A heat-resistant thermal transfer paper

Abstract

The invention belongs to the technical field of thermal transfer, and discloses high-temperature-resistant thermal transfer paper. The thermal transfer paper is composed of a substrate and a high-temperature-resistant coating which coats the substrate, and the high-temperature-resistant coating is prepared by coating the surface of the substrate by a high-temperature-resistant coating liquid and performing drying; and the high-temperature-resistant coating is prepared from porous starch, modified bentonite, modified diatomaceous earth, polyvinyl alcohol, gas-phase nano silicon dioxide, nano titanium dioxide, fructose, dodecyl dimethyl benzyl ammonium chloride and water, wherein the modified bentonite is prepared from bentonite, a potassium acetate solution, sulfonated cellulose, a silane coupling agent and water, and the modified diatomaceous earth is prepared from diatomaceous earth, sodium lignosulfonate, a silane coupling agent and water. The high-temperature-resistant thermal transfer paper provided by the invention has good high-temperature resistance, and the advantages of good printing quality, a fast drying speed, stable storage and the like; and meanwhile the thermal transfer paper has high thermal transfer efficiency, and a prepared thermal transfer pattern has the advantages of clear and saturated texture, high color fastness and the like.

Description

technical field [0001] The invention relates to the technical field of heat transfer printing, in particular to a heat-resistant heat transfer paper. Background technique [0002] Thermal transfer printing technology is an emerging printing and dyeing technology, which belongs to anhydrous printing and dyeing technology, which can reduce printing and dyeing sewage pollution; thermal transfer paper is a transfer carrier used for printing polyester-containing fabrics or related materials. The ink made of thermal transfer dye prints the desired pattern on the thermal transfer paper through the printer, and then attaches the printing surface of the thermal transfer paper to the fabric or material to be printed and heats it to above 200°C. The dye in the thermal transfer paper is sublimated to the fabric or material by heat to realize the transfer printing and dyeing of the pattern; however, the surface drying speed of the existing thermal transfer paper is slow, and the toleranc...

Problems solved by technology

[0002] Thermal transfer printing technology is an emerging printing and dyeing technology, which belongs to anhydrous printing and dyeing technology, which can reduce printing and dyeing sewage pollution; thermal transfer paper is a transfer carrier used for printing polyester-containing fabrics or related materials. The ink made of thermal transfer dye prints the desired pattern on the thermal transfer paper through the printer, and then attaches the printing surface of the thermal transfer paper to the fabric or material to be printed and heats it to above 200°C. The dye in the thermal transfer paper is sublimated to the fabric or material by heat to realize the transfer printing and dyeing of the pattern; however, the surface drying speed of the existing thermal transfer paper is slow, and the tolerance to high temperature is poor. Due to these problems, the quality of the thermal transfer paper is often Poor and inefficient thermal transfer printing
