Foam material plate for automobile

Abstract

The invention discloses a foaming material plate for an automobile, and belongs to the technical field of automobiles. The foaming material plate for the automobile comprises a foaming plate, the foaming plate comprises a base plate, a honeycomb plate layer is arranged in the base plate, the upper surface of the base plate is coated with an adhesive layer A, and the lower surface of the base plateis coated with an adhesive layer B; an assembling groove is formed in the left side of the foaming plate, and an assembling block is fixedly connected to the right side of the foaming plate. The honeycomb plate layer is additionally arranged in the base plate, the honeycomb plate layer is integrally of a honeycomb structure, the honeycomb structure layer can continuously weaken sound transmittedfrom the outside, and therefore the sound insulation and noise reduction effects are achieved, the sound insulation paper A and the sound insulation paper B are bonded to the two faces of the base plate correspondingly, and the overall sound insulation effect of the foaming plate is further improved; and the foam material plate is suitable for wide popularization and application.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a foam material plate used for automobiles. Background technique [0002] PVC foam board is also called Chevron board and Andy board, its chemical composition is polyvinyl chloride, so it is also called foamed polyvinyl chloride board. Widely used in passenger cars, train car ceilings, box core layers, interior decoration panels, building exterior wall panels, interior decoration panels, offices, residences, public building compartments, commercial decorative frames, and clean room panels , Ceiling boards, screen printing, computer lettering, advertising signs, display boards, sign boards, album boards, etc. [0003] Patent No. CN206016128U discloses that a foamed board is a double-layer structure formed at one time, the upper layer is a PVC non-foaming layer, and the lower floor is a PVC foaming layer; the layer of the PVC foaming layer in contact with the PVC non-foaming l...

AI Technical Summary

Problems solved by technology

[0004] At present, there are certain deficiencies in the technology of automobile foam boards: 1. Although traditional automobile foam boards have certain sound insulation properties, the sound insulation effect is not good. When encountering large decibel noises from the outside world, they cannot effectively isolate the noise; 2. 1. It is not convenient to assemble and splice traditional automobile foam boards, and the practicability is not strong
