Heavy wood with mildew-prevention function and preparing method thereof

Abstract

The invention discloses heavy wood with a mildew-prevention function and a preparing method thereof. An efficient mildew preservative and low-molecular-weight bakelite are added into bamboo bunches, and the mildew resistance of the heavy wood is effectively improved. The mildew preservative is composed of three preservatives of azoles, isothiazolinone and pyrethroid, an auxiliary is composed of water, emulgator, dispersing agent, penetrant and cross-linking agent, a main agent and the auxiliary are prepared through the procedures of emulsification, crosslinking, dispersion, compounding and thelike, and through the synergistic effect of azoles, isothiazolinone and pyrethroid, the mildew preservative expands a bacteriocidal spectrum and reduces the dosage. The purpose that the heavy wood does not go mildewed under an outdoor environment of processed bamboo woods for 6 months can be achieved, and long-acting mildew prevention of the heavy wood can be achieved. After bakelite is adopted to make the wood recombined and glued, the preservative is sealed in bakelite and does not run off, and compared with common mildew-prevention wood, the heavy wood is 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.
