Abstract

PURPOSE:To reduce cost. by extruding a polyolefin rubber base together with a tape and valcanizing them so as to cover the exposed part visible from the outside with the polyethylene tape on which the film is provided with a silk- print. CONSTITUTION:The polyolefin rubber base 11 is extruded together with a tape 14 and valcanized to form an external wall joint gasket 10 so as to cover the exposed part 12 visible from the outside with a polyethylene tape having molecular weight 500,000-1,000,000 such as extremely high molecular weight polyethylene, water-crosslinked polyethylene, etc., on which the film is provided with a silk-print.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inexpensive and brightly colored building gasket.

[0002]

2. Description of the Related Art An outer wall joint gasket will be described as an example with reference to FIGS. Conventionally, as shown in FIGS. 1 to 4, an outer wall joint gasket 10 is fitted into a joint portion formed at a connection portion of an outer wall stretched outside the building, as shown in FIGS. 1 to 4. Among them, the three types except for FIG. 2 are made of polyolefin-based rubber for the base portion 11, and the molding material is used together so that the exposed portion 12 seen from the outside is covered with the surface layer 13 such as Hypalon or chlorinated polyethylene having excellent light resistance. Since it is difficult to meet the demand for colorization that is extruded and produces a clear color, it is difficult to use only rubber, and therefore a coating (thickness: 30 to 40 microns) is applied thereon. The base 11 and the exposed portion 12 shown in FIG. 2 are made of high-palon, chlorinated polyethylene or the like having excellent light resistance.

However, the conventional exposed portion 12 covered with a surface layer 13 such as Hypalon or chlorinated polyethylene having excellent light resistance, extruded together, and coated so as to give a clearer color is expensive and waste material. In addition, since it uses hypalon or chlorinated polyethylene that emits harmful chlorine, there is a problem that the cost becomes high and the environment is polluted at the time of disposal.

[0004]

The problem to be solved is that the above-mentioned conventional construction gaskets are expensive and use high-palon or chlorinated polyethylene that emits waste materials and harmful chlorine, resulting in high cost and disposal. Sometimes it pollutes the environment.

[0005]

Means for Solving the Problems An explanation will be given with reference to FIGS. The present invention is a gasket to be installed to prevent water from entering the inside of a building, and the exposed portion 12 visible from the outside is covered with a silk-printed tape 14 made of polyethylene so that the base portion 1 made of a polyolefin rubber is used.
1 and the tape 14 are extruded together and vulcanized.

[0006]

EXAMPLE An example of the outer wall joint gasket will be described with reference to FIGS. Explaining the example, in the joint portion formed in the connection portion of the outer wall stretched outside the building,
An outer wall joint gasket 10 is fitted to prevent water from entering the inside of the building. That is, in both cases, the exposed portion 12 visible from the outside has a molecular weight of 500,00 such as ultra-high molecular weight polyethylene and water-crosslinked polyethylene, which are silk-coated with a coating film.
Base 1 made of polyolefin-based rubber as covered by tape 14 made of polyethylene from 0 to 1,000,000
1 and the tape 14 are extruded together and vulcanized.

An embodiment applied to a window frame zipper gasket will be described with reference to FIG. Zipper gasket 2
0 is an ultra high molecular weight polyethylene sheet 24 having EPDM or the like on the base portion 21 and a coating film silk-printed on the exposed surface layer 13.
It is manufactured by extruding and vulcanizing both of them.

Explaining the operation, it has good light resistance, but is high in cost, does not use waste material and hypalon or chlorinated polyethylene which emits harmful chlorine, and does not require coating, so that the manufacturing cost is reduced and environmental pollution is reduced. There is no problem and it can be applied as a building gasket that requires vivid colors.

[0009]

Since the present invention is constructed as described above,
Conventional light resistance is good, but the cost is high, and it is cheaper, non-polluting, and does not require painting compared to those using high-palon or chlorinated polyethylene that emits waste materials and harmful chlorine,
It is useful as a building gasket that requires vivid colors.
