Problems solved by technology

However, the treatment cost of this method can be further reduced; while improving the flame retardancy of wood, it cannot obviously improve other properties, such as the strength and hardness of wood; in addition, the formula of flame retardant is relatively complicated, which causes relatively complicated process

Embodiment Construction

[0008] 1. Preparation of silica sol and wetting agent

[0009] Commercially available alkaline silica sol can be used, and its pH value is generally 9.0-10.5, which can be 9.0 or 10.5 or 10.0. The silica content of the alkaline silica sol is 10-31%, which can be 10% or 31% or 20% or 25%. In order to achieve a better effect, 0.05 or 0.1 or 0.2 or 0.3 of the wetting agent by weight of the weight of the silica sol can be added to the above-mentioned silica sol. The wetting agent can be JFC or OP-9 or Triton X-100.

[0010] 2. Determination of sufficient infiltration

[0011] The full infiltration means that the weight of the wood material sample after drying no longer increases with the prolongation of the infiltration time. The time for full infiltration of wooden materials of different materials and shapes and sizes is not completely consistent. In actual production, the time for fully soaking wooden materials of the same material, shape and size can be measured first, and ...

Abstract

The invention discloses a method for processing a wood material, which is characterized in that the processing method is finished by fully soaking the wood material into silica sol and then drying the fully soaked wood material, wherein the silica sol is alkali silica sol which contains 10 to 31 percent of silicon dioxide. Because the silicon dioxide has the characteristics of difficult combustion, high strength and harness, corrosion resistance and the like, the wood material processed by the method also has the characteristics of difficult combustion, high strength and harness, corrosion resistance and the like; and the silica sol is only 2,000 Yuan per ton in the prior market, the used silica sol after the concentration of the silicon dioxide is reduced can be doped with the silica sol with higher concentration to be reused, so the method also has the characteristic of low processing cost. On the other hand, the silicon dioxide is a more environment-friendly substance, so the method also has the characteristic of environmental protection.

Description

technical field [0001] The invention relates to a processing method of woody material. Background technique [0002] In practical applications, wood often needs to be treated to have some special effects, such as flame-retardant treatment, anti-corrosion treatment, etc. However, some treatments currently have the disadvantages of inconspicuous effect, complex process or high treatment cost. [0003] The patent document "Wood Flame Retardant and Its Wood Flame Retardant Treatment Process" (publication number CN1911613) published by the State Intellectual Property Office on February 14, 2007 introduces a wood flame retardant and its wood flame retardant treatment process. The fuel formula is: 5-65% of ammonium sulfate, 5-65% of diammonium hydrogen phosphate, 5-65% of boric acid and 5-65% of borax. The wood treatment is as follows: add 10-20% flame retardant to 100kg water, make the soaking tank a vacuum, and input the flame retardant liquid into the soaking pool wood through...
