Abstract
A battery protection cover plate for an electric automobile is characterized in that a full-water foaming polyurethane layer is coated on the upper surface of the battery cover plate. The water-blown polyurethane layer has strong adhesive force and has the functions of high temperature resistance and fire resistance. The invention has the functions of high temperature resistance and fire resistance. If the battery is burnt and is burnt at high temperature and high pressure, the invention can prevent fire, suppress expansion and block heat so as to ensure that the metal cover plate can not be melted at ultra-high temperature and protect the safety of the cabin.
Description
Technical Field
The invention relates to the field of electric automobiles, in particular to a battery protection cover plate for an electric automobile.
Background
The surface of the conventional battery protective cover plate for the electric automobile is not subjected to functionalization treatment and coating treatment.
Disclosure of Invention
The present invention is directed to solving the above problems, and an object of the present invention is to provide a battery protective cover for an electric vehicle.
A battery protection cover plate for an electric automobile is characterized in that a full-water foaming polyurethane layer is coated on the upper surface of the battery cover plate.
The invention has the beneficial effects that:
has the functions of high temperature resistance and fire resistance. If the battery is burnt and is burnt at high temperature and high pressure, the invention can prevent fire, suppress expansion and block heat so as to ensure that the metal cover plate can not be melted at ultra-high temperature and protect the safety of the cabin.
Drawings
Fig. 1 is a perspective view of the present invention.
Fig. 2 is a schematic cross-sectional view of the present invention.
Detailed Description
As shown in fig. 1 and 2, a battery protective cover plate for an electric vehicle is formed by coating a fully water-blown polyurethane layer 2 on the upper surface of a battery cover plate 1.
