Abstract
The disclosed a kind of color release film of the utility model, is composited by basal layer and parting agent layer, and described basal layer is one-body molded by the first pet layer sequentially joining, Masterbatch layer and the second pet layer.The utility model has improved a kind of color release film that can use lastingly, off-type force (3-300g/25mm) in extensive range, and residual to connect rate higher, can ensure to be greater than 95% convenient for production; This mould release membrance, in the time of actual peeling off, can better be differentiated the polyester rete of separated type material and the polyester rete of adhesive tape, has good distinguishing; Environment is little on the impact of its peeling force, and non-metastatic is also excellent, and residual to connect rate high; The two sides of polyester film all can be coated with the mould release membrance forming as main coating taking curing type silicone oil, gets final product dual coating release layer, and use field is more extensive; Release layer can be repeatedly practical, significantly reduced cost.
Description
Technical field
The utility model relates to a kind of color release film.
Background technology
Mould release membrance taking polyester film as base material is widely used in the manufacture of various display component parts, various optical applications, adhesive tape etc. because of its excellent characteristic.General mould release membrance material is to reach release effect in surface-coated one deck parting agent layer of transparent polyester rete.Because polyester rete is transparent, be difficult in use differentiate the polyester rete of separated type material and the polyester rete of adhesive tape.
Utility model content
The purpose of this utility model is to provide a kind of color release film.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of color release film, is composited by basal layer and parting agent layer, and described basal layer is one-body molded by the first pet layer sequentially joining, Masterbatch layer and the second pet layer.
Applicant finds after deliberation: if separately dope layer is directly coated on pet layer, easily occur the phenomenons such as dope layer layering, can not repeatedly use; And can only be coated with (the dope layer back side) by one side in the time doing release processing, the use of some two-sided mould release membrances is just restricted; In the time of coating colored paint, easily workshop and surrounding enviroment are polluted, because most coating will be dissolved in benzene or ketone equal solvent, these solvents are harmful; Applicant finds after deliberation using the first pet layer, Masterbatch layer and the second pet layer coextrusion mold as integrative-structure, efficiently solves that dope layer comes off, range of application is wide and the problem such as environmental pollution.Above-mentioned color release film is convenient for production, off-type force is in extensive range (3-300g/25mm), residual to connect rate higher, can repeatedly use.
Above-mentioned PET refers to PETG.
In order to improve the flatness on pet layer surface, described the first pet layer is not provided with the first priming coat with the one side that Masterbatch layer joins; Described the second pet layer is not provided with the second priming coat with the one side that Masterbatch layer joins.One deck that the first priming coat and the second priming coat can only be established wherein can also two-layerly all be established, and the kind of silane coupling agent is determined according to needs of production, has kind more than 20, most acrylic compounds that adopt.
Before above-mentioned primary coat one-off drawing in pet layer preparation process finishes, second step stretches, implementing coating processes, after primary coat is processed, pet layer surface smoothness increases substantially, widen the purposes of polyester film, can implement release coating, sclerosis coating, the sub-light processing of diffusion coating etc., these several embodiments are off-line coating.
The thickness of the first priming coat and the second priming coat is all not more than 0.1 μ m.Can ensure like this bond strength of pet layer and parting agent layer, not affect again overall serviceability.
The first priming coat is not provided with the first parting agent layer with the one side that the first pet layer joins, and the second priming coat is not provided with the second parting agent layer with the one side that the second pet layer joins.The coating of above-mentioned two-sided parting agent layer, has widened the scope of application of above-mentioned color release film.
The thickness of the first parting agent layer and the second parting agent layer is 0.2-0.3 μ m.Can meet so general demand, save material simultaneously.
In ultralight mould release membrance, the thickness of the first parting agent layer and the second parting agent layer is all preferably 0.6 μ m.
The thick 20-75 μ m of the first pet layer, the thick of Masterbatch layer is 10-28 μ m, the thick of the second pet layer is 20-75 μ m.Can be used in better like this in electronics cross cutting industry.
The utility model has improved a kind of color release film that can use lastingly, off-type force (3-300g/25mm) in extensive range, and residual to connect rate higher, can ensure to be greater than 95%, convenient for production; This mould release membrance, in the time of actual peeling off, can better be differentiated the polyester rete of separated type material and the polyester rete of adhesive tape, has good distinguishing; Environment is little on the impact of its peeling force, and non-metastatic is also excellent, and residual to connect rate high; The two sides of polyester film all can be coated with the mould release membrance forming as main coating taking curing type silicone oil, gets final product dual coating release layer, and use field is more extensive; Release layer can be repeatedly practical, significantly reduced cost.
