The present invention relates to automotive and industrial weather strips using thermoplastic rubber.

Description

The automobile and the industry which use thermoplastic elastomer weatherstrip}

The present invention is made of polypropylene, which is made of TPE (Thermoplastic Elastomer), a thermoplastic rubber that foams weather strips used for industrial or automotive airtightness as completely recyclable and environmentally free water. The present invention relates to an automotive and industrial weather strip using thermoplastic rubber that can reduce the weight of a vehicle by reducing the cost of the product and reducing the weight of the product by providing an eco-friendly weather strip that is 100% recyclable.

Generally, window strip rubber such as tail gate, hood seal, trunk lid, etc. is made of an elastic material and is installed at the roof part when the door is opened or closed. It is used to improve the sealing property between the door and the roof when the door is closed by mitigating and minimizing the shock. It is composed of a cushioning sponge or sponge and solid and sponge and reinforcing solid.

However, such a conventional weather strip is formed of EPDM (Ethylene Propylene Diene Copolymer), so that it is almost impossible to recycle the product, and all the wastes and defects generated during the test production, as well as the wastes of the automobile, are discarded entirely. The use of foam material has become a serious problem of environmental pollution.

In particular, in the case of a weather strip in which the iron core enters the reinforcing core inside the solid, it is difficult to separate the iron core and the rubber and thus the recycling is impossible, which is a serious environmental problem.

The purpose of the present invention is to solve the conventional problems, and to form the weather strip as a thermoplastic rubber TPE (Thermoplastic Elastomer), the sponge part is foamed with water instead of chemical foaming agent that is harmful to the human body and has high environmental pollution. The present invention is to provide automotive and industrial weather strips using thermoplastic rubber, which can be molded as possible polypropylene resin to reduce the weight of the vehicle through cost reduction and weight reduction of the product.

100: weather strip 1: sponge part 2: reinforcement core

3: solid

Hereinafter, the present invention will be described in detail with reference to embodiments of the accompanying drawings.

1 shows a triple weather strip 100 composed of a solid 3 embedded with a sponge 1 and a reinforcing core 2, wherein the sponge 1 of the present invention is a thermoplastic rubber TPE (Thermoplastic Elastomer). The material is molded by a foaming method using water as a material, and the reinforcing core 2 embedded in the solid 3 is formed of a polypropylene resin.

FIG. 2 shows a double weather strip 100 composed of a sponge part 1 and a solid 3, wherein the sponge part 1 is foamed using water as a thermoplastic rubber (TPE) material as described above. Molded by the method.

Figure 3 shows a single weather strip 100 consisting of only a sponge (1) or solid (3), the sponge (1) is a thermoplastic rubber TPE (Thermoplastic Elastomer) material formed by a foaming method using water and solid (3) is simply formed by molding as a thermoplastic elastomer (TPE) material.

In this way, the present invention is formed by molding the sponge (1) and the solid (3) as a thermoplastic rubber TPE, but is molded by the foaming method using water harmless to the human body, so it is harmless to the human body and can be recycled as well. Loss generated during the test production and the entire vehicle strip can be recycled when the vehicle is discarded. The reinforcing core (2) embedded in the solid (3) is also made of recycled polypropylene, so the entire weather strip is recycled. It is possible, harmless to the human body, and environmentally friendly. It is possible to reduce the weight of the vehicle through the light weight of the product, thereby saving fuel and reducing the cost of the product.

In this way, the present invention is formed by foaming method using water as a thermoplastic rubber TPE, which is airtight weather strip for industrial or automobile use, is harmless to human body, can be recycled, and can prevent environmental pollution. Big.

Claims (1)
