Abstract

The invention relates to a water-based wood protective agent and a preparation method thereof. The water-based wood protective agent comprises the following ingredients in parts by weight: 150-400 parts of water-based resin, 3-8 parts of dry film preservative, 3-8 parts of defoaming agent, 10-40 parts of film coalescing aid, 200-400 parts of non-organic silicon auxiliary, 150-300 parts of metal cross-linking agent, 50-150 parts of wax auxiliary and 0-150 parts of deionized water. The water-based wood protective agent is of a green and environmentally-friendly water-based product with ultraloworganic volatile matter content, and is simple to construct and capable of being subjected to brush coating, spray coating and dip coating. After construction, a durable protective layer with a lotusleaf effect can be formed on the surface of a wood product and has good properties of resisting water, corrosion and ultraviolet and relieving wood cracking and deformation.

Description

Technical field [0001] The invention relates to a wood protection agent, in particular to a water-based wood protection agent with lotus leaf effect and a preparation method thereof. Background technique [0002] During the "Eleventh Five-Year Plan" period, my country has set the goals of building a conservation-oriented and environment-friendly society and developing a sustainable and circular economy. At the end of 2005, the State Council forwarded the "Regarding Accelerating the Promotion of Wood Conservation" issued by 12 government departments including the National Development and Reform Commission. And Substitution Work Opinions, requiring the implementation of wood protection technology and extending the service life of wood products. Encourage wood to be treated with anti-corrosion, insect (ant), mildew, drying, flame retardant, and modified protection. Wood used outdoors and as a landscape must undergo anti-corrosion and waterproof treatment to be more economical, more ...
