Background technology
House fitting pollution refers to the pollution and a large amount of chemical used such as sterilant, reodorant, perfume compound that in fitment process, various buildings material and finishing material discharge, to the pollution that indoor environment causes.People have accounted for 80 ~ 90% of whole day in the time of indoor study, work and life; " room air pollution " is paid attention to by increasing people; and coating pollution is the arch-criminal of indoor environmental pollution, is coated on body surface and other materials and binds very well and the material forming whole and tough and tensile protective membrane is called coating.Identical concept at architectural coating and paint.Coating in the market is mainly divided into water-borne coatings and solvent based coating.50 gas chromatographies such as a large amount of benzene, toluene, ethylbenzene, dimethylbenzene, acetone, N-BUTYL ACETATE, acetaldehyde, butanols, formic acid can be detected in the space air of just brushing paint, produce organic solvent volatile matter (voc) contaminate environment.Above-mentioned organic volatile contained by traditional solvent based coating can damage respiratory system, hematopoietic function, the immunity system of people, even causes the disease of the aspects such as some heredity.
Due to the attention to environmental protection and house health, water-borne coatings progressively instead of traditional solvent-borne coating, and because the technology content of water-borne coatings is higher, most domestic manufacturers production difficulty is comparatively large, and solvent reducible coatings is still propagated its belief on a large scale, and accounts for absolute main flow.
Be reduced to minimum level for the external world is encroached on the loss caused, guarantee the tolerance that the surface after sprayed coating is attacked to external world, add anticorrosion as far as possible in coating and be imperative.The sanitas added in coating conventional at present comprises organic mercury, lead, organotin, phenol, formaldehyde or dichromate, but due to large to person poultry toxicity, environmental pollution is serious, and Systems in Certain Developed Countries has forbidden that it uses.
