In general, the inner rubber of the cloth sandwiched air and water hose is required to have good compactness, elasticity, softness and aging resistance. It is generally processed with natural rubber, styrene butadiene rubber and cis polybutadiene rubber as the main raw materials; The production cost of air hose can be effectively reduced by mixing appropriate amount of recycled tire rubber. How much recycled tire rubber should be added to the inner layer of the cloth clamping water hose? How to design the inner layer rubber formula of the cloth sandwiched air hose containing recycled tire rubber?
1. Mix 80 parts of recycled tire rubber to produce the reference formula of the inner layer rubber of the air hose with cloth
20 portions of natural rubber, 80 portions of styrene butadiene rubber, 80 portions of recycled tire rubber, 5 portions of zinc oxide, 2.5 portions of stearic acid, 2 portions of antioxidant D, 55 portions of carbon black N660, 34 portions of light calcium, 90 portions of clay, 5 portions of coumarone resin, 1.5 portions of rosin, 8 portions of asphalt, 12 portions of tall oil, 1.7 portions of accelerator CZ, 0.45 portions of accelerator TMTD, 2.85 portions of sulfur; Total: 400 copies.
2. Mix 100 parts of recycled tire rubber to produce the reference formula for the inner layer of the cloth sandwiched air hose
100 natural rubber, 100 recycled tire rubber, 5 zinc oxide, 3.5 stearic acid, 1.5 antioxidant A, 1.5 antioxidant D, 60 spray carbon black, 105 light calcium, 18 heavy oil, 1.6 paraffin, 1 accelerator M, 2.9 sulfur; Total: 400 copies.
3. Mix 120 parts of recycled tire rubber to produce the reference formula of the inner layer rubber of the air hose with cloth
20 natural rubber, 80 styrene butadiene rubber, 120 recycled tire rubber, 5 zinc oxide, 2.5 stearic acid, 1.5 antioxidant A, 1.5 antioxidant D, 1.2 paraffin wax, 50 carbon black N660, 60 light calcium, 50 clay, 2 engine oil, 1.3 accelerator DM, 1.8 accelerator CZ, 3.2 sulfur; Total: 400 copies.
When using recycled tire rubber to reduce the production cost of the inner layer of feng shui hose, it is recommended to use fine recycled tire rubber, superfine recycled tire rubber, and recycled tire tread rubber. The sulfur accelerator system is often used when the outer layer of the cloth clamping feng shui hose is mixed with the reclaimed tire rubber 2SLY16; With the increase of the amount of reclaimed rubber, the amount of sulfur and accelerator can be appropriately increased; At the same time, appropriately adjust the dosage of reinforcing agent, filler and softener.
In actual production, the recycled tire rubber can also be used in the production of the outer rubber of the cloth clamping water hose and the rubber wiping of canvas. Later, Xiaobian will continue to discuss relevant issues with you.
