Embodiment 1

[0040] Preparation of carboxyl acrylic resin: 20Kg acrylic monomer, 40Kg isobornyl methacrylate, 10Kg styrene, 13Kg mercaptoethanol and 5Kg benzoyl peroxide are mixed uniformly to prepare a mixed base material. Toluene was injected into the reaction kettle, and the mixed bottom material prepared above was added dropwise when the toluene was heated to reflux. The reaction temperature was 150°C. After refluxing for 3 hours, the solvent was heated to 250°C to remove the solvent and cooled to obtain the carboxyl acrylic resin. The prepared carboxyl acrylic resin was passed through a 160 mesh sieve, and its acid value was determined to be 32.

[0041] Preparation of epoxy acrylic resin: 40Kg of ethyl acrylate monomer, 45Kg of styrene, 10Kg of mercaptoethanol, 3Kg of benzoyl peroxide and 2Kg of tert-butyl peroxybenzoate are mixed uniformly to prepare a mixed base material. Pour xylene into the reaction kettle, and start to add mixed bottom materials when heated to xylene reflux. The re...

Embodiment 2

[0044] Preparation of carboxyl acrylic resin: 25Kg methacrylic monomer, 35Kg lauryl methacrylate, 22Kg styrene, 15Kg thioglycolic acid, 1Kg benzoyl peroxide and 2Kg tert-butyl peroxybenzoate are mixed uniformly to prepare a mixed bottom material. Pour xylene into the reaction kettle, and start to add the mixed bottom material prepared above when heated to xylene reflux. The reaction temperature is 135°C. After refluxing for 3.5 hours, the solvent is heated to 240°C to remove the solvent and cool to obtain the carboxyl group. Acrylic. The prepared carboxyl acrylic resin is passed through a 160 mesh sieve, and its acid value is determined to be 60.

[0045] Preparation of epoxy acrylic resin: 45Kg of glycidyl methacrylate (GMA), 35Kg of styrene, 15Kg of thioglycolic acid and 4Kg of benzoyl peroxide are mixed uniformly to prepare a mixed base material. Toluene was injected into the reaction kettle, and the mixed bottom material was added dropwise when the toluene was heated to ref...

Embodiment 3

[0048] Preparation of carboxyl acrylic resin: 30Kg of acrylic monomer, 30Kg of butyl acrylate, 20Kg of styrene, 10Kg of 3-mercaptopropionate isooctyl ester, and 6Kg of tert-butyl peroxybenzoate are mixed uniformly to prepare a mixed base material. Pour xylene into the reaction kettle, and start to add the above-prepared mixed base material dropwise when the xylene is heated to reflux. The reaction temperature is 130°C. After refluxing for 4 hours, the solvent is heated to 220°C to remove the solvent and cool to obtain carboxyacrylic acid. Resin. The prepared carboxyl acrylic resin was passed through a 160 mesh sieve, and its acid value was determined to be 52.

[0049] Preparation of epoxy acrylic resin: 55Kg of butyl methacrylate monomer, 35Kg of styrene, 6Kg of mercaptoethanol, 6Kg of thioglycolic acid and 3Kg of tert-butyl peroxybenzoate were mixed uniformly to prepare a mixed base material. Inject xylene into the reaction kettle, and start to add mixed bottom materials when ...

Abstract

The invention discloses a heat transfer printing paper detaching agent preparation method which includes the steps: material preparation: grinding carboxyl acrylic resin and epoxy acrylic resin into fine powder and sieving the fine powder by a 160-mesh screen; proportioning: in weight percent, preparing 10-40% of carboxyl acrylic resin, 10-40% of epoxy acrylic resin, 5-30% of white carbon black, 5-30% of amide wax, 5-20% of dodecanedioic acid, 3-15% of organic zinc salt and 10-20% of canola oil into a backing material; mixing: transferring the prepared backing material into a vertical mixing cylinder and mixing the prepared backing material for 10-30 minutes to prepare a heat transfer printing paper detaching agent. The invention further discloses the heat transfer printing paper detachingagent and an application of the heat transfer printing paper detaching agent to the technical field of heat transfer printing. The stability of a heat transfer printing powder coating can be effectively improved by the heat transfer printing paper detaching agent.

Description

Technical field [0001] The present invention relates to the technical field of powder coatings, in particular to a method for preparing a thermal transfer paper release agent. The present invention also relates to a thermal transfer paper release agent prepared by the preparation method of the thermal transfer paper release agent and the thermal transfer paper release agent. The application of paper release agent in the field of thermal transfer technology. Background technique [0002] In recent years, thermal transfer technology has achieved rapid development in the aluminum profile market. Thermal transfer powder coating products are favored by the majority of users for their realistic decorative effects and gorgeous colors. Powder coating heat transfer technology is a special process that sublimates the transfer ink on high-precision paper into the coating at a fixed temperature, so that the profile has a wood-grain texture effect. Thermal transfer powder coating will not c...
