Putting goods on the market, existing smooth surface PET silicone release film properties are difficult to the growth requirement for meeting cross cutting industry, and currently without adopting
It is coated with rotary press.
The content of the invention
The present invention provides a kind of coating process of reticulate pattern PET silicone release films, it is intended to solves existing PET silicone releases
The problem of film requires high to coating machine, and cost is high.
The present invention provides a kind of coating process of reticulate pattern PET silicone release films, comprises the following steps：
S1. PE is melted into film and is laminated into grid surface to PET base material, then by PE；
S2. light curable type silicone release agent is used, is tuned into the coating fluid with viscosity, it is using three-roll coating head that mould release is equal
Even is coated on base material；
S3. the base material for being coated with mould release is put into progress UV solidifications in rotary press；
S4. wound after completing solidification.
As a further improvement on the present invention, the manufacturing process of coating fluid includes in the step S2：
S21. by 100 parts of silicone release agent, light trigger 0.5-5 parts, antioxidant 0.5-3 parts, containing acrylic acid groups activity
Agent 10-50 parts, adhesion promoter 1-10 parts, are stirred and form, rotating speed 500-2000r/min.
As a further improvement on the present invention, the silicone release agent is silicone oil 200, and adhesion promoter is
ADD107。
As a further improvement on the present invention, the viscosity scope of coating fluid is 50-1000mPa.S in the step S2.
As a further improvement on the present invention, the coating process in the step S2 also includes：
S22. after coating fluid prepares, it is coated with three-roll coating head, base material needs sided corona treatment before coating, when exposed to focusing
Under ultraviolet light, the coating of silicone oil 200 being catalyzed can quickly crosslink reaction.
As a further improvement on the present invention, in the step S3, the rotating speed of rotary press is in more than 15m/min.
As a further improvement on the present invention, the stripping of the PE layers in the step S1 and the off-type force of PET base material in 1-3g
From power.
The beneficial effects of the invention are as follows：Increase reticulate pattern and process modification on its original base, relatively have with it significantly
Ultralight off-type force and device resource make full use of, the features such as reducing cost.
Brief description of the drawings
Fig. 1 is a kind of flow chart of the coating process of reticulate pattern PET silicone release films of the present invention；
Fig. 2 is a kind of product structure figure of the coating process of reticulate pattern PET silicone release films of the present invention.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.
As shown in Figure 1 to Figure 2, the coating process of reticulate pattern PET silicone release films of the invention, it is characterised in that including
Following steps：
S1. PE is melted into film and is pressed into grid surface to PET base material 2, then by PE layers 1；
S2. light curable type silicone release agent is used, is tuned into the coating fluid with viscosity, it is using three-roll coating head that mould release is equal
Even is coated on base material；
S3. the base material for being coated with mould release is put into progress UV solidifications in rotary press；
S4. wound after completing solidification.
Wherein, step S2 includes：
S21. by 100 parts of silicone release agent, light trigger 0.5-5 parts, antioxidant 0.5-3 parts, containing acrylic acid groups activity
Agent 10-50 parts, adhesion promoter 1-10 parts, are stirred and form, rotating speed 500-2000r/min.Wherein silicone release agent
For silicone oil 200, adhesion promoter ADD107.
S22. after coating fluid prepares, it is coated with three-roll coating head, base material needs sided corona treatment before coating, when exposed to poly-
Under burnt ultraviolet light, the coating of silicone oil 200 being catalyzed can quickly crosslink reaction.
The viscosity scope of coating fluid is 50-1000mPa.S in step S2.
In step S3, the rotating speed of rotary press is in more than 15m/min.
Peeling force of the off-type force of PE layers 1 and PET base material 2 in step S1 in 1-3g.
This programme introduces a kind of Novel coating technique of PET net line silicone release film, and this PET graining films directly can be with
Purchase, using light curable type silicone release agent, be tuned into certain viscosity, viscosity scope 50-1000mPa.S, using three-roll coating head,
Mould release is uniformly coated on base material, then by rotary press UV solidifications, winding.
The material surface that the method is produced has certain lines, and demand coating weight is small, stripping of the off-type force in 1-3g
From power.
As shown in Fig. 2 its surface is forged into grid configuration, compared with smooth flat, its effective contact surface is reduced, used
The dosage of mould release is relative to subtract it, and the contact area in during use and silica gel face diminishes, so that producing efficiently and ultralight release
Power.
Cross cutting printing industry does not have Conventional coaters, it is only necessary to can be coated using rotary press.Existing PET fluorine element
Mould release membrance is only coated on the basis of its PET, increases reticulate pattern and process modification on its original base herein, compared with it
There is making full use of for significant ultralight off-type force and device resource, the features such as reducing cost.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to is assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
