PE pipe and production process thereof

Abstract

The invention discloses a PE pipe and a production process thereof. The PE pipe is prepared from the following components in corresponding parts by weight: 35-65 parts of PE resin, 10-20 parts of color master batch, 10-15 parts of toughening components, 0.1-0.2 part of antioxidant, 0.1-0.5 part of surface conditioning agent, 0.1-1 part of dispersing agent and 10-15 parts of flame retardant component, wherein the toughening components comprise a regenerated film material, toughening nylon and ceramic fine particles in weight ratio of (40-60%):(20-32%):(8-35%), and the regenerated film materialis a mixture prepared from recycled waste PE resin and toughening nylon by mixing, melting and cooling. By the arrangement, as a part of the toughening components, the regenerated film material effectively improves the toughness of pipes, and also is substituted for a toughening agent to greatly reduce the production cost; as collocated materials, the toughening nylon and the ceramic fine particles play an effective role of reinforcement, and also can enable the pipes to have good waterproof and heat-insulation effects; and the ceramic fine particles also provide good compressive strength, sothe pipes can adapt to higher lateral water pressure, and the application range of the pipes is expanded.

Description

technical field [0001] The invention relates to thermoplastic pipes, in particular to a PE pipe and its production process. Background technique [0002] PE pipe has excellent performance, can resist the corrosion of most living and chemical products, and has a certain degree of flexibility. It is one of the important choices of water supply pipes in municipal pipes. [0003] With the development of this year, the production and preparation process of PE pipes has been greatly improved. For example, the Chinese patent application publication number CN103881220A discloses a preparation method of anti-aging and antibacterial PE pipes. The nano-modified bamboo charcoal plastic particles are extruded through a twin-screw extruder after heating, and the finished product is obtained after cooling and vacuum setting. [0004] Although nano-modified bamboo charcoal plastic particles are used in the above scheme to replace the carbon black and inorganic metal antibacterial agents co...

Problems solved by technology

[0004] Although the above scheme uses nano-modified bamboo charcoal plastic particles to replace the carbon black and inorganic metal antibacterial agents commonly used in the prior art, the cost is reduced and the antibacterial effect is improved, but it is widely used in the water supply system of the municipal pipe network. PE pipes not only need to be improved in terms of antibacterial, but also need to pay attention to the different water pressures faced in different water supply systems, and PE pipes after long-term use are often prone to adverse phenomena such as pipe wall leakage, and also need to focus on Improve
