specific Embodiment 1

[0016] Specific embodiment one: a kind of preparation method of patterned silica gel coiled material, its steps are:

[0017] (1), the preparation of PC embossed film 6, according to the required pattern, form pattern protrusions on the surface of PC film to form PC embossed film 6;

[0018] (2) Set the PC embossed film 6 on the upper discharge roller 1, install the release film 7 on the lower discharge roller 2, and place the silicone raw material 5 between the PC embossed film 6 and the release film 7;

[0019] (3) According to the thickness of the silicone coil, adjust the distance between the upper calendering roller 3 and the lower calendering roller 4, rotate the upper calendering roller 3 and the lower calendering roller 4, and press the PC embossing film 6 and the release Silica gel material 5 is filled between the membranes 7 to form a primary silica gel coil 8;

[0020] (4) Send the primary silicone coiled material 8 into the oven 9 , and the silicone raw material 5...

Abstract

The invention relates to the field of processing technologies of silica gel coiled materials, in particular to a preparation method of a silica gel coiled material with patterns. According to the preparation method of the silica gel coiled material with the patterns, the preparation method of the silica gel coiled material with the patterns includes the steps that firstly, a PC knurled film is prepared, wherein the patterns protruding upwards are formed on one side face of the PC knurled film; and then, a silica gel raw material is placed between the side, having the patterns, of the PC knurled film and a release film, calendaring and baking vulcanization are conducted, and the silica gel coiled material with the patterns is formed. In addition, the preparation method of the silica gel coiled material with the patterns is scientific and reasonable in step design and easy to operate and learn, the labor intensity and environment pollution are reduced when workers spray the patterns, andthe preparation method is worthy of use and popularization.

Description

technical field [0001] The invention relates to the field of processing technology of silica gel coils, in particular to a preparation method of patterned silica gel coils. Background technique [0002] The calendering process is a necessary process for the production of silicone coils. The traditional calendering process mainly uses solid silica gel to achieve the embossed effect on the surface of the product through rolling or spraying. This method is complex in process, labor-intensive for workers, and serious environmental pollution. [0003] The existing liquid silicone calendering technology usually squeezes the silicone raw material between the upper and lower release films from a fluid state through the mutual extrusion of the rollers, controls the thickness of the product through the calender roller spacing, and completes the silicone raw material through high-temperature baking. Vulcanized, made into a silicone coil, and then sprayed twice and vulcanized at a high ...
