FRPP ultra-silence drain pipe

Abstract

The invention belongs to the technical field of drainage pipes, and particularly relates to an FRPP ultra-silence drainage pipe which is formed by compounding an inner layer, a core layer and an outer layer, and the core layer is located between the inner layer and the outer layer; the inner layer is prepared from the following raw materials in percentage by weight: 99.3 to 99.7 percent of polypropylene and 0.3 to 0.7 percent of color master batch; the core layer is prepared from the following raw materials in percentage by weight: 48 to 52 percent of polypropylene, 28 to 32 percent of calcium carbonate, 16.5 to 19.5 percent of barium sulfate and 0.5 to 3 percent of glass fiber; the outer layer is prepared from the following raw materials in percentage by weight: 99.3 to 99.7 percent of polypropylene and 0.3 to 0.7 percent of color master batch. The FRPP ultra-silence drain pipe is manufactured by adopting a three-layer co-extrusion one-time forming processing technology, is good in noise reduction effect, can achieve a silence effect, is small in glass fiber consumption, is low in production cost, reduces the exploitation of raw materials from the source, reduces the energy consumption and dust pollution, and improves the production efficiency. Permanent injury, namely silicosis, to workers in a working environment for a long time is avoided, and the requirements of industrial production can be met.

Description

Technical field [0001] The invention belongs to the technical field of drainage pipes, in particular to an FRPP ultra-quiet drainage pipe. technical background [0002] With the rapid development of real estate industry and modern science and technology, human beings put forward higher requirements for the design and construction of modern residential buildings. At present, the master bedroom in middle and high-grade residential buildings in China is generally equipped with an independent bathroom. However, while enjoying the private space, the noise generated by the bathroom has been bothering people, especially the elderly, infants and young children, the mentally weak and so on. According to "Code for Sound Insulation Design of Civil Buildings" (GBJ118-88), "Bedroom ≤40 dB", according to the survey of relevant industry, when the toilet upstairs flushes, the noise generated downstairs far exceeds this standard. [0003] At present, the noise reduction effect of drainage pipes o...

Problems solved by technology

[0003] At present, the noise reduction effect of drainage pipes on the market is not good, and in order to improve the noise reduction effect of drainage pipes, glass fibers are added to modify the pipes when making pipes, but the amount of glass fibers added is relatively large, generally 10~ 30%, the amount of glass fiber added to the drainage pipes produced by our company before is 20% (weight percentage). Due to the large content of glass fiber, the rough surface of the pipe will cause wear and corrosion to the equipment, and there will be glass filaments on the surface of the finished product. Workers or construction workers will cause injury; and the production cost is high. From the source, a large amount of raw materials need to be mined, energy consumption and dust pollution are relatively large, which will cause permanent damage to workers who have been in the working environment for a long time--silicosis Disease, not up to the requirements of industrial production
