A long-acting antifungal agent for outdoor bamboo products and its preparation method

Abstract

The invention discloses a long-acting mildew inhibitor for outdoor bamboo products and a preparation method thereof, the long-acting mildew inhibitor comprises 2.75 to 35 parts by weight of a main agent and 65 to 97.25 parts of an auxiliary agent, wherein the main agent comprises three preservatives of azoles, isothiazolinones and pyrethroids. The auxiliary agent comprises water, an emulsifier, adispersant, a penetrating agent and a cross-linking agent. The long-acting mildew inhibitor is prepared from the main agent and the auxiliary agent by emulsification, crosslinking, dispersion, compounding and other processes. The long-acting mildew inhibitor can achieve that bamboo materials processed by the long-acting mildew inhibitor do not mildew for 6 months in outdoor environment by the synergistic effect of the three preservatives of the azoles, the isothiazolinones and the pyrethroids, and long-acting mildew inhibition of the bamboo materials in outdoor environment can be achieved.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a long-acting antifungal agent for outdoor bamboo products and a preparation method thereof. Background technique [0002] my country is the main bamboo producing country in the world, with about 5 million hm 2 bamboo forest. Since the end of the 1980s, with the extensive development of bamboo industrialization, the value of bamboo has increased significantly, especially the further development of bamboo wood-based panels, bamboo composite panels, bamboo decoration, furniture, and automobile manufacturing. The application of bamboo With a broader prospect. However, bamboo and its products are often moldy, rotten, and moth-eaten during processing, transportation and use, especially mildew, which not only affects the appearance of bamboo and its products, but also creates conditions for other fungi and insects to harm . Therefore, the anticorrosion and anti-mildew treat...

AI Technical Summary

Problems solved by technology

Bamboo is more prone to mildew than wood. After testing, its effect alone is not ideal, and bamboo will still have different degrees of mildew.

In recent years, many literatures have also reported the anti-mold effects of various compound anti-mold agents, most of which are based on the combination of two active ingredients. The test method adopts the laboratory test method, and there is no outdoor test result.

And the applicant of this patent provides the prescription according to the document to handle the bamboo and carries out the test outdoors, including propiconazole / tebuconazole (ZJFC), DDAC / IPBC and other document commonly used formulas, can only maintain the time of about 0.5-2 months, can not reach the bamboo material.
