Abstract

In this paper, synthetic polymer EPDM rubber is processed to a certain thickness through vulcanization process, and it is made into a sheet form.The upper part of EPDM Sheet is attached by heat-compressing polystyrene film or by applying adhesive on the film surface, but the lower part of Butyl rubber (IIR) is the main raw material coated with butyl louver made by homogeneous reaction of dots, adhesives and other additives to a certain thickness, and a sheet made by attaching release paper to the lower part of butyl rubber and permanently with EPDM sheet forming strong kitchen water layer. A butyl louver layer that maintains adhesion and elasticity without hardening at all times and has a perfect bond with concrete with solid adhesion to all adherends, and a film layer forming a beautiful surface protection layer. Combined, double and triple waterproofing, flexible waterproof material enables precise construction and simple construction Maintenance is simple, and wishes the junction and the junction between sheets of concrete and registration of utility model fully waterproof sheet.

Description

EPDM Self-Adhesive Rubber Sheet {EPDM BUTYL SHEET}

In this paper, a polystyrene 2-layer non-directional film printed with a logo printed on a EPDM sheet with a thickness of 0.5T or more is heat-pressed or applied with an adhesive, and a butyl rubber with a strong adhesion of 0.5T or more is applied to the bottom of the EPDM sheet. Under butyl is a non-exposed waterproof sheet made of release paper.

As a roof waterproofing product, the improved asphalt sheet, which has been widely used up to now, has a high defect rate and a fire risk, and the construction is significantly reduced. Similar products include a self-adhesive rubber sheet made of polybutylene film coated with butyl louver. This strong butyl makes up about 99% of the material, causing jungle. In summer, wall drooping and polyethylene alone are so weak that it tends to tear on foreign objects or protruding surfaces.

In addition, there was a product with non-woven fabric inserted in butyl, which was used long time ago (Incheon Airport Corporation), but there was a product that was discontinued after construction was stopped due to defects (recently applied for a patent). Butyl and EPDM are elastic. On the other hand, nonwoven fabrics and fiber reinforcements are not elastic, and when pulled, the nonwoven fabrics and fiber reinforcements are damaged, which is a resource source.

EPDM has the disadvantage that it does not remove 100% of the surface bubble phenomenon and it is inactive surface, so there is no other finishing method, so the beauty is not beautiful. The adhesive strength is reduced, and even if the surface bubble is completely processed, the product value is reduced with the black rubber sheet.
In order to secure these shortcomings and to make the waterproofing effect double, the presenter endeavored to attach the film without embossing on the EPDM Sheet and to apply the special primer so that the Butyl is well bonded to the lower part of the EPDM. It is tripled and the aesthetics are also designed to make the foundation beautiful enough without the need for a sheet cut when the logo is printed at 20cm intervals on the beautiful green sheet to see the sheet waterproofing material that was black.
Self-contained construction is safe for workers, simple to install, waterproof, and guaranteed for a long time.

1. How can the most efficient treatment of the adhesion between the lower layer, the adhesion between the sheet layers and the adhesion between the joints between the sheets be achieved in the fantastic combination of EPDM sheet with excellent waterproofness and butyl which realizes both adhesiveness and waterproofness at the same time.
2. How can you finish the black rubber sheet of EPDM to increase the value of the product?

3. Can you improve the constructability and reduce the cost while making the best of both products with the simplest method?

4. Is there any product that is easy to repair because it does not ride in one place when it is cracked or leaks?

5. Beautiful beauty, bright image and good workability

6.The product has no joint lifting or peeling due to the reliable joint treatment.

7.Product that is integral with the sphere by perfect combination with concrete

8. We wanted to devise an economical and inexpensive product, and the Opp Sheet can meet all these requirements.

The present invention is a sheet made by printing a logo printed with green color on the upper part of EPDM sheet with 0.5T or more, coated with Butyl rubber with strong self adhesiveness of 0.5T or more on the lower part of EPDM Sheet, and a release paper on the lower part of butyl. This product is invented to perform more efficient and perfect waterproof work by showing the advantages of waterproofing sheet.

1.Polyethylene non-oriented film

Cross-lamination of polystyrene film in two layers eliminates the directionality and is flexible. The film is made of green color with the elongation rate, stinging, tensile strength, heat and aging resistance. It can be cut without a chair and made to look beautiful. By attaching the polystyrene film to the top using hot pressing or adhesive, it is waterproof by itself, forming the waterproof layer of the sheet once more, and the design and appearance are beautiful, preventing contamination and reinforcing the strength of the sheet.
In addition to the advantage of forming the waterproof layer once more, the embossing process on the EPDM sheet weakens the adhesive strength between sheets, and it is difficult to print without embossing, and the design is inadequate for the product. I wanted to strengthen it.

2.EPDM SHEET
Synthetic polymer EPDM rubber is a waterproof sheet processed to a certain thickness through a vulcanization process, and can be used for non-exposure and exposure. The bottom surface bonded with butyl has a special surface treatment to enhance affinity with butyl rubber compound. EPDM is very resistant to oxygen, ozone and UV radiation in the air.
Since the operating temperature ranges from -50 degrees C to 150 degrees C, there is almost no change in quality even under severe climate change conditions. It is excellent in airtightness against gaseous liquid, and excellent in heat insulation and waterproof function.
3.Butyl rubber adhesive layer
Butyl compound is designed by maximizing affinity with special surface treated EPDM surface and lower extremity by applying homogeneous adhesion and other additives of Butyl rubber (IIR) as the main raw material. The role of and the role of the secondary waterproof layer at the same time. Butyl compound is not taken down at low temperature and does not soften at high temperature. Weather resistance Chemical resistance Ozone resistance is excellent. It has strong adhesion to all kinds of adherends and shows strong resistance to cracking. Butyl compound always maintains adhesion and elasticity without permanent curing.
Butyl compound is perfectly combined with concrete and becomes integral with the sphere so that water does not penetrate the water even if it leaks.
The lower part is attached with release paper so that it is easy to work and move.
These three waterproof materials are layered in three stages, integrated into one sheet, and the three advantages are combined.The waterproofing effect is tripled, and it is more waterproof material that combines construction, waterproofness, protection, aesthetics, workability and economic efficiency.

The waterproofness is sure, but the adhesion between the lower limbs and the sheet-to-sheet connection method is a problem. It solved the surface of EMPDM with the film, freely expressing the value of the product by free expression, waterproofing tripled, simple construction and defect repair, semi-permanent life, beautiful appearance, easy to cut, self-supporting, safe and price It is a low-cost product that can contribute to the development of buildings.The roof of the building, the waterproofing of the upper floor of the underground parking lot, the exterior waterproofing of civil engineering structures, the waterproofing of bridges of railways and road bridges, the waterproofing of tunnels, the landfills of land, the waterproofing of special underground storage facilities, etc. It can be used without being restricted by the scope of use.
