Description

The utility model relates to insulating building materials and is mainly used for hydro- and vapor barrier of roofs, walls and ceilings.

Known roll insulation material, which is a polypropylene-based fabric, made with the possibility of bonding during installation of its adjacent panels using a longitudinal adhesive strip of hot-melt adhesive based on synthetic rubber, applied along one edge of the fabric, closed with a removable protective tape (RU 173969 U1).

Also known is a roll of insulating material, which is a polypropylene-based fabric made with the possibility of bonding during installation of its adjacent panels using an adhesive strip of hot-melt adhesive based on synthetic rubber, closed with a removable protective tape applied along one edge of the fabric on its outer side and along the other edge of the canvas on its inner side (RU 189413 U1).

The hot-melt adhesives used for applying adhesive strips based on synthetic rubbers are usually yellow in the initial state (in bars), and only a yellowish tint in a thin layer (in the form of an applied adhesive strip). The adhesive strip, which has a yellowish tint, both covered with a removable protective tape and free of it, is not visible on the canvas due to insufficient brightness, especially in low light conditions, which always accompanies the installation of insulating material in a building under construction.

Closest to the proposed utility model is a well-known rolled insulating material, which is a polypropylene-based fabric made with the possibility of bonding during installation of its adjacent panels using a longitudinal adhesive strip of hot-melt adhesive based on synthetic rubber coated on the fabric, closed with a removable protective tape (RU 158448 U1 - prototype).

The removable protective tape is made of a lavsan film with a silver metallized coating so that, as indicated in RU 158448 U1, the initially transparent lavsan film is visible on the canvas.

The disadvantage of this known roll of insulating material is due to the fact that during installation the painted protective tape after fixing the first (lower) panel is completely removed from it and the adhesive strip remains open. Moreover, if Adtek (Zakley) 902 adhesive used in RU 158448 U1 in the initial state (bars) is amber, then in a thin layer on the adhesive strip it is transparent and almost colorless, and therefore it is possible to distinguish the adhesive strip only by glare, looking at her at an angle. In practice, the process is complicated by the fact that in the building under construction, the installation of insulating material is carried out, as a rule, in low light conditions.

The technical problem, the solution of which is provided when using the proposed utility model, is the elimination of this drawback.

The technical result provided by the proposed utility model and objectively manifested when it is used is to increase the productivity of the installation process of rolled insulating material.

The specified technical result is achieved by the fact that in the roll of insulating material, which is a polypropylene-based fabric, made with the possibility of fastening during installation of its adjacent panels using a longitudinal adhesive strip of hot-melt adhesive based on synthetic rubber, coated on a canvas, closed with a removable protective tape, on the surface of the canvas under the adhesive strip is marked with a marking in the form of a strip having a color different from the color of the canvas, and the removable protective tape is painted in excellent color from the color of the canvas.

The specified adhesive strip can be applied along one edge of the canvas. However, in particular, the specified technical result is manifested in the case when the adhesive strip is applied along one edge of the canvas on its outer side and along the other edge of the canvas on its inner side. In this case, the adhesive strips of adjacent panels, highlighted by the specified signal marking, allow you to quickly make accurate overlap them on top of each other and their most durable connection on the type of "glue on glue".

Improving the performance of the installation process of insulating material according to the proposed utility model is achieved due to the following.

Signal marking - the painted surface of the canvas under the adhesive strip is a strip having a color different from the color of the canvas, which is sufficient for the installer to visually perceive the signal marking under a thin layer of transparent glue and a layer of removable protective tape painted in a color different from the color of the canvas. This circumstance allows the installer not to waste time identifying not only the outer side of the insulating material, but also the location of the adhesive strip on the surface of the canvas, which accelerates the installation process, i.e., increases its productivity.

Signal marking can be applied in flexographic, silk-screen or digital printing, preferably with water-based inks, which is technologically advanced and economical.

As a polypropylene-based polymer web, woven polypropylene can be used (for example, https://protkani.com/tkani/polipropilenovaya-tkan.html and http://pppe.ru/catalog/polipropilenovyie-izdeliya/laminirovannaya-polipropilenovaya-tkan ) and non-woven materials (for example, http://www.snabika-rf.ru/laminirovannyi_spunbond). Moreover, for the waterproofing of roofs, walls and ceilings, the above woven materials can be used (for example: https://protkani.com/tkani/polipropilenovaya-tkan.html and http://pppe.ru/catalog/polipropilenovyie-izdeliya/laminirovannaya -polipropilenovaya-tkan), for vapor barrier - the above non-woven materials (for example: http://www.snabika-rf.ru/laminirovannyi_spunbond).

The adhesive strip is made of hot-melt adhesive based on synthetic rubber, which refers to adhesives with residual stickiness. Such adhesives do not become solid after being applied to the material. An adhesive bond is formed after squeezing the layers of material between which there is an adhesive layer, therefore such adhesives are called PSA ("Pressure Sensitive Adhesive" - pressure sensitive adhesive). Hot-melt adhesive based on synthetic rubber does not contain solvents, which ensures the safety of its use. To produce adhesive strips in a roll of insulating material according to the proposed utility model, any hot-melt adhesive on the basis of synthetic rubber of the appropriate purpose, for example Ergotek 430 series (http://ergotek.ru/products/product.php?id = 23), Adtek (Zakley) 902 (http://adtek.ru/catalog/termoplavkiy-kley/adtek-902/) and others.

To ensure visibility of the location of the adhesive strip on the canvas at the beginning of installation, the removable protective tape can be made of any transparent or painted release material of the appropriate purpose (see, for example, http://likk.ru/silikonizirovannye_materialy/), preferably made of silicone lavsan ( polyethylene terephthalate) or biaxially oriented polypropylene film (http://likk.ru/silikonizirovannye_materialy/plenki/).

The manufacturing process of the rolled material according to the proposed utility model is carried out on the polypropylene web drawing line, which is equipped with glue heads of the glue apparatus. The glue head is installed so that glue is applied to the signal strip made on the canvas. Directly behind the glue head of the glue apparatus through the clamping shafts on the glue strip set the feed unit of the removable protective tape.

Example 1

In the manner described above, a rolled waterproofing material is made, which is a polypropylene-based polymeric fabric - a woven material (http://pppe.ru/catalog/podkrovelnaya-gidroizolyacziya) of gray color, along one edge of which is on the outside and along the other edge on the inside applied along one longitudinal strip of hot-melt adhesive based on synthetic rubber Ergotak 430. The adhesive was applied to the signal marking on the canvas, made in the form of a green-colored strip. The width of the signal marking strip and the adhesive strip is the same and is 35 mm. The adhesive strip is closed with a removable protective tape made of a transparent siliconeized biaxially oriented polypropylene film. Each of these strips of hot-melt adhesive is located at a distance of 100 mm from the corresponding edge of the polymer web. When mounting adjacent panels from this roll material, a glue on glue joint is formed.

Example 2

In the manner described above, a rolled vapor barrier material is made, which is a polypropylene-based polymeric fabric - a non-woven spunbond material (http://www.snabika-rf.ru/laminirovannyi_spunbond) of gray color, along one edge of which a longitudinal strip of hot-melt adhesive based on synthetic rubber Adtek (Zakley) 902, covered with a removable protective tape made of silicone green dacron film. Glue was applied to the signal marking on the canvas, made in the form of a strip painted in red. The width of the signal marking strip and the adhesive strip is the same and is 35 mm. The adhesive strip of hot-melt adhesive is located at a distance of 60 mm from the edge of the polymer web.

Example 3

By the method described above, a rolled waterproofing material is made, which differs from the waterproofing material in Example 1 only by the absence of a signal strip on the canvas and the fact that the removable protective tape has an external metallized silver coating.

Example 4

By the method described above, a rolled vapor barrier material is made that differs from the vapor barrier material in Example 2 only by the absence of a signal strip on the canvas and the fact that the removable protective tape is made of a transparent siliconized dacron film.

To conduct comparative tests for 5 hours, the installation of subroofing insulating layers was carried out using each of the rolled insulating materials according to examples 1-4 separately in the same conditions under natural light.

Installation of an insulating layer of rolled insulating material involves rolling it onto a structure.

The installation of the insulating layer of coiled insulating material according to examples 1 and 3 is carried out from the bottom up, placing the panels of coiled insulating material horizontally so that the adhesive strip applied to the outside of the polymer web is located along the upper edge of the web. The first roll of insulating material is attached to the insulated surface using an adhesive strip freed from a removable protective tape applied to the inner surface of the polymer web (the “lower” adhesive strip). The second panel of the roll of insulating material is lapped to the first, forming a glue-to-glue joint by combining the adhesive strip of the first panel and the adhesive strip of the second panel, released from the removable protective tape, and rolling with a rubber roller. For fastening the third panel of roll insulation material, the "upper" adhesive strip of the second panel, located on its outer side, is combined with the "lower" adhesive strip of the third panel, located on its inner surface. Further, the process of forming the insulating layer is carried out in the same way.

The installation of the insulating layer of insulating material according to examples 2 and 4 is carried out by fixing the lower panel to the frame elements. The lower panel is positioned so that the adhesive strip runs horizontally along its upper side. After that, the upper panel is overlapped, the removable protective tape of the lower panel is completely removed from under it and the place of gluing is rolled with a rubber roller.

According to the test results, the following is established.

Due to the fact that the roll insulation materials according to examples 1 and 2 have adhesive strips that are clearly visible due to their highlighting with signal strips (signal markings) of sufficient brightness applied to the canvas, the installation process is simplified and accelerated, as a result, the amount of work performed with the roll insulation the material in example 1 exceeded the amount of work done with the same material in the example 3 by 28%, and the amount of work done with the material in the example 2 exceeded the amount of work done with the same material according to example 4 to 26%. It was additionally established that the underlay layers of materials of examples 1 and 2 have no defects, and the underlay layers of materials of examples 3 and 4 have local defects in the connecting "seams" between adjacent panels.
