The largest use of butyl rubber reclaim rubber is the production of highly air-tight rubber products, such as automobile and motorcycle inner tube, it is based on waste butyl inner tube as the main raw material of renewable rubber products, retaining the butyl rubber good air tightness, The use of butyl rubber instead of butyl rubber in the butyl inner tube formula can reduce the cost of raw materials. Most inner tube manufacturers use butyl rubber and butyl base rubber to produce butyl inner tube, which can reduce the cost of raw material of butyl inner tube , But also to improve the rubber processing performance and improve the quality of butyl inner tube products, Xiao Bian and share with you a butyl rubber reclaimed rubber and butyl rubber used in conjunction with the production of butyl inner tube formula:
Butyl rubber, 80 parts; EPDM rubber, 20 parts; butyl reclaimed rubber, 100 parts; stearic acid, 1 part; nano zinc oxide, 5 parts; carbon black N660, 50 parts; carbon black N550, 25 ; Paraffin oil, 22 parts; accelerator M, 0.5 parts; accelerator EZ, 0.5 parts; accelerator TMTD, 1 part; sulfur, 2 parts;
The reclaimed rubber with a higher proportion of the reclaimed rubber in the formula accounts for 50% of the total amount of the rubber compound and can be used for producing the medium-grade butyl inner tube to significantly reduce the raw material cost; if the low-grade small butyl inner tube is produced, the physical and mechanical properties The requirements are not high, you can completely use the production of butyl rubber reclaimed, butyl reclaimed rubber specific indicators according to the choice of butyl tube products; If the use of butyl reclaimed rubber production of high-grade butyl tube, the data show that high-quality butyl rubber regeneration With about 15% to meet the performance requirements of high-index butyl inner tube; Therefore, the amount of butyl rubber reclaimed in the use of butyl inner tube is not static, usually based on butyl inner tube index and butyl rubber quality to determine.
In addition to high quality butyl reclaimed rubber, a reasonable formula design is the basis to ensure the quality of butyl inner tube products. For example, the reclaimed rubber with butyl rubber and butyl rubber can improve the aging of butyl rubber tube. Soft sticky problem, prolong the service life of the product; butyl reclaimed rubber tube formula dosage of curing agent, reinforcing agent dosage, filler dosage needs reasonable design.
