Description

HEAT MELTING MACHINE OF MATERRIAL FOR PREVENTING SLIP OF ROAD}

The present invention relates to a melter of a road surface slipper that can be applied while forming grooves on the road surface.

In general, when snow or rain comes, the road becomes slippery, and thus the risk of traffic accidents tends to increase. In particular, downhill or steep turns, accelerations, crossroads, crosswalks, and roundabouts, etc. The area needs to be prepared for rainy weather slippage.

As a countermeasure against such slippage, a method of applying a non-slip agent to a road surface that provides a frictional resistance when driving a vehicle is widely used. The construction method of the anti-slip agent is generally as follows.

First, there is a method of forming a non-slip layer by applying a thermosetting epoxy resin to the road surface and sprinkled aggregate thereon and then crushed with a roller. However, this construction method, the adhesion of the resin is weakened due to the temperature difference of the road surface according to the change of the season, the coating film is easily peeled off and peeled off, the drying time after construction is long, the vehicle cannot communicate for a considerable time after construction, causing traffic jams. , After the application of epoxy resin and spraying aggregates, there is a problem that the work is complicated.

Second, there is a method of using a thermoplastic resin and mixing the thermoplastic resin and aggregate while heating to 200 ~ 250 ℃ in the non-slip facility site and then transported from the melter to the construction machine and fused on the road. This method is generally good in workability, but the construction time is short within 2 hours, the aggregate distribution is biased, the sliding phenomenon occurs on the plastic resin surface, the construction cost is expensive. In addition, the connection area of the work area is not smooth, partial repair is difficult, and it is impossible to install with uniform thickness and size, and the rubber or wax in the product is burned in the process of high heat, so that smoke and odor are generated. There is a problem.

Therefore, the object of the present invention is to re-melt the road surface slipper in the field, while simplifying the application of the road surface slipper, while improving the slip performance and increasing the drainage effect in the rain, the road slipper to ensure driving safety. In providing a melter.

4 is a state of use of the melter according to an embodiment of the present invention,
Figure 5 is a surface state of the anti-slip agent constructed according to an embodiment of the present invention.

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

The present invention uses the melter (2) to re-melt the anti-slip agent (3) just before applying it to the road surface in the field and adjust the re-melted anti-slip agent (3) to the appropriate temperature to fuse with the road surface At the same time, to form a plurality of grooves (3a) in parallel along the longitudinal or transverse direction.

The anti-slip agent (3) according to the embodiment of the present invention is packaged in a wrap of EVA (ethylene vinyl acetate) material and is configured to melt and use as it is wrapped in a wrap immediately before being applied to a road surface in the field.

Anti-slip agent (3) according to an embodiment of the present invention is 20 to 25wt% modified nylon resin, 20 to 30wt% slug aggregate, aluminum chip 5 to 10wt%, low density polyethylene 1 to 5wt%, microwax 3 to 8wt%, coloring It is comprised including 4-6 wt% of pigments and a special filler as remainder.

As the modified nylon resin in the composition of the anti-slip agent (3), a thermoplastic polyamide resin prepared by condensation of diamine and dimer acid having two or more functional groups may be used. The thermoplastic polyamide resin of the present invention serves as a main raw material for forming a coating film of the slipper 3, and firmly attaches various materials of the slipper 3 to each other.

The modified nylon resin can be used in the range of 20 to 25wt% based on the total weight of the composition. When the modified nylon resin is used at less than 20wt%, the workability is lowered and the coating film is not uniformly applied. Durability may be lowered, and when it exceeds 25wt%, the workability may be diminished and the distribution of slug aggregate in the coating may be uneven.

Slug aggregate in the composition of the anti-slip agent (3) is to be sintered with the aggregate by crushing the slug coming out of the iron melting to 300 ~ 500 micron particles in order to increase the sliding resistance.

Slug aggregate can be used in the range of 20 ~ 30wt% based on the total weight of the composition, when using less than 20wt% there is a problem that the anti-slip effect is lowered, when it exceeds 30wt% workability is diluted Aggregate having a large particle size during application has a problem of causing precipitation under the coating film to lower the slipping effect.

The aluminum chip in the composition of the anti-slip agent (3) can be used as an aluminum chip coated with high brightness, and plays an excellent role in visibility of the driver. The aluminum chip may be used in the range of 5 to 10 wt% based on the total weight of the composition, but when used below 5 wt%, there is a problem of inhibiting the brightness, and when it exceeds 10 wt%, the adhesion of the coating film is inhibited. There is a problem.

Low-density polyethylene (LDPE) in the composition of the anti-slip agent (3) is one of the thermoplastic resins and provides elasticity and flexibility when applying the anti-slip agent (3) to the road surface, and also serves to increase adhesion by penetrating into damaged areas of the road surface. .

Low-density polyethylene can be used in the range of 1 to 5wt% based on the total weight of the composition. When it is used below 1wt%, the elasticity and flexibility of the coating film may not be sufficiently provided, resulting in cracking of the coating film at low temperature, and 5wt%. If the excess exceeds the coating film is excessively used when the temperature rises there may be a problem that the coating is sticky when the pollution caused by the wheels of the car.

The microwax in the composition of the anti-slip agent (3), when melting the anti-slip agent (3), lowers the softening point to facilitate the melting, improve the flow of the paint to improve the application of the coating film of uniform thickness on the road surface It serves to form. In addition, even if the coating film is contaminated after drying due to the rise in the coating film serves to make it easy to wash away from rain.

Microwax may be used in the range of 3 to 8wt% based on the total weight of the composition, but when used in less than 3wt% there may be a problem of lowering the meltability and fouling resistance, if it exceeds 8wt% of the coating film There may be a problem such as the occurrence of cracking due to the strength decrease.

The coloring pigment in the composition of the anti-slip agent (3) serves to give a visual effect of the day by giving a color to the product, it can be used in the range of 4 to 6wt% based on the total weight of the composition. Pigmented pigments are particularly susceptible to temperature and are therefore preferably used for agitation in the field.

The special filler in the composition of the anti-slip agent (3) can be used as the remaining amount in addition to the components as described above, which is improved by increasing the durability of the coating by improving the mechanical properties of the coating formed after the composition is applied to the road and cured. It serves to keep the inhibitor 3 for a long time.

Special fillers are pulverized steelmaking slugs produced during iron melting at 1800 to 2000 ° C into 300 to 500 micron particles. If the amount of the special filler is too small, there may be a problem that the hardness of the coating film is deteriorated. If the coating film is too hard, there is a problem that the flexibility is lowered to inhibit the adhesion.

Now, the method of constructing the road surface using the anti-slip agent 3 as described above will be described.

The antislip agent 3 according to the embodiment of the present invention is heated and remelted in the field, the antislip agent 3 is stirred, the antislip agent 3 is discharged along the road surface, and the antislip agent 3 is fused to the road surface. At the same time as the coating, the grooves 3a are formed on the surface of the anti-slip agent 3 and cured at room temperature.
