Embodiment Construction

[0024] In order to better understand the content of the present invention, the following will be further described in conjunction with specific examples.

[0025] see Figure 1 to Figure 4 As shown, the multi-layer composite seamless all-plastic pipe of the present invention has a pipe wall including a first end face 1 and a second end face 2, and the first end face 1 and the second end face 2 are completely butted and fixed.

[0026] In a specific embodiment of the present invention, both the first end face 1 and the second end face 2 are inclined end faces, and the inclination angles of the first end face 1 and the second end face 2 are complementary angles to each other.

[0027] In a specific embodiment of the present invention, the first end surface 1 and the second end surface 2 are fixed by welding.

[0028] In a specific embodiment of the present invention, the hierarchical structure of the pipe wall includes a plastic printing layer 3, a first adhesive layer 4, a wat...

Abstract

The present invention provides a multi-layer composite seamless overall plastic tube, the tube wall comprises a first end surface and a second surface, both are slant end surface, and the slant angles are complementary angle relatively, the first and the second end surface are completely matched and opposite joint fixed, the hierarchical structure of the tube wall comprises a plastic printing layer, a first binding layer, a water-oxygen isolation layer, a second binding layer and a plastic heat sealing layer, the first binding layer bonds the plastic printing layer and the water-oxygen isolation layer, the second binding layer bonds the water-oxygen isolation layer and the plastic heat sealing layer, the invention also provides a preparation technique for the multi-layer composite seamless overall plastic tube, the inventive multi-layer composite seamless overall plastic tube external appearance has no appreciable soldering joint, high overlap joint intensity, durable ability, beautiful appearance, good handfeel, easy print, thus overcoming defects of having soldering joint of the multi-layer composite overall plastic tube, and defect of simplex function of single layer extrusion tube is overcome by the multi-layer compound structures.

Description

technical field [0001] The present invention relates to the technical field of pipes, more specifically to the technical field of multilayer composite pipes, in particular to a multilayer composite seamless all-plastic pipe and its preparation process. Background technique [0002] In modern life, pipes play an increasingly important role in various fields. With the continuous development of new materials, various new types of all-plastic pipes have appeared. In particular, the multi-layer all-plastic composite pipe plays an extremely important role in the packaging fields of modern cosmetics, food, and medicine by virtue of its high barrier property to water vapor and air, hygienic and non-toxic. [0003] Although the existing all-plastic multi-layer composite pipe can meet the needs of most occasions, there is an overlapping weld seam on the outer wall of the pipe, which affects the printing effect of the appearance, and the hand feels hard, and the production process is s...
