Antifouling glaze
The invention provides an antifouling glaze material. The glaze material is prepared from the following raw materials: polymethylsilane, nano zinc oxide, sodium hexametaphosphate, wollastonite, pyrophyllite, barium oxide and a stabilizer. Nano-zinc oxide in the raw materials of the antifouling glaze can improve the glossiness, whiteness and glaze microhardness of the glaze surface of a ceramic finished product, and can reduce the initial melting temperature of the glaze; sodium hexametaphosphate is a polyphosphoric acid weak acid sodium salt with a cyclic molecular structure. A nano zinc oxidedispersion system is stabilized by an electrostatic stabilization mechanism; sodium hexametaphosphate forms a molecular layer protective film on the surface of zinc oxide; the surface energy of zincoxide particles is reduced; the coating effect is achieved to a certain degree; therefore, agglomeration among particles can be effectively prevented; the nano zinc oxide is stably and uniformly dispersed in the glaze; the polymethylsilane has very good oxidation resistance; pyrophyllite forms a compact mineral protection layer on the surface of the glaze; by adding wollastonite, the wear resistance of the product can be improved, the surface roughness is reduced, the accumulation space of pollutants is lost, the pollution resistance of the ceramic product is effectively improved, and the wollastonite can enable the hardness of a fired glaze layer to be higher and the glaze layer to be more wear-resistant, so that the glaze disclosed by the invention not only has a very good antifouling function, but also has good wear resistance.
本发明提供了一种防污釉料，所述釉料的原料包括：聚甲基硅烷、纳米氧化锌、六偏磷酸钠、硅灰石、叶腊石、氧化钡和稳定剂。所述防污釉料原料中的纳米氧化锌可提高陶瓷成品釉面的光泽度、白度和釉面显微硬度，能降低釉的始熔温度；六偏磷酸钠是分子结构为环状的聚磷酸弱酸钠盐，以静电稳定机制使纳米氧化锌分散体系稳定，六偏磷酸钠在氧化锌的表面形成了分子层保护膜，降低了氧化锌粒子的表面能，在一定程度上起到包覆作用，从而使其能有效地防止粒子间的团聚，使纳米氧化锌稳定、均匀分散于釉料中，聚甲基硅烷具有很好的抗氧化性，叶腊石在釉料表面形成一层致密的矿物质保护层，能够增加产品的耐磨性能，降低了表面粗糙度，使污染物失去积聚空间，有效地提高了陶瓷制品的抗污性，硅灰石能够使烧成后釉层的硬度更大，更耐磨，因此本发明所述的釉料不仅具有很好的防污功能，而且耐磨性好。
