Abstract

A disclosed high-toughness tube for explosion is characterized by comprising the following raw materials in parts by weight: 80-120 parts of PVC resin, 0.2-0.4 part of a liquid stannum stabilizing agent, 0.6-1.0 part of calcium stearate, 1.0-1.4 part of paraffin, 0.5-1.0 part of an acrylic acid processing auxiliary agent, 2.0-5.0 parts of calcium carbonate, 10.0-15.0 parts of a plastic impact-resistant agent and 2.0-3.0 parts of rutile titanium dioxide. Compared with the prior art, the technical scheme has the following advantages: (1) the produced product is low in price, the employed raw materials is less, and the production technology is simple; and (2) the high-toughness tube has relatively high toughness, the toughness is destroyed without generating too much fragments when explosion is performed.

Description

technical field [0001] The invention relates to the field of material science, in particular to a high-toughness pipe material for blasting and a production method thereof. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. Generally, pipes do not have high requirements on toughness, but the pipes used in blasting have high requirements on toughness. During the period of higher blasting strength and higher simulation q...
