Description
Technical field
The present invention relates to a kind of film-forming method field, specially a kind of production method of the cover layer with fire resistance.
Background technology
Cover layer is applied in cell phone lines, and opponent's machine can play a very good protection, but existing cover layer
Easy aging at high temperature, and easily burning, bending property are also poor, cause cover layer to be easily broken, and make the reduction of mobile phone service life.
The content of the invention
It is an object of the invention to provide a kind of production method of the cover layer with fire resistance, to solve above-mentioned background
The problem of being proposed in technology.
The purpose of the present invention is achieved by following technical proposals:A kind of production of the cover layer with fire resistance
Method, is made up of following steps：
（1）The first step：Sorting, chooses resin 40%, solvent 25%, inserts 20%, acrylic acid 5%, polyimides 5%, auxiliary agent 3-4%
Compare raw material with pigment 1-2% weight；
（2）Second step：Slurrying, will（1）The middle raw material chosen uniformly is mixed, according to demand from suitable pigment, and
Heated in whipping process, heating-up temperature is 80-100 degrees Celsius；
（3）3rd step：Film, will（2）In the slurry that mixes produced by film-making machine；
（4）4th step：Cooling, will（3）The film of production is cooled down by cooling chamber, and cooling room temperature is 15-20 degrees Celsius；
（5）5th step：Finished product, will（4）The film of middle cooling is rolled bundled by the progress of wound membrane machine.
In a preferred embodiment of the invention, the first step（1）Middle solvent is esters solvent.
In a preferred embodiment of the invention, the 4th step（4）Exhaust fan is installed in middle cooling chamber.
In a preferred embodiment of the invention, the 5th step（5）Middle wound membrane machine is that full-automatic wound membrane takes film one
Machine.
The beneficial effects of the invention are as follows：A kind of production method of the cover layer with fire resistance, solves existing skill
The problem of cover layer poor flame retardant properties in art, easy fracture, easy aging, while the present invention implements simple, adapt to regional.
