Description
Technical field
The present invention relates to a kind of coating composition, more particularly to a kind of a kind of low gas for wooden articles external coating
Taste height resists soft scratch clear finish.
Background technology
It is used for the polyurethane paint of woodenware external coating in the market, generally includes two-component, respectively mian paint and solidification
Agent, is mixed when using according to predetermined proportioning, then adds appropriate diluent, is stirred evenly and be can be carried out brushing, constructs, company's operation
Simplicity, cost is also more economical with price.Then, such coating has that antifraying property is poor, anti-wear performance is low and construction surface light
Damp degree, the shortcomings of transparency is inadequate.
Present wooden articles incrustation is all to reinforce agent using common anti scuffing clear finish to be produced with clear finish,
Furniture residual smell is big after the completion of application, hardness is low, surface is easily scratched, and because mian paint is big admittedly containing low, resin residue smell, causes paint
Film is not plentiful enough to resist the shortcomings of soft scratch is poor, causes many disadvantages and problem during real onsite application to exist.
Therefore, how to improve existing wooden articles clear finish formula composition and technique be current art technical staff after
The continuous technical barrier solved.
The content of the invention
It is big in order to solve clear finish smell in the prior art, resist the problems of soft scratch resistance difference, the purpose of the present invention
It is to provide a kind of low smell height and resists soft scratch clear finish, the main castor oil modified alkyd resin of low taste using in formula is wiped with anti-
Hinder powder collocation so that paint film odor residual is extremely low；Have hardness high simultaneously, it is soft scratch resistance good to resist, levelling and richness are good etc.
Characteristic.
Another object of the present invention is to provide a kind of preparation method of the above-mentioned low anti-soft scratch clear finish of smell height.
A kind of low smell height of the present invention resists soft scratch clear finish, and the paint adds anti-wiping by the castor oil modified alkyd resin of low taste
Hinder powder and polyurethane lacquer host, curing agent, diluent composition is made, construction proportioning is：Host：Curing agent：Diluent=1：
0.5：0.5.
The anti-soft scratch clear finish host component proportion of low smell height is：
Wherein, hydroxy acrylic acid fat resin is Bayer Desmophen A450；Defoamer is Bi Ke chemistry BYK066N brokenly bubbles
Polymer poly siloxane solution；Dispersant is the EFKA4010 modified polyurethane solution of EFKA, and flatting silica creates Degussa to win
OK520 flatting silicas, anti-settling agent be Supreme Being Si Balong 6900-X-20 polyamide wax pulps；Anti scuffing powder is silicon than section mining industry
706 high-purity quartz powder.
The curing agent component is matched：
Toluene di-isocyanate(TDI) (TDI) tripolymer 35.0%；
Toluene di-isocyanate(TDI) (TDI)-trimethylolpropane addition product 40.0%；
Butyl acetate 25.0%；
The thinner composition is matched：
Butyl acetate 35.0~60.0%；
Propylene glycol methyl ether acetate 25.0~45.0%；
Dimethylbenzene 0~15.0%.
In addition, the present invention also provides a kind of preparation method of the anti-soft scratch clear finish of low smell height, including step：
1) paint host is prepared：Component is weighed by weight percentage, resin solvent is put into, middling speed is disperseed, and input function is helped
Agent, it is scattered at a high speed, put into delustering agent respectively successively, anti-settling agent, anti scuffing powder is then scattered at a high speed, obtains host finished product；
2) curing agent is prepared；Weigh component by weight percentage, put into curing agent successively, solvent, then middling speed disperse, obtain
Curing agent finished product
3) diluent is prepared：Component is weighed by weight percentage, solvent is put into, and then middling speed is disperseed, and obtains diluent finished product.
The advantageous effects that the present invention can be reached using above-mentioned technical solution are：
1) product of the present invention is covered with paint, lacquer, colour wash, etc. for woodenware product surface, and application mode is using spraying.
2) product of the present invention has smell residual extremely low；Have hardness high simultaneously, resist soft scratch resistance good, levelling and richness
Good the features such as, and there is lower smell, preferably anti-soft scratch, more preferable richness compared to clear finish used in the market
The characteristics of Deng protruding.
