Abstract

The invention involves a kind of polyurethane (the PU polyester) the antibacterial wooden article varnish (lusterless, bright), its characteristic lies in: By A, the B two components constitutions, the A component is composed for following constituent and the per cent by weight: The toluene two isocyanogens diethylene glycol dinitrate (TDI) and three methylol propane addition compound either TDI three is concrete or their mixture 25%~65%, acetic acid Ding Zhihuo ethyl acetate either toluene or their mixture 35%~75%, B component for following constituent and per cent by weight composition: The alkyd resin either the modified alkyd resin or their mixture 55.65%~75.55%, the cutyl acetate either the cutyl acetate or the xylene or their mixture 7.86%~9.86%, the defoamer 0.16%~0.36%, flows the even medicinal preparation 0.20%~0.40%, the deadening agent 0%~12.50%, antibiotics 0.10%~5.0%, the dispersing agent 0.10%~0.30%, guards against sinks medicinal preparation 0.04%~1.0%, the nitric acid cellulose ester 0%~15.57%, armor component and second grade component according to 0.3~1: 1 proportion mix construction. The invention merit is can kill extinguishes wooden woodware surface the and so on the furniture, wood floor bacterium.

Description

technical field [0001] The invention relates to a woodware coating, in particular to a polyurethane PU polyester antibacterial woodware varnish. Background technique [0002] At present, there are harmful bacteria on the surface of wooden products such as wooden furniture and wooden floors. The disadvantage is that the drug is easily lost, the bacteria are easily regenerated, the antibacterial time is short, the antibacterial efficiency is low, and the cost is high. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the existing problems of wood products and woodware coatings such as wooden furniture and wooden floors in the prior art, and to provide a solvent-based antibacterial woodware that can be used for the coating of wood products such as wooden furniture and wooden floors and home decoration and decoration coating. The invention designs a polyurethane PU polyester antibacterial wood varnish, which is characterized in that it is com...
