Abstract

The invention discloses a PVC pipeline. The pipeline is prepared from raw materials in parts by weight as follows: 50-90 parts of PVC resin, 3-8 parts of titanium dioxide, 1-3 parts of stearic acid, 8-15 parts of chlorinated polyethylene, 10-20 parts of calcium carbonate, 0.3-0.8 parts of PE wax, 0.8-1.5 parts of lead stearate, 3-8 parts of carbon black, 2-5 parts of zinc borate, 5-12 parts of melamine, 12-20 parts of acrylonitrile-styrene, 10-20 parts of dioctyl phthalate, 8-15 parts of methacryloxypropyl trifluoromethoxy-silicane, 1-3 parts of an antibacterial agent, 1-3 parts of an anti-wear agent and 1-3 parts of a toughening agent. The PVC pipeline is prepared through reasonable matching of different raw materials and different usages, the raw materials of the PVC pipeline do not contain harmful substances, cannot do harm to body health and can be naturally decomposed after the used pipeline is wasted, and thus, environmental pollution cannot be caused. The cost of the pipeline is reduced by 15% or more than that of the same type of pipelines sold in the market.

Description

technical field [0001] The invention relates to a PVC pipe and a preparation method thereof, belonging to the technical field of pipe production. Background technique [0002] With the continuous improvement of industrial level, PE and PVC plastic pipes are constantly replacing metal pipes, and are widely used in water supply and drainage fields. The pipeline is favored by people because of its light weight, no rust, low cost and convenient installation. However, most of the cheap raw materials used in existing PVC pipes contain a large amount of harmful chemical components, which will cause harm to human health after decomposition. Furthermore, if these pipes are not used, the raw materials cannot be recycled, and it is difficult to decompose after being discarded, which will cause environmental pollution. The price of healthy and environmentally friendly pipelines is generally high. Contents of the invention [0003] The object of the present invention is to provide a...
