Description
Technical field
The present invention relates to a kind of wall paint, relate to fungi-proofing water-soluble environment protective type nano active charcoal wall paint of a kind of mildew-resistant and preparation method thereof specifically, belong to chemical industry wall paint technical field.
Background technology
A large amount of chemical that use such as referring to various buildings materials and finishing material discharge in the fitment process pollution and sterilant, reodorant, perfume compound are polluted in house decoration, the pollution that indoor environment is caused.People have accounted for 80～90% of whole day in the time of indoor study, work and life; " room air pollution " paid attention to by increasing people; and wall paint to pollute be the arch-criminal of indoor environmental pollution, the material that is coated on the fine bonding of body surface and other materials and forms whole and tough and tensile protective membrane is called wall paint.Be identical concept at architectural wall paint and paint.Wall paint in the market mainly is divided into water-based wall paint and solvent-borne type wall paint.Just can detect more than 50 kind of organism such as a large amount of benzene, toluene, ethylbenzene, dimethylbenzene, acetone, N-BUTYL ACETATE, acetaldehyde, butanols, formic acid in the space air of brushing wall paint, produce organic solvent volatile matter (voc) contaminate environment.The contained above-mentioned organic volatile of traditional solvent-borne type wall paint can damage people's respiratory system, hematopoietic function, immunity system, even causes the disease of aspects such as some heredity.
Because to environmental protection and the attention of health at home, the water-based wall paint has progressively replaced conventional solvent type wall paint, because the technology content of water-based wall paint is higher, most domestic manufacturers production difficulty is bigger, and the solvent borne wall paint is still propagated its belief on a large scale, and accounts for absolute main flow.People were placed on certain position absorbing formaldehyde to the charcoal bag before gac had powerful adsorption function, but were limited in scope after all, saturated just can not absorption afterwards, become source of pollution, and how to be the important directions of studying at present fast and effectively with regeneration of activated carbon.
In addition, to southern a lot of cities, always had plum rain season in common 1 year, at this moment, there was dampness in the air, and often continuous many days a run of wet weather grows multiple microorganism easily in the air, and therefore wall also frequent and mouldy, even the mildew spot, ten minutes influences attractive in appearance, and is easy to generate mouldy taste, people's health and body and mind are easy to generate bad influence, how guarantee that it is the problem that this type of lacquer wants emphasis to solve that the wall paint environmental protection characteristic can play the fungi-proofing effect of good mildew-resistant again.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned the deficiencies in the prior art, fungi-proofing water-soluble environment protective type nano active charcoal wall paint of a kind of mildew-resistant and preparation method thereof is provided, the nonpoisonous and tasteless poisonous chemical organic solvent of routine that do not contain of water-soluble environment protective type nano active charcoal wall paint that this mildew-resistant is fungi-proofing, do not add poisonous wall paint sanitas, be conducive to environmental requirement, and can play the fungi-proofing effect of good mildew-resistant.
