Abstract

The invention discloses a high-strength impact-resistant thermoplastic environment-friendly plastic, and particularly relates to the technical field of thermoplastic plastics; the high-strength impact-resistant thermoplastic environment-friendly plastic comprises the following raw materials: thermoplastic plastics, modified carbon fibers, nanoparticles, a plasticizer, a coupling agent, an antioxidant and a lubricant. The carbon fiber is modified by nitric acid and hydrogen peroxide, wherein thermoplastic plastic in a molten state enters the grain holes of the modified carbon fiber under high pressure in the compounding process, so that a glue nail effect is generated, a mosaic structure and a reticular structure form are formed, and the combination between the modified carbon fiber and the thermoplastic plastic can be effectively improved; therefore, the physical and mechanical properties of the thermoplastic plastic are effectively improved. By adding the nano particles, the nano particles can interact with the modified carbon fibers to improve the strength of the thermoplastic plastic, and the nano particles can repair holes in the surface of the thermoplastic plastic after the modified carbon fibers and the thermoplastic plastic are compounded, so that the strength and impact resistance of the thermoplastic plastic are better.

Description

technical field [0001] The invention relates to the technical field of thermoplastics, more specifically, the invention relates to a high-strength impact-resistant thermoplastic environment-friendly plastic and a preparation method thereof. Background technique [0002] Thermoplastics are the most widely used plastics. They are formulated with thermoplastic resin as the main component and various additives. Under certain temperature conditions, plastics can soften or melt into any shape, and the shape remains unchanged after cooling; this state can be repeated many times and always has plasticity, and this repetition is only a physical change. The types of thermoplastics mainly include Polyethylene, polypropylene, polyvinyl chloride, polystyrene, etc. However, these products are all based on non-renewable resource petroleum, which consumes a lot of energy in the production process and has a serious impact on the environment. Thermoplastics can be divided into general-purpo...
