Construction rubber ash bucket is a commonly used tool in construction sites, mainly used to transport various mortar, concrete, cement and other building materials, generally processed from natural rubber and styrene-butadiene rubber as raw materials, and has good wear resistance at room temperature and low temperature; Carbon black reinforcement is used to further improve the wear resistance and impact resistance of the ash barrel. The production of rubber ash barrels for construction with reclaimed rubber and reclaimed rubber powder as the main raw materials can not only ensure the performance of the product, but also effectively reduce the production cost.
1. Vulcanization formula for the production of rubber ash barrels for construction with reclaimed rubber/reclaimed rubber powder
(1) 70 parts of reclaimed rubber, 30 parts of reclaimed rubber powder, 1 part of zinc oxide, 2 parts of paraffin, 0.2 parts of accelerator D, 0.5 parts of accelerator M, 1.3 parts of sulfur; 105 in total.
(2) 60 parts of reclaimed rubber, 40 parts of reclaimed rubber powder, 1 part of zinc oxide, 2 parts of paraffin, 0.2 parts of accelerator D, 0.3 parts of accelerator M, 0.1 parts of accelerator TMTD, 1.4 parts of sulfur; 105 in total.
2. Formula design of rubber ash barrel for the production of reclaimed rubber/reclaimed rubber powder for construction
The design of rubber ash drum formulations for construction needs to take into account factors such as abrasion resistance, impact resistance, low temperature resistance and cost-effectiveness. Reclaimed rubber has the basic performance characteristics of rubber, low price, good elasticity, wear resistance, aging resistance, and the appropriate amount of rubber powder combined to produce rubber ash bucket can meet the performance requirements of ash bucket, suitable for frequent use on construction sites and complex environmental conditions of the scene.
The sulfur vulcanization system is mostly used in the production of reclaimed rubber/reclaimed rubber powder in construction ash barrels, and the accelerator D/M or accelerator TMTD is used with sulfur to improve the vulcanization efficiency and the wear resistance of the finished product. Zinc oxide E4LYY81 as an active agent and reinforcing agent, which can increase the rate of vulcanization, enhance corrosion resistance, tear resistance and wear resistance; Paraffin wax can improve the aging resistance and flexibility of rubber, and at the same time form a wax film on the surface of the ash barrel, preventing cement or lime mortar from sticking and facilitating demoulding.
As a new raw material to replace high-priced raw rubber, reclaimed rubber can be used in the production of rubber ash barrels in the construction industry, which can reduce the cost of raw rubber; Reclaimed rubber powder can improve the tensile strength and wear resistance of rubber to a certain extent. Reasonable design of reclaimed rubber/reclaimed rubber powder ash barrel formula, the finished product is lighter than the iron drum, and should not be deformed and rusted; Compared with plastic barrels, it is durable, low temperature resistant, impact resistant and other properties.
