Method for making ultrahigh molecular weight polyethylene board adhere to steel plate surface

Abstract

The invention discloses a method for making an ultrahigh molecular weight polyethylene board adhere to a steel plate surface. The method has the advantages that the workload of maintaining and removing attachment can be greatly reduced, acid and alkali cleaning or mechanical cleaning is not needed, only a high-pressure water gun is needed to flush. The surface of a walking device in water is madeof steel plates to which the ultrahigh molecular weight polyethylene board is adhere has high abrasive resistance and high impact resistance and has effect of absorbing impact energy, the seawater corrosion resistance is strengthened, and the service life of the walking device in water is prolonged. In addition, the ultrahigh molecular weight polyethylene board with the size greater than 2 millimeters has better properties such as radioactivity isolation, nuclear radiation isolation, microwave penetrating resistance and the like.

Description

technical field [0001] The invention relates to a steel plate coating method, which is a method for sticking an ultra-high molecular weight polyethylene plate on the surface of a steel plate. Background technique [0002] The non-metallic material coated on the surface of the steel plate has the functions of anti-corrosion and so on. In particular, underwater vehicles such as large ships and warships require properties such as non-fouling, non-adhesion, corrosion resistance, and impact resistance on the surface to increase their service life and reduce water travel resistance. At present, the method for improving the finish of the metal surface of the shell of the underwater walker is mainly to solve the above problems by using high-performance metal materials. However, the disadvantage of this solution is that it is expensive, and it is relatively difficult to increase the service life to a level corresponding to the cost. The disclosed bonding method between the ultra-hi...

Problems solved by technology

However, the disadvantage of this solution is that it is expensive, and it is relatively difficult to increase the service life to a corresponding level with the cost.

The disclosed bonding method between the ultra-high molecular weight polyethylene film and the metal plate is a relatively good method at present. The maximum thickness of the film used in this method is 1.5 mm. When it is greater than 1.5 mm, it cannot be pasted on the Purpose on the plate

At the same time, in use, it is found that there are deficiencies that are difficult to achieve, such as heating the steel plate in a large area, and then cooling it quickly after coating the diaphragm (if it is not cooled, the diaphragm will be deformed), it is difficult to achieve in the process. The second is the combination of the two materials. The difference in thermal expansion coefficient is large, and it will change when it is cold or hot, which will affect the firmness of the coating and be prone to peeling off. This method cannot be used for the coating of the metal surface of the underwater walker
