Description
Technical field
Belong to indoor decorating wall covering field, be specifically related to how lovely unleaded child's wall covering of a excellent performance.
Background technology
Growing city and rural area, the health hazard of child is especially had become as the hot issue that society is of greatest concern by the harm of human health by room air pollution. The cognition degree that indoor environment is protected by people also rises rapidly. In the decoration of indoor, the pollution of benzene class material in the general common concern coating of people, formaldehyde is only the number one killer in household decoration in fact, it is present in coating and adhesive in a large number, and the harmful substance release period such as formaldehyde, benzene that exceeds standard in finishing material is 3��15 years, traditional mode is adopted to be difficult to clean off. At present, the research of bioscience man finds, starch gelatinization liquid has the clean function of odor of the anti-corrosive antibacterial function of excellence, superpower moisture retention, pH value regulating power and excellence, the functionalized chemical composition of tradition emulsion paint is replaced with it, as: formaldehyde (preservative), ammonia (pH adjusting agent) and propylene glycol (wetting agent) etc., what can be inherently eliminated traditional paint penetrating odor produces the source with a large amount of VOC; And give plant paint absorb, the function of decomposing formaldehyde, allow people really use natural tasteless, novel plant paint product that high in environmental protection is safe, help people to realize the life dream of back to nature.
Summary of the invention
It is an object of the invention to utilize starch natural, resourceful thus providing how lovely unleaded child's wall covering of a kind of superior performance.
