Abstract
The invention relates to a water-based primer, in particular to a water-based conglutination primer for solid-wood products and a preparation method thereof. The water-based conglutination primer is prepared by mixing the following raw materials in percentage by weight: 30 to 65 percent of polyacrylic emulsion, 30 to 65 percent of water, 2 to 5 percent of alcohols-ethers solvent, 1 to 3 percent of thickening agent and 0.5 to 1 percent of defoaming agent, wherein a Tg value of the polyacrylic emulsion is more than or equal to 30 DEG C and less than or equal to 70 DEG C. The water-based conglutination primer is first coated and brushed on the solid-wood products, can permeate through wood fibers and form a continuous dense paint film at a position 1 to 2 mm away from the surface of wood to play a role in sealing, also can completely expand and harden splinters of the wood and the wood fibers on the surface of the wood so as to be favorable for smoothly grinding the wood thorns and the wood fibers, and can effectively prevent the infiltration of water content from causing the expansion of the wood in re-construction due to the continuous dense film below the surface of the wood.
Description
Technical field
The present invention relates to a kind of aqueous priming paint, specifically a kind of water-based conglutination primer for solid-wood products and preparation method thereof.
Background technology
The solid wood woodwork is in the Water-borne modification coating process, and solid wood has been prone to wood thorn, sends out problem such as rise.Wood products and antique coloring woodwork all are to adopt solvent reducible coatings traditionally, and its production technology generally adopts benzene series thing, ketone, pure ethers, ester class to make solvent, and nitro or urethane are as main filmogen, and part filler and auxiliary agent are formed.There has not been perverse and the wooden footpath of a wood problem that rises in treatment agent at the bottom of adopting the timber that this method produces, but owing to the above-mentioned a large amount of deleterious organic solvents of employing, and workmen and product end user's healthy and environment has all been brought bigger harm.Therefore in order to adapt to environmental requirement, the protection people's is healthy, and people begin one's study and develop various aqueous, environmental protective coating now.The aquatic lacquer of being sold in the market is on the facing plate, to construct basically, grows dim etc. unusually and high-grade solid wood true qualities and solid wood are modelled after an antique owing to there have been problems such as perverse, the muscle that rises of wood, cause the paint film unfairness, wipe look, so does not obtain popularization basically.Therefore inventing the solid priming paint of water-base cement that a kind of wood products uses is highly profitable.
Summary of the invention
The object of the invention is exactly the defective to existing water-borne coatings; A kind of water-based conglutination primer for solid-wood products and preparation method thereof is provided, and it can make aqueous woodware paint be applied to high-grade solid wood better and the high-grade solid wood of solution is imitated when accounting for the wiping look because perverse white point grow diming phenomenon that rises and caused after polishing off of wood.
Technical scheme of the present invention is achieved in that it is mixed by following raw materials by weight: ACRYLIC EMULSION 30%～65%, water 30%～65%, pure ether solvent 2%～5%, thickening material 1%～3%, skimmer 1%, wherein the Tg value of ACRYLIC EMULSION is 30 a ℃≤Tg value≤70 ℃.
The present invention's technical scheme preferably is that it is mixed by following raw materials by weight: ACRYLIC EMULSION 30%～65%, water 30%～65%, pure ether solvent 2%～5%, thickening material 1%～3%, skimmer 1%, wetting agent 0.1%～0.5%, wherein the Tg value of ACRYLIC EMULSION is 30 a ℃≤Tg value≤70 ℃.
The better technical scheme of the present invention is that it is mixed by following raw materials by weight: ACRYLIC EMULSION 50%, water 40.5%, pure ether solvent 5%, thickening material 3%, skimmer 1%, wetting agent 0.5%, wherein the Tg value of ACRYLIC EMULSION is 30 a ℃≤Tg value≤70 ℃.The Tg value is less than 30 ℃, and the paint film of formation is soft, and playing wooden perverse phenomenon can't overcome; The Tg value is greater than 30 ℃, and the paint film of formation is harder, can not cause the white point grow diming phenomenon after the polishing.
The solid content of described ACRYLIC EMULSION is 30%～45%, and the pH value is 7～9.The preferred ACI-2602 that adopts safe and sound chemistry.
Described pure ether solvent is selected from one or more in organic alcohol or the organic ether, one or more in preferred gylcol ether series, Ucar 35 ethers series, Diethylene Glycol ethers series, dipropylene glycol ethers series, triethylene glycol ethers series, the tripropylene glycol ethers series etc.In general, faster dried good more.
Described thickening material is oleic series thickening material or urethane series thickening material.Preferred employing trade names are RM-2020 or the ASE-60 of Tao Shi.
Described skimmer is mineral oil defoaming agent or polysiloxane-polyether copolymer defoamer.The preferred BYK-094 that adopts aerochemical DF-210 or BYK company.
Described wetting agent is a polysiloxane-polyether copolymer.The TEGO 245 of preferred TEGO company.
Preparing method of the present invention comprises the steps:
1, at first ACRYLIC EMULSION and water are under agitation mixed, add skimmer, wetting agent again.
2, high speed stirs the solvent that adds pure ethers down at a slow speed.
3, adding thickening material at a slow speed mixes.
Method of use of the present invention can dip-coating, brushing, spraying.Also can add mill base, look essence comes the timber processing of changing colour.
Organic solvent proportion of the present invention is less than 5%, and is harmless relatively hypotoxicity alcohol ethers, environmental protection in the pink of condition.This product uses when being used for ground and handling for the first time in coating process.This product is brushing earlier on wood products; Can infiltrate through in the lumber fibre,, play sealing process forming fine and close continuously paint film apart from wood surface 1-2mm place; And can make the wood thorn of timber and the abundant bulging of xylon and the hardening on surface; Be beneficial to and polish flat, because the film of continuous densification is arranged below the wood surface, following the oozing of moisture in can effectively preventing to construct once more and the problem that causes timber to be sent out rising.
The present invention is used for the solid priming paint of solid wood water-base cement, possesses traditional timber seal coat effect, and has following advantage:
1, environment-friendly tasteless does not have injury to the constructor.
2, the perviousness to solid wood is very strong, can infiltrate third one in timber fast, and loose timber is reinforced.
3, fast dry, polishing easily.
4, the water-miscible paint of constructing again after this product polishing, perverse no longer the sending out with conduit of solid wood wood risen, and this does not exist perverse problem that rises of wood, painted white point gas and the grow diming phenomenon of not occurring yet to wipe Gree.
5, the adaptation of product is wide, can be used for the substrate treatment of all solid woods, also can be used for the substrate treatment on the facing plate simultaneously.Have rapid drying equally, prevent to wipe unusual that look grows dim.
6, production technique is simple, need not high-shear and disperses, and saves man-hour and energy consumption.
7, can construct in many ways, spraying, dip-coating, showering, obliterating, roller coating etc., tolerance is big.
