Description
Technical field
The present invention relates to the enamel field, be specifically related to a kind of cover-coat enamel slurry, white enamel and cover-coat enamel slurry and white enamelled preparation method.
Background technology
Enamel be the unorganic glass material is coagulated on matrix metal by fusion and with metal mortise a kind of matrix material together.The enamelled coating is generally by two-layer, and the one deck that contacts with metal base is the middle layer, i.e. ground-coat enamel, ground-coat enamel is the transition layer that mutually combines with metal base, have stronger adherence, cover-coat enamel is coated on the ground-coat enamel, rises to hide background color and give goods with the surface of smooth and beautiful appearance and good physical and chemical performance.There is good physical and chemical performance in traditional enamel product fields such as daily life, medicine, chemical industry, environmental protection that are applied to of many uses, have metal inherent physical strength and processing characteristics, and the smooth of glass arranged again, clean advantages such as attractive in appearance, corrosion-resistant, nontoxic.
But enamelled antibacterium and mould poor performance can be adsorbed various harmful bacteriums and mould, influence HUMAN HEALTH.The employed antiseptic-germicide of people is organic antibacterial agent and inorganic antiseptic now, wherein organic antibacterial agent is thermo-labile, be suitable for the situation that course of processing temperature is lower than 300 ℃, be not suitable for enamelware pyritous complete processing, and after inorganic antiseptic is melt into the porcelain piece according to conventional enamel frit makeing method and material commonly used, owing to redox or itself have reasons such as color, make porcelain facing color instability or anti-microbial effect poor.
Summary of the invention
The problem that the present invention solves is to provide a kind of cover-coat enamel slurry, has anti-microbial effect by its enamel that constitutes, and keeps the color and luster on enamel layer surface, and is white in color.The present invention also provides this enamel glaze slip and white enamelled preparation method.
