である。(Prior art) Ultra-high molecular weight polyethylene resin has a significantly larger molecular weight than general high-density polyethylene resin, and has various properties such as slipperiness, impact resistance, soap resistance, cold resistance, and chemical resistance. Due to its excellent characteristics, it is used in general machinery, chemical industry,
It is used in many fields such as transportation and conveyance equipment. For example, in powder transportation and storage equipment, the surfaces of hoppers, chutes, etc. are lined with ultra-high molecular weight polyethylene resin sheets in order to prevent wear and blockage phenomena. In this case, since it is difficult to adhere the metal and the ultra-high molecular weight polyethylene resin, it is common to attach the resin sheet to the metal surface using mechanical joining means such as bolts.

関するものである。(Means for Solving the Problems) That is, the present invention involves sandwiching an adhesive between an ultra-high molecular weight polyethylene resin and a metal, on which adhesive inclusions have been pressed or adhered to surfaces to be joined in advance, and then applying pressure. The present invention relates to a method of joining ultra-high molecular weight polyethylene resin and metal, which is characterized by adhesion.

However, as a result of various tests, it was discovered that a very large adhesive force could be obtained if a suitable adhesive inclusion was crimped or bonded in advance and then bonded to a metal surface, and this led to the present invention. It was.

As the adhesive inclusion, glass cloth, glass fiber continuous mat (glass fibers spread like fluff), vinyl chloride sheet, etc. are used.

当である。An adhesive is sandwiched between the ultra-high molecular weight polyethylene resin whose surfaces to be joined have been treated in this way and the metal, and pressure is applied to join them. It goes without saying that the pressurization may be performed simply at room temperature, but it is also possible to use a combination of heating and pressure. However, heating deforms the ultra-high molecular weight polyethylene resin,
It is inappropriate to have a temperature that would cause melting, deterioration, damage, etc.
