Butyl reclaimed rubber produced from waste butyl inner tubes has excellent sealing, temperature resistance, corrosion resistance and vibration damping properties, and can replace butyl vulcanized rubber to manufacture various vulcanized rubber products, so as to control costs the destination. Butyl reclaimed rubber is widely used in vulcanized rubber products. Different types of hb butyl reclaimed rubber products must cooperate with each other in different management systems. There are two common cooperative management systems for reclaimed rubber in vulcanized rubber products.
The basic recipe of butyl reclaimed rubber: 100 parts of butyl reclaimed rubber, 6 parts of carbon black, 7 parts of vulcanized rubber oil, 50 parts of vulcanized rubber filler, 3 parts of beneficial agent, 1.5 parts of sulfur powder, and 3 parts of active zinc oxide.
Basic recipe 2 of butyl reclaimed rubber: 100 parts of butyl reclaimed rubber, 10 parts of carbon black, 8 parts of vulcanized rubber oil, 50 parts of vulcanized rubber filler, 3 parts of beneficial agent, 5 parts of urea-formaldehyde resin, and 6 parts of PA.
When butyl reclaimed rubber is used to produce vulcanized rubber products, the sulfur powder-thiuram vulcanization management system and its urea-formaldehyde resin vulcanization management system are commonly used at this stage. When butyl plastic pellets are vulcanized with sulfur powder, manufacturers of butyl reclaimed rubber products generally select sulfur powder/facilitator M/facilitator TMTD and use them, thiuram-type favorable agent TMTD and thiazole-type favorable agent M and Adjust the vulcanization level and high vulcanization efficiency of butyl reclaimed rubber as soon as possible; choose epoxy resin 2LLYY0316-SJ for butyl reclaimed rubber products when vulcanizing, and use thiazole-type favorable agent DM and thiuram-type favorable agent TMTD.
Different types of butyl reclaimed rubber products have different impact toughness and must cooperate with different reinforcement and filling management systems. At present, the common additives in the reinforcement and filling management system of butyl reclaimed rubber products are carbon black, calcium bicarbonate, ceramic mud, etc. When the butyl reclaimed rubber products require high impact toughness, why not choose super wear-resistant carbon black , medium and high wear-resistant carbon black or high wear-resistant carbon black; when the butyl reclaimed rubber stipulates that the plastic pellets have a good elongation at break, the semi-reinforced carbon black is more suitable; when the butyl reclaimed rubber is used to produce cheap vulcanized rubber products, it can be used in many applications Calcium bicarbonate, pottery clay, light calcium powder, etc. In order to improve the quality of butyl reclaimed rubber products, manufacturers of vulcanized rubber products can also select the modified material calcium bicarbonate when necessary.
The common vulcanized rubber oils in the softening management system of butyl reclaimed rubber products include aromatic oil, mechanical lubricating oil, etc. Among them, aromatic oil can not only improve the adhesion of reclaimed rubber, but also not easily significantly reduce the impact toughness of plastic particles. The butyl reclaimed rubber vulcanizate has good performance; however, attention must be paid to the harm of aromatic hydrocarbon oil to the heat generation of the butyl reclaimed rubber vulcanizate during the specific application process.
Effective design of the secret recipe for butyl reclaimed rubber products can not only control costs, but also improve the comprehensive index value and service life of butyl reclaimed rubber products.
