Butyl reclaimed rubber and EPDM reclaimed rubber are all the ideal raw materials for producing rubber water-stop tapes. However, most of the water-stop tapes in the market are made of natural rubber products, but the high price of natural rubber and the large price fluctuations lead to natural rubber As the production cost of the water stop increases and it is difficult to control the cost within a reasonable range, many rubber product manufacturers that process the water stop with natural rubber have turned their attention to the latex produced from waste natural rubber and waste latex products Reclaimed rubber, then latex reclaimed rubber can produce water stop? What are the requirements, latex reclaimed rubber water stop can be used where?
In practical projects, the use of natural rubber production of water stop can usually long-term work in -35 ℃ ~ 60 ℃ environment, they are characterized by high content of plastic, good elasticity, elongation at break, the use of process In the force can produce high elastic deformation, effectively prevent the structural deformation joints at the seepage, leaking water, while in the process can also play a damping effect, the role of buffer to ensure that works can be carried out normally.
Latex reclaimed rubber is natural rubber, waste latex products as the main raw material to produce reclaimed rubber, feel good elasticity, high elongation at break, high quality latex reclaimed rubber products almost all indicators of the requirements of natural rubber, so from Performance latex reclaimed rubber to meet the demand for raw materials for water stop; from the price point of view, the price of latex reclaimed rubber is about 1/3 of the price of natural rubber, replaceable to natural rubber production of water stop can significantly reduce the production cost of water stop; Latex reclaimed rubber plasticity, anti-aging properties better than natural rubber, water-stop production process can save the cost of plastic-refining, and improve the anti-aging performance of the water stop, extend the service life; at the same time, latex reclaimed rubber and natural rubber It blends perfectly so it can not only replace natural rubber, but also combine with natural rubber to produce a higher standard of water stop tape.
In the actual construction process, water-stop response to a variety of working environment, so the production of water-stop material is not only latex reclaimed rubber, EPDM reclaimed rubber, butyl rubber reclaimed. In the event of oil medium should be used nitrile rubber reclaimed rubber production zone; case of weak acid, alkali corrosion medium, the temperature between -25 ℃ ~ 60 ℃, should use neoprene water stop. We will not discuss it here.
