Problems solved by technology

In addition, the softness of impact-resistant polypropylene itself is poor, and it is more difficult to install when the wall thickness is large, so it is not suitable for floor heating
[0005] From the performance point of view, the polybutene pipe itself also has some shortcomings, and the negligence in construction can easily cause the rupture of the pipe.
The oxygen permeability of polybutene pipes is relatively high, and it is easy to cause corrosion of the system when used in hot water pipes, so it is not suitable for heating systems
The most important thing is that the price of polybutene is too high for users to afford

Embodiment

[0025] Embodiment: 100 parts of ultra-low density polyethylene (high temperature resistant non-crosslinked polyethylene), nano silicon dioxide SiO 2 20 parts, 0.1 part of antioxidant.

[0026] 1. Process flow:

[0027] Drying of raw materials (feed the raw materials into the dryer, the dryer sends air through the windmill, blows it to the electric heating tube in the heating cylinder, and then controls the temperature of the air supply temperature by the temperature controller and circulates it evenly in the drying barrel to achieve the original drying in the barrel The purpose of drying) → feeding (feeding the dried material into the hopper is done by the automatic suction machine, there is a material level switch in the material, when the raw material is lower than its lower limit, the material is sucked into the hopper) → 65 / 33 Single extrusion (heat up the barrel and mold, then start the main engine, and extrude the raw material to the mold) → mold (when the material is...

Abstract

The present invention relates to one kind of heat resistant reinforced polyethylene pipe and its making process. The materials for the polyethylene pipe includes ultralow density polyethylene 100 weight portions, nanometer silica 20 weight portions and antioxidant 0.1 weight portion. The polyethylene pipe is made through the steps of stoving the materials, feeding, extruding, molding, vacuum sizing, cooling, drawing, ink jetting printing, winding and product packing. It is made in an automatically controlled production line in high production speed and high product quality.

Description

technical field [0001] The invention relates to a non-crosslinked pipe material and a preparation method thereof, belonging to the technical field of polymer compositions. Background technique [0002] In recent years, the application of my country's plastic pipe industry in various industries has developed rapidly. It has played a role in promoting the rise of the plastic pipe industry with its obvious advantages such as energy saving, space saving and higher comfort, especially in the promotion and application of floor heating. The application of plastic pipes is developing rapidly, and the amount of pipes used for floor heating is similar to that of tap water. At present, my country's floor heating pipes are mainly PEX (cross-linked polyethylene) pipes, PP-R (random copolymer polypropylene), PP-B (impact-resistant polypropylene) and PB (polybutene-1) pipes. There are many disadvantages in the use of these pipes: [0003] Cross-linked polyethylene pipe: Cross-linked polye...
