The rapid development of science and technology, industrial modernization and the urban population is concentrated, with increasingly serious of environmental pollution, especially chemical Wuzhiwuran cause of and ecological crises, Yi Ying Xiang economic and social development as important factors.
Rapid development of industrial adhesives provide glue stick the community with many new types of plastic, but also to the environment of the new pollution problems. The function and application of adhesives has been widely recognized, and adhesive environmental issues are often neglected by people. However, environmental awareness and increasing health consciousness of today, on the adhesive requirements of environmental protection will become more stringent, the more important to protect the environment, producers should be pushing environmental and green adhesive and the users can use on non-toxic harmless desire adhesive. Therefore, it is necessary to understand the environmental problems adhesive.
Adhesives environmental problem is pollution of the environment and human health hazards, this is because the adhesive of harmful substances such as volatile organic compounds, toxic curing agents, plasticizers, diluents and other additives, harmful fillers and so caused.
Many adhesives are there different degrees of potential environmental pollution factors, only a clear understanding of which types of contaminants and hazards in order to try to eliminate and prevent. Adhesives hazardous substances mainly benzene, toluene, formaldehyde, methanol, styrene, chloroform, carbon tetrachloride, 1,2 a-dichloroethane, toluene diisocyanate, phenylene diamine, cresol phosphate ester, ethylenediamine, dimethyl aniline, antioxidant D, coal tar, asbestos powder, quartz powder. Environmental protection is to ensure sustained economic development in the 21st century and human health the key to survival. The environmental impact of industrial adhesives great responsibility to take effective measures as early as possible is a wise move. First need to change the traditional concepts, not only look to the local interests at the expense of the ecological environment; not only economic benefits for the time being, while the cost of sacrificing the environment, adhesive industry in the pursuit of economic benefit, should pay attention to the community efficiency and environmental benefits, environmental protection and make new contributions.
In order to avoid environmental pollution and ecological damage, the development of low-pollution or pollution-free environment-friendly adhesive is imperative. The so-called environmentally friendly green adhesive means no pollution, no poison on the human body, consistent with "environmental protection, health, safety," the three requirements of the adhesive.
To meet the social and environmental reasons, the adhesive should speed up the replacement of species, its development is water-based, solid-based, solvent-based, low toxicity of.
Solid-based adhesive is to use solid form, such as hot melt adhesive, hot melt pressure sensitive adhesive, water soluble powder glue, glue stick reactive, solid adhesive rod such office, in the coating and bonding process are non-volatile release, no environmental pollution.
Use of powdered rubber respected abroad, with stable performance, and no environment pollution. U.S. CP adhesive produced a urea formaldehyde resin powder, itself contains a curing agent and filler, odorless, no pollution, no poison, used as an excellent general-purpose wood adhesive. China has been the emergence of a new type of high-strength high-quality powder adhesive - strong state house powder (4), mixed with water into polymer dispersions, has outstanding adhesion, water resistance and resistance to aging. U.S. production - the kind of widely used epoxy glue stick, in the emergency repair, plugging very convenient.
Adhesives are new areas of fine chemical products, in the rapid development, has brought the issue of environmental pollution and health hazards, has aroused extensive attention to the environment and takes must not environment and wasting resources for the economic cost of Er Huan Qu temporary growth.
Aromatic solvent used in adhesives, chlorinated solvents, aromatic amine curing agent, styrene, vinyl chloride, formaldehyde, methanol, asbestos powder can cause environmental pollution and harm the human body. To prevent pollution, protect the environment, harm reduction, promoting development, production and use of adhesive must be environmental awareness, the development of water-based, solvent-based, solid-based, low toxicity and so environmentally friendly green adhesive, which is the direction.
