Embodiment Construction
[0035] The present invention is further described below by specific embodiment:
[0036] According to the raw material composition and its mass fraction recorded in Table 1, the diatom ooze interior decoration material for purifying formaldehyde was prepared.
[0037] Table 1. Raw material composition and mass parts thereof of diatom ooze decorative material in the embodiment.
[0038]
[0039] Preparation:
[0040] According to the ratio of raw materials in Table 1, dissolve nano-titanium dioxide in water, and disperse to uniformity by ultrasonic to obtain nano-titanium dioxide solution; add modifier to nano-titanium dioxide solution, and after mechanical dispersion, obtain modified nano-titanium dioxide solution; Add the non-toxic nano-titanium dioxide solution into the refined diatomite, mechanically disperse until the refined diatomite completely absorbs the modified nano-titanium dioxide solution, and obtain the modified diatomite powder; powder filler, gel material, re...

Abstract
The present invention discloses a formaldehyde purification diatom mud decoration material and a preparation method thereof. Specifically the formaldehyde purification diatom mud decoration material comprises, by mass, 10.0-30.0 parts of refined diatomite, 20.0-50.0 parts of a powdery filler, 2.0-5.0 parts of redispersible glue powder, 20.0-40.0 parts of a gel material, 0.5-1.0 part of a dispersion medium, 3.0-8.0 parts of nanometer titanium dioxide, 1.0-4.0 parts of a modifier, 3.0-5.0 parts of anti-cracking fibers, and 20-80 parts of water. According to the present invention, with the formaldehyde purification diatom mud decoration material, the formaldehyde purification efficiency can be effectively increased, the purification persistence can be significantly improved, the defects of physical adsorption effect losing caused by saturation, and the like are avoided, and the purification speed can be accelerated; and the formaldehyde purification diatom mud decoration material of the present invention further has characteristics of good thixotropy, appropriate modeling, water resistance, alkali resistance, no powdering, no cracking and other beneficial properties, and concurrently meets process requirements of mechanical spraying, brushing coating, roller coating and the like.
Description
technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a diatom mud decorative material containing modified nano-titanium dioxide with formaldehyde purification function and a preparation method thereof. Background technique [0002] It has become a consensus that environmental pollution will induce pathological changes in the human body. The pathogenic bacteria, PM2.5 fine particles and pathogenic and carcinogenic organic substances permeating the living environment have attracted more and more attention. The formaldehyde, volatile organic compounds (Volatile Organic Compounds, VOC), fine dust particles, toxic Composition has become the number one concern for consumers after a home renovation. Among them, formaldehyde is a colorless gas with a strong pungent smell. It is very volatile at room temperature, and the volatile amount increases with the increase of temperature. It has a strong stimulating effect on...
