Description

A method of preparing multi-functional TPO composite lether
Technical field
The present invention relates to a kind of methods for preparing multi-functional TPO composite lether, are applied to TPO and produce and process technical field.
Background technique
With the development of society, building trade development is getting faster, the demand of required TPO composite lether is increasing, And nowadays the high-quality TPO of complex building finishing of market production etc. is by special working process, so that TPO has There is better performance, meets the quality material that can nowadays cope with mal-condition.It is most of to be in the modification for carrying out TPO Using the method that inorganic filler is added, and the addition of inorganic filler will lead to the reunion of inorganic powder in process, to production Processing brings many troubles.Therefore the organic coating for carrying out inorganic particulate, may be implemented the surface organic of inorganic particulate, from And improve itself and the interface compatibility of organic matter and the dispersibility in organic matter.Solves the group of inorganic particulate in processing reaction Poly- problem is a kind of method by electrodeless dusty material in conjunction with TPO composite material well.
Summary of the invention
The present invention solves the technical problem of: in view of the deficiencies of the prior art, provide a kind of preparation of TPO composite lether The method of method, the direct doping inorganic powder object of abandoning tradition realizes inorganic grain using the organic coating of inorganic powder particle The surface organic of son, solves the inhomogeneities of reunion and the doping of inorganic powder object.
In order to solve the technical problem, one technical scheme adopted by the invention is that: a kind of nothing preparing TPO composite material is provided The organic coating method of machine powder particle, realizes the surface organic of inorganic particulate, to improve its interface phase with organic matter Capacitive and the dispersibility in organic matter.
The present invention also provides a kind of methods for preparing multi-functional TPO composite lether, include the following steps:
(1) 30-50% pure water is added in polymeric kettle, acidic materials are added, temperature is controlled at 0-5 DEG C；
(2) stirring of polymeric kettle high speed is added in a certain amount of aniline (being evaporated under reduced pressure twice), certain density mistake is added dropwise Ammonium sulfate (APS), hydrochloric acid solution, inorganic material powders, dispersing agent, the PH for controlling solution is 2.5-4.5, continues to stir 1h；
(3) the above solution is added in the mixed solution for filling a certain amount of aniline, hydrochloric acid, the reaction was continued 2h；(4) successively With dilute hydrochloric acid, dehydrated alcohol, deionized water washing is filtered, until when BaCl2 solution is added in filtrate without white precipitate, OP-10 is added dropwise into the solution made quickly to stir, obtains the Polyaniline emulsion of load organic/inorganic substance powder；
(5) Polyaniline emulsion of inorganic powder is filtered resulting load, it is dry；
(6) single screw extrusion machine is added in the product after drying TPO composite material, maleic anhydride, step (5), through molten Melt hybrid reaction extrusion, TPO film sheet is made in press polish, cooling, curling；
In above-mentioned steps,
Acidic materials are hydrochloric acid solution, concentration 1mol/L；
The molar ratio of aniline and ammonium persulfate is 1:2；
Electrodeless powder object have calcite, kaolin, wollastonite, talcum, mica, rutile, sericite, pyrophillite, mica, Montmorillonite, shepardite, quartzy calcite, chalk, zeolite, illite, montmorillonite, diatomite, graphite, shepardite, the tremolite, thoroughly The one or several kinds of lime stone, asbestos, quartz；
Dispersing agent is the one or several kinds of white oil, paraffin, low molecular weight polyethylene；
The particle size of inorganic powder object is 50-400 mesh.
Beneficial benefit of the invention is: by the method to TPO material composite inorganic compound filler, improving tradition The performance of TPO composite material improves the performance of TPO by adding different inorganic powder objects, reaches required practicability Can, while reducing the cost of TPO raw materials for production.With the difference of traditional polymer-doped electrodeless powder, the present invention is using inorganic The organic coating of powder particle, realizes the surface organic of inorganic particulate, thus improve its interface compatibility with organic matter and Dispersibility in organic matter.So, the performance of upper product being improved largely is being produced, is meeting reality A demand to various environment in.
