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.)

1. The utility model provides a battery protective cover plate for electric automobile which characterized in that: the upper surface of the battery cover plate (1) is coated with a full water foaming polyurethane layer (2).

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.

The water foaming polyurethane layer 2 has strong adhesive force and has the functions of high temperature resistance and fire resistance.

The ODP value of the full-water foaming polyurethane is zero, and the full-water foaming polyurethane is non-toxic and environment-friendly; the adhesive force is strong, and the adhesive strength is 0.65 MPa; the heat conductivity is good, and the heat conductivity coefficient is 27 mW/m.k; the size change rate is 1.0 percent within 48 hours at 120 ℃; the size change rate is less than or equal to 0.2 percent within 48 hours at the temperature of minus 30 ℃.
