Nanometer tungsten oxide photocatalyst paper-base bamboo curtain manufacturing method and product thereof

Abstract

The invention relates to a paper-base bamboo curtain manufacturing method and a product thereof, in particular to a nanometer tungsten oxide photocatalyst paper-base bamboo curtain manufacturing method and a product thereof. The method sequentially comprises the following steps that (1), ammonium tungstate solutions are heated under 50-80 DEG C and then are cooled, then ethyl alcohol is added into the ammonium tungstate solutions to form a first latex solution, then cationic surface active agents are added to protect colloid, and mechanical mixing dissolving and refining are used for obtaining a second latex solution; (2) paper-base fibers and a bamboo curtain are combined to obtain a paper-base bamboo curtain; (3) the second latex solution obtained in the step (1) is sprayed to the paper-base bamboo curtain obtained through in the step (2) to form a film, and a nanometer tungsten oxide photocatalyst paper-base bamboo curtain is obtained. The parameters of the manufactured bamboo curtain are that each clearance is smaller than 0.35mm in average, the bonding strength is larger than 0.20Mpa, formaldehyde emission is smaller than 0.5mg / L, antibacterial property is higher than 70%, and water content is 7-13%. According to the nanometer tungsten oxide photocatalyst paper-base bamboo curtain, tungsten oxide content in the paper-base bamboo curtain has good function effect in optic self-catalytic degradation Voc, deodorization, antibiosis and sterilization and the like, and cost can be lowered.

Description

technical field [0001] The invention relates to a method for preparing a paper-based bamboo curtain and its products, in particular to a method for preparing a paper-based bamboo curtain with a nanometer tungsten oxide photocatalyst and its products. Background technique [0002] In the past two decades, due to changes in life and work patterns, modern people spend more and more time indoors, and almost 90% of their time is spent indoors. As a result, a large number of "sick buildings" are caused by poor indoor air quality, as well as "Sick Building Syndrome", "Building Related Illness" and "Multiple Chemical Allergies" (Multiple Chemical Allergies) —chemical Sensitivity) is increasing. People have found that due to the widespread use of new building materials, especially chemically synthesized building materials, high-end furniture and household appliances have entered homes and offices one after another, and cosmetics, polishes, air fresheners, insecticides and detergents...

AI Technical Summary

Problems solved by technology

Although TiO2 has high activity and stability, but the band gap of TiO2 is large (~3.2eV), it can only be excited by short-wavelength ultraviolet light, and the photoconversion efficiency is very low (less than 4%)

[0006] At home and abroad, there are some studies on the photocatalyst treatment of textile, bamboo and wood materials. Beijing Forestry University recently reported that the use of molecular sieves and nano photocatalysts (TiO2) to form formaldehyde adsorbents to treat wood plywood has achieved certain results, but it is molecular sieves that work. It is still the photocatalyst (TiO2) that works, or the joint effect is not clear. In addition, the light conditions of the photocatalyst are not explained.
