ZDA is a metal salt of unsaturated carboxylic acid (Unsaturated Carboxylic Salt), used as a crosslinking agent for peroxide vulcanized rubber. Its specific chemical composition is anhydrous zinc acrylate. ZDA can form an "ionic" cross-linked structure in peroxide-vulcanized rubber. This "ionic" bond has good heat resistance and can slide along the direction of the carbon-hydrocarbon chain and can be restored. This makes this vulcanizing agent have the advantages of peroxide and sulfur vulcanizing agents. It can impart high tensile strength and high tear strength to rubber products, while also significantly improving the thermal aging properties of the products. Specifically, ZDA can significantly improve and improve the adhesion of peroxide vulcaniz It is a more economical way to improve the performance of peroxide vulcanized rubber. Under the condition of achieving the same or even better performance, the use cost is lower than the use cost of some commonly used vulcanizing agents such as HVA-2 (PDM).
We have two specifications of zinc acrylate, one for the rubber industry and the other for the manufacture of golf balls.
Used in golf
Zinc acrylate has been used as a polybutadiene rubber for vulcanizing the core part of golf balls for many years. Polybutadiene crosslinked with zinc acrylate is a very hard rubber with high compression resistance and excellent resilience. Zinc salt has been proven to be the most effective salt, and it is now widely used to make golf balls. Zinc acrylate can be quickly compounded with various rubbers, not only has strong oil and solvent resistance, but also shows very good thermal stability. Many unique characteristics are formed due to the interaction between the zinc cation and the carboxylic anion. Metal cations, especially zinc cations, are generally believed to be cross-linked through ionic bonds to improve the tensile properties of metal-neutral ionic bond polymers. At the same time, this product can be used as a vulcanizing agent for rubber, a crosslinking agent for artificial marble, and a heat-resistant additive. It has the properties of acid and alkali resistance, oil resistance, corrosion resistance and high temperature resistance. Combining with rubber can obtain salt-resistant cross-linking bonds, improve rubber strength, and improve low-temperature performance. In addition, it can also improve the elasticity, increase the tear resistance, reduce the white carbon black, and strengthen the compression permanent deflection of the rubber.
Adding 3-6 parts of zinc acrylate to the formula of the EPDM rubber insulation layer significantly improves the bonding performance of the metal and EPDM rubber insulation layer. Zinc acrylate has little effect on the processing fluidity of the rubber compound. And with the increase of the dosage, the crosslinking effect of the system increases. In the presence of the peroxide vulcanization system, the zinc acrylate has a significant reinforcing effect on the rubber compound. With the increase of the dosage, the tensile strength of the EPDM vulcanizate, The tear strength and hardness are improved, and the elongation at break is reduced.
Used in rubber
Applicable rubber: hydrogenated nitrile rubber (HNBR), butadiene rubber (BR), ethylene propylene diene rubber (EPDM), natural rubber (NR), styrene butadiene rubber (SBR), chlorinated polyethylene (CPE), Peroxide cross-linked rubber (elastomer) such as silicone rubber and fluorine rubber.
1. Peroxide vulcanized rubber products with good heat resistance, oil resistance, ozone resistance, load-bearing capacity, dynamic stability, abrasion resistance and cord bonding strength are required, such as rubber rollers, timing belts, and V-belts , Seals, belts, hoses, engine brackets and other rubber parts under the hood.
2. Used in EPDM, natural rubber, butyl rubber, styrene butadiene rubber and other automotive sealants, it can significantly improve the adhesion of the sealant to steel, glass, coatings and even oily steel and the heat resistance of the sealant And modulus.
3. It is used in the rubber sheath of EPDM and other cables to improve heat resistance and tensile and tear strength.
