Landing natural rubber is a new type of raw material commonly used in the rubber products industry to replace natural rubber, and compared with the use of natural rubber for the production of foamed rubber pads, it can not only reduce the dependence on natural rubber resources, but also reduce the cost by about 20-35%. When using floor-standing natural rubber to produce high-quality foamed rubber mats, special attention needs to be paid to three key factors: practical formulation, vulcanization formulation and compounding process.
First of all, the practical formula is one of the key factors affecting the performance of foamed rubber pads. In practical formulations, the choice of additives and fillers has a significant impact on the performance and cost of the product. For example, suitable blowing agents and crosslinkers can be selected to control the foaming and vulcanization processes to achieve the desired physical properties. In addition, the choice of filler is also very important, which can improve the strength and abrasion resistance of the foamed rubber mat and reduce the cost. Therefore, in the practical formulation, it is necessary to reasonably select the type and amount of additives and fillers according to the product requirements and the needs of cost control.
Secondly, the vulcanized formula is one of the key factors affecting the quality of foamed rubber pads. The vulcanization properties and product requirements of natural rubber need to be reasonably considered in the vulcanization formulation. The choice of vulcanization temperature and time is very important, too high temperature and too long time will lead to incomplete vulcanization or excessive vulcanization, which will affect the physical properties of the foam rubber pad. At the same time, the selection of vulcanizing agents also needs to be reasonably matched according to the characteristics of natural rubber and product requirements. Therefore, it is necessary to select the appropriate vulcanization temperature, time and type of vulcanizing agent according to the specific situation to ensure the quality of the foamed rubber pad.
Finally, the compounding process is a key part of the preparation of foamed rubber pads. In the mixing process, it is necessary to pay attention to the dispersion and filling properties of the landed natural rubber. The dispersibility of natural rubber has an important impact on the uniformity and quality of rubber compounds, and poor dispersion will lead to uneven and degraded properties of rubber compounds. Therefore, in the mixing process, the appropriate mixing process and the dosage of additives can be adopted to improve the dispersion of natural rubber. In addition, the selection and addition of filler will also affect the filling performance of rubber compound, and reasonable filler selection and addition method can improve the filling effect of rubber compound, thereby improving the performance of foamed rubber pads.
The practical formula, vulcanization formula and rubber mixing process of the foamed rubber mat produced by the landing natural rubber are the key factors, which directly affect the finished product variety, and the foamed rubber mat production enterprises must pay special attention; In the future, Xiaobian will continue to share with you other rubbers (such as latex reclaimed rubber, tire reclaimed rubber) and the key points of formula design and production process.
