Embodiment Construction

[0019] Such as figure 1 , 2 As shown, the HDPE and PVC plastic-plastic composite winding pipe in this embodiment has a winding pipe body 1, and the pipe wall of the winding pipe body is composed of a spirally wound rectangular tubular hollow strip 2 and a HDPE plastic filler 3, The HDPE plastic filling body 3 is bonded and filled in the side wall gap between the spirals of the helically wound rectangular tubular hollow strips 2, which is characterized in that the pipe wall of the rectangular tubular hollow strips is from the inside to the The outside is composed of a PVC plastic layer 4, a composite adhesive layer 5 and an HDPE plastic layer 6, and the composite adhesive layer 5 is sandwiched between the PVC plastic layer 4 and the HDPE plastic layer 6 and is connected to the PVC plastic layer 4 and the HDPE plastic layer 6. The HDPE plastic layer 6 is glued together.

[0020] When making the HDPE and PVC plastic-plastic composite winding pipe in this embodiment, firstly, a ...

Abstract

The invention relates to plastic tubing that has twisting tube identity. The tube wall is made up from rectangle tube hollow band and HDPE plastic filling material. The feature is that: the tube wall of hollow band is made up of PVC plastic layer, compound glue binding layer and HDPE plastic layer from inside to outside; and the compound glue binding layer is clipped between PVC plastic layer and HDPE plastic layer and sticking to PVC plastic layer and HDPE plastic layer. The invention has the advantages of good chemical resistance, light weight, convenient to connect, economic, no environment pollution, etc.

Description

technical field [0001] The invention relates to a pipe, especially a plastic pipe. Background technique [0002] In drainage pipes such as housing construction and municipal construction projects, a plastic winding pipe is generally used. For example, the Chinese utility model patent ZL01216004.0 discloses a large-diameter hollow strip winding pipe, which is formed by spirally winding a square tubular hollow strip and an adhesive layer side by side. It consists of two layers of pipe walls and a hollow interlayer sandwiched between them. Existing plastic winding pipes are usually made entirely of HDPE plastics (high-density polyethylene plastics), that is, helically wound rectangular tubular hollow strips and each helix that is bonded and filled in the spirally wound rectangular tubular hollow strips. The adhesive layer at the gap between the side walls is HDPE plastic. When manufacturing the winding pipe, the rectangular tubular hollow strip made of HDPE plastic is usuall...
