Problems solved by technology

The thermal transfer adhesive currently used in the market is simply composed of ordinary polyvinyl alcohol and additives. After transfer printing at high temperature (150°-180°C), some insoluble glue marks are formed, which makes cleaning difficult and affects the appearance. Due to the traditional transfer printing The surface tension of the glue is small, and it is easy to form a pile of glue on the smooth surface, making the transfer pattern incomplete, and the glue film cannot be removed together with the transfer paper after passing through the high temperature, making it difficult to tear the paper and lowering the passing rate of one-time transfer printing. low, increase production cost

Abstract

The invention discloses a kind of nonwatermark heat transfer glue which is used in heat transfer art for cementing action as well as makes the colour of the transfer paper get through transfer film up to the materials which need transfer. The formulation is: water of 1000 shares, polyvinyl alcohol 0588 of 100-150 shears, polyvinyl pyrrolidon of 20-30 shears, boracic acid of 3-4.5 shears, acrylamide of 30-80 shears, glycerin of 20-50 shears, ammonium peroxodisulfate of 0.05-0.2 shear, sodium acid sulfite of 0.05-0.2 shear, sodium dodecylbenzene sulfonate of 2-4 shears, sorbitan monostearate of 2-4 shears and alkylphenol polyvinyl ether of 2-4 shears. The one-rotation transfer percent of pass is more than 99%. The said nonwatermark heat transfer glue can be coated on anti-theft gates, fireproof doors, iron furniture, filing cabinets, section bars, wooden furniture, ceramics and transfer paper with all kinds of patterns.

Description

technical field [0001] The present invention relates to an adhesive, in particular to an adhesive that is coated on materials such as anti-theft doors, fire doors, iron furniture, file cabinets, profiles, wooden furniture, ceramics, and transfer papers with various patterns. No watermark thermal transfer glue between. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for daily life products and beautification of the environment, so various decorative doors, furniture, cabinets, aluminum alloy products, ceramics, etc. with patterns continue to emerge. The transfer printing paper with various patterns is attached to doors, furniture, cabinets, aluminum alloy products, and ceramics, and ordinary heat transfer adhesives are usually used for bonding and transfer printing. The thermal transfer adhesive currently used in the market is simply composed of ordinary polyvinyl alcohol and additives. After trans...
