DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunctional non-slip base sheet, which is lightweight, flexible, elastic, waterproof, water-absorbing, wet-heat-alkali resistant, washing-resistant and antibacterial. It has a combined function to prevent the falling of the placed article, which can control the degree of anti-slip on the front and back surfaces in addition to the anti-slipping property and flame resistance.
And a multifunctional non-slip substrate sheet.

[0002]

Conventionally, when the rug mats room, as placed in corridors and stairs, mats or the like and its own weight, shea coated with a resin latex - bets materials used, whereby sheet - DOO shape Processing for increasing the frictional resistance of the back surface of the material is performed. For example, in Japanese Patent Publication No. 55-12251,
Underlay net for preventing slippage of material, Tokiko 3-29301
In the publication, layers of rubber or so-called soft type resin having a high degree of adhesion such as vinyl chloride resin or acrylic resin, polyurethane resin, etc. are used for fabrics, knits, paper, etc. Coated or layered on the back surface of the sheet, or coated on the back surface of the sheet material with a slip-resistant material with a highly adhesive material, a rubber-like soft material having a large friction coefficient, or a foam sheet or resin latex. There has been proposed a process using a sheet material or the like to increase the frictional resistance of the sheet material.

[0003]

However, those having the above-described back surface processing have many disadvantages such as lack of flexibility, poor texture and feel, inability to wash easily, and poor water absorption. . In particular, door mats, bath mats, and the like, even for general household use, require a soft feel because they are stepped on with bare feet, require frequent washing, and are required to have water absorption. Further, indoor equipment such as a vase is often placed on a rug or the like, also serving as an indoor aesthetic. In addition, in the current mica era and the spread of vending machines for beverages and the like, beverage cans placed in front of the driver's seat and the like often fall. Furthermore, in a substrate having a conventional foam layer, the foam is easily deformed or broken by external pressure or friction, and since the foam layer is thin and a thermoplastic resin is used, the heat resistance is poor, and the soundproofing material and It could not be used as heat insulator. further,
In While cleat is significantly improved in recent years, returned slip degree sliding is hampered because the work excess, composite, including the up fall prevention figurine product placement with excess slip degree
There is a need for an improved multifunctional anti-slip substrate sheet with functions .

The above-mentioned elastic foam-containing sheet has low strength and is bulky, so that its use and dimensions are limited, the degree of freedom against deformation is relatively low, and the slip-preventing effect is obtained. Has the disadvantage that it is not enough. For this reason, these foam sheets and the like have the drawbacks that they are easily broken by external pressure and collapsed, and the slipping and fastening effects are significantly reduced. As described above, in particular, the foam sheet has a high degree of freedom for deformation and has a complicated surface on which the unevenness is easily formed, so that the friction resistance is high, but the robustness of the coating layer itself is low. Inferiority, furthermore, poor texture washability and inferior change with time.
And, as a non-slip sheet material, in addition to the anti-slip effect, in addition to waterproofness, wet heat alkalinity, washing resistance, or water absorption, in addition to the feeling of texture in use,
In view of recent social circumstances, a multifunctional anti-slip base sheet having antibacterial properties and flameproofing properties has been desired.

[0005] The present invention is lightweight, flexible and resilient,
It has multi-functions such as waterproof, moist heat alkalinity, washing resistance, water absorption, antibacterial property, flameproofing, etc., vehicle interior material, interior material, clothing, packaging material, electric material, sporting goods material, It is an object of the present invention to provide a multifunctional anti-slip base sheet which can be suitably used in a wide range of fields such as medical materials, marine materials, aviation, and other industrial materials.

According to the present invention, a thermosetting binder-resin layer containing heat-expandable microcapsule particles is provided on at least one surface of a substrate made of woven fabric, knitted fabric or nonwoven fabric, felt, paper or the like. It is an object of the present invention to provide a multifunctional anti-slip substrate sheet characterized by the above. Further, the second object of the present invention is to improve the anti-slip effect and to combine various functions such as waterproofness, resistance to moist heat and alkali, and water absorption, and to freely control the sliding start angle by surface friction as required.

[0007]

In order to achieve the above object,
In the present invention, (1) a flexible sheet-like substrate such as a cloth is adopted as the substrate sheet. As a result, the back surface is subjected to a non-slip treatment, which leads to improvement of disadvantages such as lack of flexibility, poor feel, inability to wash easily, and inability to use both sides. (2) As the thermosetting resin composition, a thermosetting resin composition mainly containing a diene-based liquid polymer having a reactive functional group such as reactive active hydrogen is adopted.
The coating is excellent in heat resistance and alkali resistance, and has a polar group, so that it has excellent adhesion to a substrate sheet such as a cloth, so that it has a durable waterproof function. it can. (3) Thermal expansion microcapsules are usually 20
An average particle size of 20 to 40 μ in a region slightly lower than ８０80 μ is adopted, and the expansion start temperature is also the ordinary heat treatment temperature of 130 to 15 μm.
Heat treatment is performed in a slightly lower range of 110 ° C. to 130 ° C. than 0 ° C. Thereby, in the foaming of the thermally expandable microcapsule particles in the thermosetting resin composition, it is possible to improve the frictional resistance by increasing or equalizing the surface area as much as possible, and to combine durability and adhesion, It acts on the strength, expansion ratio and coating of the foam to increase the strength of the foam. In addition, since a thermosetting resin having a polar group is adopted, the affinity with the thermosetting resin binder layer and the adhesive strength are improved. (4) In applications where multiple functions such as water absorption, antibacterial properties, and flameproofing are desired in addition to waterproofness, a water-absorbing agent, an antibacterial agent, a flameproofing agent, and the like capable of imparting such functions are appropriately added. Can be achieved by: However, for example, when a filler is blended, foaming may occur in the product due to the influence of absorbed water and the like.To prevent such a foaming phenomenon, a water-absorbing filler rich in water spray is used alone. Alternatively, a combination and a combination for imparting desired various functions, such as using two or more kinds in combination, can be adopted.

[0008] In the thermosetting binder-resin layer having the above constitution, in the sliding test for surface friction, the sliding start angle is about 25 to 30 degrees without the non-slip processing, and about 40 to 45 degrees for the commercially available non-slip. In contrast, the preferred process combination in the present invention can achieve an average sliding onset angle of at least about 50 degrees or more, preferably about 60 degrees or more.

Further, in the present invention, selection of a flexible base sheet, and specification of factors such as blending of a thermosetting resin composition, selection of heat-expandable microcapsules, and setting of particle diameter and expansion start temperature, etc. , And the combination of these processes, for example, starting the average sliding on the back side to prevent the table from falling due to excessive degree of non-slip surface, which is a problem when moving tableware, cups and the like on a tray. The angle is at least about 50 degrees or more, preferably about 60 degrees or more, while the sliding start angle in the thermosetting binder-resin layer on the surface side is set slightly lower at about 40 degrees and the surface friction is slightly controlled. Multi-functionality with combined functions that utilize the degree of freedom possible and prevent the articles placed on the surface of a synthetic resin molded product such as a tray from overturning due to an excessive degree of surface non-slip. Ri stopper substrate sheet - may be bets configuration.

[0010] Thus, in the present invention, if necessary, improvement is desired as an additional disadvantage of the non-slip material, and in practice, the degree of non-slip of tableware and the like can be appropriately or optimally controlled and set, that is, the degree of surface non-slip In order to prevent the slipping over phenomenon such as the overturning of the placed article due to the excess, the structure of the non-slip base sheet which can exhibit the composite function as described above can be obtained.

That is, as a synthetic resin molded article, a non-slip synthetic resin molded article such as a thermoplastic polyurethane elastomer layer or the like, and a sliding start angle of about 40 degrees for tableware and trays which are considered to be ideally controlled in practical use. Although it is controlled in the vicinity of the degree, in the present invention as well, since it is possible to slightly control the sliding start angle to about 40 degrees in the vicinity as required, it is possible to form a multifunctional member such as preventing excessive slipping. . As described above, the present invention has excellent anti-slip effect, light weight, flexibility, elasticity, waterproofness, moist heat alkali resistance, washing resistance, antibacterial properties, flame resistance, etc. It is possible to obtain a non-slip base sheet having a configuration capable of exhibiting a composite function in which the degree of surface non-slip is controlled in addition to multiple functions.
