The invention relates to an interior decoration
coating for an automobile lamp. The
coating comprises the following components by weight: 25 to 35% of novolac
epoxy resin, 20 to 30% of
acrylic resin, 5 to 10% of
polyester resin, 3 to 5% of TM resin, 2 to 7% of TP resin, 2 to 3% of an initiator, 3 to 4% of an auxiliary agent and 30 to 40% of a
solvent, wherein the
solvent is prepared from mixing propyl butyl ester and
ethyl ester with a weight proportion of 10 to 20% of propyl butyl ester and 80 to 90% of
ethyl ester; the initiator is one or two selected from the group consisting of
benzophenone and alpha-hydroxy
ketone; and the auxiliary agent is one or more selected from the group consisting of a
drying promoter, a
toughening agent, a defoaming agent, a leveling agent, a light stabilizer, etc.. The interior decoration
coating for the automobile lamp is effectively regulated in an internal
chemical structure and a molecular structure of the coating; and the molecular content of the coating is in a range of 15000 to 30000, so depainting, dark-moire and yellowing phenomenons of a modified
resin coating in the prior art are changed.
