Description
Technical field
The invention belongs to technical field of composite materials, more particularly to a kind of degradable composite material and preparation method thereof.
Background technology
Traditional enhancing composite is mainly using glass fibre, carbon fiber etc. as reinforcement, with oil based thermoset
Or thermal plastic high polymer is prepared from as resin matrix, in having been widely used for all trades and professions of national economy.However, I
Also it should be appreciated that because oil is non-renewable resources, its excessive use only can be increasingly exhausted, and with petroleum base high score
The sustainable development of conventional composite materials prepared by son is then a greater impact.Additionally, the production of glass fibre, carbon fiber etc. is no
Great number energy is only expended, and carbon emission amount is huge, and thermosetting resin curing process also discharges a large amount of VOC, threatens workers ' health
And environment, the discarded object of conventional composite materials is not generally degradable or reclaims, and is that ecological environment brings heavy burden.
On the other hand, the total amount of farmland stalk and rubber the like waste just increases with surprising rapidity, and these macromolecules are wiped
It is bright to be difficult to decompose under natural environment, cause serious environmental pollution.For above-mentioned discarded object, traditional processing method is main
It is that soil is buried and burned.Soil is buried can waste substantial amounts of land resource, reduce land resource circulation efficiency, can also to soil, even
Underground water source is polluted；Burning can then produce substantial amounts of carbon dioxide, and other nitrogen, sulphur, the phosphorus that are pernicious to people etc.
Compound, these have encouraged the generation of greenhouse effects and acid rain, particularly atmosphere pollution in recent years, the frequency of such as haze weather
Numerous generation so that traditional incinerating method is restricted.Therefore, how the waste resources such as farmland stalk, rubber to be turned waste into wealth,
And ensure that the composite required performance to be possessed turns into the difficult point of research.
The content of the invention
For drawbacks described above, it is an object of the invention to provide a kind of degradable composite material and preparation method thereof, with stalk
The like waste is main body, and adds various chemical compositions, prepares degradable, function admirable composite, is both saved
Resource, environment is protected, also enrich the species of composite.
