Abstract

The invention discloses a diatomite environmental-friendly wall paper and a preparation method thereof. The preparation method provided by the invention comprises the following steps of: (1) putting dispersant and water into a high-speed disperser to be uniformly agitated and then adding diatomite and de-foaming agent; agitating to prepare diatomite dispersion solution; (2) adding sizing material, thickening agent, water-retaining agent and plasticizer to prepare a diatomite coating; and (3) coating the diatomite coating on the base paper of the wall paper by the way of roll coating or knife coating to prepare the diatomite environmental-friendly wall paper. The coating prepared by the method has a good stability and the solid content of the coating is easy to be adjusted so that the coating is good for carrying out a coating operation of the wall paper; the diatomite environmental-friendly wall paper provided by the invention has the advantages that: the strength satisfies the requirements of the wall paper; the designs, colors and styles are abundant; the paper has a humidity adjusting function so that the paper can better adjust the humidity of the room; and the paper is health, energy-saving and environmental-friendly.

Description

technical field [0001] The invention relates to pulping and papermaking engineering technology, in particular to a production technology of a new type of paper in special papermaking in the papermaking industry process, in particular to diatomite environmental protection wallpaper and a preparation method thereof. Background technique [0002] At present, most of the wallpapers are ordinary coated papers, and the wallpapers are now widely used in interior decoration such as houses, offices, hotels, etc., to obtain a certain decorative effect. But wallpaper, like other decorative materials, is constantly developing and changing with the development of world economy and culture. The use of wallpaper in different periods is a reflection of the comprehensive factors of local economic development level, new material science, and popular consumer psychology. With the continuous improvement of people's living standards and quality of life requirements, more and more people pay mor...
