Description
Technical field
The present invention relates to film production technology, and in particular to a kind of liquid film forming is combined flattening method and equipment.
Background technology
Tradition uses liquid spray technology in material surface formation layer of surface coating, has the disadvantage spillage of material than larger,
The bad control of face coat thickness, larger for ambient influnence, working environment is poor.Sprayed surface is easily by miscellaneous in environment
Matter influences, and increases later stage polishing operation, and yield rate is relatively low.Especially for the bad coating of levelability, form face coat and deposit
In rough striped, profile pattern, translucency requirement are not reached.
The content of the invention
Present invention aims at provide a kind of liquid film forming to be combined flattening method and equipment, the coating tentatively dried through baking oven
The material of liquid film, liquid surface coating material mobility is controlled, subsequently into the compound pressing stage.It is compound to flatten also
One layer of smooth mould release membrance of liquid film surface recombination with mobility.The effect of mould release membrance leads to the liquid film surface of out-of-flatness
Cross compound equally smooth with mould release membrance, while also requiring after the liquid coating drying and forming-film of surface, mould release membrance is easily from face coat
Sur-face peeling；Mould release membrance is used for the flatness of final surface filming.
To achieve these goals, the solution of the present invention is：
A kind of liquid film forming is combined flattening method, covers last layer liquid coating to the film surface for needing coating first, so
First time heating cure processing is carried out to liquid coating afterwards；Wherein, the film surface after the first time heating cure processing is applied
Layer is in noncurrent semi-cured state, and the surface of semi-cured state coating is and then attached to mould release membrance, is then fed into next
Process mould release membrance and film are rolled to coating carry out it is smooth determine thickness processing into subsequent processing complete curing of coatings handle.
Scheme is further：The semi-cured state is by soft up but not be stained with the shape of coating solution on hand with hand
State.
Scheme is further：It is described cover last layer liquid coating method be：Transported upwards with guide reel guiding film raw material
OK, one constantly in masking liquid bucket dipping liquid coating rubber roll in guide reel front end with the side opposite with guide reel rotation direction
To rotation, coating is overlayed on film surface by the adhered film of rubber roll adjustable-tightness in the horizontal direction.
Scheme is further：Applied from first time heating cure processing to the semi-cured state that is attached to mould release membrance
Layer surface, be then fed into subsequent processing mould release membrance and film are rolled to coating carry out it is smooth determine thickness handle be uninterrupted work
Skill flow, wherein, coating handles to export to from first time heating cure smooth determine the temperature drop that thickness handles to be not more than 5 Celsius
Degree.
Scheme is further：The completion curing of coatings is the step of handle：Determine smooth after thickness processing, with release
The film of film sends into a baking oven and carries out heating cure again, is wound as semi-finished product；Then semi-finished product are unreeled again
One baking oven of feeding heats, mould release membrance is rolled out to the film product to form coating.
A kind of equipment for realizing methods described, including frame, are provided with the former film let off roll of film, former film masking liquid in frame
Guide roller, is provided with former film liquid coating device by masking liquid guide roller, is sequentially set after masking liquid guide roller along film trend
Once baking oven, mould release membrance attach roller, smooth thickness to roller, secondary baking oven and wind-up roll；
Wherein：Baking oven is used to carry out liquid coating semi-solid preparation processing, institute to the film of the upper liquid coating of coating
State mould release membrance and attach roller for dredging the surface that mould release membrance is attached to semi-solid preparation liquid coating, the smooth thickness is to roller for pasting
The film semi-solid preparation liquid coating of attached mould release membrance smooth determine thickness and handle extrusion process, the secondary baking oven and wind-up roll
Wait to do final mould release membrance for winding after solidifying the smooth film semi-solid preparation liquid coating determined after thickness processing extruding again
Separating treatment.
Scheme is further：The former film masking liquid guide roller is be arranged in parallel by upper roller and lower roll to be constituted, and former film is arrived through lower roll
Upper roller is conveyed；Wherein, upper roller level is taken in former film inner side and set with lower roll vertical line in 15 to 30 degree angles；Also, the original
Film liquid coating device includes a masking liquid bucket and a rubber roll, and rubber roll is arranged on masking liquid bucket by a movable frame, rubber roll
Few half is in masking liquid bucket, and rubber roll and lower roll parallel contact, a motor drive rubber roll to rotate, by adjusting movable frame, adjust
Whole rubber roll and the horizontal tightening degree of lower roll.
Scheme is further：Former film conveying correction dress is provided between the former film let off roll and former film masking liquid guide roller
Put.
Scheme is further：Between two rollers that the smooth thickness includes being oppositely arranged up and down to roller, two of which roller
The screw rod that is set by two ends of gap can adjust, scale value is provided with adjusting screw rod.
Scheme is further：Infrared add is respectively arranged with baking oven and secondary baking oven on the upside of by film
Heat pipe.
The technology of the present invention formation makes the coating formation skin covering of the surface without levelability smooth, transparent, while the thinner thickness of film,
Film strength is also increased while reducing raw materials consumption.Liquid film is combined flattening technology and is applied to spray painting, disappears with paint
Consumption is few, the characteristics of environmental pollution is small.
The technology of the present invention overcomes spray painting wastage of material big, and greatly, percent defective is high, follow-up polishing operation working environment for ambient influnence
The shortcoming of difference, it is relatively thin to form paint film, and raw material are lost small.It is smooth that liquid paint film is combined flattening technology formation thickness uniform outer surface
Paint film.
