Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an impact-resistant and wear-resistant rubber material. Background technique [0002] With the rapid development of the industrial field, traditional rubber materials can no longer meet the requirements of use. At present, inorganic powder minerals are often used to strengthen rubber materials. Ground calcium carbonate, as a commonly used powdered inorganic filler for rubber, has high chemical purity, high inertness, and is not easy to chemical Reaction, good thermal stability, no decomposition below 400°C, non-toxic, good dispersibility, etc., have been widely used for many years to solve various problems, and heavy calcium carbonate has been more and more widely used as a rubber filling material Application, heavy calcium carbonate is ground from natural carbonate minerals such as calcite, marble, and limestone. Adding heavy calcium carbonate to rubber can increase rubber volume...

[0002] With the rapid development of the industrial field, traditional rubber materials can no longer meet the requirements of use. At present, inorganic powder minerals are often used to strengthen rubber materials. Ground calcium carbonate, as a commonly used powdered inorganic filler for rubber, has high chemical purity, high inertness, and is not easy to chemical Reaction, good thermal stability, no decomposition below 400°C, non-toxic, good dispersibility, etc., have been widely used for many years to solve various problems, and heavy calcium carbonate has been more and more widely used as a rubber filling material Application, heavy calcium carbonate is ground from natural carbonate minerals such as calcite, marble, and limestone. Adding heavy calcium carbonate to rubber can increase rubber volume, reduce product cost, improve dimensional stability of rubber, and improve heat resistance However, because the surface of heavy calcium carbonate powder has a hydroxyl group with strong hydrophilicity, it is hydrophilic and oleophobic, which makes its affinity with rubber worse, and it is unevenly dispersed in rubber. With the increase of the filling amount, these shortcomings become more obvious. How to prepare a rubber material with good compatibility between materials, excellent mechanical properties and excellent reinforcing properties has become a technical problem that needs to be solved at present.
