Description
Technical field
The present invention relates to a kind of plastics insulation modifying agent and preparation method thereof, belong to plastic, thermal-insulation field of material technology.
Background technology
Polypropylene plastics is widely applied to the packaging of all trades and professions due to its excellent mechanical property and cheap price
And use, applied as tubing PP-R by extremely wide in each building trade, but be used as tubing due to polypropylene itself
Characteristic, its heat-insulating property is unsatisfactory to be used as insulation material use.If the insulation of polypropylene material can be improved
Performance, it will lift polyacrylic use value to a greater extent.Existing insulation material such as application number 201511015638.3
Chinese patent disclose a kind of nanometer heat insulating material and preparation method thereof, the insulation material is added based on binary aerogel
The substep compacting of the materials such as perlite and tiny balloon has been added to form.This kind of insulation material thermal conductivity factor is low, high insulating effect, still
This insulation material can not be processed into tubing and higher in Costco Wholesale because mechanical property is restricted, and can not carry out big
The marketing of scale.
The content of the invention
It is an object of the invention to provide a kind of plastics insulation modifying agent and preparation method thereof, a kind of plastics are changed with insulation
Property agent and preparation method thereof can effectively solve the technical problem of existing polypropylene plastics heat insulation effect difference.
The technical solution adopted in the present invention is：It is made up of following masses component material：It is acidified perlite：76.1-
87.7 parts, coupling agent kh-570：3.2-5.8 parts, azodiisobutyronitrile 0.35-0.5 parts, neopelex 1.2-1.7
Part, acrylonitrile 11.6-14.7 parts, deionized water 3.5-5.6 parts.
It is described acidifying perlite specific preparation method be：Expanded perlite is dipped to 2-3 in the dilute sulfuric acid at 95 DEG C
Filtration washing after hour, carries out ultrasound, the perlite being acidified again after obtaining filtration cakes torrefaction.
Plastics with insulation modifying agent preparation method be：
Acidifying expanded perlite is added to heating stirring in toluene, Silane coupling reagent KH-570 insulation is added after being warming up to 65 DEG C
Heating is filtered and with absolute ethyl alcohol washed product and is dried to obtain coupling agent modified expanded perlite while hot after 8 ~ 10 hours.
Coupling agent modified expanded perlite after treatment is put into absolute ethyl alcohol carry out supersound process 10min ~
It is put into after 15min in reaction vessel and adds dispersant neopelex progress heating stirring, when temperature rises to 50 DEG C
It is put into initiator azodiisobutyronitrile initiation and is aggregated in addition deionized water and acrylonitrile monemer when temperature rises to 65 DEG C, insulation is instead
Filtered while hot after answering 7 ~ 8 hours, be washed with deionized and be dried to obtain plastic, thermal-insulation modifying agent.
The beneficial effects of the invention are as follows：Pure expanded perlite is a kind of inorganic mixture, and main component is silica, though
So used in construction material often as insulation material, but nobody uses it for being incubated modified polypropene at present, this is main
Because impurity is more in perlite and can cause the mechanical property of material as the blending of the organic resin such as inorganic material and polypropylene
It is decreased obviously.Perlite is carried out acid treatment, the removal wherein impurity such as metal oxide is simultaneously by the present invention first in preparation process
It is convenient in the building-up process of insulation modifying agent using hydroxycarboxyl group isoreactivity group in the strong oxidizing property increase perlite of sulfuric acid
Bridge formation Silane coupling reagent KH-570 is so as to strengthening perlite and polyacrylic compatibility in grafting on acrylonitrile grafting.The present invention
Plastics the minimum reachable 0.12W/ of the material thermal conductivity obtained in polypropylene is added to insulation modifying agent（m.k）And mechanical property
Can be good, the especially ductility of material is obvious compared with virgin pp material lift.Insulation modifying agent prepared by the present invention is nontoxic, organic
Change degree is high, excellent in stability.The method of the present invention, organic modification is carried out with coupling agent and acrylonitrile to polypropylene, is made
Process the organic solvent such as any discarded object that environment will not be polluted and the toluene used and absolute ethyl alcohol it is recyclable
Recycle.Expanded perlite has cheap advantage and a good heat insulating, and following application prospect is very optimistic.
