The invention relates to the field of ceramic manufacturing, in particular to high-temperature under-glaze colored porcelain and a firing process thereof.The high-temperature under-glaze colored porcelain comprises a green body, the green body is sequentially covered with a transparent glaze layer, a texture layer and a flock texture layer from top to bottom, the raw material of the transparent glaze layer is transparent glaze, the raw material of the texture layer is a color toner and a crystallization toner, and the raw material of the flock texture layer is flock texture glaze. Cracks similar to pigeon velvet are formed after the velvet grain layer is sintered, the transparent glaze is high in brightness and good in fluidity, the fineness of velvet grain glaze slip is smaller than that of the transparent glaze, and meanwhile the high-temperature viscosity is larger than that of the transparent glaze, so that during high-temperature sintering, after the velvet grain layer generates the cracks, the glaze surface flows to fill the cracks, and the unique decoration style of the cracks under the glaze is formed; and under-glaze color lines and crystal lines are formed between the color colorant and the crystal colorant, so that the glaze has unique aesthetic feeling.

This invention belongs to the field of asphalt modification technology and discloses a high-performance rubber composite modified asphalt and its preparation method. The high-performance rubber composite modified asphalt is prepared by mixing asphalt and a high-performance rubber composite granular modifier. The high-performance rubber composite granular modifier is obtained by extruding and granulating a novel thermoplastic elastomer, desulfurized rubber powder, and a rubber deodorizer using a multi-stage screw extruder. The novel thermoplastic elastomer is obtained by chemical grafting of a moderately pyrolyzed rubber polymer, a thermoplastic elastomer, and a second free radical scavenger. The desulfurized rubber powder is obtained by high-temperature oxygen-free degradation of a second rubber powder and a third free radical scavenger. Compared with traditional rubber composite modified asphalt, the modified asphalt of this invention exhibits superior high and low temperature performance, heat and oxygen aging resistance, and storage stability. It also has good workability, minimal performance degradation during long-term high-temperature storage, significantly reduced odor emissions, and a more stable and lasting odor-neutralizing effect.
