Abstract

The invention relates to a PVC-M high impact pipe, and in particular relates to a composite impact modifier and a PVC-M high impact pipe prepared by using the same. The composite impact modifier is prepared from the following raw materials: MBS resin, chlorinated polyethylene, an acrylate processing aid and a coupling agent. The composite impact modifier has good powder fluidity and also has good compatibility with PVC. The invention also provides the PVC-M high impact pipe prepared by using the composite impact modifier. The PVC-M high impact pipe is prepared from the following raw materials: PVC, the composite impact modifier, a stabilizer, stearic acid, PE wax, oxidized polyethylene wax, titanium pigment and activated calcium carbonate; and the PVC-M high impact pipe has excellent impact resistance.

Description

technical field [0001] The invention relates to a PVC-M high-impact pipe, in particular to a composite anti-impact modifier and the PVC-M high-impact pipe prepared by the same. Background technique [0002] Under the premise of basically not reducing the long-term strength of PVC-M, the toughness is 5 to 10 times higher than that of UPVC, and the notched impact strength is ≥30Mpa (20°C), which is more than 3 times that of UPVC. After the toughness is improved, the damage sensitivity is reduced, and the pipe is not easily injured or the degree of injury is greatly reduced, so that the impact on the long-term strength becomes smaller. Therefore, the design safety factor can be 1.6. Under the above-mentioned toughness, the coefficients verified by many countries, although the cost per ton of PVC-M is higher than that of UPVC, but due to the low value of the insurance coefficient and the thinner wall thickness, the price per meter is not higher than that of UPVC. In this way, ...
