Abstract
The invention relates to a reflecting scratching-resistant release film, which is characterized by comprising a base film layer, wherein a release layer is arranged on the base film layer; the release layer is formed by coating a release agent; the release agent is prepared from the following ingredients in parts by mass: 20 to 30 parts of reflecting powder, 10 to 25 parts of vinyl organic silicon resin, 5 to 10 parts of fluorocarbon resin, 3 to 8 parts of nanometer aluminum oxide, 1 to 5 parts of titanium dioxide, 0.1 to 3 parts of antioxidant, 0.5 to 1.5 parts of antifoaming agents, 0.1 to 1 part of adhesion promoters and 15 to 30 parts of solvents. The reflecting scratching-resistant release film has the advantages that the adhesion cannot be generated when the obtained release film is separated from a contact adhesion belt or bonding belt; meanwhile, fluorocarbon resin and nanometer aluminum oxide are contained, so that the release film has high scratching resistant capability; reflecting powder and the glass microbeads are added, so that the recognition degree of the release film is enhanced at night or in dark lamp light environment; the processing and the use of the release film are convenient.
Description
Technical field
The present invention relates to a kind of mould release membrance, particularly to a kind of reflective anti-scratch mould release membrance.
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 anti-scratch mould release membrance.
Described reflective Anti-static release liner, each component cooperates so that the release layer obtained can uniformly be coated with
It is distributed on base membrane layer, and then makes the mould release membrance obtained when separating with the adhesion zone contacted or adhesive tape
Do not produce adhesion, contain fluorocarbon resin and nano aluminium oxide simultaneously, make mould release membrance possess the strongest anti-scratch
Ability；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 glass microballon focus, light is reflexed to light by transparent microballon by reflecting layer again
Near source, so very bright reflection light can be seen at light source, at night or the ring that the light is dusky
Under border, 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 anti-scratch mould release membrance, including base membrane layer, described base membrane layer is provided with release layer, institute
