Abstract
The invention discloses a nanoparticle composite material, which is composed of, by weight: 30-40% of plastics, 40-50% of natural fiber, 5% of inorganic nanoparticles, 5% of SiC nano-powder and 10% of various additives. The components are subjected to high speed mixing, extrusion, injection molding and mould pressing and other processes so as to obtain a finished product. According to the invention, the composite material with high strength and toughness can be prepared, the application range of the composite material is expanded, and also, waste plastics and crop waste can be used, thus saving natural resources and reducing pollution.
Description
Technical field
The present invention relates to a kind of polymer composite, particularly a kind of nano composition.
Background technology
Along with the high speed development of Chinese national economy and the raising of living standards of the people, people increase day by day to the demand of timber, and natural forest development speed does not catch up with the demand of market to timber far away, in order to alleviate the disparities between supply and demand of timber, many plastics and Wood-plastic material have appearred in various places in succession, in order to replace timber, manufacture various products, but plastics are aging fast, degraded is difficult, waste or used plastics is difficult to process, so that become the source of pollution contaminate environment; The toughness of prior art Wood-plastic material is lower, has limited its popularization and use.Adopt traditional method for toughening, as rubber toughened, can make material stiffness, strength decreased; And adopting filler to strengthen, toughness can descend again.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose the nano composition that a kind of intensity and toughness are higher, enlarge the range of application of matrix material.
The present invention is achieved through the following technical solutions technical object.
