Nowadays, people's life is more about quality, and home is a warm and comfortable place for everyone to enjoy. However, many decoration companies are not very satisfied in the choice of paint in order to save costs. Therefore, in response to increasingly stringent environmental regulations, water-dispersible polyisocyanates have shown importance in various application fields in recent years. At present, water-dispersible polyisocyanates in most applications are modified by polyethers to achieve non-ionic hydrophilic modification. Although this type of hydrophilic modified polyisocyanate has been widely recognized in the market in most applications, it also has certain shortcomings, such as its high viscosity, which requires considerable shear force to be uniformly distributed during the construction process. Introduced into the aqueous medium. In order to avoid the above shortcomings, this also gives CAPS an excellent opportunity. Let it find its place in the new paint.
Ion-modified groups include carboxyl, sulfuric acid, hydroxyl, hydroxysulfonic acid, etc., but there are still certain defects. For example, carboxyl modified polymers are prone to gelation, and the color of hydroxysulfonic acid modified products is obvious. Huang et al. Later, Bayer reported 3-(cyclohexylamino)-propanesulfonic acid (CAPS) modified polyisocyanate in its patent CN1429240A. It was found that CAPS-modified polyisocyanate can achieve fine dispersion in water and the product is stored stable. CAPS-modified polyisocyanates show certain advantages over other ionic or non-ionic modified products.
1. 3-(Cyclohexylamino)-1-propane sulfonic acid (CAPS) reacts with aliphatic polyisocyanate (the former is zwitterionic sulfamate) under mild conditions and the presence of a tertiary amine neutralizer to produce Sulfonic acid urea derivatives are excellent emulsifiers. Regardless of salt-forming groups, CAPS-modified polyisocyanates have good storage stability and are not turbid. Even when they contain less sulfonate groups, a well-dispersed emulsion can be obtained in water. A series of ionized modified polyisocyanates can be obtained, which can be used in various environmentally friendly high-quality water-based two-component polyurethane coatings. These coatings are completely comparable to general solvent-based coatings in terms of dryness, curing and chemical resistance. The new regulations require further reduction of VOC (Volatile Organic Compounds). In the future, the amount of these crosslinking agents will be greatly increased. Compared with solvent-based coatings, they will not cause the quality of the paint film to decrease.
Blocked water-dispersible polyisocyanate curing agent: Blocked water-dispersible polyisocyanate curing agent is a hydrophilic modification of the blocked polyisocyanate curing agent, so that this type of product can be dispersed in a water-based resin system. Under high temperature baking conditions, the blocking agent will unblock from the system, releasing isocyanate groups, and the isocyanate groups will react with the hydroxyl groups. To
The sealed water-dispersible polyisocyanate curing agent is mainly used as a crosslinking agent for high-temperature baking systems. At present, the main application is in the middle coating of the original car paint. In addition, there are some applications in the water-based industrial paint. The blocked water-dispersible polyisocyanate curing agent can also be used with the melamine curing agent. The melamine curing agent is used to reduce costs, and the blocked water-dispersible polyisocyanate curing agent can improve performance.
In addition to being used in new materials and coatings, CAPS is also used as a biological buffer, used in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits; enzymatic chemistry and HPLC separation of alkaline drugs buffer.
