BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to the accompanying drawings.

The present invention provides a rubber composition for a covering film which can prevent the inflow of rainwater into an underground facility such as a parking lot, a subway or the like or a low-lying house when the rainy season or rainy season such as rainy season rains suddenly. .

The rubber composition for a building according to the present invention means a composition having water swelling properties that swells with time when it comes into contact with rainwater or the like.

To this end, the rubber composition of the present invention comprises 1 to 10 parts by weight of stearic acid, 1 to 10 parts by weight of zinc oxide, 100 parts by weight of n-cyclohexylbenzothiazole as a benzothiazole series, 0.1 to 5 parts by weight of a vulcanization accelerator selected as sol-2-sulfenamide (CZ), 10 to 50 parts by weight of carbon black, 0.1 to 10 parts by weight of sulfur and 50 to 300 parts by weight of a polyacrylate water swellable agent.

More preferably, the rubber composition of the present invention comprises 1 to 5 parts by weight of stearic acid, 1 to 5 parts by weight of zinc oxide, 100 parts by weight of N-cyclohexylbenzothiazole-2-sulfenamide as a benzothiazole series, 0.5 to 2 parts by weight of a vulcanization accelerator which is employed as a vulcanization accelerator (CZ), 10 to 30 parts by weight of carbon black, 1 to 3 parts by weight of sulfur and 100 to 250 parts by weight of a polyacrylate water swellable agent.

The rubber is a rubber having a uniform property and a high strength at the time of vulcanization. Normally used natural rubber can be used, and the content ratio of natural rubber is 100 parts by weight, which is a standard of the content of other components.

The above stearic acid and zinc oxide are employed as vulcanization auxiliary agents and have the function of activating the vulcanization accelerator. As with the vulcanization accelerator, those conventionally used in the production of a rubber for a barrier rib can be used without limitation.

Stearic acid and zinc oxide (ZnO) are preferably used in an amount of 1 to 10 parts by weight based on 100 parts by weight of the natural rubber. When the amount is less than 1 part by weight, the vulcanization reaction becomes slow. When the amount is more than 10 parts by weight, .

Examples of the vulcanization accelerator include N-cyclohexylbenzothiazole-2-sulfenamide (CZ), tetramethylthiuram disulfide (TT), N-cyclohexyl-2-benzothiazyl-sulfenamide (CBS) Further, a mixture of two or more of these groups may be used, but it is preferable to use N-cyclohexylbenzothiazole-2-sulfenamide (CZ).

The content of the vulcanization accelerator is preferably 0.1 to 5 parts by weight based on 100 parts by weight of the natural rubber. When the amount of the vulcanization accelerator is less than 0.1 parts by weight, an effective vulcanization system is not formed, A scorch may be generated to cause a process failure and a hardness to be too high.

The carbon black is used as a filler and may be used in an amount of 10 to 50 parts by weight based on 100 parts by weight of the natural rubber. If the content of carbon black is less than 10 parts by weight, the mechanical properties such as durability are deteriorated. The hardness increases too much or the water expansion rate decreases because of the mechanical properties for the degree.

The sulfur is used as a vulcanizing agent for vulcanizing the rubber to cure the rubber by binding sulfur to the natural rubber and to exhibit the mechanical properties of the rubber and is preferably contained in an amount of 0.1 to 10 parts by weight per 100 parts by weight of the natural rubber, When sulfur is used in an amount of less than 0.1 part by weight, improvement in durability of the rubber is deteriorated. When it is used in an amount of more than 10 parts by weight, durability and moldability are too high.

The polyacrylate-based water swellable agent, that is, polyacrylate serves as water swelling for expanding rubber when rainwater or the like touches, and is preferably 50 to 300 parts by weight, more preferably 100 to 250 parts by weight .

Therefore, the natural rubber is sieved for a predetermined time by using a mixer (kneader or kneading roll, etc.), then a certain amount of carbon black and processing aid are added and kneaded for a predetermined time, and then polyacrylate adopted as a water swelling agent is added Kneaded.

Thereafter, additives such as the vulcanization accelerator and vulcanizing agent are mixed and kneaded for a predetermined period of time, and then molded into a water-holding film having a predetermined shape.
