EPDM renewable plastic high temperature, anti-aging, ozone resistance, corrosion resistance, is the largest amount of waterproofing membrane material. The use of EPDM reclaimed rubber and EPDM and the production of waterproofing membrane, not only can improve the waterproofing membrane product performance, but also greatly reduce the cost of raw materials. Xiaobian today to share with you two EPDM waterproofing membrane waterproofing recipes added.
1, EPDM reclaimed rubber: 100 parts; EPDM gum: 74 parts; carbon black: 45 parts; paraffin oil: 35 parts; light calcium carbonate: 65 parts; accelerator M: 1.5 parts; Agent BZ: 1 part; Accelerator ZDC: 1 part; Accelerator TMTD: 1 part; Stearic acid: 1 part; Zinc oxide: 3 parts; Sulfur: 1.2 parts; Total: 328.7 parts;
2, EPDM reclaimed rubber: 100 parts; EPDM gum: 74 parts; carbon black: 45 parts; paraffin oil: 35 parts; tall oil: 5; light calcium carbonate: 65 parts; 1 part of accelerator ZTD: 1 part of accelerator ZTD: 1 part of accelerator TMTD: 1 part of stearic acid; 1 part of stearic acid; 3 parts of zinc oxide; 1.2 parts of sulfur; 333.7 parts in total; Time: 10min.
The two waterproofing membrane EPDM reclaimed rubber and plastic ratio is the same, but added five tall oil, the amount of other additives unchanged, so the curing time used in the formula is different. The main components of tall oil fatty acids and rosin acid, compared with the commonly used rubber oil emulsification speed, excellent dispersion, do not migrate to improve the overall performance of waterproofing membrane can also slow down the curing rate. Here, Xiao Bian recommended the use of a second formula to produce waterproofing membrane, because curing a long time, produced waterproofing membrane product performance better.
