Abstract

The invention discloses a wood surface protection nano coating. The coating comprises, by weight, 25-27 parts of nano silica, 25.5-26.5 parts of n-butyl alcohol, 5.5-6.5 parts of butyl acetate, 3.5-4.5 parts of TEOS, 1.5-2.5 parts of sodium carboxymethylcellulose, 3.5-4.5 parts of silane coupling agents, 15.5-16.5 parts of isocyanate and 15.5-16.5 parts of polyglycol ether. Meanwhile, the invention discloses a technology for preparing the wood surface protection nano coating. The wood surface protection nano coating can be used for surface protection of various sorts of wood for furniture, building wood structures, outdoor wood structures, wood floors and the like. At a normal temperature, the surface of wood can be deeply permeated, a compact and hard inertia protecting film is formed on the surface of the protected wood, various lesion problems of the wood are solved, the fullness, color saturation, texture, permeability and surface hardness of the surface of the wood are improved, and the wood surface protection nano coating further has the advantages of being easy to clean, resistant to contamination, waterproof, resistant to abrasion and the like.

Description

technical field [0001] The invention relates to a nano-coating for surface protection, in particular to a nano-coating for wood surface protection and a manufacturing process thereof. Background technique [0002] Wood surface is not only the main factor to determine the quality, use value and commodity price of wood products, but also the initial impression of people's visual perception. Due to the influence of climate and biological factors in the environment, many chemical and physical changes will occur on the surface of wood, such as dry shrinkage, swelling, cracking, and distortion caused by climate change, mildew and decay under high temperature conditions, insects, insects, etc. Corrosion caused by fungal decay, etc. These changes will not only cause the wood surface to lose its original natural color and texture, but also limit the utilization and processing of wood, which will seriously endanger people's personal safety. Therefore, in order to protect the charact...
