Environment-friendly and energy-saving type diatom ooze coating and preparation method thereof

Abstract

The invention discloses an environment-friendly and energy-saving type diatom ooze coating. The coating comprises raw materials as follows: ash calcium powder, titanium dioxide, quartz sand, a thermal-insulating and reflective function material, nano-titanium dioxide, diatomite, hydroxypropyl methyl cellulose, sodium carboxymethyl starch, EVA (ethylene / vinyl acetate) glue powder, color powder and a mildew preventive. The environment-friendly and energy-saving type diatom ooze coating has excellent reflecting and emitting functions and formaldehyde decomposition capacity through application of the thermal-insulating and reflective function material and the nano-titanium dioxide, and the reflectivity, the hemisphere emissivity and the formaldehyde decomposition rate reach 0.85, 0.89 and 85% or higher respectively; compared with existing diatom ooze coatings, the environment-friendly and energy-saving type diatom ooze coating can reduce the room temperature by 4-5 DEG C, saves 40% of energy and solves the problem of secondary pollution and the like caused by re-releasing of formaldehyde and the like in a dry environment. The invention further discloses a preparation method of the environment-friendly and energy-saving type diatom ooze coating.

Description

Technical field [0001] The invention involves the field of decoration and decoration materials, which specifically involves an environmentally friendly energy -saving diatom mud coating and its preparation methods, which are the field of energy -saving coatings. Background technique [0002] As the industry knows, in recent years, many new indoor and outdoor decoration materials with diatom soil as raw materials are increasingly favored by consumers at home and abroad.As a natural material, diatomic soil does not contain harmful chemicals. In addition to the characteristics of non -combustible, sound insulation, waterproof, light weight, and heat insulation, it also has the functions of dehumidification, deodorization, absorbing formaldehyde, and decomposing formaldehyde purification indoor air.Combined with the construction process, it can also form a decorative effect with different forms and strong texture. It is an excellent environmentally friendly indoor and outdoor decorat...

AI Technical Summary

Problems solved by technology

As a natural material, diatomaceous earth does not contain harmful chemicals. In addition to its characteristics of non-combustibility, sound insulation, waterproof, light weight and heat insulation, it also has the functions of dehumidification, deodorization, absorption of formaldehyde, and decomposition of formaldehyde to purify indoor air. Combined with the construction technology, it can also form decorative effects with different shapes and strong textures. It is an excellent environmental-friendly indoor and outdoor decoration material; It is a pity that thick decorative coatings do not make full use of the characteristics of thick coatings and endow them with energy-saving functions.
