Embodiment 1

[0021] This embodiment provides an adhesive transfer material. The adhesive transfer material is transferred using a galvanized iron drum. The inner wall of the galvanized iron drum is provided with a drum film. The drum film uses a plastic film as a base material and is coated with a release agent on the surface. The release agent is composed of the following raw materials in parts by weight: 10 parts of methyl vinyl silicone oil, 5 parts of ethyl hydrogen-containing silicone oil, 1 part of platinum catalyst and 84 parts of butanone.

[0022] The preparation method of above-mentioned release agent comprises the steps:

[0023] (1) First, add 15 parts of diphenyldimethoxysilane, 5 parts of octamethylcyclotetrasiloxane, 0.5 A mixture of 1 part of dimethylvinylethoxysilane, 0.5 parts of concentrated sulfuric acid and 15 parts of toluene was stirred at 30-45°C for 1 hour, and then 5 parts of deionized water was added dropwise within 1-2 hours at 35-50°C. After the addition was c...

Embodiment 2

[0027] The release agent is composed of the following raw materials in parts by weight: 20 parts of methyl vinyl silicone oil, 7 parts of ethyl hydrogen-containing silicone oil, 3 parts of catalyst and 70 parts of diluent.

[0028] The preparation method of this release agent comprises the following steps:

[0029] (1) First, add 20 parts of diphenyldimethoxysilane, 8 parts of octamethylcyclotetrasiloxane, 0.8 A mixture of 1 part of dimethylvinylethoxysilane, 3 parts of concentrated sulfuric acid and 20 parts of toluene, stirred at 30-45°C for 1h, then added dropwise 5 parts of deionized water within 1-2h at 35-50°C, dropwise After the addition was completed, the temperature was raised to reflux for 4 hours, and the hydrolysis and condensation reaction was carried out to obtain a hydrolysis mixture; the hydrolysis mixture was left to cool to room temperature, then the organic layer was separated and washed with deionized water to neutrality, and then 5 parts of Potassium hydr...

Embodiment 3

[0033] The release agent is composed of the following raw materials in parts by weight: 30 parts of methyl vinyl silicone oil, 10 parts of ethyl hydrogen-containing silicone oil, 5 parts of catalyst and 90 parts of diluent.

[0034] The preparation method of this release agent comprises the following steps:

[0035](1) First, add 25 parts of diphenyldimethoxysilane, 12 parts of octamethylcyclotetrasiloxane, 1 A mixture of 1 part of dimethylvinylethoxysilane, 5 parts of concentrated sulfuric acid and 25 parts of toluene was stirred at 30-45°C for 1 hour, and then 15 parts of deionized water was added dropwise at 35-50°C within 1-2 hours. After the addition was completed, the temperature was raised to reflux for 4 hours, and the hydrolysis and condensation reaction was carried out to obtain a hydrolysis mixture; the hydrolysis mixture was left to cool to room temperature, then the organic layer was separated and washed with deionized water to neutrality, and then 6 parts of Pot...

Abstract

The invention discloses a method for preparing a release agent material for transferring an adhesive, which comprises the following steps: respectively preparing methyl vinyl silicone oil and ethyl hydrogen-containing silicone oil, then adding the methyl vinyl silicone oil, the ethyl hydrogen-containing silicone oil, a catalyst and a diluent into a reaction kettle, conducting heating to 130-150 DEG C, and conducting reacting for 50-70 seconds to obtain the release agent material. A barrel film with a corresponding size is prepared through a release material with the surface coated with a release agent by taking a plastic film as a base material, the barrel film plays an isolation role in the transfer barrel, the utilization rate of an adhesive product is increased, chemical product residues of the adhesive product are reduced, the problem of chemical cleaning of a transfer barrel is solved, and the utilization rate of the transfer barrel is increased.

Description

technical field [0001] The invention belongs to the field of release agent preparation, in particular to a method for preparing a release agent material for adhesive transfer. Background technique [0002] The release agent is to prevent the formed composite product from sticking to the mold, and a type of isolation film is applied between the product and the mold, so that the product can be easily released from the mold, while ensuring the surface quality of the product and the mold are intact. The release agent is divided into two types: internal lubricity and external lubricity. The former is mainly to improve the lubricity of the polymer molecule itself, which requires a certain degree of affinity or compatibility with the resin polymer. The latter is to improve the lubricity between the mold and the polymer. [0003] Existing adhesives, paints, resins, viscous materials, etc. are transported in large quantities, all in plastic tonnage barrels or galvanized iron barrel...
