Abstract

The invention discloses antibacterial polyurethane wood floor paint which comprises two parts: a hydroxyl group component A and a NCO component B. The antibiotic polyurethane wood floor paint is characterized in that the hydroxyl group component A is prepared by mixing and dispersing coconut oil alkyd resin, castor oil alkyd resin, cyclohexanone, n-butyl acetate, dimethylbenzene, antimicrobial, foam killer, flatting agent and drier at high speed; the NOC component B is obtained by evenly mixing and stirring dimethylbenzene, n-butyl acetate, toluene di-isocyanate and trimethylolpropane copolymer solution and preserving heat for 1h; and the weight proportion of the A component and the B component is 1:0.8-1.2. Aiming at overcoming the defects existing in the prior art, the invention provides the polyurethane wood floor paint which has excellent antibacterial performance, good application property and low hazardous substance content and has a paint coat with good wear resistance, shock resistance and adhesive force.

Description

technical field [0001] The invention relates to an antibacterial polyurethane wood floor paint, which belongs to the paint manufacturing industry. Background technique [0002] Polyurethane coating is a kind of coating with excellent comprehensive performance, which is widely used in wood decoration and wooden floor. Since wooden furniture or wooden floors will parasitize many harmful bacteria on their surfaces during the process of manufacture and use, in order to keep the surface of the products hygienic, external measures are usually taken, such as spraying medicines, wiping medicines, etc. Its disadvantages are easy loss of medicine, easy regeneration of bacteria, short antibacterial time, low antibacterial efficiency and high cost. Due to technical reasons, the existing polyurethane coating has no antibacterial function in the paint film, which is not conducive to the health of the home environment. [0003] Therefore existing polyurethane paint remains to be further ...
