Embodiment Construction

[0012] Example figure 1 Shown is first to use a kind of ceramic composite coating of the present invention, wherein the insulating ceramic bottom layer 2 is directly coated on the metal roller core 1 surface as the bottom layer of insulating high-voltage corona, and will additionally be coated with a layer of anti-sticking on it Schematic diagram of the structure of the polymer coating 3.

[0013] The porosity of the insulating ceramic bottom layer 2 of the ceramic composite coating is lower than 2%, and the thickness is greater than 0.5 mm; the thickness of the anti-adhesive polymer top layer 3 of the ceramic composite coating is less than 0.05 mm.

[0014] Compared with the traditional technology, a ceramic composite coating of the present invention, the surface of the metal roller core 1 must be thoroughly cleaned before coating, and the insulating ceramic bottom layer 2 can use thermal spraying, physical evaporation, and chemical evaporation coating methods . Coated on t...

Abstract

The invention relates to a coat which coats the surface of a roller core of a plastic filming-drawing mechanism corona-discharge roller made of metal or other materials. The coat coats the surface of the roller core of the plastic filming-drawing mechanism corona-discharge roller; therefore, the high-voltage corona can be borne on one hand, and a plastic film is prevented from bonding to the surface of adiabatic ceramic materials on the other hand. Compared with the ceramic coat which adopts the traditional technique, the ceramic composite coat of the invention can prevent the plastic film from bonding to the surface of the adiabatic ceramic materials.

Description

technical field [0001] The invention relates to a ceramic composite coating, in particular to a coating coated on the surface of a roller core of a corona roller of a plastic film stretching machine made of metal or other materials. Background technique [0002] In the production of some plastic films, in order to facilitate its compounding and surface printing, etc., it is necessary to use high-voltage corona in the electric field for treatment, and a pair of rollers used to support the film are called corona rollers. Directly bear the action of high voltage corona. The structure of the conventional corona roller is that the metal roller core is covered with a rubber outer layer, and the metal roller core is a hollow structure. The rubber material has excellent corona resistance and is flame retardant without breakdown, but it is easy to fall off after aging. In recent years, insulating ceramic materials have also been used to replace rubber materials on the market to mak...
