【The latex product industry is a branch of the rubber industry and an important part of the rubber industry. In recent years, with the development of the global economy and the improvement of people’s material and cultural living standards, and the further development of medical and health services, the demand for medical latex products will continue to increase, and the amount of accelerators in its raw materials will also increase rapidly. 】
1. Medical latex products include
Medical gloves, latex silk or latex tapes on medical products, medical rubber plugs, medical latex tubes, etc. 72% of medical gloves are nitrile and latex gloves, the global nitrile and latex gloves, and nitrile gloves are used to avoid latex allergy, With the advantages of good elasticity and stable supply of raw materials, the proportion of use in the medical field has gradually increased.
2. Commonly used accelerators
Accelerator ZDEC (ZDC, EZ), ZDBC (BZ), ZMBT (MZ) is one of the common raw materials for medical latex products, and it is also one of the few rubber auxiliaries used in medical latex products with a large amount of products!
3. Introduction of commonly used accelerator product information
ZDEC (ZDC, EZ), zinc diethyldithiocarbamate, CAS number: 14324-55-1.
ZDBC (BZ), zinc dibutyldithiocarbamate, CAS number: 136-23-2.
ZMBT (MZ), zinc 2-mercaptobenzothiazole, CAS number: 155-04-4.
Accelerator ZDEC is a super accelerator for natural rubber and various synthetic rubbers. It is a representative variety of zinc dithiocarbamate salts. It is also a general accelerator for latex and is also used as a water-insoluble accelerator for latex. The stability of the latex has little effect. When used as the second accelerator of the thiazole accelerator in the latex, the obtained product has good aging performance. It is suitable for white and bright-colored products, transparent products, mainly used in the manufacture of medical products, adhesive tapes and self-vulcanizing products.
Accelerator ZDBC is a super accelerator for natural rubber, synthetic rubber and latex. It is commonly used in low-temperature vulcanization glue, and the vulcanization speed is faster than ZDEC and ZDMC. The general dosage is 0.5-2 servings. The latex-containing this product can be used for a week without early vulcanization. It is a better activator for thiazole accelerators.
Accelerator ZMBT, suitable for NR, IR, BR, SBR, NBR, EPDM and latex. It has mild activity in latex systems and is usually used in combination with super-accelerators. The critical temperature of vulcanization is higher (138℃). It is not easy to produce early vulcanization, and the vulcanization flatness is wide. It is suitable for latex systems and has the function of adjusting the viscosity of the system.
