Problems solved by technology

Of course, the current wallpaper is different from the wallpaper more than ten years ago. It is a green and environmentally friendly high-tech product. In addition to being used for decoration, in order to respond to the national call for energy conservation and emission reduction, its thermal insulation and fire prevention are also indispensable. However, the thermal insulation performance of wallpaper is still at a relatively low level, and the fire performance is not good.

Abstract

The invention relates to thermal-insulation wallpaper. The thermal-insulation wallpaper comprises a wallpaper base body and a thermal-insulation coating arranged on at least one side of the wallpaper base body, wherein the thermal-insulation coating contains titanium dioxide coated glass hollow microbeads. According to the thermal-insulation wallpaper disclosed by the invention, the titanium dioxide is utilized to coat the glass hollow microbeads and especially in-situ coat the glass hollow microbeads, the glass hollow microbeads and fumed silica are synergistically used to obtain flame-retardant high-efficiency thermal-insulation wallpaper pulp, the thermal-insulation wallpaper pulp is coated to pure-paper wallpaper, and the flame-retardant thermal-insulation wallpaper can be obtained through curing.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a functional wallpaper, in particular to a thermal insulation wallpaper. Background technique [0002] Building energy consumption generally accounts for 30-40% of the total energy consumption of human beings. Thermal insulation materials and products are an important factor affecting building energy conservation. The development and application of building insulation materials have been paid more and more attention by countries all over the world. After the 1970s, foreign countries generally paid attention to the production of thermal insulation materials and their application in construction, and strived to greatly reduce energy consumption, thereby reducing environmental pollution and greenhouse effect. The development of China's thermal insulation materials is relatively slow, but after more than 30 years of hard work in China's thermal insulation material industry, especially after...
