The invention relates to an automobile PU foaming mold cavity surface
ceramic plating process. The automobile PU foaming mold cavity surface
ceramic plating process includes the following steps that 1), the surface of an automobile PU foaming mold cavity is cleaned and degreased, a mold is heated to 385 DEG C, and then heat preservation is carried out for 30 min; 2),
sand blasting is carried out, specifically 70-100-mesh
quartz sand is sprayed; 3), after the mold is cooled to 40-60 DEG C, spraying of
ceramic plating
coating is started, a
coating tool is used for uniform spraying, the ceramic plating
coating is sprayed to the mold once, and the thickness of a coating formed after spraying is 30-50 micrometers; and 4), after the mold is heated to 120 DEG C after spraying is completed, heat preservation is carried out for 10 min, after the mold continues to be heated to 180 DEG C, heat preservation is carried out for 10 min, finally, after the mold is heated to 220-240 DEG C, enamelation is carried out for 30 min, and after the mold is naturally cooled, ceramic plating is completed. The automobile PU foaming mold cavity surface ceramic plating process has the beneficial effects that the
ceramic coating can
resist the high temperature of 600 DEG C, and therefore the similar problems can be effectively avoided through the
ceramic coating.
