Embodiment 1

[0014] Example 1 The talc-porcelain composite grinding aid consists of the following raw materials in parts by mass:

[0015] Vinyl bis stearamide 15 parts

[0016] Polyethylene glycol fatty acid ester 15 parts

[0017] Sodium metasilicate 38 parts

[0018] Sodium hexametaphosphate 22 parts

[0019] After the above-mentioned raw materials are accurately weighed, they are fully stirred in a mixer to obtain a powdery mixture with no agglomerated particles and uniform color, which is packed into a sealed packaging bag to obtain the finished product of the talc-porcelain composite grinding aid.

[0020] When in use, take out the talc-porcelain composite grinding aid from the sealed packaging bag, add 3.5 kilograms of additives per ton of dry base ceramic raw materials, and add it into the ball mill after accurate weighing.

[0021] Compared with the blank sample without any additives, after adding 0.35% talc porcelain composite grinding aid, the ball milling time was shorten...

Embodiment 2

[0022] Example 2 The talc-porcelain composite grinding aid consists of the following raw materials in parts by mass:

[0023] Triethylhexyl phosphate 13

[0024] Polyethylene glycol 16

[0025] Sodium tripolyphosphate 30

[0026] Sodium metasilicate 25

[0027] Triethanolamine 16

[0028] First add 400 parts of deionized water to the container, then add accurately weighed triethylhexyl phosphate, polyethylene glycol, sodium tripolyphosphate, sodium metasilicate in sequence, and stir in a water bath at 80°C for 3 hours , then add triethanolamine, continue to stir for 0.5 hours, and finally pass the obtained liquid through a 250-mesh vibrating sieve to remove solid impurities therein, and obtain a finished product of talc-porcelain composite grinding aid with a solid content of 20%.

[0029] When in use, add 4.5 kilograms of additives per ton of dry base ceramic raw material, accurately weigh and add to the ball mill.

[0030] Compared with the blank sample without any ...

Embodiment 3

[0031] Example 3 : The talc porcelain composite grinding aid is made up of the following raw materials in parts by mass:

[0032] Polyethyleneimine 22

[0033] Polyethylene glycol 18

[0034] Sodium dodecylbenzenesulfonate 15

[0035] Sodium hexametaphosphate 30

[0036] Triisopropanolamine 15

[0037] First add 500 parts of deionized water to the container, then add accurately weighed polyethyleneimine, polyethylene glycol, sodium dodecylbenzenesulfonate, and sodium hexametaphosphate in sequence, and stir in a water bath at 60°C for 4 After one hour, add triisopropanolamine, continue to stir for 1 hour, and finally pass the obtained liquid through a 250-mesh vibrating sieve to remove solid impurities therein, and obtain a finished product of talc porcelain composite grinding aid with a solid content of 16.7%.

[0038] When in use, add 5 kg of additives per ton of dry base ceramic raw material, accurately weigh and add to the ball mill.

[0039] Compared with the blank ...

Abstract

The invention relates to a steatite ceramic compound grinding aid which is compounded by two or more raw materials in parts by weight: 5-20 parts of vinyl bistearamide, 3-15 parts of triethyl hexyl phosphate, 5-20 parts of polyethylene glycol aliphatic ester, 10-30 parts of polyethylene glycol, 15-25 parts of polyethyleneimine, 20-40 parts of sodium metasilicate, 20-40 parts of sodium tripolyphosphate, 10-25 parts of sodium dodecyl benzene sulfonate, 15-30 parts of sodium hexametaphosphate, 10-20 parts of triethanolamine, 10-20 parts of triisopropanolamine and the like. Without affecting a binder polyvinyl alcohol in preparation of the steatite ceramic pug, the product has a good grind-adding effect to the steatite ceramic pug, and the grinding time can be shortened from original 24-28 hours to at least 15-18 hours.

Description

technical field [0001] The invention relates to a material preparation technology, and further refers to a preparation and application technology of a composite grinding aid used in the slurry grinding process of steatite porcelain. Background technique [0002] Talc porcelain is a kind of natural mineral talc (a kind of hydrous magnesium silicate, the chemical formula is 3MgO 4SiO 2 ·H 2 O) prepared as the main raw material, with magnesium metasilicate (chemical formula MgSiO 3 ) Ceramic products with the main crystal phase. Talc is a common silicate mineral with a waxy luster, soft and delicate texture, and a smooth feeling to the touch. It generally has a flaky structure and tends to form flaky particles when broken. The talc in the blank is relatively easy to arrange in a certain direction during forming. Generally, pre-calcined talc is used, and the flake structure is destroyed by crushing, and then the ingredients are fed into the mill. However, the hardness of tal...
