Problems solved by technology

Compared with the use of fungicides, physical anti-mold technology is more environmentally friendly, but the durability is poor
[0004] In recent years, researchers have used physical methods or chemical methods to inhibit or reduce the growth of mold. Although some results have been achieved, the single treatment method still cannot completely solve the problem of bamboo easy to mildew.

Abstract

The invention belongs to the technical field of mildew prevention for wood and bamboo materials , and particularly discloses a multi-technology coupled mildew prevention treatment method for wood and bamboo materials and application. The method comprises the following steps: firstly, compounding an organic mildew preventive and an inorganic mildew preventive, then carrying out mildew preventive hot bath treatment on a wood and bamboo unit, and finally, brushing mildew preventive improved paint. According to the invention, the mildew resistance of wood and bamboo materials is greatly improved, and the outdoor service life of the wood and bamboo materials is prolonged. The mildew preventive used in the invention is composed of borate, quaternary ammonium salt, pyrethroid, inorganic boron compound, azole and other mildew preventives; an auxiliary agent is composed of water, an emulsifier, a dispersant and a penetrant; and through the synergistic effect of organic / inorganic compounding, mildew preventives hot bath treatment and surface coating, a broad bactericidal spectrum is expanded, durability is improved, the advantage of easiness in operation, preparation and use is obtained, the mildew-proof performance of the wood and bamboo materials in a multi-bacteria complex environment can be improved, and long-acting mildew prevention of the wood and bamboo materials is achieved.

Description

technical field [0001] The invention relates to the technical field of wood and bamboo anti-mildew technology, in particular to a multi-technology coupled wood and bamboo anti-mold treatment method and its application. Background technique [0002] As an important construction and engineering material, bamboo has attracted increasing attention due to its sustainability, easy availability, good mechanical properties and low cost. After 30 years of development, laminated bamboo, bamboo recombined wood, bamboo oriented strand board and bamboo fiber reinforced polymer composite materials are favored by consumers. The bamboo industry has become an eco-friendly, high value-added, low-carbon, One of the sustainable industries. However, bamboo is rich in nutrients such as starch, protein and fat, and is easily eroded by microorganisms during use, resulting in mildew and waste of resources. Bamboo mildew not only destroys the appearance color and natural texture of bamboo and vario...
