Problems solved by technology

[0003] However, after most of the existing wooden products are processed, the surface is prone to unevenness and unevenness, and the paint can not be fully integrated and contacted with the surface of the wooden product, so that its protective effect is greatly reduced; and in the existing wooden products In the paint, there is the problem of poor water resistance. In the long-term use process, the water resistance will gradually decline with the passage of time, which greatly reduces the service life of products and wood products.

Embodiment 1

[0032] An environment-friendly strong water-resistant wood paint, which is composed of a primer paint and a coating paint, and the raw materials in the primer paint are respectively 55% water-based acrylic resin, 30% filler, and 10% lauryl Sodium sulfate and 5% methyl silicone oil; the filler is mixed with wood powder, mica powder, micro wax powder and calcium silicate powder in a weight percentage of 1:1:1:1;

[0033] The primer paint is prepared by the following method: firstly introduce the water-based acrylic resin and methyl silicone oil into the mixing tank, blend at 300 rpm and 90 degrees for 30 minutes, and then add the filler and sodium lauryl sulfate together Introduce it, and blend at 210 rpm, pressurized at 2.5MPa and 60 degrees for 90 minutes, reduce the temperature under reduced pressure, filter to remove impurities and concentrate to 2 / 5 to obtain the primer;

[0034] The raw materials in the coating paint are respectively 50% deionized water, 20% modified base ...

Embodiment 2

[0045] A kind of environment-friendly strong water-resistant wooden ware paint, differs from embodiment 1 in that it is only made up of coating paint material, without primer paint material and related content thereof;

[0046] And the application method of the environmental-friendly strong water-resistant wood lacquer is as follows: first, the coating paint is heated to 75 degrees, and then it is evenly coated on the surface of the wooden product, and after being dried by hot air, the coating paint surface is obtained.

[0047] A kind of preparation method of environment-friendly strong water-resistant wood lacquer, differs from the embodiment 1 in that it only consists of the preparation of coating paint, without 1) the preparation of bottom paint.

Embodiment 3

[0049] An environment-friendly strong water-resistant wood varnish, the difference from Example 1 is that the modified base material is completely replaced with acrylic resin, and the relevant content on the preparation of the original modified base material is deleted.

[0050] A preparation method of an environment-friendly strong water-resistant wood lacquer, the difference from Example 1 is that 2) the modified base material is all replaced by acrylic resin in the preparation of the coating paint.

Abstract

The invention discloses an environmentally-friendly and super-waterproof wood lacquer and a preparation method thereof. The wood lacquer a primer paint and a coating paint, and the primer paint comprises 55 wt% of water-based acrylic resin, 30 wt% of a filler, 10 wt% of sodium lauryl sulfate and 5 wt% of methyl silicone oil; and the coating paint comprises 50 wt% of deionized water, 20 wt% of a modified base material, 15 wt% of a modified waterproof assistant, 9 wt% of Texanol, 4 wt% of polydimethylsiloxane and 2 wt% of nonylphenol polyoxyethylene ether. The repairing, leveling and waterproofing capability of the primer paint is combined with the double water resistance of the modified waterproof assistant in the coating paint and the waterproof promoting effect of the modified base material to make the wood lacquer have a super waterproof effect, and bridge combination can be formed between the primer paint and the coating paint according to the consumption of a hydrophilic group and the change of a hydrophobic form in order to make the primer paint and the coating paint stably combined.

Description

technical field [0001] The invention relates to the technical field of wood lacquer, in particular to an environment-friendly strong water-resistant wood varnish and a preparation method thereof. Background technique [0002] Wood lacquer refers to a kind of resin paint used on wood products. It can be divided into polyester paint, polyurethane paint, acrylic paint and epoxy paint and other categories, and is widely used on furniture, floors and other surfaces as a Protection, decoration and aesthetic purposes. [0003] However, after most of the existing wooden products are processed, the surface is prone to unevenness and unevenness, and the paint can not be fully integrated and contacted with the surface of the wooden product, so that its protective effect is greatly reduced; and in the existing wooden products In the lacquer, there is the problem of poor water resistance. In the long-term use process, the water resistance is easy to gradually decrease with the passage o...
