Description
Technical field
The present invention relates to paint field, be specifically related to the preparation of a kind of quick-dry type aqueous dual-component acrylic acid dumb light woodcare paint
Method.
Background technology
Woodcare paint is a kind of guarantor being used in the places such as timber, plank, density board, furniture, kitchen cabinet, desk, paper panel
Protect, decorative coating, in China, the production of woodcare paint, usage amount are only second to industrial paint, and annual consumption alreadys more than 400,000 tons.
The development experience of woodcare paint several stages, the earliest be the Resina Toxicodendri verniciflui (being again state's paint, lacquer) of one pack system, be with sky
Right Oleum Verniciae fordii, oleum lini are main raw material(s).Later along with development, the appearance of high molecular polymer of chemical industry, woodcare paint
Industry occurs in that alkyd paints, is with the alkyd ready mixed paint of one pack system, enamel paint as major product during beginning.To the sixties,
China introduces technology, and successfully have developed solvent-type double-component polyurethane formaldehyde alkyd woodenware paint.This with polyurethane resin for solidification
Agent, the solvent-type double-component woodcare paint being paint base resin with short oil alkyd resin, adhesive force is strong, good hand touch, hardness are high, has very
Decorative effect high, good, meets the demand of the GOOD TASTE life of people.But, this solvent-type double-component polyurethane alkyd
Woodcare paint, with organic solvent as diluent, affects environment.Simultaneously as curable urethane resin agent is with toluene di-isocyanate(TDI)
(TDI) it is raw material, wherein can remain free TDI, and the TDI being discharged into air belongs to toxic chemical, has a strong impact on, threaten
Healthy to people.At present, although industry again and again require reduce free TDI content, reduce consumption of organic solvent, but by
Difficulty in technical elements, it is difficult to thoroughly eliminate the free TDI in polyurethane curing agent.So, coating industry is at the seventies
Woodcare paint research direction has been turned to environmental protection, healthy water paint field.
Aqueous woodware paint at China's research ratio earlier, but until 80 years, just has kind few in number to come out, its
In have one pack system, also have bi-component.Aqueous woodware paint has three big technical bottlenecks have impact on the popularization of aqueous woodware paint and make
With: one is that hardness is low；Two is that rate of drying is slow；Three is that richness can not meet people's requirement.Self-crosslinking single component employs suitable
The self-crosslinking technology of degree, the hardness of paint film, richness relatively volatile dry type one pack system increases, but hardness, richness are still
So do not reach the index of bicomponent system, requirement.Bi-component be with the reactable group on polyurethane curing agent molecular structure-
On NCO and component B (paint base resin) molecular structure, reactable group-OH (hydroxyl) carries out cross-linking reaction, so bi-component water
The property hardness of woodcare paint, richness can meet the market demand.But, owing to all taking with water as solvent, diluent, also have
The organic cosolvent of the high boiling point Organic Alcohol ethers added in paint, causes drying varniss speed relatively slow, particularly in cold
In winter, have a strong impact on the normal construction of woodcare paint especially.
Low luster coating color and luster is soft, flat appearance, can cover up coating surface defect to a certain extent, and high-gloss paint pair
Eye has certain stimulation, allows the vision of people the most tired for a long time.Low luster coating overcomes this shortcoming of high-gloss paint, symbol
Close the aesthetic requirement of people.The pursuit that high-quality is lived is made the demand of aqueous low luster coating increasing by people, exploitation height
The water paint of performance low cost becomes study hotspot.
At present, hardness aspect is best with dual-component aqueous polyurethane woodcare paint, i.e. with the water containing crosslinkable groups-NCO
Property polyurethane resin is firming agent, with aqueous hydroxy acryl acid resin or aqueous hydroxyl group containing polyester resin for paint base resin.Paint
The solidification of film carries out cross-linking reaction realization by NCO with activity hydroxy.
But, due to technicals, can reactive hydroxyl groups (-OH) on current second component (paint base resin) molecular structure
For secondary hydroxyl, have impact on the solidification crosslinking of aqueous woodware paint, rate of drying.
Summary of the invention
The technical problem to be solved is the deficiency overcoming the rate of drying of prior art aqueous woodware paint slow, carries
Preparation method for a kind of new quick-dry type aqueous dual-component acrylic acid dumb light woodcare paint.
For solving above-mentioned technical problem, the present invention uses following technological means:
The preparation method of a kind of quick-dry type aqueous dual-component acrylic acid dumb light woodcare paint, including first component and second component, first
