Granulation of rubber additives is the process of the final product of the additive production process. At present, the overall granulation level of rubber additives in China is not high, the development is not balanced, and the proportion of granulated products is low. The rubber additive granulation technology includes oil filling, dry granulation, wet granulation, melt granulation and carrier pre-dispersion granulation. You can choose according to the characteristics of the product and the needs of the user. Most of the accelerators can be selected from wet granulation or dry granulation. The anti-aging agents and processing rubber additives with low melting point and softening point are mostly melt-granulated. Most of the pre-dispersed granulations use polymers as carriers. Applicable to accelerators and raw materials including zinc oxide, white carbon black, sulfur yellow, etc.
Many additives companies in China have paid attention to the granulation technology. For example, the accelerator TMTD has fine dust and strong irritation. The Zhenjiang No. 2 Chemical Plant first adopted oil filling and process control technologies to achieve the dust-free TMDM. Tongling Organic Chemical Plant Hetai An Feida Chemical Co., Ltd. has successfully developed granulation products of antioxidant 4020, plasticizer A granulation products of Shandong Yanggu Huatai Chemical Company, and granulation products of processing aids such as dispersant of Yixing Kao Chemical. Representation.
The granulation of rubber additives is of great significance to additive factories and rubber processing plants, reducing product dust pollution, increasing the accuracy of batching in processing plants, and improving the physical properties of rubber compounds to ensure product quality. enhancement.
In addition, the formulation of rubber additives is one of the important gaps between China ’s rubber additives and foreign countries. The production capacity of China ’s rubber additives is relatively large. If the grade is not improved as soon as possible, the modified dosage form will not be able to squeeze into the international market. The listing of products of joint ventures and foreign-funded enterprises will also seriously impact the domestic market.
The 21st century is the century of environmental protection. The green industry has become the development direction of the world's industries. China's rubber additive industry must strengthen environmental awareness and vigorously promote clean production. In the principle of "energy saving, consumption reduction, pollution reduction, and efficiency enhancement," it is continuously promoted. Scientific and technological progress, to achieve sustainable development of the industry.
