Description
Technical field
The present invention relates to the preparation field of laminated film, be specifically related to the preparation method of a kind of Graphene-poly (propylene carbonate) Green Composites.
Background technology
Graphene oxide is the Graphene of functionalization, molecular structure is as the criterion two-dimensional layer, containing many functional groups such as hydroxyl, carboxyl, carbonyl and epoxy group(ing), there is very high specific surface energy and good wetting ability and mechanical property, and it is better dispersed in polar solvent, this new type functional nano material receives the concern of more and more scientist, has become the focus of scholars's research.Graphene oxide is not only the starting point of extensive synthesizing graphite alkene, also one of the most effective approach realizing graphene functionalized is become, by being prepared as new type functional improving agent by graphene oxide or optimizing various matrix material, become a kind of important channel of composite modification.
Petroleum base synthesized polymer material, since appearance, with low price, specious, stable in properties, easy to process and be widely used in a lot of occasion, and has become the indispensable basic material of people's lives, social development and articles for use gradually.But synthesized polymer material is non-renewable petroleum chemicals; the simultaneously refractory organics that has of portion of material; analyze from environment protection, a large amount of discarded plastics bring the puzzlement of white pollution to the physical environment of human survival, this increases the pressure of environment undoubtedly to a certain extent.And degradable macromolecular material is inexhaustible renewable resources, can not produces environment and pollute.
Poly (propylene carbonate) is with the environmental protection shaped material of propylene oxide and carbonic acid gas a kind of Wholly-degradable that is Material synthesis, be considered to one of current most promising environmentally-friendly plastic, but this material glass transition temperature is lower, solvent resistance, barrier, thermostability and mechanical endurance are poor.
Summary of the invention
For above-mentioned technical deficiency, the invention provides the preparation method of a kind of Graphene-poly (propylene carbonate) Green Composites, laminated film prepared by the method have that poly (propylene carbonate) possesses excellent degradable quality, but also possess good solvent resistance, barrier, thermostability and mechanical endurance.
The present invention solves the problems of the technologies described above the technical scheme taked: the preparation method of a kind of Graphene-poly (propylene carbonate) Green Composites, comprises the following steps:
(1) graphenic surface pre-treatment;
(2) pretreated Graphene and poly (propylene carbonate) and the process of polyvinyl alcohol high-speed mixing;
(3) extrude and vacuumize granulation.
The described graphenic surface pretreatment process of above-mentioned steps (1):
A. Graphene and the process of Sodium dodecylbenzene sulfonate high-speed mixing;
B. the Graphene mixture after process and silane coupling agent KH560 high-speed mixing are carried out secondary surface preparation.
Extruding the treatment condition vacuumizing granulation described in above-mentioned steps (3) is: be fed into by the raw material mixed in the twin screw extruder of preset temp 130 ~ 170 DEG C, screw speed 150 ~ 250r/min to vacuumize and extrude pelletizing.
The weight part ratio of above-mentioned Graphene, poly (propylene carbonate) and polyvinyl alcohol is 1 ~ 6:60 ~ 90:70 ~ 80.
The polymerization degree of above-mentioned polyvinyl alcohol is 600 ~ 2000.
Compared with prior art, matrix material prepared by the preparation method of a kind of Graphene-poly (propylene carbonate) Green Composites of the present invention possesses excellent biodegradable performance, the interpolation of modified graphene and polyvinyl alcohol, to poly (propylene carbonate) synergistic function, make matrix material possess good solvent resistance, barrier, thermostability and mechanical endurance.Preparation method's technique of the present invention is simple, easy handling, and very suitability for industrialized is produced.
