Flame-retardant and anti-aging foam material

Abstract

The invention discloses a flame-retardant and anti-aging foam material which comprises the following ingredients in parts by weight: 35-41 parts of polybutylene terephthalate, 35-62 parts of isotatic polypropylene, 9-20 parts of epoxy bran butyl oleate, 10-15 parts of nickel oxide, 5-12 parts of buna, 15-30 parts of phenolic resin, 25-37 parts of acrylonitrile-butadiene-styrene copolymer, 19-30 parts of N-phenyl-alpha-aniline, 15-23 parts of an aluminate coupling agent and 40-49 parts of microcrystalline wax. The foam material has a good flame-retardant effect and a good mechanical property and is small in density and light in weight, and the anti-aging performance can be improved as an antioxidant is added. The foam material has the advantages of heat preservation, heat insulation and low water absorption.

Description

technical field [0001] The invention relates to a flame-retardant and anti-aging foam material. Background technique [0002] Isotactic polypropylene is polypropylene with an isotactic structure. It is a highly crystalline thermoplastic resin with excellent rigidity and high temperature impact resistance. [0003] Polypropylene (PP) foamed plastic products have good thermal stability (maximum service temperature up to 130°C) and good product dimensional stability at high temperatures, high toughness, tensile strength and impact strength, and excellent microwave adaptability It has attracted much attention due to its safety and environmental friendliness, thus becoming a good substitute for polystyrene (PS) foam plastics and polyurethane (PU) foam plastics. At present, polypropylene foam products are widely used in the field of food and food packaging, such as: trays, dishes, boxes, basins, beverage cups, sealed boxes and sealing gaskets for drinking water bottles, meat pack...
