Abstract

The invention discloses a flame retardant foaming material with low water absorption. The flame retardant foaming material is characterized by comprising the following substances in parts by weight: 3.5-4.9 parts of nano calcium carbonate, 12-25 parts of synthetic plant ester, 10-15 parts of glass beads, 5.5-6.4 parts of ground calcium carbonate, 5-13 parts of brominated epoxy resin, 26-47 parts of expanded graphite, 3-11 parts of butyl octade, 11-24 parts of dicyclopentadienyl iron, 21-35 parts of butyl stearate, 45-64 parts of acrylonitrile-butadiene-styrene copolymer and 25-40 parts of oleic acid. According to the invention, the foaming material has excellent flame retardant effect and also keeps the advantages such as thermal insulation, light weight and low water absorption.

Description

technical field [0001] The invention relates to a flame-retardant foaming material with low water absorption. Background technique [0002] Foaming materials are widely used, because of their high strength, light weight, excellent thermal insulation performance and high energy absorption capacity, they can be used as packaging for various instruments, valuables, precision instruments, vegetables, fruits and aquatic products, etc. Because of its low thermal conductivity, low water absorption, good electrical insulation, sound insulation, moisture resistance, and simple molding process, it is widely used in roadbed laying of roads and bridges, housing construction, fishing and refrigeration industries. Insulation materials etc. Among them, as an excellent building material, expanded polystyrene resin is mainly used for roofs and walls of buildings. It has a very good energy-saving effect as an external thermal insulation composite wall; it is suitable for residential building...
