Abstract

The invention discloses a Krah pipe. The Krah pipe comprises, by weight, 50-60% of HDPE resin, 10-15% of adhesive resin, 5-10% of CPE resin, 1-3% of a defoaming agent, 6-12% of PP resin, 0.8-2% of a lubricant, 1-3% of a stabilizer, 6-12% of ABS resin, 0.8-2% of a coupling agent, 1-3% of a plasticizer and 0.4-0.8% of a dispersing agent. The Krah pipe is excellent in bonding performance and high inrigidity, and the pressure resistance and the stripping performance are both improved.

Description

technical field [0001] The invention relates to a carat tube and a preparation method thereof, belonging to the technical field of carat tubes. Background technique [0002] The existing carat tube preparation method generally adopts PP small bellows as the inner lining, and wraps it in the HDPE rubber layer, and rolls it on the HDPE inner sheet. [0003] However, due to discontinuous production, the bonding effect of PP small bellows and HDPE is poor, and the plasticizing effect is also poor. Moreover, the compatibility between HDPE and PP is not good, which leads to low peel strength of HDPE, and it is difficult to improve the rigidity level of the carat ring. This further leads to the fact that after the carat pipe is buried in the ground, the product is prone to cracking under pressure, resulting in water leakage, which in turn affects the environment. At the same time, secondary rework is caused, which virtually causes a huge waste of project funds. Contents of the ...
