The present invention is characterized in that the base material is in a plastic film; the separated coating film is formed by coating solvent type organosilicon coating material, drying the coated material and solidifying the dried material; the solvent type organosilicon coating material comprises the raw materials of 10 to 70 wt% of organosilicon resin coating material, 29.5 to 89.5 wt% of organic solvent, 0.03 to 0.1 wt% of catalyst, 0.03 to 0.1 wt% of anchoring agent and 0.1 to 0.7 wt% of bridging agent. The separated coating film has the advantage of low cost; the separated coating film can be used for a rapid packing machine.
Description
Technical field
The present invention relates to a kind of separated coating film and manufacture method thereof.
Background technology
The leading product that do not adhere to packing in the market are to be the separate-type paper of base material with the paper, such leaves the section bar material and is widely used, the paper substrate of the attaching self-adhesive label that for example daily being seen stationery adhesive label is used, all belong to this types of material, be antiseized coating layer to be arranged at paper surface, promptly release dope layer.
Because separate-type paper is a base material with the paper, has following shortcoming:
(1) paper need consume a large amount of timber, is unfavorable for environmental protection.
(2) because paper is a porous material, have very strong adsorptive power, make release coating can infiltrate through paper inside, cause the coating consumption height of unit surface, cost increases.
(3) can not be used for the Fast Packet installation.
Summary of the invention
The problems referred to above at existing separate-type paper exists the object of the present invention is to provide a kind of novel separated coating film, and this separated coating film has environmental protection, cost is low and be suitable for the advantage that Fast Packet is installed.
Separated coating film provided by the invention, the release dope layer that is applied by base material and substrate surface constitutes, described base material is a plastics film, described release dope layer is applied and dries and solidify to form by solvent-type organosilicon coating, and described solvent-type organosilicon coating becomes by the preparation of raw material that contains following weight content: solid content is organic siloxane paint 10-70%, organic solvent 29.5-89.5%, catalyzer 0.03-0.1%, anchoring agent 0.03-0.1% and the bridging agent 0.1-0.7% of 20-40%; The thickness of described substrate plastic film is 8-250 μ m.
Described organic solvent can be toluene, No. 120 gasoline, heptane or other aliphatics or aromatic solvents.
Described catalyzer is preferably the platinum catalyzer.
Described anchoring agent is preferably single silicon anchoring agent.
Described bridging agent can be the dimethyl siloxane bridging agent.
Described base material film can be polypropylene film (BOPP), polyester film (PET).
Described release dope layer can be coated on the single or double of described substrate plastic film.
The present invention also provides a kind of manufacture method of separated coating film, and this method comprises the steps: that (1) adds organic siloxane paint in the organic solvent mixes and make its dissolving, adds bridging agent, catalyzer and single silicon anchoring agent more successively, stirs; (2) substrate plastic film is carried out corona treatment, release coating is evenly shifted being coated to the substrate plastic film surface, surface covered be 50-250 rice/minute; (3) heating, drying, bake out temperature are 120-160 ℃, and drying time is 10-50 second, make release coating reaction and curing.
Preferred hot blast of drying mode in the described step (3) and far-infrared heating oven dry.
The preferred reverse roll kiss of coating method in the described step (2) coating method, with other roller problem of coating pollution in the traditional coating method of effective solution, and the difficult problem of coating coating lack of homogeneity.
The preferable glue spread of described release coating on the plastics film surface is 0.2-1.5g/m
2
This separated coating film of the present invention, compare with existing separate-type paper and to have following advantage:
1, with the plastics film be base material, make antistick layer with the release coating of special formulation, not only have excellent do not adhere to, easy stripping performance, and be highly suitable in the high-speed packaging field and use;
2, make base material with plastics film, have extraordinary transparency and gratifying luster performance;
3, have less electrostatic adhesion, be not easy to adsorb dust;
4, because plastics film is low to the adsorptivity of coating, the glue spread of release coating is significantly less than with the paper glue spread of coating of the separate-type paper that is base material, so have excellent material property price ratio, manufacturing cost reduces greatly.
5, less quantitative (spendable area on the unit weight), the product of same weight, usable floor area increases greatly.
