Embodiment 1

[0009] When the present invention is actually implemented, a composite silent drainage pipe with a thickness ratio of the inner, middle and outer layers of 1:5:1 can be made from the inner layer of polypropylene material, the middle filler layer and the outer layer of polypropylene material, and the inner layer of polypropylene material And the outer layer of polypropylene material is by weight: trackless copolymerized polypropylene 80%, filler 17%, masterbatch 1.2%, antioxidant GA-800.8%, UV-531 ultraviolet absorber 0.7%, hexabromo Prepared by mixing cyclohexadecane 0.3%.

Embodiment 2

[0011] The present invention can also be made of the inner layer of polypropylene material, the middle filler layer and the outer layer of polypropylene material to make a composite silent drainage pipe with a thickness ratio of inner, middle and outer layers of 1:5:1, the inner layer of polypropylene material and the outer layer of polypropylene material The outer layer is made by weight: 52% trackless copolymerized polypropylene, 42% filler, 2% masterbatch, 12% HP from Ciba Specialty Chemicals, 1.5% UV-P ultraviolet absorber, 0.5 tetrabromobisphenol A % mixing made.

Embodiment 3

[0013] The present invention can be made of the inner layer of polypropylene material, the middle filler layer and the outer layer of polypropylene material to make the composite mute drainage pipe with the thickness ratio of the inner, middle and outer layers being 1:5:1, the inner layer of polypropylene material and the outer layer of polypropylene material The layers are all calculated by weight: 20% trackless copolymerized polypropylene, 70% filler, 3% masterbatch, 3% CF-120 complex vitamin E antioxidant, 2% UV-9 ultraviolet absorber, 2% decabromo Prepared by mixing 2% phenyl ether.

[0014] The silent drainage pipe of the present invention meets the national standard after testing, and has the following advantages:

[0015] 1) Excellent mute effect: the energy of sound waves is absorbed by high-density special molecular structure materials, and the mute effect is obviously better than other pipes. According to the test of relevant national departments: the noise value of ...

Abstract

The invention relates to a mute drainage pipe, which effectively solves the problems of large noise, poor high temperature resistance and poor chemical corrosion resistance of the traditional drainage pipe. In the technical scheme for solving the problems, a multi-layer compound is made of a polypropylene material inner layer, a middle packing layer and a polypropylene material outer layer, wherein the thickness ratio of the polypropylene material inner layer to the middle packing layer to the polypropylene material outer layer is 1:5:1; the polypropylene material inner layer and the polypropylene material outer layer are made by mixing the following components: 17-87wt% of polypropylene random copolymer, 11-80wt% of packing, 0.5-3wt% of color master batch, 0.5-3wt% of antioxygen, 0.5-2wt% of ultraviolet absorber and 0.1-2wt% of fire retardant, wherein the total amount is 100 percent. Except the characteristics of chemical corrosion resistance, heat resistance and impact resistance just like a common plastic pipe, the drainage pipe also has the biggest characteristic of good muting effect, the noise is reduced by 20dB in comparison with the common plastic pipe, the noise is reduced by 10dB in comparison with a cast iron pipe.

Description

1. Technical field [0001] The invention relates to a silent drainage pipe. 2. Background technology [0002] With the continuous improvement of living standards, people have higher and higher requirements for the living environment of buildings. Noise pollution has become the pollution that has the greatest impact on human life after air pollution. According to statistics, the current urban noise intensity has increased by 4% compared to 1956. As one of the main noise sources of civil buildings, drainage noise has seriously affected people's daily life, and people expect to have a safe, healthy and comfortable indoor living space. According to the provisions of the national standard GBJ118-88 "Code for Design of Sound Insulation of Civil Buildings": (taking residential buildings as an example) the noise in the bedroom at night should not exceed 30dB, and the maximum should not exceed 40dB. In the actual test, the noise generated by most common drainage pipes and fittings on...
