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.
