Graphene coating glass fiber reinforced and modified PVC tube special for coal mine well and manufacture method thereof

Abstract

The invention discloses a graphene coating glass fiber reinforced and modified PVC tube special for a cola mine well. The PVC tube is prepared from, by weight, 100 parts of PVC resin, 10-12 parts of ethylene propylene diene monomer, 14.8-15.8 parts of glass fiber, 20-21 parts of montmorillonite, 0.8-1.2 parts of barium stearate, 3.9-4.5 parts of europium oxide, 3-4 parts of nano diamond powder, 5-7 parts of graphene, 2-4 parts of isothiazolinone, 5-6 parts of silane coupling agent KH550, 0.3-0.5 part of carvone and a proper amount of water. According to the graphene coating glass fiber reinforced and modified cola PVC tube special for the mine well, the graphene coats on the surface of the glass fiber in a coupling mode through silane coupling agent KH550 to be used as a reinforcing material, the montmorillonite is modified and treated by europium oxide and nano-crystalline diamond powder to be used as modifying filler, other effective auxiliaries are added so as to prepare the PVC tube used in the coal mine well environment, and the PVC tube has good antistatic and impact resistant properties and is high in tensile strength and excellent in heat-conducting property.

Description

technical field [0001] The invention relates to the technical field of PVC pipes and preparation methods thereof, in particular to a graphene-coated glass fiber-reinforced and modified PVC pipe special for coal mines and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) resin is one of the most widely used and used thermoplastic resins in our daily life. It has light weight, good insulation, difficult to burn, high mechanical properties, low price, abundant raw material Mature and other characteristics, so it is widely used in the field of coal mine pipe materials and other fields. However, it still has some insurmountable shortcomings such as poor impact performance and poor thermal stability. In order to overcome the above defects of polyvinyl chloride, many scholars have conducted a lot of research on PVC toughening modification. At present, glass fiber has gradually entered the In the vision of PVC modification researchers, for example...

Problems solved by technology

However, due to the high insulation of PVC, its surface resistance is as high as about 1014Ω. This insulating property often causes static electricity to be generated in the production, storage, transportation and use of PVC products, which may easily cause explosion accidents, but there is no research in the literature. Antistatic modification. In addition, due to the poor compatibility between glass fiber and PVC, the impact resistance, shear strength, and tensile strength of the prepared PVC composite material cannot meet the requirements of coal mine pipes. Index, and poor wear resistance, antibacterial, anti-corrosion, the above defects limit the popularization and application of polyvinyl chloride in coal mines
