The present invention relates to a packaging material and a construction method using waste wool fibers, and more specifically, to wash or crush waste wool fibers generated before and after curing in the process of manufacturing the wood wool board, walkway, sidewalk, bicycle road, landscape The present invention relates to a pavement using waste wood fibers and its construction method, which is used as a main raw material for pavement such as a sex pavement.

Existing sidewalk pavement uses concrete blocks, impermeable products such as colored asphalt and cement concrete, or permeable materials such as pitched asphalt, pitched concrete, and vegetation blocks. However, all of these packaging materials have rigidity and ductility, and there is a problem that impacts both on walking and driving.

Therefore, various products such as rubber blocks and elastic packaging materials using waste tire chips and elastic packaging materials using waste urethane have been developed in order to compensate for these disadvantages and recycle resources.

However, a block using waste tire chips or rubber is composed of a lower support layer in which waste tire chips and aggregates are mixed, and an elastic layer in which pigments are mixed or colored color chips in waste tire chips or rubber. When exposed to the surface temperature of the block sharply rises there was a problem that the elastic layer of the block is separated or lifted off the lower support layer.

In addition, the conventional water-permeable block has a lot of inconvenience, such as filling the void when processing the message, there was a difficulty in using.

In particular, the above-mentioned elastic pavement is most often overlaid on existing pavements (blocks, asphalt, concrete, etc.), so that deformation of the underlying layer is reflected in the elastic pavement as it is, and layer separation from the underlying layer and swelling phenomenon occur. The problem is also pointed out.

Therefore, in order to solve these shortcomings, a composite elastic packaging material and a method of constructing the same are developed.

First, Korean Patent Nos. 441861 and 497253 are permeable elastic packaging materials using waste tires and waste urethane colored rubber chips and construction methods thereof. 6-10 mm fine aggregate (gravel) or silica sand 70-80 on sand or crusher layers. Water permeability consisting of a lower support layer composed mainly of 10-30 parts by weight of waste tire rubber chips crushed to 4 parts by weight and a particle diameter of 4-8 mm, and an elastic layer using waste urethane color rubber chips cut to a length of 3-4 mm on the upper part. The present invention discloses an elastic packaging material and a construction method thereof, and Korean Patent No. 404679 discloses a water-permeable elastic package in which a filter layer, a crushed stone layer, a permeable concrete layer, a waste tire chip layer, and a surface coloring layer are sequentially stacked on a bottom layer (road surface). I've done it.

The permeable elastic pavement as described above has air and rainwater passing through the pavement to suppress swelling and layer separation, and rainwater is permeated into the ground to protect water resources and prevent flooding. It has the advantage of contributing to resource recycling and environmental protection.

However, in the case of the waste tire used in the above, there is a limit to provide a pleasant environment with a smell unique to the rubber lasting a long time, it is difficult to recycle later to form a lower support layer by mixing aggregate and waste tire chips, permeable concrete It was pointed out that when the floor is formed, the curing period is long and the construction period is long.

Therefore, it is environmentally friendly in terms of materials and does not smell unpleasantly smell like rubber, and has excellent elasticity and permeability in terms of function, and paving materials using new paving materials that can be applied to both existing roads and new roads, and their construction. There has been a need for a method.

The waste wool fiber layer of the present invention is divided into two types. The crushed waste wool fiber layer 10 used as the support base layer is composed by mixing 20 to 40 parts by weight of a binder with 100 parts of crushed waste wool fiber, and the used waste wool fiber layer 20 as the surface layer is washed waste wool. It is comprised by mixing 80-120 weight part of binders with 100 weight part of fibers.

Waste wood fiber used in the present invention is obtained by collecting wood board waste generated in the process of producing wood board. These wood wool boards were developed in order to utilize conifers, and they were mainly used for interior construction or sound absorbing materials because they had excellent sound absorption, flame retardancy, and thermal insulation, and no rot corrosion.

Among the two waste wool fibers of the present invention, the pulverized waste wool fibers are pulverized waste wool boards. It is desirable to use it as a strata because it has a lot of weight and is strong.

On the other hand, washed waste wool fibers used for surface layer in landscape packaging is obtained by washing what is generated before curing in the production process of wood wool board. It is light and has the color of wood.

The washed waste hair fibers thus obtained may be dried and used as they are, or may be dyed with natural dyes or the like according to the use or the surrounding environment to impart color or pigments in the process of mixing the washed waste hair fibers and the binder dried during construction. May be mixed with less than 6% of the weight of the waste wool fibers to give a color or use a binder prepared by coloring.

Due to this difference between the pulverized waste wool fibers and the washed waste wool fibers, the content of the binder is varied when the waste wool fibers are used as the main material of the packaging material in the present invention. The content ratio of the pulverized waste wool fibers or the washed waste wool fibers and the binder is found by experiment to determine the ratio that can exhibit the optimum binding force in consideration of the physical properties and the self-weight of the wool fibers, if the amount of the binder is used in the weight ratio range If too little outside, the bonding force is lowered, if too much can be foamed and also economical.
