Organosilane crosslinked polyethylene composite tube

Abstract

The invention discloses an organosilane crosslinked polyethylene composite tube. The organosilane crosslinked polyethylene composite tube comprises a tube body and an organosilane crosslinked polyethylene inner layer and is characterized in that at least one penetrating hole is distributed in the tube body in the axial direction at equal distances; the organosilane crosslinked polyethylene inner layer is arranged on the inner wall of the tube body; a thermoplastic plastic structural layer is extruded on the outer wall of the organosilane crosslinked polyethylene inner layer in a composite manner; a foam heat preservation layer is arranged on the outer wall of the thermoplastic plastic structural layer in a composite manner; and a double-wall portion used for segmenting is arranged between adjacent penetrating holes. According to the tube, in use process, the heat preservation capability, the inflaming retarding capability, the heat insulation capability and the anti-freezing capability of the tube can be effectively improved, and external tension generated by water pressure in the tube body can be effectively offset, so that tension stress of the tube body can be greatly improved.

Description

technical field [0001] The invention relates to a silane cross-linked polyethylene composite pipe. Background technique [0002] When the existing pipes are used in the northern alpine regions, they are prone to problems such as poor antifreeze effect, and because the external tension that the pipe body can bear is limited, it will lead to cracking and cannot be used in places with high water pressure, resulting in Difficulties in implementing durability. Contents of the invention [0003] In order to solve the above-mentioned existing shortcomings, the main purpose of the present invention is to provide a practical silane cross-linked polyethylene composite pipe, which can effectively improve the heat preservation, flame retardancy, heat insulation and antifreeze capabilities of the pipe during use, and can effectively eliminate Resists the external tension generated by the water pressure in the pipe body, greatly increasing the tension resistance of the pipe body.
