Embodiment 1

[0024] The water-based one-component polyurethane wood lacquer of the embodiment of the present invention is composed of the following components by weight: 81% of water-based one-component polyurethane, 1% of epoxy siloxane, 1.5% of water-soluble silicone, and 16.5% of water.

[0025] The preparation method of the water-based one-component polyurethane wood varnish based on the embodiment of the present invention is:

[0026] (1) Prepare raw materials: water-based one-component polyurethane dispersion, epoxy siloxane, water-based silicone, water;

[0027] (2) Under normal temperature conditions, firstly put into water-based one-component polyurethane dispersion;

[0028] (3) under the rotating speed of 350-650 per minute, put into epoxy siloxane and water-based organosilicon sequentially in proportion;

[0029] (4) Then, at a rotating speed of 700-1400 per minute, disperse at a high speed for 15 minutes, control the temperature below 50 °C, and control the fineness to be les...

Abstract

The invention provides a preparation method based on water-based one-component polyurethane wood lacquer, which belongs to the field of water-based wood lacquer manufacturing. In order to improve product quality and production efficiency, a kind of preparation technology based on water-based one-component polyurethane wood lacquer of the present invention comprises the following steps: (1) preparing raw materials; (2) under normal temperature conditions, at first drop into water-based one-component polyurethane Dispersion; (3) at a speed of 350-650 per minute, add water-soluble cellulose ether or epoxy siloxane, water-based silicone in proportion; (4) at a speed of 700-1400 per minute , disperse at high speed for 15 minutes, control the temperature below 50°C, and control the fineness to be less than or equal to 25 microns; (5) After the detection fineness reaches 25 microns or less, reduce the dispersion speed to 400 rpm, put in water, and disperse for 10 minutes; (6) Take out the material from the disperser, filter and pack with a 300-mesh filter screen. The water-based one-component polyurethane wood paint obtained by the preparation process provided by the invention improves the product physical properties of the water-based one-component polyurethane.

Description

technical field [0001] The invention relates to a manufacturing method based on water-based single-component polyurethane wood varnish, belonging to the field of water-based wood varnish manufacture. technical background [0002] With the improvement of people's quality of life and high attention to health, the future home decoration and furniture coatings market must be the world of water-based paint. The promotion of water-based wood coatings is very beneficial to the rational use of resources and the improvement of environmental sanitation. Due to the enhanced operability of the construction of water-based wood coatings, well-known domestic decoration companies plan to use water-based wood coatings in an all-round way, and train painters to form a corresponding construction team to launch a water-based movement. Today, with the increasing emphasis on coating safety and environmental protection indicators, water-based wood coatings are gradually being accepted by the mark...
