Problems solved by technology

Screen printing has problems such as long plate-making time, large process pollution, non-environmental ink materials, poor folding resistance and low precision of patterns; while PET film uses PET substrate for heat transfer coating, which is a disposable product. It is a waste of raw materials and is not environmentally friendly, and the price and cost of PET substrates are relatively high, which has formed certain restrictions on the promotion of heat transfer technology and is difficult to be widely used

Abstract

The invention relates to the technical field of ink-jet printing, in particular to a coating composition for pyrography transfer paper, the pyrography transfer paper and preparation methods of the coating composition and the pyrography transfer paper. The coating composition for the pyrography transfer paper is prepared from the following components in parts by weight: 30 to 40 parts of cation exchange resin, 0.5 to 1 part of a fixing agent, 10 to 30 parts of butadiene and styrene copolymer emulsion, 5 to 10 parts of waterborne polyurethane, 1 to 5 parts of calcium stearate emulsion, 10 to 30 parts of silicon dioxide and 0.5 to 2 parts of polysiloxane. The cation exchange resin, the fixing agent and the waterborne polyurethane in the composition have a synergistic effect, so that the permeation of ink is prevented, and the transfer rate and the image resolution of the pyrograph transfer paper are improved. According to the pyrograph transfer paper, body paper serves as the base material, the ink absorption coating is formed on the surface of the body paper in a coating mode, and compared with a PET film prepared with PET as the base material in the prior art, more cost is saved, and better water resistance and printing performance are achieved.

Description

Technical field [0001] The present invention relates to the field of inkjet printing techniques, and more particularly to coating compositions, heat transfer transfer paper and preparation methods thereof for hot draw transfer paper. Background technique [0002] In recent years, the hot-promoting transfer technology has received extensive attention due to the advantages of simple processing steps, energy saving and environmental protection, and colorful image color. However, there is a certain constability of thermal lifting transfer techniques: as in the molten fabric, the cotton fabric is coking in the molten state, and the hot-rise ink is difficult to bind to the fabric when the non-melting is, so the cotton The fabric cannot be directly transferred, usually, before printing the cotton fabric, it is necessary to prepare the treatment liquid or glue bottom, and then ink inkjet printing, and steam activation after ink jet. Wait for processing; if it is transferred to a hard mat...
