Abstract

To employ a snow-melting effect-maintaining non-slip rubber sheet for a vehicle which reduces salt damage caused by calcium chloride spraying in order to address the big problem of snow melting agent spraying methods which while easily being able to remove snow and prevent freezing of a road surface also causes salt damage with the spraying of the snow melting agent; the snow-melting effect-maintaining non-slip rubber sheet for a vehicle has been developed to newly reduce salt damage by improving the calcium chloride agent spraying methods.SOLUTION: A conventional calcium chloride agent was dispersed on a road surface. While there were still remnants of the calcium chloride concentration, they were discharged to the road side ditch simultaneously with snow melt water. As means for solving the problem, a freezing prevention effect can be obtained up to a freezing point of -51°C with a calcium chloride agent having 32% water solubility. Thus, a snow-melting effect-maintaining non-slip rubber sheet for a vehicle is a method for storing the calcium chloride agent in porous holes on the rubber sheet to obtain a snow melting effect over an extended period. The road surface freezing prevention effect can be maintained and the occurrence of salt damage can be reduced.SELECTED DRAWING: Figure 4

Description

The groundwater sprinkling method, the snow melting agent spraying method, the heater mattress installation method, and the like have been implemented for removing snowfall on the road, but all of these methods require enormous maintenance costs. Recently, salt damage has been a problem when snow melting agent is sprayed. Conventionally, even if the snow melting agent is applied to the road, it immediately flows into the side groove of the road and disappears. provide.

Snow melting agents and chloride chloride agents used to remove snow from roads are a global problem due to salt damage. Even in Japan, where snow melting agent is already banned in New Zealand, a method of spraying granular calcium chloride (concentration 32%) with dissolved concentrated salt water has been implemented recently. It is expected that salt damage in the use of snow melting agents will become a more important issue in the Environmental Pollution Control Law.

There is no other way to remove snow and prevent road surface freezes as easily as spraying a snow melting agent. However, spraying snow melting agent has a big problem that salt damage occurs. It is an object of the present invention to develop a technique for reducing salt damage caused by the use of a snow melting agent and a chloride chloride agent. This is a new anti-slip rubber sheet for vehicles with a continuous snow melting effect that reduces salt damage by improving the spraying method of chloride chloride.

As a result of investigating how to use calcium chloride that causes salt damage to solve the problem, it was found that the snowmelt agent and snow melt on the road were flowing into the road ditch at the same time even though the calcium chloride solution concentration was still present. is there. The water solubility of the calcium chloride agent is 32%. The freezing point is -51 ° C, which is a remarkable antifreeze effect. In the experiment, for the purpose of containing calcium chloride liquid on the road surface, when a snow matting agent was added to the fiber mattress and passed through a vehicle with a non-slip chain on it, the fiber mattress broke into a shred and experienced a stunning failure It is. As a new solution, a hard rubber sheet for caterpillar was used, and the results were tested for snow melting effect and road surface freezing prevention effect by accumulating chloride chloride in the hard rubber sheet porous part. A road surface freezing prevention effect was obtained.

The problem is that the calcium chloride agent used to remove snow from the road area generates salt damage. In the present invention, the use of a non-slip rubber sheet for which the snow melting effect lasts, the diluted snow melting solution remaining in the rubber sheet hole exhibits a snow melting effect and an anti-freezing effect for a long time. This greatly contributes to reducing salt damage.

Non-slip rubber sheet (4) with a structure in which a rubber sheet (1) with anti-slip on the back and a porous rubber sheet (3) provided with a snow melting agent reservoir hole (2) are formed through the rubber sheet. The connecting parts of the connected vehicle anti-slip rubber sheet (5) configured by combining the required number are bound with the binding band (6) and laid on sloped roads, parking entrances and other places where anti-slip is required. It is a snow-melting effect continuous vehicle anti-slip rubber sheet characterized by maintaining the snow-melting effect and the road surface freezing prevention effect for a long time.

It is a known fact that snow is melted by applying a calcium chloride agent to the snowy road surface. The novelty of this patent is that the snow-melting effect road surface freezing prevention effect lasts for a long time when the vehicle uses a non-slip rubber sheet for which the snow-melting effect lasts. The sustaining principle is explained below. The water-soluble concentration of granular calcium chloride is 32%, but when a 32% concentration of snow melting agent accumulates in the rubber sheet hole, snow melting melts only at the part where the calcium chloride agent and snow accumulation contact the rubber sheet hole. Snow melting stops when the concentration of calcium chloride solution in the hole reaches 0%. On the other hand, if the calcium chloride agent is spread directly on the road surface,
Even with a 20% diluted solution, it will immediately flow into the road gutter with the melted snow.
Since the freezing point of calcium chloride agent is astonishingly low as −51 ° C., even if it is a 20% concentration liquid, the vehicle anti-slip porous rubber sheet can exhibit not only a snow melting effect and a road surface freezing prevention effect. The above is a description of the principle that the snow melting effect and the freeze prevention effect last.

In winter, the effective period of using a non-slip rubber sheet for vehicles with a snow-melting effect is about 5 months in Japan, but considering the remaining snow road traffic conditions in Tohoku, Hokkaido, There are really big ones. In particular, climbing slope roads, parking lots, sharply curved roads, etc. may become necessary safety items. Overseas, China, South Korea, Russia, and Canada have become automobile societies at the same time as industrial development. Besides being able to export, it can also contribute greatly to the development of SMEs.
