For film forming matter main inside coating：Acrylic resin needs the requirement for reaching high-solid lower-viscosity.However acrylic acid traditional at present
The production technology of resin is produced for non-pressure process, it is difficult to produce high-solid lower-viscosity, acrylic resin of fine qualities.Existing normal pressure
Method technique is as follows：25% solvent xylene, propylene glycol monomethyl ether etc. are put into reaction kettle bottom, are warming up to reflux temperature 135 ± 2
DEG C, then 75% mix monomer is slowly added dropwise：Methyl methacrylate (first methyl esters), butyl acrylate, styrene etc. and initiator：
Cumyl peroxide etc. keeps the temperature 4 hours, until reaction terminates.The shortcoming of the technique has：Temperature restriction is produced in solvent
Boiling point, the boiling point of Conventional solvents is relatively low, and range is at 80~136 DEG C.However the decomposition temperature of initiator is higher, range is 140
~160 DEG C.So causing when producing high-solid lower-viscosity acrylic resin, decomposition of initiator speed is slow, and molecular resin amount is big, viscosity
Height, molecular weight distribution are uneven.And in order to improve the distribution situation of molecular weight, if excessive uses molecular weight regulator for example
Lauryl mercaptan etc., then the weatherability and chemical resistance that can lead to resin again decline, so as to influence the performance of coating.
