Embodiment Construction

[0028] Such as figure 1 Shown is a metal substrate 3 with thermal spraying anti-sticking and wear-resistant coating, the surface of the metal substrate 3 is provided with a nickel-based alloy coating 2, and the surface of the nickel-based alloy coating 2 is dispersed and bonded with silicon polymerization The material resin layer 1, the silicon polymer resin layer 1 is cured and cross-linked by addition type siloxane resin. The layer thickness of the nickel-based alloy coating 2 is 120 μm, and the surface hardness is HRC50˜HRC60.

[0029] The formulation of the nickel-based alloy coating 2 in this embodiment is as follows: C 0.5-1.1%, Si 3.0-5.5%, B 3.0-4.5%, Cr 15-30%, Fe=5.0%, and the balance is Ni.

[0030] The silicone polymer resin is commercially available from Ningbo Chemical Industry Co., Ltd.: A component: addition type siloxane; B component: composite platinum catalyst.

[0031] The above-mentioned method for the metal substrate with thermal spraying anti-sticking ...

Abstract

The invention relates to anti-sticking wear-resistant treatment of a metal substrate, in particular to a metal substrate with a thermally-sprayed anti-sticking wear-resistant coating and a preparation method thereof as well as a driving roller adopting the substrate. A nickel-based alloy coating is arranged on the surface of the metal substrate with the thermally-sprayed anti-sticking wear-resistant coating, and a silicon polymer resin layer is arranged on the surface of the nickel-based alloy coating in a disperse combination mode. The invention also discloses a method for preparing the metal substrate with the thermally-sprayed anti-sticking wear-resistant coating as well as a driving roller adopting the metal substrate. The product disclosed by the invention has the advantages that the anti-sticking effect is improved, the service life is prolonged, the equipment maintenance and repair strength and period are reduced, the equipment service efficiency is increased, the product quality is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the anti-adhesive and wear-resistant treatment of metal base materials, in particular to a metal base material with a heat-sprayed anti-stick and wear-resistant coating, a preparation method thereof and a driving roller using the base material. Background technique [0002] Applied to coating machines, printing machines, printing and dyeing machines, tape production machinery, diaper production machinery, etc. . The drive rollers of these machines often need to be in contact with the gluing surface, printing surface or printing and dyeing surface. The undried printing surface and printing and dyeing surface are easy to contaminate the roller and affect the surface pattern of the product. At present, "Teflon" is generally used to treat the surface of the roller. Such as Chinese utility model patent (application number: 200720199289.X application date: 2007-12-14) discloses a kind of anti-adhesive foil roller, used in automatic...
