Environment-friendly mould-proof and anti-discoloration protective agent for rubber wood

Abstract

The invention relates to an environment-friendly mould-proof and anti-discoloration protective agent for rubber wood. Iodopropynyl butylcarbamate ester, an isothiazolinone compound, an organic solvent, a solubility promoter A, a solubility promoter B and water are uniformly mixed to prepare the environment-friendly mould-proof and anti-discoloration protective agent; the solubility promoter A is one of an advanced fatty acid salt surfactant, a quaternary ammonium salt surfactant and a polyhydric alcohol surfactant or a combination of the advanced fatty acid salt surfactant, the quaternary ammonium salt surfactant and the polyhydric alcohol surfactant; and the solubility promoter B is one of a sulphosalts surfactant and an isothiazolinone surfactant or a combination of the sulphosalts surfactant and the isothiazolinone surfactant. The iodopropynyl butylcarbamate ester and the isothiazolinone compound are compounded, stable treatment solution can be formed, and the environment-friendly mould-proof and anti-discoloration protective agent has the advantages of environmental protection, broad spectrum and high efficiency, is good in water solubility and stability, realizes excellent effects for preventing and treating botryodiplodia theobromae, alternaria alternata and the like which severely damage the rubber wood, is applicable to various rubber wood treatment processes such as vacuum-pressure processes, hot and cold bath processes and soaking processes, and can be directly applied to existing production processes conveniently.

Description

technical field [0001] The invention belongs to the field of wood protection, and relates to a rubber wood protective agent, in particular to an environment-friendly rubber wood anti-mildew and anti-discoloration protective agent used to protect log materials from mold and discoloration bacteria during rubber wood processing. Background technique [0002] Rubber trees (Hevea brasiliensis) are mainly planted in Hainan, Yunnan and other provinces in my country. The current national planting area is about 667,000 hectares, and the annual renewal of rubber plantations can provide about 2 million cubic meters of logs. Rubber wood has elegant color, beautiful texture and good processing performance. It is a tree species with high material performance in plantation forests. However, the content of sugar, protein and ash in rubber wood is much higher than that of other tree species, and it is easy to rot, mildew, blue stain and be eaten by pests, so it is difficult to use without tr...

Problems solved by technology

[0003] Although sodium pentachlorophenate has low cost and good effect, it has been banned in the world since the 1980s due to its high toxicity to humans and animals and great harm to the environment.

In the 1990s, the wood antifungal agent product "Antiborer 3767+Antiblu 3738" introduced from the United Kingdom, and the antifungal agent product "Injecta" introduced from Denmark were not only poor in antifungal effect, but also high in cost.

The reason is that these two agents are not designed for the protection of rubber wood and are not suitable for the domestic rubber wood production process.

In 2002, someone introduced a series of fungicide products from Koppers Arch Company, but they failed because they did not adapt to the Chinese market.

[0004] Recently, the Chinese patent CN102265902A discloses a method for preventing mildew of rubber wood. It adopts water boiling treatment, and the treatment time is relatively long. It is also quite different from the current treatment process, and there are certain obstacles in actual production and application.
