METHOD FOR MANUFACTURING THE ACRYLIC ADHESIVE USED TO PROCESS ROLL SCREEN, WATER-SOLUBLE FLAME-RETARDANT RESIN COMPOSITIONS AND METHOD FOR PRODUCING THEREOF

摘要

PURPOSE: A method for preparing a water-soluble acrylic adhesive for roll screen processing is provided to solve problems on quality defects in screen processing, and to improve mixability and dispersion stability of a flame-retardant resin composition using an improved adhesive. CONSTITUTION: A method for preparing a water-soluble acrylic adhesive for roll screen processing comprises the steps of: (i) preparing pre-emulsion; (ii) preparing a secondary process initiator; (iii) injecting a pre-reaction initiator into a reactor, raising the temperature to 60~65 C, injecting the pre-emulsion at one time to induce pre-reaction, and raising the temperature to be a reaction temperature of 73C~77 C for 20 minutes; (iv) injecting the pre-emulsion and secondary process initiator at the same time; (v) raising the temperature of the reactor to 80 C to perform post reaction and aging process; and (vi) cooling to room temperature to control pH to 6.0~7.0.
