preparation example Construction

[0023] A preparation method, which is suitable for preparing the above-mentioned silicone sealant for wine liquid, comprising the following steps:

[0024] Step 1, kneading, adding antistatic agent GWA-1200, fumed silica, and hydrogen-containing silicone oil to fluorosilicone rubber in sequence, heat treatment after thorough mixing, and then adding zinc stearate, zinc oxide and 2 , 5-dimethyl-2,5-bis(tert-butylperoxy)hexane was added to the fluorosilicone rubber, fully mixed and left to stand for 24~48h to obtain a rubber compound;

[0025] Step 2, cutting the material, re-milling the mixed rubber and cutting it into strips;

[0026] Step 3, molding and pre-vulcanization, pressing the material strip into the mold for pre-vulcanization and fixing to form a silica gel sheet;

[0027] Step 4, secondary vulcanization, using high temperature to vulcanize the silica gel sheet again;

[0028] Step 5, soaking treatment and detection, soak the silica gel sheet in a certain volume fra...

Embodiment 2

[0041] The body is circular, the radius is 80mm, the thickness is 40mm, the assembly port is square, and the side length is 30mm. The body is made of the following raw materials by weight: 100 parts of fluorosilicone rubber, 3 parts of antistatic agent GWA-1200, gas phase method 30 parts of white carbon black, 5 parts of hydrogen-containing silicone oil, 3 parts of zinc stearate, 5 parts of zinc oxide, and 1 part of 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane. The preparation method comprises the following steps:

Abstract

The invention relates to a special silica gel sealing piece for wine, a preparation method and a sheet filter; the technical scheme includes that the special silica gel sealing piece comprises a body,wherein an assembly port is formed in the center of the body; the body is prepared from the following raw materials in parts by weight: 80-100 parts of fluorinated silicone rubber, 10-30 parts of fumed silica, 0.5-1 part of 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane, 3-5 parts of zinc oxide, 1-3 parts of zinc stearate, 2-5 parts of hydrogen-containing silicone oil and 1-3 parts of an antistaticagent GWA-1200. The invention also discloses a preparation method and a chip filter applying the sealing property of the special silica gel for the wine liquid. The preparation method comprises the following steps: mixing, cutting, compression molding and prevulcanization, secondary vulcanization, soaking treatment and detection. The sealing piece is made of fluorinated silicone rubber resistant to organic solvent corrosion, the product performance and the raw material cost are comprehensively considered, and through soaking treatment and detection, the safety of the sealing piece in wine liquid is effectively improved.

Description

technical field [0001] The invention relates to the technical field of silica gel seals, in particular to a special silica gel seal for wine, a preparation method and a sheet filter. Background technique [0002] Wine brewing equipment, especially the seals used in sheet filters, are related to food safety. Since wine is an organic solvent, the seals made of ordinary rubber will precipitate impurities in the wine, which not only affects the quality of the wine, but also poses a threat to human health. Therefore, wine brewing equipment has a high impact on the seals. food safety requirements. Contents of the invention [0003] Aiming at the problem in the prior art that the seal made of ordinary rubber does not meet the safety requirements of wine brewing, the invention provides a special silicone seal for wine, a preparation method and a sheet filter. [0004] The invention provides the following technical solutions: a special silicone seal for wine, including a body, an...
