[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curing member used to prevent the floor from being stained when a house is constructed. More specifically, the present invention can prevent moisture from penetrating into the floor. The present invention relates to a curing member that is less likely to be displaced or damaged, and that is not slippery even when wet.

[0002]

2. Description of the Related Art Conventionally, when a house or the like is constructed, the floor surface may be soiled by soil or rain attached to the soles of the builder, or may be deformed or discolored. For this reason, it is common practice to use a cardboard card, a plastic film, or the like as a curing member and temporarily fix it with adhesive tape on all sides to cover the floor surface.

However, in the case described above, it is inevitable that moisture infiltrates between the floor surface and the curing member due to rain or the like, and a gap may occur between the floor surface and the curing member, or the curing member may not move. The floor is often not sufficiently prevented from being stained, deformed or discolored due to damage. In addition, the floor or the surface of the curing member is usually blacked out in advance to facilitate interior construction. However, if the curing member becomes dirty or misaligned, the blacked out part disappears or shifts, and the blacking out starts. Becomes useless. Furthermore, especially when the curing member is wet by rain or the like,
When walking on the curing member, it is slippery and there is a risk of falling.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, to prevent moisture from penetrating into the floor, and to reduce the occurrence of displacement or damage to the floor, and furthermore, ,
An object of the present invention is to provide a curing member which is not slippery even when wet.

[0005]

Means for Solving the Problems The present inventor has made it possible to prevent the infiltration of moisture into the floor surface, the displacement and breakage of the curing member, and the like, by bringing the curing member into close contact with the floor surface with an adhesive. They found that slippage was prevented by forming irregularities on the upper surface, and completed the present invention.

[0006] The floor curing member of the present invention has a pressure-sensitive adhesive layer formed on one surface of a base material, and irregularities formed on a non-adhesive surface of the base material. A non-adhesive surface of the substrate having a coefficient of static friction of at least wet 1.05, dry 1.05, and a center line average roughness Ra of the non-adhesive surface of 1 to 35 μm.

Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is a schematic sectional view of a floor curing member showing one embodiment of the present invention. In the figure, C is a floor curing member, which comprises a base material 1 and an adhesive layer 2.

As the substrate 1, any paper, plastic film or the like which is usually used as a floor curing member can be used. In the present invention, a plastic film having excellent water resistance and mechanical strength can be used. Particularly preferred. Examples of the plastic film include a polyethylene film, a polyvinyl chloride film, a polypropylene film and the like.

Although the thickness of the substrate 1 is not particularly limited, it is usually about 60 to 150 μm.

In the present invention, the non-adhesive surface 1b of the substrate 1
As a result, irregularities 11 are formed. The unevenness 11 is for preventing slippage on the surface of the floor curing member C. Further, the irregularities 11 also have an antiglare effect of preventing direct reflection of sunlight, in addition to the above-described prevention of slippage, particularly when the substrate 1 is made of a plastic film.

The irregularities 11 are formed so that the static friction coefficient of the non-adhesive surface 1b of the substrate 1 is at least wet 1.05 and dry 1.05, preferably at least wet 1.1 and dry 1.1. desirable. The static friction coefficient of the non-adhesive surface 1b of the base material 1 is wet 1.05 or more, dry
If it is 1.05 or more, a sufficient anti-slip effect can be obtained. In the present specification, “wet” refers to the substrate 1
Refers to a state in which 5 g / 100 cm ² of tap water is sprayed on the non-adhesive surface 1b.
This refers to a state in which no water is present on the non-adhesive surface 1b under a 5% RH atmosphere. Further, the coefficient of static friction of the non-adhesive surface 1b in each state is determined by applying a load of 1 kg (the contact surface is made of chloroprene rubber) to the non-adhesive surface 1b,
It is a numerical value measured when pulling at a speed of / min.

To set the coefficient of static friction of the non-adhesive surface 1b of the substrate 1 as described above, for example,
b has a center line average roughness Ra of 1 to 35 μm, preferably 3
What is necessary is just to form the unevenness 11 so as to be 15 μm. When the Ra is less than 1 μm, the frictional resistance of the non-adhesive surface 1b becomes small.
b, the contact area on the surface becomes smaller, the frictional resistance becomes smaller, and the unevenness is transferred to the pressure-sensitive adhesive layer 2, and the bonding area when the curing member C is bonded to the floor becomes smaller. This is not preferable because the force is reduced, and further, water infiltrates from the wrap portion (the portion where the curing member C is overlapped) and the floor member is likely to be deformed or discolored. The center line average roughness Ra of the non-adhesive surface 1b of the substrate 1 was measured using a surfcom 554A (trade name, manufactured by Tokyo Seimitsu Co., Ltd.) at a measurement distance of 4 mm and cut off.
It is a numerical value measured at 0.8 mm at a measuring speed of 0.3 m / min.

The shape of the irregularities 11 is not particularly limited.
Examples of the method for forming the irregularities 11 include a method such as pressure bonding using an irregular roll.

The pressure-sensitive adhesive layer 2 is made of a rubber such as a conventionally known natural rubber, a styrene-butadiene rubber, a polyisobutylene rubber, a polymer of isoprene rubber, or a copolymer containing 2-ethylhexyl acrylate or butyl acrylate as a main monomer. Acrylic-based pressure-sensitive adhesives are used. To this adhesive, a tackifying resin such as a phenol resin, a rosin, a pinene resin, a petroleum resin, a styrene resin, and a chroman resin is added, and further, if necessary, a softener, a filler, an ultraviolet absorber, an antioxidant. In addition, various materials such as a cross-linking agent and the like may be used without departing from the scope of the present invention.

Although the thickness of the pressure-sensitive adhesive layer 2 is not particularly limited, it is suitably about 15 to 25 μm.

The adhesive strength of the pressure-sensitive adhesive layer 2 is 0.5
It is preferably set to be about 4.0 N / 20 mm. When the adhesive strength of the adhesive layer 2 is 0.5 N / 20 mm or more, the curing member C and the floor surface can be sufficiently adhered to each other.
When it is 0 N / 20 mm or less, the curing member C can be easily peeled off from the floor surface after the construction of the house. The adhesive strength of the pressure-sensitive adhesive layer 2 is adjusted by the amount of the tackifying resin, the hardness of the pressure-sensitive adhesive, and the like.

Depending on the types of the base material 1 and the pressure-sensitive adhesive layer 2, the surface 1a of the base material 1 on which the pressure-sensitive adhesive layer 2 is to be formed may be subjected to corona treatment, oxidation treatment, or the like, or to isocyanate or natural rubber. When an undercoat layer such as a rubber obtained by graft-polymerizing acrylic acid is formed, the adhesive strength between the base material 1 and the pressure-sensitive adhesive layer 2 can be improved.

[0018]

According to the above construction, the curing member is brought into close contact with the floor surface with the adhesive, thereby preventing infiltration of water into the floor surface, displacement and breakage of the curing member, and forming the curing member on the upper surface of the curing member. The unevenness prevents slippage on the curing member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to embodiments. It goes without saying that the present invention is not limited to these embodiments. Example 1 An uneven roll was pressed against one surface of a polyvinyl chloride film having a thickness of 105 µm to form unevenness. Then, on the other surface of the polyvinyl chloride film, 100 parts by weight of the grafted natural rubber, 35 parts by weight of a terpene-based tackifier, 1 part by weight of a thiuram-based vulcanization accelerator, 1 part by weight of a dimethylcarbamine-based vulcanization accelerator, A rubber-based pressure-sensitive adhesive comprising 2 parts by weight of zinc stearate and 3 parts by weight of a bisphenol-based antioxidant was applied, and dried at 140 ° C. for 3 minutes to obtain a cured member.

The center line average roughness Ra and the static friction coefficient (wet, dry) of the non-adhesive surface of the cured member and the adhesive force of the adhesive surface were measured by the following methods, and the results are as shown in Table 1. [Center Line Average Roughness] Using surfcom 554A (trade name, manufactured by Tokyo Seimitsu Co., Ltd.), measurement was performed at a measuring distance of 4 mm, a cut off of 0.8 mm, and a measuring speed of 0.3 m / min. [Static friction coefficient] A 1 kg load (the contact surface was made of chloroprene rubber) was placed on the non-adhesive surface of the curing member, and the load was pulled at a speed of 1 m / min, and the static friction resistance at this time was determined. [Adhesive strength] The adhesive surface of the curing member was S
Affixed to a US430BA stainless steel plate.
It was measured by a method of peeling 180 ° at a speed of 3 m / min.

[0021]

[Table 1]

The curing member is 150 mm long and 15 mm wide.
It was adjusted to 0 mm, and this was affixed to the surface of the Lauan plywood so that the width of the wrap was 20 mm. Next, water was sufficiently sprayed onto the surface of the floor material including the curing member with a dropper, and the mixture was left for 168 hours. Thereafter, when the curing member was peeled from the floor material and the surface of the floor material was observed, no water permeation was observed at all.

Comparative Example 1 A cured member was obtained in the same manner as in Example 1 except that no irregularities were formed on the surface of the polyvinyl chloride film.

Comparative Example 2 A cured member was obtained in the same manner as in Example 1 except that no pressure-sensitive adhesive layer was formed on the polyvinyl chloride film.

Example 2 A cured member was obtained in the same manner as in Example 1 except that the degree of formation of irregularities on the surface of the polyvinyl chloride film was increased.

Example 3 In Example 1, a polyvinyl chloride film was used as a polyethylene film, and a rubber-based adhesive was used as 100 parts by weight of 2-ethylhexyl acrylate-vinyl acetate copolymer, 20 parts by weight of xylene resin, phthalic acid A cured member was obtained in the same manner as above except that the acrylic pressure-sensitive adhesive was composed of 40 parts by weight of an ester plasticizer and 3 parts by weight of an isocyanate-based crosslinking agent.

Comparative Example 3 A cured member was obtained in the same manner as in Example 3 except that no irregularities were formed on the surface of the polyethylene film.

Example 4 A curing member was obtained in the same manner as in Example 3 except that the degree of formation of irregularities on the surface of the polyethylene film was increased.

For each of the cured members obtained in Examples 2 to 4 and Comparative Examples 1 to 3, the center line average roughness Ra and the static friction coefficient (wet, dr) of the non-adhesive surface were obtained.
y) and the adhesive strength of the adhesive surface were measured in the same manner as in Example 1, and the results shown in Table 1 were obtained. In addition, for each of the curing members, whether or not water had penetrated into the wrap portion when affixed to the floor material was examined in the same manner as in Example 1. As a result, a large amount of water had penetrated in Comparative Example 2. On the other hand, in Examples 2 to 4, it was recognized that water intrusion was significantly suppressed. In this test, in Comparative Example 2, instead of affixing the curing member to the floor material, it was fixed by temporarily fixing the adhesive member in four directions with an adhesive tape.

As apparent from Table 1 above, the cured member of the example in which the surface of the polyvinyl chloride film or the polyethylene film was formed with irregularities had more static friction on the surface than the comparative examples 1 and 3 in which the irregularities were not formed. The coefficient is large. In addition, in the curing member of the example in which the adhesive layer was formed, the infiltration of water into the wrap portion when applied to the flooring material was suppressed as compared with that of Comparative Example 2 in which the adhesive layer was not formed. ing.

[0031]

As described in detail above, the floor curing member of the present invention has the pressure-sensitive adhesive layer formed on one surface of the base material. Therefore, it is possible to prevent water from infiltrating into the floor surface, and to prevent displacement and breakage of the curing member. In addition, since the unevenness is formed on the upper surface of the curing member, the coefficient of static friction on the surface is large, so that slipping on the curing member is prevented. Therefore, the floor curing member of the present invention sufficiently prevents the floor from being stained, deformed, and discolored during construction of a house or the like, and also removes or shifts the blackened portion applied to the floor surface or the surface of the curing member. In addition, even when the curing member is wet with rain or the like, there is no danger of slipping and falling when walking on the curing member.
