preparation example Construction

[0025] The preparation method of the composite high-efficiency liquid cement grinding aid, comprising:

[0026] (1) 6-8 parts of triethanolamine, 2-4 parts of wax emulsion, 2-4 parts of sodium silicate, and 20 parts of water are stirred in a high-speed homogenizer for 5-10 minutes to obtain compound solution 1;

[0027] (2) 2-4 parts of polyetheramine, 2-4 parts of water-soluble acrylic resin, 10-20 parts of ethylene glycol, 3-5 parts of polycarboxylic acid, and 5-7 parts of molasses are mixed evenly, and ultrasonically dispersed to obtain a compound liquid 2;

[0028] (3) Slowly add compound solution 2 to compound solution 1 dropwise, stir rapidly while adding dropwise, and continue to disperse for 10 minutes after the dropwise addition is completed.

Embodiment 1

[0030] A composite high-efficiency liquid cement grinding aid, wherein, in parts by mass, the composite liquid 1 comprises: 7 parts of triethanolamine, 3 parts of wax emulsion, and 3 parts of sodium silicate , 20 parts of water; the compound solution 2 includes: 3 parts of polyetheramine, 3 parts of water-soluble acrylic resin, 15 parts of ethylene glycol, 4 parts of polycarboxylic acid, and 6 parts of molasses.

[0031] The ratio of the compound solution 1 to the compound solution 2 is 2.6:1.

[0032] The wax emulsion is polyethylene wax emulsion.

[0033] The polyetheramine is an amino-terminated polyoxyethylene ether with a molecular weight of 200-300.

[0034] The polycarboxylic acid is a trivalent polycarboxylic acid.

[0035] The preparation method of the composite high-efficiency liquid cement grinding aid, comprising:

[0036] (1) stirring triethanolamine, wax emulsion, sodium silicate, and water in a high-speed homogenizer for 7.5 minutes to obtain compound solutio...

Embodiment 2

[0040] A composite high-efficiency liquid cement grinding aid, the composite high-efficiency liquid cement grinding aid is composed of a composite solution 1 and a composite solution 2; in parts by mass, the composite solution 1 includes: 6 parts of triethanolamine, wax 4 parts of emulsion, 2 parts of sodium silicate, 20 parts of water; the compound solution 2 includes: 4 parts of polyetheramine, 2 parts of water-soluble acrylic resin, 20 parts of ethylene glycol, 3 parts of polycarboxylic acid, and 7 parts of molasses .

[0041] The ratio of the compound solution 1 to the compound solution 2 is 2.4:1.

[0042] The rest is the same as in Example 1.

Description

【Technical field】 [0001] The invention belongs to the technical field of building materials, and in particular relates to a composite high-efficiency liquid cement grinding aid and a preparation method thereof. 【Background technique】 [0002] Cement is an indispensable building material in the development of the national economy, and it is also one of the artificial building materials with the largest output in the world. At the same time, the per capita usage of cement is also an important indicator to measure whether a country is developed. Cement plays a very important role in the development and progress of human civilization. According to the current development of the world's scientific and technological level, there is no building material that can replace cement in a short period of time. [0003] In the process of cement production, the power consumption for raw meal preparation and cement grinding accounts for more than 70% of the total power consumption. Judging ...
