Description
Technical field
The present invention relates to colloid technology field, in particular to a kind of sour modified polyolefin low temperature quick dissolution method.
Background technique
Lithium ion battery technology is increasingly mature at present, is widely used in 3C electronic product, power battery and energy storage etc.
Field, this just has bigger demand to lithium battery pack package material.In lithium battery packaging field, there are mainly three types of encapsulation sides at present
Formula: cylinder, rectangular and Soft Roll.Cylinder, rectangular packaging mainly use aluminum hull and steel shell material, and Soft Roll mainly uses aluminum plastic film.
At this in three kinds of modes, for aluminum plastic film Soft Roll with advantages such as its lightweight, safety, the market share is increasing.Lithium electricity at present
Aluminum plastic film used in pond is divided into dry method and thermal method, and the structure of dry method is mostly PA/ adhesive/AL/ adhesive/CPP, the structure of thermal method
It is mostly PA/ adhesive/AL/MPP/CPP.The above structure is required to apply to adhesive, due to the increase of aluminum plastic film dosage,
The dosage of corresponding adhesive is consequently increased.
At present in the actual production process, in order to reduce production cost, part aluminum plastic film manufacturer starts self-dissolving glue, leads to
Normal 80 DEG C ± 5 DEG C of collosol temperature or more, revolving speed are greater than 100r/min, and usual dissolution time is 2~3h or so, when due to dissolution
Between it is too long, need to consume more electric energy；And high temperature quickly stirs, and has that there are higher security risks.
Summary of the invention
In order to solve the technical issues of technical background is previously mentioned, the present invention provides a kind of dissolution sides of acid modified polyolefin
Method dissolves acid modified polyolefin with organic solvent.
The technical solution adopted by the present invention are as follows:
A kind of dissolving method of acid modified polyolefin is mixed with the organic solvent of organic solvent (C1) and organic solvent (C2)
Close liquid (C) dissolution acid modified polyolefin (A).
Organic solvent C2 is first put into dissolution kettle in room temperature, revolving speed is adjusted, adds organic solvent C1, keeps its mixing equal
It is even；Then it is slow added into acid modified polyolefin A；After acid modified polyolefin A to be finished, revolving speed is adjusted rise simultaneously by heating
Height stops heating, then revolving speed is turned down when temperature reaches designated value, continues to stir 1h, whether observation acid modified polyolefin A
It is completely dissolved, if be not completely dissolved, continues stirring until being completely dissolved.
Materials of the invention are few, simple process, and saving of labor, time saving, material-saving do not pollute the environment.This method dissolution
Acid modified polyolefin A not only shortens dissolution time, improves production efficiency, while keeping solute effect more preferable, also makes to dissolve
The colloidal sol arrived has lower viscosity, is conducive to directly be used on the machine.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with molten in embodiment
Solution method, is described in detail technical solution.Based on the embodiments of the present invention, those of ordinary skill in the art are not making
Every other method obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
An embodiment of the present invention: a kind of dissolving method of acid modified polyolefin is, first by organic solvent C2 in room temperature
