Abstract
The invention relates to fog face release paper and a preparation method thereof. The preparation method comprises the following steps of: a first step of respectively laminating a laminated layer on the surface at both sides of body paper of the release paper by a laminating machine and then cooling; a second step of coating a fog face coating with the thickness of 0.2 to 2 microns on either of the laminated layers; a third step of irradiating the fog face coating by ultraviolet rays, so that multifunctional acrylate monomers are subjected to polymerization under the action of an initiator; and a fourth step of coating a layer of release agent on the surface of the fog face coating. In the method, one laminated layer is coated with the fog face coating, so that after being processed, the surface of the laminated layer coated with the fog face coating is provided with a plurality of uniform concave-convex structures; then the surface of the laminated layer coated with the fog face coating is coated with a silicon release agent coating; the bottom surface of the silicon release agent coating permeates the positions of notches on the surface of the polyester fog face coating in a liquid state; and after being solidified, the silicon release agent coating is fixedly connected with the polyester fog face coating through the notches, so the bonding force is more firm and reliable.
Description
Technical field
The present invention relates to a kind of cloudy surface release liners and preparation method thereof, cloudy surface release liners that particularly a kind of adhesion strength is high, peeling force is adjustable and preparation method thereof.
Background technology
Release liners is claimed barrier paper, separate paper again, is mainly used in to paste the adhesive layer that is used for the protective tapes surface on the surface of adhesive tape.Existing release liners generally is to drench film one deck leaching membrane layer (material of employing mainly contains polyethylene) on the surface of release liners ground paper layer, and the surface coated one deck parting agent layer (material of employing is mainly silicone oil) at leaching membrane layer obtains release liners then.But because the leaching membrane layer flatness 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 present invention provides a kind of cloudy surface release liners and preparation method thereof, and purpose is leaching membrane layer and the not high problem of mould release coating adhesion that solves release liners.
For achieving the above object; First kind of technical scheme that the present invention adopts is: a kind of cloudy surface release liners; Stacked gradually for five layers by first leaching membrane layer, release liners original paper layer, second leaching membrane layer, cloudy surface coating and mould release coating and to constitute, the surface roughness of said cloudy surface coating towards the surface of said mould release coating is 2.821um～3.324um.
For achieving the above object, second kind of technical scheme that the present invention adopts is: a kind of its preparation method of cloudy surface release liners, mainly form by the following step:
The first step:, respectively drench film one deck leaching membrane layer with drenching the film machine, cooling then in the both side surface of release liners body paper;
Second step: coating one layer thickness is 0.2～2 micron a cloudy surface coating agent on any leaching membrane layer, and this cloudy surface coating agent is made up of the compound of following quality percentage composition:
Polyfunctional acrylic ester monomer 30～50%;
Initator 0.1～1%;
Solvent 45～66%;
Said cloudy surface additive is that particle diameter is at least a in the resin particle, aluminium oxide, magnesia, calcium oxide of 20 nanometers～2 micron;
Said polyfunctional acrylic ester monomer is at least a in methyl acrylate, ethyl acrylate, 2-methyl methacrylate, ethyl 2-methacrylate, methoxy poly (ethylene glycol) mono acrylic ester, alkoxide lauryl acrylate, acrylic acid stearyl, alkoxide nonyl phenol acrylic acid ester, epoxy acrylate, polyester acrylate, the polyfunctional group aliphatic urethane acrylate;
Said initator is benzophenone, para toluene sulfonamide, triphenyl phosphate or benzoin dimethylether;
Said solvent is toluene, ethyl acetate or positive butanone;
The 3rd step: adopt ultraviolet ray that said cloudy surface coating agent is shone, make said polyfunctional acrylic ester monomer under action of evocating, carry out polymerisation and obtain the cloudy surface coating;
The 4th step: at surface-coated one deck mould release of said cloudy surface coating.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said mould release coating is to be used for isolating adhesive on the adhesive tape to make it and the release liners bonding, thus require its not with adhesive generation cross-linking reaction, the material of its use is mainly silicone oil.
2, in the such scheme, said ultraviolet ray (UV) mainly is meant UVA, UVB and UVC.
3, in the such scheme, methoxy poly (ethylene glycol) mono acrylic ester (Methoxy Glycol 350 Monoacrylate; Methoxy Polyethylene Glycol 350 Monoacrylate; CH
3O (CH
2CH
2O)
nOCCH=CH
2N=8～33), alkoxide lauryl acrylate (Alkoxylated Lauryl Acrylate), acrylic acid stearyl (Stearyl Acrylate), alkoxide nonyl phenol acrylic acid ester (Alkoxylated Nonyl Phenol Acrylate), epoxy acrylate (Epoxy Acrylate), polyester acrylate (Polyester Acrylate), the polyfunctional group aliphatic urethane acrylate can be available from the chemical Co., Ltd of Sartomer (Guangzhou).
4, in the such scheme, resin can be natural resins such as rosin, styrax; Phenolic resins, Corvic etc. are synthetic resin.Resin has the branch of natural resin and synthetic resin.Natural resin is meant the amorphous organic substance by occurring in nature animals and plants secretion gained, like rosin, amber, shellac etc.Synthetic resin is meant the resin product that is obtained through chemical reaction through chemical synthesis or some natural products by simple organic.Synthetic resin is the main component of plastics.
5, in the such scheme, the material of said leaching membrane layer is PETG, polypropylene, polyethylene or polyvinyl chloride.
6, in the such scheme, said film is pet film, polypropylene film, polyethylene film, polyvinyl chloride or cast polypropylene film.
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect:
Because it is the leaching membrane layer of PE that the present invention is at first respectively drenched film one deck material to the two sides of release liners original paper layer (common paper); Coated polyester cloudy surface coating (material is a polyester) on therein the leaching membrane layer again; The surface has some even concaveconvex structures after treatment; In this surface coated silicon mould release coating, the notch place of said polyester cloudy surface coating surface is infiltrated in the bottom surface of silicon mould release coating under liquid state then, and silicon mould release coating is fixedly linked through notch and polyester cloudy surface coating after solidifying; Therefore, adhesion more firmly, reliably.But also can freely adjust the size of peeling force between silicon mould release coating and the release liners body paper through regulating the mist degree (being roughness) of cloudy surface coating.
