Abstract

The invention belongs to the field of organic polymer materials, and discloses a regenerated modified material specially used for solid wall tubes, and a preparation method and an application thereof. The regenerated modified material specially used for solid wall tubes comprises, by weight, 50-80 parts of a small hollow bottle recovered high-density high density polyethylene material, 100 parts of a chemical barrel recovered high density polyethylene material, 0.2-0.5 parts of an antioxidant 1010, 0.2-0.5 parts of an antioxidant 168, 5-20 parts of high density polyethylene reinforced master batch, 0.1-0.5 parts of a coupling agent and 1-3 parts of a cross-linking agent. The method comprises the following steps: mixing the small hollow bottle recovered high density polyethylene material with the chemical barrel recovered high density polyethylene material, and carrying out melt extrusion in a single-screw upper extruder to obtain a melt mixture; adding other raw materials to a high speed mixer, and mixing to obtain an assistant mixture; and simultaneously adding the melt mixture and the assistant mixture to a double-screw lower extruder, and carrying out blending granulation to obtain the regenerated modified material specially used for solid wall tubes.

Description

technical field [0001] The invention belongs to the field of organic polymer materials, and relates to a special material for solid-wall pipes and its preparation method and application, in particular to a special recycled modified material for solid-wall pipes and its preparation method and application. Background technique [0002] China's urban construction is becoming more and more perfect, and the roads, greening and pipeline networks of new buildings are all over urban and rural areas. In order to avoid excavating roads, greening and water supply and drainage pipe networks when new pipelines such as telecommunications and electric power need to cross built roads, a large number of non-excavation traction pipe technology is used, and this technology is mature. Because the material of power and telecommunication threading pipes requires suitable hardness and good welding performance; there is no requirement for hygienic indicators of materials; theoretically speaking, it...
