Abstract

The invention provides an impact-resistant modified polyvinyl chloride (PVC-M) pipe material for a coal mine. The pipe material is prepared by adding a nanoscale antistatic reinforcing and tougheningmaterial and a flame-resistant material. The impact-resistant modified polyvinyl chloride (PVC-M) pipe material for the coal mine has the advantages that by fully utilizing the advantages of high strength, low cost, convenient material taking and easy processing, the electrical conductivity of nanoscale conductive carbon black and the synergistic flame-retardant smoke suppression effect of tricresyl phosphate or aluminum hydroxide and cooperating with the toughening and reinforcing material, the pipe material achieves the purpose of the safe use in the field of coal mine medium conveying and has an antistatic function, and the antistatic capacity of a pipeline is improved, so that the pipeline is suitable for the application of an underground system of the coal mine; the pipe material hasantistatic, flame-resistant, inner pressure-resistant and impact-resistant properties, compared with a traditional plastic pipeline, the pipeline is more durable and safer, and especially suitable forthe work environment, flame retardance, impact resistance and other fields which have requirements for the anti-static electricity, the use safety can be effectively improved, and the possibility ofthe safety accident injury caused by pipe bursting and air leakage due to accidental damage is reduced.

Description

technical field [0001] The invention relates to an impact-modified polyvinyl chloride (PVC-M) pipe technology used in the coal mine field, in particular to a formula design technology for blending and modifying PVC resin by using polymer modified materials, using antistatic agents, Reinforcing agent, functional modifier, impact modifier, flame retardant material, after blending and modification to obtain mixed ingredients, and then extruded to prepare impact-modified polyvinyl chloride (PVC-M) pipes for coal mines . Background technique [0002] Traditional PVC-U pipes are widely used in the fields of water supply and drainage, and have certain advantages such as acid resistance, alkali resistance, corrosion resistance, and internal pressure resistance. However, PVC-U pipes have poor impact resistance, are not antistatic, tend to become brittle at low temperature, have insufficient flame retardancy, produce smoke when burned, are not resistant to aging, and are prone to sta...
