Abstract

An attapulgite-based inner wall brick with environmental protection function and its preparation method, characterized in that the proportions of raw materials by weight are as follows: 55-70 parts of attapulgite clay, 15-30 parts of sepiolite clay, 5-10 parts of tourmaline powder, 5-15 parts of diatomaceous earth, 10-20 parts of enhanced cooling agent, and 0.2-0.5 parts of nano-scale iron-based titanium dioxide. The characteristics of the present invention are: the technology is advanced, the product manufacturing process will not cause any pollution; the raw materials used are non-toxic, harmless, radiation-free and pollution-free; the product has strong adsorption capacity, has the ability to adjust humidity, and has certain heat preservation and sound absorption properties , the strength meets the relevant standards, has the functions of sterilization, deodorization, mildew resistance, anti-fouling and self-cleaning, and is an interior decoration material with environmental protection functions.

Description

technical field [0001] The invention belongs to a house interior wall decoration material, in particular to an attapulgite soil-based interior wall brick with an environmental protection function and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for the living environment are getting higher and higher; at the same time, the environmental pollution continues to intensify and the formaldehyde and benzene series emitted by house decoration materials exceed the standard, which seriously endangers people's living environment. [0003] At present, the decorative materials widely used on interior walls and roofs are latex paint and wallpaper, and functional materials such as diatomaceous earth as adsorption materials are on the rise. Attapulgite refers to a clay mineral with attapulgite as the main component, referred to as "attapulgite". It is a kind of hydrous magnesium-rich silicate clay mineral wi...
