Abstract

More particularly, the present invention relates to a flocking mat, in which the root of the weeds growing in the vicinity of the road is kept alive, the flock is kept, the leaves and the stem are dried, and the fire is not caused by the geothermal heat or the cigarette butts being dropped This invention relates to a preventive mat.

Description

Anthracite mat {ANTI-WEED MAT}

The present invention relates to a flocking mat, more particularly, to prevent the acidification of the soil by preventing the roots of the weeds growing in the vicinity of the road, Butts and the like, so that the safety of the road side can be maintained.

Generally, a guide rail 10 is provided on the roadside inside the observer 20 as shown in the example of Fig. 1 in order to prevent a large traffic accident caused by the departure of the road on the road such as a highway or a national road, A traffic safety device 14 such as a reflection plate or a reflective sticker is attached to the support 12 of the guide rail so that the driver can recognize and operate the curve road at night.

However, since the weeds in the spring, summer, and fall are naturally generated around the guide rails and lose the usefulness of the traffic safety facilities such as the reflector, the driver may not recognize the curve road at night, There was also a problem of damaging the aesthetics of the road.

Due to these problems, the weed work has been periodically carried out by putting the weeds that are native to the guide rail around each road management subject. However, due to the strong self-sustenance of the weeds, It becomes impossible to grow.

The weeding work by the worker periodically carried out in this way is a great expense and also poses a risk of sickness and injury due to the mowing machine.

Thus, it is possible to effectively prevent the growth of weeds on the road side, thereby ensuring the identification of traffic safety facilities such as reflector and reflective stickers, eliminating the need to periodically remove worker weeds to remove weeds, The mats are installed to eliminate psychological discomfort.

However, conventionally, the fecalizing sheet is made of a simple vinyl material and made to be inexpensive, so that it is not permeable and permeable, so that air or water can not flow into the fecal material sheet, and grass roots such as weeds also die.

In other words, grass roots such as weeds flow on the roadside have a retaining force to keep the soil from falling down. When the roots are drowned, the problem is caused by the loss of soil due to the falling of the ground.

In order to improve this, a two-ply nonwoven fabric is laid and used. In this case, since it is a nonwoven fabric, even if it has breathability and permeability, permeability is poor due to two layers. .

In addition, if the cigarette butts dropped by the driver during operation are dropped on the mat, especially when the nonwoven fabric is dry under the dryer, such as during the summer season, the fire can easily occur.

Korean Patent Laid-Open No. 10-2006-0009667 (2006.02.01), "Method of applying fecal sheet" Korean Registered Patent No. 10-0763313 (September 27, 2007), "Structure of Pasture Sheet Using Velcro and Method of Construction thereof" Korean Patent Laid-Open No. 10-2014-0039968 (April 04, 2014), "roadside flap mat" Korean Registered Patent No. 10-1513261 (Apr. 13, 2015), "Artificial Matting Mat"

The present invention has been made in view of the above-described problems in the prior art, and has been made in order to solve the above problems. The present invention has been made to solve the above problems, and it is an object of the present invention to provide a soil- To prevent acidification of the road surface, and to prevent the fire from being generated by geothermal heat and cigarette butts, thereby maintaining the safety of the roadside.

As a means for achieving the above object, the present invention provides a flocking mat, wherein the flocking mat comprises a lattice-shaped grid and a two-ply structure having a structure of an integrated nonwoven fabric attached to an upper surface of the grid; The non-woven fabric is coated with a flame-retardant additive in addition to a green-based pigment. The flame-retardant additive is blended with 50 to 60 parts by weight of ethylene bis tetrabromophthalimide, 10 to 20 parts by weight of a polystyrene resin, 0.01 to 10 parts by weight, 20-30 parts by weight of a polyester low-melt fiber having a length of 0.02 mm, 30-40 parts by weight of polyvinyl acetate, 10-20 parts by weight of polydiazodiphenylamine, 50-60 parts by weight of expanded graphite, Silane 20-30 parts by weight, and aliphatic polyamine 10-20 parts by weight.

At this time, the grid is also characterized in that the polypropylene resin is injected into a double die and extruded to form a tubular body having a hollow inside.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a front view showing a state around a guide rail of a general road side. Fig.
2 is a view showing an example of a structure of a back mat according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIG. 2, the weed mat according to the present invention has a double-layered structure of the grid 100 and the nonwoven fabric 200.

At this time, the grid 100 is a lattice member, and is a means for ensuring ventilation, permeability, and permeability by separating the nonwoven fabric 200 from the ground at a certain height.

In particular, the grid 100 is formed so that a plurality of hollow tube-shaped unit pieces are bundled into a single bundle so as to be smoothly and positively installed when the grid 100 is installed on the ground to increase the deforming force according to the shape of the ground. , And it is preferable that these bundles are arranged in a lattice form.

To this end, the grid 100 may be formed into a tubular body having a hollow interior, that is, a tube, by extruding a polyester resin into a double die.

Therefore, when the grid 100 is placed on a grass such as a weed, the leaves of the grass pass through the grid-shaped space, so that the grid 100 is seated on the ground.

In addition, the nonwoven fabric 200 is a known nonwoven fabric 200, and is attached to the upper surface of the grid 100 to form an integral body.

Therefore, when the grid 100 is placed on the ground, the leaves of the grass are pressed by the nonwoven fabric 100, and since the grid 100 exists between the ground and the nonwoven fabric 200, the thickness of the grid 100 The nonwoven fabric 200 is spaced from the ground.

As a result, the nonwoven fabric 200 is made of a single layer, so that it has good air permeability, permeability, permeability, and does not adhere to the paper surface.

In other words, the present invention is a two-ply matting mat made of a grid-like grid 100 in contact with the ground and a nonwoven fabric 200 attached to the top of the grid 100, By securing all of the castles, grasses and stalks of grasses and grasses are dried and killed, and the roots can be saved and secured.

In addition, in the present invention, a green pigment is further added to the nonwoven fabric 200 to create a natural color. In particular, a flame-retardant additive is coated to prevent fire even if a cigarette butt is dropped by enhancing a flame-proofing function.

In this case, the flame-retardant additive is added to 100 parts by weight of the organic solvent, 50 to 60 parts by weight of ethylene bis tetrabromophthalimide, 10-20 parts by weight of polystyrene resin, 20 parts by weight of a polyester rosemating fiber 20 having a length of 0.01-0.02 mm 30 to 40 parts by weight of polyvinyl acetate, 10 to 20 parts by weight of polydiazodiphenylamine, 50 to 60 parts by weight of expanded graphite, 20 to 30 parts by weight of aminopropyltriethoxysilane, 10 to 20 parts by weight of aliphatic polyamine By weight.

Here, the organic solvent is preferably propylene acetate having low toxicity, and the flame retarding additive is made into a point liquid state.

The ethylene bistetrabromophthalimide is a chlorine-based flame retardant, which decomposes by heat to generate an incombustible gas to block off oxygen. If it exceeds 60 parts by weight, the viscosity increases and the coatability decreases. If it is added in an amount of less than 1 part by weight, the flame retardancy is deteriorated.

The polystyrene resin is excellent in heat resistance and impact resistance, and is added in the present invention in order to increase the compatibility with the flame resistant inorganic material while increasing the flame resistance. Therefore, it is not necessary to add an excessive amount, and 10-20 parts by weight is appropriate.

In addition, the polyester low-melt fiber should be pulverized to a length of 0.01-0.02 mm to improve durability and adhesion.

Particularly, the polyester low-melt fiber increases the durability by suppressing the generation of particles such as lint on the surface of the nonwoven fabric. When the amount is less than 20 parts by weight, durability and adhesion strength are not expected to increase. When the content is more than 30 parts by weight, It should be limited to the above range.

When the flame retardant additive is applied to the nonwoven fabric 200, the polyvinyl acetate is added to the nonwoven fabric 200 to minimize the possibility of separation at the interface. When the flame retardant additive is added at less than 30 parts by weight, If the amount is more than the weight part, the viscosity is increased to weaken the coating property, so that it should be limited to the above range.

In addition, the polydiazodiphenylamine is added to strongly adhere the polyvinyl acetate having adhesive properties to the surface of the nonwoven fabric 200 by using a photosensitive characteristic of being cured by a coupling reaction while being photolyzed when ultraviolet rays are encountered If it is added in an amount of less than 10 parts by weight, the strength of the coating is deteriorated. If the amount of the coating is more than 20 parts by weight, the curability is rapidly increased,

In addition, since the expanded graphite has a layered structure of graphite, when particles or small molecules are inserted between the layers and heat is applied, particles are expanded by several hundred times as they are separated like an accordion. It is a representative inorganic flame retardant used as a material, that is, an inorganic flame retardant.

If the amount of the expanded graphite exceeds 60 parts by weight, the curability and moldability are lowered. If the amount of the expanded graphite is less than 50 parts by weight, the flame retardancy and the fire resistance deteriorate.

In addition, the aminopropyltriethoxysilane is added for coupling of the resin added with the inorganic flame retardant and should be added in the range of 20-30 parts by weight in order to improve the bonding property, the adhesion property, and the surface strength.

And, the aliphatic polyamine is added in the range of 10-20 parts by weight to promote curing.

In addition, 30 to 40 parts by weight of sodium silicate was further added to 100 parts by weight of the flame retardant additive in order to induce gelation and to strengthen the surface fire resistance, Can be applied.

The flame-retarding additive according to the present invention thus formed is applied by immersing the grid-nonwoven fabric integral mat in the flame-retardant additive in an environment where the flame-retarding additive is maintained at 50-60 ° C.

In this case, the coating of the radiographic additives is firstly impregnated for 30 minutes, then dried for three to four hours at a shaded room temperature, then impregnated again for 30 minutes to form a second coating, then dried in a shade at room temperature for 5-6 hours, It is preferable to complete the coated surface having strong adhesion.

In order to confirm the flame retardancy of the flame retardant mat according to the present invention, flame retardant mat was prepared as a sample and compared with the conventional two-ply nonwoven fabric.

The flame retardant sample was prepared by mixing 50 parts by weight of ethylene bis tetrabromophthalimide, 15 parts by weight of a polystyrene resin, 20 parts by weight of a polyester low-melt fiber having a length of 0.01-0.02 mm, 40 parts by weight of vinyl acetate, 15 parts by weight of polydiazodiphenylamine, 60 parts by weight of expanded graphite, 20 parts by weight of aminopropyltriethoxysilane and 10 parts by weight of aliphatic polyamine.

The sample test was conducted by KS F2271, which is a flammability test method for building materials and structures.

As a result of the test, the sample according to the present invention was found to have grade 2 of flame retardant having semi-incombustibility, but the flame resistance could not be tested because the existing two-ply nonwoven fabric was burned.

Accordingly, it was confirmed that the flameproof mat according to the present invention has a certain flame retardancy.
