Composition for preparing air discharging pipeline in double-riser-pipe drainage system

Abstract

The invention relates to a composition for preparing an air discharging pipeline in a double-riser-pipe drainage system. The composition comprises, by weight, 90-100 parts of polyvinyl chloride resinbodies, 0.3-0.5 part of antioxidants, 50-60 parts of fire retardants, 0.5-2 parts of antistatic agents, 2-3 parts of anti-impact agents, 5-10 parts of smoke suppression agents and 0.5-1 part of mildew-proof agents. According to the composition, additives are added into polyvinyl chloride, so that the polyvinyl chloride is improved, the additives and other components are combined by the aid of specific content, so that a water discharging pipe prepared from the composition has high impact resistance and toughness and abrasion resistance, and service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composition for preparing an exhaust pipe in a drainage system. Background technique [0002] At present, the exhaust pipes in the drainage system used in buildings are mainly PVC pipes, and the PVC pipes are mainly polyvinyl chloride, but PVC has problems such as easy decomposition and poor impact resistance, so it is necessary to add various additives to PVC. To improve the performance of polyvinyl chloride, so that it can obtain more excellent performance and adapt to more severe application environments. [0003] However, polyvinyl chloride is an organic matter, and it is easy to generate a large amount of smoke when it is burned. Once a fire breaks out in the building, it is very easy to cause casualties, and the exhaust pipe made of it has poor toughness and poor wear resistance. Therefore be badly in need of inventing and manufacturing a kind of new compositi...
