Problems solved by technology

These dispersants have disadvantages such as narrow dissolving range, easy solidification in a short time, poor adaptability and side effects.
A small number of ceramic enterprises use organic dispersants and inorganic dispersants in combination. Although it can achieve certain effects, the dispersants developed are not universal and cannot be applied to various clay mineral raw materials, so it is difficult to popularize and use them.

preparation example Construction

[0026] A kind of preparation method of bamboo tar series ceramic dispersant, realizes by following steps:

[0027] (1) After adding bamboo tar, triphenol, glucose allylamide and alkaline regulator and water into the reaction kettle, start heating and heating, and when the temperature rises to 85-100°C, start stirring;

[0028] (2) Slowly add formaldehyde, the dropping time is controlled within 1-3 hours, and the temperature is controlled at 85-120°C during the dropping. After the dropping is completed, add phosphorus-containing compounds and unsaturated glycidyl esters, and then start dropping the mass percentage An initiator solution with a concentration of 1-10%, which is prepared from the initiator and part of the water, the dropping time is controlled within 0.5-3 hours, and the temperature during the dropping is controlled at 85-130°C;

[0029] (3) After adding, keep warm for 1 to 5 hours, then cool down and discharge to obtain the bamboo tar-based ceramic dispersant.

Embodiment 1

[0032] A kind of bamboo tar series ceramic dispersant, is made of the raw material component of following parts by weight ratio:

Abstract

The invention provides a bamboo tar-based ceramic dispersant and a preparation method thereof. The steps are as follows: (1) after adding bamboo tar, trisphenol, glucosyl amide, an alkaline regulator and water into a reaction kettle, start heating Heat up, when the temperature rises to 85~100 ℃, turn on stirring; (2) slowly add formaldehyde dropwise, the dropping time is controlled at 1~3 hours, and the temperature is controlled at 85~120 ℃ during the dropwise addition, after the dropwise addition, add the Phosphorus compound, unsaturated glycidyl ester, and then start to drop an initiator solution with a mass percentage concentration of 1-10%, this initiator solution is prepared from the initiator and part of the water, and the dropping time is controlled at 0.5 ~3 hours, the temperature is controlled at 85~130 ℃ during the dropwise addition; (3) after adding, keeping the temperature for 1~5 hours, cooling down and discharging, namely, the bamboo tar-based ceramic dispersant is obtained.

Description

technical field [0001] The invention relates to the technical field of ceramic dispersants, in particular to a bamboo tar-based ceramic dispersant and a preparation method thereof. Background technique [0002] Ceramic dispersant, also known as ceramic decoagulant, debonding agent, water reducer and diluent, etc., as a kind of ceramic additive, its main function is to destroy the flocculation structure of ceramic slurry particles, so that the slurry can It still has better dispersibility and lower viscosity. Under the premise of ensuring the proper fluidity and viscosity of the mud, minimizing the water content of the mud is the most important means of saving energy and reducing consumption. The use of dispersants with excellent performance in ceramic production can reduce the production cost of ceramics, improve product quality, and make the ceramic production industry develop in the direction of high efficiency, good quality and low energy consumption. [0003] At presen...
