Abstract

The invention relates to ceramics of improving mechanical strength and cold and hot shock property and a preparation method thereof. The ceramics comprises the following components: bauxite, clay and feldspar, and has lower cost and better mechanical, electrical and thermal properties, thereby being widely applied to industries of electrical ceramics manufacture, and the like; however, some products need higher mechanical strength and expansion resistance and better cold and hot shock property, the ceramics can not meet the requirements of the product. The preparation method comprises the following steps: firstly, weighting 35-50 percent of bauxite, 40-50 percent of clay, 9-20 percent of feldspar, 1.5-4 percent of zinc oxide, and 0.1 percent of sodium humate according to the mass percentage; secondly, performing the ball-milling according to the proportion of composite to zirconia balls to water being 1:1.5:1 until the weight of screen residue of a multiple-hole sieve is less than 0.2 percent; thirdly, performing the lime sludge, pugging and mustiness for more than 48h to the raw materials, forming, drying and glazing; and fourthly, sintering at 1200-1250 DEG C. The invention improves the sintering property because the zinc oxide and silicon oxide form eutectic under high temperature, promotes porzite to generate, achieves the purpose of improving the mechanical strength of the ceramics, and can improve the cold and hot shock property of the ceramics.

Description

A kind of physical strength and cold and hot shock property pottery and preparation method thereof of improving
Technical field
The invention belongs to field of inorganic nonmetallic material, be specifically related to a kind of physical strength and cold and hot shock property pottery and preparation method thereof of improving.
Technical background
Stupalith principal constituent: bauxitic clay, clay, feldspar.This material cost is lower, machine, and electricity, thermal characteristics is better, is widely used in industries such as electroceramics manufacturing, but the higher physical strength of some product needed, anti-ability and the better cold and hot shock property of expanding, this material can not satisfy product demand.
Summary of the invention
Technical problem to be solved by this invention provides pottery of a kind of cold and hot shock property that improves porcelain physical strength and porcelain and preparation method thereof.
For solving above-mentioned technical problem, the technical scheme that the present invention takes:
A kind of physical strength and cold and hot shock property pottery of improving, its special character is: it is as follows that described ceramic raw material constituent is pressed the mass percent proportioning:
Bauxitic clay 35%-50% clay 40%-50% feldspar 9%-20% zinc oxide 1.5%-4%
Sodium salts humic acids 0.1%
The preparation method's of above-mentioned improved physical strength and cold and hot shock property pottery special character is: described preparation method is undertaken by following step: take by weighing constituent according to the above ratio, at first by constituent: zirconia ball: water=1: 1.5: 1 carries out ball milling, ball milling to the 10000-hole sieve screen over-size less than 0.2%, again raw material is carried out filter mud, pugging, old more than 48 hours, moulding, drying, glazing, fire at 1200 ℃-1250 ℃ at last.
Compared with prior art, zinc oxide of the present invention and silicon oxide at high temperature form eutectic, improve sintering character, impel mullite to generate, reach the purpose that improves the porcelain physical strength, because zinc oxide material has the attribute that absorbs macro-energy, so can improve the cold and hot shock property of porcelain.
Description of drawings
Fig. 1 is the process flow sheet of invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Constituent of the present invention comprises bauxitic clay, clay, feldspar, zinc oxide, Sodium salts humic acids, and it is as follows that constituent is pressed the mass percent proportioning:
Bauxitic clay 35%-50% clay 40%-50% feldspar 9%-20% zinc oxide 1.5%-4%
Sodium salts humic acids 0.1%
Embodiment one:
Take by weighing constituent by mass percent:
Bauxitic clay 35% clay 40% feldspar 9% zinc oxide 1.5% Sodium salts humic acids 0.1%
At first by constituent: zirconia ball: water=1: 1.5: 1 carries out ball milling, ball milling to the 10000-hole sieve surplus less than 0.2%, again raw material is carried out filter mud, pugging, old more than 48 hours, moulding, drying, glazing, fire at 1200 ℃ at last.
Embodiment two:
Take by weighing constituent by mass percent:

At first by constituent: zirconia ball: water=1: 1.5: 1 carries out ball milling, ball milling to the 10000-hole sieve surplus less than 0.2%, again raw material is carried out filter mud, pugging, old more than 48 hours, moulding, drying, glazing, fire at 1250 ℃ at last.
Embodiment three:
Take by weighing constituent by mass percent:
Bauxitic clay 42.5% clay 45% feldspar 14.5% zinc oxide 2.75% Sodium salts humic acids 0.1%
At first by constituent: zirconia ball: water=1: 1.5: 1 carries out ball milling, ball milling to the 10000-hole sieve surplus less than 0.2%, again raw material is carried out filter mud, pugging, old more than 48 hours, moulding, drying, glazing, fire at 1225 ℃ at last.
Zinc oxide and silicon oxide at high temperature form eutectic, improve sintering character, impel mullite to generate, and reach the purpose that improves the porcelain physical strength, because zinc oxide material has the attribute that absorbs macro-energy, so can improve the cold and hot shock property of porcelain.
The anti-test of expanding of hydraulic pressure in carrying out: the average hydraulic pressure demolition point of existing pottery is 12MP, and the average hydraulic pressure demolition point of gained pottery of the present invention is 16MP.
Testing data contrasts as following table:
Project name Unit Current material Material of the present invention
Bending strength is not less than Mpa 150 200
Cold and hot acute degeneration is not less than K 150 300
Interior hydraulic pressure detects Mpa 12 16
