Background
Bamboo is an important building and engineering material and is receiving more and more attention due to sustainability, availability, good mechanical properties and low cost. After 30 years of development, laminated bamboo, bamboo recombined materials, bamboo oriented strand boards and bamboo fiber reinforced polymer composite materials are favored by consumers, and the bamboo industry becomes one of the Chinese-characteristic eco-friendly, high-added-value, low-carbon and sustainable industries. However, the bamboo contains abundant nutrient substances such as starch protein and fat, and is easy to be corroded by microorganisms in the using process to mildew, so that the resource waste is caused. The mildew of the bamboo wood not only destroys the appearance, color and natural texture of the bamboo wood and various bamboo products, but also seriously affects the economic value and use value of the bamboo wood and various bamboo products. Spores generated by the mold enter human bodies through respiratory tracts and can cause certain harm to the health of people. Therefore, developing the bamboo mildew-proof research is one of the important measures for realizing the efficient and durable utilization of the bamboo.
In order to solve the problem of bamboo mildew, the current methods for processing bamboo can be divided into two types: 1) a chemical method; 2) physical methods. The novel mildew preventive used in the chemical method mainly comprises a copper-boron mildew preventive, a triazole mildew preventive and an isothiazolinone mildew preventive, and the mildew preventives have good mildew resistance. But the problems of loss resistance, alkali resistance and high temperature difference resistance are generally existed. The physical method mainly comprises a water bath cooking method, a high-temperature heat treatment method, ray treatment, ultrasonic treatment and the like, and the methods reduce the nutrient substances for the growth of the mould and change the bamboo material property to inhibit the growth of the mould. Compared with the use of bactericides, the physical mildew-proof technology is more environment-friendly, but the lasting retentivity is poorer.
In recent years, researchers inhibit or reduce the growth of mold through physical methods, chemical methods and other methods, and although certain effects are achieved, the problem that bamboo materials are easy to mildew cannot be completely solved through a single treatment method.
