Waterproof membrane is a flexible building material product that can be bent into a roll. Its main function is to resist external rainwater and groundwater penetration. It is widely used in building walls, roofs, tunnels, highways and other occasions. In actual production, natural rubber, styrene butadiene rubber, ethylene-propylene rubber, and butyl rubber can all be used as the main raw materials for waterproofing membranes. The main components of reclaimed tire rubber are natural rubber, styrene-butadiene rubber and carbon black, etc., which can be used alone or with a small amount of natural rubber and styrene-butadiene rubber to produce waterproof membranes, effectively reducing costs.
1. The reference formula for the production of waterproof membranes with fully reclaimed rubber
100 parts of reclaimed tire rubber, 1.2 parts of zinc oxide, 0.2 parts of stearic acid, 0.2 parts of antioxidant D, 25 parts of clay, 3.7 parts of engine oil, 0.5 parts of accelerator DM, 1.2 parts of sulfur; total: 132 parts.
2. Reclaimed rubber/styrene butadiene rubber production waterproof membrane formula
150 parts of tire reclaimed rubber, 25 parts of styrene butadiene rubber, 1 part of antioxidant D, 1 part of paraffin, 1 part of stearic acid, 35 parts of carbon black N330, 4 parts of engine oil, 0.3 parts of accelerator D, 0.9 parts of accelerator DM, Sulfur 2.8 parts; Total: 221 parts.
3. Reclaimed rubber/natural rubber production waterproof membrane formula
200 parts of reclaimed tire rubber, 10 parts of natural rubber, 5 parts of zinc oxide, 2 parts of stearic acid, 1 part of antioxidant RD, 0.6 part of antioxidant 4010NA, 3 parts of paraffin wax, 50 parts of light calcium, 10 parts of talcum powder, carbon black 10 parts of N330, 7 parts of engine oil, 1.2 parts of accelerator DM, 2.2 parts of sulfur; total: 302 parts.
4. Application skills of tire reclaimed rubber in waterproof membrane
Tire reclaimed rubber has many sources of raw materials and low product prices. It can be used in the production of various rubber products, effectively reducing the cost of raw materials. When using reclaimed tire rubber to produce cost-effective waterproof membranes, tire tread reclaimed rubber 2YLYY1116, fine tire reclaimed rubber, etc. are generally used. The finished waterproof membrane has better performance and longer life. In actual production, proper adjustment of the tire reclaimed rubber waterproof membrane formula can further optimize the performance and life of the finished product while reducing costs.
