Industrial rubber sheets can be used as rubber pads, sealing gaskets or buffer rubber sheets in industrial and mining machinery or transportation. Among them, ordinary industrial rubber sheets will not be used in acid and alkali environments, high heat conditions, and oily media. raw material. However, natural rubber prices are high and prices fluctuate greatly. Rubber product manufacturers lack the ability to control the cost of natural rubber sheets, especially small and medium-sized enterprises. Therefore, ordinary industrial rubber sheet manufacturers hope to reduce the production cost of industrial ordinary rubber sheets through other raw materials.
1. Natural rubber + tire recycled rubber
When natural rubber is used as the main raw material to produce ordinary industrial rubber sheets, rubber product manufacturers can mix an appropriate amount of tire recycled rubber. The specific dosage is determined according to the performance requirements of the rubber sheet and the tire recycled rubber index. In general, the proportion of tire tread recycled rubber in natural rubber industrial rubber sheet is greater; the amount of tire recycled rubber in industrial rubber sheet with low rubber content is more. At present, when natural rubber and tire reclaimed rubber are used together to produce ordinary rubber sheets, the amount of tire reclaimed rubber varies from 30 to 200 parts.
2. Natural rubber + sole rubber
Sole reclaimed rubber products are low in price. They are often used in combination with natural rubber to produce low-grade ordinary industrial rubber sheets. Taking 100 parts of natural rubber as an example, the amount of reclaimed rubber used in rubber shoes can be increased to more than 150 parts, which significantly reduces raw material costs. It should be noted that when natural rubber and sole reclaimed rubber are used together to produce ordinary industrial rubber sheets, rubber product manufacturers need to appropriately reduce the amount of non-reinforced rubber fillers such as light calcium.
3. Natural rubber + general synthetic rubber + tire reclaimed rubber
In order to further improve the wear resistance and aging resistance of process rubber sheets, rubber product manufacturers usually mix a certain proportion of general synthetic rubber in industrial rubber sheets with natural rubber as the main raw material, with styrene-butadiene rubber and cis-butadiene rubber as the Lord. Ordinary industrial rubber sheets are produced by using natural rubber / styrene butadiene rubber / recycled rubber or natural rubber / butadiene rubber / recycled rubber in combination, which can significantly reduce the cost of raw materials and improve the comprehensive index and service life of industrial rubber sheets.
In actual production, rubber product manufacturers can also use natural rubber / styrene-butadiene rubber / butadiene rubber / recycled rubber in a certain proportion. Four rubbers can be used together to produce common industrial rubber sheets with higher cost performance.
4. Rubber + tire rubber powder
When reducing the production cost of natural rubber general industrial rubber sheets, rubber product manufacturers can mix the appropriate amount of tire rubber powder in the formula; compared with other rubber fillers 2LLYY0410, the effect of tire rubber powder in natural rubber is better. To a certain extent, improve the tear resistance and wear resistance of rubber compounds. Rubber product manufacturers can mix tire rubber powder in the formula of pure natural rubber industrial rubber sheets to reduce costs, or blend tire rubber powder in formulations containing other synthetic rubber or recycled rubber to further optimize industrial rubber sheet indicators and reduce more. Raw material cost.
In fact, there are not only several ways to reduce the production cost of natural rubber industrial rubber sheet. Rubber product manufacturers can also use tire recycled rubber, rubber shoe recycled rubber or tire rubber powder in the natural rubber sheet formula. The actual needs of the rubber sheet can be decided, and the editor will share with you the production formula of low-cost ordinary industrial rubber sheet and various precautions during the production process.
