Embodiment 1

[0016] Embodiment 1: A cement grinding aid, which is prepared by the following method: put metal-organic framework material UIO-66, castor oil, butyl naphthalene sulfonate and sodium lauryl sulfate into water, and disperse evenly ; Add triethanolamine and molasses to the water dispersion, disperse evenly, add apple juice and disperse evenly;

[0017] The mass ratio of water, triethanolamine, molasses, apple juice, metal-organic framework material UIO-66, castor oil, butyl naphthalene sulfonate and sodium lauryl sulfate is 100:22:3:7:9:4 : 1.5: 3; the total sugar content of molasses is 42wt% in terms of converted sugar content.

Embodiment 2

[0018] Embodiment 2: a kind of cement grinding aid, the difference with embodiment 1 is that water, triethanolamine, molasses, apple juice, metal-organic framework material UIO-66, castor oil, butyl naphthalene sulfonate and The mass ratio of sodium lauryl sulfate is 100:20:2:6:8:3:1:2; the total sugar content of molasses is 40wt% in terms of converted sugar content.

Embodiment 3

[0019] Embodiment 3: a kind of cement grinding aid, the difference with embodiment 1 is that water, triethanolamine, molasses, apple juice, metal-organic framework material UIO-66, castor oil, butyl naphthalene sulfonate and The mass ratio of sodium lauryl sulfate is 100:25:4:8:10:5:2:4; the total sugar content of molasses is 45wt% in terms of converted sugar content.

Abstract

The invention discloses a cement grinding aid and a preparation method thereof. The cement grinding aid is prepared from water, triethanolamine, molasses, apple juice, a metal-organic framework material UIO-66, castor oil, butyl naphthalene sulfonate and lauryl sodium sulfate, wherein a mass ratio of the water to the triethanolamine to the molasses to the apple juice to the metal-organic frameworkmaterial UIO-66 to the castor oil to the butyl naphthalene sulfonate to the lauryl sodium sulfate is 100 to (20 to 25) to (2 to 4) to (6 to 8) to (8 to 10) to (3 to 5) to (1 to 2) to (2 to 4). According to the conversion sugar amount, the total sugar amount of the molasses is 40 to 45wt%. The cement grinding aid has the advantage of improving freezing resistance.

Description

technical field [0001] The invention relates to a cement grinding aid and a preparation method thereof. Background technique [0002] The low frost resistance of concrete limits its application. At present, the main way to improve the frost resistance of concrete is to add slag to it. It is still of great significance to develop another method to improve the frost resistance of concrete. Contents of the invention [0003] The first object of the present invention is to provide a cement grinding aid which has the advantage of improving frost resistance. [0004] Above-mentioned technical purpose of the present invention is achieved through the following technical solutions: [0005] A cement grinding aid comprising water, triethanolamine, molasses, apple juice, metal-organic framework material UIO-66, castor oil, butyl naphthalene sulfonate and sodium lauryl sulfate; water, triethanolamine, molasses , apple juice, metal-organic framework material UIO-66, castor oil, but...
