2. removing the membrane waterproofing between copper sheet, prevents waterproof membrane access in the gap between copper sheet, influence the normal of mobile phone
It uses.
Wherein, the cleaning agent in the step c is that dehydrated alcohol and NY-120 gasoline are mixed according to what volume ratio 8:3 was mixed
Close cleaning agent.The subtle granule foreign such as dust or grease stain can all be remained on general mobile phone panel to be coated, these impurity meetings
Influence the waterproof performance and persistence of waterproof membrane, it is therefore desirable to be cleaned using cleaning agent, the present invention uses volume ratio for 8:3
Dehydrated alcohol and NY-120 gasoline mixing be used as cleaning agent, wiping cleaning treatment is carried out to mobile phone panel to be coated, can be had
Effect removal grease stain and dust impurity, the volatility of the cleaning agent is good, noresidue, will not generate to the component of mobile phone panel to be plated
Damage.
Wherein, the drying temperature in the step d is 35-40 DEG C, drying time 20-25min.Drying temperature is excessively high,
U.S. line paper can be made to soften, bonded with component, temperature is too low, then drying is not thorough, and drying rate is slow.Drying time is too low to be mentioned
High coating cost, drying time is too short, then drying is not thorough, and cleaning agent is easy residual, when of the invention drying temperature and drying
Between can effectively improve drying rate, improve the effect of drying, noresidue impurity.
Wherein, the step 2 chinese raw materials is Parylene type powder, and which includes N powder, C powder and D powder, institutes
The weight ratio for stating N powder, C powder and D powder is 1:3:2.
Parylene (Poly-p-xylene), synthetic fibre (Parylene) in trade name pa, is to pass through chemical vapour deposition technique
The general designation of the thin polymer film with poly- two methylenes penylene structure of preparation, it has extremely excellent electrical property, heat resistance, weather-proof
Property and chemical stability, mainly there is Parylene N(Parylene), Parylene C(poly) and
Parylene D(polydichloro-p-xylene) three kinds, abbreviation N powder, C powder and D powder of the present invention, the coating raw material powder that the present invention uses
The grain diameter of body is 30-70nm, and obtained waterproof membrane compactness is good.
The penetrating power of N powder (Parylene) is strong, effectively can form film, dielectric in various slots or pinholed surface
Constant is low, and coefficient of friction is extremely low, and lubricant effect is excellent.
C powder (poly) has excellent dielectric properties and physical mechanical property, has extremely low hydrone
With the penetrance of corrosive gas, deposition rate ratio N powder is fast, and corresponding penetrating power is lower than N powder.
D powder (polydichloro-p-xylene) has better material resources and electrical property at a higher temperature, while having preferably
Thermal stability deposits very fast with polymerization speed.
The working principle of plated film of the present invention is that solid paraxylene ring two-body heating sublimation is gaseous state ring under vacuum conditions
Two-body is cracked into movable monomer under gaseous state ring two-body high temperature, and activated monomer enters in vacuum film coating chamber, adsorb in matrix surface,

Wherein, the sublimation temperature in the step 2 is 120 DEG C -125 DEG C, evaporation chamber pressure 20-30Pa.
The core reaction of plated film be it is solid to toluene ring two-body heating sublimation at gaseous to toluene ring two-body, then occur
Cracking, 2 methylene-methene key fracture, generates the active monomer with free radical, and monomer joins end to end, intercouples, and is formed
Intermediate with free radical, intermediate polymerize again grows up, and forms the high-polymer molecule.The temperature of distillation is higher, coating raw material gas
Change is faster, and monomer molecule concentration is higher in vacuum coating room, and deposition polymerization is faster, but sublimation temperature is higher, activated monomer molecule
Kinetic energy is higher, and relative to the molecule of lower kinetic energy, these high-energy molecules have significant proportion to diffuse in cold-trap, without being deposited on
On the higher matrix of temperature, cause raw material availability low.It is more than rate of cleavage, part ring two-body if the rate of distillation is excessively high
Gaseous molecular has little time cracking and enters expansion chamber, is deposited directly to matrix surface, the degree of polymerization easy to form is lower, performance is poor
Porous polymer.
The deposition rate of monomer molecule can improve with the increase of pressure, but hypertonia, then deposit it is too fast, molecule at
Length is not fast enough, it may appear that misty film, compactness is insufficient, therefore the temperature and pressure evaporated needs a good balance,
It can obtain that compactness is good, the high waterproof membrane of raw material utilization rate.
Wherein, the cracking temperature in the step 3) is 685 DEG C -690 DEG C, and cracking chamber pressure is 8-10Pa.
As previously described, if the rate of cracking does not catch up with the rate of distillation, obtained waterproof membrane compactness is poor, waterproof
Effect is bad, and cracking temperature of the invention and pressure cooperate with above-mentioned evaporating temperature and pressure, influences each other, obtains this
The waterproof effect of the mobile phone waterproof membrane of invention is excellent, and the utilization rate of raw material is high.
Wherein, the substrate temperature to be coated in the step 4) is 25 DEG C -30 DEG C, and plating film pressure is 7-7.5Pa.
By the way that the study found that the growth rate of waterproof membrane is quickly increased with the reduction of substrate temperature, pressure is to film
The speed of growth also have a large effect, therefore mobile phone surface temperature selection of the invention, at 25 DEG C -30 DEG C, plating film pressure is 7-
7.5Pa is more conducive to the growth of waterproof membrane, reduces the usage amount of raw material, reduces coating cost.
Wherein, the membrane waterproofing in the step 4) with a thickness of 10-15 μm.Waterproof is lepthymenia, then the effect of waterproof is not
It is good, but waterproof membrane is blocked up, then not only wastes raw material, and the surface roughness that will cause film increases, and can reduce waterproof membrane instead
Waterproof performance.
Wherein, cold pump is opened when the temperature of vaporization chamber reaches 120 DEG C in the step 1).Cold pump refers to cryogenic pump, it
It is to be evacuated by condensing surface gas, is a kind of pumping equipment, is the present invention in order to obtain clean vacuum environment
Good using the effect of cold pump, vacuum environment is effectively regulated and controled, and improves the efficiency and effect of plated film.
Wherein, the temperature that cold pump before plated film raw material is put in the step 2 will reach -30 DEG C hereinafter, by control refrigeration pump
Temperature can be effectively controlled vacuum degree environment when putting plated film raw material, this method is good to the control effect of integrated artistic.
