Used crosslinking agent for paint
The coating is a mixture composed of polymers and ingredients, and can be coated with new polymer materials that adhere to the continuous coating of the substrate surface.
Volatile organic compound (VOC) in coatings in the form of gaseous molecules in their production, construction, drying and curing film in the process of sending out into the air, not only cause the pollution of the environment to a certain extent, but also pose a threat to human health.
Countries around the world in order to protect the environment, also in order to protect the safety of human life on earth, formulated the relevant environmental protection laws and regulations limit the VOC content in the coating and emissions.
China for volatile organic compounds, such as toluene and xylene, soluble cadmium 10 kinds of interior decoration decorates material harmful material, made the mandatory safety standards and emission limits.
In recent years, China has further perfect the relevant laws and regulations of environmental protection, established a relatively perfect "China coating low pollution standards of national development of safety system", including the test method standard of harmful substances in the coating (such as VOC difference measurement, VOC gas chromatography determination method and the method for determination of the VOC in emulsioni paint, etc.) and paint in the harmful material set limit to product standards (such as solvent wood coatings in the external walls of harmful material set limit to and harmful material set limit to, etc.).
Is one of the important source of VOC coating dispersion medium which is the main material and film forming matter, in view of the shortcomings of organic solvent coating, water-based resin production technology progress and development is urgently needed, at the same time, waterborne coatings gradually replace the organic solvent coating prospect is bright.
Adding crosslinking agent to the pigment printing paste can improve the fastness of the adhesive. In the crosslinking adhesive, to modified melamine Helizarin Fixagent LT advisable, crosslinking agent can improve the adhesive on the pure cotton, synthetic fiber and blended fabric printing fastness, and formaldehyde content is low, but there are also using 6 hydroxy methyl methyl etherification melamine as cross-linking agent.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine packingļ¼ net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
In non self crosslinking binder, printing paste often join crosslinking agent EH, Acratix FH, the use of such crosslinking agent after curing adhesive film yellowing easily, can also add type powerful crosslinking agent crosslinker sac - 100, UN - 125 - f, using such crosslinking agent after curing adhesive film is not yellow.
Any coating that USES water as a solvent or as a dispersing medium can be called a water-based coating. Water-based coatings include water soluble coatings, water dilutive coatings, and water dispersible coatings (latex coatings) 3 kinds. Water soluble coatings based on water soluble resin as film forming matter, represented by polyvinyl alcohol and its various modification, there are water soluble alkyd resin, water soluble epoxy resin and inorganic polymer water-based resin, etc.
Water-based coating is environmentally friendly. Water-based coating from raw materials to production and the full life cycle of use, is conducive to the healthy development of environment. It not only replaces volatile organic solvents in the production process, but also reduces the consumption of cleaning solvent.
Production needs to consume fossil raw materials of organic solvent, the resource shortage of the present stage is a big challenge for resources, the emergence of waterborne coatings, solved this problem. At the same time, the cut of the solvent, greatly reducing the production and use process emissions of volatile organic compounds, in order to improve the atmosphere environment made a positive contribution.
Ma Chunqing etc compared the VOC emissions of different coating systems, the results show that the solvent in the coating + + one-component finishing varnish solvent paint "process system of VOC emissions of 120 g/m3, and" water-based coating + water-based paint, water-based varnish coat "process system of emissions is only 28 g/m3, reduce the emissions. Water-based paint, on the other hand, using only a small amount of low toxicity of ethanol and organic solvent, reduced the volume of organic solvent volatilization, greatly improving the workplace environment, conducive to the staff's health.
