Description

Technical Field

[0001] The utility model relates to the technical field of bumpers, and more specifically to an anti-seismic EPP bumper. Background Art

[0002] EPP bumper is made of expanded polypropylene foam plastic, which has the advantages of light weight, good elasticity, shock resistance, compression resistance and high deformation recovery rate. It is widely used in automobiles and is commonly used in bumper core materials, ceilings and door fillings to improve the safety factor. Traditional EPP bumpers have poor shock resistance and energy absorption performance and poor anti-aging and wear resistance when in use, which affects the service life of the EPP bumper. For example, the prior art publication number (CN211166768U) describes an EPP bumper with good shock resistance and energy absorption performance. The EPP lining is used as the inner core of the bumper body, and the expanded polypropylene plastic is used to make the bumper have The EPP bumper has the characteristics of light specific gravity and good elasticity. The surface protection body of the EPP bumper is composed of a protective wax layer and a ceramic fiber layer. The protective wax layer protects the bumper from erosion by light, oxygen and ozone, and improves the anti-aging performance. The ceramic fiber layer enhances the surface wear resistance. Combined with the anti-seismic and compressive properties of the EPP lining, the EPP bumper has good anti-seismic energy absorption performance and excellent anti-aging and wear resistance. Bolts are used as fixing components to fix the bumper on the frame. The rubber block installed by the fixing block provides anti-collision protection on the outer surface of the bumper, and under the extrusion of the rubber block, cooperates with the moisture-proof and dust-proof protection of the waterproof film to improve the tightness of the EPP bumper installation.

[0003] When the above device is in use, a surface protective body of the EPP bumper is formed by a protective wax layer and a ceramic fiber layer. The protective wax layer protects the bumper body from erosion by light, oxygen and ozone, thereby improving the anti-aging performance. The ceramic fiber layer is combined with the anti-seismic and compressive properties of the EPP lining to enhance the surface wear resistance. The EPP bumper has good anti-seismic energy absorption performance and excellent anti-aging and wear resistance. However, when it is in use and the car vibrates, friction is easily generated between the layers of the EPP bumper, thereby reducing its service life and also reducing its installation stability.
