Russian Federation Patent RU2197582
METHOD FOR PRODUCING ROLLS waterproofing material
Name of the inventor: Vladimir Koshkin
The name of the patentee: Vladimir Koshkin
Address for correspondence: 420110, resp.Tatarstan, Kazan, and / I 2, pat.pov. N.S.Gaynutdinovoy, Identification No 256
Starting date of the patent: 2001.03.13
The invention relates to the field of construction and is intended for the production of roofing and waterproofing materials. The technical result of the invention is to simplify the method of production of roofing waterproofing materials. A method of producing a waterproofing material web comprises layering on the pallet setup layers, in particular a waterproofing material, wherein the waterproofing material is a mastic based on cold aqueous emulsion. The process is carried out at a temperature of +5 o C, followed by exposure to dry completely roll waterproofing material.
DESCRIPTION OF THE INVENTION
The invention relates to the field of construction materials and are designed for the production of roofing and waterproofing materials.
Known methods of producing roofing materials bituminous compositions, comprising a continuous movement, the pallet conveyor belt, onto which a layered protective layer is a mineral powder such as talc, a layer of plastic material - a waterproofing composition, bitumen melt base layer - fiber or fabric material, cardboard or other heat-resistant base layer of melted bitumen as the impregnating material, coating waterproofing layer of bituminous composition and, if necessary, the last of the spreading layer or film (see., eg, polymer industry, soft roofing and thermal insulation materials, series 6. Overview. Issue 1. Production of roll bituminous materials -. M .: VNIIESM, 1987, s.36-60 [1] Description of the invention to the inventor's certificate SU 1488415 A1 [2]). These methods have the disadvantage that they use high-melting bituminous compositions that require heating them to a high temperature of the order of 150-180 o C, which complicates the process of production of rolled materials, limits the choice of the substrate material that can withstand the high processing temperatures, places high demands on safety equipment and facilities, employees, causing a large power consumption. The method [2] is the closest analogue.
The objectives of the invention, the method is a significant simplification of the mode of production of roofing waterproofing materials, expanding the choice of materials through the use of foundations as a waterproofing and impregnating layer of cold bitumen emulsion mastics.
This problem is solved in the process for roofing and waterproofing materials, which assumes layering on the pallet setup insulating particulate material such as talc, waterproofing composition (mastic), foundations, as which can be used fiberglass, foil, polymer-fiber and other materials (or the web material is formed without the base), waterproofing layer on the other side of the base. Waterproofing layers are formed from cold mastic, is an aqueous emulsion of bitumen, for example, cold asphalt mastic (SN Popchenko Cold asphalt waterproofing -.. L .: Stroyizdat, Leningrad Dep, 1977, [3], p.131, Description. to AS N 1801973, C 08 L 95/00. Official Gazette, N 10, 1993 [4], and others.). When using this stand, which is a tray with low sides, onto which the layers of components with dimensions matching the desired size of the roofing material, e.g., length 10 m, width of 1 m, i.e. Roll size, convenient for the production of roofing. The pallet has a lattice, mesh or perforated surface, water permeable, a mastic in the formation of a panel of the web material. In addition to not leave part of the bitumen through the pan on it before applying layers of fabric laid a rare type of canvas, impermeable bitumen emulsion, but to pass water. Exposure of the material layers should be formed at a temperature not lower than +5 o C for several hours (overnight) to remove water from the bottom of mastic, under the action of gravity, and the top - by evaporation and obtain a cheap, easy to manufacture and operation of the roll waterproofing material, especially roofing.
A method implemented in proposed device layering manually or via-capacity hopper with a slot opening width of 5.10 mm on a perforated tray installation, ready made type rare cloth tarps, burlap, etc., and these materials can withstand such a layer system at temperature above +5 o C, for example at room temperature until completely dry material. In practice, this time depends on the temperature and humidity room where you work on, and is approximately one day. During exposure the water flows down, and evaporates and leaving a layer of smooth dried particulate bitumen. The upper layer may be formed as the bottom of particulate mineral material. A grit hopper or mastic can move relative to the pallet trolley, pouring a thin paste, and 10 mm, a layer across the area of the pallet. If necessary, the layers can be applied by hand trowel to align either automatically setting the movable stopper above the tray thickness. After drying, the resulting material is rolled and shipped to the consumer.
This technology is difficult to realize on a moving belt-conveyor, as in [2], as the water from the mastic leaves slowly enough, and for a finite length of tape to had time to form panel of the web material before it is completely dry, would have to a conveyor equipped with additional devices for pumping and / or drying of water, disrupting the natural drying conditions and deteriorating the quality of the final product.
The proposed roll material manufacturing technology is simple, requires low power and simple malometalloemkoe simple equipment that is safe and will be used in production.
CLAIM
A method of producing a waterproofing material web comprising layers of layering on the pallet setup, in particular a waterproofing material, characterized in that the waterproofing material is a mastic based on cold aqueous emulsion of bitumen, the process is carried out at temperatures above +5 o C, followed by aging roll to complete drying of the waterproofing material.
