Abstract

The invention belongs to the technical field of air purification, and relates to a building decoration material with the formaldehyde purification function and a preparation method of the building decoration material. The building decoration material is composed of the following components in parts by weight: 1-20 parts of a formaldehyde scavenger, 100 parts of a base material, 0.5-1 part of modified starch, 1-1.5 parts of a binder, 0.6-1 part of lignocellulose, 0.01-0.1 part of a foaming agent and 65-75 parts of water, wherein the formaldehyde scavenger is composed of the following componentsin parts by weight: 2-10 parts of polyvinylpyrrolidone, 1-6 parts of a water-soluble polymer compound, 4-42 parts of a chiral amino alcohol, 1-7 parts of titanium dioxide, 1-7 parts of tin dioxide, 1-7 parts of silicon dioxide, 2-6 parts of magnesium oxide, 1-13 parts of activated carbon, 1-9 parts of calcium chloride and 1-13 parts of a soluble weak acid salt. The building decoration material provided by the invention can quickly, stably, and highly efficiently purify formaldehyde, and is suitable for large-scale promotion and application.

Description

technical field [0001] The invention belongs to the technical field of air purification, and relates to a building decoration material with formaldehyde purification function and a preparation method thereof. Background technique [0002] Formaldehyde is a protoplasmic toxic substance that can combine with amino groups in proteins to form formylated proteins. The impact of formaldehyde on human health includes abnormal sense of smell, respiratory tract irritation, abnormal lung function, central nervous system impact, abnormal immune function, and damage to genetic material in cells. The harm is serious and cannot be ignored. Therefore, my country's standard stipulates that the concentration of formaldehyde in indoor air should not be greater than 0.08mg / m 3 , and the concentration of formaldehyde in the air of public places shall not exceed 0.12mg / m 3 . [0003] At present, indoor formaldehyde pollution has become the most important indoor air pollution problem in my cou...
