This invention relates to sliding beads made of synthetic resin. ``Advanced technology'' Previously, a method was proposed to create an artificial ski slope by laying synthetic resin sheets with a special surface structure on sloping ground.
For example, Japanese Patent Publication No. 45-3506, Japanese Patent Publication No. 45-3
2190, Japanese Patent Publication No. 47-38103, Japanese Patent Publication No. 48-39061), and some of them have been put into practical use.

滑走路面が提案されている。However, these conventional runway surfaces have the disadvantage that they are hard and prone to scratches and, in some cases, to injuries when a skier falls. To eliminate the above drawbacks, a runway surface described in Tokubatsu No. 71135/1984 has been proposed.

散布装置が必要である。The runway surface proposed here covers the surface of a synthetic resin artificial grass-like molded sheet with spherical synthetic resin pellets, and then water or silicone oil is applied as a lubricant to the sheet surface and pellets. Spreading it improves the sliding properties of the sheet surface. However, this runway surface still has the following drawbacks. ■ A lubricant or water distribution device is required.

■ 液体潤滑剤はＬ散布の際、ミストが大気中に飛散し

環境汚染の恐れがある。■ When liquid lubricant is sprayed with L, mist is scattered into the atmosphere, and excess liquid lubricant becomes waste liquid and flows out.
There is a risk of environmental pollution.

提供することにある。"Problems that the invention seeks to solve" The present inventor has arrived at the present invention as a result of various studies to solve these inconveniences. To provide sliding beads made of synthetic resin that can be scattered on the runway surface of an artificial ski resort, improve the sliding performance of the sheet surface, and maintain excellent sliding performance.

布する滑走用ビーズに存する。"Means for Solving the Problems" The gist of the present invention is that the surface of synthetic resin beads with a diameter of 2 to 5 ribs is coated with a low melting point lubricant having a melting point of about 40 to 10,000. Viscosity at room temperature is 300 ratios
(Centistokes) This consists of beads for sliding on the runway surface of an air ski resort, which are coated with the following low viscosity lubricant.

肋の粒径が適当である。Synthetic resin beads should have a rounded shape and moderate hardness so as not to damage the ski sole.
Particularly suitable are those foamed or impregnated with a suitable surfactant. If the bead size is too small, it will impede gliding properties, and if it is applied to an artificial ski resort where the runway surface is made of a synthetic resin artificial lawn-like molded sheet, it will not fit tightly into the gaps between the leaves. Depending on the shape of the leaf and the degree of shield density,
It is best to select the size appropriately, usually 2 to 5
The grain size of the ribs is appropriate.

２種以上のものを混合して用いてもよい。It is also possible to mix and use beads of various particle sizes.
Depending on the selection, the way the gaps between the leaves are filled and the mobility of the beads when applying an edge will vary. For example, if the particle size is small, it will feel like "powder snow," and if it is large, it will feel like "W-rough snow." You can get each feeling, and you can freely change the feeling of gliding. The low-viscosity lubricant used in the present invention is preferably a liquid such as silicone or ethylene glycol, which is non-toxic in terms of health and safety and has a viscosity of up to 300 s at room temperature. It is unsuitable because it easily runs off, and on the other hand, a lubricant with a viscosity greater than 300 ratio S is undesirable because it becomes sticky and has a negative effect on sliding properties.The low melting point lubricant used in the present invention is , if the ski speed increases,
Something that melts due to frictional heat and can maintain the interface between the ski sole and beads in a state of fluid lubrication, such as stearic acid,
It is preferable to use a material that has a surface affinity with synthetic resin beads, such as paraffin, and has a melting point of about 40 to 100°C. When synthetic resin beads are coated with a low-viscosity lubricant containing a low-melting-point lubricant, the lubricant can be prevented from flowing away and the gliding properties can be sustained, compared to beads coated with only a low-viscosity lubricant. There is. The low viscosity lubricant and low melting point lubricant used in the present invention may be used alone or in combination of two or more.

対し、低粘度潤滑剤と低融点滑剤との重量総和が０．０
５〜１の重量部の範囲が適当である。The degree to which the surface of the synthetic resin beads is coated with the low viscosity lubricant and low melting point lubricant depends on the specific surface area of the beads, the surface condition, and the ease with which the low viscosity lubricant and low melting point lubricant wet the bead material, etc. Selection is made as appropriate, but considering economic efficiency and appearance, the total weight of the low viscosity lubricant and low melting point lubricant is 0.0 per 100 parts by weight of synthetic resin beads.
A range of 5 to 1 part by weight is suitable.

After that, it may be cooled, or the low viscosity lubricant and the low melting point lubricant may be flooded to the above temperature in advance to form a liquid mixture, and this may be mixed with the beads.
