Silica gel inner lining teflon flexible pipe and manufacturing technology thereof

Abstract

The invention discloses a silica gel inner lining teflon flexible pipe which comprises a teflon casing pipe; the outer side wall of the teflon casing pipe is coated with a coupling agent layer; a silica gel layer is fixed to the outer side wall of the coupling agent layer; a PET outer pipe is fixed to the outer side wall of the silica gel layer; a first silica gel cloth layer, a stainless steel wire layer and a second silica gel cloth layer are composited in the PET outer pipe; the first silica gel cloth layer of the PET outer pipe is wound on the outer side wall of the silica gel layer; the stainless steel wire layer is wound on the outer side wall of the first silica gel cloth layer; and the second silica gel cloth layer is wound on the outer side wall of the stainless steel wire layer. A manufacturing technology of the silica gel inner lining teflon flexible pipe comprises the following steps that the teflon casing pipe sleeves a mandrel, so as to realize fixing; and the outer surface of the teflon casing pipe is coated with a coupling agent. Through the first silica gel cloth layer, the second silica gel cloth layer and the stainless steel wire layer, the toughness and the strength of a pipe body are improved, so that the silica gel inner lining teflon flexible pipe is not prone to bending or fracture, and the silica gel inner lining teflon flexible pipe has the characteristics of high-temperature resistance, corrosion resistance and acid-base resistance and is significant in effect.

Description

Technical field: [0001] The invention relates to the technical field of plastic pipe bodies, and more specifically relates to a silicone-lined Teflon hose and a manufacturing process thereof. Background technique: [0002] At present, the Teflon-lined hoses on the market are relatively thick. Once they are bent or hit, they are easy to be damaged, cracked, and affect the use. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a food-grade hose with inner fluorine and outer silicon, which improves the toughness and strength of the pipe body through the first adhesive plaster layer, the second adhesive layer and the stainless steel wire layer, It is not easy to bend and break, and has high temperature resistance, corrosion resistance, acid and alkali resistance, and the effect is remarkable. [0004] The scheme that the present invention solves described technical problem is: [0005] A silicone-lin...
