High-reinforced high-mechanical capacity rubber material

Abstract

The invention discloses a high-reinforced high-mechanical capacity rubber material. The high-reinforced high-mechanical capacity rubber material comprises, by weight, 50 to 55 parts of butyl rubber, 25 to 32 parts of ethylene propylene diene monomer, 15 to 22 parts of polyacrylate rubber, 0.8 to 1.3 parts of tert-butyl cumyl peroxide, 0.5 to 1 part of 2-mercaptoimidazoline, 0.8 to 1.5 parts of silane coupling agent, 1 to 1.5 parts of N-Cyclohexyl-2-benzothiazolesulfenamide, 1 to 3 parts of nano-zinc oxide, 30 to 42 parts of montmorillonite, 30 to 40 parts of modified heavy calcium carbonate, 20 to 25 parts of ultrafine talcum powder, 15 to 22 parts of calcined clay, 1 to 2 parts of antioxidant 4020, 1 to 2 parts of antioxidant NBC, 1 to 2 parts of trioctyl trimellitate, and 0.5 to 1 part of dioctyl phthalate. The high-reinforced high-mechanical capacity rubber material is excellent in mechanical properties, excellent in reinforcing properties, and excellent in material compatibility.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber material with high reinforcement and high mechanical performance. 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 inc...

[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.
