Abstract
The utility model relates to kraft double-sided non-plastic release paper, which belongs to the technical field of composite material and solves the technical problems of non-reasonable design, easy bending and the like existing in the prior art. The utility model comprises a kraft paper layer, and is characterized in that a polyvinyl alcohol layer is composited on the kraft paper layer, a butylbenzene emulsion layer is composited on the other side of the kraft paper layer, a first silicone oil layer is composited on the polyvinyl alcohol layer, and a second silicone oil layer is composited on the butylbenzene emulsion layer. Compared with the prior art, the kraft double-sided non-plastic release paper has the advantages of reasonable design, simple structure, stable and reliable properties, good isolation and protection performances, low possibility of curling and good flatness, and is less susceptible to temperature and lighting.
Description
Technical field
The utility model relates to technical field of composite materials, especially relates to the two-sided nothing of a kind of ox-hide and moulds release liners.
Background technology
Release liners is to adopt the composite sheet that drenches film and be coated with the silicon technology co-production.Release liners of the prior art generally has three-layer structure, and ground floor base stock, the second layer are to drench film, and the 3rd layer is silicone oil.Because this release liners is the compound of three kinds of materials, and these three kinds of materials are subjected to the influence of temperature and humidity, and changing size can be different, so release liners can be influenced by humiture to deform.If temperature raises, the face elongation is big, and the paper elongation is little, and the release liners of sheet can be curled, and is curled to the paper face by face.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of heat-sealing adhering-resistant paper [application number: CN01274888.9], and one deck packing timber bed of material is arranged, and main feature is: this release liners is divided into sideband part and the middle band portion between the sideband part.Sideband partly is two-layer, and middle band portion is three layers.The ground floor of sideband part is the packing timber bed of material, side at the packing timber bed of material has the heat seal hot melt adhesive layer, the ground floor of band portion is all the packing timber bed of material in the middle of described, has polyvinyl alcohol layer in the same side of the described packing timber bed of material, has separation layer on polyvinyl alcohol layer.
Such scheme has improved the performance of release liners to a certain extent, but still exists above-mentioned technical problem.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, is easy to processing and manufacturing, and the two-sided nothing of ox-hide stable and reliable for performance is moulded release liners.
For achieving the above object, the utility model has adopted following technical proposal: the two-sided nothing of this ox-hide is moulded release liners, comprise layers of kraft paper, it is characterized in that, the one side of described layers of kraft paper is compounded with polyvinyl alcohol layer, another side in layers of kraft paper is compounded with the butadiene-styrene latex layer, is compounded with first silicon layer on polyvinyl alcohol layer, is compounded with second silicon layer on the butadiene-styrene latex layer.
Polyvinyl alcohol is an organic compound, and white plates, cotton-shaped or pulverulent solids are tasteless.Water-soluble, be insoluble to gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethanes, carbon tetrachloride, acetone, ethyl acetate, methyl alcohol, ethylene glycol etc.Be slightly soluble in dimethyl sulfoxide (DMSO).Polyvinyl alcohol is an important chemical material, has good performance when being used for paper coating.Butadiene-styrene rubber is a unsaturated rubber, is formed by butadiene and styrene polymerization, divides solution polymerized butylbenzene and breast poly-butylbenzene, has oil-filled and non-oil-filledly, and physical property is similar with other general purpose rubbers, and solid is flexible, density 0.95.
Mould in the release liners in the two-sided nothing of above-mentioned ox-hide, the thickness of described second silicon layer is greater than the thickness of first silicon layer.
Mould in the release liners in the two-sided nothing of above-mentioned ox-hide, described butadiene-styrene latex layer has double-decker.
Compared with prior art, the advantage that the two-sided nothing of this ox-hide is moulded release liners is: 1, reasonable in design, simple in structure, stable and reliable for performance, have the good isolation barrier propterty.2, be difficult for taking place to curl, planarization is good, and it is little influenced by temperature, illumination etc.
Description of drawings
Fig. 1 is the cross-sectional structure enlarged diagram that the utility model provides.
Among the figure, layers of kraft paper 1, polyvinyl alcohol layer 2, butadiene-styrene latex layer 3, first silicon layer 4, second silicon layer 5.
The specific embodiment
As shown in Figure 1, the two-sided nothing of this ox-hide is moulded release liners and is comprised layers of kraft paper 1.One side in layers of kraft paper 1 is compounded with polyvinyl alcohol layer 2, is compounded with butadiene-styrene latex layer 3 at the another side of layers of kraft paper 1, is compounded with first silicon layer 4 on polyvinyl alcohol layer 2, is compounded with second silicon layer 5 on butadiene-styrene latex layer 3.
The thickness of second silicon layer 5 is greater than the thickness of first silicon layer 4.Butadiene-styrene latex layer 3 has double-decker.
It is stable and reliable for performance that the two-sided nothing of this ox-hide is moulded release liners, has the good isolation barrier propterty; And be difficult for taking place to curl, planarization is good, and it is little influenced by temperature, illumination etc.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as layers of kraft paper 1, polyvinyl alcohol layer 2, butadiene-styrene latex layer 3, first silicon layer 4, second silicon layer 5 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
