Abstract
The invention relates to a high-temperature resistance plastic corrugated pipe which comprises a pipe body, an inner coating and an outer coating. The pipe body is made of PP plastics, the outer coating is made of PA plastics, and the inner coating is made of polyimide films. According to the high-temperature resistance plastic corrugated pipe, the three-layer composite structure is adopted, the temperature distortion degree of the corrugated pipe under the high temperature condition is reduced by wrapping high-temperature resistance materials on the inner coating and the outer coating, and the using temperature upper limit of the pipe is improved. The high-temperature resistance plastic corrugated pipe is simple in structure, low in cost and suitable for industrial production.
Description
Technical field
The present invention relates to a kind of bellows, be specifically related to a kind of high-temperature resistance plastice bellows.
Background technique
The bellows of current use, especially plastic film capicitor are generally not good enough for the tolerance performance of high temperature, just may start to melt bad, distortion under 70 DEG C ~ 150 DEG C environment.And the bellows price adopting other exotic materials such as metal to make is higher, complex structure, be not suitable for promoting.
Summary of the invention
Goal of the invention: the object of the invention is, in order to overcome prior art Problems existing, to provide a kind of high-temperature resistance plastice bellows.
Technological scheme: a kind of high-temperature resistance plastice bellows of the present invention comprises body, undercoating and external coating, and described body is made up of PP plastics, and described external coating is made up of PA plastics, and described undercoating is Kapton.
Preferably, the PP plastics of described body are the polypropylene copolymer containing 5% ~ 8% ethene.
Preferably, described internally coated thickness is 0.1mm ~ 0.5mm.
Beneficial effect: a kind of high-temperature resistance plastice bellows of the present invention adopts three-layer composite structure, is decreased the temperature distortion degree of bellows under the condition of high temperature, improves the upper limit of pipe fitting serviceability temperature by the exotic material of inside and outside coating coated.Structure of the present invention is simple, and cost is lower, is suitable for industrial production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
