Abstract

The invention discloses an epoxy resin and polyurethane composite heat transfer printing adhesive. The adhesive is prepared from the following raw materials in parts by weight: 20-25 parts of polyurethane resin (KL-540E), 8-10 parts of E-12 epoxy resin, 10-12 parts of sorbitan fatty acid ester, 5-6 parts of polyglycerol fatty acid ester, 3-5 parts of epoxidized triglyceride, 2-3 parts of epoxy tetrahydrodioctyl phthalate, 5-8 parts of silane coupling agent KH550, 4-6 parts of ethylene glycol, 2-3 parts of tert-butyl peroxybenzoate, 5-8 parts of alkylphenol ethoxylate, 1-2 parts of antioxidant DLTP, 2-3 parts of antioxidant DSTP, 2-3 parts of 1-hydroxyethyl-2-oleic imidazoline, 1-2 parts of HDI tripolymer, 1-2 parts of propane diamine, 35-40 parts of acetone and 60-65 parts of dimethylbenzene. Compared with the prior art, the adhesive has the advantages that the adhesive is firm in bonding and enables the product not to break, shed or yellow easily, and has the effect on improving the product quality. The antioxidants are added in the formula, thus greatly improving the oxidation resistance of the heat transfer pattern and improving the weatherability. 1-hydroxyethyl-2-oleic imidazoline enables the corrosion resistance to be greatly improved.

Description

technical field [0001] The invention relates to a thermal transfer adhesive, which belongs to the field of printing materials. Background technique [0002] Thermal transfer printing is to directly contact the patterned transfer film with the substrate, and the graphic layer on the transfer film is melted and transferred to the substrate. The thermal transfer film includes a carrier layer, a release layer, a protective layer, an ink layer, and an adhesive layer. The coatings are closely related and affect each other. Among them, the bonding layer is the substrate adhesive used to bond the ink information layer and various materials, and must have high adhesion, high temperature resistance, scratch resistance, water resistance, cooking resistance and chemical resistance performance. The quality problem of the thermal transfer adhesive in the prior art leads to unsatisfactory properties such as scratch resistance, adhesion, water resistance and high temperature resistance of...
