Abstract

The invention discloses a high-toughness polyethylene plastic pipe fitting and a preparation method thereof, and relates to the technical field of pipeline materials. The high-toughness polyethylene plastic pipe fitting comprises a pipe body, protruding parts are fixedly connected to the peripheral side of the pipe body, a plurality of protruding parts and through holes are arranged at equal angles, the protruding parts are arc-shaped protrusions, and a silk screen is arranged in the pipe body. The chlorinated polyethylene, the polypropylene and the toughening master batch are used as main materials, and the chlorinated polyethylene is a thermoplastic synthetic material with excellent performance and has the characteristics of small specific gravity, no toxicity and easiness in processing, so that the toughness strength and the impact resistance of the pipeline are improved; according to the present invention, through reasonable using of the excellent synergistic effect of the formula raw material components, the prepared material can meet the requirements of the compressive strength, the tensile strength, the impact resistance and other performances so as to meet the related performance requirements, and further improves the tensile strength, the temperature resistance, the wear resistance, the aging resistance and the like to different degrees, such that the requirements of the whole market are met, and the sales market can be further opened.

Description

technical field [0001] The invention relates to the technical field of pipeline materials, in particular to a high-toughness polyethylene plastic pipe fitting and a preparation method thereof. Background technique [0002] Polyethylene pipe is one of the most common pipes. It has the advantages of acid resistance, alkali resistance, oil resistance, corrosion resistance, light weight, low cost and long service life. It is used in water supply, drainage, heating, gas supply, agricultural irrigation, water conservancy It is widely used in engineering and various industrial devices. The modified polyethylene pipe system started late, but developed rapidly. Compared with traditional ductile iron pipes and steel pipes, PE pipes are hygienic, corrosion-resistant, and convenient and quick to lay. The flexible and weldable properties of PE pipes naturally become the first choice for non-excavation pipes. In order to adapt to non-excavation laying, they can be directly laid in the or...
