Anti-aging insulating foam material

Abstract

The invention discloses an anti-aging insulating foam material which comprises the following substances in parts by weight: 80-95 parts of isotactic polypropylene, 33-45 parts of stearic acid, 1-7 parts of carboxyl methyl cellulose, 3-8 parts of polystyrene, 5-10 parts of organic montmorillonite, 3-7 parts of phosphate, 30-40 parts of phenylcarbinol, 15-19 parts of bits of schefflera arboricola hay, 11-18 parts of cobalt naphthenate, 21-40 parts of oxalic acid and 19-38 parts of sodium butadiene rubber. The foam material disclosed by the invention has an excellent flame retardant effect and further has excellent mechanical properties, and is small in density and light in weight. An antioxidant is added, so that the anti-aging performance can be improved, and the foam material further has the advantages of thermal insulation, heat isolation, low water absorption and the like.

Description

technical field

[0001] The invention relates to an anti-aging thermal insulation 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...
