Description

[Detailed description of the invention]

The present invention relates to a method for installing a rug on a floor surface of a rug-base assembly, and more particularly, the present invention relates to a rug-base assembly comprising an elastomer base applied to the floor surface and a rug such as a mat on the base. This invention relates to a method for easily forming a rug-base assembly by on-site construction, which does not shift or peel during use, allows easy replacement of the rug, and allows easy removal of the base when necessary. . From the viewpoint of hygiene, it is preferable to periodically clean mats, carpets, and other mats placed on the floor. There are two types of rugs: those fixed to the floor and those spread removably on the floor.In the former type, the fixed rug must be washed on the spot. Not,
There are problems in that the cost is quite high and it is difficult to clean frequently. Also, as the latter type, there is a so-called dust control mat (dusting mat).
For example, they are placed at the entrances of coffee shops, cafeterias, banks, hotels, offices, etc. to remove dust adhering to the soles of shoes and prevent dust from entering indoors. For the mat after this, it is necessary to prevent the mat from shifting or peeling off when walking on it, and for this purpose, thick backing made of synthetic rubber or elastomer resin is applied to the back side of the mat. , one in which an elastomer base and a mat are integrated, or one in which a frame-shaped base is manufactured from the synthetic rubber or elastomer resin and the base and mat are removably engaged with so-called Velcro fasteners, etc. are used. has been done. The latter type of base/mat assembly has the advantage that only the mat can be removed and replaced and cleaned, but since the base must be molded, the shape and dimensions cannot be fixed. It has the disadvantage of being limited to certain things. In addition, the former integrated mat with base has the advantage that it can be cut into any shape and size.
Since the washing must be carried out with the base attached, the washing load is significantly increased compared to when the mat is used alone.The base reduces water permeability, resulting in low dewatering efficiency.Furthermore, dewatering is poor, resulting in shorter drying times. A problem arises in that the drying cost increases significantly. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a method for constructing a removable rug and elastomeric base assembly in any shape and size on a floor surface. Another object of the present invention is to comprise an elastomer base applied to a floor surface and a rug such as a mat on the base, and when the rug is used, the rug is effectively fixed without shifting or peeling. To provide a rug-base assembly in which only the rug can be easily replaced when soiled, and the base can be easily peeled off from the floor surface when necessary, and a method for easily forming the assembly by on-site construction. There is something to do. According to the present invention, a removable primer is applied to the floor surface to be constructed, a liquid resin that becomes an elastomer upon curing is poured onto the primer layer, and the fiber loops on the back side of the rug are secured to the surface of the liquid resin layer. A removable locking element is embedded in the element, the liquid resin is cured into an elastomer, and the 90°C peel force between the cured elastomer layer and the floor surface is set in the range of 30 to 1000 g/2.5 cm using the peelable primer. Provided is a method for installing a rug on a floor surface that is characterized by being maintained. The invention will be explained in detail below with reference to the accompanying drawings. Part 1 for explaining the steps of the construction method of the present invention
In Figures A to 1-E, first, the floor surface 1 to be constructed is cleaned by a cleaning method known per se depending on the material of the floor (Figure 1-A). Next, in FIG. 1-B, a layer 2 of a removable primer, which will be described in detail later, is formed on a predetermined area of the cleaned floor surface 1. The floor surface on which this peelable primer layer 2 is formed is divided by a frame 3 as shown in FIG. Pour to the specified thickness. continue,
1-D, a locking element (for example a male Velcro fastener), generally designated 5, is embedded in the surface of the liquid resin layer 4 while it is in an uncured state. This locking element 5 is composed of a base fabric portion 6 and a hook-shaped or mushroom-shaped locking piece 7 set into the base fabric portion 6. Locking element 5
The resin layer 4 is cured with the 1st-
Convert it into an elastomer base 4a shown in Figure E,
Remove frame 3. Finally, elastomer base 4a
A rug 8 is placed on top of the rug 8, and a fiber loop element 9 sewn to the back side of the rug 8 is engaged with a locking element 5 fixed to the base 4a, thereby locking the rug 8 onto the base 4a. The rug 8 may consist of a base fabric 10, a fiber pile 11 tufted to the base fabric 10, and a packing layer (not shown) for fixing the pile applied to the back side of the base fabric 10. In the mat base assembly according to the method of the present invention, the elastomer base 4a is bonded to the floor surface 1 via the releasable primer layer 2, and the elastomer base 4a and the rug 8 are locked via the locking elements 5, 9. It has the structural feature of being That is, in the rug-base assembly according to the present invention, the base is made of a rubber-elastic and flexible elastomer, and this base is bonded to the floor surface via the releasable primer layer 2, and the bonding force is as described above. Since the locking force is larger than that of the locking elements 5 and 9, the position of the rug 8 is effectively prevented from shifting or the rug 8 is peeled off during normal use. 9
There is an advantage that the base 4A is stably held on the floor surface 1 without being peeled off from the floor surface 1 even when the base 4A is peeled off between the floor surface 1 and the floor surface 1. In addition, when the rug 8 becomes dirty due to adsorption and retention of dust, etc., only the lightweight rug 8, which is made mostly of fibers, can be removed from the base and washed easily without the drawbacks mentioned above. Can be easily replaced with a rug. Furthermore, when it is no longer necessary to lay the rug 8 on the floor surface 1, or when another flooring material is to be laid on the floor surface 1,
Since the elastomer base 4a is bonded to the floor surface 1 via the releasable primer 2, it can be easily removed by hand at the interface between the releasable primer layer 2 and the floor surface 1 without damaging the floor surface 1. It can be performed. Moreover, the elastomer base under the rug has the advantage of providing adequate cushioning for people walking on the rug. Furthermore, the present invention has the advantage that a rug of any shape and size can be applied to any location on a floor surface easily in the form of a rug-base assembly by on-site installation. The present invention can be applied to any floor surface, such as a concrete floor, a mortar coated floor, a mortar floor mixed with synthetic rubber latex, a sticky floor made of painted or unpainted wood, a vinyl chloride resin tile floor, a vinyl chloride resin linoleum floor, an epoxy resin floor, or a floor coated with mortar. It can be widely applied to floors painted with hard urethane resin, ceramic tiles, artificial marble, etc. As a removable primer, it can be used to
90℃ peeling force 30 to 1000g/2.5mm, especially 70 to 300
A removable primer having a range of g/2.5 cm is preferably used. That is, a removable primer with a peeling force smaller than the above range is undesirable because the base tends to peel off from the floor surface when the rug is used or when the rug is peeled off from the base, and a peeling force larger than the above range is undesirable. Sometimes, it becomes difficult to remove the base from the floor surface, or the floor surface and the base tend to be damaged when the base is peeled off. The releasable primer used in the present invention is a primer vehicle that has a balance between releasability and adhesion as described above, and suitable examples thereof include, but are not limited to, the following. (1) Copolymers containing long-chain alkyl group-containing monomer components: copolymers of long-chain alkyl acrylates, copolymers of long-chain alkyl acrylamides, copolymers of long-chain alkyl esters or amides of maleic acid, and others such as itaconic acid. Copolymers of long-chain alkyl esters of polybasic unsaturated carboxylic acids, copolymers of long-chain alkyl allyl esters, copolymers of long-chain alkyl vinyl ethers, copolymers of long-chain olefins, polyureas or polyurethanes linked by polyisocyanates containing long-chain alkylene groups, Polyamide or polyimide containing long chain alkylene groups. (2) Long-chain alkyl groups have been introduced into the functional groups of natural or synthetic polymers: long-chain alkyl ester polymers, long-chain alkyl carbamate polymers, long-chain alkyl amidation or urea polymers. (3) Perfluoroalkyl-containing polymers: Polymers or copolymers of perfluoroalkyl-containing vinyl monomers, methylolates of perfluoroalkyl-containing triazines or their initial condensates, chromium compounds of perfluoroalkyl-containing fat-blocking acids. , perfluoroalkyl carbamate. (4) Silicone derivatives. (5) Chromium-containing compounds (6) Combined use of long-chain alkyl compounds and resins. To apply the above-mentioned releasable primer to the floor surface, first clean the floor surface, apply the above-mentioned releasable primer to the floor surface in the form of a solution or dispersion, and dry if necessary to apply the primer layer to the floor surface. to form.
If the floor surface to which the removable primer is applied is permeable to a solution or dispersion, seal it with a saw or the like or apply an undercoat with any resin before applying the removable primer. may be advantageous. Solvents for peelable primers include aromatic solvents such as toluene and xylene; ketone solvents such as acetone, methyl ethyl ketone, methyl isobutyl ketone, and cyclohexanone; ether solvents such as tetrahydrofuran and dioxane; isopropyl alcohol, ethanol, and diascent alcohol. Alcoholic solvents such as methyl cellosolve,
Cellosolve solvents such as ethyl cellosolve and butyl cellosolve; Ester solvents such as ethyl acetate and butyl acetate; N,N-dimethylformamide, N,
Amide solvents such as N-dimethylacetamide; chlorinated hydrocarbon solvents such as carbon tetrachloride and methylene chloride are used alone or in combination of two or more. Instead of using the strippable primer described above in the form of a solution, it is also possible to use it in the form of an aqueous emulsion or latex. The above-mentioned primer coating solution is generally used at a concentration of 5 to 60% by weight of non-volatile matter, particularly 20 to 40% by weight, and this solution contains additives known per se, such as colorants and leveling agents. , thickeners, thinners, antifoaming agents, fillers, binders, etc. can be blended. In particular, a resin binder other than the above-mentioned releasable primer component may be added to this solution to impart releasability through bleed-out. The added resin binder is
It also has the effect of preventing the removable primer from seeping into the floor surface. Coating to the floor surface can be done by any means such as brush coating, roller coating, spray coating, electrostatic coating, etc. The coating amount may theoretically be a monomolecular film and is not particularly limited, but generally Generally speaking, the non-volatile content is 1 to 100 g/m ² , especially 15 to 35 g/m ²
It is advantageous to apply in an amount such that The resin used may be any supporting resin that becomes an elastomer upon curing, and polyurethane resin is particularly advantageously used in terms of ease of construction. Useful polyurethane is a two-component type consisting of a hydroxyl component and an isocyanate component.As the hydroxyl component, polyester polyols, polyether polyols, ethylene oxide adducts to polyhydric alcohols, etc. are used, and as the isocyanate component, , polyisocyanates and isocyanate-terminated prepolymers are used. During construction, these two liquids are mixed, a catalyst such as an amine is added, and the mixture is applied to a floor surface that has been coated with a removable primer.
When applying this elastomer resin, it is also possible to mechanically foam the resin by mechanically mixing in a gas such as air or nitrogen. Furthermore, auxiliary agents such as colorants, fillers, reinforcing agents, and extenders can be added to this resin composition according to known formulations. In the present invention, the liquid resin composition used is preferably transparent or translucent. That is, the second
As shown in the figure, when installing on the floor surface, marks 13 indicating the embedded position of the locking elements are placed at defined positions of the area 12 to be covered, generally at the four corners.
Perform steps a, 13b, 13c, and 13d. When the liquid resin layer 4 is transparent or translucent, the position where the locking element is embedded can be easily confirmed through this layer, and the locking element can be accurately fixed. In the present invention, the above-mentioned polyurethane is most suitable as the liquid resin for forming the elastomer, although it has the disadvantage of requiring heat curing.
Plastisol compositions of vinyl chloride resin can also be used. Furthermore, latexes such as natural rubber, NBR, SBR, polybutadiene, butyl rubber, and chloroprene can also be used, and these may be unfoamed or foamed. Thickness is 0.2
A thickness in the range of 1 to 10 mm, particularly 1 to 5 mm, is effective in preventing the rug from curling up or shrinking during use. The present invention is particularly advantageous for installing rugs in areas where the rugs are extremely dirty and require frequent cleaning, such as entrances, room entrances, toilets, bathrooms, and shelters. It has the advantage that the rug can be constructed on-site. The invention is illustrated in the following examples. Example 1 Dirt on the concrete floor was wiped off with a tightly wrung wet rag, and Pearoyl 81 (manufactured by Ichisha Yushi Kogyo Co., Ltd., trade name, 30% toluene solution of "long chain alkylamidated polymer") was removed. As a primer, 50g ^per square meter was applied with a brush. After 5 minutes, confirm that the removable primer is dry, and then apply commercially available two-component urethane flooring materials, namely Takenate F-135 (isocyanate component) and Takerac PC5300 (manufactured by Takeda Pharmaceutical Co., Ltd.). 90 cm long and 75 cm wide.
cm, and poured onto the floor surface to a thickness of 0.2 mm,
Prior to curing of this resin, locking elements with hooks (male Velcro fasteners) were embedded in the four corners of the top surface and left at room temperature to harden the resin and adhere to the floor surface. The adhesive strength between the floor material (base) and the concrete floor surface after curing was 70 g/2.5 cm at 90° peeling. Tufted crimped nylon multifilament into polyester plain woven fabric (cage 5/32, stitched)
6.4, pile height 9 mm, basis weight 880 g/m), locking elements with fiber loops ( A mat to which Velcro fasteners (female) were sewn was prepared, and the mat was fixed by engaging with a locking element with a hook on the flooring material. The locking element used to temporarily lock the mat and flooring had a peel strength of 30 g/2.5 cm in another 90° peel test, and after 100 repetitions of mat engagement and peeling. Also, no peeling occurred between the urethane flooring material and the concrete floor surface. Furthermore, when this pine covered area was subjected to an actual walking test for about one month, there was no peeling or misalignment between the urethane flooring material and the concrete floor surface. After one month had passed, the adhesive strength between the urethane flooring material and the concrete floor surface was 90 g/2.5cm, and it was possible to peel off the entire surface of the flooring material by pulling it by hand. For comparison, urethane flooring was applied directly to the floor without applying a removable primer and cured in the same manner as in the example. The difference between the urethane flooring and concrete floor after curing was It was extremely difficult to remove it manually, and when we tried to remove it forcibly, the concrete floor surface was destroyed. Example 2 After cleaning each floor shown in Table 1 below,
The peelable primer shown in the table was applied with a brush and air-dried. However, Sample 3 was heat-treated at 100°C for 1 minute, and Sample 4 was heat-treated at 150°C for 1 minute. Urethane resin (Takenate F-135, Takerac PC-5300) is applied to each floor surface treated with a peelable primer.
(1:1 weight ratio mixture) of 70mm x 200mm x 5mm
It was poured into a mold to the size of , and after curing for 3 days, a 25 mm wide cut was made in the cured urethane resin to prepare a sample. For each sample, Shimadzu Autograph P-
A 90° peel test was conducted using Model 100 at a peel rate of 300 mm/min. The results obtained are shown in Table 1 below. Furthermore, the tensile strength of urethane resin is 15000g/5mm.
It was 25mm.
