The invention discloses a preparation method of a multi-layer wear-resistant heat-resistant
lacquer vessel, and relates to the technical field of natural paint
processing.The preparation method comprises the steps that natural
lacquer is filtered and dewatered, and a
lacquer base material is obtained; blending the lacquer base material in batches, adding a
vegetable oil flexibilizer and nano
cellulose into one part of the lacquer base material, uniformly dispersing the
vegetable oil flexibilizer and the nano
cellulose to form bottom-layer lacquer ash, adding
chitosan nano
crystal and
ceramic powder into the other part of the lacquer base material, mixing the
chitosan nano
crystal and the
ceramic powder to form middle-layer lacquer ash, adding high-concentration nano
cellulose and a
surface cleaning aid into the rest part of the lacquer base material,
grinding and homogenizing to form surface-layer lacquer ash; carrying out
surface cleaning and micro-
polishing treatment on the vessel
green body to obtain an active substrate; the active substrate is coated with bottom layer paint ash and leveled, and a bottom layer
coating is formed; the vessel coated with the bottom
coating is placed in an intelligent temperature and
humidity linkage curing platform, the environment temperature and
humidity are regulated and controlled by monitoring the state of a paint film, and curing of the bottom
coating is achieved; and sequentially coating and curing the middle layer paint ash twice on the cured bottom layer coating to construct a double-layer middle structure.
