Abstract

The invention relates to a high polymer material for a pipeline and a preparation method of the high polymer material. The high polymer material comprises 4-8 parts of urea resin, 3-10 parts of polyisocyanurate, 2-6 parts of polyisobutene, 3-8 parts of brominated butyl rubber, 3-6 parts of dicyclohexyl phthalate, 2-5 parts of glass fiber, 4-7 parts of polytetrafluoroethylene, and 3-8 parts of furan resin. The preparation method comprises the following steps: step 1, taking all of the components, feeding the components in an agitator tank, and heating the agitator tank till the components are smelted; step 2, conducting twin-screw extrusion on the uniformly stirred material in the step 1 with a twin-screw extrusion machine, extruding out the material and granulating the material to obtain the high polymer material for the pipeline. The prepared high polymer material for the pipeline has the advantages of being high in tensile strength and shock strength.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a polymer material for pipelines and a preparation method thereof. Background technique [0002] Compared with traditional metal pipes, polymer material pipes have the characteristics of light weight, corrosion resistance, high compressive strength, sanitation and safety, small water flow resistance, energy saving, metal saving, improved living environment, long service life, and convenient installation. It has won the favor of the pipeline engineering industry and occupied a very important position, forming an irresistible development trend. Pipes made of polymer materials have been widely used at home and abroad in urban water supply, urban drainage, building water supply, building drainage, hot water supply, heating and heating, building rainwater drainage, urban gas, agricultural drainage and irrigation, chemical fluid transportation and wires, Cable sheathing and other field...
