Problems solved by technology

[0002] Most of the water pipes and drainage pipes currently used are PVC plastic pipes. The materials used to make plastic pipes are divided into two types. One is made of PVC resin plus ordinary calcium carbonate as the main raw material; the other is to use recycled PVC and calcium carbonate are the main raw materials. The cost of pipes made of the former is very high, and other physical and chemical properties such as strength, toughness, corrosion resistance, heat resistance, etc. are average, and the latter is made of the material. The pipe material cost is low, but the color is not white, the internal and external smoothness is rough, and the physical and chemical properties such as strength, toughness, corrosion resistance, and heat resistance are poor.

Abstract

The present invention discloses a production method for a PVC-U nanocomposites drainpipe. The pipe wall of the drainpipe consists of an inner layer (3), a sandwich layer (2) and an outer layer (1). The present invention is characterized in that each layer is formed by feed preparation, high speed mixing, low speed mixing, high speed mixed squeezing out, then molding by the same complex mould, and the finished product is got by cooling size, hauling, fixed length cutting; the inner and the outer layer materials consist of PVC resin, plain calcium carbonate, nano-size calcium carbonate, PVC composite stabilizer, PE wax, stearic acid, titanium white powder, and ACR, the core material compared with the outer layer material adopts the reclpurposeed PVC reclpurposeed material to replace the PVC resin, and the other materials are fixed. The present invention greatly enhances the solidity, toughness, stain resistance, and heat resistance etc. of the physical and chemical properties of the pipe material, when the solidity and the service property of the pipe material are ensured, the production cost of the pipe material is reduced, the color and luster of the pipe material is whiter, and the figure is more beautiful.
