Description
Technical field
The present invention relates to water paint fields, disclose a kind of for the Environmental Protective Water-paint of wood furniture and preparation side
Method.
Background technique
In the source of atmospheric pollution of people's common concern, volatile organic matter (VOC) is one of significant contributor.It is existing
Oil paint makes one of VOC primary discharge source.The volatilization of the high VOC of organic solvent content therein is big.Especially as indoor dress
Wooden furniture is adornd, carries out coating using a large amount of coating.Therefore the aqueous wooden ware coatings for furniture for developing environmental protection is that VOC is avoided to generate
Most effective approach.
Water paint is either produced, is stored, construction compared to oil paint, or is applied to indoor furniture, is all reduced
Pollution of the VOC to environment.Water paint includes water soluble paint, water-reducible coating, water-dispersible paint (latex paint) 3
Kind.Using water-soluble resin as film forming matter, using polyvinyl alcohol and its various modifiers as representative, in addition to this also water soluble paint is
There are water-soluble alkyd resin, water-soluble epoxy resin and inorganic polymer water-base resin etc..
Water-borne wood coating mainly has acrylic acid and polyurethane system at present.Acrylic acid aqueous wooden ware as main component
Paint, is mainly characterized by that adhesive force is good, will not deepen the color of woodenware；Polyurethane aqueous paint, comprehensive performance is superior, richness
Height, hardness of paint film is high, and wear-resisting property is even more than oil paint, all has a clear superiority in terms of service life, color conditioning；Acrylic acid
With the synthetic aqueous woodware paint as main component of polyurethane, feature increases other than the characteristics of adhering to acrylic paint
Wear-resisting and strong chemical resistance feature.The research and application of novel aqueous woodwork coating are still current hot subject.
Chinese invention patent application number 201410406711.9 discloses a kind of water paint that indoor woodenware uses, according to
Parts by weight, ingredient include 20 ~ 30 parts of silicone acrylic emulsion, 5 ~ 20 parts of color filters, 5 ~ 10 parts of modifying agent, 10 ~ 30 parts of compounded mix,
40 ~ 50 parts of water, wherein color filters include 2 ~ 8 parts of low arsenic iron oxide, 5 ~ 11 parts of iron oxide red, 1 ~ 2 part of toluene, compounded mix packet
Include 1 ~ 5 part of silica solution, 5 ~ 15 parts of calcium carbonate, 1 ~ 5 part of scratch resistance wax assistant.The advantages of invention, is low arsenic iron oxide, oxidation
Iron oxide red, toluene are color forming property as paratonere, the even property of color is preferable, and silicone acrylic emulsion can effectively solve water paint to a certain extent
Anticorrosion；Modifying agent makes curing rate also be improved；The effect of indoor woodenware painting is preferable, extends using the longevity
Life is suitable for promoting.
Chinese invention patent application number 201710022007.7 discloses a kind of woodenware renovation water paint and its preparation
Method, wherein each component raw material of the woodenware renovation with water paint comprising following parts by weight: self-crosslinking aqueous resin 70 ~ 90
Part；3 ~ 5 parts of coalescing agent；0.1 ~ 0.3 part of wetting agent；0.1 ~ 0.5 part of defoaming agent；0.2 ~ 0.6 part of thickener；Grinding auxiliary agent 1 ~ 3
Part；0.1 ~ 2.0 part of adhesion promoter；0.1 ~ 0.3 part of fungicide；1.2 ~ 12.4 parts of deionized water.It is aqueous described in the invention
Coating has well solved current aqueous woodware paint coating and the bad problem of oil paint adhesive force, while woodenware renovation is used
Water paint has very high dry and wet film transparency, good grinability and faster rate of drying.
According to above-mentioned, in the water paint of woodenware in existing scheme, since acrylic acid and aqueous polyurethane itself lack
It falls into, the coating hardness that is formed for wood furniture and wears no resistance, and is poor water resistance, easy to crack, it usually needs inorganic fills out is added
Expect to improve the hardness and water resistance of coating, and in practice, since inorganic filler and coating matrix dispersion compatibility are poor, shadow
The film-formation result for having rung coating causes coating easy to crack.
Summary of the invention
The wider water paint for wood furniture is applied at present, there are coating hardness and is worn no resistance, poor water resistance,
Defect easy to crack, and usually by be added inorganic filler method, due to inorganic filler and coating matrix dispersion compatibility compared with
Difference affects the film-formation result of coating, causes coating to have the defects that wear no resistance, is easy to crack.
To solve the above problems, the invention adopts the following technical scheme:
