Problems solved by technology

[0002] In the field of coatings, the types of coatings, preparation technology and their use have developed rapidly, which play an important role in the corrosion protection of materials, especially metal materials. With the rapid development of the automobile industry and the requirements for energy saving and emission reduction, new energy electric vehicles have been obtained Vigorously promote it, and for new energy electric vehicles, vehicle lightweight is an important technical indicator, and the use of lighter aluminum-magnesium alloys with excellent performance to achieve weight reduction has been recognized and promoted by those skilled in the art However, magnesium-aluminum alloys often generate sparks due to the collision of metal materials, which poses a hidden danger to the safety of the battery. At the same time, if there is flammable gas in the environment, the sparks generated will detonate the flammable gas in the environment and cause losses.
[0003] Therefore, the coatings currently used for new energy vehicles still need to be improved

Embodiment 1

[0039] Coating composition (according to mass percentage): 10% of TH resin, 40% of toughening agent, 3% of functional filler, 10% of common filler, 0.08% of curing agent, and the balance of solvent.

[0040] In order to test the adhesion (cohesive strength) of the coating of this embodiment, two 157 aluminum alloy plates are bonded together with the coating of this embodiment. After curing, they are pulled off with a universal material testing machine, and the breaking strength reaches 63-75kg. / cm 2 , indicating that the coating of the present invention has quite good adhesion on the aluminum alloy surface.

Embodiment 2

[0042] Coating composition (according to mass percentage): 30% of TH resin, 20% of toughening agent, 4% of functional filler, 15% of common filler, 0.09% of curing agent, and the balance of solvent.

[0043] In order to implement the corrosion resistance of the coating of this embodiment, the metal test piece formed with the coating formed by the coating of this embodiment is immersed in normal temperature water for one year, 4h in boiling water, and saturated calcium hydroxide for one year, and the test piece has no change . It shows that the coating formed by the coating of the present application has good anti-corrosion performance.

Embodiment 3

[0045] Coating composition (according to mass percentage): 40% of TH resin, 10% of toughening agent, 5% of functional filler, 20% of common filler, 0.1% of curing agent, and the balance of solvent.

[0046] In order to implement the anti-explosion property (anti-friction spark ability) of the present embodiment coating, detect by the national standard method, wherein, test combustible gas: methane gas mixture, methane concentration 6.3-7.0% (volume ratio); Oxygen concentration 24.5-25.5 % (volume ratio) test projectile instantaneous velocity (220 ± 10) m / s, the matrix material of projectile is 157 aluminum alloy, on 157 aluminum alloy samples, be coated with present embodiment coating three-layer, every interval is 12 hours, coating The total thickness is about 100 μm. The target plate used in the test is A3 steel plate, which has been corroded for more than 42 days outdoors, and the inclination angle between the experimental target plate and the projectile is 45 degrees.

Abstract

The invention provides friction-fire-producing-resistant paint and application thereof. On the basis of the total mass of the friction-fire-producing-resistant paint, the friction-fire-producing-resistant paint is prepared from the following ingredients in percentage by mass: 40 percent to 10 percent of TH resin, 10 percent to 40 percent of toughening agents, 3 percent to 5 percent of functional fillers, 10 percent to 20 percent of general fillers, 0.08 percent to 0.1 percent of curing agents and the balance of first solvents. After being coated on the metal surface, particularly on the easy-fire-catching alloy surface containing aluminum, magnesium and the like, the paint with the composition and the mixture ratio has the advantages that the attaching force is ideal; the formed coating can effectively prevent friction sparks during the mutual collision of the metal; meanwhile, good anti-corrosion and anti-explosion functions are realized.
