Abstract

The invention relates to a formulation of PVC-U pipes, belonging to the technical field of pipes. The formulation comprises the following raw materials in parts by weight: 100 parts of a PVC resin, 2.0-3.0 parts of an organotin stabilizer, 5.0-10.0 parts of carbon nanotube, 1.0-1.5 parts of a composite anti-aging agent, 2.0-3.0 parts of a lubricant, 2.0-5.0 parts of a composite filler, 3.0-6.0 parts of a processing aid ACR, 5.0-10.0 parts of glass fiber and 0.5-1 part of wood flour. The PVC-U pipe produced by adopting the invention has good toughness while retaining a high impact strength value, can effectively resist foundation settlement, point load and seismic performance, so as to meet the current production and living needs, and achieve environmental protection.

Description

technical field [0001] The invention relates to a formula for PVC-U pipes, belonging to the technical field of pipes. Background technique [0002] PVC material is polyvinyl chloride. It is one of the largest plastic products in the world. It is cheap and widely used. Due to its high chemical stability, it can be used to make anti-corrosion pipes, pipe fittings, oil pipelines, centrifugal pumps and blowers. Polyvinyl chloride hard board is widely used in the chemical industry to make various storage tank linings, corrugated boards for buildings, door and window structures, wall decorations and other building materials. Due to its excellent electrical insulation properties, it can be used in the manufacture of plugs, sockets, switches and cables in the electrical and electronic industries. In everyday life, PVC is used in the manufacture of sandals, raincoats, toys, artificial leather and more! It can be seen that PVC-U pipes are widely used, but with the continuous develop...
