Synthetic plastic for manufacturing high temperature-resisting corrugated pipe

Abstract

The invention discloses synthetic plastic for manufacturing a high temperature-resisting corrugated pipe. The synthetic plastic is prepared from the following raw materials in parts by weight: 2500 to 2800 parts of polyvinyl chloride, 300 to 600 parts of polypropylene, 2 to 5 parts of zirconium tetrafluoride, 30 to 35 parts of polyether ether ketone, 130 to 140 parts of diisodecyl phthalate, 400 to 460 parts of polysorbate, 15 to 25 parts of molybdenum boride, 70 to 80 parts of methyl ethyl ketoxime, 8 to 16 parts of Butylmercaptooxo stannane, 200 to 230 parts of palm wax and 180 to 220 parts of dioctyl azelate. The synthetic plastic for manufacturing the high temperature-resisting corrugated pipe, disclosed by the invention, has better mechanical strength and better fatigue resistance, and cannot deform after being used under a higher environment temperature for a long time; the preparation technology of the synthetic plastic is relatively simple, the raw materials are relatively lowcheap, the manufacturing cost is low, the production speed is fast, higher economic value is obtained, and the application field of plastic corrugated pipes can be greatly broadened.

Description

technical field [0001] The invention relates to the field of corrugated pipe manufacturing, more precisely, a synthetic plastic used for manufacturing high temperature resistant corrugated pipes. Background technique [0002] There are two types of plastic bellows, one is completely airtight and watertight, such as used for propellant delivery of launch vehicles, gas, and water heaters; the other is continuously wound with strip materials, and ordinary coiled bellows are used Protective cables, such as magnetic card telephones, machine tools, and bellows of desk lamps are clamped with steel wires during the production process. [0003] Affected by the characteristics of plastics, plastic corrugated pipes have good elasticity, wear resistance and corrosion resistance at room temperature. At the same time, plastic corrugated pipes are easily deformed at higher ambient temperatures, and their mechanical properties are significantly reduced, or even completely melted. In this w...

Problems solved by technology

In this way, the plastic corrugated pipe cannot be applied to occasions with high temperature, which greatly limits the scope of use of the plastic corrugated pipe.
