Abstract

The invention discloses a clear woodenware varnish, which comprises the following components in percentage by mass of 100 percent: 20-30% of soybean oil alkyd resin; 15-26% of lavender oil; oxidizing 10-15% of turpentine; 5-6% of wood wax; 3-5% of carnauba wax; 3-5% of rosin; 5-10% of copal; 5-15% of photocatalyst; 0.5 to 1.0 percent of dispersant; 1-5% of amphoteric surfactant; 2.0 to 4.0 percent of glycol; 0.2 to 0.5 percent of defoaming agent; 0.2 to 0.5 percent of preservative; 3.0 to 4.5 percent of film forming additive; 0.1 to 0.3 percent of multifunctional additive. Under the action of the amphoteric surfactant and the coordination of other related auxiliaries, the woodware varnish disclosed by the invention is more environment-friendly due to the adoption of the environment-friendly plant resin and the addition of the photocatalyst, has better adhesive force and self-cleaning capability, does not pollute the surrounding environment and can purify the household environment.

Description

A clear wood varnish

technical field

The invention relates to the technology in the field of wood varnish, in particular to a clear wood varnish.

Background technique

With the improvement of living standards, people have higher and higher requirements for the quality and smell of coatings, especially in terms of environmental protection. At present, the paint at this stage is difficult to satisfy. The residual smell of formaldehyde and VOC is still very serious within one or two months after the construction is completed, which seriously affects people's life and living quality. In real life, wooden furniture is mostly used, and these furniture are being processed. The paints painted at the time all have volatile substances, which will not cause any degradation to the environment while polluting the surrounding environment. In all aspects of the use of furniture, they are arranged in every corner of the home. If they can be used, they will be intentional. unexpected effect.
