Anti-scaling drainage and sewage pipe, pipe fitting and preparation method thereof

Abstract

The invention belongs to the technical field of plastic pipes, and in particular relates to an anti-scaling drainage and sewage pipe, a pipe fitting and a preparation method thereof. The pipe includes an inner layer and an outer layer, and the outer layer includes the following raw materials in parts by weight: PVC resin 100 3-8 parts of calcium zinc stabilizer; 0.5-20 parts of nanomaterials; 0.5-15 parts of impact materials; 0.1-2.0 parts of lubricants; 0.-8 parts of titanium dioxide; The layer includes the following raw materials in parts by weight: 0-100 parts of PVC resin; 3-8 parts of calcium-zinc stabilizer; 1-100 parts of bright resin; 0.5-50 parts of self-lubricating material; 0.5-20 parts of nanometer material; 0.5-15 parts of material; 0.1-2.0 parts of lubricant; 0.1-15 parts of antibacterial material; 1-35 parts of ABS. In the inner tube, add bright resin to reduce the friction coefficient of the inner tube, reduce scaling, and then combine it with self-lubricating resin to prevent scaling. At the same time, add antibacterial materials to prevent bacterial growth and scaling, and in the present invention, It also contains engineering plastic ABS, which improves the wear resistance of the pipe on the premise of preventing scaling.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, and in particular relates to anti-scaling drainage and sewage pipes, pipe fittings and a preparation method thereof. Background technique [0002] At present, PVC drainage pipe fittings are one of the pipes with the largest demand for plastic pipes in China. Due to their cheap price, convenient installation, convenient maintenance, good flame retardant performance, long service life, and ecological environmental protection, they are mainly used in civil construction projects. A pipe for drainage and sewage. Although PVC pipes have better anti-fouling performance than ductile iron pipes and cement pipes, they are prone to fouling after long-term use. There are many bacteria in the pipe, and the smell is strong, and it is easy to spread diseases, such as coronavirus, which affects the environment; and when PVC pipes are used in high-rise buildings, the drainage and wear resistance are poor, ...

Problems solved by technology

Although PVC pipes have better anti-fouling performance than ductile iron pipes and cement pipes, they are prone to fouling after long-term use. There are more bacteria in the pipe, the smell is strong, and it is easy to spread diseases, such as coronavirus, which affects the environment; and when PVC pipes are used in high-rise buildings, the drainage and wear resistance are poor, and the service life of the pipes is shortened

[0003] Patent CN103589067B discloses a composite plastic with antiscaling effect and its preparation method, which uses polyacrylic acid, hydroxyethylidene diphosphonic acid, etc. %, the composite plastic with anti-scaling effect prepared by it, but in this patent, the raw materials and preparation process in its formula are not suitable for the preparation of pipes
