Field of the Invention The present invention relates to a molded article of a vinyl chloride resin mounted on a vehicle such as an automobile, which can prevent squeak noise generated when the molded article is rubbed between glass and a car body, and have an adhesive property and surface discoloration of the molded article.

あった。2. Description of the Related Art Conventionally, weather strips for automobiles are:
A vinyl chloride resin or rubber is used, and the vinyl chloride resin is more frequently used because it has good weather resistance and good moldability. When these weather strips are simply formed, the frictional force with the glass is large, and a large load is applied when the glass is opened and closed, and a squeaking noise is generated. As a method of reducing the frictional force, a method of implanting a pile in a portion of the weather strip that comes into contact with the glass has been adopted. However, two steps of forming and implanting the weather strip are required, which is economically disadvantageous. There is a problem that the pile for flocking becomes dust and deteriorates the working environment.

It causes damage. In order to prevent such unpleasant squeaking noise, several types of synthetic resin are prepared by changing the material, equipped with the actual vehicle, tested in an actual vehicle, and the material is developed and selected by trial and error. Was the current situation.

There is also a method of adding a fatty acid amide to impart lubricity to the surface of the molded article and improving the squealing sound. However, the compounding of the fatty acid amide alone can provide only the same improvement as that of the paraffin wax compounding. Furthermore, when used alone, the surface appearance such as whitening and stickiness of the surface is poor, and the adhesive strength is not sufficient.
