Abstract

The invention discloses glue for a sticky mat film. The glue is prepared from raw materials as follows: a component A: soft water, baking soda, an initiator, an emulsifier, iso-octyl acrylate, butyl acrylate, methyl methacrylate, hydroxyethyl acrylate, acrylic acid, starch, caustic soda flakes, dichloromethane and 1-hydroxycyclohexyl phenyl ketone; a component B: soft water, ammonium persulfate and oxidized water; a component C: soft water and tert-butyl hydroperoxide; a component D: soft water and rongalite; a component E: a defoaming agent; a component F: ammonium hydroxide with concentration being 20%. The glue can be applied to the sticky mat film and has high drying speed and lower drying temperature, and the produced film is good in transparency and not prone to tackifying or glue failure.
