Description
Technical field
The present invention relates to a kind of preparation methods of organic amine modified montmorillonoid/polyamide nano-composite.
Background technology
Polyamide is that kind earlier is developed in engineering plastics, has many excellent performances such as high-strength, oil resistant, damping,
It is widely used in fields such as automobile, electrical equipment, mechanical part, transportation equipment, weavings.With automotive small,
The quickening of electronic electric equipment high performance, mechanical equipment lightweight process proposes higher requirement to the performance of polyamide,
Especially as structural material, need further to improve its intensity, heat resistance and cold resistance etc..
Many inorganic material, such as glass fibre, talcum, calcium carbonate, clay can serve as filler or reinforcing agent to carry
The performance of high high molecular material.The raising degree of the performance of high molecular material generally depends on the loading of filler, filler in base
Dispersion degree and the degree of orientation, filler/base body interface situation in body etc. (Macromolecules, 2011,44:3856-3861.).
In recent years, with the development of nanometer technology, polymer nanocomposites are prepared using Nano filling, are had improving material
There is unique advantage, and cause the more and more interest of researcher in terms of performance and imparting material new capability.As Japan is rich
It is compound that the scientific research personnel of field research institute, U.S. Connell and Michigan university etc. prepares polymer/montmorillnoite nano to intercalation
Material has made extensive research, wherein just including having synthesized 6/ Nano composite material of montmorillonite of nylon.Chinese Academy of Sciences's chemistry is ground
Study carefully QiZongNeng professor et al. the nano composite polymer-montmorillonoid material that takes the lead in having carried out at home research, obtained more
Item achievement has simultaneously applied for patent (CN1162470C, CN1137198C), as monomer intercalation condensation methods prepare nylon/montmorillonoid nanometer
Composite material etc. (CN 1055706C, CN 1081207C).Research has shown that, compared with pure PA6, nanometer enhancing particle can be significantly
Improve the mechanical property of PA6.Therefore, polyamide is modified using nano-particle, for improving the overall performance of material, opened up
The application range of exhibition material is of great significance.
Montmorillonite is a kind of silicate of stratiform, has many advantages, such as that raw material is easy to get, is cheap, can directly by monomer or be gathered
The piece interlayer that object is inserted into montmorillonite is closed, it is nano unit to be removed the montmorillonite of stratiform using heat of polymerization or strong shearing force,
It is evenly dispersed in polymeric matrix.The nano combined materials of montmorillonite/PA6 prepared by in-situ inserted method and melt intercalated method
Material the experiment proved that, since montmorillonite is homogeneously dispersed in nanoscale in PA6 matrixes so that the mechanical property of composite material
Be improved (petrochemical industry, 2006,35 (8):778-781)；Particularly pass through the montmorillonite of organic-treating, interlamellar spacing
Expanding makes monomer or polymer be easier the expansion and stripping of piece interlayer, the further lamella of promotion montmorillonite into montmorillonite
From so that its mechanical property (tensile strength, impact strength etc.), hot property, flame retardant property all obtain different degrees of raising.
In above-mentioned preparation process, in order to enable nanometer enhancing particle and polyamide are compound, decentralized medium etc. can be often used
Nanometer enhancing particle is pre-dispersed using the progress such as high-shear emulsifying equipment, ultrasonic equipment.Preparation process needs to add other
Equipment, process are complex (CN1127534C, CN1148398C).
The present invention is directly added organic by one-step method in-situ polymerization during prepared by monomer of polyamide in-situ polymerization
Amine modified montmorillonoid without carrying out the processes such as pre-dispersed, that is, enhances the performance of polyamide material, and reduce apparatus and process mistake
Journey reduces production cost.
