Abstract

PURPOSE:To produce the subject chip which is not slippery and can substitute for wood chips. CONSTITUTION:100 pts.wt. polyethylene or polypropylene is mixed with at most 50 pts.wt. wood flour and at most 20 pts.wt. blowing agent or calcium carbonate in a specified mixing ratio, and the obtained mixture is optionally mixed with a biodegradability improver and a sterilizer to obtain the objective chips. Thus, industrial wastes (plastics) can be effectively used and the obtained chips are hygienic and economical because the biodegradability improver can degrade dung and urine of a race-course, and the sterilizer can kill bacteria and pathogenic bacteria carried by rainwater or the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a training course synthetic resin chip suitable for being installed and used in a training course for training a racehorse.

[0002]

2. Description of the Related Art Conventionally, in order to train a racehorse, chips are laid on a dirt course or a turf course by a predetermined thickness (for example, a length of 1500 m and a width of 10 m is 20 cm). Wood chips have been attracting attention as chips of this type, and it has been reported that the effect of training the legs of a racehorse becomes remarkable if the wood chips are used.

[0003]

However, in this case, the wooden chips may be decomposed or give off a bad odor due to the dung or urine of the racehorse, so that there is a disadvantage that enormous cost and equipment are required for the purification treatment. there were.

[0004] In recent years, on a global scale, nature conservation,
Environmental protection is being called for, and timber cutting tends to be suppressed and banned in response to this trend. As a result, it has become difficult to obtain timber, and the price of timber has been soaring that there has been a strong demand for an alternative to wood chips.

In view of the above circumstances, it is an object of the present invention to provide a synthetic resin chip for a training course that can be used instead of a wooden chip and that contributes to the effective use of industrial waste (plastic).

[0006]

That is, according to the present invention, 50 parts of wood powder is added to 100 parts of polyethylene or polypropylene.
It is composed by mixing at a compounding ratio of less than 1 part.

Further, the present invention is constituted by mixing a foaming agent in a mixing ratio of 20 parts or less to 100 parts of polyethylene or polypropylene.

Further, the present invention is constructed by mixing wood powder in a mixing ratio of 50 parts or less with 100 parts of polyethylene or polypropylene and mixing a foaming agent in a mixing ratio of 20 parts or less.

Further, according to the present invention, wood powder is mixed in a mixing ratio of 50 parts or less with 100 parts of polyethylene or polypropylene, and calcium carbonate is mixed in a mixing ratio of 50 parts or less, and further, if necessary. It is configured by mixing a biodegrading agent (for example, starch) and a bactericide.

Further, the present invention is constituted by mixing calcium carbonate in a mixing ratio of 50 parts or less to 100 parts of polyethylene or polypropylene and mixing a bactericide.

Here, the mixing ratio of the wood powder to polyethylene or polypropylene is limited to 50% or less. When the mixing ratio exceeds 50%, the synthetic resin chips for the training course become hard and the foot and waist of the racehorse are reduced. This is because it becomes unsuitable for training. Further, the blending ratio of the foaming agent to polyethylene or polypropylene is limited to 20% or less because if the blending ratio exceeds 20%, the training course synthetic resin chip loses its rigidity and the cushioning property becomes poor. .
Further, the mixing ratio of calcium carbonate to polyethylene or polypropylene is limited to 50% or less, because if the mixing ratio exceeds 50%, the synthetic resin chips for the training course become brittle (become shabby). This is to provide cushioning and weight.

[0012]

With the above-mentioned structure, the present invention works by mixing polyethylene or polypropylene with wood powder, a foaming agent, or calcium carbonate in a predetermined mixing ratio so as to be a material suitable for a training course of a racehorse. .

The biodegrading agent decomposes feces and urine of racehorses, and the bactericidal agent acts to kill bacteria and pathogens brought in through rainwater or the like.
