Abstract

The invention provides a polypropylene composition for preparing an interval section bar and the interval section bar employing the polypropylene composition. The polypropylene composition provided by the invention comprises polypropylene, a vinyl elastomer, a lubricant, an antioxidant, packing, an ultraviolet adsorbent and a pigment.

Description

technical field [0001] The invention relates to a polypropylene composition for the production of spacer profiles and also to the spacer profiles obtained therefrom. Background technique [0002] In the field of construction, insulating glass has been increasingly widely used due to its good heat and sound insulation functions. At present, insulating glass for buildings generally has two or more layers of insulating glass units, and these glasses are spaced apart from each other inside the insulating glass units to form a hollow state. In order to improve the heat insulation effect, an inert gas is usually filled in the hollow space between the glass. However, in order to achieve low thermal conductivity, the heat transfer at the edge junction of the glass and the spacer frame (ie the junction of the edges of the insulating glass unit) plays a very important role, which determines that the spacer profile must have good thermal insulation. At the same time, due to the high ...
