Abstract

The present invention relates to the preparation method of a kind of wood substrates coating.The present invention is with acrylate, modified vinyl chloride-vinyl acetate resin and celluosic resin as matrix resin, with a certain amount of acrylate monomer and light trigger for mainly comprising, under organic solvent system, dissolve a kind of wood substrates coating prepared by reaction, inject row solidification by ultraviolet lighting.Cheaper starting materials of the present invention is easy to get, and preparation method is simple, and gained coating system stability is high, it is easy to stores and transports.The most compared with the prior art, the coating hardness prepared by this method and scraping and wiping resistance performance are obviously improved, thus improve the protected effect to wood substrates.

Description

A kind of preparation method of wood substrates coating
Technical field
The present invention relates to a kind of chemistry painting industry preparation field, a kind of use on wood substrates can use light The preparation method for coating of solidification.
Background technology
Timber plays in key player, especially furnishing fields in the modern life always.Along with people's living standard Raising, interior decoration decoration has become the important component part of quality of the life, and the product of wood substrates is as main force's group Become to have bigger development future.But the ornament of existing wood substrates still has in terms of moistureproof anti-deformation and Wear-resistant scratch-resistant wiping All deficiencies, the most usually can protect its ornamental continuity at the coating that its surface-coated is relevant.But see at present, market On wood substrates coating generally exist adhesive force typically, the defect that the most wear-resisting and surface smoothness is inadequate, thus cause timber The ornament service life of substrate is long, decorative effect weakens rapidly problem and cause variety of problems.And photocureable coating tool Have that the suitability is wide, normal temperature cure, wear-resisting and fineness advantages of higher, have been widely used the necks such as chemical industry, machinery, furniture, ink Territory.Meanwhile, by the further improvement to photocureable coating, find this coating and there is the advantage such as high rigidity, high scratch resistance, The deficiency existing for wood substrates coating can be improved targetedly, thus obtain market accreditation.
The present invention is a kind of coating for wood substrates, uses ultraviolet lighting to inject row solidification.With cheap and easy to get Acrylate, modified vinyl chloride-vinyl acetate resin, celluosic resin and a certain amount of acrylate monomer, light trigger for mainly comprising, The coating being prepared as by simple reactor hybrid mode can make surface of wooden substrate possess higher intensity and scratch-resistant Performance.Grant number is that the patent of CN102643600B mentions a kind of light solidifying paint composition, and by actual verification, it is many Scheme can not really realize and performance on wood substrates is poor.Wood substrates photocuring is solved herein for property All deficiencies that coating should possess, possess higher marketing prospect.
Summary of the invention
The use acrylate that the invention aims to all deficiencies of more than solution and provide, modified chlorine vinegar tree Fat, celluosic resin and acrylate monomer, light trigger are the preparation of a kind of wood substrates coating mainly comprising preparation Method.
In order to achieve the above object, the invention provides the preparation method of a kind of wood substrates coating, including operation such as Under:
1) acrylate of 10-40kg, 5-15kg modification vinyl chloride-vinyl acetate resin and the celluosic resin of 3-8kg are taken, by several Resin has taken standby;
2) in reactor, add organic solvent 40-90kg, be heated to 40-80 DEG C, the resin of step 1) is put into reactor In, open stirring 1-2h, make the resin in reactor all dissolve;
3) in reactor, add acrylate monomer 25-35kg, add light trigger 2-7kg, add auxiliary agent 0.5-simultaneously 1.5kg, continues stirring 0.5-1h and makes system be uniformly dispersed;
4) after system is uniform, stop stirring, make temperature of reaction kettle naturally cool to room temperature, filtration product, obtain final painting Material product.
Wherein, described acrylate refer to molecular weight 150,000-25 ten thousand methylmethacrylate copolymer, institute The modified vinyl chloride-vinyl acetate resin stated refer to molecular weight 100,000-30 ten thousand modified ternary carboxyl vinyl chloride vinyl acetate resin, described Celluosic resin refers to one or both in cellulose acetate propionate resin, acetylbutyrylcellulose resin, and described is organic Solvent is the one in normal propyl alcohol, isopropanol, n-butyl alcohol, ethyl acetate, n-butyl acetate, propylene glycol monomethyl ether, propylene-glycol ethyl ether Or multiple, described acrylate monomer be trimethylolpropane trimethacrylate, trimethylol-propane trimethacrylate, Two or more in ethoxyquin trimethylolpropane trimethacrylate, the third oxidation trimethylolpropane trimethacrylate, described Light trigger be benzophenone, described auxiliary agent is one or more in defoamer, cross-linking agent, levelling agent.
The coating that the method produces applies on the product of wood substrate, it is possible to its hardness of bigger improvement and scratch resistance Can, possess preferable marketing prospect.
Detailed description of the invention
Embodiment 1
1) take the acrylate of 35kg, 12kg modification vinyl chloride-vinyl acetate resin and the celluosic resin of 6kg, several resins are taken Standby;
2) in reactor, add organic solvent 60kg, be heated to 80 DEG C, the resin of step 1) is put in reactor, open Stirring 1h, makes the resin in reactor all dissolve;
3) in reactor, add acrylate monomer 30kg, add light trigger 4kg, add auxiliary agent 0.8kg simultaneously, continue Stirring 0.5h makes system be uniformly dispersed;
4) after system is uniform, stop stirring, make temperature of reaction kettle naturally cool to room temperature, filtration product, obtain final painting Material product.
Embodiment 2
1) take the acrylate of 40kg, 13kg modification vinyl chloride-vinyl acetate resin and the celluosic resin of 7kg, several resins are taken Standby;
2) in reactor, add organic solvent 70kg, be heated to 70 DEG C, the resin of step 1) is put in reactor, open Stirring 1.5h, makes the resin in reactor all dissolve;
3) in reactor, add acrylate monomer 33kg, add light trigger 5kg, add auxiliary agent 1kg simultaneously, continue to stir Mixing 0.6h makes system be uniformly dispersed;
