Abstract

(57) [Summary] [Purpose] A mesh sheet for slipping to prevent slippage of carpets, mats, or chair covers. [Structure] A silicone mesh sheet obtained by covering a mesh-like base cloth with a non-foamed silicone rubber. [Effect] By using a silicone rubber instead of a conventional foamed resin such as vinyl chloride, there is almost no change in physical properties over time, stable performance is exhibited even in high temperature and low temperature environments, and stains due to migration of plasticizer do not occur.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sliding mesh sheet for preventing displacement of chair covers, floor coverings, bed mats, and the like.

[0002]

[Prior art]

 When a carpet or mat is laid on the floor, there is a problem that the position shifts and people slip.Therefore, as a countermeasure for this, resin latex may be applied to the back surface of the carpet, adhesive tape may be used, or PVC may be used. The method of using a sliding sheet made of foamed resin as an underlay has been adopted. Since leather and leather-covered lace covers are also easily slipped off, thin sliding sheets are often used in the middle.

[0003]

[Problems to be solved by the device]

 The effect of resin latex lining as a slip on carpets and mats is not always sufficient. Fixing with adhesive tape will damage or stain the floor material when re-peeling. The sliding sheet made of foamed resin has a certain effect, but in the case of soft vinyl chloride, which is one of the many materials currently used, the plasticizer does not stain the flooring material or the elasticity caused by the loss of the plasticizer. Deterioration reduces the sliding effect. Even for natural leather and leather, the plasticizer of soft vinyl chloride causes a change in the gloss of the surface and impairs the appearance of furniture. In a situation where the temperature is high due to direct sunlight in summer, such as the inside of an automobile, such troubles occur more rapidly, and sometimes softening and deforming the resin. As described above, the conventional sliding sheet is liable to cause stains on flooring and furniture, and inevitably deteriorates performance over time. This is especially noticeable in environments exposed to high temperatures. An object of the present invention is to provide a sliding sheet which has almost no performance deterioration over time and is free from the risk of stains on an object.

[0004]

[Means for Solving the Problems]

 The present inventor, as a result of studies to solve the above-mentioned problems, found that a mesh sheet coated with silicone rubber has a sliding effect even on a floor with a paint finish that is slippery. Furthermore, silicone rubber shows high sliding performance without being foamed, hardly shows any change in performance over time, and since it does not use a plasticizer, there is no problem of its migration, and over a wider temperature range. It was confirmed that the physical properties are stable and that it is extremely suitable as an elastic body for slipping. The gist of the present invention is a silicone mesh sheet for sliding that is formed by covering a mesh-like base cloth with a non-foaming silicone rubber.

The mesh-like base fabric used in the present invention is made of a natural fiber, a chemical fiber, an inorganic fiber, or a mesh-like woven or knitted fabric made from a mixture of these, and has a thickness, a mesh The size of the eyes can be appropriately selected depending on the application. The silicone rubber used in the present invention is not particularly limited, but a Shore hardness of 20 to 40, more preferably 20 to 30, is suitable. In order to coat the above mesh-like base cloth by impregnation, coating, spraying, etc., a two-part crosslinkable liquid silicone rubber is suitable. A flame retardant, a colorant and the like can be added to the liquid silicone rubber as needed.

[0006] Next, the present invention will be described in detail with reference to examples. Using a polyester filament yarn of 75d, a 24-gauge Russell knitting machine produces a warp density of 19 / 25.4 mm and a weft density of 15 / 25.4 mm. Create a mesh base cloth. As the resin for coating the base cloth, an addition reaction cross-linking type two-part liquid silicone rubber of Bayer Synthetic Silicone Co., Ltd., a 1: 1 mixture of trade name Siloprene LSR50 40A and 5040B, and a viscosity of 6000 centipoise were used. Method was applied to both sides of the base fabric, and heat treatment was performed at 190 ° C. for 60 seconds. The amount of adhered resin was 85 g / m ² , the finished weight including the base fabric was 140 g / m ^{2, the} finished thickness was 0.48 mm, and the thickness of the coated rubber layer was about 0.17 mm. A 5 cm × 5 cm sheet of the obtained silicone mesh was placed on natural leather or a laser, a load of 1 kg was applied, and the mixture was left at 40 ° C. for 2 weeks and 4 weeks, and changes in the appearance of the surface of the natural leather and leather were observed. However, no abnormality was found. In addition, the silicone mesh itself was not deformed at all, and the sliding performance was not different from the initial stage.

[0007]

[Effect of device]

 According to the present invention, the non-foaming silicone rubber is used as the elastic body of the sliding mesh sheet instead of the conventional foaming resin such as PVC, and as a result, the sliding performance is not inferior to that of the conventional foamed resin product. Moreover, there is almost no change in physical properties over time, and the performance is stable even in high and low temperature environments. Flooring materials and household appliances will not be contaminated due to migration of plasticizer such as PVC resin.
