Problems solved by technology

The airtightness of the tire is also an important indicator for judging the tire. If the airtightness of the tire is good, the air pressure in the tire can be kept stable for a long time, thereby ensuring the performance of the tire. On the contrary, if the airtightness of the tire is not good, the tire often It is easy to be damaged when driving under the lack of air state, and it is dangerous if it is driven at high speed
[0003] The current tire reinforcement materials are added to improve the airtightness of tires, but they are often insufficient in rigidity, weak in tensile strength, elasticity and electrical properties, weak in ultimate deformation capacity, poor in flexion and resilience, and easily cause material layers to shift. , bulging phenomenon, affecting high-speed performance
The material has weak cohesion, poor aging resistance, insufficient cohesion, and poor heat resistance, which can easily cause cracks in the material layer, material sagging when moving at high speed, and poor weather resistance of the material, etc.

Abstract

The invention provides a polymer mixed material capable of enhancing the airtightness of a tire, and relates to the field of tire materials. The polymer mixed material comprises following components in percentage by weight: 58 to 60% of styrene high molecular compounds, 25 to 35% of a tackifier, 5 to 6% of a softener, 3 to 4% of an anti-aging agent, and 2% of nano powder. The provided polymer mixed material can effectively improve the rigidness, tensile strength, elasticity and electrical property of a material, and has little permanent deformation, a good bending performance, and excellent resilience. Furthermore, the mixed material can enhance the adhesive property of a material, strengthens the bonding force between a material and the surface a contacted object, and has an anti-aging performance. The cohesion force is greater than the destructive force generated by external factors or high speed movement, thus cracking or sagging is prevented, the weatherability is improved, the airtightness of a tire is greatly improved, and tire burst caused by tire leakage due to insufficient airtightness of a tire is prevented.

Description

technical field [0001] The invention relates to the field of tire materials, in particular to a polymer mixing material capable of enhancing tire airtightness. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. The airtightness of the tire is also an important indicator for judging the tire. If the airt...
