Mildew-proof microcapsule for bamboo wood and preparation method of mildew-proof microcapsule

Abstract

The invention discloses a mildew-proof microcapsule for bamboo wood and a preparation method of the mildew-proof microcapsule. The mildew-proof microcapsule comprises the following components in parts by mass: 1 part of a core material, 0.5-3 parts of a wall material, 0.8-1.5 parts of an emulsifier, 0.2-1.5 parts of a dispersing agent and 0.2-1.5 parts of an acid catalyst, wherein the core material comprises, in parts by weight, 3 to 6 parts of triazole bactericide and 0.8 to 1.5 parts of organic solvent; and the wall material is amino resin. The preparation method comprises the following steps: mixing and stirring the triazole bactericide and the organic solvent to obtain the core material; and mixing the core material and the emulsifier in the amino resin, adding the dispersing agent, carrying out heating for emulsifying to obtain a water-in-oil emulsion, adding the acidic catalyst into the water-in-oil emulsion, and carrying out an in-situ copolymerization reaction to form a microcapsule wall coating system, thereby obtaining the mildew-proof microcapsule. The mildew-proof microcapsule has the advantages of small particle size, excellent anti-mildew effect, good thermal stability and capability of slowing down the leakage rate of the core material.

Description

technical field [0001] The invention relates to a mildew-proof microcapsule for bamboo and a preparation method thereof, belonging to the field of bamboo and wood processing. Background technique [0002] Bamboo is an important part of forest resources, known as the "second forest". Bamboo products such as bamboo flooring, bamboo furniture, and recombined bamboo have been widely used in decoration, furniture, and building structural materials. By 2020, the annual output value of the bamboo industry has reached about 300 billion yuan. As these bamboo materials are gradually applied to outdoor fields such as structural buildings and wetland garden landscape facilities, when they are exposed to the natural environment, they are easily corroded by fungi, which accelerates their mildew and decay, greatly reducing their use value, thus gradually making them useless. The material loses its original excellent performance. At present, the long-acting anti-mildew problem of bamboo p...

Problems solved by technology

However, organic fungicides cannot be uniformly dispersed in water to form a micron or nano-scale protective agent solution; they are easy to be hydrolyzed and photolyzed during storage and use, and are easy to lose, so they cannot provide long-term protection for bamboo wood.
