Abstract

The invention discloses a decorative material and a preparation method thereof, and the decorative material is prepared from the following raw materials in parts by weight: 20-30 parts of white cement, 10-20 parts of a modified activated carbon-rectorite composite material, 8-15 parts of quartz powder, 3-5 parts of barium stearate, 2-4 parts of magnesium oxide, 3-5 parts of aluminum oxide, 4-8 parts of redispersible latex powder and 30-50 parts of deionized water. The rectorite is subjected to high-temperature calcination at first, so that the rectorite is indefinite, the pore structure of the rectorite is enriched, the formaldehyde adsorption capacity of the rectorite is improved, then the rectorite is modified, more hydroxyl groups and carboxyl groups can be generated by the rectorite, subsequent reaction is facilitated, and the formaldehyde adsorption capacity of the rectorite is improved. The modified rectorite is used as a raw material, then the interlayer of the modified rectorite is filled with the modified activated carbon in a physical and chemical effect combined mode, the pore diameter uniformity of the rectorite is improved, the formaldehyde adsorption performance of the rectorite is further improved, and meanwhile through the synergistic effect of the modified activated carbon and the modified rectorite, the purpose of rapidly adsorbing formaldehyde can be achieved.

Description

technical field [0001] The invention relates to the technical field of decoration material preparation, in particular to a decoration material and a preparation method thereof. Background technique [0002] Formaldehyde is a colorless gas with a strong irritating odor. It is very volatile at room temperature. The volatile amount increases with the increase of temperature. It has a strong stimulating effect on human skin and mucous membranes. It is converted into methanol, which has adverse effects on the optic nerve. Long-term exposure to low-dose formaldehyde can easily lead to chronic respiratory diseases, pregnancy syndrome, and reduced physical fitness of newborns. In severe cases, it can even cause nasopharyngeal cancer. etc. are toxic. Therefore, my country's standard stipulates that the formaldehyde concentration in indoor air should not be greater than 0.08mg / m2 3 , and the formaldehyde concentration in the air of public places shall not exceed 0.12mg / m 3 . [00...
