AI Technical Summary

Technical Problem

Existing silicone printing technology suffers from problems such as hot adhesion and cold brittleness, poor printing fastness, and high brittleness. Furthermore, both organosilicon-modified acrylic systems and pure silicone rubber materials have limitations such as poor temperature resistance, poor adhesion, and high cost.

Method used

Using high-solids-content silicone PU resin, and through a specific ratio of raw materials such as 1,4-cyclohexyl diisocyanate, hydrogenated phenylmethane diisocyanate, PTMG, polycaprolactone polyol, and hydroxyl organosilicon, combined with a specialized synthesis process, a silicone PU resin for printing with excellent performance is prepared, which is suitable for screen printing technology.

Benefits of technology

The silicone PU resin for printing exhibits excellent stability, film-forming properties, washability, abrasion resistance, temperature resistance, and elasticity, meeting the requirements of silicone printing processes and reducing wastewater discharge, thus demonstrating environmental friendliness.

Abstract

This invention discloses a silicone PU resin for printing and its preparation method, relating to the field of textile printing technology. The silicone PU resin for printing, by weight, comprises 30-45 parts of 1,4-cyclohexyl diisocyanate, 45-75 parts of hydrogenated phenylmethane diisocyanate, 60-80 parts of PTMG, 30-50 parts of polycaprolactone polyol, 90-110 parts of hydroxyl organosilicon monomer, 4-8 parts of small molecule chain extender, 10-15 parts of hydrophilic chain extender, 7-14 parts of end-capping agent, 8-10 parts of triethylamine, 0.1-0.2 parts of catalyst, 700-1000 parts of acetone, and 180-240 parts of deionized water. The silicone PU resin for printing of this invention is stable, and the product exhibits excellent film-forming properties, three-dimensionality, washability, abrasion resistance, temperature resistance, and elasticity, meeting the process requirements of silicone printing. Furthermore, the synthesis process is environmentally friendly and reduces emissions, showing broad application prospects.
