Abstract

The invention discloses a novel high-thermoplasticity PP super-thick plate and a processing method, and belongs to the technical field of novel processing and application of high polymer materials. The super-thick plate comprises a carbon fiber reinforced epoxy resin composite material upper skin, a carbon fiber reinforced epoxy resin composite material lower skin, a PP honeycomb plate, a group ofepoxy resin foam, a group of epoxy resin foam reinforced supports, an upper epoxy resin adhesive film and a lower epoxy resin adhesive film. According to the novel high-thermoplasticity PP super-thick plate, through the arrangement of the multi-layer laminated structure, the super-thick plate has scratch resistance, a modified plate layer further has high impact resistance, the physical characteristics of the plate can be greatly improved, and the universality of the plate is enhanced. The processing method of the novel high-thermoplasticity PP super-thick plate is simple in process and rapidin forming, improves the production efficiency, and reduces the production cost, so that industrial application in the industrial field is met.

Description

technical field [0001] The invention belongs to the technical field of novel processing and application of polymer materials, and in particular relates to a novel high thermoplastic PP ultra-thick plate. The invention also relates to a processing method of a novel high thermoplastic PP ultra-thick plate. Background technique [0002] Polypropylene plastic board (referred to as PP board), PP board is a semi-crystalline material. It is harder and has a higher melting point than PE. Usually, PP is modified by adding glass fibers, metal additives or thermoplastic rubber. However, the following technical problems exist in the prior art: low strength, poor flame retardancy, and easy oxidation. [0003] Honeycomb panels are formed through the improvement of PP panels. Honeycomb panels, also known as sandwich panels, are obtained by adding a honeycomb interlayer between two layers of panels. They have the characteristics of light weight and high strength. High strength, water re...
