Embodiment 1

[0027] Such as figure 1 Shown, a kind of preparation method of insulating silicone tape, comprises the following steps:

[0028] Step S1. The solid silica gel is put into the calender, and the solid silica gel passes through the rough pressing roller and the fine pressing roller in turn to obtain a silica gel sheet with a width of 500 mm and a thickness of 0.25 mm; and laminate a polyester film on the back of the silica gel sheet;

[0029] Step S2. Send the silica gel sheet with polyester film on the bottom into a high-temperature eight-stage drying tunnel for high-temperature vulcanization, and the drying tunnel performs eight-stage high-temperature vulcanization on the silica gel sheet with polyester film on the bottom; wherein the first high-temperature vulcanization The temperature of the stage is: 130°C; the temperature of the second high-temperature vulcanization stage is: 130°C; the temperature of the third high-temperature vulcanization stage is: 120°C; the temperature...

Embodiment 2

[0036] A preparation method for an insulating silicone tape, comprising the following steps:

[0037] Step S1. The solid silica gel is put into the calender, and the solid silica gel passes through the rough pressing roller and the fine pressing roller in turn to obtain a silica gel sheet with a width of 800 mm and a thickness of 0.8 mm; and laminate a polyester film on the back of the silica gel sheet;

[0038] Step S2. Send the silica gel sheet with polyester film on the bottom into a high-temperature eight-stage drying tunnel for high-temperature vulcanization, and the drying tunnel performs eight-stage high-temperature vulcanization on the silica gel sheet with polyester film on the bottom; wherein the first high-temperature vulcanization The temperature of the stage is: 135°C; the temperature of the second high-temperature vulcanization stage is: 135°C; the temperature of the third high-temperature vulcanization stage is: 125°C; the temperature of the fourth high-temperatu...

Embodiment 3

[0045] A preparation method for an insulating silicone tape, comprising the following steps:

[0046] Step S1. The solid silica gel is put into the calender, and the solid silica gel passes through the rough pressing roller and the fine pressing roller in sequence to obtain a silica gel sheet with a width of 1200 mm and a thickness of 1.5 mm; and laminate a polyester film on the back of the silica gel sheet;

[0047]Step S2. Send the silica gel sheet with polyester film on the bottom into a high-temperature eight-stage drying tunnel for high-temperature vulcanization, and the drying tunnel performs eight-stage high-temperature vulcanization on the silica gel sheet with polyester film on the bottom; wherein the first high-temperature vulcanization The temperature of the stage is: 140°C; the temperature of the second high-temperature vulcanization stage is: 140°C; the temperature of the third high-temperature vulcanization stage is: 130°C; the temperature of the fourth high-tempe...

Abstract

The invention relates to a preparation method of insulated silica gel belts. The method comprises the steps as follows: S1, solid silica gel is placed into a calender and passes through coarse pressing rollers and fine pressing rollers, and a polyester (PE) film is press-fitted on the back surface of an obtained silica gel piece; S2, the silica gel piece is sent into a multi-section type drying tunnel for high-temperature vulcanization, and a vulcanized silica gel piece is obtained; S3, the vulcanized silica gel piece is cooled and then sent into a film coating machine, a PE film is fitted on the front surface of the piece, and the silica gel piece with the PE film fitted on the front surface is obtained; S4, the silica gel piece is sent into a coiling machine for flatness guiding and coiling to form a silica gel coiled material; S5, the silica gel coiled material is sent into a full-automatic cutting table to be cut into multiple semi-finished silica gel belt products; S6, the semi-finished silica gel belt products are placed into a separator for flatness guiding and cutting, and then finished insulated silica gel belt products are obtained through tightening and coiling. The production efficiency is very high; the finished products in different widths can be obtained quickly through cutting by the full-automatic cutting table, and the requirement for quick delivery for small orders can be met; and the semi-finished product inventory pressure can be substantially reduced, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a preparation method of an insulating silicone tape. Background technique [0002] The existing self-adhesive insulating silicone tape is generally produced by the process of extruding silicone rubber compound rubber through an extruder, vulcanizing in the oven, cutting and winding; this method has a product specification that must be realized by opening a pair of molds Production, in addition, there will always be surplus material in the extruder during the production process, resulting in material waste. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing insulating silicone tape. The technical problem to be solved is: a pair of molds must be opened to realize production, and in addition, there will always be surplus material in the extruder during the production process, resulting in material waste. [0004] The technical solution of the present invention to solve t...
