Abstract

PROBLEM TO BE SOLVED: To simplify the management of a riding ground by covering sand and a cushioning material constituted of paper, fibers, and chips with paraffin wax, a binder such as a terpene resin, and a surface active agent. SOLUTION: Paraffin wax, micro-wax, and vaseline are combinedly or singularly formed into an emulsion, and sand and a cushioning material are coated with the emulsion. Silica sand, mountain sand, sea sand, or their mixture is used for the sand. Paper, fibers, fabrics, wood, fibers of cork, tubes, or small pieces are used for the cushioning material. Anionic carboxylic acid salt or ester sulfate salt is formed into an emulsion for use as a surface active agent. The emulsion of a terpene resin is added as a tackifier to increase sticking to sand. The antifreezing performance, dustproof performance, and separation resistance performance are increased, and the solidification preventing performance, water-permeable performance, elastic performance, and coupling performance can be improved.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface layer material for outdoor sports facilities and baba facilities and the like. The present invention relates to a freeze-resisting property, a dust-proofing property and a separation-resistant property by emulsifying and coating the surface of sand with the special wax. The present invention relates to a buffer-permeable water-permeable pavement material which mixes with a cushion material to improve the solidification prevention performance, water permeability, elasticity and bonding performance of sand, thereby maintaining freshness as a pavement surface material.

[0002]

2. Description of the Related Art Conventionally, the surface material for a Baba facility often uses sea sand at a specific place as it is, and solidifies and solidifies during use.
Material separation is also intense, and it takes a great deal of labor and cost to maintain good horse riding conditions, such as daily harrowing and rehabilitation works every 1 to 3 years. did. Although various materials have been developed so far, it has been considered difficult to achieve the ideal baba. For example, according to many patents and utility models, sand is coated with synthetic resins, vegetable oils and mineral oils. However, all of these methods are complicated in use, making it difficult to ensure the safety of the operation, uneconomical, and far from feasible.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a buffer-permeable water-permeable pavement material which is simple to use, easy to work in, and economical.

[0004]

Means for Solving the Problems In general, the coating of synthetic resin on sand is performed by heating and melting a thermoplastic resin.
Alternatively, it is manufactured by heating sand to 200 ° C. or higher and fusing the synthetic resin, but there is a problem in work safety. For coatings of vegetable and mineral oils, for example,
Some have low flash points around ℃, and there is concern about flammability and adverse effects on the environment due to excess oil. Reactive synthetic resins are almost two-parts, are difficult to mix, and require a long time for curing. The present inventor has conducted extensive studies and found that paraffin wax, microwax, petrolatum polyethylene wax, petrolatum, etc. can be safely and easily coated on sand and cushioning materials by using a plurality or alone of a highly volatile emulsion. Was invented. For emulsions, anions, nonions, anions / nonions,
Any of cations can be used, but any of carboxylate, sulfate, sulfonate, and phosphate can be used since the anion is excellent in water resistance and weather resistance. In order to enhance the adhesion to sand, an emulsion of a terpene resin was added as a tackifier to give the adhesion. By adding paper, fiber, cloth, wood, cork, plastic, natural rubber, synthetic rubber, and other fibers, tubes, films, chips, and small pieces, dustproof performance, separation resistance performance, elastic performance, solidification prevention performance, and water permeability Performance,
The improvement of the freezing resistance performance and the coupling performance and the reduction of the maintenance cost have been achieved.

[0005] Paraffin wax, crystallin wax, petrolatum, petrolatum, and the like can be obtained from a high-boiling oil component in a refining process from petroleum crude oil through a sweating process and the like. Both are used for coating materials for food containers, cosmetics, etc., and are highly safe. Vaseline also has a positive effect on horse hoofs. Polyethylene wax of low molecular weight of polyethylene, Fischer-Tropsch wax derived from coal chemistry is also used in food packaging containers,
Used as an additive for the adhesive, it has been evaluated for good safety.

Surfactants include nonionic, anionic, nonionic / anionic, and cationic surfactants. Anionic surfactants are excellent in water resistance and weather resistance, and include carboxylate,
Emulsions were carried out using carboxylate salts, although sulfates, sulfonates and phosphates can be used.

As the tackifier, petroleum-based, rosin-based, and coumarone-based resins can be used. Among the terpene-based resins, there are colorless and odorless resins to which hydrogen can be added, which is excellent in weather resistance, water resistance, and safety. Therefore, the hydrogenated terpene resin was emulsified and added in an appropriate amount.

[0008] As the cushion material, for example, cylindrical polyfiber, hollow polyfiber, polyfilm,
By cutting the plastic to a diameter of 5 mm or less and a length of 1 mm to 5 cm, and mixing with the coating sand, the excess wax composition is absorbed into the pipe, and when a load is applied, the excess wax composition is discharged. It has the effect of replenishing the sand and does not retain the freshness and performance of the mixture in the long term.

[0009] 20 to 90 parts, preferably 40 to 70 parts, of sand which is silica sand, mountain sand, sea sand or a mixture thereof, 5 to 40 parts, preferably 8 to 30 parts of Vaseline emulsion, 0.1 to 5 parts of tackifier, preferably 0.5 to 3 parts, cushion material 10 mesh or less 0 to 50 parts, preferably 10 to 3
0 parts, 10-20 mesh 0-50 parts, preferably 5-3
0 parts was sufficiently mixed and stirred by a mixer, and the mixture was compacted in a cylindrical container having a wire mesh at the bottom to a thickness of 10 cm, and 10 l of water was discharged from the top at intervals of 2 days for 1 month. The mixture showed permeation of water, did not separate the materials, and was excellent in dustproofness. In addition, tightness is not recognized even in hardness, and it has moderate elasticity and can give tenderness to horse legs and hooves and human feet. No change was observed in 100 hours, 200 hours, and 300 hours (sunshine weather meter, equivalent to 2 years) even with ultraviolet irradiation by a weather tester, and good weather resistance was proved. For example, by paving the product of the present invention as a surface material for a track facility, it is possible to maintain a good track if harrowing is performed about once every two weeks and simple surface renovation is performed about once every 4 to 6 years. Can be done.

The product of the present invention is produced by appropriately mixing special wax, sand and cushioning material. The mixing ratio varies depending on the properties and shapes of sand and cushioning material used and the place of application. As shown in FIG.
