Abstract

The invention provides a manufacturing method for an anti-aging PVC tubular product. The anti-aging PVC tubular product comprises the following components in parts by weight: 4-6 parts of a composite stabilizer, 0.5-1.5 parts of a lubricant, 7-8 parts of filler, 3 parts of a coloring agent, 8-10 parts of light calcium carbonate, 6 parts of titanium dioxide, 3 parts of a whitening agent, 2 parts of a flexibilizer, 1-2 parts of a stabilizer, 0.1-0.5 part of an antioxidant and 90-100 parts of PVC resin. The anti-aging PVC tubular product provided by the invention is simple to prepare, the antibacterial capacity is increased, and the product is more excellent in notch impact strength, tensile strength, bending strength, flexural modulus and elongation at break, is relatively long in service life and is more anti-aging.

Description

technical field [0001] The invention relates to the technical field of PVC pipes, in particular to a method for manufacturing anti-aging PVC pipes. Background technique [0002] PVC is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. It is the second most used synthetic material worldwide. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption average 1.4 million tons. PVC pipe (PVC-U pipe) rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and then extruded by hot pressing. It is the earliest plastic pipe that...
