In other words, the elastic packaging material construction process according to the present invention made of the process as described above, first, the bottom surface of the object to be packaged, and then clean the bottom surface such as removing foreign matters (S100). At this time, the bottom surface should be flattened, so that the protruding portion is ground flat with a grinder and the like, and removes foreign substances such as soil, sand and dust, which may lower the adhesive strength of the primer.

Next, after the bottom surface is cleaned as described above (S100), the base surface is sufficiently set and then the baseline to which the primer is applied through a tape or a baffle is set (S110). In this case, it is preferable to take protective measures to prevent contamination of the drainage passage and the surrounding structure.

Then, as described above, the reference line is set and displayed (S110), and then uniformly applied through a roller or an air spray to install a predetermined amount of primer on the lower surface of the reference line (S120). At this time, the primer to be used is to select a primer for concrete or asphalt primer according to the concrete or asphalt.

Next, as described above, after applying the primer on the base surface in the base line (S120), and then mixing and stirring the SBR chip (or EPDM chip), the mixed aggregate and the binder at a predetermined ratio to form an elastic layer composition (S130). . At this time, when the primer applied on the base surface elapses for a long time, the adhesive strength of the elastic layer and the base layer is weakened, so the elastic layer composition should be made before curing of the applied primer is made.

Meanwhile, as described above, the SBR chip (or EPDM chip), the mixed aggregate and the binder are mixed and mixed at a predetermined ratio to form the elastic layer composition (S130), and then the prepared elastic layer composition is laid out before the primer is cured. The surface is repeatedly compressed until the thickness becomes (S140).

Next, as described above, the elastic layer composition is laid before the primer is cured (S140), and then, the dried elastic layer composition is dried, and then a surface absorbent of shock absorption and anti-slip function is applied to the surface (S150). At this time, NOVA products were used as the surface finish.

Then, after drying the elastic layer composition as described above, the surface of the shock absorbing and anti-slip function is applied to the surface (S150) and then sufficiently cured for a predetermined time (S160). At this time, curing time is to be made for 24 to 48 hours depending on the weather conditions such as season, temperature and humidity.

In addition, the elastic packaging layer according to the present invention is excellent in wear resistance and there is almost no change in color can be applied to various spaces.

Referring to each process of configuring the elastic packaging material construction method according to the invention in detail as follows. First, the step (a) constituting the present invention is a process of arranging the bottom surface of the object to be packaged (S100), and the bottom surface clearance process (S100) of this step (a) process is shown in FIG. Flatten the underside of the packaged object and remove any debris.

In the lower surface cleaning process of step (a) as described above, the curing of the lower surface must be confirmed and all foreign matters (weeds, fallen leaves, dust, sand and soil, etc.) that can cause significant defects in construction are removed. In addition, the lower surface must be checked to ensure that there is no inclination and level defect so that it can be paved with a certain design thickness, and if any abnormality occurs, the process should be undertaken after checking the measures in consultation with the supervision and supervisor.

Next, the step (b) constituting the present invention is a step of setting and displaying the reference line (S110), and the step of displaying the baseline setting of the step (b) (S110) is shown in FIG. In step (S100), the bottom surface arranged in order to dry and then set the baseline to be applied through a tape or plywood.

In other words, in the step (b) step (S110) as described above, the base surface is sufficiently dried and then the baseline is set on the portion to which the primer is to be applied using a tape or the like.

Compact the surface repeatedly until

In the elastic layer composition installation process of step (e) step (S140) as described above, the elastic layer composition is laid on the upper surface of the primer in the baseline and then repeatedly selected while spreading the surface to form a flat surface to have a constant thickness. Then, using a constant temperature roller, the surface is repeatedly compressed until a prescribed thickness is applied while applying a constant pressure.

Of course, in the process of installing the elastic layer composition of step (e) process (S140) as described above, the portion that the roller does not reach and the defective portion is completed while correcting with an end roller or a heated trowel. Corners that have a significant effect on aesthetics and breakage at the end of the finish should be curved but constructed so that the vertical plane is as perpendicular to the surface of the elastic layer and the base as possible.

Next, the step (f) constituting the present invention is a process (S150) of applying a surface finish to the upper surface of the installed elastic layer (S150), the surface finish application process of this step (f) process (S150) is shown in Figure 1 And after drying the elastic layer composition installed in step (e) step (S140) as shown in Figure 2 and apply a surface finish of the shock absorbing and anti-slip function to the surface.

As the surface finish used in the application of the surface finish in the step (f) step (S150) as described above, SURFACE products, ULTRA products, CUSHION products, and COMBINATION products were used as the NOVA product line. That is, step (f) step (S150) is a step of applying the SURFACE product to the surface of the dried elastic layer as shown in FIG. 2 through a rubber push rod (S150-1), to the surface of the applied SURFACE product Process of applying ULTRA product 1 ~ 2 times through rubber push rod (S150-2), Process of applying CUSHION product 1 ~ 2 times through rubber push rod to the surface of applied ULTRA product (S150-3) and apply CUSHION The surface finish is applied through the process of applying the COMBINATION product to the surface of the product once or twice through rubber push rod (S150-4).
