TH5477B - A sealant material made of clay that swells at water. And / or impermeable oil - Google Patents

Abstract

This invention provides a method for producing a water and/or oil impermeable sealant in the case of thrusting the swelled clay into position between the backing layer and the non-fibrous covering layer. woven The puffy clay is added to the flat side of the cover layer at the same time that the cover layer is applied. After that, the swelled clay in the cover layer is further moistened and dried. As defined in the modified form of this invention, the backing material is non-woven, woven, knitted fabric and/or film only, the film is synthetic resin film, fabric or paper reinforced synthetic resin film and Large pore non-woven material or wavy woven filament non-woven material or large pore non-woven material or wavy filament non-woven material. Overlapping or irregularly arranged non-woven fibrous material on which swelled clay is sprinkled in powder form. It is incorporated by stabilizing, dampening and drying. However, knitting and/or sewing may also be used instead of needle punching.

Claims (7)

1. A method for the continuous production of water and / or oil impermeable sheet materials that comprise the substrate layer. Inflatable clay layer Especially bentonite And cover material layer At least one of those material layers. It is a non-woven fiber material. And have to put the clay to inflate at Powdered or granular, dried down to the substrate The cover material is placed on top of it. And has adopted three layers of material That has gone through a needle thrust machine to aim for the material layer The supports and cover layers are bonded together by a unique needle thrust where before the needle is inserted, blistered clay is inserted. In the form of powdered substances To the upper surface of the covering consisting of non-woven fiber materials And stabbed the material from the layer Then make that clay An inflation that is pierced by a needle into that layer of covering material. With water to form clay, then dry again and if desired, then process to To the substrate layer with appropriate methods 2. The method, as held in claim 1, is unique in that the substrate layer is film or by Especially is fabric 3. Methods for producing water and / or oil-based sealant materials Continuously impermeable as classified as containing fibrous material Non-woven and puffable clay Which are unique to A porous structure consisting of a perforated non-woven fiber material is adopted. Large porosity and fiber connections Or even non-woven material Not connected as wavy fibers can not intersect without Get extra connections Or non-woven fiber material Disordered and placed on a substrate made of non-woven, woven or knitted fabric and / or synthetic resin film based substrates. Reinforced synthetic resin film Strong with cloth or paper The power from that insert will then sprinkle the soil. The inflated gummy, especially bentonite, in powder form or granular substance, in the required amount, is applied onto the structure, and the coated sachet material is passed through the needle stab machine. Blistering clay The gain is then thrust into the spinning structure And the whole structure All of them are bonded together by means of a needle insertion and then the free or both sides of the composite are combined. With water and finally dry 4. The method that holds the rights in any of the claims. From claims 1 to 3, which are unique in that there are Using a knitting and / or sewing method instead of stabbing a needle. 5. The method of holding the rights in any of the claims. From claims 1 to 4, which are unique at A backing layer that consists of paper after it has been moistened. Completely or completely removed from one side of The exposed part, which is then further moistened and dried. 6. The method of holding the rights in any of the claims. From claims 1 to 5, which are unique, have Drying operation using infrared heating Or made in a kiln or in a hot air tunnel 7. Means as held in any of the claims From claims 1 to 6, which are unique, have The drying operation, but only until bentonite has A certain amount of moisture remains
