solidified for UV-light, and it is a kind of pollution-free, resource-saving, less energy-consumption, the safe and reliable friendly type coating of high-tech green environment, and its society and environmental benefit are huge; This product meets world's material technology trend, is coating circle new growth point, and the huge fund research and development are just competitively thrown in countries in the world.Now, on the occasion of advocate energetically because of the scarcity of China's energy, resource make up Sustainable development, conservation-minded society when, UV is coating material solidified has applied significance.The coating material solidified output of whole world UV was about 300,000 tons in 2005, and wherein Chinese about 100,000 tons, and annual with the speed increment more than 25%.In China, surpass the coating material solidified application that is used for the floor of UV of 70% sales volume, and also there are many problems in the wear resistance of current UV curing Floor paint.Study a kind of ultraviolet-curing paint that is applied to surface such as timber, density board, pottery, be the target of domestic and international coating circle pursuit with the wear resistance on surfaces such as comprehensive raising timber, density board, pottery always.The present invention mainly selects special wear-resisting crystal whisker materials for use, is equipped with photosensitive oligomer and filler etc. and has prepared the high-performance abrasion-proof ultraviolet-curing paint.
Summary of the invention
The purpose of this invention is to provide a kind of crystal whisker wear-resistant ultraviolet ray solidified paint and preparation method thereof, select that crystal whisker materials and the compound preparation of high performance photosensitive oligomer are a kind of to have better wear resistance, a more high-intensity whisker ultraviolet-curing paint for use.
Technical scheme of the present invention: a kind of crystal whisker wear-resistant ultraviolet ray solidified paint, (%) is as follows for the composition of its each component and weight percent:
Photosensitive oligomer 35~50
Reactive thinner 28~42
Light trigger 3~9
Whisker 5~18
Filler 3~16
Auxiliary agent 1~1.5
Described photosensitive oligomer is one or more in epoxy acrylic oligoesters, urethane acrylate quasi-oligomer, the polyester acrylic oligoesters; Described reactive thinner is in tripropylene glycol diacrylate, Viscoat 295,1,6 hexanediol diacrylate, pentaerythritol triacrylate, neopentylglycol diacrylate, the Isooctyl acrylate monomer two kinds or several; Described light trigger is benzophenones/amines system, benzil two ketals, Benzoin ethyl ether, 1-hydroxyl-phenylcyclohexane ethyl ketone, α, one or more in alpha-alpha-dimethyl-α hydroxy acetophenone, the thioxanthones; Described whisker is a kind of in calcium carbonate crystal whisker, potassium titanate crystal whisker, the ZnOw, and diameter range is 0.5~2 μ m, and length range is 20~40 μ m, carries out the surface modification treatment mistake by silane coupling agent or titanate coupling agent; Described filler is one or more in hollow glass microbead, silicon-dioxide, the elastic particle; Described auxiliary agent comprises wetting dispersing agent, anti-settling agent, flow agent and defoamer.Wetting dispersing agent is the derivatives class of polymer unsaturated polyester carboxylic-acid or poly carboxylic acid/amine; Anti-settling agent is organobentonite class or polyethylene wax; Flow agent is silicone based or polyacrylate(s); Defoamer is silicone based.
The preparation method of crystal whisker wear-resistant ultraviolet ray solidified paint of the present invention: by the composition and the weight percent of above-mentioned each component, reactive thinner, the wetting dispersing agent that adds in the component by proportioning in mixing tank mixes earlier, add gradually while stirring through surface-treated whisker, add filler, high speed dispersion is even, add anti-settling agent, flow agent and defoamer in photosensitive oligomer, the auxiliary agent then, adding light trigger again continues to mix, homodisperse, packing promptly makes crystal whisker wear-resistant ultraviolet ray solidified paint.
Beneficial effect of the present invention: the coating performance excellence that crystal whisker wear-resistant ultraviolet ray solidified paint of the present invention forms at timber, density board, metal, glass, ceramic surface, toughening effect is obvious, the wear resisting property of filming is greatly improved, its wear resistance can reach 0.005~0.02g/ (500r, 750g).Crystal whisker wear-resistant ultraviolet ray solidified paint of the present invention does not add organic solvent, helps environmental protection, and easy construction, has tangible environmental benefit, social benefit and economic benefit.
