Problems solved by technology

[0006] The method of hot stamping for cloth in the prior art is: print the bronzing paste on the cloth with a 33T screen, print it at least twice, and then bake it at about 100-150°C for 5-10 minutes, then bronzing, and hot at 180°C; Ironing above 150℃, time 15-25 seconds (16μm thick hot stamping paper, if it is domestic 12μm, the temperature and time can be lowered appropriately), pressure above 4kg / cm, the process is complicated, the process requirements are high, and the cost is high

Embodiment 1

[0039] Mix and stir the raw materials according to the following mass ratio, 350 grams of base glue, including 245 grams of bronzing glue, 105 grams of special glue, 254 grams of epoxy resin, 40 grams of water-based nitrocellulose, 5.5 grams of anti-sticking agent and 350 grams of methyl ethyl ketone, forming Hot stamping glue; apply the hot stamping glue in step 1 evenly on the flower roller; prepare some hot stamping film paper, make the hot stamping film paper pass through the flower roller after step 1; pass the hot stamping film paper after step 3 through 75 degree of oven for 20 seconds, and then laminated with the base cloth and then pass through the hot stamping roller, the temperature of the hot stamping roller is 126 degrees Celsius, and the passing speed is 30 m / min; after air drying, the hot stamping film paper and the base cloth are torn off.

Embodiment 2

[0041] Mix and stir the raw materials according to the following mass ratio, base glue 330, including 231 grams of bronzing glue, 99 grams of special glue, 224 grams of polyurethane resin, 100 grams of oily nitrocellulose, 15 grams of anti-sticking agent and 330 grams of methyl ethyl ketone to form bronzing glue solution; apply the bronzing glue solution in step 1 evenly on the pattern roller; prepare some bronzing film paper, and make the bronzing film paper pass through the pattern roller after step 1; pass the bronzing film paper after step 3 through a 79-degree Oven for 20 seconds, then laminated with the base cloth and pass through the hot stamping roller, the temperature of the hot stamping roller is 146 degrees Celsius, and the passing speed is 30 m / min; after air drying, the hot stamping film paper and the base cloth are torn off.

Abstract

The present invention discloses a gilding glue liquid, which comprises, by mass, 31%-34% of a base glue, 16-25% of a curing agent, 3-10% of a brightener, 0.5-1.5% of an antisticking agent, and 25-35% of a diluent agent. According to the present invention, the original way of coating the gilding glue liquid on the chamois is changed into the way of coating the gilding glue liquid on the back surface of the gliding film paper so as to eliminate the two screen printing processes, and the transfer printing technology is used, such that the technical effect after the gliding and the effect of the technology of the two screen printing and the gilding are the same, the production cost is reduced, and the product speed is accelerated.

Description

technical field [0001] The invention relates to the field of bronzing, in particular to a bronzing glue and a bronzing method using the same. Background technique [0002] Hot stamping glue is metal foil printing adhesive, commonly known as hot stamping glue, which is a special adhesive and the key to the success of metal foil printing. It consists of suitable hot melt adhesives and bonding resins. A special adhesive consists of two components: [0003] 1. There are polyamide series, polyester series, polyethylene series, polyurethane series hot melt adhesives, etc. [0004] 2. Adhesive resins (adhesives) include PA series (containing acrylonitrile) and PU series. [0005] The above two parts are reasonably compounded to form a special adhesive, which is required for metal foil printing. The printed paste has good penetration and movement performance, and can obtain a uniform coating on the cloth surface, and can penetrate into the base cloth properly without excessive pen...
