Description

  The present invention relates to a plate-shaped artificial soil floor, and more particularly to a method and apparatus for manufacturing a plate-shaped artificial soil floor that is thin and light, particularly suitable for growing plants on a rooftop.

Conventionally, artificial soil floors have been used in various places such as rooftop gardening measures such as rooftop gardening measures. As the raw material, fiber material is agglomerated in a plate shape, but wood chips that become natural planting substrates (artificial soil floors) by effectively using wastes such as thinned wood are attracting attention.
Wood chips are excellent in water retention (humidity retention) and have a phytoncide effect, and have the property of returning to nature while becoming nutrients of the soil after several years.
As a prior art of artificial soil floor made of wood chips, a super absorbent resin powder is added to the wood chips, and both materials are made into a desired shape with a sticky binder (binder) such as starch paste or agar. (For example, Patent Document 1 etc.).
The binder used for this is generally a urea-based adhesive or formalin-based adhesive used to bond wood-based materials. However, unlike the urea-based adhesive, it does not destroy the ecosystem, and the formalin-based adhesive It does not cause sick house syndrome.

However, adhesive adhesives such as starch paste and agar are temporarily good in adhesion to the wooden chip as the adherend, but they cannot dissolve to water and maintain a predetermined adhesive force. It is unsuitable for artificial soil floors that are closely related to the above, and there are fundamental problems that cracks occur before lawn and plants take root, or that the essential chip flows out and does not maintain a predetermined block form.
JP-A-8-266148

  The present invention has been made in view of the above-described conventional circumstances, and its intended treatment satisfies the functions as a natural planting substrate (artificial soil floor) in terms of water retention (moisturizing property), handleability, degree of rooting, and the like. An object of the present invention is to provide an artificial soil floor production method and production apparatus using wood chips as a raw material.

When the artificial soil floor using the wood chip generated from the waste such as the thinned wood is manufactured, the present inventors first improve the adhesive that binds the wood chip and does not cause harm to animals and plants. In particular, the use of adhesives that are harmless to plant growth.
There are urea adhesives, formalin adhesives, etc., as adhesives for adhering these woods, etc., but this time the wood chip adhesives are polyurethane resin adhesives, from polymethylene polyphenyl polyisocyanate It will be.
And this invention relates to the manufacturing method of the plate-shaped artificial soil floor using the polyurethane resin-type liquid adhesive which consists of polymethylene polyphenyl polyisocyanate as a wood chip binder, and its manufacturing apparatus.
The plate-like artificial soil floor of the present invention obtained by compressing and solidifying the wood chip achieves excellent shape retention, water retention (moisturization), good rooting, etc., and can be manufactured as an optimal natural planting substrate. became.

That is, the present invention is a manufacturing method,
Add a polyurethane resin-based liquid adhesive made of polymethylene polyphenyl polyisocyanate to a wooden chip, stir well, lay it on the mold to fill it up, and add the liquid adhesive in the mold to the wooden chip In a compressed state, spray the pressurized steam so that it spreads from above, and let the pressurized steam flow in a short time without stagnation in every corner to quickly cure and mold the polyurethane resin adhesive This is a method for producing a plate-like artificial soil floor (claim 1).

Then, the polyurethane resin-based liquid adhesive composed of polymethylene polyphenyl polyisocyanate is added at a weight ratio of 14 to 1 with respect to the wood chips, and stirred well so that it is evenly distributed. The wooden chip having a bulk of 9 cm was pressed with a pressing pressure of 0.6 t / cm ² and pressed to 5 cm by a stopper provided on the mold. Stop and spray 160-180 ° C. steam of 6-9 kg / cm ^{2 at} a spray pressure of 6-9 kg / cm ² from above onto the compressed plate-like wood chip for a short time, and quickly press the polyurethane resin adhesive with the pressurized steam. 2. The method for producing a plate-like artificial soil floor according to claim 1, wherein the artificial soil floor is hardened and molded (claim 2).

  According to the above production method, the polyurethane resin-based liquid adhesive composed of polymethylene polyphenyl polyisocyanate must be in an appropriate amount with respect to the wood chip, for example, a ratio of 50 g to 700 g of wood, that is, 14 to 1 Add by weight ratio. When the polyurethane resin-based liquid adhesive is added in excess of this ratio, the entire surface of the wood chip is coated and hardened with this adhesive to deteriorate the water retention, and the space in which the plants take root is reduced. Since the polyurethane resin liquid adhesive is expensive and expensive, it is disadvantageous because of its high cost. Further, the polyurethane resin-based liquid adhesive takes a long time if it is exposed to moisture even at room temperature. However, the polyurethane resin-based liquid adhesive is cured, so the polyurethane resin-based liquid adhesive is added to the wood chip, and the well-stirred moisture While it is hardened and is not difficult to handle, it is good to quickly lay it on the formwork and form the artificial soil floor at once.

The wooden chip, which is fully laid in the formwork, is pressed with a pre-pressure of 0.6 t / cm ² and is compressed to 5 cm in the formwork, and is stopped. The chip is not completely crushed, but at least water is retained between the wood chips, or a gap having a rooted space is formed.

Further, in order to cure the polyurethane resin liquid adhesive added to the wood chip, it is sufficient to inject steam of 160 to 180 ° C. having an injection pressure of 6 to 9 kg / cm ² for a short time. By spraying the heated steam, the steam spreads to every corner of the wooden chip in the mold, and at a temperature of 160 to 180 ° C., the polyurethane resin liquid adhesive is cured in a short time, and at the same time, the plant Conveniently, substances that are harmful to the growth of the plant are also released. In addition, if the wood chips are already hardened in a short time even if the pressurized heat steam is sprayed over a long period of time, the wood chips will retain a large amount of moisture, and the weight Since it becomes heavier and difficult to handle, it is better to have a short injection time.

Next, regarding the manufacturing apparatus of the present invention,
It is a manufacturing apparatus implemented to the manufacturing method of the plate-shaped artificial soil floor of Claim 1 or 2,
Polyurethane resin liquid adhesive made of polymethylene polyphenyl polyisocyanate is added to the wood chip, stirred well, and then laid on the mold so that it fills up immediately. The polyurethane resin liquid adhesive in the mold Pressurize the added wood chip and inject it into a compressed state so that the pressurized steam spreads from the top, and quickly flow the pressurized steam without stagnation in every corner to quickly cure the polyurethane resin adhesive. A method for producing a plate-like artificial soil floor according to claim 1 or 2, wherein the production method for producing a plate-like artificial soil floor is characterized by comprising:
A stirrer for stirring a wood chip and a polyurethane resin-based liquid adhesive composed of added polymethylene polyphenyl polyisocyanate, and a liquid bond that is disposed below the stirrer and is extruded from the discharge port of the stirrer Formwork placing area for placing the formwork on which the wood chip with additive added is placed, and continuously pressurizing steam from above while the wood chip in the formwork is compressed, secured in the area A slide having a molding area for forming a plate-shaped artificial soil floor by curing the liquid adhesive and a take-out area for taking out the molded plate-shaped artificial soil floor continuously secured in the area A press mechanism for compressing a wooden chip full of liquid adhesive added into the mold from the upper surface side into the mold, and stopping at the upper end of the mold; A plurality of nozzles are drilled in the pressing die of the press mechanism in order to bring the pressurized steam evenly into every corner of the wooden chip compressed in the frame, and the nozzle is injected from above into the wooden chip and into the molding area.

At the time of compression, the edge of the formwork serves as a stopper, and pressurization is stopped and the wood chip is not completely crushed. Then, a plurality of blocks are used to spray the pressurized steam onto the compressed wood chip so that the added polyurethane resin-based adhesive is cured to every corner in the mold in a short time. A plurality of nozzles (steam injection holes) arranged in a shape are formed in a pressing mold. On the other hand, a plurality of small drain holes are formed in the molding area directly facing the pressing die, and steam (moisture) penetrating therethrough is quickly drained, thereby avoiding the inconvenience of unnecessary contact of moisture with the wood chips.
