Rubber water pipes are mainly used to transport inert gases such as water and air, and are generally processed from natural rubber as the main raw material. The pipe body is soft and the surface is smooth. In actual production, the price of natural rubber is high and the price fluctuates greatly. It is recommended to mix some low-priced rubber raw materials appropriately to reduce the cost of raw materials. So which rubber raw materials can be used in the production of natural rubber water pipes, the editor will share with you some low-cost rubber raw materials commonly used in the production of natural rubber water pipes.
1. Recycled rubber
Reclaimed rubber is a reprocessed rubber with certain plasticity and viscosity, which is processed by physical and chemical processes such as dispersion, heating, mechanical and chemical treatment of waste vulcanized rubber.
The price of reclaimed rubber is much lower than that of raw rubber, and it can replace all kinds of raw rubber to produce rubber products, effectively reducing the cost of raw materials. The latex reclaimed rubber 2ELYY91 in reclaimed rubber products is processed from waste natural rubber and waste natural rubber products. It can directly replace a certain proportion of natural rubber 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 have good compatibility with natural rubber, and can be used together with natural rubber to produce rubber water pipes, reducing more costs.
2. Vulcanized rubber powder
Compared with reclaimed rubber, the cross-linked rubber in waste rubber products is crushed by mechanical or freezing methods. The vulcanized rubber powder has a simpler production process and a very low price; filling it into natural rubber water pipes can not only effectively reduce the cost of raw materials, but also reduce the cost of raw materials. Reduce the deformation of semi-finished products, which is beneficial to exhaust. In actual production, natural rubber water pipes are reasonably mixed with vulcanized rubber powder, the tensile strength and elongation at break of rubber water pipes 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 soaring, styrene-butadiene rubber, butadiene rubber, etc. can be mixed in an appropriate amount 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 Wear resistance, heat resistance, aging resistance, etc. 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, anti-aging agent D 2 parts, 200 parts of precipitated calcium carbonate; total: 593.5 parts.
In actual production, the use of rubber water pipes with natural rubber as the main raw material is different, and different proportions of reclaimed rubber, vulcanized rubber powder and synthetic rubber can be mixed. Later, the editor will continue to discuss related issues with you.
