Abstract
The utility model discloses solvent-free silicon oil ultrathin release paper which is simple in structure, attractive in appearance, ultrathin, cost-saving, and beneficial to production. The solvent-free silicon oil ultrathin release paper comprises a body paper layer, a priming coat and a silicon oil layer respectively from top to bottom, wherein the weight of the body paper layer is 18-28g/m<2>, the silicon oil layer is solvent-free silicon oil, and the weight of the release paper is 20-30g/m<2>. Compared with conventional release paper, the solvent-free silicon oil ultrathin release paper provided by the utility model has the following advantages that firstly, the solvent-free silicon oil ultrathin release paper is small in weight under the same area, raw material-saving, and achieves the purpose of saving energy; secondly, the solvent-free silicon oil does not contain solvents such as gasoline and methylbenzene, the phenomena such as spontaneous combustion and explosion in a production process are avoided, thus the solvent-free silicon oil ultrathin release paper is pollution-free, achieves the purpose of protecting the environment, and accords with the national and market demands; and thirdly, because the body paper layer is sufficiently thin, no overpressure needs to be carried out in the production process, manufacturing procedures are reduced, the manufacturing efficiency is increased, and the production cost is lowered.
Description
Technical field
The utility model relates to a kind of ultra-thin release liners of solvent-free silicone oil being applied on nappy, sanitary napkin, protection pad.
Background technology
Release liners is called again barrier paper, separate paper, on people's life, industrial paper, application is very extensive, existing release liners is divided into solvent silicone oil, solvent-free silicone wet goods release liners, wherein solvent silicone oil release liners comprises that three layers are respectively original paper layer, priming coat, solvent silicon layer from top to bottom, at the upper surface of original paper layer, is also printed with pattern.Its weight average is for being greater than 35 grams/m, and its solvent silicon layer bottom is shiny surface, and smoothness is less than 200S, and the smoothness of the non-shiny surface of original paper layer upper surface (being printing surface) is for being greater than 60S.The weight of this release liners integral body is large, and production cost is high, can not meet the demand in market.
Further, existing solvent-free silicone oil release liners is in process, must on body paper, coat industrial chemicals primary coat, and body paper grammes per square metre is high, smoothness is low, after need to carrying out at least one times superpressure, could coat solvent-free silicone oil reservoir thereon, owing to having more this procedure of superpressure, process is comparatively complicated, production efficiency is low.
Therefore be necessary to design a kind of release liners of new construction on the basis of existing release liners.
Utility model content
Problem to be solved in the utility model is, for the deficiency of above-mentioned technology, design a kind of simple in structure, good looking appearance, ultra-thin, save cost and be beneficial to the ultra-thin release liners of solvent-free silicone oil of production.
The utility model is that the technical scheme that its problem of solution adopts is:
The ultra-thin release liners of a kind of solvent-free silicone oil, comprise and be respectively original paper layer, priming coat, silicon layer from top to bottom, the weight of described original paper layer is 18～28 grams/m, and described silicon layer is solvent-free silicone oil, and the weight of described release liners is 20～30 grams/m.
Technique scheme also has the following technical scheme of improving: described priming coat is the mixture of polyvinyl alcohol and butadiene-styrene latex.The mixed proportion of polyvinyl alcohol and butadiene-styrene latex is 8～9: 2～1.The smoothness of described original paper layer is less than 50S.Described solvent-free silicone oil reservoir bottom surface is shiny surface, and its smoothness is greater than 650S.
The beneficial effects of the utility model are: compare and the utlity model has following advantage with traditional release liners: 1, the utility model weight under same homalographic is low, conservation, reached energy-conservation object 2, there is not gasoline, toluene equal solvent in solvent-free silicone oil, the phenomenons such as self-firing and self-explosion have been stopped to occur in production process, environment friendly and pollution-free, meet country and the demand in market; 3, because original paper layer is enough thin, in process of production without it is carried out to superpressure, reduce manufacturing procedure, improved working (machining) efficiency, reduce production costs.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the structural representation of the present embodiment.
The specific embodiment
With reference to Fig. 1, the ultra-thin release liners of a kind of solvent-free silicone oil provided by the utility model, comprise and be respectively original paper layer 1, priming coat 2, silicon layer 3 from top to bottom, upper surface at original paper layer 1 is also printed with pattern, the weight of described original paper layer 1 is 18～28 grams/m, and described silicon layer 3 is solvent-free silicone oil.
As preferred embodiment, the weight of described release liners is 20～30 grams/m.Described priming coat 2 is the mixture of polyvinyl alcohol and butadiene-styrene latex, and the mixed proportion of described polyvinyl alcohol and butadiene-styrene latex is 8～9: 2～1.Further, the smoothness of above-mentioned original paper layer 1 is less than 50S, in high-speed production process, is difficult for skidding; Above-mentioned solvent-free silicone oil reservoir 3 bottom surfaces are shiny surface, and its smoothness is greater than 650S, make that brightness is high, outward appearance is beautiful, texture is good.
Preparation method of the present utility model, its step comprises:
The above, it is only the utility model preferred embodiment, not the utility model is done to restriction completely, any simple modification, equivalent variations or decoration that every foundation technical spirit of the present utility model is done above embodiment, all belong to the scope of technical solutions of the utility model.
