CN105712629A - Transparent glaze slip for under-glaze painting - Google Patents

Abstract

The invention discloses transparent glaze slip for under-glaze painting and relates to the technical field of ceramic manufacturing. The transparent glaze slip is prepared from raw materials in parts by weight as follows: 25-30 parts of feldspar powder, 10-15 parts of zeolite powder, 10-15 parts of silica powder, 8-12 parts of molecular sieve raw powder, 6-10 parts of terpene resin, 5-8 parts of natural rubber, 5-8 parts of polyacrylamide, 4-6 parts of polyvinyl alcohol, 3-5 parts of calcium stearoyl lactylate, 2-3 parts of sodium alginate, 1-2 parts of nano-antimony trioxide and 100-150 parts of water. The glaze slip can form a smooth, transparent and bright glaze surface quickly after being sprayed on a ceramic biscuit and can greatly improve the presentation effect of patterns while the painted patterns are not affected, the glaze surface has excellent wear resistance, corrosion resistance, weather resistance and other performance, and accordingly, the market competitiveness of prepared ceramic is improved.

Description

A kind of underglaze colour paints transparent glaze slip

Technical field:

The present invention relates to ceramic fabrication technique field, be specifically related to a kind of underglaze colour and paint transparent glaze slip.

Background technology:

Underglaze colour paint be porcelain muffle painting decoration one, be pottery primary decoration means.Carrying out colored drawing on green compact or biscuiting glazed body, then execute layer of transparent glaze, last glaze firing is underglaze colour and paints.It is different from common glaze that underglaze colour paints glaze used, not only needs to be firmly attached on coloured drawing pigment, can't affect colored drawing pattern effect, it is necessary to adopts transparent glaze slip, is ensureing to improve further on the basis of quality the visual effect of pattern.

Summary of the invention:

The technical problem to be solved is in that to provide that a kind of adhesive force is strong, weatherability and the good underglaze colour of wearability paint transparent glaze slip.

The technical problem to be solved adopts following technical scheme to realize:

A kind of underglaze colour paints transparent glaze slip, is made up of the raw material of following parts by weight:

Feldspar powder 25-30 part, zeolite powder 10-15 part, silicon powder 10-15 part, molecular screen primary powder 8-12 part, terpene resin 6-10 part, natural rubber 5-8 part, polyacrylamide 5-8 part, polyvinyl alcohol 4-6 part, CSL 3-5 part, sodium alginate 2-3 part, nanmeter antimong trioxide 1-2 part, water 100-150 part.

Its preparation method comprises the steps:

(1) adding feldspar powder and zeolite powder in 1/2 water, stirring forms even slurry, adds terpene resin and nanmeter antimong trioxide, after being sufficiently mixed under microwave frequency 2450MHz, power 800W microwave treatment 10min, obtain material I；

(2) in residue water, add natural rubber and polyvinyl alcohol, be sufficiently mixed post-heating to reflux state isothermal holding 15min, be subsequently adding silicon powder and molecular screen primary powder, continue isothermal holding 10min, obtain material II；

(3) in material I, add material II, polyacrylamide, CSL and sodium alginate, be sufficiently mixed after uniformly and add in ball mill, be milled to fineness less than 15 μm.

The invention has the beneficial effects as follows: the transparent clarification of the made glaze slip of the present invention, adhesive force is strong, it is sprayed on biscuit of ceramics and can quickly form smooth bright glaze paint, without influence on colored drawing pattern, what be greatly improved pattern on the contrary presents effect, and this glaze paint has the performances such as the wearability of excellence, corrosion resistance and weatherability, thus strengthening the market competitiveness of made pottery.

Detailed description of the invention:

For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with specific embodiment, the present invention is expanded on further.

Embodiment 1

(1) in 60 parts of water, 25 parts of feldspar powders and 12 parts of zeolite powders are added, stirring forms even slurry, add 6 parts of terpene resins and 1 part of nanmeter antimong trioxide, after being sufficiently mixed under microwave frequency 2450MHz, power 800W microwave treatment 10min, obtain material I；

(2) in 60 parts of water, add 5 parts of natural rubbers and 6 parts of polyvinyl alcohol, be sufficiently mixed post-heating to reflux state isothermal holding 15min, be subsequently adding 12 parts of silicon powders and 8 parts of molecular screen primary powders, continue isothermal holding 10min, obtain material II；
