Description of the Related Art Conventionally, a release paper base material for sanitary treatment articles, that is, a blood-sucking material which is a main body, is adhered via an adhesive to improve a releasability. As a base material of a release paper formed by applying a solution of lactic acid in an organic solvent such as toluene, rice pulp having wood pulp as a main raw material of 25 to 40 g / m 2 and a thickness of 35 to 6 is used.
A silicone solution, which is usually dissolved in an organic solvent such as toluene, xylene and hexane to a concentration of 1 to 15%, is coated on a 0 μm base paper with a coating machine such as a rod, knife, air knife or reverse roll coater to provide a coating amount of 1 to 12 g.

溢れトイレの内外を著しく汚す結果となる。The release paper for sanitary products is separated from the blood-sucking material at the time of use and only the blood-sucking material is used, and the release paper is discarded as an unnecessary material. However, it is coated on the base paper which is porous and rich in liquid absorbency. Silicone penetrates deeply into the base paper together with the solvent and hardens in the process of distilling off the organic solvent in the drying process, so the voids in the base paper are filled with silicone, the base paper becomes strong, and the wood pulp fibers become Not easily disaggregated in water. For this reason, if the release paper is intentionally or neglected during use and is discarded in the toilet bowl of the flush toilet, it does not disintegrate in the water and causes clogging of the pipe, which not only causes a poor flow of flush water in the pipe, but also dirt. Wash water containing water will overflow from the upper part of the toilet bowl, resulting in a significant stain on the inside and outside of the toilet.

It has not been.

As a result of repeated research, finally, a release paper substrate satisfying these requirements was obtained.

Prevent the penetration of the organic solvent solution of silicone into the base paper and the filling of the voids in the base paper with the silicone before the application of the organic solvent solution of silicone to the base paper of ~ 60 μm (hereinafter referred to as solvent barrier property). It has been found that forming a barrier layer made of a water-soluble substance for the purpose of exerting the effect of satisfying this requirement.

Can't do it at all.

の目的を達成するに至った。The present inventors have found that the base paper, the barrier layer made of a water-soluble substance and the silicone layer form three layers independent of each other, and that the barrier layer has the effect of blocking the permeation of the organic solvent. It was found that a barrier property can be imparted and the property of being easily disintegrated in water can be imparted, and as a result of continuing further research to establish a technique for forming such a barrier layer, the main component was a water-soluble polymer compound. The aqueous solution of
It was found that a water-soluble polymer compound forms a barrier layer having excellent solvent barrier properties without penetrating into the base paper by applying it as a foam-like paint up to 4.0 times, and for the first time The object of the present invention has been achieved by an inexpensive method.

る。On the other hand, as a means for forming three layers in which the base paper, the barrier layer made of a water-soluble polymer compound and the silicone layer are mutually independent, the base paper and a film containing a water-soluble polymer such as polyvinyl alcohol as a main component are attached. A method of combining them is also conceivable, but it becomes expensive due to complicated materials and processes, and it is difficult to apply this to a physiological treatment product.

ない。The water-soluble polymer compound used in the barrier layer of the present invention includes water-soluble synthetic polymer compounds such as polyvinyl alcohol and acrylamide copolymer, and water-soluble natural polymer compounds such as starch, carboxymethyl cellulose and casein. They can be arbitrarily selected and used alone or as a mixture, and are not restricted as long as they do not impair the requirements of Notification No. 28 “Physiological treatment article standards” presented by the Ministry of Health and Welfare on May 24, 1966. Further, a pigment or the like can be blended if necessary, but excessive blending is not preferable because it lowers the solvent barrier property of the barrier layer.

Can be used. However, in the method called the elution method, in which the surface of the coating film once formed is washed with a liquid and a specific component soluble in this liquid is eluted to form a foamed product, a void structure with a high degree of continuity is formed, which results in a solvent. Barrier properties cannot be imparted.

ることができる。For the purpose of improving the foamability and maintaining the foam formed stably, it is effective to add a surfactant called a foaming agent, a foam stabilizer and a foaming agent. These are represented by anionic surfactants such as ammonium stearate and sodium stearate, but are not particularly limited to these, and other anionic surfactants, nonionic surfactants, cationic surfactants, etc. It can be arbitrarily selected and used from the agents and the zwitterionic surfactants.

難となる。What is important in determining the foaming conditions and the compounding ratio of the surfactant is the value obtained by dividing the volume after foaming by the volume of the aqueous solution before foaming, that is, the expansion ratio is 1.5 to 4.0 times the volume. It is to whip so that it becomes. When the expansion ratio is less than 1.5 times, the aqueous solution penetrates into the base paper at the time of coating, and the intended solvent barrier property cannot be imparted. The amount of bubbles in the film becomes excessive, and the bubbles contact or coalesce with each other to remarkably impair the strength of the coating film, and it is very difficult to impart the solvent barrier property.

いか必要最少量にとどめるのが好ましい。The base paper used in the present invention uses bleached softwood and bleached hardwood as main raw materials, and is a fine paper produced by a Fourdrinier multi-cylinder type paper machine, Fourdrinth Yankee type paper machine, or round net paper machine. It includes medium-quality paper and single-glossy paper. In addition, the weight of rice is 25 to 40 g / m 2 , and the thickness is 35.
It is common to use a base paper having a thickness of up to 60 μm, but there are no strict restrictions on the pulp composition, the type and blending ratio of the filler, and the conditions for adding various chemicals. For the composition of used paper and chemicals that are not hygienic, see the Ministry of Health and Welfare Notification No. 28 above.
It should be avoided because it violates the No. “Physiological treatment product standards”. In addition, chemicals called sizing agents and water-proofing agents that are added for the purpose of imparting hydrophobicity and water resistance should be blended as little as possible or in the minimum necessary amount. It is preferable to stop.

層とシリコーン層の接着を強固にする作用をする。The above-mentioned barrier layer hardly penetrates into the base paper because the aqueous solution is in the form of foam containing a large amount of bubbles.
Since the bubbles are dispersed independently in the coating film, it has a property of being rich in a solvent barrier even though it is bulky. Further, the shallow unevenness due to bubbles on the surface of the barrier layer exerts the anchoring effect of the silicone layer coated on the upper side and strengthens the adhesion between the barrier layer and the silicone layer.

10% of sodium stearate was added to the 10% aqueous solution obtained by heating under heating as a concentration in the liquid, and foaming treatment was carried out for 40 minutes by a Cowles dissolver under the condition of 7,000 rpm. The expansion ratio of this aqueous solution was 9.3 times. This foamy aqueous solution was coated with a Meyer bar to form a barrier layer having a coating amount of 5.5 / m 2 . The evaluation results are shown in Table 1.
