Problems solved by technology

[0002] In the process of developing lead-free glaze, due to the removal of PbO (lead oxide) as a strong additive in the glaze, the problem of high-temperature viscosity increase of the glaze and poor gloss of the glaze; the introduction of K 2 O, Na 2 O, CaO and other elements glaze expansion coefficient is too large to cause cracking problems; and the current use of British muffle glaze firing kilns has problems such as excessive temperature difference

Embodiment Construction

[0019] This green enamel can be made of marble from Meixian, Guangdong, quartz from Sangpu Mountain, Guangdong, potassium feldspar from Dongwei, Jieyang, Guangdong, talc from Xinyi, Guangxi, etc. The mud washing is provided by Chaozhou Qiajia Porcelain Co., Ltd. Praseodymium yellow provided by Chaozhou Fengxi District Xingquanye Ceramic Raw Material Factory and vanadium-zirconium blue provided by Chaozhou Xuri Chemical Materials Co., Ltd. were used. Its production process is:

[0020] A) marble, potassium feldspar are pulverized, cross 80 mesh sieves, for subsequent use;

[0021] B) calcining the quartz and talc at 1320° C. for 4-5 hours, taking out and cooling, pulverizing, passing through an 80-mesh sieve, and setting aside;

[0022] C) batching: mix marble powder 20kg, potassium feldspar powder 50kg, quartz powder 13kg, talcum powder 9kg and washing mud 8kg, ball mill in a ball mill for 10-20 hours, and pass through a 320 mesh sieve;

[0023] D) magnetic separation iron r...

Abstract

The invention belongs to the technical field of ceramic glazes, in particular to environmental-protection green enamel and a production method thereof. The environmental-protection green enamel comprises the following components in percentage by weight: 15-25 marble, 48-55 K-feldspar, 10-18 quartz, 5-11 talc, 6-12 mud, 2-5 praseodymium yellow, and 1-3 vanadium-zirconium blue. The production method of the environmental-protection green enamel comprises the steps of: preparing materials, calcining, sieving, ball-milling, removing iron by magnetic separation, adding chromophore and stirring, sintering the materials in a shuttle kiln, keeping the temperature of 1120 DEG C for one hour, keeping raising temperature to 1230 DEG C and keeping the temperature for 20 minutes, and then water milling and aging. The invention has the advantages of environmental protection, no lead, cadmium, alkali or other harmful elements, low production cost, easily obtained material resources, simple process, short sintering time and low energy consumption; in addition, a product using the green enamel has gentle surface gloss, good flatness and no pinholes.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes, in particular to an environment-friendly green enamel and a production method thereof. Background technique [0002] In the process of developing lead-free glaze, due to the removal of PbO (lead oxide) as a strong additive in the glaze, the problem of high-temperature viscosity increase of the glaze and poor gloss of the glaze; the introduction of K 2 O, Na 2 O, CaO and other elements glaze expansion coefficient is too large to cause cracking problems; and the current use of British muffle glaze firing kiln is too large temperature difference and other problems. Contents of the invention [0003] The purpose of the present invention is to provide a new generation of lead-free "environmental protection green enamel", so that its various indicators meet the requirements of lead-free, non-toxic and suitable for modern large-scale production. [0004] In the present invention, the environm...
