[0040] 1. Preparation of Antibacterial Sustained Release Capsules:

[0041] Get nano-silver antibacterial agent, pulverize and cross 80 mesh sieves, place the material chamber of fluidized bed coating granulator, the aqueous solution of 5%wt polyvinyl alcohol is binder, start fluidized bed coating granulator to obtain capsule core.

[0042] The capsule core is placed in a fluidized bed coating granulator for coating, and the coating liquid is an aqueous solution of 5%wt acrylic resin. Dry at 40° C. for 24 hours to obtain dry antibacterial sustained-release capsules. Wherein the formula ratio of nano-silver antibacterial agent, polyvinyl alcohol and acrylic resin is shown in Table 2.

[0043] 2. Preparation of water-based wood paint:

[0044] Add water and acrylic acid emulsion into the stirred tank, stir at a speed of 1000-1200 rpm, add polyethylene oxide, propylene glycol butyl ether, diethylene glycol butyl ether and zinc stearate abrasive, and stir evenly. Reduce the st...

Abstract

The invention discloses a waterborne carpentry paint including an acrylic emulsion, antibacterial sustained-release capsules, and an auxiliary agent acceptable in the waterborne carpentry paint. An antibacterial agent is externally coated with a layer of sustained-release material, to achieve a purpose of slow release of the antibacterial agent and ultimately meet the durable antibacterial insect-prevention effects. The invention aims to provide the durable antibacterial insect-prevention waterborne carpentry paint.

Description

technical field [0001] The invention relates to the field of fine chemicals, more specifically, it relates to a water-based wood varnish. Background technique [0002] Today, with increasing emphasis on paint safety and environmental protection indicators, water-based wood paints are gradually accepted by the market because of their low-hazard and low-pollution characteristics. But water-based wood lacquers also have many disadvantages at present, one of which is that the insect-proof performance of water-based wood lacquers is not as good as that of oil-based wood lacquers because of its low toxicity. [0003] The Chinese patent with authorized notification number CN100387666C discloses a nano-silver antibacterial water-based wood varnish and a preparation method thereof, which contains a nano-silver antibacterial agent. Although this kind of water-based wood lacquer can achieve the effect of bactericidal and insect-proof, silver ions are thermodynamically unstable, and mo...
