Problems solved by technology

[0003] Among the primers prepared by the existing preparation methods, many primers use formaldehyde, toluene, and xylene as organic solvents. Many people may only know that formaldehyde can induce allergic asthma. Mutations and chromosomal damage can also cause nasopharyngeal carcinoma hazards in humans
However, they do not know that toluene and xylene are also very harmful. People who inhale high concentrations of toluene or xylene in a short period of time will experience symptoms of central nervous anesthesia, such as dizziness, nausea, chest tightness, and fatigue in mild cases, and coma in severe cases. Even death due to respiratory and circulatory failure, chronic benzene poisoning can irritate the skin, eyes and upper respiratory tract
[0004] Using formaldehyde, toluene, and xylene as organic solvents not only harms the human body, but also pollutes the environment and greatly reduces air quality

Abstract

The invention discloses a preparation method of an environment-friendly primer for solid wood furniture. The method includes: adding rosin resin, amber resin and shellac resin into a container containing an organic solvent, and starting a stirrer at a stirring speed of 280-380r / min to fully dissolve the rosin resin, amber resin and shellac resin; adding polyamide resin and alkyd resin into the container, at the same time adding a dispersant, and conducting microwave treatment under a microwave frequency of 1600-2000MHz for 4-8min; adding filler into the container, raising the temperature to 65-75DEG C, then adding a defoaming agent, increasing the stirring speed to 400-600r / min, and carrying out heat preservation reaction for 30-50min; then adding an anti-settling agent into the container, and performing stirring for 4-9min, thus obtaining the environment-friendly primer. The method provided by the invention adopts rosin resin, amber resin and shellac resin to substitute part of othersynthetic resin, and improves the adhesion and impact resistance of the primer, also the organic solvent is free of toxic substance, is environment-friendly and pollution-free, the preparation methodis simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of primers, in particular to a preparation method of an environmental-friendly primer for solid wood furniture. Background technique [0002] The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure the uniform absorption of the topcoat and make the paint system play its best good effect. [0003] Among the primers prepared by the existing preparation methods, many primers use formaldehyde, toluene, and xylene as organic solvents. Many people may only know that formaldehyde can induce allergic asthma. Mutations and chromosomal damage can also cause NPC hazards in humans. However, they do not know that toluene and xylene are also very harmful. People who inhale high concentrations of toluene or xylene in a short period of time...
