The function of the rubber cushion belt is to protect the inner tube contact surface from the wear of the rim. It is placed between the inner tube and the rim, which directly affects the service life of the automobile tire. In actual production, the rubber cushion belt can be completely natural rubber, or combined with butadiene rubber, styrene butadiene rubber, and tire reclaimed rubber can be used to significantly reduce the cost of raw materials. Reasonable use of reclaimed tire rubber in the production process of rubber products can achieve the dual purpose of reducing costs and ensuring quality. So what issues should be paid attention to when using reclaimed tire rubber to reduce the cost of rubber pads?
1. Application method of tire reclaimed rubber in rubber cushion belt
The reclaimed tire rubber made from waste tires has good compatibility with natural rubber, styrene butadiene rubber, butadiene rubber and other general rubbers, and can be directly blended into the rubber cushion belt production formula. At present, tire reclaimed rubber can be used with natural rubber to produce rubber cushion belts, or you can choose tire reclaimed rubber/natural rubber/butadiene rubber to produce rubber cushion belts, or use tire reclaimed rubber 2LLYY720 together with natural rubber/styrene butadiene rubber, or even You can choose to use tire reclaimed rubber/natural rubber/butadiene rubber/styrene butadiene rubber; based on the actual needs of the rubber cushion belt, choose a production method that is more suitable for cost and performance.
2. How to choose tire reclaimed rubber for rubber pad belt
Tire reclaimed rubber can be divided into tread reclaimed rubber, full tire reclaimed rubber, sidewall reclaimed rubber, etc. according to the waste tire position. According to the fineness, it can be divided into ordinary reclaimed rubber (30-40 mesh), fine reclaimed rubber (60 mesh) and Superfine tire reclaimed rubber (80 mesh or higher). When using tire reclaimed rubber to reduce the production cost of rubber cushion belts, in order to ensure the mechanical strength of the cushion rubber, rubber product manufacturers can choose tread reclaimed rubber with higher effective rubber hydrocarbon content, and the finished cushion belt has higher mechanical strength and better wear resistance. , Longer service life; choose 60 mesh or higher fineness reclaimed rubber to ensure the smooth and bright surface of the rubber cushion belt, and avoid bubbles or impurities in the finished cushion belt.
3. Reasonably control the amount of reclaimed tire rubber in the rubber cushion belt
Product quality is the foundation of an enterprise. In actual production, only by selecting the appropriate tire reclaimed rubber and reasonably controlling the amount of tire reclaimed rubber in the cushion belt formula can the product quality be guaranteed. Under normal circumstances, when tire reclaimed rubber and natural rubber are used together to produce rubber cushions, the amount of tire reclaimed rubber in 100 parts of natural rubber should be controlled between 200-250 parts; tire reclaimed rubber is combined with natural rubber/styrene butadiene rubber. When used, the addition amount of tire reclaimed rubber in 100 parts of raw rubber should not exceed 150 parts; when tire reclaimed rubber is used together with natural rubber/butadiene rubber, the addition amount of tire reclaimed rubber in 100 parts of raw rubber should be controlled at 150-180 parts.
When using reclaimed tire rubber to reduce the production cost of rubber cushion belt rubber, rubber products manufacturers need to choose a suitable application method, select the tire reclaimed rubber according to actual needs, and reasonably control the amount of reclaimed rubber to lay a good foundation for rubber cushion belt production. In addition, when tire reclaimed rubber reduces the production cost of rubber cushion belts, it is necessary to appropriately adjust the rubber product formula to further optimize the quality of the finished cushion belt while reducing costs, so as to reduce more production costs while ensuring quality.
