Embodiment 1

[0051] Accurately weigh 3kg of ethyl acetate and 6kg of butanone into a 20L reactor, then add 1.8kg of polyamide, 2.25kg of polyvinyl butyral, 1.2kg of acrylic resin, 0.3kg of vinyl acetate resin, and 0.45kg of 3085 petroleum resin . Heat to 70°C, stir at 300r / min, and keep warm for 6h. After cooling, the adhesive resin is obtained.

Embodiment 2

[0053] Accurately weigh 3kg of ethyl acetate and 6kg of butanone into a 20L reactor, then add 1.95kg of polyamide, 1.5kg of polyvinyl formal, 1.8kg of acrylic resin, 0.3kg of vinyl acetate resin, and 0.45kg of rosin pentaerythritol ester. Heat to 55°C, stir at 100r / min, and keep warm for 8h. After cooling, the adhesive resin is obtained.

Embodiment 3

[0055] Accurately weigh 3kg of ethyl acetate and 6kg of butanone into a 20L reactor, then add 1.5kg of polyamide, 1.95kg of polyvinyl butyral, 1.8kg of acrylic resin, 0.3kg of vinyl acetate resin, and 0.45kg of rosin glyceride . Heat to 60°C, stir at 200r / min, and keep warm for 4h. After cooling, the adhesive resin is obtained.

[0056]The hot-melt adhesives prepared in Examples 1 to 3 were used for thermal transfer hot stamping of sulfuric acid paper respectively. The surface has good permeability and high adhesion to sulfuric acid paper, which makes the hot stamping pattern integrity, slitting and adhesion good.

Abstract

The invention discloses a hot-melt adhesive for parchment paper heat-transfer hot stamping and a preparation method thereof. The hot-melt adhesive is prepared from the following raw materials in percentage by weight: 5-15% of ester-soluble polyamide, 8-15% of polyvinyl acetal, 5-15% of acrylic resin, 1-3% of vinyl chloride-vinyl acetate resin, 2-4% of tackifying resin and 59-79% of solvent. The hot-melt adhesive is mainly used for parchment paper heat-transfer hot stamping, and the pattern obtained by hot stamping has favorable completeness, cutting property and adhesive force.

Description

technical field [0001] The invention relates to the field of polymer adhesives, and mainly relates to a hot-melt adhesive used for thermal transfer hot stamping of sulfuric acid paper and a preparation method. Background technique [0002] At present, a large amount of sulfuric acid paper is widely used in the field of packaging and printing. Sulfuric acid paper is made of fine plant fibers interwoven with each other. In a wet state, it undergoes free beating, no sizing, no fillers, and papermaking. It is soaked in 72% concentrated sulfuric acid for 2 to 3 seconds, washed with clean water, treated with glycerin, and dried. Forms a hard film-like substance. Sulfuric acid paper is solid, dense and slightly transparent. It has the characteristics of strong resistance to oil and water penetration, airtight, and high wet strength. It can be waterproof, moisture-proof, oil-proof, sterilized and disinfected. But it is precisely because of its dense surface and solid texture that ...
