Technical Field

The invention relates to the technical field of wood treatment, in particular to a wood anti-cracking and mothproof treatment process for a pet nest.

Background

As pets increasingly enter families, the demand of people on pet products is gradually increased, for example, pet nests made of wood materials are deeply loved by people, in order to reduce cracking and deformation of wood products, the common method is to paint the surface of the wood products so as to reduce the influence of external humidity on the wood products, but because the paint can not be treated to the deep layer of the wood, after the wood products are used for a period of time, a treatment layer can be worn off, in addition, the paint can change the natural color of the wood, and because the paint is influenced by self particles and self expansion of the paint, the influence of the external humidity on the wood products can not be well reduced when the paint is painted on the surface of the wood products, the paint film is easy to crack after a long time, meanwhile, the traditional paint is mostly made of chemical products and contains a large amount of toxic and irritant components, thus causing harm to the pets, therefore, a wood anti-cracking and mothproof treatment process for pet nests is provided.
