Description
Technical field
The present invention relates to a kind of mould release membrance, particularly to a kind of reflective mould release membrance and preparation method thereof.
Background technology
Mould release membrance also known as antiadhesion barrier, be with polyethylene terephthalate plastics (be called for short PET),
Bidirectional stretching polypropylene film plastics (being called for short BOPP), vinyon (being called for short PE), carbonic acid
Ester plastics (being called for short PC), polystyrene plastics (being called for short PS), polypropylene plastics (being called for short CPP)
A kind of surface made for base material has the material of characteristic of low-surface-energy.By the viscose of next-door neighbour from release
When face is peeled off, can peel off or pipette separated type material easily, and not injure viscose physical property.Mould release membrance
Feature is surfacing, cleanliness factor height, following process dimensionally stable, and transparency and Color tunable are whole,
The thickness of thin film scope selectable with the kind of base material is wide.Utilize these features of mould release membrance can be to light
The deep processing learning the parts with electronic applications develops, thus it is the most automatic to adapt to this field
Changing production process, at present, mould release membrance can be widely applied for copper-clad plate, printed circuit board (PCB), electricity
The fields such as sub-adhesive.
Mould release membrance comprises base material film and release layer.Base material film surface at least one side is provided with release layer, with
Relatively low surface energy is provided.Base material film many employings paper, plastic sheeting are as material, and release layer is main
Silicon mixture is used to constitute.Typically it is used for industry adhesion zone or adhesive tape etc., to mould release membrance
Performance requirement relatively low, it is only necessary to its have high adherence and remain gluing rate, but be as industry neck
Developing rapidly of territory, the range of mould release membrance is increasingly wider, and there has also been its other performances must
Ask.
But, traditional mould release membrance mostly is transparent, translucent or coloured mould release membrance, due to its transparency
Height, is difficult to identification, at night or in the environment of the light is dusky, can affect processing and the use of mould release membrance.
Accordingly, it would be desirable to a kind of mould release membrance can in the environment of light intensity is more weak with strong reflecting effect, come
Strengthen the resolution of mould release membrance.
Summary of the invention
For solving the problem of above-mentioned existence, it is an object of the invention to provide a kind of reflective mould release membrance.Institute
Stating reflective mould release membrance, each component cooperates so that the release layer obtained can be spread evenly across basement membrane
On layer, and then it is viscous to make the mould release membrance obtained not produce when separating with the adhesion zone contacted or adhesive tape
Even；And it is added with reflective powder glass microballoon, owing to the high refraction action of glass microballoon and optically focused are at glass
On the special reflecting layer of microballon focus, light is reflexed to light source by transparent microballon by reflecting layer again
Near, so very bright reflection light can be seen at light source, at night or the environment that the light is dusky
Under, strengthen the resolution of mould release membrance, it is simple to the processing of mould release membrance and use.
For reaching above-mentioned purpose, the technical scheme is that
A kind of reflective mould release membrance, including base membrane layer, described base membrane layer is provided with release layer, described from
Type layer is formed by mould release coating, and described mould release comprises each component of following mass fraction: reflective powder:

And, described antioxidant is DI-tert-butylphenol compounds or Butylated hydroxyanisole；Described coupling agent is
Silane coupler；Described defoamer is glycol distearate or polyoxyethylene polyoxypropylene glycerin ether.
The preparation method of a kind of reflective mould release membrance, comprises the steps:
(1) weigh needed raw material by mass fraction, vinyl organosilicon resin and butyl acrylate are added
Enter in solvent and stir, add titanium dioxide and reflective powder, 0.5-1.5h is stirred at room temperature, then adds
Enter antioxidant, coupling agent, defoamer, after being warming up to 40-60 DEG C, continue stirring 0.5-1h
(2) gained mixed liquor in the one or both sides coating step (1) of base membrane layer, coating weight is
0.60-0.80g/m2, it is placed in drying baker, at 50-65 DEG C, is dried 6-20min, makes surface the most solid
Change, be finally shaped, rolling, obtain reflective mould release membrance.
The beneficial effects of the present invention is:
The reflective mould release membrance of one that the present invention provides, each component cooperates so that the release layer obtained
Can be spread evenly across on base membrane layer, so make the mould release membrance obtained with the adhesion zone contacted or glue
Adhesive tape does not produce adhesion when separating；And it is added with reflective powder glass microballoon, due to the high folding of glass microballoon
The effect of penetrating and optically focused on the special reflecting layer of glass microballoon focus, reflecting layer by light by transparent micro-
Pearl reflexes near light source again, so can see very bright reflection light at light source, at night
Evening or in the environment of the light is dusky, strengthen the resolution of mould release membrance, it is simple to the processing of mould release membrance and use.
