The traditional waterproof Electrical tape usually uses Neoprene or EPDM rubber as the main raw material. The preparation process of these materials has a certain impact on the environment, and the production process of Neoprene or Ethylene propylene rubber will produce pollutants. In recent years, with the continuous progress of science and technology, a more environmentally friendly waterproof Electrical tape has gradually entered the market, that is, the self adhesive EPDM waterproof Electrical tape is prepared from EPDM recycled rubber
EPDM reclaimed rubber is a recyclable rubber material made of EPDM die rubber or cutting material and other high content EPDM waste. Because of its good physical and mechanical properties and chemical resistance, it has been widely used in the preparation of waterproof Electrical tape
Preparation of self-adhesive EPDM waterproof Electrical tape with EPDM reclaimed rubber Formula:
Premium Hongyun EPDM recycled rubber 40kg, silica powder 8kg, talc powder 3kg, C5 resin 5kg, liquid paraffin oil 1.5kg, low molecular weight polyisobutylene 0.7kg
HY EPDM reclaimed rubber is the main raw material of this waterproof Electrical tape, accounting for about 80% of the formula. It is a polymer material with good weather resistance and chemical resistance, so it can ensure the service life of waterproof Electrical tape and the adaptability of the service environment; C5 coumarone and low molecular weight polyisobutylene are key components that increase the adhesive force of the tape, which can make the tape have good self-adhesive ability; Silica powder and talc powder are fillers used to adjust the viscosity and hardness of the adhesive tape; Paraffin oil is a plasticizer that can ensure that the surface of the tape does not dry up for a long time. After internal mixing, extrusion filtration, defoaming and other processes, the main materials for preparing self-adhesive EPDM waterproof Electrical tape can be obtained from EPDM reclaimed rubber
The process of preparing self-adhesive HYYR3-7-D4 EPDM waterproof Electrical tape with EPDM reclaimed rubber:
Add EPDM recycled rubber, fillers, plasticizers, and tackifiers in a certain proportion to the mixer and mix evenly. Heat the mixer at around 100 degrees Celsius for 5-8 minutes to prepare a rubber material with a certain viscosity and fluidity
Pour the evenly mixed rubber material into the extruder and filter through the sieve to remove any impurities or bubbles that may appear. The filtered rubber material enters the composite molding machine for fixed shape and printing. Cut the formed tape into strips of a certain length through a machine
Through the above process steps, EPDM recycled rubber with good waterproof, insulation and self-adhesive ability can be prepared to prepare self-adhesive EPDM waterproof Electrical tape
Preparation of self-adhesive EPDM waterproof Electrical tape with EPDM recycled rubber is a new material that can reduce cost on the premise of ensuring quality. Its preparation process is simple, cost is low, and service life is long. It has a wide range of applications
