Reinforced and toughened PP single-wall corrugated pipe and preparation method thereof

Abstract

The invention provides a reinforced and toughened PP single-wall corrugated pipe. The reinforced and toughened PP single-wall corrugated pipe is prepared from the following raw materials in percentage by mass: 70% of PP a polypropylene raw material, 5% of a PP polypropylene reclaimed material, 8%-10% of reinforcing functional talcum powder, 2%-4% of carbon black, 0.5%-0.6% of a defoamer, 2%-4% of a silane coupling agent, 0.2%-0.3% of a maleic anhydride grafted polymer, 1.3%-1.4% of an antioxidant, and 5%-8% of an ethylene / vinyl acetate copolymer. The preparation method comprises the steps of proportionally mixing the raw materials and preparing the reinforced and toughened PP single-wall corrugated pipe by use of an extruder or a forming machine. The reinforced and toughened PP single-wall corrugated pipe has the advantages that the rigidity and the flexibility of the PP single-wall corrugated pipe are improved, rigid and flexible complementation is realized, and the elongation at break is increased to 350% or more, and consequently, the usability of the product is improved and the cost is reduced.

Description

technical field [0001] The invention relates to a PP single-wall corrugated pipe, in particular to a reinforced and toughened PP single-wall corrugated pipe and a preparation method thereof. Background technique [0002] Corrugated pipes made of plastic and other materials play an irreplaceable role in the fields of medium transmission, power threading, machine tools, household appliances, etc. Single-wall corrugated pipes are widely used. The existing single-walled 26MPa-28 MPa, its bearing strength is limited and its toughness is low, which cannot meet the application requirements. And its production process is complicated, and production cost is high. Therefore, it is urgent to provide an alternative upgrade product with high strength and high toughness. Contents of the invention [0003] The object of the present invention is to provide a reinforced and toughened PP single-wall corrugated pipe and its preparation method, so as to solve the problems existing in the ba...
