Embodiment 1
[0097] In the first mixer 1-1, feed 12.85 parts (parts by weight, the same below) methyl methacrylate, 11.4 parts butyl acrylate, 18.6 parts butyl methacrylate, 6.1 parts hydroxyethyl acrylate, 0.06 parts Acrylic acid, 10 parts of xylene and 10 parts of butyl acetate were uniformly mixed to obtain the first mixed liquid. Pass 1 part of tert-butyl peroxyacetate and 30 parts of butyl acetate into the second mixer 1-2, and mix evenly to obtain the second mixed solution.
[0098] The first mixed liquid is sent to the first material heat exchange system 6-1 to be preheated to 110°C through the material delivery system 2, and the second mixed liquid is sent to the second material system 6-2 to be preheated to 100°C through the material delivery system 2. The preheated first mixed liquid and the second mixed liquid are continuously transported by the feed pump into the continuous channel reactor in which the microchannel reactor and the static tubular reactor are sequentially connect...
Embodiment 2
[0102] Into the first mixer 1-1, 18.43 parts of styrene, 14.58 parts of methyl acrylate, 5.23 parts of ethyl acrylate, 6.05 parts of isooctyl methacrylate, 4.6 parts of hydroxyethyl methacrylate, 4 parts of acrylic acid Hydroxypropyl ester, 0.14 parts of acrylic acid, 10 parts of xylene and 5 parts of butyl acetate were uniformly mixed to obtain the first mixed solution. 2 parts of tert-butyl peroxide cumene, 10 parts of xylene and 20 parts of butyl acetate were passed into the second mixer 1-2, and mixed uniformly to obtain a second mixed liquid.
[0103]The first mixed liquid is sent to the first material heat exchange system 6-1 to be preheated to 163°C through the material delivery system 2, and the second mixed liquid is sent to the second material system 6-2 to be preheated to 92°C through the material delivery system 2. The preheated first mixed liquid and the second mixed liquid are continuously transported by the feed pump into the continuous channel reactor in series...
Embodiment 3
[0107] Into the first mixer 1-1, 12.3 parts of styrene, 9.66 parts of methyl methacrylate, 10.56 parts of butyl acrylate, 14.04 parts of isooctyl methacrylate, 4.7 parts of hydroxypropyl acrylate, 6 parts of methyl Hydroxyethyl acrylate, 0.3 parts of acrylic acid and 15 parts of xylene were mixed uniformly to obtain the first mixed liquid. Pass 2.5 parts of diisopropyl peroxide and 25 parts of butyl acetate into the second mixer 1-2, and mix uniformly to obtain the second mixed solution.
[0108] The first mixed liquid is sent to the first material heat exchange system 6-1 to be preheated to 179°C through the material delivery system 2, and the second mixed liquid is sent to the second material system 6-2 to be preheated to 74°C through the material delivery system 2. The preheated first mixed liquid and the second mixed liquid are continuously transported by the feed pump into the continuous channel reactor in which the static mixer and the static tubular reactor are sequenti...
