Environment-friendly long-acting type nano-silver base wood and bamboo material antibacterial mould inhibitor and preparing method and application thereof

Abstract

The invention relates to an environment-friendly long-acting type nano-silver base wood and bamboo material antibacterial mould inhibitor and a preparing method and application thereof. The antibacterial mould inhibitor is rapidly prepared with carboxymethyl chitosan, silver salt and a reducing agent serving as raw materials and water serving as a solvent through an efficient microwave radiation method. According to the prepared nano-silver base wood and bamboo material antibacterial mould inhibitor, silver nanoparticles are uniform in particle size and are evenly distributed in a carboxymethyl chitosan base, and agglomeration is not likely to happen; the nano-silver base wood and bamboo material antibacterial mould inhibitor can be well combined with a wood and bamboo material, has high wide spectrum efficiency and is high in loss resistance and durable in antibacterial effect; and in addition, the particle size is small and viscosity is low so that the antibacterial mould inhibitor can better enter a processed material. According to the method, the raw materials are cheap, the technology is simple, operation is convenient, the production efficiency is high, the product reproducibility is high, no complex and expensive equipment is needed, no pollution is caused to the environment, energy consumption is reduced, and industrial popularization is facilitated.

Description

technical field [0001] The invention relates to the field of antibacterial and antifungal agents for wood and bamboo, in particular to an environment-friendly and long-acting nano silver-based antibacterial and antifungal agent for wood and bamboo, a preparation method and application thereof. Background technique [0002] Wood and bamboo materials have the advantages of beautiful texture, high strength-to-weight ratio, strong processability, and natural degradation. They are widely used in architectural decoration, garden landscape, packaging and transportation, furniture, flooring and other industries. However, as a natural biological material, wood and bamboo tend to become the carrier of microbial attachment and the medium of transmission during storage, transportation and use. The spread and spread of harmful bacteria seriously endanger human health; the erosion of mold seriously affects the appearance quality and service life of wood and bamboo products, causing econom...

Problems solved by technology

Pentachlorophenol is the reaction product of phenol and chlorine. It was popularized and used in 1928. It is widely used in the market, but it has been banned in many countries such as New Zealand because of its high toxicity to humans and animals and serious environmental pollution.

However, the patent uses more toxic chemical reagents in the preparation process, which not only increases the cost, but also poses a threat to human health and the ecological environment.
