The so-called rubber formula design is based on the performance requirements of rubber products and the process conditions in the manufacturing process. Through testing, optimization, identification, and rational selection of raw materials, the amount and ratio of various raw materials are determined.
It is well known that a single body material, whether natural rubber or synthetic rubber, is difficult to process into a product that meets performance requirements without proper B-binding. Any rubber product has its specific performance requirements (use performance and process performance), and long-term practice has shown that ‘only by formulating the raw rubber and the four compounding agents reasonably combined to form a multi-component system’ and Each component plays a certain role, and finally the system effect of the entire formulation system can be fully utilized to meet the requirements of use and processing.
The first section of rubber formula design overview
First, the content of rubber formula design
Rubber formulation design is a key part of the rubber product production process – it has a decisive impact on product quality, processing performance and cost. The content of the rubber formula design should include:
1 Determine the main performance indicators of vulcanizates that meet the performance requirements of the products and the range of values ??of these performance indicators;
2 to determine the process performance of the compounds necessary for existing production equipment and manufacturing processes and the range of these performance indicators;
3 Select the main material and compounding agent that can achieve the specified properties of the rubber compound and vulcanizate’ and determine the dosage and ratio.
Second, the principle of rubber formula design
With the rapid development of science and technology, the modern rubber formula design process is not a simple experience combination of various raw materials, nor is it the “prescription of medicine” of Chinese ancestral Chinese medicine, but on the basis of fully grasping various cooperation principles, application The basic theories of molecular materials, using the advanced technology and theory of various related disciplines, to understand the relationship between the structure and properties of polymer materials, so as to play the system effect of the entire formulation system, determine the optimal dosage and ratio of various raw materials.
The principles of rubber formulation design can be summarized as follows.
1 vulcanized rubber has the specified technical properties to achieve high quality products;
2 The processing technology is good in the rubber and product manufacturing process, which can make the product reach high yield;
3 Under the premise of not reducing the quality, reduce the cost of rubber compounding, and increase the energy consumption in the manufacturing process to improve the economic benefits of the enterprise;
