Description

4482 丨 3 Printed by the Consumer Cooperatives of the Central Procurement Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the Invention (^) The present invention relates to a kind of manufactured article with improved adhesion characteristics for coating materials such as paint. The present invention particularly relates to an article of manufacture containing a coated polyolefin composition having improved resistance to petroleum fluids such as gasoline. Polymer blends can be formed or shaped into lightweight and durable objects, such as automotive parts, toys, and various types of equipment covers. Unfortunately, polymer blends, such as those formed from polyethylene, polypropylene, and rubber, are difficult to handle so that the paint adheres to the surface of the object durable. In cases where the blend is obtained from a < TPO " composition, paint adhesion is of particular importance.

As disclosed in USP 4,480,065; USP 4,412,016 and USP 4,439,573. The TPO composition is a blend of a synthetic rubber and a polyolefin such as polypropylene and polyethylene. Because articles made from TPO compositions have reached acceptance in the automotive industry, such as car body parts, it is important that the paint be fully adhered to the τρ〇 composition to resist petroleum fluids such as gasoline. Objects formed from a TPO blend containing real quality polypropylene exhibit poor adhesion to the coating. Therefore, these compositions need to be treated with an interlayer coating to promote adhesion before applying a coating material such as a paint. Unfortunately, the articles made from the ΤΟ composition are difficult to handle until the paint can stick and resist oil flow to the role of gasoline that would disintegrate interlayer coatings. Many paints do not adhere to TPO compositions, or they peel or flake under normal use, high humidity conditions, or in the presence of fuel or solvents. Various methods have been tried to improve the quality of polypropylene and / or rubber (please read the notes on the back before filling this page)

The polymer blends of the present invention typically have a melt flow rate of at least about 10 and typically printed or greater by a consumer cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. It enables the admixture to be molded into composite objects such as automobile bumpers, bumper covers, and interior and exterior. ^ It is known that paints adhere to polymer blends through the use of adhesion promoters. In conventional polymer blends, crystalline materials such as polypropylene are mixed with ethylene / propylene rubber components. The rubber particles present on the surface of the article molded from this blend can provide sites for adhesion promoter bonding. The surface morphology of the molded objects 2 shows that the rubber particles are "island-like" " spread across the sea, 1 sea-shaped ,, and so on. -9 * This paper size applies to China's national standard (CNS > A4% grid (2! 〇X: 297 mm) δ2 1 3 Α7 ------- B7 5. In the description of the invention (7), the adhesion promoter is bonded to these islands and bridges between adjacent islands. Theoretically, it is believed that in the present invention, the use of both high and low molecular weight ^ 晞, propylene-secondary rubber components can provide enhanced surface morphology, and there are many "islands 2" that adhere to adhesion promoters to provide shorter bridges between islands. This provides more secure bonding to the adhesion promoter, so the surface is more receptive to paint and stronger bonding to it. In addition, these terpolymer rubbers are believed to provide stronger bonding between the adhesion promoter and the rubber It may be due to the enhanced permeability of the trimer.
