Mining antistatic and flame retardant PVC tube stock and preparing method thereof

Abstract

The invention discloses a mining antistatic and flame retardant PVC tube stock and a preparing method thereof. The mining antistatic and flame retardant PVC tube stock is prepared from, by weight, 74-88 parts of polyvinyl chloride, 32-46 parts of montmorillonite, 8-16 parts of pentaerythritol-dihydrogenphosphate melamine, 18-30 parts of graphene oxide, 5-10 parts of 2-ethylhexylstearate, 3-7 parts of basic nickel carbonate, 6-11 parts of brominated paraffin, 2-4 parts of glyzinc, 1-2 parts of magnesium stearate, 10-15 parts of zirconium hydroxide, 12-19 parts of chloro-methoxy fat diethylene glycol dinitrate and 14-22 parts of pandermite powder. According to the mining antistatic and flame retardant PVC tube stock and the preparing method thereof, an inorganic flame retardant composed of basic nickel carbonate, zirconium hydroxide and pandermite powder is adopted to compound with pentaerythritol-dihydrogenphosphate melamine, an organic flame retardant composed of brominated paraffin, the PVC stock is subjected to flame retardant modification by polyaminopropyl / silsesquioxane micro powder and chloro-methoxy fat diethylene glycol dinitrate, not only can an oxygen index of the material remarkably be increased, but also the mechanical strength, and anti-aging performance and weather resistance of the material can be improved.

Description

technical field [0001] The invention relates to a PVC pipe material and a preparation method thereof, in particular to a mine-used antistatic and flame-resistant PVC pipe material and a preparation method thereof. Background technique [0002] Montmorillonite is a typical natural clay mineral, which has the advantages of high reserves, various types, low price and excellent structure. Montmorillonite also has good dispersion properties, and can be widely used in the polymer material industry as an additive for nano-polymer polymer materials to improve mechanical properties, dimensional stability, thermal stability and gas barrier properties, thereby enhancing polymer properties. The role of comprehensive physical properties, while improving the processing performance of materials, has broad application prospects. [0003] Zheng Yuying and Peng Chao used montmorillonite as the main raw material in their article "Research and Development of PVC-U / Montmorillonite Nanocomposite...

AI Technical Summary

Problems solved by technology

However, the composite pipes prepared in the above literature have the disadvantages of large surface resistance and poor antistatic properties. Once the pipe surface is rubbed, static electricity will be generated and gathered on the pipe surface. If it is used in coal mine production operations, it may cause fire when the static electricity is discharged. and gas explosion, unable to meet the requirements for the use of mining pipes, limiting its application range

In addition, the flame retardant properties of the composite pipes prepared in the above literature are not satisfactory.
