Abstract

The cross section of a corner protection part used for a wall is in an L shape. The core part of the corner protection part is made of particle-reinforced foamed aluminium composite materials and wrapped by an elastic material layer. An aluminium alloy shell serves as the elastic material layer. The outer surface of the aluminium alloy shell is coated with organic paint. Sufficient foaming is conducted on aluminium alloy through foaming agent reinforced and composited through silicon carbide and / or aluminium oxide particles, and the particle-reinforced foamed aluminium composite materials are obtained. By means of the foaming base material aluminium-based alloy, it is better ensured that products have a better impact-resistant effect, and meanwhile the product mass is reduced.

Description

technical field [0001] The invention relates to a corner protector for walls and belongs to the technical field of home decoration accessories. Background technique [0002] The parking lot is an indoor column or the protruding part of the passage must be equipped with corner guards. Installing anti-collision strips in the parking lot can prevent vehicles and other vehicles from hitting buildings during driving and turning, or rubbing or colliding with pillars, scratching or bruising car paint and pillars. Even if the driver's negligence causes vehicles and buildings to collide, it can also reduce the degree of damage. It is used in underground parking garages, factory workshops, loading and unloading platforms, both sides of home garage doors, etc. It can not only protect corners or pillars, but also protect cars. It is suitable for use in parking lots, residential areas, toll passages, and underground parking garages. In the prior art, the production cost of the corner g...
