As preferably, described antioxidant refers to that thio-2 acid tristearin alcohol ester, double octadecyl tetramethylolmethane are double sub-
One or more in phosphate ester, four [β-(3,5-di-tert-butyl-hydroxy phenyl) propanoic acid] pentaerythritol ester.
As preferably, described compatilizer is polypropylene grafted acrylic acid.
The present invention provide one modified micaceous/composite plastic of polypropylene, it is characterised in that described is modified micaceous, presses
According to following steps, it is modified:
(1) Muscovitum pretreatment: Muscovitum is placed in 150 DEG C of thermostatic drying chambers be dried 20h, put into exsiccator is carried out cold
But, appropriate Muscovitum and ethanol being added in the beaker of band magneton, limit dropping oxalic acid limit stirring, control ph is 3, ultrasonic
0.5h, is then dried 15h in 70 DEG C of thermostatic drying chambers, i.e. can get the Muscovitum of pretreatment；
(2) silane coupler pretreatment: measure the distilled water of 500ml in the beaker of band magneton, weigh quantitative
KH550, KH550 are 1:9 with the mass ratio of distilled water, and dropping limit, limit is stirred, and controlling solution ph is 3, after hydrolyzing 1h under room temperature
Obtain KH550 aqueous solution；
(3) modified micaceous preparation: weigh the Muscovitum in appropriate step (1) in the there-necked flask of band magneton, Jiang Sankou
Flask is placed in the thermostat water bath of 80 DEG C, and under rotating speed is 600r/min, drip in a certain amount of step (2) is silane coupled
Agent, reacts 1h, adds appropriate paraffin, reacts 1h, and reaction end is placed in 70 DEG C of thermostatic drying chambers, i.e. available modified cloud
Female.
The invention has the beneficial effects as follows: the present invention, by using modified Muscovitum, effectively improves itself and high polymer
The compatibility and dispersed performance, and then make the modified micaceous/composite plastic of polypropylene prepared not only have acid and alkali-resistance, resist
Advantages such as ultraviolet, and make product have excellent stability and thermostability, additionally, composite plastic in terms of activeness and quietness also
There is a certain degree of raising.
