Non-structural corrugated pipes are made of simple structure drainage/sewage corrugated pipes through the characteristics of raw material components. This type of corrugated pipes can also be divided into metal bellows and plastic bellows. The cost of metal bellows is relatively high, and the buried time It is easy to rust after a long time, and it is rarely used in municipal drainage\sewage projects, such as patent CN101949477A; plastic bellows are characterized by high quality, light weight, no scaling, small frictional resistance, and long service life. They are the most widely used in recent years. For example, a prestressed plastic bellows and its manufacturing method disclosed in the patent CN101603615A discloses "using recycled plastics, pure recycled plastics, preservatives, anti-aging agents, binders and pigments as raw materials" to make The corrugated pipe has the characteristics of low production cost, good durability, and excellent rigidity. However, a single plastic material has high toughness, large shrinkage, large variable volume, and slight irreversible deformation after the change. Deformation, affect the use effect

Embodiment 1
[0027] Drainage bellows processed by waste mulch are made of the following raw materials by weight, which are melted and extruded by a plastic extruder: 76.5kg of modified waste mulch, 28kg of silicate mineral composition, 7.5kg of fly ash hollow microspheres , Antioxidant 1.8kg, coupling agent 4.2kg, lubricant 3.5kg, compatibilizer 3kg, colorant 0.3kg.
[0028] Wherein, the silicate mineral composition includes: kaolinite, montmorillonite, and zeolite, and the ratio of the three is 1:1:1.
[0029] The modified waste plastic film is obtained by melting and extruding the following components by weight through a plastic extruder: 100 parts of waste plastic film recycling particles, 8 parts of carbon black, 12 parts of talcum powder, 12 parts of calcium carbonate, diluent 3.5 parts, catalyst 1.2 parts.
[0030] The antioxidant is: 2,6-tertiary butyl-4-methylphenol, bis(3,5-tertiary butyl-4-hydroxyphenyl) sulfide or tetrakis [β-(3, 5-tert-butyl-4-hydroxyphenyl) propionate] penta...

Abstract
The invention discloses a method for processing draining corrugated pipe using waste and old mulch film, and belongs to the field of a nonmetal building material technology. The draining corrugated pipe is prepared by a plastic extruder with a fusion extrusion method and employs the following raw materials in part by weight: modified waste and old mulch film, a silicate mineral composition, fly ash hollow cenospheres, an anti-oxidant, a coupling agent, a lubricant, a compatilizer and a pigment. According to the invention, the modified waste and old mulch film is used as the raw material, the silicate mineral composition, the fly ash hollow cenospheres and accessories are added for processing and preparing; the invention has the advantages of low cost, environmental protection and safety. Simultaneously, the silicate mineral combination which is a chemical inertia component with complex structure is added, thereby improving ring stiffness and ring flexibility of the corrugated pipe and better bearing the long-term acid and alkaline sewage impact; the reversible deformability is moderate and the corrugated pipe is not easy to be damaged by corrosion; the fly ash hollow cenospheres are added, thereby improving the ring stiffness of the corrugated pipe, and improving dewatering capability and anti-compression buffer capability of the corrugated pipe.
Description
technical field [0001] The invention relates to a method for processing drainage / sewage underground corrugated pipes, which belongs to the technical field of non-metallic building materials, in particular to a method for processing drainage corrugated pipes by using waste plastic film. Background technique [0002] my country's plastics processing industry has developed into a pillar industry of the national economy with a wide variety and complete categories. However, since plastics cannot be degraded under natural conditions, plastic wastes gradually accumulate, forming serious environmental pollution, that is, the so-called "white pollution". Waste plastics still contain huge renewable resources, and the existence of "white pollution" is a huge waste of limited earth resources. Therefore, the recycling and reuse of waste plastics can not only solve the problem of "white pollution", but also save resources and generate huge economic benefits . [0003] Double-wall corrug...
