Problems solved by technology

There are also a few manufacturers that produce bamboo charcoal interior wall putty powder. As we all know, bamboo charcoal is pure natural, has many pores, and has super adsorption capacity. However, when the pores of bamboo charcoal reach saturation, it cannot continue to adsorb, and bamboo charcoal cannot decompose formaldehyde.
At the same time, with the volatilization of moisture on the surface of bamboo charcoal pores, the adsorbed formaldehyde may volatilize into the air again, causing secondary pollution

Abstract

The invention provides bamboo charcoal anti-formaldehyde interior wall putty powder, which is prepared from the following components in percentage by mass: 54% of ground calcium carbonate powder, 20%of ash calcium powder, 20% of white cement, 4% of bamboo charcoal powder, 1.5% of an anti-formaldehyde air purifying agent, 0.4% of hydroxypropyl methyl cellulose and 0.1% of ultramarine. According tothe bamboo charcoal anti-formaldehyde interior wall putty powder, bamboo charcoal powder is added, and is high in porosity and large in surface area, and the molecular structure of carbon is stable,so that the formaldehyde adsorption performance is high; and the requirement on the filling performance of the traditional interior wall putty powder is met, formaldehyde can be adsorbed and re-decomposed, and indoor air is thoroughly purified.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a bamboo charcoal anti-formaldehyde interior wall putty powder and a preparation method thereof. Background technique [0002] It is very common for formaldehyde to exceed the standard after decoration, and it is also a very troublesome problem for many families. Formaldehyde mainly comes from artificial boards, adhesives used in furniture and decoration, and synthetic fabrics such as carpets. Excessive concentrations can cause nausea, vomiting, coughing, chest tightness, asthma and even emphysema. Generally speaking, the sources of indoor formaldehyde come from the following aspects: [0003] 1. It is usually used for various types of wood-based panels for interior decoration: plywood, blockboard, medium density fiberboard and particle board and other wood-based panels. Because formaldehyde, a harmful gas, has strong adhesion, and also has the functions of strengthening the hardness of...
