preparation example Construction

[0042] The present invention provides the preparation method of cement grinding aid described in above technical scheme, comprises the following steps:

[0043] First mixing deionized water, triethanolamine, diethanol monoisopropanolamine, polycarboxylic acid, sodium gluconate and polyethylene glycol at room temperature to obtain a mixed material liquid;

[0044] The mixture liquid is heated to 90-95° C. for the second mixing to obtain the cement grinding aid.

[0045] In the present invention, deionized water, triethanolamine, diethanol monoisopropanolamine, polycarboxylic acid, sodium gluconate and polyethylene glycol are first mixed at normal temperature to obtain a mixed material liquid. In the present invention, the first mixing method is preferably: adding triethanolamine, diethanol monoisopropanolamine, polycarboxylic acid, sodium gluconate and polyethylene glycol to deionized water in sequence, and after adding each raw material Stirring and mixing; the speed of each ...

Embodiment 1

[0061] (1) Inject metered normal temperature deionized water into the reactor;

[0062] (2) Meteringly inject industrial grade triethanolamine into the reaction kettle, stir and mix for 20min at a stirring speed of 15r / min;

[0063] (3) Metering industrial-grade diethanol monoisopropanolamine into the reactor, stirring and mixing for 20 minutes at a stirring speed of 15 r / min;

[0064] (4) Metering industrial-grade polycarboxylic acid into the reactor, stirring and mixing for 20 minutes at a stirring speed of 15 r / min;

[0065] (5) Meteringly inject industrial grade sodium gluconate into the reaction kettle, stir and mix for 20min at a stirring speed of 15r / min;

[0066] (6) Metering industrial-grade polyethylene glycol amine into the reactor, stirring and mixing for 20 minutes at a stirring speed of 15 r / min;

[0067] (7) The mixture was heated to 95°C and stirred at a stirring speed of 15r / min for 2h;

[0068] (8) Naturally cool to room temperature to obtain a decoration ...

Embodiment 2

[0071] Refer to the steps of Example 1 to prepare the decoration cement grinding aid, the difference is that the mass ratio of deionized water, triethanolamine, diethanol monoisopropanolamine, polycarboxylic acid, sodium gluconate, and polyethylene glycol is shown in the table 1. The pH value of the prepared decoration cement is 8-10.

Abstract

The invention provides a cement grinding aid and a preparation method and application thereof in interior decoration cement, and relates to the technical field of building materials. The cement grinding aid provided by the invention comprises the following components in percentage by mass: 11-15% of triethanolamine, 11-15% of diethanolisopropanolamine, 14-16% of polycarboxylic acid, 5-6% of sodiumgluconate, 5-6% of polyethylene glycol and the balance of deionized water, wherein the pH value of the cement grinding aid is 8.0 to 10. By controlling the composition and content of raw materials, the cement grinding aid provided by the invention not only has a good cement grinding aid effect, but also has reinforcing, air-entraining, water-reducing and retarding effects, and can effectively improve the workability, flowability and cohesiveness of cement, so that the cement meets the construction requirements of interior decoration; in addition, the cement grinding aid provided by the invention is non-toxic, pollution-free, green and environment-friendly, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cement grinding aid, a preparation method thereof and an application in interior decoration cement. Background technique [0002] Building interior decoration works need to use a large amount of cement. Due to the different nature of interior decoration engineering and building structure engineering, there are also obvious differences in the quality requirements of cement used in the two: building structure engineering emphasizes the mechanical properties and durability of cement, while interior decoration engineering requires less mechanical and durable performance of cement. It is not too high, but it has high requirements on the workability, fluidity, air-entraining property and cohesiveness of cement. In order to meet this demand, in recent years, many cement production enterprises have begun to study cement specially used for interior decoration (referred to as...
