NOVELTY - A plastic tube material comprises modified filler, polyvinyl chloride resin powder, stearic acid monoglyceride, zinc borate, ( gamma )-methacryloyloxypropyltrimethoxysilane, melamine, chlorinated paraffin, calcium carbonate, hydrogenated castor oil, hexadecyl 3,5-di-tert-butyl-4-hydroxy-benzoate, ammonium polyphosphate, graphene, tricresyl phosphate and toluene cresyl phosphate, in preset weight ratio. The modified filler contains barite powder, calcite powder, barium petroleum sulfonate, ( gamma )-aminopropyltrimethoxysilane, 2,6-di-tert-butyl-4-methylphenol and dimethyl phthalate. USE - Plastic tube material (claimed). ADVANTAGE - The plastic tube material has high intensity, excellent flame retardance and ultraviolet light resistance effect. DETAILED DESCRIPTION - A plastic tube material comprises 80-140 pts. wt. modified filler, 150-160 pts. wt. polyvinyl chloride resin powder, 1-2 pts. wt. stearic acid monoglyceride, 18-22 pts. wt. zinc borate, 1.2-3.4 pts. wt. ( gamma )-methacryloyloxypropyltrimethoxysilane (KH570) as silane coupling agent, 1-3 pts. wt. melamine, 6-8 pts. wt. chlorinated paraffin, 10-20 pts. wt. calcium carbonate, 2-3 pts. wt. hydrogenated castor oil, 1.5-2.5 pts. wt. hexadecyl 3,5-di-tert-butyl-4-hydroxy-benzoate (UV-2908) as ultraviolet light stabilizing agent, 2-3 pts. wt. ammonium polyphosphate, 1-2 pts. wt. graphene, 1-2 pts. wt. tricresyl phosphate and 1-2 pts. wt. toluene cresyl phosphate. The modified filler comprises 20-25 pts. wt. barite powder, 10-30 pts. wt. calcite powder, 0.5-1.2 pts. wt. barium petroleum sulfonate, 1.5-2.5 pts. wt. ( gamma )-aminopropyltrimethoxysilane (KH540) as silane coupling agent, 2.5-5 pts. wt. 2,6-di-tert-butyl-4-methylphenol (BHT) as antioxidant, 0.8-1 pts. wt. potassium aluminum sulfate, 1-2 pts. wt. aluminum powder, 2-4 pts. wt. dimethyl phthalate and 1-2 pts. wt. dioctyl phthalate. The modified filler is obtained by mixing barite powder and calcite powder uniformly, calcining at 700-750 degrees C for 1-2 hours, taking out and cooling the mixture, stirring the mixture using 12-18% hydrochloric acid for 2-3 hours, filtering, washing using deionized water, drying, mixing barium petroleum sulfonate, ( gamma )-aminopropyltrimethoxysilane, 2,6-di-tert-butyl-4-methylphenol, potassium aluminum sulfate, aluminum powder, dimethyl phthalate and dioctyl phthalate uniformly, adding preset amount of water, stirring for 30-40 minutes at 50-60 degrees C, drying and crushing. An INDEPENDENT CLAIM is included for manufacture of plastic tube material, which involves weighing the raw materials, adding polyvinyl chloride resin powder, chlorinated paraffin and calcium carbonate in an extruder, stirring for 3-5 minutes at 180-190 degrees C, adding modified filler, stearic acid monoglyceride, zinc borate, ( gamma )-methacryloyloxypropyltrimethoxysilane, melamine, hydrogenated castor oil, hexadecyl 3,5-di-tert-butyl-4-hydroxy-benzoate, ammonium polyphosphate, graphene, tricresyl phosphate and toluene cresyl phosphate, heating at 170-185 degrees C for 14-16 minutes, stirring at 170-175 degrees C for 12-14 minutes, cooling at 30-40 degrees C, and molding.
