Abstract

The invention discloses a special enhancer capable of replacing clay ceramics. The enhancer is prepared from the following components in percentage by mass: 30-56 percent of a water-soluble high-molecular polymer adhesive, 20-35 percent of an inorganic adhesive, 8-15 percent of a deflocculating agent and 1-12 percent of a defoaming agent. The enhancer can be used for greatly improving the breaking strength of a green body, improving green body granule cracking, increasing the fluidity of a powder material and improving the binding performance of a powder body, has a remarkable effect on the defects of cracks and easily broken corners of the green body, and is capable of increasing the drying speed and firing speed of the green body in a kiln, so that the firing time can be shortened, and the capacity can be improved.

Description

The special toughener of a kind of alternative clay pottery

Technical field

The present invention relates to ceramic industry, specifically the special toughener of a kind of alternative clay pottery.

Background technology

Ceramics reinforcing agent is applied in porcelain production process, the kaolin poor to quality, often needs to add the intensity that ceramics reinforcing agent makes up its plasticity difference or improves early-products.Use ceramics reinforcing agent also can replace expensive vinyl acetate simultaneously.In Production of Ceramics process, add ceramics reinforcing agent, both can improve the intensity of just porcelain making goods, also can improve its oilness, as the lubricant in Production of Ceramics process, the shaping of base substrate can be promoted, prevent sticking to mould, make product be easy to the demoulding, improve final product quality and yield rate.

Although there are some ceramics reinforcing agents in the market, use and can affect mud property, powder mobility in various degree, produce pin hole, evil mind phenomenon, even have influence on the shaping of adobe.So be badly in need of a kind of product of research, under the prerequisite greatly strengthening base substrate folding strength, to mud property without any detrimentally affect, to solution base substrate crackle, corner rapid wear

There is positive effect etc. defect, the rate of drying of base substrate in kiln can also be improved, burn till speed.

Summary of the invention

The object of the present invention is to provide the special toughener of a kind of alternative clay pottery, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the invention provides following technical scheme:

The special toughener of a kind of alternative clay pottery, its component is calculated by mass percentage: high molecular weight water soluble polymer tackiness agent 30 ~ 56%, inorganic adhesive 20 ~ 35%, liquefactent 8 ~ 15%, defoamer 1 ~ 12%; Described high molecular weight water soluble polymer tackiness agent is at least one in polyvinylpyrrolidone (PVP), polyacrylamide (PAM), Xylo-Mucine (CMC), described inorganic adhesive is silicate salt-type binders, described liquefactent is sodium carbonate or flexibility water reducer (AST), and described defoamer is silicon polyethers or organosilicon.

Advantage of the present invention: this ceramic special toughener can increase substantially the folding strength of base substrate, improves base substrate grain and splits; Increase the mobility of powder, improve the bonding properties of powder; Positive effect is had to defects such as solution base substrate crackle, corner rapid wears; The rate of drying of base substrate in kiln can also be improved, burn till speed, thus shorten firing time, improve production capacity.

Embodiment

Below the technical scheme in the embodiment of the present invention is clearly and completely described.

The special toughener of a kind of alternative clay pottery, composed as follows:

Polyvinylpyrrolidone (PVP) 50%

Silicate salt-type binders 32%

Flexibility water reducer (AST) 10%

Silicon polyethers 8%

Above-mentioned raw materials proportioning adds in the ceramic mud prepared in porcelain blank and in kiln calcining, after tested, the folding strength of base substrate can increase about 65%, and the rate of drying of base substrate in kiln, the speed of burning till improve more than 40%.

Above embodiment is only introduces preferred case of the present invention, to those skilled in the art, not deviating from any apparent changes and improvements of carrying out in the scope of spirit of the present invention, all should be regarded as a part of the present invention.

Claims

1. the special toughener of alternative clay pottery, it is characterized in that, its component is calculated by mass percentage: high molecular weight water soluble polymer tackiness agent 30 ~ 56%, inorganic adhesive 20 ~ 35%, liquefactent 8 ~ 15%, defoamer 1 ~ 12%; Described high molecular weight water soluble polymer tackiness agent is at least one in polyvinylpyrrolidone (PVP), polyacrylamide (PAM), Xylo-Mucine (CMC), described inorganic adhesive is silicate salt-type binders, described liquefactent is sodium carbonate or flexibility water reducer (AST), and described defoamer is silicon polyethers or organosilicon.
