Description

  The present invention is used for road asphalt, concrete blocks (structures) such as curbs and median strips, houses, joints of parking lots or walkways, cement mortar, slate, brick or tile joints. And a suitable herbicidal treatment material.

  Conventionally, weeds with high reproductive potential grow over the road asphalt, concrete blocks (structures), surroundings of houses, joints of parking lots or walkways, cement mortar, slate, brick or tile joints. In many cases, weeding work is frequently performed because it not only deteriorates the landscape but also narrows the width of the road and deteriorates the visibility of the driver.

  Such weeding work is carried out by weeding or mowing by manual labor or the like, and spraying of a herbicide, but because of heavy labor and cost, various herbicidal structures or herbicidal treatment methods have been proposed. For example, as such, there is no need to fill up to an intermediate position in a groove that is recessed from the upper surface of the road pavement with a predetermined width and depth along the boundary between the road pavement and the boundary block. A grass barrier structure at a road boundary portion (utility model registration No. 3173280) provided with a shrinkable filler and a stretchable sealing material that closes the upper portion of the recessed groove so as to be stretchable has been proposed.

  Also, after filling the gap with a herbicide, the surface is filled with a filling material such as mortar, and an adhesive base coating such as a primer is applied to the top of the filling, and heating means such as a powerful gas burner is provided. It has been proposed to use it slowly and heat-stable to form a weedproof sheet (utility model registration No. 3114078).

  In addition, at the step joints between the road block and the pavement, a sloped cut is formed from the pavement surface toward the block, the pavement removal pieces removed by the sloped cut are removed, and a vertical cut is formed on the sloped surface by a cutter in the vertical direction. In addition, a guideway that opposes the optical and refracting properties is formed by the inclined surface and the vertical cut, and a herbicide material is attached to the guideway, and the repair material is filled in the removal traces of the grassproof material and the pavement removal piece. A method of forming a weedproof structure (Japanese Patent No. 5279945) has been proposed.

  However, the conventional herbicidal treatment material or the herbicidal treatment method requires a complicated herbicidal treatment and increases the cost accordingly.

  Accordingly, an object of the present invention is to provide a herbicidal treatment material that can suppress weed propagation in a boundary portion or the like by a low-cost and simple method and eliminate the need for weeding work.

  What solves the said subject is a weedproof processing material characterized by having a sheet material and the herbicidal treatment layer provided in the one surface side of this sheet material and containing the acrylic ester and the resin-type chip | tip. .

  The sheet material is preferably an inorganic sheet. The inorganic sheet is preferably a glass wool fabric. The resin chip is preferably a rubber chip or a urethane chip. The herbicidal treatment layer is preferably prepared by mixing 15 to 25% by weight of the acrylic ester aqueous solution and 75 to 85% by weight of the aggregate. The aqueous solution of the acrylate ester is preferably prepared by mixing 40 to 60% by weight of an acrylate ester and 60 to 40% by weight of water. The aggregate is preferably adjusted in particle size within a range of 0.3 to 1.5 mm.

  According to the invention described in claims 1 to 4, weed propagation at a boundary portion or the like can be suppressed by an inexpensive and simple method, and the weeding work can be made unnecessary.

It is a top view for demonstrating the other usage example of the herbicidal treatment material of this invention. FIG. 4 is a sectional view taken along line BB in FIG. 3. It is a top view of the other Example of the herbicidal treatment material of this invention. It is CC sectional view taken on the line of FIG. It is a top view for demonstrating the usage example of the weed prevention processing material shown in FIG.

  The present invention has a sheet material 10a and a herbicidal treatment layer 10b containing an acrylate ester and a resin chip provided on one surface side of the sheet material 10a. We realized a herbicidal treatment material that can suppress breeding and eliminate the need for weeding work by an inexpensive and simple method.

The herbicidal treatment material of the present invention will be described with reference to one embodiment shown in FIG. 1 or FIG.
The herbicidal treatment material 1 of this example is prepared by mixing an aqueous solution of an acrylate ester and an aggregate formed of a resin chip. Hereinafter, each configuration will be described in detail.

  When the herbicidal treatment material 1 is prepared by mixing an acrylic ester aqueous solution and an aggregate, the acrylic ester aqueous solution is in the range of 15 to 25% by weight, and the aggregate is in the range of 75 to 85% by weight. It is preferable to mix within. This is because if the aqueous solution of the acrylate ester is less than 15% by weight, the fluidity is insufficient and it becomes difficult to fill (apply) the boundary portion 2. If the aqueous solution of the acrylate ester exceeds 25% by weight, the solution is filled. This is because it will hinder the subsequent curing. More preferably, 20% by weight of an aqueous solution of an acrylate ester and 80% by weight of aggregate are mixed.

  It is preferable that the aqueous solution of acrylic ester is prepared by mixing within a range of 40 to 60% by weight of acrylic ester and 60 to 40% by weight of water. If acrylic acid ester and water are mixed within this range, it will maintain good fluidity during filling (coating) and harden well, and weeding work can be done in an inexpensive and simple manner by suppressing the growth of weeds. It is because it becomes the unnecessary herbicidal treatment material 1. More preferably, it is prepared by mixing the same amount of acrylic acid ester and water.

  The aggregate is compounded to firmly fix the herbicidal treatment material 1 to a required portion (boundary portion 2) and to increase the bulk of the herbicidal treatment material 1, and is composed of a rubber chip, a urethane chip or other resin system. It is formed with a chip. Thus, by using rubber chips, urethane chips or other resin-based chips as aggregates, the prepared herbicidal treatment materials have excellent weather resistance or long-term stability and are easy to manufacture. It becomes. Moreover, when the herbicidal treatment material is formed into a sheet shape as described later, the sheet can be easily cut. In this embodiment, the herbicidal treatment material 1 is composed only of resin-based chips. For example, any one of slag, natural stone, fired natural stone, ceramics, silica sand, or of these What mixed 2 or more types as an aggregate is also included under the category of this invention. In particular, slag is preferable because it easily impregnates an aqueous solution of an acrylate ester and is light and bulky and hardens in a short time to form a dense herbicidal treatment material layer.

  The aggregate is preferably adjusted in particle size within a range of 0.3 to 1.5 mm, and the aggregate is adjusted in particle size within this range, so that it is well mixed in an aqueous solution of an acrylate ester. The herbicidal treatment material 1 can be produced that retains moderate fluidity and hardens well, suppresses the growth of weeds, and eliminates the need for herbicidal work by an inexpensive and simple method.

Next, the herbicidal treatment material 10 shown in FIGS. 5 to 7 will be described.
The difference between the herbicidal treatment material 10 of this embodiment and the above-described herbicidal treatment material 1 is that the herbicidal treatment material 10 is not a liquid like the herbicidal treatment material 1 but is acrylic on one side of the sheet material 10a. A mixture (liquid) of an acid ester aqueous solution and an aggregate is adhered (applied) and cured to form 10b, which is formed into a sheet shape as a whole.

  Specifically, in the herbicidal treatment material 10 of this embodiment, an inorganic sheet (for example, a glass wool fabric) is used as the sheet material 10a, and an aqueous solution of an acrylate ester as shown in FIG. 10b is formed by applying and curing a mixture of the slab and aggregate with a thickness of about 3 mm. In use, as shown in FIG. 7, the herbicidal treatment material 10 is laid so that one end overlaps the upper surface of the boundary portion 2 or the like.

  Thus, the herbicidal treatment material of the present invention is not limited to a liquid material such as the herbicidal treatment material 1, and the herbicidal treatment material 10 is formed on the upper surface of the boundary portion 2 or the like by configuring it in a sheet shape. Weeding treatment can be easily performed only by laying. In addition, since the content of 10b is the same as that of the herbicidal treatment material 1, detailed description thereof is omitted. In addition, the present invention includes an adhesive layer on the lower surface of the sheet material 10a, and further having a release layer on the lower surface of the adhesive layer that is peeled off during use to expose the adhesive layer.

Further, a weedproofing method using the herbicidal treatment material 1 will be described with reference to one embodiment shown in FIG. 1 or FIG.
The herbicidal treatment method of this embodiment is a herbicidal treatment method for the boundary portion 2 between the bricks 5, and a step of preparing the herbicidal treatment material 1 by mixing an aqueous solution of an acrylate and an aggregate. The step of cleaning the boundary portion 2 and the application surface 3 around the boundary portion and then drying, the step of polishing the application surface 3 around the boundary portion, and the step of filling the boundary portion 2 with the herbicidal treatment material 1 The step of filling the boundary portion 2 with the herbicidal treatment material 1 includes the step of coating the coating surface 3 around the boundary portion with the masking tape 4, and the step of covering the boundary portion 2 and the boundary portion with the herbicidal treatment material 1. The coating surface 3 is coated with a thickness of 3 to 5 mm from the coating surface 3 and the masking tape 4 is peeled off. Hereinafter, each step will be described in detail.

  In the step of preparing the herbicidal treatment material 1 by mixing an aqueous solution of an acrylate ester and an aggregate, the aqueous solution of the acrylate ester and the aggregate are mixed and kneaded to prepare the herbicidal treatment material 1. It is preferable that the aqueous solution of the acrylate ester is mixed in the range of 15 to 25% by weight, and the aggregate is mixed in the range of 75 to 85% by weight. This is because if the aqueous solution of the acrylate ester is less than 15% by weight, the fluidity is insufficient and it becomes difficult to fill (apply) the boundary portion 2. If the aqueous solution of the acrylate ester exceeds 25% by weight, the solution is filled. This is because it will hinder the subsequent curing. More preferably, 20% by weight of an acrylic ester aqueous solution and 80% by weight of aggregate.

  The aqueous solution of the acrylate ester is preferably prepared by mixing within a range of 40 to 60% by weight of acrylate ester and 60 to 40% by weight of water. If acrylic acid ester and water are mixed within this range, it will maintain good fluidity during filling (coating) and harden well, and weeding work can be done in an inexpensive and simple manner by suppressing the growth of weeds. This is because an unnecessary herbicidal treatment material 1 is produced. More preferably, it is prepared by mixing the same amount of acrylic acid ester and water.

  The aggregate is blended to firmly fix the herbicidal treatment material 1 around the boundary portion 2 and the boundary portion, and to increase the bulk of the herbicidal treatment material 1, and is composed of a rubber chip, a urethane chip or other resin system. It is formed with a chip. Thus, by using rubber chips, urethane chips or other resin-based chips as aggregates, the prepared herbicidal treatment materials have excellent weather resistance or long-term stability and are easy to manufacture. It becomes. Moreover, when the herbicidal treatment material is formed into a sheet shape as described later, the sheet can be easily cut. In this embodiment, the herbicidal treatment material 1 is composed only of resin-based chips. For example, any one of slag, natural stone, fired natural stone, ceramics, silica sand, or of these What mixed 2 or more types as an aggregate is also included under the category of the present invention. In particular, slag is preferable because it easily impregnates an aqueous solution of an acrylate ester and is light and bulky and hardens in a short time to form a dense herbicidal treatment material layer.

  The aggregate is preferably adjusted in particle size within a range of 0.3 to 1.5 mm, and the aggregate is adjusted in particle size within this range, so that it is well mixed in an aqueous solution of an acrylate ester. The herbicidal treatment material 1 can be produced that retains moderate fluidity and hardens well, suppresses the growth of weeds, and eliminates the need for herbicidal work by an inexpensive and simple method.

  In the drying process after cleaning the boundary 2 and the application surface 3 around the boundary, the dust and dirt on the application surface 3 of the brick 5 are cleaned and removed. At the same time, if grass has already grown in the boundary portion 2, they are removed and then naturally dried.

  In the step of polishing the application surface 3 around the boundary portion, the application surface 3 of the brick 5 is polished by a polishing machine (for example, a sander), and the unevenness of the application surface 3 is ground to form the application surface 3 substantially flush. Thus, as shown in FIG. 1, the herbicidal treatment material 1 is attached to the coating surface 3 in a band shape so as to be surely fixed.

  In the step of coating the coating surface 3 around the boundary portion with the masking tape 4, as shown in FIG. 1, the width is about 50 to 100 mm in parallel along the extending direction of the boundary portion 2 and on both sides of the boundary portion 2. The masking tape 4 is temporarily bonded to both sides of the belt-shaped coating portion.

  In the step of applying the herbicidal treatment material 1 to the boundary part 2 and the application surface 3 around the boundary part, the application part 3 (eg, brush, roller, iron, etc.) is used to apply the boundary part 2 and the application surface 3 around the boundary part. The herbicidal treatment material 1 is applied to the part surrounded by the masking tape 4. This coating is preferably performed with a thickness of 3 to 5 mm from the coating surface 3, and thereby, a good herbicidal treatment material that can be fixed reliably without being easily peeled off in a short time (1 to 2 hours). A layer is formed. More preferably, the thickness is about 3 mm.

  In the step of peeling the masking tape 4, the masking tape 4 is peeled after the herbicidal treatment material 1 is cured. Through the above-described steps, the herbicidal treatment method at the boundary is completed. Thus, according to the herbicidal treatment method of the present invention, weeding work is achieved by suppressing the propagation of weeds at the boundary and the like by an inexpensive and simple method. Can be made unnecessary. Furthermore, the herbicidal treatment layer formed by the herbicidal treatment material 1 is excellent in light resistance, weather resistance, and durability, and can eliminate the need for herbicidal work over a long period of time.

Furthermore, the weed control method shown in FIG. 3 or 4 will be described.
The fundamental difference between the weedproofing method of this embodiment and the above-described weedproofing method is the difference in the required parts to be subjected to the weedproofing treatment, and the others are the same. The same components are denoted by the same reference numerals and description thereof is omitted.

  The target of herbicidal treatment of this herbicidal treatment method is a boundary portion 8 between the asphalt 6 and the curbstone 7. As described above, when there are steps on both sides of the boundary portion, the masking tape 4 is applied only to the upper surface of the lower asphalt 6, and the belt-like portion and the boundary portion 8 on the boundary portion 8 side of the portion where the masking tape 4 is applied. The herbicidal treatment material 1 is applied inside to carry out the herbicidal treatment.

Furthermore, the weed control method shown in FIG. 7 will be described.
The basic difference between the herbicidal treatment method of this example and the above-described herbicidal treatment method is that, in the process of preparing the herbicidal treatment material, a mixture of an aqueous solution of an acrylate ester and an aggregate is applied to the sheet material and It is the point which makes the herbicidal treatment material 10 harden | cure in a sheet form, and the point which stretches the sheet-like weedproof treatment material 10 in a required site | part (border part etc.) at the time of use.

  Specifically, in the production process of the herbicidal treatment material 10, as shown in FIG. 6, a mixture of an aqueous solution of an acrylate ester and an aggregate is applied to the upper surface of the sheet material 10a to a thickness of about 3 mm and cured 10b. Is formed, and the herbicidal treatment material 10 is produced. In addition, as the sheet material 10a, an inorganic sheet (for example, a glass wool fabric) can be preferably used. The content of 10b is the same as that of the herbicidal treatment material 1, and detailed description thereof is omitted. Furthermore, an adhesive layer may be provided on the lower surface of the sheet material 10a, and further, a release layer may be provided on the lower surface of the adhesive layer so that the adhesive layer is exposed during use.

  And, in use, as shown in FIG. 7, the sheet-shaped herbicidal treatment material 10 is attached to the upper surface of a required portion (boundary portion 2 or the like) with an adhesive agent so that one end is overlapped with each other. It is used by covering the required part by laying.

  Thus, the weedproofing material of the present invention is configured in a sheet shape, so that it is possible to easily perform the weeding treatment only by laying the weedproofing material 10 on the upper surface of the boundary portion 2 or the like.
