AI Technical Summary

Problems solved by technology

Because wood products will inevitably come into contact with high temperature, high humidity or high acid and alkali environment during use, these will seriously affect the service life of wood products
Especially in a humid environment, the wood product itself cannot be anti-corrosion and moisture-proof, and it is especially easy to breed mold, which will cause damage to the wood product
[0003] At present, the commonly used method is to carry out surface treatment on the surface of wood products, such as coating protective agents, but the existing protective agents have various problems such as environmental protection and poor protective effect.

Abstract

The invention discloses a mildew-proof woodwork protectant which is prepared from the following components in parts by weight: 1 part of N-methyl-2-pyrrolidinone, 5 to 10 parts of shellac, 6 to 15 parts of water-soluble rosin, 15 to 25 parts of silicone oil, 15 to 25 parts of glycerin, 30 to 40 parts of self-crosslinked acrylic emulsion, 30 to 45 parts of polyvinylidene chloride emulsion and 50 to 65 parts of beeswax. The protectant is tested to have a relatively good killing and inhibition effect on common mildews in a residential environment, still has a relatively good mildew-proof effect after being placed for 3 years in humid air, and can be used for long. In addition, the protectant is short in film-forming time, relatively short in surface drying and hard drying time and relatively high in viscosity.

Description

technical field [0001] The invention relates to a protective agent, in particular to an anti-mold wood product protective agent and a preparation method thereof. It belongs to the technical field of wood products. Background technique [0002] With the advancement of science and technology and social development, people's living standards and living environment are also constantly improving. Wooden products are an indispensable part of people's home life, and are also widely used in many craft decoration materials. Because wood products will inevitably come into contact with high temperature, high humidity or high acid-base environment during use, these will seriously affect the service life of wood products. Especially in a humid environment, the wood product itself cannot be anti-corrosion and moisture-proof, and it is especially easy to breed mold, which will cause damage to the wood product. [0003] At present, the commonly used method is to carry out surface treatmen...
