Embodiment 1

[0063] Implementation steps:

[0064] (1) Add 3.5 parts by weight of foaming agent (1) and 1.5 parts by weight of vulcanizing agent (A) to 100 parts by weight of silicone rubber, then add 1 part by weight of coloring agent, and knead through a mixer to form a kneaded glue;

[0065] (2) Put the compounded rubber into the open mill for plasticating;

[0066] (3) After plasticizing evenly, put it into a multi-roller calender, adjust the roller distance according to the required thickness, and obtain an unvulcanized silica gel sheet;

[0067] (4) Cover the unvulcanized silica gel sheet with a protective film through a pressure roller machine, and send it into a high-temperature multi-stage tunnel furnace operating at a constant speed, and perform simultaneous foaming and vulcanization in an environment of normal pressure and high temperature to form continuous foaming silicone board. Since the foaming and vulcanization are carried out under normal pressure, there is no need to ...

Embodiment 2

[0080] Add 3.5 parts by weight of blowing agent (1) and 1 part by weight of vulcanizing agent (A) to 100 parts by weight of silicone rubber, then add 1 part by weight of coloring agent, and knead with a mixer to form a rubber compound;

[0081] Other steps are with embodiment 1.

Embodiment 3

[0083] Add 3.5 parts by weight of foaming agent (1) and 2 parts by weight of vulcanizing agent (A) to 100 parts by weight of silicone rubber, then add 1 part by weight of coloring agent, and knead with a mixer to form a rubber compound;

[0084] Other steps are with embodiment 1.

Abstract

The invention discloses a composition for producing a foaming silica gel plate and a production method of the foaming silica gel plate. The composition for producing the foaming silica gel plate comprises the following ingredients by weight: 100 of silicon rubber, 3-4 of foaming agent, 1-2 of vulcanized agent and 1 of colorant, wherein the foaming agent comprises the following ingredients by weight, 100 of azodiisobutyronitrile, 50-80 of methyl vinyl silicone rubber, and 10-30 of vinyl silicon oil, and the vulcanized agent comprises 100 of dibenzoyl peroxide and 50-120 of methyl vinyl silicone rubber. The production method of the foaming silica gel plate comprises the following steps: mixing, calendaring, synchronization foaming under normal pressure and vulcanization, so as to prepare the continuous foaming silica gel plate. Compared with the prior art, the foaming silica gel plate has the advantages of high foaming multiplying power and low density; and the foaming silica gel plate can be continuously produced by adopting the production method of the foaming silica gel plate, and the production method has the advantages of high raw material utilization rate and low labor intensity.

Description

technical field [0001] The invention relates to a composition for producing a foamed silica gel plate and a production method of the foamed silica gel plate. Background technique [0002] Silica gel has the characteristics of organic polymer elastomers, and has the adaptability of inorganic substances to a wide range of high and low temperatures. Silicone products have become the preferred materials for military aerospace, medical, automotive, construction and other fields. The foamed silica gel sheet not only maintains the original excellent properties of silica gel, but also has the characteristics of heat insulation, sound insulation, shock absorption, and light weight. The application field of the foamed silica gel sheet has been greatly extended. The higher the foaming ratio of the silicone plate, the lower its density, the lighter the weight of the product with the same volume, and the better the heat insulation, sound insulation and shock absorption performance.
