Description
Technical field
The application belongs to paint field, particularly relates to a kind of pottery acroleic acid polyurethane powder coating.
Background technology
The various goods that pottery is is the material that main raw material is mixing, shaping through pulverizing and calcining is obtained with natural clay and various natural mineral.People were called pottery the article of high-temperature firing in special kiln be made into potter's clay in the past, and pottery is the general name of pottery and porcelain.The traditional concept of pottery refers to all artificial Industrial products being raw material with Inorganic nonmetal mineral such as clays.It comprises by clay or containing the mixture of clay through mixing, be shaped, calcining and the various goods made.All belonged to its scope to the meticulousst fine pottery and porcelain by the most coarse earthenware.Main raw material for it takes from natural silicate minerals (as clay, quartz etc.), therefore with industry such as glass, cement, enamel, refractory materialss, belongs to the category of " silicate industry ".Ceramic industry is very fast in China's development, and selling market turns to rise gradually.China is a Production of Ceramics big country, also increasing to the demand of pottery.From domestic market situation, in recent years have a gratifying situation, supply falls short of demand for new, special products of famous brands, of extra fine quality ceramic product, high-grade ceramic and medium-to-high grade snitaryware very in great demand, the measured traditional product of matter continues to be in great demand, unsalable just ropy product.
Coating, is be applied to body surface can be formed and have protection, the class I liquid I of solid-state film of decoration or property (as insulation, anticorrosion, mark etc.) or the general name of solid material, comprises oil (property) paint, water-miscible paint, powder coating.Paint is flowable liquid coating, comprises oil (property) paint and water-miscible paint.Paint take organic solvent as medium or high solid, solvent-free oil-base paint.Water-miscible paint is used water dissolving or the coating with water-dispersion.Coating is as one of the main material of house decoration, and the large percentage accounted in decorations, buys the whether qualified environment directly having influence on overall finishing effect and room of coating, sometimes even can produce harm greatly to the health of human body.Founding of New, over 60 years, along with the development of national economy every profession and trade, progressively develops into the requisite important industry of all fields of national economy as its supporting coatings industry from an extremely unobtrusive little industry.Through the struggling hard of several generations, pioneer and keep forging ahead, China has become second-biggest-in-the-world coating material production state and country of consumption, enters into the main flow of world's coating industry development.
Ceramic coating weathering resistance and processing characteristics excellence, bear dirty and resistant to damage.Although ceramic coating resistant to damage in the past, if carry out bending machining to the parts after application, easily cracks, and fluorine resin paints and organic coating, easily by the damage such as sandstone, dust.Therefore, the appearance of ceramic coating, receives the favor of ceramic industry, and the infiltration of forward other industry, promise well.Ceramic coating is that one can make organism and inorganics react, thus has had both the novel ceramic coating of both advantages.The hardness of the ceramic coating of a new generation can reach more than 6H.High temperature resistant 400 degree, not sticky effect, color is multiple.And dimethylbenzene ceramic coating can be made.And universal along with humanity concept, and the formation of novel harmonious society, designs that a kind of glossiness is high, shock-resistance strong, strong adhesion and the pottery acroleic acid polyurethane powder coating of the good excellence of solvent resistance is very important.
