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

In the description of the present invention, the same or similar elements are denoted by the same or similar reference numerals, and a detailed description thereof will be omitted.

1 is a perspective view illustrating a first embodiment of an elastic flooring material installed on a floor requiring elasticity of a land facility, a walkway, a pedestrian path, a bicycle road, a park, and the like according to the present invention. As shown in FIG. 1, the present invention is formed by stacking an upper layer 10 on an upper surface of a lower layer 20.

And the upper layer 10 according to the present invention is a weight ratio of rubber: polyethylene chloride: filler is 30 to 45: 1 to 10: 40 to 50, the lower layer 20 is a weight ratio of recycled rubber: reinforcing agent: softener: foaming agent 45 ~ 60: 20 ~ 30: 5 ~ 15: 1 ~ 10 In the present invention, the top layer 10 serves to provide elasticity as well as to prevent slippage, and the rubber of the top layer serves to provide elasticity of the flooring material.

Here, when the weight ratio of the rubber of the upper layer 10 is less than 30, it may not sufficiently provide the elasticity required for shock absorption.

And when the weight ratio of the rubber of the upper layer 10 exceeds 45, the elasticity is increased, but because the resilience coefficient is increased by that may be unsuitable for the flooring.

The rubber of the upper layer 10 according to the present invention is preferably made of a natural rubber: SBR (Styrene-Butadiene Rubber): weight ratio of recycled rubber is 9-13: 9-13: 12-17.

This is because when the rubber of the upper layer 10 is made of pure natural rubber, durability or mechanical strength may be weakened. Therefore, by adding SBR to the natural rubber in the weight ratio, it is possible to minimize the change in elasticity with temperature. And by adding the recycled rubber in the weight ratio, it is possible to reduce the manufacturing cost while maintaining the elastic effect.

Structural formula of the chloride (Chloricated polyethylene) according to the present invention is [CH ₂ -CHCl-CH ₂ -CH ₂ ] n, and serves to increase the heat resistance. In particular, it is possible to prevent deformation of the flooring material due to heat, and to complement the rubber properties that are vulnerable to the fire of the rubber.

If the weight ratio of polyethylene chloride in the upper layer is less than 1, it may be difficult to expect the effect on heat resistance to fire protection.

And even if the weight ratio of polyethylene chloride exceeds 10, it is because the improvement width of a heat resistant effect is not big.

The filler of the upper layer 10 according to the present invention can improve the mechanical properties of the rubber, and is advantageously included in the weight ratio of 40-50 because it is advantageous in terms of cost reduction. And, the filler may be made of CaCO ₃ (Calcium Carbornate).

When the weight ratio of the filler of the upper layer is less than 40, the cost reduction effect is insignificant, and when the weight ratio exceeds 50, the elasticity of the rubber may be reduced and property degradation may occur.

The lower layer 20 according to the present invention supplements the elasticity of the upper layer 10 and serves to absorb external shocks and transfer them to the ground. And it is preferable that the weight ratio of the rubber of a lower layer is 45-60 recycled rubber.

When the weight ratio of the rubber of the lower layer 20 is less than 45, the effects of shock absorption and elastic replenishment may be insignificant.

And when the weight ratio of the rubber of the lower layer 20 exceeds 60 because the elastic flooring may be too large elasticity.

In addition, in order to reduce manufacturing costs, it is preferable to use regenerated rubber of natural rubber and synthetic rubber, and even if regenerated rubber is used due to the function of the lower layer, there is no significant difference in effect.

The reinforcing agent of the lower layer 20 according to the present invention serves to fix or fix the shape of the elastic flooring during the manufacturing process.

And it is preferable that the weight ratio of the reinforcing agent of the lower layer 20 is 20-30. Because if the weight ratio of the reinforcing agent is less than 20, the maintenance of the shape of the elastic flooring during the manufacturing process may not be smooth, and sufficient strength cannot be maintained. And since the elasticity can be reduced if the weight ratio of the reinforcing agent exceeds 30.

And a reinforcing agent is preferably a mineral powder to the content of SiO ₂ containing 70 to 80% by weight. For example, mica powder having a particle size of 100 to 1000 mesh can be used. In case of mica powder, main component SiO ₂ is 77% by weight, Al ₂ O ₃ 14 weight percent, 5 weight percent K ₂ O, and other components such as CaO.

If the particle size is less than 100 mesh, the coarse particles may not be sufficiently compatible with other components such as rubber, which may cause product defects.

When the particle size exceeds 1000 mesh, the time and cost of powdering increase significantly, while the increase rate of the effect is not large.

SiO ₂ may have a stable nature chemically cleave is not preferable to use a Mohs Hardness of 7 long, powder upset relatively easily, and mica powder is 70 to 80% by weight content of SiO ₂ because it has sufficient strength.

The upper layer 10 of the elastic flooring according to the present invention is composed of a weight ratio of rubber: polyethylene chloride: filler: vulcanizing agent: vulcanization accelerator: 30 ~ 45: 1 ~ 10: 40 ~ 50: 0.1 ~ 1: 1-5, The lower layer 20 may be made of recycled rubber: reinforcing agent: softener: foaming agent: vulcanizing agent: vulcanization accelerator weight ratio of 45 to 60: 20 to 30: 5 to 15: 1 to 10: 0.1 to 1: 1 to 5. . Here, the vulcanizing agent contains sulfur, and the vulcanizing accelerator preferably contains mercaptobenzothiazone.

By adding the vulcanizing agent, the cross-linking is made with each other disulfide bonds play a role of maintaining the elasticity in the environment of the polymer properties, such as cold winter.

When the weight ratio of each of the vulcanizing agents of the upper layer and the lower layer is less than 0.1, the elastic retention effect as described above is insignificant, and the weight ratio does not need to be greater than 1 when compared to the amount of natural rubber added to the upper layer and the lower layer.

It is preferable to further include a vulcanization accelerator to promote the activity of such a vulcanizing agent.

In addition, the upper layer 10 and the lower layer 20 according to the present invention may further add paraphenylenediamine or a known antioxidant as an antioxidant. Anti-aging agent serves to prevent aging due to prolonged use, any one or more may be selected from the group consisting of octylmethoxycinnamate, octylsalicylate, octocrylene, butylmethoxybenzoylmethane and oxybenzone. .

In addition, the top layer 10 may further add dyes / pigments. The dye to the dye may be composed of a color matching the place where the flooring material is installed.

The softener according to the present invention is preferably mineral oil or synthetic oil having a viscosity of 3 ° C. to 10 cSt at a viscosity of SAE (Society of Automotive Engineers). The softener has an effect of contributing to quality improvement by facilitating and dispersing the rubber, reinforcing agent, foaming agent, etc. which are the raw materials of the lower layer.

The blowing agent according to the present invention is preferably made of sodium carbonate (Sodium Carbonate).

Due to the foaming by sodium carbonate, micropores are formed in the lower layer, and the effect of absorbing external shocks by the micropores can be increased.

If the weight ratio of the foaming agent of the lower layer 20 is less than 1 may not be sufficiently formed by the micropores by foaming, if it exceeds 10 may cause structural defects.

1 and 2 are a perspective view and a plan view showing a first embodiment of the elastic flooring is installed on the floor required to elasticity of land facilities, walkways, walkways, bicycle paths, parks, etc. according to the present invention.

As shown in Figure 1 and 2, the upper surface of the upper layer 10 according to the present invention is formed with a groove 11 of a predetermined interval in the longitudinal direction, each formed between the groove 11a and the groove (11b) Preferably, the protrusion 12 is provided with a plurality of non-slip grooves 13 in the width direction.

Because embossing or irregularities on the upper surface of the upper layer 10 may cause a rise in manufacturing cost and complexity of the manufacturing process.

In addition, in the case of embossing or unevenness, since it is formed without directivity, slip prevention in the traveling direction may not be sufficiently performed.

Therefore, the non-slip groove 13 formed in the longitudinal direction and the groove 11 formed in the longitudinal direction, such as the upper layer 10 according to the present invention increases the manufacturing efficiency, as well as the non-slip function embossing It has the advantage of being superior to the unevenness.

B-B 'is a cross-sectional view showing a first embodiment of the elastic flooring is installed on the floor, such as land facilities, walkways, walkways, bicycle paths, parks, etc. are required.

As shown in FIGS. 3 and 4, the lower surface of the lower layer 20 according to the present invention is formed by crossing the horizontal ribs 21 and the vertical ribs 22 with each other, and the horizontal ribs 21 are constantly inclined. It is preferable.

Because the horizontal ribs 21 and the vertical ribs 22 intersect, the space portion 23 formed inward may play a role of buffering or shock absorption. In addition, the horizontal ribs 21 and the vertical ribs 22 form a structurally stable lattice structure.

In addition, it is preferable that the horizontal ribs 21 are configured to be inclined constantly. For example, when the driving direction is A 'to A in FIG. 2, the horizontal ribs 21 are configured to be inclined toward the A' toward the bottom.

When the horizontal rib 21 is inclined as described above, the elastic supply transmitted to the human body in the traveling direction is smoothly performed, thereby improving the exercise performance.

Figure 5 is a rear view of the elastic flooring material is installed on the floor required to elasticity of land facilities, walkways, walkways, bicycle paths, parks, etc. according to the present invention.

As shown in FIG. 5, the horizontal ribs 21 according to the present invention are preferably formed 1.2 to 2.0 times thicker than the vertical ribs 22. This is because the horizontal ribs 21 formed to be inclined are formed to be at least 1.2 times thicker than the vertical ribs so as to form a stable structure. When the horizontal ribs 21 are formed to have a thickness greater than 2.0 times the length of the vertical ribs 22, the space part 23 may be reduced so much that the buffering action may be weakened.
