Abstract
The invention relates to matte release paper, comprising a substrate, wherein coating material is coated on the surface of at least one side of the substrate, raw material formula of the coating material comprises 71.2-90.8% of polymer, 0.2-1.2% of lubricating agent and 9-27.6% of fogging filler; the polymer is selected from polyethylene, polypropylene, PVC (polyvinyl chloride) and PET (polyethylene terephthalate); and the filler is solid particles with particle size of 3-20 microns. According to the invention, the matte release paper with stable release force and a pressure sensitive adhesive surface having a good haze effect can be produced, thus an adhesive moving surface can achieve low reflective effect. The matte release paper has the advantages that the production process is simple, equipment investment cost is low and operation is easy to carry out.
Description
Technical field
The present invention relates to a kind of cloudy surface release liners, belong to cloudy surface material technology field.
Background technology
Release liners is claimed barrier paper again, and separate paper is a kind ofly both can prevent the prepreg adhesion, can protect the not contaminated separate paper of prepreg again.
Release liners is will drench membrane material (like polyethylene, polypropylene) pouring film on body paper (base material) surface through drenching the film machine; Form the certain thickness leaching membrane layer of one deck; Again the silicone mould release is coated on the leaching membrane layer, let it can show extremely light and stable off-type force for various organic pressure sensitivity glue.
Different organic pressure-sensing glue are for example: the pressure-sensing glue of hot melt adhesive, acryl glue and rubber system etc.; The off-type force of required release liners is different; Viscosity to the glue of need isolated product is different, and the off-type force correspondence is adjusted, and makes it the off-type force that when peeling off, reaches extremely light and stable.
The flatness of the leaching membrane layer that prior art makes is high; Poor adhesive force between mould release coating and the leaching membrane layer; When release liners attaches with the pad pasting that is coated with trowel adhesive; Cause the mould release coating on the release liners to be taken away easily, thereby form the mould release coating area that is difficult to clean out, destroyed whole pure, the uniformity of pad pasting in the local surfaces of pad pasting by the bigger adhesive of adhesion.
Summary of the invention
The object of the invention provides a kind of cloudy surface release liners.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of cloudy surface release liners; Said cloudy surface release liners comprises a base material, and at least one side surface of this base material drenches film has the pouring membrane material, and this composition of raw materials that drenches membrane material is made up of the material of following quality percentage composition:
Polymer 71.2% ~ 90.8%;
Lubricant 0.2% ~ 1.2%;
Filler 9% ~ 27.6% hazes;
Wherein, said polymer is selected from polyethylene, polypropylene, polyvinyl chloride, PETG, polybutylene terephthalate (PBT); Said lubricant is selected from paraffin, white oil, stearic acid, stearate; Said filler is that particle diameter is 3 ~ 20 microns a solid particle.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the said filler that hazes is at least a in silica, calcium hydroxide, talcum powder and the calcium sulfate.The effect of filler of hazing is to make the roughness of drenching the laminated polyester film of film on body paper reach 1.000um ~ 5.524um.The filler selection that hazes standard is: fusing point is higher than the solid particle of polymer, such as selecting titania powder etc.
2, in the such scheme, said white oil is meant slab oil.White oil is the specialty minerals oil product of ultra deep refining, and it is that main component is the mixture of the positive isoparaffin of C16～C31, belongs to lube cut, and colourless, tasteless, nothing is smelt, and has chemical inertness and good light, heat endurance.
3, in the such scheme, said stearate comprises calcium stearate, dolomol, zinc stearate and odium stearate.
4, in the such scheme, said paraffin comprises atoleine and solid paraffin.
5, in the such scheme, the effect of said lubricant is the smooth property that improves when drenching film, improves the speed of drenching film of extruding.
6, in the such scheme, drench film and can extrude to drench on the film machine at single screw rod or twin-screw and carry out.
7, in the such scheme, the particle diameter of the said filler that hazes is 8 ~ 15 microns.
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect:
1, the present invention is drenched the film machine spoons fusion on the paper surface of body paper or single face leaching membrane paper pouring membrane material through extruding; Surface at body paper forms leaching membrane layer; On the even roughness face of cloudy surface leaching membrane layer, be coated with mould release then; The pressure-sensing glue glue face cloudy surface release liners that makes can make transfer when protection glue face after has concavo-convex uniformly, thereby makes the mist degree of glue face reach good effect; Further improve the fastness that combines between resin molding and the body paper.
2, the present invention can produce stable, the good cloudy surface release liners of pressure-sensing glue glue face mist degree effect of off-type force, makes transfer adhesive glue face reach low reflecting effect.Production technology of the present invention is simple, and the equipment input cost is low, and is easy to operate.
3, to select particle diameter for use be 3 ~ 20 microns solid particle in the present invention, thereby on base material, form coarse surface.When particle diameter will not have the effect of cloudy surface during less than 3 microns, when particle diameter can stop up the extruder head that drenches the film machine during greater than 20 microns.
