Embodiment Construction

[0007] Below in conjunction with the specific implementation mode for further description:

[0008] The method for preparing nanoplastics by intercalation compounding is characterized in that: firstly, a monomer or a polymer is inserted between layered silicates (such as montmorillonite) treated with an intercalation agent to destroy the tight order of the layered silicates The stacking structure makes it peel off into layered basic units with a thickness of about 1nm and a length and width of 30-100nm, which are evenly dispersed in the polymer matrix, realizing the nanoscale Composite on. The intercalation composite method can be further divided into intercalation polymerization and polymer intercalation. The intercalation polymerization method is to firstly disperse and intercalate the polymer monomers into the layered silicate sheets, and then polymerize in situ, using a large amount of heat released during polymerization to overcome the force between the silicate sheets a...

Abstract

The invention relates to the technical field of plastics, particular to a nano-plastic intercalation compounding preparation method which is characterized by intercalating monomers or polymers betweenphyllosilicate (such as montmorillonoid) which is treated by an intercalator to destroy close-packed structure of phyllosilicate and peel the phyllosilicate into sheet units with thickness about 1 nmand length and width ranging from 30 nm to 100 nm, dispersing the sheet units uniformly into a polymer matrix, thereby realizing compounding of high-molecular polymer and the sheets of phyllosilicatein nano scale. The intercalation compounding method includes an intercalation polymerization method and a polymer intercalation method. The intercalation polymerization method includes dispersing monomers, intercalating into sheets of phyllosilicate, performing in-situ polymerization to generate great heat to overcome acting force among the sheets of phyllosilicate and peels the sheets, thereby achieving nano-scale compounding between the sheets of phyllosilicate and a plastic matrix. The polymer Intercalation method includes mixing a polymer melt or solution with phyllosilicate, peeling phyllosilicate into sheets in nano scale by chemical and thermodynamic actions while dispersing the sheets into a polymer matrix. The nano-plastic intercalation compounding preparation method has the advantage that inorganic nano materials can be dispersed into the plastic matrix resin uniformly and easily in nano scale.
