Heat treatment and chemical treatment method for improving mildew-proof and antibacterial effects of bamboo strips

Abstract

The invention discloses a heat treatment and chemical treatment method for improving mildew-proof and antibacterial effects of bamboo strips. The method comprises the steps that mildew-free three-year-old moso bamboo strips which are complete in appearance are selected, bamboo inner skin and bamboo outer skin are removed, the bamboo strips are soaked in a water bath then are taken out and are soaked in a hydrogen peroxide solution, then are taken out, are subjected to fully washing and are soaked in cleat water, and then are put into a boric acid solution for treatment, so that chemically treated moso bamboo strips are obtained; then dry heat treatment is carried out to obtain the bamboo strips subjected to the heat treatment; nano-zinc oxide modified by a silane coupling agent, cinnamyl alcohol and ethanol are mixed and are uniformed after ultrasonic dispersion, and then are sprayed on the pretreated bamboo strips; and a halloysite nanotube-loaded mildew-proof agent is added into an organic silicon-acrylic emulsion, after stirring, coating treatment is carried out on the moso bamboo strips subjected to spraying treatment in a brushing mode, and coated bamboo strip samples are placed in a dark place, and are ventilated and dried by air. According to the heat treatment and chemical treatment method, the silane modified zinc oxide has an inhibition effect on growth of mould, andcan change the permeability of a mould cell membrane so that the metabolism of the mould can be influenced.

Description

technical field [0001] The invention belongs to the technical field of wood handicraft treatment technology, and in particular relates to a method for improving the anti-mold and antibacterial properties of bamboo strips through heat treatment and chemical treatment. Background technique [0002] my country is quite rich in bamboo resources. Bamboo-plastic composite materials have the advantages of high utilization rate of bamboo resources, good material mechanical properties, and good product processing performance. Bamboo-plastic composite materials have broad application prospects in the fields of construction, municipal administration, decoration, and logistics. Because bamboo-plastic composite materials will be mildewed in a high-humidity environment, resulting in material performance degradation and environmental pollution, therefore, the problem of mildew resistance has become one of the key issues to be solved in the production and application of bamboo-plastic compos...

AI Technical Summary

Problems solved by technology

[0003] Bamboo and its composite materials have excellent physical and mechanical properties and are widely used, but they are very easy to be infected by mold. When the bamboo treated with antifungal agent is used outdoors, it is easy to lose the antifungal agent when it is washed by rain, which affects the bamboo. Protective effect life, some also cause environmental pollution
