Embodiment Construction
[0017] The present invention is described in detail below in conjunction with embodiment.
[0018] The special latex for dry-process dust-free paper of the present invention is a kind of styrene and acrylic acid ester copolymer, which belongs to the water-based polymer emulsion type adhesive, and the production process is as follows:
[0019] 1. Formula (according to 100 parts by mass):
[0020] Butyl acrylate 19, methyl acrylate 3, hydroxyethyl acrylate 4, styrene 12, acrylic acid 2, butyl methacrylate 1, NaHCO 3 , deionized water 55, initiator 0.4, emulsifier 3, stabilizer 0.6.
[0021] The above-mentioned initiator adopts ammonium persulfate, and the emulsifier adopts MS-1 and OP-10.
[0022] 2. Method:
[0023] Take butyl acrylate, methyl acrylate, hydroxyethyl acrylate, styrene, acrylic acid and butyl methacrylate according to the ratio of the formula, mix them thoroughly to form monomers, and put them into the monomer high tank of the polymerization kettle for standby...
