Abstract

The invention discloses a composite modified polyphenylene sulfide material for a water supply pipe insert and a preparation method thereof. The material comprises the following ingredients: 100 weight parts of PPS containing 40% of glass fiber, 10-50 weight parts of CaCO3 / MBS / UV-531copolymer mixture, 3-5 weight parts of solubiliser, 0.5-1 weight parts of carbon black color masterbatch, and 0.0002-0.0005 weight parts of white oil. The preparation method comprises the following steps: drying a blend of PPS containing 40% of glass fiber, CaCO3 / MBS / UV-531copolymer mixture, carbon black color masterbatch, and white oil in a mixing drier, then putting the dried blend into an injection machine for injection molding to prepare the composite modified polyphenylene sulfide material for the water supply pipe insert. The prepared material of the invention has comprehensive performance and excellent quality, and can be applied in wide range of areas.

Description

technical field

[0001] The invention relates to the technical field of composite modified plastics, in particular to a composite modified polyphenylene sulfide material used as an embedded part of a water supply pipe fitting and a preparation method thereof. Background technique

[0002] In the prior art, the inner parts of the water supply pipe fittings (see GB / T18742.3-2002 for details) embedded in the polypropylene pipe fittings used to transmit hot and cold domestic water are usually made of brass pipe fittings that are machined and then plated with chrome or nickel. Prepared. However, brass water supply pipe inserts have the following disadvantages when used in domestic water supply pipes for hot and cold domestic water:

[0003] 1. Since the outer surface of the inner part of the brass water supply pipe fitting is plated with chrome or nickel, this is not conducive to the control of the content of heavy metal chromium or nickel in drinking water. Long-term drinking of...
