Water based adhesive Water-based adhesive refers to the water-soluble polymer dissolved into appropriate concentration of aqueous solution, or insoluble polymer dispersed into micro-particles (emulsion) in water with the help of surfactant in the general term of adhesives;In simple terms, adhesives made of materials that can be dispersed or dissolved in water are aqueous adhesives and are often referred to as water-based adhesives. classification Water-based adhesives can be divided into the following categories: 1. Aqueous solution, such as starch or dextrin, cellulose and protein natural adhesives, polyvinyl alcohol, phenolic resin, urea-formaldehyde resin, melamine resin and other synthetic adhesives; 2. Emulsion or water dispersion, such as PVAc, EVA emulsion, polyacrylate emulsion, epoxy resin emulsion, butylbenzene, nitrile, neoprene latex, polyurethane emulsion, etc. 3. Aqueous dispersion, such as water-based reclaimed rubber or butyl rubber, etc. Application area Automobile industry: With the development of automobile industry, the relationship between automobile and adhesive is more and more close. Firstly, the "three leaks" (air leakage, rain leakage and dust leakage) of the car are solved, and the comfort of the whole car is improved. Secondly, it not only plays the role of heat insulation and vibration reduction, enhancement of automobile structure and interior and exterior decoration, but also simplifies the automobile manufacturing process, and plays a more and more important role in automobile energy saving and consumption reduction, lightweight and extension of service life. Therefore, the amount of adhesive on the car is increasing. Packaging industry: in our country's flexible packaging industry, the proportion of water-based adhesives is still relatively high. In the past, solve-based adhesives were used, but there are serious organic solvent volatilization and residue problems in solve-based adhesives, which not only pollutes the environment, but also has a variety of health and safety risks. Today, when the green wind swept through the whole packaging and printing industry, the industry turned its attention to more environmentally friendly water-based adhesives and solvless adhesives, especially the water-based adhesives gave high hopes. Construction industry: in the internal structure decoration, there are many building materials in the process of manufacturing and production also need to be used. At present, in order to solve the problems of pollution and the key to the human body, the construction field has gradually begun to use more environmentally friendly water-based adhesives. Обувная промышленность: с учетом требований политики защиты окружающей среды и здоровья и защиты окружающей среды, клей на основе ool из-за большого количества летучих растворителей, с сильным запахом, сенсибилизацией, загрязнением окружающей среды, токсичными компонентами и другими недостатками, нетоксичный, не загрязняющий окружающую...
