Problems solved by technology

However, the manufacturing efficiency of laser engraving is low, the preparation size of the roller surface is limited, the equipment cost is high, and the equipment, maintenance and manufacturing costs are high; corrosion engraving, engraving depth is shallow, and it is very difficult to realize the micro-nano dual-scale structure control on the surface of the embossing roller. Form a stable micro-nano scale three-dimensional structure, short service life, low product quality, unstable quality, and pollute the environment

preparation example Construction

[0020] In a first aspect, the present invention provides a method for preparing an embossing roll with a micro-nano dual-scale structure on the surface, comprising transferring powder with a micro-nano dual-scale structure to the surface of the embossing roll blank to form micro-nano bi-scale structures by supersonic collision deposition. Nanostructured coating, wherein the roll blank of the embossing roll is made of aluminum alloy.

[0021] The powder with the micro-nano dual-scale structure is a three-dimensional powder with multiple tree-shaped branches on the surface. Due to its special morphology, when it is attached to the surface of the substrate, it can make the surface of the substrate form uneven microscopic. Nanostructure coating, which greatly improves the texture formation and touch texture of leather.

[0022] The invention adopts the supersonic collision deposition technology to directly plant the powder with the micro-nano double-scale structure on the surface ...

Embodiment 1

[0052] This embodiment provides an embossing roll, the roll blank is 6061 aluminum alloy, the powder with micro-nano dual-scale structure is pure nickel powder, and the powder structure is as follows image 3 As shown, its preparation method is as follows:

[0053] S1, roll blank pretreatment

[0054] Use 80-2000 mesh sandpaper to polish the surface of the roll blank in turn. The number of sandpaper meshes for each grinding should be greater than the number of sandpapers for the previous grinding, and the traces of the previous grinding should be removed for each grinding.

[0055] After grinding, use a polishing cloth to polish the surface of the roll blank until the roughness of the roll blank surface is 0.8 μm, to ensure that the powder with the micro-nano dual-scale structure can be completely and uniformly sprayed on the roll blank surface.

[0056] Use acetone to clean the polished roll blank to remove the debris remaining on the surface of the roll blank during the pre...

Abstract

The invention discloses an embossing roller with a micro-nano dual-scale structure on the surface as well as a preparation method and application of the embossing roller, and relates to the technical field of leather manufacturing. Powder with a micro-nano double-scale structure is transferred to the surface of an embossing roller blank in a supersonic speed collision deposition mode, so that one tree-shaped branch on the surface of the powder with the micro-nano double-scale structure is directly inserted into the roller blank, and the micro-nano structure coating is formed. According to the method, the size of the roller surface is not limited, the preparation method is simple, the micron scale and the nano scale of the coating are controllable, the structure is three-dimensional, the texture of leather is greatly improved, and a new scheme is provided for preparing the micro-nano dual-scale structure on the surface of the embossing roller.

Description

technical field [0001] The invention relates to the technical field of leather manufacturing, in particular to an embossing roller with a micro-nano double-scale structure on the surface, a preparation method and application thereof. Background technique [0002] In the contemporary manufacturing industry, the use of artificial leather for the decoration of bags, clothing, shoes, vehicles and furniture has been increasingly recognized by the market, with a wide range of applications, large quantities and varieties. The appearance, texture, physical properties and wearing comfort of artificial leather are all important factors affecting the development of artificial leather. It is the development goal of artificial leather to have the suppleness of real fur and the smooth touch of skin. [0003] The key component of artificial leather preparation The embossing roller is one of the important components that give artificial leather this surface texture. Under the same raw mate...
