Rubber water pipes are mainly used to transport inert gases such as water and air, and are generally processed with natural rubber as the main raw material, with a soft pipe body and a smooth surface. In actual production, the price of natural rubber is high and the price fluctuates greatly, so it is recommended to appropriately mix some low-cost rubber raw materials to reduce the cost of raw materials. So which rubber raw materials can be used in the production of natural rubber water pipes, Xiaobian will share with you some low-cost rubber raw materials commonly used in the production of natural rubber water pipes today.
1. Recycled rubber
Reclaimed rubber is a kind of rubber with certain plasticity and viscosity that can be reprocessed by dispersion, heating, mechanical and chemical treatment and other physical and chemical processes of waste vulcanized rubber.
The price of reclaimed rubber is much lower than that of raw rubber, which can replace all kinds of original rubber to produce rubber products, effectively reducing the cost of raw materials. The latex reclaimed rubber in the reclaimed rubber products is processed from waste natural rubber and waste natural rubber products, which can directly replace a certain proportion of natural rubber 2ELYY91WFM to produce rubber water pipes, effectively reducing the cost of raw materials; The main components of tire reclaimed rubber are natural rubber, synthetic rubber and carbon black, which have good compatibility with natural rubber, and can be used in combination with natural rubber to produce rubber water pipes to reduce more costs.
2. Vulcanized rubber powder
Compared with reclaimed rubber, the vulcanized rubber powder obtained by crushing the cross-linked rubber in waste rubber products by mechanical or freezing methods is more simple and the price is very low; Filling into natural rubber water pipes can not only effectively reduce the cost of raw materials, but also reduce the deformation of semi-finished products, which is conducive to exhaust. The natural rubber water pipe is reasonably mixed with vulcanized rubber powder, the tensile strength and elongation at break of the rubber water pipe are basically unchanged, and the fatigue resistance and crack growth resistance of vulcanized rubber are significantly improved.
3. Synthetic rubber
When the price of natural rubber is rising, styrene-butadiene rubber and butadiene rubber can be appropriately mixed in the production of rubber water pipes with natural rubber as the main raw material, which can not only maintain the production cost in a relatively stable state, but also further improve the wear resistance, heat resistance and aging resistance of rubber water pipes.
4. Natural rubber + tire reclaimed rubber + vulcanized rubber powder to produce rubber water pipe reference formula
100 parts of natural rubber, 160 parts of tire reclaimed rubber, 100 parts of vulcanized rubber powder, 6 parts of sulfur, 1.5 parts of accelerator DM, 10 parts of zinc oxide, 2 parts of stearic acid, 2 parts of paraffin, 10 parts of mineral rubber, 2 parts of antioxidant D, 200 parts of precipitated calcium carbonate; Total: 593.5 copies.
In the actual production, the rubber water pipe with natural rubber as the main raw material can be used in different occasions, and can be mixed with different proportions of reclaimed rubber, vulcanized rubber powder and synthetic rubber.
