Embodiment 1

[0026] The ultrafine composite mineral admixture grinding aid provided in this example includes raw materials including 30 wt% of modified polyhydric alcohol amine, 20 wt% of molasses, 3 wt% of calcium chloride, and 47 wt% of water.

[0027] The preparation method of the modified polyhydric alcohol amine is as follows: add 25wt% of triethanolamine, 40wt% of maleic anhydride, and 35wt% of polyethylene glycol 200 into a reaction vessel, stir evenly, heat up to 110°C, and keep the temperature for 1h , After cooling, the modified polyhydric alcohol amine is obtained.

Embodiment 2

[0029] The difference between the ultrafine composite mineral admixture grinding aid provided in this example and Example 1 is that its raw materials include 40wt% of modified polyhydric alcohol amine, 20wt% of molasses, 3wt% of calcium chloride, and 37wt% of water.

Embodiment 3

[0031] The difference between the ultrafine composite mineral admixture grinding aid provided in this example and Example 1 is that its raw materials include 20wt% of modified polyhydric alcohol amine, 40wt% of molasses, 3wt% of calcium chloride, and 37wt% of water.

Abstract

The invention discloses a superfine composite mineral admixture grinding aid and a preparation method thereof. The raw materials include 20-40wt% of modified polyhydric alcohol amine, 20-40wt% of sugar, 1-10wt% of inorganic salt, and the balance It is water; the preparation method of the modified polyhydric alcohol amine is: adding 20-30wt% of alcoholamine, 30-50wt% of acid anhydride, and 20-40wt% of alcohol into a reaction vessel and stirring evenly, heating to 105-120°C, Heat preservation reaction for 1-2h, and obtain modified polyhydric alcohol amine after cooling. The superfine composite mineral admixture grinding aid of the present invention is specially researched and developed based on the physical and chemical properties, particle size distribution, composition and other characteristics of the ultrafine composite mineral admixture. The specific surface energy of ultra-fine admixture particles reduces agglomeration; it not only has an excellent grinding aid effect, but also takes into account the activity enhancement effect, which improves the workability, fluidity and cohesiveness of the admixture when used; shortens the grinding time More than 30%, product fineness D 50 Decrease, the specific surface area of ​​the product increases.

Description

technical field [0001] The invention belongs to the field of grades of cement concrete building materials, in particular to an ultrafine composite mineral admixture grinding aid. Background technique [0002] At present, in the field of building materials, especially in the field of cement and concrete, ultrafine composite mineral admixtures have been widely used, and their market demand is also increasing. The powder particle size of the ultra-fine composite mineral admixture currently flowing in the market is extremely fine, and its median diameter D50 is generally less than 6.5 μm. The processing method is generally to increase the specific surface area to 400m 2 / kg of mixed material is ground to a specific surface area of ​​700-800m 2 / kg, which involves a process of grinding powder to ultrafine powder. [0003] Grinding aid is the most common admixture in powder processing. Its function is to promote the grinding process and improve the grinding efficiency, so as to ...
