Problems solved by technology

[0002] The pressure withstanding of the traditional high-pressure pipe must be proportional to its wall thickness, so the use can only start from the thickness of the material, which wastes the material and does not achieve the expected effect; otherwise, it will not be able to withstand high temperature and high pressure. In addition, traditional high-pressure pipes are commonly used in metal pipes.

Abstract

The invention relates to the field of chemical industry, and in particular relates to an external-pressure resistant carbon fiber high-pressure pipe. The external-pressure resistant carbon fiber high-pressure pipe comprises the following glue preparation raw materials in parts by weight: 1800-2000 parts of bisphenol A diglycidyl ether, 170-200 parts of trimethylolpropane glycidyl ether 6360, 1700 parts of methyl tetrahydrophthalic anhydride and 12-15 parts of 2,4,6-tris(dimethylaminomethyl)phenol. The external-pressure resistant carbon fiber high-pressure pip is prepared by the following steps of: fully and uniformly stirring the raw materials for later use; preparing the raw materials and placing the raw materials in a glue tank of a winding machine for later use; soaking carbon fibers in the glue tank, and preparing a product on the winding machine; and solidifying and heating the product, which concretely comprises the following steps of: raising the temperature to 60 DEG C from room temperature and keeping warm for 3 hours; raising the temperature to 100 DEG C and keeping warm for 3 hours; raising the temperature to 140 DEG C and keeping warm for 2 hours; raising the temperature to 160 DEG C and keeping warm for 4 hours; then naturally cooling the product until the difference between the product temperature and the external temperature is within the range of 10 DEG C, and taking out the product; and then standing the product for 200 hours at normal temperature.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a carbon fiber external pressure-resistant high-pressure pipe. Background technique [0002] The pressure withstanding of the traditional high-pressure pipe must be proportional to its wall thickness, so the use can only start from the thickness of the material, which wastes the material and does not achieve the expected effect; otherwise, it will not be able to withstand high temperature and high pressure. In addition, traditional high-pressure pipes are commonly used in metal pipes. Contents of the invention [0003] The purpose of the invention: to provide a carbon fiber external pressure-resistant high-pressure pipe with strong high-pressure resistance without increasing the thickness. [0004] In order to achieve the above object, the present invention takes the following technical solutions: [0005] The carbon fiber external pressure-resistant high-pressure pipe is cha...
