Wood protective agent as well as preparation method and application thereof

Abstract

The invention relates to a wood protective agent as well as a preparation method and application thereof. The wood protective agent comprises the following components, by weight, 10-30 parts of phenolic aldehyde-rosin composite modified resin, 1-2 parts of an emulsion, 1-3 parts of a reinforcing penetrating agent, 3-10 parts of an anti-corrosion and insect-resistant agent, 1-5 parts of an assistant and 55-80 parts of water. The wood treated by the wood protective agent is greatly improved in the aspects of insect resistant, anti-deformation cracking and anti-corrosion performance, moreover, the dimensional stability and the mechanical properties such as hardness and density of the wood are improved, so that the use grade of the wood is remarkably improved, and the service life of the woodis prolonged; and the modified wood has the natural attributes such as temperature adjustment, humidity regulation and the like, color is bright and light, the three-dimensional sense of the physicalstripes is strong, and the color of panel is transparent and natural.

Description

technical field [0001] The invention relates to a wood protective agent and its preparation method and application, belonging to the technical field of wood processing. Background technique [0002] In the field of wood protection research, the type and treatment process of the protective agent are the key factors to determine the effect of wood protection treatment. However, the currently commonly used protective agents have the defect of single function, including water-soluble preservatives copper chromium arsenic (CCA), ammonia-soluble alkylamine copper (ACQ) and copper azole, etc., are all wood preservatives with single function, and cannot be taken care of at the same time. Anti-corrosion function, dimensional stability, hardness and avoiding deformation and cracking. [0003] The existing wood modification technology, such as simple resin impregnation treatment, can only improve the mechanical properties of the treated wood such as dimensional stability, density and ...

Problems solved by technology

However, the currently commonly used protective agents have the defect of single function, including water-soluble preservatives copper chromium arsenic (CCA), ammonia-soluble alkylamine copper (ACQ) and copper azole, etc., are all wood preservatives with single function, and cannot be taken care of at the same time. Anti-corrosion function, dimensional stability, hardness and avoiding deformation and cracking, etc.

[0003] Existing wood modification technologies, such as simple resin impregnation treatment, can only improve the mechanical properties of the treated wood such as dimensional stability, density and hardness, and the treated wood does not have the function of anti-corrosion and insect resistance

Moreover, the wood treated with a single phenolic resin has a darker color, which affects the aesthetic effect of the wood, while when the wood is treated with a single rosin modified resin, its permeability is poor, and it is difficult to achieve the enhanced effect
