Technical field
The present invention relates to a kind of interior wall coating, and in particular to a kind of antibiotic paint for efficiently removing formaldehyde and its preparation side
Method.
Background technology
Formaldehyde is a kind of colourless, there is the gas of intense stimulus type smell.Soluble in water, alcohol and ether.The World Health Organization exists
No. 153 publication identification of issue in 2004：Formaldehyde is carcinogenic and cause deformed material.Formaldehyde is generally acknowledged allergen,
One of it is one of potential strong mutagen, and cause the hazards of child's leukaemia.According to the country medical journal and
Pertinent literature reports that harm of the indoor formaldehyde to health can be summarized as stimulation, toxic action and carcinogenesis.
Due to growth in the living standard, increasing people likes being fitted up in its house, but enters luggage in house
When repairing, come from the artificial boards such as the glued board used during interior decoration, core-board, medium density fibre board (MDF) and particieboard, family
Tool, fabrics furniture, kitchen furniture can all produce the health that formaldehyde endangers people, while it is harmful also to produce benzene, heavy metal, VOC etc.
Material.
Therefore, there has been proposed various methods, such as the sprinkling of plant absorption method, cleanser, charcoal absorption etc..
But although the above method can clear up formaldehyde, many deficiencies are still suffered from, for example, plant absorption method purification efficiency is low, effect
Unobvious；Cleanser spray effect is not lasting, and some cleansers simply cover smell, can not eliminate formaldehyde.Activated carbon
The suction-operated of PARA FORMALDEHYDE PRILLS(91,95) is obvious, but needs often to change, it is impossible to the formaldehyde in fully erased air.
Although being developed the latex paint formulation of various anti-formaldehyde at present, it is bad to still suffer from discomposing effect,
The technical problems such as decomposition efficiency is low, anti-microbial property is poor.
The content of the invention
The present invention is bad for existing anti-methanal paint discomposing effect, and the technologies such as decomposition efficiency is low, anti-microbial property is poor are asked
