Wood surface corrosion control method

Abstract

The invention discloses a wood surface corrosion control method. The method comprises the following steps: (1) drying the wood until the water content is about 18%; (2) injecting the preservatives, namely 2-4 parts of propylene glycol, 30-48 parts of propene carbonate, 1-2.3 part of DCOIT, 10-25 parts of p-chloroxylenol, 1-4 parts of alkyl dimethyl benzyl ammonium chloride, 1-2.8 part of sodium chloride, 1-3 parts of sodium chlorate, 1-3 parts of potassium bromide, 5-8 parts of bronopol, 35-46 parts of dithiocyano-methane and 108-116 parts of fatty alcohol polyvinyl chloride ether in part by weight, into the wood under the vacuum high pressure condition; (3) performing high-temperature qualitative treatment for 6-12 hours on the wood after the preservatives are added; and (4) carrying out air drying on the high-temperature qualitatively treated wood to obtain the wood subjected to preservative treatment. The corrosion control method disclosed by the invention is good in corrosion control effect, the preservatives can permeate into the part being 1-2mm of the wood surface, and good mold prevention and corrosion resistance are obtained; the wood is strong in waterproof durability, is loss resistant and long in residual action, the raw materials is easily available, and the cost can be saved.

Description

technical field [0001] The invention relates to an anticorrosion method, in particular to an anticorrosion method for wood surfaces, and belongs to the field of chemical science. Background technique [0002] Wood is an organic material with obvious biological characteristics, and is easily attacked by organisms such as bacteria, insects, and marine borers. Therefore, the long-term use of wood, especially long-term outdoor use, is greatly restricted. Decay organisms cause rot in wood, causing it to become damaged. Before use, according to different application environments, choose suitable preservatives and carry out proper treatment, which can effectively delay wood decay. Carrying out anti-corrosion treatment on wood and prolonging the service life of wood is one of the important ways to save wood and protect forest resources. At present, the wood preservatives used in countries all over the world are mainly CCA preservatives, which are toxic due to arsenic, chromium an...

Problems solved by technology

At present, the wood preservatives used in countries all over the world are mainly CCA preservatives. This kind of preservatives are toxic because they contain arsenic, chromium and other substances, which is not conducive to environmental protection. In some countries, their use has been strictly restricted.
