Embodiment 1

[0009] 1. The sublimation transfer coating includes the following components by weight: 90-115 parts of carboxymethyl cellulose sodium, 5-8 parts of inkjet medium adsorbent, 0.5-1.5 parts of defoamer, polyvinyl chloride 0.5-1.5 parts of resin, 800-1000 parts of water.

[0010] 2. The manufacturing method for the thermal sublimation transfer printing coating includes the following steps: A. Add 800-1000 kg of water into 90-115 kg of sodium carboxymethyl cellulose and stir evenly; B. Add 5-8kg of inkjet medium adsorbent to the methylcellulose sodium solution, and stir the mixture evenly; C. Add 0.5-1.5kg of polyvinyl chloride resin to the above-mentioned mixture, and stir evenly.

[0011] 3. The obtained thermal sublimation transfer coating was used in actual production. The test results showed that the drying speed of the ink absorption increased from the original average of 7 to 8 to 10 to 12 meters per hour, and the transfer rate increased from the existing coating to 10 to 1...

Abstract

The invention relates to a coating for heat sublimation transfer printing and a preparation method of the coating. The coating comprises components in parts by weight as follows: 90-115 parts of cellulose sodium carboxymethyl, 5-8 parts of an inkjet medium adsorbent, 0.5-1.5 parts of an antifoaming agent, 0.5-1.5 parts of polyvinyl chloride resin or calcium carbonate and 800-1,000 parts of water. The preparation method of the coating comprises steps as follows: 800-1,000 kg of water is added to 90-115 kg of cellulose sodium carboxymethyl and is uniformly stirred; 5-8 kg of the inkjet medium adsorbent is added to the diluted cellulose sodium carboxymethyl solution, and the mixed solution is uniformly stirred; 0.5-1.5 kg of polyvinyl chloride resin or calcium carbonate is added to the mixed solution, and the mixed solution is uniformly mixed. The coating and the preparation method are adopted, few materials are consumed, the production is simple, and the production cost is directly saved; meanwhile, according to an actual detection result, the drying speed is increased by 25%, the transfer rate is increased from 80% of the average number of existing coatings to 95% or higher, and the consumption of transfer paper is reduced by 20% during transfer printing.
