Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an environmentally friendly, heat-resistant, flame-resistant, aging-resistant and modified natural rubber material. Background technique [0002] At present, rubber materials and their products are developing vigorously. They are rapidly replacing natural polymers such as steel, metal, cement, wood, and cotton, and are widely used in various sectors of the national economy such as industry, agriculture, and military affairs. Natural rubber materials are used in long-term storage and use. In the process, it is affected by heat energy, mechanical energy, light energy and radiation energy, plus the chemical reaction of oxygen, ozone, moisture and variable price metals and metal ions, the rubber sheath material gradually becomes soft and sticky, hard and brittle or turtle The aging phenomenon of cracking will make its mechanical properties deteriorate or even lose its origin...

[0002] At present, rubber materials and their products are developing vigorously. They are rapidly replacing natural polymers such as steel, metal, cement, wood, and cotton, and are widely used in various sectors of the national economy such as industry, agriculture, and military affairs. Natural rubber materials are used in long-term storage and use. In the process, it is affected by heat energy, mechanical energy, light energy and radiation energy, plus the chemical reaction of oxygen, ozone, moisture and variable price metals and metal ions, the rubber sheath material gradually becomes soft and sticky, hard and brittle or turtle The aging phenomenon of cracking will make its mechanical properties deteriorate or even lose its original properties, resulting in failure during use, and synthetic materials need to be added during the preparation process, and synthetic materials often contain high halogens, which can be burned during combustion. A large amount of toxic gas is produced, causing harm to the environment and posing a huge threat to people's life safety. How to modify natural rubber to prepare an environmentally friendly, aging-resistant, heat-resistant and flame-resistant rubber material has become a current problem. technical issues
