Hard polyvinyl chloride low-foaming building pipe material formula

Abstract

The invention discloses a rigid polyvinyl chloride low-foaming building pipe formula, which comprises 56-65g of polyvinyl chloride resin, 4-10g of MBS impact modifier, 2-7g of lead salt stabilizer, AC Foaming agent 0.3-1g, stearic acid 0.1-1g, calcium carbonate 0.5-6g. The rigid polyvinyl chloride low-foaming construction pipe material of the present invention has reasonable design of mixing ratio, low cost, high strength, strong moisture-proof, weather-proof and heat-insulating capabilities.

Description

technical field [0001] The invention belongs to the technical field of building materials and pipes, in particular to a formula for rigid polyvinyl chloride low-foaming construction pipes. Background technique [0002] Pipes are necessary materials for construction projects. Commonly used are water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. With the development of science and technology, the pipes used in home decoration have also experienced the development process of ordinary cast iron pipe → cement pipe → (reinforced concrete pipe, asbestos cement pipe) → ductile iron pipe, galvanized steel pipe → plastic pipe and aluminum-plastic composite pipe . The existing rigid polyvinyl chloride low-foaming construction pipes have unreasonable formulations, cannot be adapted to the needs of existing production and life, have high cost, poor strength, and poor moisture-proof, weather-proof, and heat-insulating capabilities.
