Crosslinking agent for nitrogen propyl compound coatings
Water - based coating is gradually replacing solvent - based coating, and nitrogen - propionidine coating crosslinking agent is indispensable in waterborne coatings.
On the basis of the crosslinking agent of the nitrogen propionidine, the properties of the azepam coatings were investigated through the application of the application.
Water - based coatings are used as solvents or coatings for dispersing medium, including water-soluble coatings, water-diluting coatings and water-dispersible coatings.At the same time, because of n propyl organism functional group special molecular structure, make n propyl organism crosslinking agent has good solubility in water and oil soluble at the same time, the polyacrylate, polyethylene, polyurethane, polystyrene, protein and polysaccharide, which was good for the polymer products such as crosslinking and crosslinking performance.
Water - based paint USES water as a dispersing medium, with no fire hazard, low production cost, no organic volatiles, water dilution and cleaning.
Apply to the following areas:
(1) significantly improve the resistance to water resistance, abrasion resistance and high temperature resistance of leather coatings;
(2) it can significantly improve its water resistance, wear resistance and chemical resistance when used in waterborne parquet wood paint, water-based plastic paint and water-based metallic flash paint;
(3) significantly improve water resistance and washing resistance of water-based printing ink;
(4) to improve water resistance, wash and relatively wide requirements of waterborne printing coatings, which meet the requirements of green production.The coating is more and more widely, the application scope of all the external walls of paint, wood paint, automobile paint have corresponding water-based paint products, such as visible water-based paint will gradually replace solvent-based coating.
People found in the application, the water-based coating resin in introducing hydrophilic group, often makes the film gloss, water resistance, solvent resistance and stain resistance is poorer, coating hardness and mechanical properties such as tensile strength is not equivalent to that of solvent-based paint.

In order to make up for the deficiency of, usually adding cross-linking agent, crosslinking modification of waterborne coatings, modified resin crosslinked network structure can be formed, when the water resistance and solvent resistance of the coating performance is greatly improved, at the same time reduces the coating of temperature sensitivity, solved the problem of the resin coating hot sticky cold short.At present, the study on water - based coatings is more mature and effective at room temperature resistance and high temperature resistance.
(5) bonding agent for solid propellant in military products.
We on the basis of investigating the synthesis of a series of n propyl organism compounds, through the applied experiment of the textile printing and dyeing, leather finishing, caigang paint, wood coatings, and other industries with crosslinking performance in water-based coatings, and the testing results of the corresponding conclusions, n propyl organism kind of crosslinking agent on the application and development of waterborne coating provides an important ideas and reference.
Crosslinking agent is the crosslinking agent of azepam.There is a large tension in the structure of n-propionidine ring in the crosslinking agent of nitrogen prodiazine, and the activity is higher, which can form an independent network structure with the carboxyl and hydroxyl reaction at room temperature to achieve the purpose of the crosslinking.
Experimental raw materials: isopropanolamine, sulfuric acid, sodium hydroxide, analytical class, market products;
TMPTA (trimethylolpropane three acrylate), TMPTEOTA [oxidation trimethylolpropane three (3) b acrylate], TMPNEOTA [(9) ethylene oxidation trimethylolpropane three acrylate], three ester content is more than 80%, the sold goods;Dichloroethane, market products.
Stay warm for 2h and stop reaction.Reaction temperature down to room temperature after bottle, add 200 g50 % NaOH solution, at 110 ℃ for atmospheric distillation, collect ￣ E fractions from 70 to 90, is the aqueous solution of methyl n propyl organism.
