Abstract

The invention discloses anti-sticking soft dope printing adhesive and a preparation method. The adhesive comprises the following raw materials in percentage by mass: 25 to 50 percent of soft monomer, 6 to 20 percent of hard monomer, 0.8 to 5 percent of emulsifying agent, 0.1 to 0.25 percent of initiator, 0.05 to 0.5 percent of buffer, 0.04 to 0.2 percent of thiol and 40 to 65 percent of deionized water. The preparation method comprises the following steps: adding 1 / 8 to 1 / 6 of the soft monomer, the hard monomer and a functional monomer of the raw materials, total emulsifying agent and total deionized water into a reactor, stirring and emulsifying the mixture for 30 to 40 minutes at the room temperature, heating the mixture to between 50 and 65 DEG C, and adding the thiol and the initiator into the reactor; and beginning dripping the mixed monomer, preserving the heat for 2 hours at the temperature of between 50 and 65 DEG C after the dripping is finished, heating the mixture to 70 DEG C, preserving the heat for half an hour, and cooling a product to the room temperature, and discharging the product. The anti-sticking soft dope printing adhesive has the advantages that: the adhesive has excellent washing fastness, super-soft handfeel, environmental protection and no brittleness or after tack, overcomes the defects of hot sticking and poor handfeel of acrylic ester, has many available thickening agent categories, and easily mixes size.

Description

【Technical field】 [0001] The invention relates to the technical field of printing adhesives, in particular to an anti-adhesive soft pigment printing adhesive and a preparation method. 【Background technique】 [0002] Acrylic adhesives have the advantages of weather resistance and fast drying, and are widely used in the textile printing industry, and have gained a large market due to their low prices. Due to the advantages of simple process, resource saving, and less waste water discharge, pigment printing is suitable for the use of fiber fabrics and has been more and more widely used. However, the acrylate adhesive itself has certain defects, which cannot be solved by changing the acrylate components, which affects and limits its further application. The currently used acrylate adhesive has the disadvantage of poor hot-stick feel, which seriously affects the feel of the product when it is applied to printing. [0003] Pigment printing is a printing process that uses adhesiv...
