Description

TECHNICAL FIELD [0001] The present invention relates to a moisture-permeable and waterproof sheet which does not use a fixing member, a method of manufacturing the same, a method of manufacturing the same,

The present invention relates to a breathable and waterproof sheet excellent in breathability and waterproofness, which comprises upper and lower layers made of a nonwoven fabric or a fabric and a breathable film layer. More particularly, the present invention relates to a moisture-permeable and waterproof sheet which improves the handling performance and workability of an operator without using a fixing member to increase the watertightness of the moisture permeable and waterproof sheet on the roof.

The waterproof sheet material is an outer wall material or a roofing material which protects soundproofing, heat insulation and waterproof property in a wooden house and blocks rainwater entering from the outside, and has moisture permeability and waterproofness. Therefore, it is required to discharge the moisture generated in the indoor space efficiently, and also to be excellent in the resistance to fungus and corrosion.

In a roof structure of a building such as a wooden house, a plurality of rafters are alternately supported at a certain interval between the marquee and the upper half, and at the same time, the OSB structural plywood is laid on the rafters to form the sanjiwa. The roof waterproof sheet is a second waterproofing material that completely prevents water leaking into the roof due to tear crevices or cracks. It is required to be completely waterproofed by being the last waterproof sheet provided on the above-mentioned OSB plywood.

The waterproof sheet material mainly uses a fixing member such as a hammer, a taker, a stapler, and a nail for attaching to the OSB plywood used for a roof. A needle or nail of a stapler causes a gap such as a needle hole or a nail hole in the waterproof sheet material Waterproof effect is significantly reduced.

In order to solve the problems described above, the following methods have been proposed and used in the related art. First, an improved asphalt waterproofing sheet material of rubber type which does not use release paper has been introduced. However, this product also showed the limitation to use fixing member as in the conventional method. On the roof of the summer where the temperature is kept as high as 40 to 50 ° C, the adhesive force is obtained in the rolled state of the product, And the problem that the surface of the product should be attached to the OSB plywood in a state where the surface of the product is uneven or partly torn is derived and the waterproof effect is lowered and the waterproof sheet is put in a crumpled state or an overlapped place It is difficult to remove the product when reworking to fix the pinhole where the pinhole occurred, and the product has been damaged because the product has been damaged.

Further, a method of applying an adhesive between the OSB plywood and the waterproof sheet material to fix the waterproof sheet material without using a fixing member has been proposed.

However, it is difficult to apply the adhesive to the entire surface of the OSB plywood installed on the roof inclined at 60 to 70 °, and it is difficult to make the installation on the inclined roof due to the sticky adhesive applied on the front surface. If the waterproof sheet is installed incorrectly, it is impossible to re-work and the efficiency of the work is lower than that of the conventional method and the economical efficiency is remarkably lowered.

In addition, when the adhesive is applied on one side of the waterproof sheet material, it is rolled into a rolled state by inserting a release paper or a releasing paper, and if necessary, the product is used while removing the release paper or release paper when used as a waterproof sheet material. . This is done by removing the release paper or release paper when working on the roof, which peeled off release paper or release paper is piled up in front of the operator's feet and interferes with the operation. Particularly, the release paper or release paper has very slippery silicon coated on its front side If you walk in the wrong way, safety accidents such as falling accidents have arisen. Particularly, the stripping paper has become a double burden to be treated as garbage, and has received the outside of the market.

In addition, there is also a product in which a waterproof sheet is fixed on a part where a waterproof sheet is fixed to an OSB plywood to prevent a gap around the nail, and a waterproof sheet is overlaid on a part of a conventional product. However, Has been pointed out.

In addition, there is a tar-based waterproof sheet improved in waterproofness by immersing a waterproof sheet material, which is a conventional method, with asphalt, rubber or the like. However, such a tar-based waterproof sheet has a thickness of 2 to 5 mm due to deposition of tar, so that the weight of the roll product is heavy, so that it is difficult to handle by itself, and the handling property of the operator working on the roof is remarkably deteriorated. Tar-based modified asphalt as the main material of the product is also aimed only at the waterproof function, there was a problem in the effectiveness of the moisture permeability. Further, the waterproof effect is deteriorated by a gap generated by using the fixing member.

In order to solve the above-mentioned problems, it is an object of the present invention to provide a breathable and waterproof sheet excellent in breathability and waterproofness, which comprises upper and lower layers made of a nonwoven fabric or fabric and a breathable film layer.

The manufacturing method of the present invention further includes a step of pressing the rubber pressing roller 20 by rotating the steel roller 10 on the rubber pressing roller 20 as shown in FIG. . This is because, as the width of the adhesive application is wider and the amount of adhesive transfer is varied when the adhesive is transferred, unevenness of adhesive force between the left and right side and the center side portion is caused. This problem is caused by pressing the corroded groove of the gravure copper plate 30 Can be evenly pressed through the rubber pressing roller (20). However, there may be a phenomenon that the middle portion of the air shaft of the rubber pressing roller 20 is slightly raised at the left and right edges. In order to solve this problem, the conventional gravure copper plate 30 and the rubber pressing roller 20, It is preferable that the adhesive be applied more evenly by adding a chromium-plated auxiliary steel press roller 10 to the gravure copper plate 30 and the rubber platen roller.

When a desired amount of the adhesive is transferred to the gravure copper plate, the air permeable film having the upper and lower layers formed is passed between the rotating gravure copper plate and the rubber pressing roller located on the gravure copper plate. At this time, either one or both of the gravure copper plate and the rubber pressing roller In order to create the adhesive surface and the release surface, grooves of the engraved surface may be formed. When the rubber pressing rollers are pressed by the rubber pressing rollers, the portions where the unevenness is formed pass through the pressure sensitive adhesive or the releasing agent without being transferred by the pressure of the rubber pressing rollers. On the other hand, the portion where the grooves are formed may be transferred to the upper layer or the lower layer to form a plurality of adhesive or release surfaces. The concave grooves are formed in the gravure copper plate Or one or more rubber pressing rollers may be formed.

The engraved groove may be a piece of rare steel or a piece of ferrite, but is not limited thereto.
