Description

Water-borne wood coating
Technical field
The invention belongs to technical field of coatings, is related to a kind of water-borne wood coating.
Background technology
In May, 2015, country put into effect most tight environmental law in history ---《Wood furniture manufacturing industry Air Pollutant Emission mark It is accurate》, wherein for the control requirement of wood furniture manufacturing industry Air Pollutant Emission, and entered July 1 the as defined in standard One stage.New standard provides that contained benzene particulate matter highest allows the prescribed limits of concentration of emission to be greatly reduced in wood furniture. If furniture enterprise is not transformed production line, still using oil paint, and without using the lower water of pollutant emission level Property paint, then hardly consistent with the requirement of new standard, ultimately result in commercially to sell its product.
The data that China Association of Coatings Industry announces show that Chinese application industry is every year to the volatile organic of air discharge Compound (VOC) total amount counts roughly 4,300,000 tons, and wherein oil paint accounting is about 98%, and water paint accounting is about 2%, it can be seen that, water The environment-friendly advantage of property paint is obvious.Further, country proposes that water paint will substitute comprehensively with requiring that oil changes water in the 2-3 years Solvent based coating.Shenzhen has put into effect to prohibit selling comprehensively in succession seriously endangers the solvent based coating of citizen's health.Believe, water-based ring Friendly coating has welcome its spring.Compared with oil paint, water paint is disperseed with water, the coating of dilution, and feature is environmental protection It is nontoxic, it is nonflammable, without the carcinogens such as benzaldehyde and heavy metal.However, existing water paint using aqueous polyurethane as Raw material is prepared, and such water paint still has the presence of the carcinogens such as formaldehyde.
Chinese patent (200710026888.6) discloses a kind of nano antibacterial water woodenware paint, different water-based with three kinds Ester-polyurethane resin emulsion, aqueous acrylic modified ester-polyurethane resin emulsion and nano modified acrylic resin emulsion are in varing proportions Mixture is prefabricated molten with organic expander soil as film forming matter, and nano composite inorganic antiseptic, the nano composite inorganic antiseptic Glue is carrier, includes Nano Silver, nano zine oxide, nano aluminium oxide, nano titanium oxide and nano silicon.The invention The coating VOC values being prepared are low, and resist blocking and that, damage resistant, anti-pollution, color inhibition and closure are good, but it adds inorganic receive Rice grain is more, and production cost is low, and poor with matrix resin emulsion compatibility, and stability is bad.
The content of the invention
The present invention proposes a kind of water-borne wood coating, and the coating antibiosis excellent performance, environment-protecting and non-poisonous, adhesive force is strong.
The technical proposal of the invention is realized in this way:
A kind of water-borne wood coating, according to the number of parts by weight, including following components:
40~60 parts of emulsion acrylic resin, 20~30 parts of aqueous alkide resin emulsion, titanium load silver-colored 3~6 parts of bactericide, 40~60 parts of 1~2 part of dispersant, 3~6 parts of levelling agent, 5~10 parts of thickener and deionized water, wherein, titanium loads silver-colored bactericide Mainly it is prepared by silver nitrate, inidum chloride and butter of tin.
Preferably, the preparation method of the silver-colored bactericide of the titanium load is:
In the water that silver nitrate is dissolved in, titanium sulfate solution is then added dropwise, after stirring, adds urea, is progressively warming up to 60 DEG C~80 DEG C are precipitated, and precipitation terminates laggard water-filling and washed, in 500 DEG C~600 DEG C calcinings after drying, you can obtain titanium load Silver-colored bactericide.
Further, the concentration of titanium sulfate solution is 50~80g/L.
Preferably, the emulsion acrylic resin is organosilicon modified crylic acid resin emulsion, epoxy-modified acrylic acid tree At least one of fat liquor, aromatic urethane emulsion acrylic resin.
Preferably, the dispersant is in for sldium lauryl sulfate, dioctyl succinate disulfonate acid and sodium glycocholate It is one or more kinds of.
Preferably, the levelling agent is dimethyl silicone polymer, organic silicon modified by polyether oxygen alkane and polyester resin change properties of organic silicon One or more in oxygen alkane.
Preferably, the thickener is bentonite and diatomite.
The preparation method of the water-borne wood coating of the present invention, comprises the following steps:
1) emulsion acrylic resin, aqueous alkide resin emulsion and the silver-colored bactericide of titanium load are weighed to be mixed evenly, is stirred It is 30~40min to mix the time, and discharging obtains mixture A;
2) dispersant is added in mixture A and is uniformly mixing to obtain mixture B;
3) levelling agent, thickener and deionized water are added in mixture B and stirred, cross screen filtration, i.e., Obtain water-borne wood coating.
Beneficial effects of the present invention:
1st, water-borne wood coating of the invention loads silver-colored bactericide from titanium and not only acts as bactericidal effect, even more important its There can also be decomposing formaldehyde function.4 are both greater than to the antibacterial value of staphylococcus aureus and Escherichia coli, antibiotic rate reaches 97.2%.Hardness is high, resistance to scratching, and content of formaldehyde is low (being less than 1.5ppm).
2nd, from emulsion acrylic resin and aqueous alkide resin emulsion as film forming matter, resistance tocrocking and resistance to is improved Acid-base property, additionally aid the silver-colored bactericide of titanium load and play its heat-proof quality.
