The present invention relates to a kind of woodwork coating, particularly a kind of colored polyurethane antibacterial wooden article coating.
Background technology
Wood product surfaces such as wooden furniture, timber floor exist harmful bacterium at present, in order to keep the health of product surface, adopt outside measure usually, as spraying medicine, medicine wiping etc.Its defective is that medicine easily runs off, and bacterium easily regenerates, and antibiotic timeliness is short, and antimicrobial efficiency is low, the cost height.
Summary of the invention
The objective of the invention is to solve the existing problem of woodwork coating in the prior art, a kind of application of woodworks such as wooden furniture, timber floor and colored polyurethane antibacterial wooden article coating of decoration design for residence of can be used for is provided.The present invention designs a kind of colored polyurethane (PU polyester) antibacterial wooden article coating, it is characterized in that: constitute by A, B two components,
The A component is that following constituent and weight percent are formed:
The affixture of tolylene diisocyanate (TDI) and TriMethylolPropane(TMP) or the tripolymer of TDI or their mixture 25%~65%, N-BUTYL ACETATE or vinyl acetic monomer, xylene solvent or their mixture 35%~75%, the B component is that following constituent and weight percent are formed: Synolac or modified alkyd resin, or their mixture 49.88%~69.88%, N-BUTYL ACETATE or vinyl acetic monomer, xylene solvent or their mixture 10.19%~30.19%, defoamer 0.16%~0.36%, flow agent 0.20%~0.50%, pigment or dyestuff 3.50%~30.50%, antiseptic-germicide 0.10%~5.0%, dispersion agent 0.10%~0.30%, anti-settling agent 0.04%~1.0%, anti-yellowing additive 0.79%~0.99%, matting agent 0%~12.50%, first component and component B are in 0.3~1: 1 ratio is mixed.Defoamer is CFC-151, BYK 066, moral modest 5100 or their mixture.Flow agent is KEPER-150, BYK 310, HX-3130 or their mixture.Pigment or dyestuff are titanium dioxide, permanent yellow, light-resistant dye or their mixture.Antiseptic-germicide is mineral-type nano titania antiseptic-germicide, organic class isothiazolinone antiseptic-germicide or their mixture.Dispersion agent is KEPER-602, BYK-110 or their mixture.Anti-settling agent is 6901-20X, BYK 410, efka-, 4500 or their mixture.Anti-yellowing additive is KH-10,1130 or their mixture.Matting agent is ED30, mute light powder or their mixture.Advantage of the present invention is to kill the bacterium of wood product surfaces such as wooden furniture, timber floor.
Below in conjunction with embodiment the present invention is elaborated,
Embodiment
Can add proper amount of diluting during construction as the case may be and regulate viscosity.
The present invention mainly utilizes filmogen (Synolac, modified alkyd resin or cellulose nitrate ester etc.) in the prescription, antiseptic-germicide, matting agent, N-BUTYL ACETATE, pigment (dyestuff), flow agent, defoamer etc., in the coating process of woodworks such as wooden furniture, timber floor, form antibacterial film, kill the bacterium that grows on its surface thereby press down.Have advantages such as antimicrobial efficiency height, decorative effect are good, easy construction, can be used as the application and the decoration design for residence of modern wooden furniture.
After testing, antimicrobial efficiency is 99.9%.
After testing, harmful substance contents is as follows:
Volatile organic compounds (VOC) 648g/L
Benzene does not detect
Toluene and dimethylbenzene summation 28.5%
Free toluene diisocyanate 0.5%
After testing, main quality and technical index is as follows:
Appearance of film surfacing, smooth
