Problems solved by technology
However, since this ultra-high molecular weight polyethylene film is made of ultra-high molecular weight polyethylene material, it is extremely difficult to bond with metal materials
At present, how to solve the problem of bonding ultra-high molecular weight polyethylene products and metal materials is a worldwide problem. Technicians from all over the world are working hard to study, but it has not been solved so far. The method of stud and nut connection is still used, and the shortcomings of this method Because of: high labor intensity, low work efficiency, poor connection effect, short service life, and many products cannot be used, resulting in relatively limited application of ultra-high molecular weight polyethylene membranes

Embodiment Construction
[0022] A kind of bonding method of ultra-high molecular weight polyethylene film of the present invention and metal plate, comprises the following steps:
[0023] ①Take the ultra-high molecular weight polyethylene film covered with copolymer primer and cut it into blocks for later use;
[0024] ② Grinding the surface of the board or box made of metal materials into a rough surface;
[0025] ③Heating the rough surface in step ② to 190°C-250°C;
[0026] ④ Attach the block ultra-high molecular weight polyethylene film in step ① to the heated rough surface in step ③ one by one, pressurize the block ultra-high molecular weight polyethylene film to make it closely adhere to the heated metal rough surface Together, the pressing time is until the rough surface of the metal cools down to 50°C-60°C.
[0027] The heating equipment in step 3. of the present invention is an ultra-high frequency induction machine, the frequency of this machine is about 200KHz, and the power is 20-30KW.

Abstract
The invention provides a method for binding an ultra-high molecular weight polyethylene film sheet and a metal board. The method comprises the following steps of: (1) cutting the ultra-high molecular weight polyethylene film sheet coated with a copolymer primer into blocks for later use; (2) grinding a board face made of a metal material or the surface of a box body to be a rough surface; (3) heating the rough surface in the step (2) to a temperature of 190-250 DEG C; and (4) gradually adhering the block-shaped ultra-high molecular weight polyethylene film sheets in the step (1) to the heated rough surface in the step (3) one by one; pressing the block-shaped ultra-high molecular weight polyethylene film sheets, so that the block-shaped ultra-high molecular weight polyethylene film sheets are tightly adhered to the heated metal rough surface; and pressing the block-shaped ultra-high molecular weight polyethylene film sheets until the temperature of the metal rough surface is cooled to a temperature of 50-60 DEG C. With the adoption of the method provided by the invention, the ultra-high molecular weight polyethylene film sheet is tightly adhered to a metal material, so that the service life of a product obtained by binding the ultra-high molecular weight polyethylene film sheet and metal is prolonged, and the application range of the ultra-high molecular weight polyethylene film sheet can be expanded.
Description
technical field [0001] The invention relates to a bonding method, which is a bonding method of an ultra-high molecular weight polyethylene film and a metal plate. Background technique [0002] Because the wear resistance of ultra-high molecular weight polyethylene diaphragm is 4-7 times that of steel, the impact absorption capacity is also much higher than that of steel, and it has extremely high corrosion resistance, and the surface smoothness is basically equivalent to that of ice. Therefore, It can be used to stick on the surface of various fields and products such as mine trucks, coal bunkers, ship shells below the waterline, and submarines, and its application effect is extremely remarkable. But, because this ultra-high molecular weight polyethylene film is made of ultra-high molecular weight polyethylene material, it is extremely difficult to bond with metal materials. At present, how to solve the problem of bonding ultra-high molecular weight polyethylene products a...
