Description

Loess guard for tree protection and construction method using the same}

This relates to red clay guards and construction methods using them.

The growth of trees is greatly affected by external environmental changes, stress, etc., and the defect rate of trees is increasing due to recent climate change. Accordingly, various methods are being used to protect trees, one of which is applying red clay to trees. Applying red clay to trees has a variety of effects, including protecting the trees from wounds, preventing pests, preventing moisture evaporation, maintaining temperature and humidity, and preventing bacterial infiltration. It is also effective in landscaping due to the color of red clay similar to that of trees.

However, the existing tree protection and management products have not been verified for their function, such as greening hemp using jute, a plant fiber, and red clay hemp from China, and imported tree protection materials are prone to rot, lack of pest control, sprouting, and solidification after initial planting. There is a problem in that things like this occur.

Therefore, in order to solve the above problems, it is necessary to develop a red clay guard to respond to climate change and to promote tree growth by applying it to the tree trunk.

One aspect is to provide a red clay guard to protect trees.

Another aspect is to provide a method of constructing the red clay guard on a tree.

One aspect provides a red clay guard to protect trees.

The red clay guard is a red clay guard containing a mesh structure, and may be formed by using polyester as a warp yarn and cotton as a weft yarn, and crossing the warp yarn and the weft yarn. In addition, the red clay guard may be a red clay composition containing 10 to 60% by weight of red clay and 3 to 6% by weight of resin based on the total weight of the composition applied on an absorbent cloth.

In one embodiment, the red clay guard may include a square mesh structure. The mesh structure may have individual pores of 2.0 mm ² or less. For example, the hole may be 2.0 mm ² or less, 1.8 mm ² or less, 1.6 mm ^{2 or} less, 1.4 mm ² or less, or 1.0 mm ^{2 or} less. Additionally, the mesh structure may include holes whose dimensions (width x height) of each hole are 1.2x1.2 mm or less. The dimensions of the individual holes of the mesh structure in terms of width, width and height are, for example, 1.2x1.2 mm or less, 1.0x1.0 mm or less, 0.8x0.8 mm or less, 0.6x.0.6 mm or less, or 0.2x0. It may be 2 mm or less. At this time, if the individual size (area of pores) of the mesh structure is less than the above range, the red clay composition cannot pass through the adsorbent cloth and thus cannot be applied to the trees. Therefore, tree protection, external wound treatment, and boring pests are prevented by the red clay composition. There is a problem in that it does not sufficiently exert the effects of pest control, prevention of bacterial infiltration, prevention of moisture evaporation, buffering/warmth effect, extermination of wintering insects, or improvement of tree vitality. In addition, when the individual size (area of pores) of the mesh structure exceeds the above range, there is a problem in that the red clay composition is not sufficiently adsorbed on the absorbent cloth because the amount of the red clay composition passing through the absorbent cloth is excessive.

In another embodiment, the red clay composition may include 10 to 60% by weight of red clay and 3 to 6% by weight of resin based on the total weight of the composition. Specifically, the red clay is, for example, 10 to 60% by weight, 10 to 55% by weight, 10 to 50% by weight, 10 to 35% by weight, 10 to 30% by weight, 15 to 60% by weight, based on the total weight of the composition. , may be included in 15 to 55% by weight or 15 to 25% by weight. At this time, if the content of the red clay is less than the above range, there is a problem in that the purification, sterilization or protective effect, which is the inherent function of the red clay, cannot be sufficiently exerted. If it exceeds the above range, the adhesiveness of the red clay guard decreases and the adhesiveness of the damaged area decreases. There is a problem.

In addition, the resin serves as a binder that allows the red clay composition to bind to the absorbent cloth. The resin may be an eco-friendly resin or a synthetic resin. Eco-friendly resins include, for example, rosin, cellulose, petroleum resin, fatty acid, tarp, rosin, cowpearl, amber, elimi, kauri, manila, and frankincense. It may be resin, shellac, casein, etc., and the synthetic resin may be, for example, epoxy resin, phenolic resin, urea resin, melamine resin, fluorine resin, alkyd resin, acrylic resin, ethylene vinyl acetate, etc. The resin is, for example, 3 to 6% by weight, 3 to 5.5% by weight, 3 to 5% by weight, 3 to 4.5% by weight, 3.5 to 6% by weight, 3.5 to 5% by weight, or 3 to 3% by weight, based on the total weight of the composition. It may be included at 4% by weight. At this time, if the content of the resin is less than or exceeds the above range, the red clay composition does not completely bind to the adsorbent fabric, so when the red clay guard is applied to the trees, the purpose of constructing the red clay may not be sufficiently achieved. In addition, the flexibility of the red clay guard is low, so there is a problem that the red clay guard does not deform according to the shape of the tree when installed on a tree.

In addition, the red clay composition includes 0.1 to 1% by weight of wood vinegar, 0.1 to 2% by weight of electrodepositor, 1 to 3% by weight of pulp, 0.1 to 0.5% by weight of thickener, 2 to 4% by weight of moisturizer and/or 0.1 to 0.1 to 3% by weight. It may additionally contain 0.8% by weight of preservative.

In another embodiment, the red clay guard includes the steps of using polyester as a warp yarn and using cotton as a weft yarn to produce a red clay adsorbent fabric in which a mesh structure is formed by intersecting the warp yarn and the weft yarn; And it may be prepared by heat-compressing and adsorbing a red clay composition containing 10 to 60% by weight of red clay and 3 to 6% by weight of resin based on the total weight of the composition to the red clay adsorbent cloth.

In the step of manufacturing the red clay absorption cloth, weaving and weaving processes may be performed. During the weaving process, in the warping step, a predetermined number of warp threads according to the length of the fabric to be manufactured are prepared by arranging the length and tension to have a uniform width and winding them on a drum or beam. It can be included. Additionally, the weaving step may include the process of opening the warp yarns wound in the warping step vertically and alternatingly using healds, and then inserting the weft thread between them. At this time, the process of pushing the inserted weft between the warps and opening it in the opposite direction to insert the weft can be repeated.

In the step of adsorbing the red clay composition to the absorption cloth, the heat compression may be performed at a temperature of 40 to 100 ° C. Additionally, the adsorption may be performed for 10 to 60 seconds. The thermal compression may be performed, for example, at 40 to 100°C, 40 to 90°C, 40 to 80°C, 40 to 70°C, 50 to 90°C, 60 to 80°C, or 70 to 90°C. Additionally, the adsorption may be performed for 10 to 60 seconds, 10 to 50 seconds, 10 to 40 seconds, 20 to 55 seconds, 20 to 45 seconds, or 25 to 35 seconds. At this time, if the heat compression temperature and adsorption time are less than the above range, the red clay composition is not sufficiently dried and the red clay composition is not adsorbed on the absorbent cloth, so there is a problem that the holding power is reduced after construction on trees. If it exceeds the above range In this case, there is a problem that soot is generated on the red clay guard.

Another aspect provides a method of constructing a red clay guard according to one aspect to a tree. The specific details of the red clay guard are as described above.

In one embodiment, the method includes applying the red clay guard to a tree; It may include the step of hardening the red clay guard on the tree by spraying water on the red clay guard.

In another embodiment, the method includes softening the red clay guard by immersing it in water for 10 to 40 minutes; And it may include the step of applying the red clay guard to the trees.

In the step of wrapping the red clay guard around a tree, the red clay guard is rolled up to the uppermost part where it is to be constructed, and at this time, the red clay guard may be wound so that it overlaps by about 10 to 50%. After wrapping the red clay guard to the desired height for construction, the red clay guard can be fixed using a tacker.

As described above, the red clay guard according to one aspect has the advantage of shortening the construction step by heat-compressing and adsorbing the red clay composition on the absorbent cloth, unlike the method of wrapping the absorbent cloth around the tree and then additionally applying the red clay composition. there is. In addition, since the red clay composition is adsorbed on the adsorbent cloth, adhesion and durability have increased, so after constructing the red clay guard on trees, problems such as the occurrence of defects due to weather such as high temperature and rainfall and the resulting re-construction can be solved. .

The red clay guard according to one aspect uses eco-friendly materials and domestic red clay, and can not only promote the growth of trees but also improve the design of landscaping space.

[Experimental example]

Check bonding strength according to absorbent fabric

The binding force of the red clay composition according to the absorbent fabric of the red clay guard according to one embodiment was confirmed. Specifically, the red clay composition of Example 1 was thinly applied to the red clay adsorption cloth of Preparation Examples 1 to 3, and then heat-compressed for 30 seconds at a temperature of 40 to 100 ° C to prepare a red clay guard. Afterwards, the red clay guard was soaked in water at room temperature for 5 hours, and then the degree of retention of the red clay composition in the absorbent cloth was compared with the naked eye.

Evaluation score Evaluation contents Manufacturing Example 1 One The red clay composition separates, generating a large amount of dust, and dissolution of the red clay composition occurs. Production example 2 4 almost no change Production example 3 One The red clay composition falls off in pieces, and although the red clay composition does not dissolve, it cannot function properly.

Manufacturing Example 1 Production example 2 Production example 3 10 minutes A little dust is generated No change Slight loss of red clay pieces occurs 30 minutes A little dust is generated No change A little bit of red clay falls off 1 hours Some dust is generated No change Some pieces of red clay fall off 5 hours Generating large amounts of dust,
Dissolution of red clay composition No change A large amount of red clay pieces fall off, and some dust is generated.

Figure 1 shows the results of confirming whether dust is generated depending on the fabric of the red clay guard absorbent cloth.

As a result, as shown in Tables 3 to 4 and Figure 1, in the case of Preparation Examples 1 and 3, the red clay composition was not completely adsorbed to the absorbent cloth, resulting in dust generation or falling off of red clay pieces. However, in the case of Preparation Example 2, it was confirmed that the red clay composition was completely adsorbed on the absorption cloth.

In other words, the red clay guard according to one embodiment includes polyester and cotton in the same content, so not only is the adhesion of the red clay composition in the absorbent cloth excellent, but it is maintained for a long period of time, thereby reducing the occurrence of defects due to weather such as high temperature and rain after construction. .

Specifically, the red clay guard of Example 1 and the red clay gunny sack of Comparative Example 1 were wrapped around the damaged area of the tree. At this time, the red clay guard was rolled up to the uppermost part where it was to be constructed, and the red clay guard was wrapped so that it overlapped by about 10 to 30%. Afterwards, the red clay guard was fixed using Taka. In addition, the red clay composition of Preparation Example 2 was applied directly to the trees by painting with a brush or using an air extrusion sprayer. Afterwards, it was monitored for 6 months to observe damage and wear.

Figure 2 shows the results of confirming the durability of the red clay guard according to one embodiment.

As a result, as shown in Figure 2, it was confirmed that the state of application on the tree surface was relatively even immediately after installing the red clay guard of Example 1 and the red clay gunny bag of Comparative Example 1. On the other hand, when red clay was applied directly to trees, it was confirmed that the application was uneven depending on the nodes and shape of the trees.

One month after installation, there was no significant change in the installed state of the red clay guard of Example 1 compared to immediately after installation, but it was confirmed that the surface of the red clay guard of Comparative Example 1 was relatively damaged, such as lifting at the installation site. Additionally, when red clay was applied directly to a tree, it was confirmed that the applied red clay began to peel off along the damaged part of the tree.

Six months after installation, the red clay guard of Example 1 did not change in its installed state compared to immediately after installation. However, the red clay sack of Comparative Example 1 was found to have many damaged areas, such as peeling off the installation area, and some parts fell off, requiring additional construction. In addition, when red clay was applied directly to trees, it was confirmed that the applied red clay also fell off as the bark of the trees peeled off.

That is, the red clay guard according to one embodiment is resistant to external damage or abrasion and can be maintained installed for more than 6 months without the need for excessive maintenance or repair.

Check the adhesion of the red clay guard

The adhesion of the red clay guard according to one embodiment was confirmed depending on whether or not the heat compression process was performed. Specifically, the red clay guard of Example 1 and the red clay guard of Comparative Example 2 were installed on a pine specimen. Afterwards, tap water was sprayed for 1 minute at a flow rate of 3 L/min from a distance of 1.5 m, and the attachment state of the red clay guard was checked.

Figure 3 shows the results of confirming the adhesion of the red clay guard according to one embodiment.

As a result, as shown in Figure 3, it was confirmed that the red clay guard of Example 1 was in good adhesion even after water spraying. On the other hand, it was confirmed that the surface of the red clay guard of Comparative Example 2 was peeled to a size of 13 cm wide x 19 cm long.

That is, the red clay guard according to one embodiment is manufactured through a heat compression process, so that the adhesion to the tree surface is improved and the holding power after construction can be increased.

Confirmation of bonding strength according to resin content in red clay composition

The binding force within the red clay guard according to the resin content in the red clay composition according to one embodiment was confirmed. Specifically, the red clay guard of Examples 1 to 5 was wrapped around the damaged area of the tree. At this time, the red clay guard was rolled up to the uppermost part where it was to be constructed, and the red clay guard was wrapped so that it overlapped by about 10 to 30%. Afterwards, the red clay guard was fixed using Taka. 20 days after construction, impact was applied by hand to check whether red clay powder was flying away from the red clay guard.

Figure 4 shows the results of confirming the adsorption capacity of the red clay guard according to one embodiment.

As a result, as shown in Figure 4, it was confirmed that in Examples 1 and 2, no powder flying phenomenon occurred at all, but in Examples 3 and 5, powder flying phenomenon occurred.

That is, the red clay guard according to one embodiment includes a certain amount of resin in the red clay composition, thereby improving the bonding strength with the red clay adsorbent cloth.
