Abstract

The invention discloses a PP (Propene Polymer) honeycomb board material for an automobile spare tyre cover plate. The PP honeycomb board material for the automobile spare tyre cover plate comprises asurface layer, a bottom layer, a polypropylene honeycomb core layer arranged between the surface layer and the bottom layer, and a hot melt adhesive membrane layer for bonding the surface layer, the polypropylene honeycomb core layer and the bottom layer into a whole. The hot melt adhesive membrane layer is prepared from the raw materials: ethylene-vinyl acetate copolymer, 1,2-benzothiazoline-3-ketone, a butyl rubber, polymaleic anhydride, 2,6-butylated hydroxytoluene, a filler and the like; The hot melt adhesive membrane with a good bonding property, high bonding strength, high stripping strength, high heat resistance and cohesion strength, high stability, fast drying speed, less consumption, high heat stability, and excellent heat resistance and high-and-low temperature resistance is combined with a structure of a honeycomb board, so that the bonding strength of the honeycomb board is improved, a mechanical performance of the PP honeycomb board is further improved, the service life of the PP honeycomb board is prolonged, the emission of VOC (Volatile Organic Compounds) in an automobile is effectively reduced, and meanwhile, the PP honeycomb board material for the automobile sparetyre cover plate has better weight reduction and sound insulation effects, is waterproof and wetproof, and has a better corrosion resistance effect.

Description

technical field [0001] The invention relates to a honeycomb panel, in particular to a PP honeycomb panel material for an automobile spare tire cover. Background technique [0002] The special structure of the honeycomb panel is derived from bionics and inspired by the structure of bee nests in nature, so human beings creatively invented the panel with honeycomb sandwich structure. Corresponding to different material selection, it is applied in different fields. Metal honeycomb panels have been studied more at home and abroad. Because this type of material has light weight, high specific strength and specific stiffness, and has excellent electrical insulation, electromagnetic wave permeability, sound insulation, and heat insulation, it is mainly used in Aerospace, shipbuilding, construction industry and other fields. With the rapid development of the automobile industry, based on the lightweight design of automobiles, most of the interior and exterior accessories of automob...
