Antimicrobial wood softener containing nanometer titanium dioxide and preparation method thereof

Abstract

The invention discloses an antimicrobial wood softener containing nanometer titanium dioxide. According to the wood softener, traditional aqueous ammonia, sodium potassium tartrate tetrahydrate, quaternary ammonium salt of chitosan and the like are mixed to prepare a fundamental softening solution, and sericin powder and the nanometer titanium dioxide are added to the fundamental softening solution. Because nanometer particles permeate the wood, the strength of wood can be effectively improved, and the weather-proof performance and the ageing-resistance performance can be improved. Meanwhile, the nanometer titanium dioxide has a certain antimicrobial property. Because sericin adheres to the surface of fiber after cross-linking and solidity, the effects that the breathability of the fiber is improved and the wood is friendlier to the skin are achieved. The softened wood is better in plasticity, and dried and solidified workpieces are high in strength, resistant to bacteria, friendly to the skin and not prone to discoloring and ageing. Therefore, compared with a traditional treatment method, the antimicrobial wood softener containing the nanometer titanium dioxide is more efficient, and the additional use value of the wood is improved.

Description

technical field [0001] The invention relates to the technical field of wood softening treatment, in particular to an antibacterial wood softener containing nano titanium dioxide and a preparation method thereof. Background technique [0002] Wood is a material that lacks plasticity. When wood is processed into products, it often needs to undergo a series of softening treatments to improve its plasticity so that it can be shaped with later processing. The commonly used softening treatment methods are physical methods such as boiling, spray steaming, or chemical liquids such as liquid ammonia and liquid alkali for softening treatment. The traditional treatment methods generally have the problem of reduced strength of wood fibers, which greatly affects The performance of the product after plasticization and molding. Contents of the invention [0003] The object of the present invention is to provide an antibacterial wood softener containing nano-titanium dioxide and a prepar...
