Abstract

The invention relates to a high-pattern-precision and high-temperature-resistant embossing roller structure and a preparation method thereof. The high-pattern-precision and high-temperature-resistantembossing roller structure comprises a roller body, the surface of the roller body is smooth, a protective layer is arranged on the surface of the roller body, and patterns are arranged on the protective layer; the protective layer is made of one or more of titanium carbide, boron carbide and silicon nitride; the embossing roller is used for glass; the thickness of the protective layer is at least50 microns; and the depth of the patterns is less than or equal to 20 microns. The protective layer is prepared outside the roller body through adoption of a high-speed flame spraying method, and thepatterns are prepared outside the protective layer through adoption of a sand blasting method or a laser engraving method or a knife engraving method or the like. The service life of the roller bodycan be prolonged; and the protective layer can prevent the roller body from being oxidized.

Description

technical field [0001] The invention relates to the technical field of embossing rollers, in particular to a structure and a preparation method of an embossing roller with high pattern precision and high temperature resistance. Background technique [0002] Rolled glass is a glass plate formed by cooling and rolling molten glass through upper and lower rollers. It includes three main varieties: rough rolled glass, patterned glass and wired glass. Embossed glass is when the glass is produced, the lower pressure roller with a pattern faces the glass embossing, and when the molten glass flows through the pressure roller, it is calendered into patterned glass. It is used in lighting doors and windows, decoration and household items of various buildings and structures. Such as offices, conference rooms, bathrooms, toilets, kitchens, toilets and public places, etc. [0003] The calendering process is actually a dynamic heat and cold exchange process. When the molten glass is cal...
