Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a turf body that is easy to manufacture and in which seeds do not move after being erected.

(Prior Art and its Problems) There are various kinds of conventional turf materials, but most of them are made by adhering or polymerizing seeds, fertilizers, etc. to paper, net, straw, nonwoven fabric, etc. with an adhesive.

On the other hand, the following effects are expected from the Zhangshiba body.

In other words, when the turf material is stretched on the soil surface, seeds,
Immediate contact with the soil surface is an essential requirement for early seed germination, and it is also important to ensure that the seeds and fertilizer do not fall off and move while transporting the turf to the construction site or during construction. It is a requirement.

Therefore, the applicant used a water-soluble glue to attach thin cotton to a net or a net having a storage part that could accommodate fertilizer bags, and then attached seeds, fertilizers, etc. to the thin cotton using a water-soluble glue. We have proposed a stretched turf body and have actually commercialized it and put it into use.

However, these products also had the following problems.

Water-soluble glues do not dry quickly, so special large-scale drying equipment is required for short-term production.
The drawback was that the product was expensive.

Furthermore, since it is necessary to apply high temperatures during drying,
The drawback was that the germination rate of seeds was reduced.

In addition, turf materials with seeds and fertilizers attached using a water-soluble adhesive are suitable for early contact with the ground surface, but seeds and fertilizers may fall off and move during transportation of the turf material to the construction site or during construction. In addition, it has been pointed out that the seeds come into contact with the ground too quickly, causing them to move and causing uneven germination and growth.

Therefore, the inventors of the present invention began research on a new turf material that can solve these problems.The net and pine are glued together using a water-soluble glue, and the adhesive is strong enough to attach seeds and fertilizer to the pine. The present invention was developed based on the belief that the above-mentioned problems could be solved at once by using a fast-drying adhesive.

(Means for Solving the Problems) That is, the present invention involves gluing pine trees on which seeds can germinate and grow using a water-soluble glue, and attaching the seeds and fertilizer to the pine tree using a fast-drying, water-insoluble glue. It is a turf body that is pasted with an adhesive.

The configuration of the present invention will be explained in detail below.

First of all, among the materials constituting the stretched turf body of the present invention, the net can be any vegetable, chemical, or metallic material as long as it is strong enough to adapt to the undulations of the slope and have the ability to block soil. However, chemical nets such as polyethylene or nylon are generally used. There is another type of net that has a storage section that can accommodate fertilizer bags.The manufacturing method for this net is to stack two sheets of chemical net to hold 20 to 60 bags of fertilizer.
In this method, a non-woven part of about 5 cm is created at every centimeter interval, and this non-woven part is used as a storage part for the fertilizer bag, and in this way, a net having a storage part is completed.

First, a mat capable of germinating and growing seeds, such as thin cotton mat, nonwoven fabric, or water-soluble paper, is adhered to the above-mentioned general net or a net having a storage section using a water-soluble glue such as polyvinyl alcohol.

Next, a certain amount of seeds, fertilizer, and sometimes a water-retaining material are spread on the pine, and then glued with a quick-drying, water-insoluble glue.

Quick-drying water-insoluble glues include urethane resins, urea resins, polyols, polyisocyanates, etc. These are used as a protein-based aqueous solution or mixed with water, and when they are used, they harden and foam. It acts as a glue.

When the above-mentioned operations are completed, in the case of a net having a storage section that is to be used as a turf body, a bag filled with fertilizer, water retaining material, etc. is stored in the accommodating section to complete the turf body.

(Effects of the Invention) As described above, the present invention involves gluing pine trees on which seeds can germinate and grow to a net with a water-soluble glue, and attaching the seeds and fertilizer to the pine in a fast-drying, water-insoluble glue. Since the turf is made of turf that is glued to the ground, when it rains, the nets and pine will immediately separate and the pine will come into contact with the ground surface.

When the pine tree comes into contact with the ground, the seeds are affixed with a glue that is insoluble in water, so they do not move and begin to germinate immediately.

The present invention is characterized in that, as described above, the net and pine are glued together using a water-soluble glue, and the pine, seeds, and fertilizer are attached using a quick-drying, water-insoluble glue. Even though the seeds and fertilizer come into contact with the ground immediately after rainfall, it has the effect of preventing the seeds and fertilizer from moving or separating during transportation or construction.

Furthermore, attaching seeds and fertilizers to pine trees uses a fast-drying, water-insoluble glue, so large-scale drying equipment is not required, making it economical.
Since there is no need to apply high temperatures during drying, there is also the effect that the germination rate of seeds does not decrease.

Therefore, an ideal material for the turf material was created.
