DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inexpensive, vibrant color building gasket.

[0002]

2. Description of the Related Art Referring to FIGS. Conventionally, as shown in FIGS. 1 to 4, an outer wall joint gasket 10 is fitted into a joint formed at a connection portion of an outer wall stretched outside the building as shown in FIGS. Of these, the three types except for FIG. 2 use a polyolefin-based rubber for the base 11 and apply the above molding material together so that the exposed portion 12 seen from the outside is covered with a surface layer 13 such as Hypalon or chlorinated polyethylene having excellent light resistance. Since it is difficult to cope with the demand for colorization that extrudes and produces clear colors, it is difficult to cope with the rubber alone, so that a coating (thickness of 30 to 40 microns) is applied thereon. In FIG. 2, both the base 11 and the exposed portion 12 use, for example, Hypalon or chlorinated polyethylene having excellent light resistance.

However, the above-mentioned conventional exposed portion 12 which is covered with a surface layer 13 such as Hypalon or chlorinated polyethylene which is excellent in light resistance, extruded together, and painted so as to produce a clearer color is expensive and waste material. The use of hypalon and chlorinated polyethylene, which emit harmful chlorine, increases the cost and pollutes the environment during disposal.

[0004]

The problem to be solved is that the above-mentioned conventional building gaskets are expensive and use high-palon or chlorinated polyethylene which emits waste materials and harmful chlorine, so that the cost is high and disposal is difficult. Sometimes polluting the environment.

[0005]

A description will be given with reference to FIGS. 4 to 9. The present invention relates to a gasket to be installed to prevent water from entering the inside of a building, and a base 1 made of polyolefin rubber so that an exposed portion 12 visible from the outside is covered with a tape 14 made of silk-printed polyethylene.
1 and the tape 14 are extruded together and vulcanized.

[0006]

An embodiment of an outer wall joint gasket will be described with reference to FIGS. Describing an embodiment, at the joint formed at the connecting 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. In other words, the exposed portion 12 which is visible from the outside has a molecular weight of 500,00 such as ultra-high molecular weight polyethylene or water-crosslinked polyethylene having a coating film printed thereon.
A base 1 made of polyolefin rubber so as to be covered with a tape 14 made of 0 to 1,000,000 polyethylene.
1 and the tape 14 are extruded together and vulcanized.

Referring to FIG. 9, an embodiment applied to a zipper gasket for a window frame will be described. Zipper gasket 2
Reference numeral 0 denotes a sheet 24 of ultra-high molecular weight polyethylene having a base 21 made of EPDM or the like and a coating film silk-printed on the exposed surface layer 13.
, And both are extruded together and vulcanized.

In terms of the operation, light resistance is good, but the cost is high, and there is no need to use waste materials and chlorinated polyethylene, which emits harmful chlorine, and there is no need for painting. Therefore, manufacturing costs are reduced and environmental pollution is reduced. There is no problem and it can be applied as a building gasket requiring a vivid color.

[0009]

Since the present invention is configured as described above,
The conventional light resistance is good, but the cost is high, it is cheaper, pollution-free, 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.
