Abstract
The present invention discloses a kind of low-cost high-strength white clouds greenwave body, it is fired in multiple elements design dicyandiamide solution by base-material and additive, base-material includes eluriating 25~35wt% of mud, 10~15wt% of smolmitza, 0~1wt% of bentonite, 5~6wt% of pyrophillite, 12~25wt% of hypothermia grait, 3~8wt% of lithium porcelain stone, 5~12wt% of dolomite, 6~12wt% of black talc, 6~10wt% of lime stone, 8~15wt% of diopside, Yongchun 0~5wt% of thick soil, useless 0~5wt% of porcelain powder；Additive is organic silicon nano liquid, and the weight percent of opposite base-material is 1~3%.The present invention is by being added multielement composite fluxing agent, firing temperature is greatly reduced in the especially addition of elemental lithium and organic silicon nano liquid, and since organic silicon nano liquid forms mullite crystal at low temperature, elemental lithium easily forms the high glass phase of intensity in easy fired, improves blank strength and degradable.
Description
Technical field
The present invention relates to ceramic technical fields, more particularly to a kind of low-cost high-strength white clouds greenwave body and its system
Preparation Method.
Background technique
White clouds pottery is also known as light ceramics, is the environment-friendly ceramic product generally acknowledged on international market.Lightweight white clouds pottery can be applied
Coloured glaze colored drawing, can be made various types, such as tea tableware, craftwork, and appearance looks elegant is popular among consumers.It is especially white
Yun Tao is since water absorption rate is big, after broken tile is embedded under soil, makes moist degradable, is finally divided into soil, and other hard-pastes
Without this function, so white clouds pottery takes from the soil of underground, finally becomes soil again after completing mission, be to belong to enviroment protective ceramic
Product.
But many producers develop and strengthen white clouds mud, in order to improve the mechanical strength of white clouds pottery, improve firing temperature (1080
DEG C -1130 DEG C), reach half porcelain, reduce the degradation function of white clouds pottery, and does not meet the purpose of white clouds pottery energy-saving and emission-reduction.
The compression of increase glaze is proposed to improve intensity there are also research patent, and firing temperature also reaches 1080 ± 15 DEG C, generally
Glaze is all in compressive stress state, and the method by improving compression raising intensity is unreliable, is difficult to control, controls bad meeting
Reduce the intensity of white clouds pottery.
Utility model content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of raw materials to be easy to get, it is cheap, can guarantee produce
The white clouds greenwave body of product performance indicator, and meet white clouds and make pottery degradable function, meet the policy of national energy conservation and emission reduction.
The technical solution that the present invention uses is: a kind of low-cost high-strength white clouds greenwave body, the green body by base-material with
Additive is fired in multiple elements design flux system, wherein the additive is organic silicon nano liquid, and green body obtained is inhaled
