Embodiment 1

[0045]1) Formula: 40 parts of coal gangue, 20 parts of feldspar, 20 parts of calcined high-alumina bauxite, 8 parts of jiexiu soil, 10 parts of Zimujie soil, 2.5 parts of Suzhou soil, 5 parts of Fangzi soil, and 1 part of cooked talc .

[0046] 2) Preparation process:

[0047] a. Crush the coal gangue to 8-40 meshes, mix it with other raw materials according to the formula, add water ball mill for 18-20 hours, the amount of water added is generally 50% of the total weight of raw materials, add soda ash and water glass to adjust the pH of the mud to 8-10 ;

[0048] b. Pass through a 150-200 mesh sieve after ball milling, put the mud into a high-level vacuum tank after removing iron, add water to adjust the specific gravity of the mud to 1.50-1.65, and vacuumize for 10-25 minutes at a vacuum degree of 0.08MPa-0.09MPa;

[0049] c. Remove iron, inject grout, hold the grout for 30-40 minutes and then empty the grout;

[0050] d. Adhesive bottom support, mold release, billet trim...

Embodiment 2

[0055] 1) Formula: 10 parts of coal gangue, 10 parts of feldspar, 10 parts of calcined high-alumina bauxite, 5 parts of jiexiu soil, 5 parts of Zimujie soil, 1 part of Suzhou soil, 8 parts of Fangzi soil, 3 parts of cooked talc .

[0056] The preparation method is basically the same as that in Example 1, except that after the drying process, the hemping process is carried out first, and then the glazing process is carried out. The hemping process specifically includes the following steps: use a spray gun to spray a particle size of 0.5 to 0.8mm quartz sand, glass balls, alumina balls or zirconia balls.

Embodiment 3

[0058] 1) Formula: 50 parts of coal gangue, 22 parts of feldspar, 30 parts of calcined high-alumina bauxite, 10 parts of calcined soil, 15 parts of Zimujie soil, 3 parts of Suzhou soil, 6 parts of Fangzi soil, 2 parts of cooked talc . The preparation method is basically the same as in Example 1.

Abstract

This invention relates to a method for making hand mould used for production of gloves by impregnation. The raw materials (based weight parts) are: gangue 10-50 parts, feldspar 10-22 parts, sintered bauxite 10-30 parts, Jiexiu earth 5-10 parts, violet mujie earth 5-15 parts, Suzhou earth 1-3 parts. This invention method utilizes vacuum foam-removing method, eliminating the water-removing of mud, cake-preparation and glue-removing, so this invention has advantages of: simple process, low cost, fuel-saving and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of impregnated ceramic hand molds for producing plastic gloves, and in particular relates to a method for making ceramic hand molds. Background technique [0002] The hand mold is a hand mold used to produce plastic gloves by dipping method. The production process of various liquid-formed plastic gloves is: [0003] It is made by dipping the plastic liquid material on the ceramic hand mold, washing with alkali, pickling, drying and demoulding. The hand molds used in production should be acid-resistant, alkali-resistant, chemical-resistant, and have a certain thermal shock resistance. [0004] Publication number is that the Chinese patent of CN1765816A discloses a kind of method for making the ceramic hand mold that is applicable to the production of nitrile rubber glove, comprises raw material formula, mud fineness, firing temperature, is characterized in that: a) raw material formula: by following weight ...
