A kind of recombinant bamboo with anti-mildew function and preparation method thereof

Abstract

The invention discloses a reconstituted bamboo with antifungal function and a preparation method thereof. A high-efficiency antifungal agent and a low molecular weight phenolic resin are added to the bamboo bundle, thereby effectively improving the antifungal properties of the reconstituted bamboo. The antifungal agent used in the present invention is composed of three kinds of preservatives: azoles, isothiazolinones and pyrethroids. The auxiliary agent is composed of water, emulsifier, dispersant, penetrant and cross-linking agent. It is prepared through the processes of emulsification, cross-linking, dispersion and compounding. The preservative can be treated by the synergistic effect of azoles, isothiazolinones and pyrethroids, expanding the bactericidal spectrum and reducing the dosage of drugs. Bamboo material does not get moldy for 6 months in the outdoor environment, and the reconstituted bamboo can achieve long-term mildew resistance; after the phenolic resin is used for recombination and gluing, the preservatives are enclosed in the phenolic resin without any loss. Compared with ordinary preservative wood, the present invention provides The reconstituted bamboo is made more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of bamboo processing, in particular to recombined bamboo with anti-mildew function and a preparation method thereof. Background technique [0002] Recombined bamboo, also known as heavy bamboo, is a new bamboo material that reorganizes and strengthens bamboo. Dipping, then drying to the required moisture content, and then laying in the mold, the profile is cured by high temperature and high pressure. [0003] The anti-mold of recombined wood mainly refers to wood anti-mold technology, and the selection of active ingredients of anti-fungal agents mainly comes from cosmetics, pesticides and other industries. The types of fungicides include chlorothalonil, 8-hydroxyquinoline copper, carbendazim, 3-iodo-2-propynyl-butylcarbamate (IPBC), didecyldimethylammonium chloride (DDAC ), dodecyl benzyl dimethyl ammonium chloride (BAC), propiconazole, etc., including foreign countries have also developed thiocyanate (TCM...

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.
