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

Embodiment 1

[0032] A kind of wood protection agent of embodiment 1

[0033] A kind of wood protective agent, is made from the following components by mass percentage: 30% of phenolic-rosin composite modified resin, 1.5% of emulsion alkylphenol polyoxyethylene ether-10, enhancing penetrating agent (C7~9 alkanol poly Oxyethylene ether, purchased from Jiangsu Haian Petrochemical Plant, TX-10) 2%, antiseptic and insect repellent (isothiazolinone, propiconazole, disodium octaborate) 4%, auxiliary agent 1,2-propylene glycol 5% , water 57.5%.

[0034] Among them, in the phenolic-rosin composite modified resin, the mass ratio of the phenolic resin to the rosin modified resin is 2:1.

[0035] The antiseptic and insect repellant was purchased from Guangzhou Xinmei Chemical Factory; the mass ratio of isothiazolinone, propiconazole and disodium octaborate was 1:0.125:0.8.

Embodiment 2

[0036] Embodiment 2 A kind of wood protective agent

[0037] A wood protective agent, the difference from the formula of Example 1 is that the specific ratio of phenolic resin and rosin modified resin is 1:1.

Embodiment 3

[0038] Embodiment 3 A kind of wood protective agent

[0039] A wood protective agent, prepared from the following components in mass percentage: the mass fraction of phenolic-rosin composite modified resin is 25% (the ratio of phenolic resin to rosin modified resin is 2:1), the emulsion alkylphenol Oxyethylene ether-10 1%, penetrating agent (C7~9 alkanol polyoxyethylene ether, purchased from Jiangsu Haian Petrochemical Plant, TX-10) 1.5%, antiseptic and insect repellant (isothiazolinone, propiconazole , disodium octaborate) 3.5%, additives 1,2-propanediol 5%, water 64%.

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 ...
