阅读说明：本技术 一种超静音pp排水管材 (A kind of super-silent pp drainage pipe ) 是由 刘良雨 刘良言 刘占彪 于 2019-08-16 设计创作，主要内容包括：本发明涉及一种超静音pp排水管材,由内表层、外表层和芯层组成,所述的芯层位于内表层和外表层之间,所述的内表层和外表层由聚丙烯材料制成,所述的芯层由聚丙烯、碳酸钙、硫酸钡、玻璃纤维母料制成；本发明的管材采取三层共挤工艺制造,管壁内外层密度差使得管材具有良好的吸声功能,管壁对震动惰性大,可以有效抑制系统震动,解决结构传播噪音。(The present invention relates to a kind of super-silent pp drainage pipes, it is made of endosexine, extexine and sandwich layer, the sandwich layer is between endosexine and extexine, the endosexine and extexine is made of polypropylene material, and the sandwich layer is made of polypropylene, calcium carbonate, barium sulfate, glass fibre masterbatch；Tubing of the invention takes three-layer co-extruded technique to manufacture, and tube wall ectonexine density contrast makes tubing have good sound absorption function, and tube wall is big to vibration inertia, effectively system can be inhibited to shake, and solves structure-borne noise.)

1. a kind of super-silent pp drainage pipe, it is characterised in that: be made of endosexine, extexine and sandwich layer, the sandwich layer position Between endosexine and extexine, the endosexine and extexine are made of polypropylene material, the sandwich layer by polypropylene, Calcium carbonate, barium sulfate, glass fibre masterbatch are made.

2. a kind of super-silent pp drainage pipe as described in claim 1, it is characterised in that: the sandwich layer is by polypropylene 80- 100 parts, 15-20 parts of calcium carbonate, 8-12 parts of barium sulfate, 10-20 parts of glass fibre masterbatch compositions.

Technical field

The invention belongs to tubing technical fields, and in particular to a kind of super-silent pp drainage pipe.

Background technique

With the continuous improvement of living standards, people to building living environment requirement it is also higher and higher, noise pollution at To influence maximum pollution to human lives after the air pollution, and draining noise be the main noise source of civil buildings it One, in construction drainage, it is full of air in pipeline, when draining, existing air was that the sound wave of medium transmits, and has water and solid miscellaneous The noise that the dynamic noise of mass flow and the pipe vibration generated to the shock of tube wall generate；Water flow flows through tubing, especially in drainage At connector and change direction, sound wave is generated in pipe, space is reached by air vibration, these vibration transmissions to pipe laying institute Wall on, by solid shake sound wave reach adjacent space, seriously affect the comfort of room stay；Therefore, one is developed Kind can be effectively reduced the Silent drain pipe of noise to solve the above problems.

Summary of the invention

The purpose of the invention is to overcome the deficiencies in the prior art, and provide that a kind of intensity is high, noise can be effectively reduced Drainage pipe.

The object of the present invention is achieved like this: a kind of super-silent pp drainage pipe, by endosexine, extexine and sandwich layer group At between endosexine and extexine, the endosexine and extexine are made the sandwich layer of polypropylene material, described Sandwich layer be made of polypropylene, calcium carbonate, barium sulfate, glass fibre masterbatch.

The sandwich layer is by 80-100 parts of polypropylene, 15-20 parts of calcium carbonate, 8-12 parts of barium sulfate, glass fibre masterbatch 10- 20 parts of compositions.

Beneficial effects of the present invention: tubing of the invention takes three-layer co-extruded technique to manufacture, tube wall ectonexine density official post Obtaining tubing has good sound absorption function, is added to long glass fibres in the raw material of sandwich layer, improves the density of tube wall, make tube wall With good deadening, while the intensity of tubing is improved, effectively prevented this because hitting and the cumulative production of water flow noise Noise of the air borne without decaying in raw sewage pipe；Tubing elasticity modulus itself is very low, and tubing attenuating structure propagates noise Effect it is obvious, the density of tube wall is larger, to vibration inertia it is big, effectively system can be inhibited to shake, solve structure-borne noise.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of super-silent pp drainage pipe of the present invention.

In figure: 1, extexine 2, sandwich layer 3, endosexine.

Specific embodiment
