Embodiment 1

[0047] The present invention utilizes sodium chloride raw material to produce the method for ceramic imitation material, and the detailed steps of this production method are as follows:

[0048] a. Using sodium chloride as the basic raw material (the mass percentage of sodium chloride used is ≥ 91%, and the particle size is 0.1-1.5 mm), adding sintering aid low melting point glass powder and colorant cobalt oxide; The mass ratio that adds between sodium chloride and low-melting point glass powder is 20:1, and the addition of described cobaltous oxide accounts for 0.2% of the total mass of sodium chloride;

[0049] B, the mixing of sodium chloride and sintering aid, coloring agent: prepare raw material sodium chloride, low-melting point glass powder and cobaltous oxide respectively according to the proportioning ratio of various raw materials described in step a, prepare sodium chloride Put it in an open container, add the prepared low melting point glass powder and cobaltous o...

Embodiment 2

[0055] Embodiment 2: basically the same as Embodiment 1, the difference is:

[0056] In step a: add sintering aid sodium hexametaphosphate and colorant ferric oxide; the mass ratio between the sodium chloride and sodium hexametaphosphate is 20:2, the ferric oxide The amount added accounts for 0.5% of the total mass of sodium chloride;

[0057] In step c: the adhesive is a polyvinyl alcohol resin PVA aqueous solution (the mass percent concentration of the PVA aqueous solution is 5%), and the amount added accounts for 6% of the total weight of the three raw materials of sodium chloride, sintering aid and colorant ;

[0058] In step d: when the molding pressure reaches 10t, keep the pressure for 30s;

[0059] In step e: when the pressure reaches 100MPa, keep the pressure for 5 minutes;

[0060] In step f: Then, the temperature is raised from 300° C. to a firing temperature of 500° C. at a heating rate of 1.5° C. / min, and the firing time is 180 minutes.

Embodiment 3

[0061] Embodiment 3: basically the same as Embodiment 1, the difference is:

[0062] In step a: adding sintering aid aluminum oxide and colorant copper oxide; the mass ratio between the sodium chloride and aluminum oxide is 18:1, and the added amount of copper oxide accounts for the total mass of sodium chloride 1.0% of;

[0063] In step c: the binder is an aqueous solution of sodium carboxymethyl cellulose (the mass percent concentration of the aqueous solution is 4%), and the amount added accounts for 4% of the total weight of the three raw materials of sodium chloride, sintering aid and colorant ;

[0064] In step d: when the molding pressure reaches 30t, keep the pressure for 8s;

[0065] In step e: when the pressure reaches 300MPa, keep the pressure for 1min;

[0066] In step f: Then, the temperature is raised from 300° C. to a firing temperature of 720° C. at a heating rate of 1.5° C. / min, and the firing time is 30 minutes.

Abstract

The invention discloses a method for using sodium chloride to produce simulated ceramic materials. The method includes: using sodium chloride, sintering additives and colorants as main raw materials, well mixing the raw materials, grinding into powder, placing the mixed powder into a grinding tank, adding adhesives for granulation and sieving, pre-pressing forming the mixed materials after sieving, performing vacuum sealing to the formed pre-pressed blocks, performing isostatic compaction after sealing, sintering the obtained compacted pressed blocks in a high-temperature furnace, and cooling after sintering to obtain the simulated ceramic materials. The method uses sodium chloride as main raw material to prepare the simulated ceramic materials by adding auxiliaries such as sintering additives and colorants and after processing such isostatic compaction and high-temperature sintering. The prepared simulated ceramic materials are similar to ceramics in appearance, have certain strength and is possible to be used in fields such as decorating materials, and products of different colors and patterns can be achieved by adding different colorants.

Description

technical field [0001] The invention relates to a production method of imitation ceramic material, in particular to a method for producing imitation ceramic material by utilizing sodium chloride raw material. Background technique [0002] In daily life, it is customary to refer to sodium chloride as "salt" for short. In addition to being used for food (commonly known as table salt), sodium chloride is widely used as a chemical raw material (commonly known as industrial salt). The chronology of the National Bureau of Statistics uses "raw salt" as a general term. Salt mine is a general term for NaCl, and its representative mineral is rock salt. The raw material sources of salt can be divided into four categories: sea salt, lake salt, well salt and mine salt. The salt made from seawater is called "sea salt"; the salt processed by mining modern salt lake mines is called "lake salt"; It is called "well salt"; the salt processed by mining ancient rock salt deposits is called "m...
