Efficient preparation process of thickening agent

Abstract

The invention discloses an efficient preparation process of a thickening agent, and belongs to the field of preparation of thickening agents. In the preparation process, mechanical stirring in the prior art is replaced by pneumatic stirring operation, and by circulating inflation and exhaust operation; the stirring effect of fountain type rising-falling-falling-rising of the fountain type pneumatic strip in raw materials is achieved, overflow of internal air is effectively accelerated under the condition that external air is effectively prevented from being introduced, then the preparation efficiency is improved, meanwhile, when the fountain type pneumatic strip falls back, shrinkage pieces can also be tightly attached to the inner wall of a bearing plate, at the moment, the surface tension of the two is greatly changed, bubbles adsorbed on the surfaces of the two are exploded, the situation that the bubbles adsorbed on the inner wall of a container are difficult to eliminate in the prior art is effectively avoided, overflow of the bubbles in the raw materials is further accelerated, the air content in the finished product of the thickening agent is effectively reduced, and the quality of the finished product of the thickening agent is better.

Description

technical field [0001] The invention relates to the field of thickener preparation, in particular to a high-efficiency thickener preparation process. Background technique [0002] Thickener is a kind of rheological additive, which can not only thicken the coating and prevent sagging during construction, but also endow the coating with excellent mechanical properties and storage stability. It is a very important class of additives for water-based paints with low viscosity. There are water and oily points. Especially the application of water phase thickener is more common. Thickener is essentially a kind of rheological additive. After adding thickener, it can adjust rheology, thicken adhesive and sealant, prevent filler from settling, endow good physical and mechanical stability, and control flow during construction. Denaturation (no sagging, no dripping, no flying liquid when sizing), can also play a role in reducing costs. It is especially important for the manufacture, ...

AI Technical Summary

Problems solved by technology

[0003] However, during the preparation of the thickener, certain air bubbles are usually produced inside it, which affects the use effect of the thickener in the coating. In the prior art, the air bubbles are generally taken out by heating and stirring, but during the heating process, The dissociated air bubbles are generally easily adsorbed on the inner wall of the container, and it is difficult to overflow in time, and it is easy to introduce outside air during stirring, resulting in poor removal of air in the thickener
