Preparation method of pipeline material capable of reducing pipeline brittleness

Abstract

The invention relates to the field of pipelines, and particularly discloses a preparation method of a pipeline material capable of reducing pipeline brittleness. The pipeline material is prepared fromthe following components in parts by weight: 45 to 55 parts of a polypropylene mixture, 32 to 36 parts of a fibre mixture, 20 to 26 parts of a rubber mixture, 12 to 14 parts of octylene, 5 to 8 partsof ethyene-propylene and 15 to 17 parts of calcium carbonate; the polypropylene mixture is prepared from the following components in parts by weight: 28 parts of polypropylene, 8 parts of a talcum powder and 2 parts of polycarbonate; the fibre mixture is prepared from the following components in parts by weight: 25 parts of natural fibres, 17 parts of carbon fibres and 6 parts of aramid fibres; the rubber mixture is prepared from the following components in parts by weight: 21 parts of natural rubber, 6 parts of silica gel, 5 parts of isobutylene rubber and 9 parts of butadiene rubber; the pipeline material comprises 13 parts of the octylene by weight and 7 parts of the ethyene-propylene by weight; the calcium carbonate is a calcium carbonate powder which can enhance the corrosion resistance of a pipeline; the fibre mixture can effectively improve the structural strength of the pipeline and enhance the toughness of the pipeline.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to a method for preparing pipeline materials with reduced pipeline brittleness. Background technique [0002] Plastic pipe refers to the general term for pipes made of plastic materials; plastic pipes have the characteristics of light weight, sanitation and safety, small water flow resistance, energy saving, metal saving, improvement of living environment, long service life, safety and convenience, etc. of favor. Plastic pipes are experiencing rapid development against the background of the great development of chemical building materials. In 2010, the national output of plastic pipes exceeded 8 million tons, of which Guangdong, Zhejiang and Shandong accounted for 42% of the output. Compared with traditional metal pipes and concrete pipes, plastic pipes have more advantages in many fields, and have also been widely promoted. Compared with traditional cast iron pipes, galvanized steel pipes...

Problems solved by technology

Compared with traditional metal pipes and concrete pipes, plastic pipes have more advantages in many fields, and have also been widely promoted. Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, plastic pipes are energy-saving. Material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, long service life, etc., are widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial In the construction, municipal, industrial and agricultural fields such as fluid transportation and agricultural irrigation, the classification of plastic pipes can be distinguished from their materials and main fields of use. From the perspective of different classifications of chemical materials used, plastic pipes can be divided into PVC pipes , polyethylene pipes, polypropylene composite pipes, polybutylene pipes, ABS pipes, etc. HDPE (high density PE), LDPE (low density PE) and other PE pipes are collectively referred to as PE pipes, while PVC-C and PVC-U pipes Collectively referred to as PVC pipes, the PVC piping system was developed the earliest and is currently used in the largest amount. Compared with traditional metal pipes, plastic pipes have light weight, corrosion resistance, high compressive strength, sanitation and safety, small water flow resistance, energy saving, metal saving, and improvement. Living environment, long service life, safety and convenience, but at present, some plastic pipe manufacturers in China have not invested much in product innovation, and there are relatively few new products with high performance, high technology content, and high added value. Similar general-purpose pipes on the market There are many products and middle and low-end products. Nowadays, most pipelines are replaced periodically. The plastic pipeline itself is very brittle, resulting in weak structural strength of the pipeline, which seriously affects the practicability of the pipeline.
