Diatomite coating capable of adsorbing formaldehyde and preparation method

Abstract

The invention discloses a diatomite coating capable of adsorbing formaldehyde and a preparation method. The diatomite coating comprises, by weight, 25-50 parts of diatomite, 2-5 parts of glass fiber,0.5-2.0 parts of dispersant, 20-30 parts of adhesive, 5-35 parts of nanoscale titanium dioxide, 5-35 parts of nanoscale zinc oxide and 2-5 parts of plant fiber, weight percent of SiO2 contained in diatomite is greater than or equal to 90%, and grain size of diatomite is 60-150 meshes. The diatomite material has large specific surface area and high adsorbability, various nano materials which are mixed are combined, the glass fiber improves light reflection, and the plant fiber is added to enhance adsorption of humidity and formaldehyde, so that indoor air pollutants are reduced substantially, and indoor environment is improved actively; diatomite has through pore diameter, thereby having extremely high heat insulativity and sound absorptivity; diatomite has effects of eliminating static electricity in indoor air and killing parasites and microorganisms, can prevent molding and color-changing of wall surfaces and obviously reduce indoor peculiar smell.

Description

technical field [0001] The invention relates to the field of nanometer materials, in particular to a diatomite coating for absorbing formaldehyde and a preparation method thereof. Background technique [0002] Adsorbing formaldehyde paint is a popular material for interior decoration materials in recent years. The development of the economy has promoted the improvement of people's awareness of environmental protection, and the environmental quality has attracted widespread attention. The successful research and development of anti-formaldehyde coatings has effectively relieved consumers' confusion and troubles in the selection of interior decoration materials. While the use of a large number of decoration materials improves the quality of life of consumers, it also causes the continuous deterioration of indoor air quality. The harm to the human body, especially the harm to the elderly, children and pregnant women with weak resistance, has become a hot issue of concern . An...

Problems solved by technology

[0006] The present invention proposes a diatomite coating for absorbing formaldehyde and its preparation method. Aiming at the problem of low performance of the current inner wall diatomite materials in decomposing formaldehyde and other harmful substances, a new type of environmentally friendly diatomite material has been developed. The algae earth material is composed of pure natural materials and does not contain any harmful substances to the human body. It completely solves the harm of indoor environmental pollution to the occupants, and at the same time creates a primitive, simple and natural living environment for us; and in Strong effect on adsorption, decomposition and sterilizing functions
