Structural sheet, and making method and application thereof

Abstract

The invention belongs to the technical field of the material science, and discloses a structural sheet, and a making method and an application thereof. The structural sheet is made by using the following components, by weight, 100 parts of a thermoplastic resin matrix, 5-10 parts of an impact resistant modifier, 3-5 parts of a compatilizer, 0.6-1.2 parts of an antioxidant and 40-60 parts of a glass fiber. The making method comprises the following steps: sequentially adding the above components into a high-speed mixer according to the above weight parts, uniformly mixing the components in the high-speed mixer, discharging the obtained mixture, and sealing; and adding the mixture into an extruder, carrying out melt blending extrusion, and carrying out hot pressing and cold pressing in a block press to make the structural sheet. The structural sheet can be used in a transport compartment body. The structural sheet has the characteristics of light weight, high strength, excellent impact resistance, and reduction of the vibration of explosion waves.

Description

technical field

[0001] The invention belongs to the technical field of material science and relates to a structural board, a preparation method and an application thereof. Background technique

[0002] When loading and transporting explosives (such as fireworks and firecrackers, explosive equipment, dangerous goods and other chemical materials and low-flammability materials), shocks should be prevented to prevent explosions of inflammable and explosive materials. However, in the current situation, most of the boxes used for reprinting flammable and explosive materials are ordinary boxes, mostly metal boxes. In the process, there are great risks.

[0003] Chinese patent CN102181096A discloses a glass fiber reinforced polypropylene material and its preparation method, which is prepared by blending polypropylene, compatibilizer, glass fiber, antioxidant, light stabilizer and lubricant, extruding strands and cutting into pellets Obtained, wherein the compatibilizer is maleic a...
