Abstract
The invention relates to a preparation method of a polymer-based nanocomposite material, and belongs to the technical field of preparation of inorganic nanocomposite materials. The preparation method comprises the following steps: putting imvite in a reactor, adding organosilane, heating to 80-100 DEG C, melting and mixing for about 60 minutes, so as to enable the organosilane to enter among imvite layers, and breaking materials into pieces to obtain organic imvite; then blending the organic imvite with polymers at a melting state for intercalation so as to obtain a polymer-inorganic nanocomposite material. According to the preparation method, the organosilane is taken as a raw material, so that the organosilane can be inserted among the imvite layers better; the reaction equipment is simple, the cost is low, and the nanocomposite material is easy for large-scale production in factories. The material has good application in the aspects of physics, biology and the like.
Description
Technical field
The present invention relates to a kind of preparation method of polymer base inorganic nano-composite material, belong to inorganic nano composite material technical field
Background technology
Nano composite material is the type material that development in recent years is got up, being called as one of " the most promising material of 21 century ". the concept of nano composite material is to propose for 1984 the earliest, it refers to that dispersed phase size has the matrix material of the one dimension size <100nm of a phase at least. because nano-particles size is little, specific surface area is large, and the quantum effect producing and surface effects, make the more conventional matrix material of nano composite material there is more excellent Physical and mechanical properties, at electricity, magnetic, light, sound, thermodynamics, the aspects such as catalysis and biology present its distinctive performance.Therefore, the preparation of nano composite material has become one of important method obtaining high performance composite, and it is also the basis of nano composite material performance study simultaneously.Application of polymer-inorganic nanocomposite has organic and feature inorganic materials, and by coupling between the two, produces the character of many excellences, has vast potential for future development, is an important channel exploring high performance composite.Adopt ultra-fine inorganic filled polymer material prepared by traditional blend method to be far from reaching nano-dispersed level, only belong to microcosmic matrix material.Reason is: when packing material size size is less than 1～0.1 μ m, particle surface can be very large, and interparticle self aggregation effect is very strong, with existing general blending technology, is difficult to obtain dispersed on nanoscale; On the other hand, the ununiformity of mixing makes existing interface modification technology be difficult to eliminate the interfacial tension between filler and polymeric matrix completely, thus the bonding interface of realizing ideal.Therefore, it is the technological difficulties in this area to improve macromolecular material performance that nano material is scattered in polymkeric substance, is also a focus of Recent study.If inorganic component is wherein stratified material, often adopt graft process to prepare application of polymer-inorganic nanocomposite.Can make like this inorganic phase be dispersed in more uniformly in organic phase, the performance of material obtains larger raising.
Summary of the invention
The object of the invention is to solve existing preparation method's shortcoming, provide that a kind of preparation process is simple, cost is low, need not complex apparatus and the little novel method of environmental pollution.
A kind of preparation method of polymer based nanocomposites, the method refers to laminated inorganic matter to mix with superpolymer, again mixture is heated to molten state, under quiescent conditions or under stirring action, directly intercalation enters people through between organically-modified cheating engaging layer, stratiform polynite salt is peeled off, mutually compound with nanoscale with polymkeric substance, make nano composite material.The process that fusion intercalation is prepared polymer nanocomposites is divided into 2 stages: the one, and the organic-treating of polynite, polynite is placed in to high-speed stirring reactor and adds organosilane agent heating, melting mixing, organosilane agent is entered between cheating engaging layer, material is smashed to the polynite that obtains organising.The 2nd, the melt blending intercalation of organic montmorillonoid and polymkeric substance, obtains polymer based nanocomposites.
Advantage of the present invention and effect are:
1, equipment is simple, adopts double roll mill, single screw extrusion machine, twin screw extruder or injection moulding machine etc. as hybrid process equipment, does not need to drop into special equipment, thereby more efficient, feasible, also has larger industrial prospect simultaneously.
2, monomer-free puzzlement, does not relate to the polymerization of monomer, and the relative molecular mass of polymeric matrix and intensity can not be affected, and do not have the selection problem of monomer and catalyzer yet.
3, do not need to use solvent, adopting the advantage of melt intercalated method is to avoid using solvent, favourable and more economical to environment, and routine techniques is provided, and research is at the ideal system of the restricted polymkeric substance of two-dimensional space.
