Photocatalyst suspension, anti-adhesion self-cleaning artificial board decorative paper and preparation method thereof

Abstract

The invention discloses nano titanium dioxide suspension. By optimization of selection and proportion of raw material components, a visible light absorption wavelength range is effectively expanded, efficient negative ion dissociation capability is achieved after surface coating formation, and accordingly better air purification and bactericidal efficacies can be achieved. By introduction of nano graphene oxide excellent in thermal conductivity and electricity conductivity into the raw material components, the suspension has excellent anti-adhesion and antistatic performances after solidification. The nano titanium dioxide suspension is high in stability, and a preparation method is simple, high in operability and beneficial to industrial large-scale production. The invention further discloses anti-adhesion self-cleaning artificial board decorative paper. The surface of the anti-adhesion self-cleaning artificial board decorative paper is coated with a nano titanium dioxide photocatalyst coating, an efficient negative ion release performance is achieved, and a preparation method of the decorative paper has advantages of simplicity, high efficiency, environmental friendliness and the like. Laminated artificial decorative boards meet requirements of JC / T2110-2012 Indoor Air Ion Concentration Test Method.

Description

technical field [0001] The invention relates to the field of artificial decorative materials, in particular to an anti-adhesion self-cleaning artificial board decorative paper and a preparation method thereof. Background technique [0002] There are a large number of organic pollutants such as bacteria and formaldehyde in people's living environment, working environment and living environment, which will seriously harm people's health. In recent years, with the improvement of living standards, people pay more and more attention to the prevention and control of diseases. Improving the home and working environment has become an urgent expectation and need of the public, which greatly promotes the technological development of clean and environmentally friendly decorative materials. Among them, artificial decorative paper plays an important role in home decoration, but there are still quality bottlenecks in the decorative paper industry, especially the modification of environmen...

Problems solved by technology

Among them, artificial decorative paper plays an important role in home decoration, but there are still quality bottlenecks in decorative paper in the industry, especially the modification of environmental protection functions is still in the exploratory stage, and the products on the market cannot fully meet people's needs.

[0003] In the production process of melamine impregnated paper, due to its own process characteristics, before the urea-formaldehyde glue and melamine glue are not completely cured, there are a large number of hydrophilic groups, such as hydroxyl (-OH) and amino (-NH2), and the hydrophilic groups are easy to Absorb moisture in the air, partially dissolve urea-formaldehyde resin and melamine-formaldehyde resin, and make the bottom of the stacked upper layer of paper and the front of the next layer of paper stick together under the action of gravity, resulting in a quality that is not easy to separate or tear and scrap question

The traditional photocatalyst nano-tourmaline or pure nano-titanium dioxide powder can only absorb ultraviolet light below 400nm. In the natural environment, the proportion of ultraviolet light is low, less than 10% of natural light, that is, nano-tourmaline and titanium dioxide need to be exposed to strong ultraviolet light. , to dissociate negative ions to decompose volatile organic compounds and kill bacteria, but indoors often do not have such a strong light source, and the environment with ultraviolet lights on is harmful to the human body, so ordinary photocatalysts have little self-cleaning effect indoors
