Abstract

The invention relates to a composition used for manufacturing a water draining pipeline in a double-vertical-pipe water draining system. The compound is characterized by comprising the following raw materials in parts by weight: 90-100 parts of polyvinyl chloride resin body, 0.3-0.5 part of an antioxidant, 50-60 parts of a fire retardant, 0.5-2 parts of an antistatic agent, 2-3 parts of an impactresisting agent, and 0.5-1 part of a mould inhibitor. According to the composition, additives are added to polyvinyl chloride to improve polyvinyl chloride; polyvinyl chloride with specific content ismixed with other components to prepare the composition, and the water draining pipeline manufactured through the composition is high in impact resistance, so that the 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 drainage pipes in drainage systems. Background technique [0002] At present, the drainage pipes in the drainage system used in buildings are mainly PVC pipes, and the PVC pipes are mainly polyvinyl chloride, but polyvinyl chloride has problems such as easy decomposition and poor impact resistance, so it is necessary to add various additives to polyvinyl chloride. Improve the performance of polyvinyl chloride, so that it can obtain more excellent performance, adapt to more severe application environment, and improve its impact resistance. [0003] However, the current drainage pipes made of polyvinyl chloride added with various additives have insufficient impact strength and short service life. Therefore be badly in need of inventing and manufacturing a kind of new composition, thereby the drainpipe that this composition is made has high im...
