Abstract

A disclosed noise-reducing muted drainpipe is composed of the following raw materials in parts by weight: 2-3 parts of propolis, 1-2 parts of guanidine sulfamate, 4-6 parts of hollow glass bead, 0.2-0.5 parts of ammonium paratungstate, 1-2 parts of docusate sodium, 1-2 parts of N-ethyl-o / p-toluenesulfonamide, 1-2 parts of calcium fluoride, 1-2 parts of polyvinyl butyral, 0.5-1 parts of cyclohexanehexol, 1-2 parts of decabromodiphenylethane, 2-3 parts of vinyl acetate, 10-13 parts of precipitate barium sulfate, 93-100 parts of polypropylene and 7-10 parts of a composite auxiliary agent. The drainpipe has the mute effect obviously better than the mute effect of other pipes, has the routine draining noise value low to 45 decibel or less, is good in environment-protection property, and also is good in impact resistance, high in toughness and strong in weatherability.

Description

technical field [0001] The invention mainly relates to the field of pipe materials, in particular to a noise-reducing and silent drainage pipe and a preparation method thereof. Background technique [0002] Polypropylene has high crystallinity and regular structure, so it has excellent mechanical properties. The absolute value of the mechanical properties of polypropylene is higher than that of polyethylene, but it is still a relatively low variety in plastic materials, and its tensile strength can only reach 30 MPa or a slightly higher level. Polypropylene with a larger isotactic index has higher tensile strength, but as the isotactic index increases, the impact strength of the material decreases, but it does not change after falling to a certain value. [0003] Temperature and loading rate have a great influence on the toughness of polypropylene. When the temperature is higher than the glass transition temperature, the impact fracture is ductile fracture, and below t...
