▎ 摘　　要

NOVELTY - An antibacterial synthetic resin composition comprises 100 pts. wt. synthetic resin chosen from vinyl chloride, polyethylene, polystyrene, polyester, polypropylene and polycarbonate, 5-10 pts. wt. impact modifier chosen from methacrylate butadiene styrene (MBS), chlorinated polyethylene (CPE) and acrylonitrile butadiene styrene terpolymer (ABS), 5-15 pts. wt. mineral powder coated by surface treatment with terpene-containing essential oil having antibacterial properties, and 1-20 pts. wt. graphene as graphene powder or graphene solution. The mineral powder is at least one chosen from elvan, germanium, zeolite, volcanic stone, illite, bentonite and sericite. The essential oil is chosen from lavender oil, rosemary oil, sulfur oil, citronella oil, lemon oil, cedarwood oil, clove oil, basil oil, bergamot oil, eucalyptus oil, chamomile oil, jasmine oil, and cinnamon oil. USE - Antibacterial synthetic resin composition for producing synthetic resin pipe (claimed) e.g. water supply pipes, sewer pipes and sewage pipes used for supplying drinking water. ADVANTAGE - The composition provides synthetic resin pipe having lightweight, improved antibacterial properties and durability, ensures increased fluid flow, and improves environment by preventing microorganisms or bacteria from easily propagating and improving hygiene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for synthetic resin pipe, which is prepared by weighing and preparing the antibacterial synthetic resin composition, melting the resin composition, extruding the molten antibacterial synthetic resin composition to form synthetic resin pipe having a pipe structure having a preset diameter, cooling the synthetic resin pipe of the extruded pipe structure, and cutting the synthetic resin pipe into a preset length. The synthetic resin contains a blended composition of main material and additive material in a weight ratio of 1-1.2:0.1-0.3. The main material includes vinyl chloride, polyethylene, polystyrene, polyester, polypropylene and/or polycarbonate. The additive material is polyoxymethylene (acetal) resin having excellent dimensional stability, self-lubrication and resistance to shock and vibration.
