Present invention also offers a kind of application of the benzene emulsion be coated on stationery base material, benzene emulsion is applied to and is coated on stationery base material, and benzene emulsion glue spread is 2-15g/m
2± 10%, stationery base material is formed the isolated protective layer of waterproof, grease proofing infiltration.
The method that described benzene emulsion is coated on stationery base material is: on stationery base material, be coated with the above-mentioned benzene emulsion coating prepared of at least one deck, to form the isolated protective layer of this substrate outer surface, described benzene emulsion glue spread is 2-15g/m
2± 10%.Concrete coating process is: adopt anilox roll or wheat tooth rod above-mentioned benzene emulsion to be coated the outside surface of stationery base material, solidification value when being wherein coated with is 80-120 DEG C, and benzene emulsion glue spread is 2-15g/m
2± 10%, surface covered is 15-90 ± 5m/min.
Described benzene emulsion coats the process after stationery base material:
One, stationery base material is placed more than 24 hours after coating benzene emulsion.
Two, the one side that stationery base material has been coated with benzene emulsion at it immediately after coating benzene emulsion continues painting fabric aqueous or oiliness silicone oil (parrots face to prevent from another side glues after pressure-sensitive acrylate, cause and be difficult to resolve volume), another surface coated pressure-sensitive acrylate adhesive of stationery base material is to form the adhesive-layer of stationery base material internal surface, after drying rolling, namely rewinding itemize forms stationery base material adhesive tape.
Three, stationery base material is after coating benzene emulsion, first in the one side that stationery base material is coated with benzene emulsion after printing pattern layer, at painting fabric aqueous or oiliness silicone oil, then at another surface coated pressure-sensitive acrylate adhesive of stationery base material to form the adhesive-layer of stationery base material internal surface, after drying rolling, namely rewinding itemize forms stationery base material adhesive tape.
Wherein, the above-mentioned method being coated with benzene emulsion on stationery base material is: adopt anilox roll or wheat tooth rod above-mentioned benzene emulsion to be coated the outside surface of stationery base material, solidification value when being wherein coated with is 80-120 DEG C, and benzene emulsion glue spread is 2-15g/m
2± 10%, surface covered is 15-90 ± 5m/min.
Owing to being coated with water-based or oiliness silicone oil at stationery substrate backside, prevent silicone oil from penetrating into stationery substrate surface, cause the performance of pressure sensitive adhesive to change, therefore coating benzene emulsion forms coating and substantially increases the anti-permeability of stationery base material.
The present invention prepares benzene emulsion owing to adopting vinylbenzene, butyl acrylate etc. for raw material, and is directly coated by formulated benzene emulsion on the outside surface of stationery base material, uses using the isolated protective layer as adhesive tape.Because benzene emulsion is a kind of organic polymer, at high temperature can there is polymerization crosslinking reaction, through drying the resilient coating of formation one deck, (concrete reason is the benzene emulsion of stationery substrate outer surface: butyl acrylate and vinylbenzene at high temperature polymerization reaction take place, forms the sticking coating of tool; Polyvinyl alcohol is auxiliary forms coating, and can reduce the viscosity of coating, thus generation has micro-sticky coating), so for the production of in adhesive tape process, insulation blocking effect can be played.Meanwhile, reduce coating viscosity through auxiliary the formation in coating procedure of polyvinyl alcohol, avoid producing paper and glue rotten problem.
The stationery base material stabilizing quality of benzene emulsion coating prepared by application the present invention, do not occur sticky rotten and there is certain glossiness and pliability.Due in last handling process, add wax emulsion, because wax emulsion has glossiness-giving effect, make the benzene emulsion coating after drying have certain glossiness; Meanwhile, again owing to adding benzoic ether in last handling process, because benzoic ether can soften certain coating hardness, so make the stationery base material of drying rear benzene emulsion coating have certain pliability.
The stationery base material being coated with benzene emulsion of the present invention can also substitute leaching membrane layer effect.Because the stationery base material adhesive tape of general film is because be difficult to keep the skin wet, in bake process, paper is caused easily to be out of shape.And benzene emulsion prepared by the present invention is coated on and forms coating after on stationery base material (surface because of the stationery base material adhesive tape of general film is rete, film material can not moisture in absorbed air), and make paper not easily not yielding in drying course, and be beneficial to environmental protection.
The preparation method of benzene emulsion of the present invention is simple, preparation time short (in 8 hours), thus effectively simplifies its progress and the production cost reducing adhesive tape.
Adhesive tape good stability made by the benzene emulsion utilizing the present invention to prepare, not easily occur paper glue rotten, come unstuck or degradation problem under physicals, adhesive tape qualification rate improves greatly, efficiently solves that existing adhesive tape easily permeates, Product processing operation is many, qualification rate is low and the problem such as production cost is high.
In a word, benzene emulsion preparation technology of the present invention rationally, stable performance, production cost is low, isolation anti-permeability is good, has certain economic benefit, can be widely used in various sealing or stickup field, is particularly useful for being used as stationery base material adhesive tape etc.
