Известны способы нанесени на твердое основание, например черепицу, покрывающих слоев или листов.Methods are known for applying to a solid base, such as tiles, covering layers or sheets.
Покрывающие слои имеют основание из битума и укрепл ютс синтетическими нит ми, предварительно обработанными веществами, улучшающими их сцепление с битумом.The covering layers have a base of bitumen and are reinforced with synthetic yarns, pretreated with substances that improve their adhesion to bitumen.
Цель изобретени - расширить сырьевую базу.The purpose of the invention is to expand the resource base.
Дл этого в качестве армирующих волокон используют нити из синтетических продуктов линейной поликонденсации, обработанные раствором буроугольной смолы или суспензией этой смолы .в воде; кроме того, используют нити из полиэтилентерефталата.For this, yarns of synthetic linear polycondensation products treated with a solution of a coal tar or a suspension of this resin in water are used as reinforcing fibers; In addition, polyethylene terephthalate filaments are used.
Пример. Из смеси песка, имеющего модуль товинЫ 2,0, в количестве 43,5%, вычисленном из чистой минеральной смеси, низкосортного наполнител с тониной 200 меш (4,5%), гальки с размером частиц не более 16 мм (50%) и битума с величиной проникани 80,5 и точкой разм гчени 46,9°С в количестве 4,5%, основанном н.а минеральной смеси, черепица, размером 30X30 см и весом 3200 г превращаетс в прессованную черепицу .Example. From a mixture of sand having a modulus of toviny 2.0, in an amount of 43.5%, calculated from pure mineral mixture, low-grade filler with a fineness of 200 mesh (4.5%), pebbles with a particle size of not more than 16 mm (50%) and bitumen with a penetration rate of 80.5 and a softening point of 46.9 ° C in an amount of 4.5%, based on mineral mixture, the tile, measuring 30 x 30 cm and weighing 3200 g, turns into extruded tile.
Прессование осуществл етс при 135±5°С. После прессовани черепицу охлаждают до 10°С и добавл ют 27 г эмульсии бельгийского асфальта, котора содержит 49% битума. После растворени и выдерживани эмульсииPressing is carried out at 135 ± 5 ° C. After pressing, the tile is cooled to 10 ° C and 27 g of Belgian asphalt emulsion, which contains 49% bitumen, is added. After dissolving and holding the emulsion
на черепицу накладывают плетеную ткань, имеющую полиэтилентерефталатную основу. Эта ткань показывает 4 нити в основе и 4 нити в утке на 1 см в продольном плетении.on the tile impose a woven fabric having a polyethylene terephthalate base. This fabric features 4 yarns at the base and 4 yarns in weft 1 cm longitudinally weaving.
Ткань загружают буроугольной смолой с точкой затвердевани 75-76°С, кислотное число между 30 и 40 и число омылени между 55 и 65, в количестве 35% от веса ткани.The tissue is loaded with a brown coal resin with a hardening point of 75-76 ° C, an acid number between 30 and 40, and a saponification number between 55 and 65, in an amount of 35% by weight of the fabric.
Дл этого пропускают ткань через раствор одной части буроугольной смолы в двух част х этилацетата при температуре около 35°С. Пропитанную ткань сушат в две стадии: перва стади - воздухом при 20°С, втора стади - досущивают при 60°С. Высушенную ткань затем охлаждают до комнатной температуры.For this, the fabric is passed through a solution of one part of a brown coal tar in two parts of ethyl acetate at a temperature of about 35 ° C. The impregnated fabric is dried in two stages: the first stage is air at 20 ° C, the second stage is dried at 60 ° C. The dried fabric is then cooled to room temperature.
