Because the components of the adhesive or the chemicals of the solvent are mostly organic chemicals, it is very harmful to the environment and the health of workers. It also affects the living environment, and the occurrence of indoor syndrome may be related to volatile organic compounds (VOC) such as formaldehyde, toluene, xylene or plasticizer. The impact on human health is:
1, dermatosis
Contact dermatitis caused by exposure to epoxy resin, n-hexane, toluene and vinyl chloride; Workers exposed to chloroprene rubber disappeared after exposure to skin pigment; Contact with glue containing epichlorohydrin (such as epoxy resin glue) will cause skin blistering.
Step 2 stimulate
Glue or steam containing epichlorohydrin, chlorinated solvent, toluene or xylene irritates eyes; Toluene, trichloroethylene or xylene irritates the mouth, throat and nasal cavity; N-hexane vapor stimulates respiratory tract.
3. Lung diseases
Contact with some fine dust or fibers of bonded inorganic insulating materials may cause pneumoconiosis; Long-term or inhalation of high-concentration mixed aromatic solvents and gasoline vapor may cause pulmonary edema; Inhalation of liquid benzene or xylene will increase the chances of pulmonary edema, chemical local acute pneumonia and bleeding.
4. The influence of nervous system
Inhalation of acrylonitrile, cyclohexane, toluene, xylene, 1, 1, 1- trichloroethane and trichloroethylene will inhibit the central nervous system and may cause headache, dizziness, dyskinesia, numbness and coma. N-hexane can cause polyneuropathy.
Extended data:
Adhesives refer to substances that bind materials such as paper, cloth, leather, wood, metal, glass, rubber or plastic together according to prescribed procedures.
With the development of science and technology, adhesive is increasingly replacing mechanical connection, which provides an effective way to simplify technology, save energy, reduce costs and improve economic benefits for various industries.
At present, the application fields of adhesives in China are constantly expanding, mainly from wood processing, construction and packaging industries to clothing, light industry, machinery manufacturing, aerospace, electronic appliances, advertising, transportation, medical and health care, post and telecommunications, warehouses and other fields, and it has become an indispensable and important chemical product in the national economy and people's lives.
There are many kinds of adhesives, which are divided into polymer, cellulose and protein (natural) according to their chemical composition and properties. Polymers can be divided into thermosetting adhesives, thermoplastic adhesives and rubber adhesives. Thermosetting adhesives include epoxy adhesives, phenolic adhesives, urea-formaldehyde adhesives and melamine-formaldehyde adhesives.
Thermoplastic adhesives include polyvinyl acetate emulsion and other resin adhesives. Cellulose can be divided into nitrocellulose and cellulose acetate. Protein (natural) can be divided into animal glue, casein glue, blood glue and vegetable protein glue.
