Anti-scaling plastic pipe with far infrared radiation function and preparation method thereof

Abstract

The invention relates to an anti-scaling plastic pipe with a far infrared radiation function and a preparation method thereof. The pipe comprises a far infrared radiation layer, a polyolefin resin layer and an anti-scaling layer which are sequentially arranged from outside to inside. The far infrared radiation layer is formed by extrusion molding of a far infrared radiation composite material, thefar infrared radiation composite material is prepared from the following components in parts by mass: 100 parts of heat-resistant polyethylene and 1 to 10 parts of functional master batch, the polyolefin resin layer is formed by extrusion molding of a heat-resistant polyethylene material, the anti-scaling layer is formed by extrusion molding of an anti-scaling composite material, and the anti-scaling composite material is prepared from the following components in parts by mass: 100 parts of ultra-high molecular weight polyethylene and 1 to 10 parts of fluorine-containing organic silicon modified PE master batch. According to the preparation method, three-layer co-extrusion is carried out by adopting three extruders, and the anti-scaling plastic pipe with the far infrared radiation function is obtained after vacuum sizing and cooling shaping. The problems that the inner wall of an existing polyolefin pipeline is prone to scaling, and the heat radiation efficiency is low are solved.

Description

Technical field [0001] The invention relates to the technical field of functional plastic pipes and their preparation, in particular to an anti-scaling plastic pipe with far-infrared radiation function and a preparation method thereof. Background technique [0002] Low-temperature floor radiant heating is widely used in building system climate regulation by virtue of its advantages such as "uniform temperature distribution, space saving, and comfort", especially in the heating market at the end of the building system. [0003] However, after the floor heating pipeline has been used for several heating seasons, there will be a large amount of slime, bacteria and scale inside the pipeline, which will adhere to the inner wall of the pipeline, forming a blockage of the pipeline, resulting in poor water circulation and insufficient heat dissipation, which seriously affects the heating temperature and effect; On the other hand, due to the low thermal conductivity of floor heating pipes, ...

AI Technical Summary

Problems solved by technology

[0003] However, after the floor heating pipeline has been used for several heating seasons, there will be a lot of slime, bacteria and scale inside the pipeline, which will adhere to the inner wall of the pipeline and form a pipeline blockage, resulting in poor water circulation and insufficient heat dissipation, seriously affecting the heating temperature and effect; On the other hand, due to the low thermal conductivity of the floor heating pipe, slow heat transfer and low heat exchange efficiency, a large amount of heat energy will be wasted on the water supply and return path, and no effective heat radiation transfer will be formed at the end (ground)

Therefore, the above two situations are a waste of energy and inefficient use for radiant floor heating, which will also greatly affect the health and comfort of radiant floor heating
