Description
Technical field
The invention belongs to prepare the field of TPO composite lether, and in particular to a kind of side of the modified TPO composite lether of inorganic oxide
Method.
Background technique
With the raising of the development of society and people's life, indoor environment receives more and more attention, currently used for
Indoor partition, crown wall outer layer finishing be mostly coating, paint etc., it is right wherein containing a large amount of formaldehyde and other carcinogens
Resident's health causes significant damage.TPO material has heat preservation, heat-insulated etc. as a kind of green, economic, environmental protection material
Feature has been widely used in construction and decoration field, especially indoors partition wall, crown wall surface layer fit up field, and magnetic
Property TPO thin-film material due to itself having magnetism, it is only necessary to there is wall magnetism can fix magnetic TPO film, can be with
Meaning replacement, construction period short have received extensive concern.In recent years, polymer/inorganic nanometer particle compesite becomes research
Hot spot.But also due to inorganic nano-particle partial size is small (1-100nm), surface can be big, is in thermodynamics non-steady state, easily rolls into a ball
It is poly-, it is not easy to disperse in a polymer matrix, it is caused to lose the characteristic of nanoparticle.In addition, organic and inorganic component is in warm
It is incompatible on mechanics that be also unfavorable for nanoparticle evenly dispersed in the polymer.Present invention uses the inorganic molten of excellent in stability
Glue, overcomes in traditional Preparing Organic-inorganic Nano Hybrid Material preparation process that inorganic component is easy to reunite, disperses in the polymer
Property difference disadvantage.Multi-layer co-extruded method is used simultaneously, and simple process saves the energy, high production efficiency, which can make
For the windows energy-saving material such as automobile, aircraft, building.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of preparation method of Preparing Organic-inorganic Nano Hybrid Material,
It is prepared into the modified TPO composite lether of inorganic oxide with the processing of TPO substrate again, this method uses mixed nanometer inorganic oxide
Object colloidal sol is as inorganic phase, and polymethyl methacrylate is as organic phase.Surface is carried out to nano-doped tin oxide sol first
It is modified, unsaturated double-bond is introduced as surface aggregate grafting active site in surface of inorganic particles, then will be inorganic by solvent displacement
Nanoparticle is dissolved in methyl methacrylate monomer, by obtaining polymer/inorganic composite material after in-situ polymerization.It again will be upper
Preparing Organic-inorganic Nano Hybrid Material is obtained with the same die head of cystosepiment of TPO substrate, TPO substrate lower surface after stating heat cure
Melting extrusion is synthesized through conventional three-roll press-polishing, cooling, traction, winding to get to the modified TPO of inorganic oxide continuously prepared
Leather.The invention advantage is that inorganic nano-particle is initially in dissolved colloidal state, good dispersion, after surface treatment more significantly
Reduce a possibility that reuniting between particle.Therefore, can be good at being dispersed in methyl methacrylate in solvent replacement process
In monomer, this makes inorganic nano-particle good dispersion in a polymer matrix, and composite property is excellent, there is good power
And optical property, while TPO composite lether is prepared by way of coextrusion, it does not need to be prepared by binder
At multilayered structure, manufacture craft is simple.A kind of present invention technical solution used for the above purpose are as follows: polymer/nothing
