Description
Technical field
The present invention relates to technical field of coatings, the mute black coatings of specially a kind of mobile phone inner member.
Background technology
Coatings have the coating of good electrical insulation, and it has good electrical property, hot property, mechanical performance and chemistry
Performance, currently on the market high-end handsets inner member use metal material, new choose is proposed to coating in terms of insulating properties
War.
Existing coatings use epoxy phenolics as raw material more, produce the colored varnish, for existing environmental regulation increasingly
Strict and performance requirement is more and more tighter, and the coating can not meet mobile phone inner member insulating properties, cosmetic requirements.
The content of the invention
With mute black coatings, its main purpose it is in mobile phone it is an object of the invention to provide a kind of mobile phone inner member
Component provides excellent insulating properties, aesthetic property, while provides certain covering for material is bad.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of mute black coatings of mobile phone inner member, its main constituents and weight proportion are polyester resin：45-48, absolutely
Edge carbon black：1.5-2.5, barium sulfate：9-10, levelling agent：0.1-0.3, amino resins：12-15, adhesive force auxiliary agent：2.5-3, vinegar
Acid butyl ester：10.9-11.5 ethyl acetate：10-10.9 flatting silica：2-2.5.
Preferably, the adhesive force auxiliary agent is propyl trimethoxy silicane.
Preferably, the flatting silica is using Lasaxing Oilfield coated fertilizer.
A kind of mobile phone inner member preparation method of mute black coatings, it is mainly included the following steps that：
（1）Stock：Polyester resin, insulate carbon black, barium sulfate, levelling agent, amino resins, adhesive force auxiliary agent, butyl acetate, acetic acid
Ethyl ester and flatting silica carry out stock of weighing according to above-mentioned weight proportion；
（2）Batch mixing material：Sequentially added in container levelling agent, amino resins, adhesive force auxiliary agent, butyl acetate, ethyl acetate,
Flatting silica, insulation carbon black, barium sulfate, polyester resin, are stirred, final mixture is ground will to specified fineness
The coating asked；
（3）Performance test：From mobile phone inside gadget sample, coating made from spraying, after drying, it is strong to carry out the breakdown of insulated paint paint film
Degree determination method and the resistance to electric arc determination method of insulated paint are detected, and meet examination criteria, 150 DEG C of high temperature solidifies to be had after magnesium alloy
There are excellent aging resistance, water-fast, resistant to chemical etching, impact resistance；
（4）Finished product packing：Step will be passed through（3）The coating of performance test carries out finished product packing.
The beneficial effects of the invention are as follows：Main purpose is to provide excellent insulating properties, aesthetic property for mobile phone inner member, simultaneously
Certain covering is provided for material is bad, 150 DEG C of temperature solidifies has excellent aging resistance, water-fast, chemically-resistant after magnesium alloy
Burn into impact resistance.
