High-thermal-conductivity silica gel embossing roller and preparation method thereof

Abstract

The invention relates to the technical field of rubber rollers, and particularly discloses a high-thermal-conductivity silica gel embossing roller and a preparation method thereof. The high-thermal-conductivity silica gel embossing roller sequentially comprises a roller core, a bonding layer and a silica gel layer from inside to outside, the silica gel layer is prepared from the following raw materials: liquid silica gel, a curing agent, a first heat-conducting filler, a second heat-conducting filler and a pigment. The preparation method of the high-thermal-conductivity silica gel embossing roller comprises the following steps: mixing and grinding raw materials of the silica gel layer to prepare composite liquid silica gel; coating the composite liquid silica gel on an original mold with patterns, and curing at room temperature to obtain a silica gel layer; coating a bonding layer on the silica gel layer to obtain a silica gel sleeve; and sleeving the roller core with the silica gel sleeve, and heating to obtain the high-thermal-conductivity silica gel embossing roller. According to the heat-conducting embossing roller, the liquid silica gel and the two heat-conducting materials are compounded, through the synergistic effect of the liquid silica gel, the two heat-conducting materials and the two heat-conducting materials, the heat conductivity of the silica gel embossing roller is improved, and meanwhile the heat-conducting embossing roller has good heat resistance and abrasion resistance.

Description

Technical field [0001] The present application relates to the field of rubber rollers, and more particularly, it relates to a high thermally conductive silica gel roller and its preparation method thereof. Background technique [0002] The rubber roller is a roller article made of a metal or other material, and the outer rubber is crushed, typically consists of outer gelatin, a hard rubber layer, a metal core, a roll neck, and a vent, which includes a roll core. Sandblasting, adhesive treatment, gelatin molding and surface processing. The rubber roller is mainly used in paper, printing, printing, printing, grain processing, metallurgy, plastic. [0003] When the embossing roller made of the rubber roller and the embossed texture, not only the excellent elasticity and mechanical strength of the rubber roller but also make the beautiful pattern, pattern, pattern; but the thermal conductivity of the embossing roller Poor, short life, only applicable to products that have rough textu...

AI Technical Summary

Problems solved by technology

[0003] When the rubber roller is combined with the embossing texture, the embossing roller not only has the excellent elasticity and mechanical strength of the rubber roller, but also can make beautiful patterns and patterns on various materials; but the thermal conductivity of the embossing roller Poor, short life, and only suitable for making rough textures and products that do not require high appearance textures

[0004] In view of the related technologies mentioned above, the inventor believes that the embossing roller has the problem of poor thermal conductivity, which limits its development and use
