Abstract

The invention provides a foldable PP cellular board, a preparation method of the foldable PP cellular board and a trunk carpet comprising the foldable PP cellular board. The foldable PP cellular boardcomprises a PP cellular board body, a groove is formed in the PP cellular board body, and the end of the groove is located on the edge of the PP cellular board body. The foldable PP cellular board isobtained by placing a PP cellular board substrate in a mold and hot-pressing the PP cellular board substrate into the shape of the foldable PP cellular board. The groove is machined in the PP cellular board through the thermal forming punching technology, so that the PP cellular board is locally weakened, then the folding function is realized, and materials are saved on the premise that the product bearing requirement is met, meanwhile, the whole part is light, and the requirements of car trunk carpet parts for the high bearing performance and folding function are met.

Description

technical field [0001] The invention belongs to the technical field of automotive interior parts, and in particular relates to a foldable PP honeycomb panel, a preparation method thereof and a trunk carpet containing the same. Background technique [0002] Honeycomb panel is a new type of structural material processed from PP (polypropylene) and other materials according to the bionic principle of honeycomb. It has the advantages of light weight, good sound insulation effect, good heat insulation performance, water resistance, and corrosion resistance. Honeycomb panels can be combined with different surface materials, such as carbon fiber panels, wood grain panels, aluminum panels, stainless steel panels, marble panels, rubber panels, blankets, etc., and are used in vehicles, vans, trains, yachts and other transportation tools. Decoration of casings, ceilings, partitions, plywood, floors, etc. [0003] Polypropylene is a non-toxic, odorless, tasteless milky white highly cry...
