Problems solved by technology

[0003] Due to the relatively high hardness of the rubber roller material, cross-sections are often caused by two moldings, and the rubber materials with two hardnesses cannot be well blended. In order to reduce the generation of cross-sections, another way is

Example Embodiment

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0016] The embodiments of the present invention include:

[0017] A molding process for base rollers includes the following steps:

[0018] Mixing of 95 degree rubber: first use an internal mixer for processing, add 100 parts by weight of styrene-butadiene SBR for mastication, add 160 parts by weight of carbon black, 15 parts by weight of naphthenic oil, and 30 parts by weight after plasticizing for 3 minutes High styrene resin, 30 parts by weight of light calcium carbonate and processing aids are mixed, and the processing aids inc

Abstract

The invention discloses a mold-pressing and shaping technology of base rollers. The mold-pressing and shaping technology comprises the following steps: mixing glue stocks of 95 degrees, mixing glue stocks of 80 degrees, performing multiple extrusion, performing mold pressing and shaping, adding extruded and shaped cylindrical glue stocks in a mold pressing machine, and performing mold pressing and shaping for 200-220 seconds at the temperature of about 170 DEG C so as to obtain rubber rollers. Through the manner, the mold-pressing and shaping technology of the base roller, disclosed by the invention, uses a shaping technology of compound materials, firstly composite cylindrical glue stocks are shaped at a time, and then disposable mold pressing and shaping is performed so that the rubber rollers with firm structures are obtained; a yield problem is solved, the operation is more convenient and efficient, and the qualified rate of products is relatively higher; high acryl resins are added, so that the adhesiveness of the glue stocks is improved, the glue stocks have good adhesiveness during multiple extrusion, and the high quality of the cylindrical glue stocks basically avoids the situation that the rubber rollers are broken in surfaces after mold pressing.
