Description
Technical field
The present invention relates to technical field of coatings more particularly to a kind of antibacterial environment protection coating and its preparation processes.
Background technique
Coating, in the entitled paint of Chinese tradition.So-called coating be coated in the body surface being protected or decorated, and
The continuous film of firm attachment can be formed with coated article, usually based on resin or oil or lotion, add or do not add face
Material, filler add corresponding additive, the thick liquid being formulated with organic solvent or water.Chinese paint industry is more authoritative " to be applied
Material technique " in be defined such that " coating is a kind of material, and this material can be coated in object with different construction technologies
Surface forms and adheres to securely, with some strength, continuous solid film.Formed in this way film common name film, also known as paint film or
Coating.Present paint is due to the reasons such as the surface tension of itself is excessive or dissolubility is bad, so that coating layer when brushing
Between attachment, in conjunction with bad, the morbid state phenomenon such as can generate pull-away, peelings, play drum, peeling.
Coating is all chemicals at present, in addition to releasing peculiar smell after coating, such as formaldehyde, VOC (volatile organic compounds), again
Metal, benzene etc. are exceeded then to generate outside a large amount of poison environment and human health, and virus and bacterium are always in living space
With and without place not, everybody physical and mental health is perplexed always and threatens in the presence of virus and bacteria to the extent of injury of human body, respectively
Kind has bacteria breed, such as Escherichia coli, staphylococcus aureus meeting through metope, the various furniture of coating painting brush such as paint etc.
Bacterium infection is caused to spread the disease.And existing coating and do not have effect antibiotic and sterilizing.Therefore, industry urgent need, which provides one kind, has
Antibacterial, sterilization coating.
The most effective approach of coating antibiosis mildew resistance is to add people to have antibacterial and antimildew function and can stablize in film to deposit
Substance, play antibacterial action.Traditional antibacterial mildew inhibitor, such as formaldehyde, heavy metallic salt, phenol, penta sodium pentachlorophenate, due to right
Environment and human body are toxic, have been forbidden to use.Coating obtains extensively with its excellent filming performance and to the friendly of environment
Using development is swift and violent.
The present invention is intended to provide a kind of coating, can be effectively prevented the growth and breeding of various bacteriums, and can kill
The various bacteriums on coating are fallen in, are a kind of are able to use in the coating of hospital, kitchen, toilet and various public places.
