Preparation method of raw-lacquer-based wall coating and application technology thereof

Abstract

The invention discloses a preparation method of raw lacquer-based wall coating and an application technology thereof, and provides a preparation method of environment-friendly wall/floor coating having excellent ecological performance and mainly prepared from raw lacquer and a corresponding wall/floor coating product. The raw lacquer is used as a base to prepare the wall or floor coating, the coating comprises the components as follows: the raw lacquer, a filler, a thinner and an addition agent. The coating which is mainly prepared from raw lacquer is technically characterized by containing inorganic whisker, the raw lacquer, an epoxy resin, a coupling agent and the like. By adopting the preparation method, the adhesive force of a coating film can be increased by 0.5 time to 1.5 times or more; the other performances of the coating film are improved as follows: the heat resistance is increased by 32 percent to 117 percent, the corrosion resistance is increased by 24 percent to 119 percent, the flexibility is increased by 37 percent to 107 percent, the acid (dilute acid) resistance is increased by 31 percent to 63 percent, oil resistance is increased by 22 percent to 67 percent, and the abrasion resistance is increased by 28 percent to 88 percent.

Description

[0001] technical field [0002] The invention belongs to the field of ecological and environment-friendly polymer materials, in particular to a polymer coating preparation technology based on biomass-based lacquer developed in China. [0003] Background technique [0004] Raw lacquer, also known as tree lacquer, national lacquer, lacquer, natural lacquer, Chinese lacquer, etc., is a traditional Chinese paint with a long history. Its main chemical component is urushiol. It is a traditional natural high-quality paint and is known as the king of paint. reputation. [0005] According to archaeologists, the application history of raw lacquer in China is at least 8,000 years old. Some people think that this is the fifth or sixth invention in ancient China. Although raw lacquer has been used in China for a long time, the construction conditions of raw lacquer are more demanding than modern industrial paint, especially the construction period of raw lacquer is longer, and the use...

AI Technical Summary

Problems solved by technology

[0008] In addition, the flexibility of the raw lacquer film is poor, that is, the brittleness of the paint film, which is a technical bottleneck problem that needs to be solved in the application of raw lacquer

[0009] Although raw lacquer has excellent performance, it cannot be artificially synthesized because it is derived from natural sources, and the cost is relatively high, and the cost is also high when used for walls and floors

[0010] When raw lacquer is used on the ground, it is still difficult to meet the wear resistance requirements due to its hardness, so the durability needs to be improved
