Abstract
The utility model relates to an isolation paper used for preparing chlor-alkali membranes, which belongs to the technical field of isolation paper manufacturing, and comprises a wood pulp layer and a coating layer. The coating layer is coated on the upper surface of the wood pulp layer; the thickness of the wood pulp layer ranges from 90g/m2 to 200g/m2; and the thickness of the coating layer ranges from 0.0005mm to 0.002mm. The isolation paper has the advantages: 1 being breathable and high-temperature resistant, 2 being flat, vertical, moisture-proof, high in strength and capable of completely meeting use requirement in the process of preparing the chlor-alkali membranes, 3 being stable in performance, easy to be cut according to needed specifications and convenient to be used, and 4 being simple in production process and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of barrier paper that is used for the chlor-alkali film preparation, belongs to release liners manufacturing technology field.
Background technology
Chlor-alkali industry is as follows with the main manufacture method of ionic membrane, and the ionic membrane basement membrane for preparing in advance is tiled on the heating source with barrier paper with strengthening the screen cloth lamination, and the effect by pressure or vacuum is combined with each other it.Patent CA1196888A1, US3770567, US3849243, US2002034904A1 etc. all mentioned the barrier paper of this special use, but this barrier paper are disposable product when introducing the manufacture method of ionic membrane, caused certain wasting of resources.
In addition, because ionic membrane is in recombination process, therefore operating temperature has relatively high expectations for the heatproof of barrier paper up to more than 300 ℃; And the vacuum suction ionic membrane preparation technology of present main flow, need barrier paper to have airing function; Therefore, conventional, repeatedly used pouring film barrier paper can't satisfy the instructions for use in the chlor-alkali film preparation process because heatproof and permeability are not enough.
Summary of the invention
The utility model provides a kind of that can reuse, high temperature resistant, vapor-permeable type chlor-alkali film preparation barrier paper at the deficiencies in the prior art.
Chlor-alkali film preparation barrier paper is characterized in that it is made up of wood pulp layer and coating, and coating is coated on the upper surface of wood pulp layer, and wood pulp layer thickness is 90～200g/m
2, coating layer thickness is 0.0005～0.002mm.
Described wood pulp layer thickness is 105～150g/m
2
Described coating layer thickness is 0.001～0.0015mm.
Described wood pulp layer upper surface fineness is Ra:0.8 μ～1.6 μ.
Wood pulp layer is made by pure wood pulp, contains other impurity and can cause heat resistance to reduce; Papery is pure more, heat resistance is good more.The too thin meeting of wood pulp layer thickness causes the barrier paper insufficient strength, tears easily under the tension force condition, has only thickness at 90～200g/m
2Scope in, could guarantee the realization of its function.
Described coated body composition is an Organosilicon Release Agent, can use Dow Corning Corporation to produce
The product of brand, Organosilicon Release Agent have ask when solidifying short, efficient is high, excellent specific properties such as effective are peeled off in solvent-free interpolation, pollution-free, simultaneously, self have good heat endurance and gas permeability, satisfy the requirement in use of chlor-alkali film fully.
Wood pulp layer is before applying isolating agent, need carry out press polish, make the smooth surface of wood pulp layer, closely knit, no paper hair, also guaranteed simultaneously 0 infiltration of isolating agent in coating procedure, when wood pulp layer upper surface fineness reaches Ra:0.8 μ～1.6 μ, coating layer thickness is that 0.0005～0.002mm can reach instructions for use, economizes in raw materials; In addition, the wood pulp layer after the surperficial press polish is after applying Organosilicon Release Agent, and through hot setting, the barrier paper of acquisition is smooth, well-pressed.In the preparation process of chlor-alkali film, when composite membrane when barrier paper is peeled off, peeling force is little, and barrier paper do not have the desiliconization phenomenon, therefore, this barrier paper is reusable.
The advantage of this barrier paper is: 1, be breathe freely, high temperature resistant; 2, smooth, wide, moistureproof, intensity is high, has satisfied the instructions for use in the chlor-alkali film preparation process fully, 3, stable performance, specification is cut as required easily, the convenient use; 4, production technology is simple, low cost of manufacture.
