The appearance of reclaimed rubber solves the problem that most waste rubber resources pollute the environment. In particular, waste tires and tire reclaimed rubber are typical of "black" to "green". The reclaimed rubber has a wide source of raw materials (a large amount of used tires are produced and regenerated each year. Plastic is the main way of recycling waste tires), low prices, good performance, is used in all walks of life, including tire reclaimed rubber in the construction of the waterproofing membrane is one of its major uses, as the construction of the first A waterproof barrier, of great significance. Tire reclaimed rubber with a small amount of natural rubber used in conjunction with waterproofing membrane, both to ensure product quality, but also can significantly reduce the cost of raw materials.
Xiaobian and here to share with you a reclaimed rubber and a small amount of natural rubber waterproofing membrane production formula:
Tire recycled rubber, 200 parts; Natural rubber, 10 parts; Powdered powder, amount; Calcium carbonate (light calcium), 50 parts; Talc, 10 parts; Carbon black N330, 10 parts; , 2.5 parts; antioxidant RD, 1 part; antioxidant 4010NA, 0.65 parts; paraffin, 3 parts; accelerator DM, 1.2 parts; SA, 3 parts;
Adding a small amount of natural rubber in the formula of tire reclaimed rubber waterproof roll can improve the amount of glue in the formula, improve the poor tear resistance of tire reclaimed rubber products, and the defect of poor flex cracking, and improve the elasticity of tire reclaimed rubber waterproofing membrane With the tear strength, to extend the service life; the above formula also added a certain amount of rubber powder, calcium carbonate and carbon black, which can reduce raw material costs, but also can improve the performance of waterproofing membrane, improve the abrasion resistance of waterproofing membrane; The agent RD effectively inhibits the thermal oxygen aging, and the dispersion of the anti-aging agent 4010NA in the rubber compound does not affect the vulcanization efficiency of the reclaimed rubber waterproof material. Adding a certain amount of calcium carbonate to the waterproof material material can improve the reinforcement of the tire regenerated rubber. Sex and maneuverability, improve the abrasion resistance, tear resistance and tensile strength of waterproofing membrane products, and further improve the overall performance of waterproofing membranes.
When using tire reclaimed rubber to produce waterproofing membranes, try to select high-quality tire reclaimed rubber products under the conditions of cost permitting; in the production process, we must strictly follow the formulated formulas to carry out related process operations to avoid mispronunciation and many Weigh and weigh the occurrence of the situation, and grasp the timing of the addition of each compounding agent, and strictly control the quality of the reclaimed rubber waterproofing membrane in all aspects.
