Embodiment Construction

[0020] According to the mass ratio, put 100 parts of polyethylene glycol ether into a pressurized and heated reactor, then add 10 parts of powdered sucrose, stir evenly, then raise the temperature to 110 ° C, cover and pressurize to 10 MPa, and react Treat for 1 hour, and then pass cooling water into the water jacket of the reactor to cool the reactant to room temperature, pour it out, and become a sucrose-modified polyethylene glycol ether.

[0021] The polyethylene glycol ether is also called polyether.

[0022] The addition amount of the sucrose modified polyethylene glycol ether in the cement grinding aid is 3-5% by mass percentage.

[0023] In cement grinding aids, polyglycol ether viscosity characteristics, viscosity characteristics, low temperature fluidity, lubricity, thermal oxidation stability and water-soluble and oil-soluble characteristics are used, and the retarding effect of sucrose is used, so it can be used in During the grinding process of cement clinker, th...

Abstract

The invention discloses a method for producing cane sugar modified polyglycol ether. The method comprises the following steps: adding 100 parts of polyglycol ether into a pressurizing and heating reactor, subsequently adding 10 parts of powder cane sugar, uniformly stirring, rising the temperature to be 11 DEG C, covering and pressurizing to be 10MPa, reacting and treating for 1 hour, subsequently introducing cooling water into a water jacket of the reactor so as to reduce the temperature of the reactant to be the room temperature, and pouring out so as to obtain the cane sugar modified polyglycol ether. The addition amount of the modified polyglycol ether in a cement grinding aid is 10-15% in percentage by mass. The cane sugar modified polyglycol ether is used as a raw material of the cement grinding aid. The cane sugar modified polyglycol ether has the advantages of lubrication, lubrication, cement activity improvement, cement strength improvement and cement grinding property improvement, and is applicable to application as the raw material of the cement grinding aid.

Description

technical field [0001] The invention proposes a grinding aid for cement grinding, specifically a production method of sucrose modified polyethylene glycol ether. Background technique [0002] Polyether, also known as polyethylene glycol ether, is currently the most sold synthetic oil. It is a linear polymer prepared by ring-opening homopolymerization or copolymerization with ethylene oxide, propylene oxide, butylene oxide and tetrahydrofuran as raw materials under the action of a catalyst. [0003] A class of polymers with ether groups as structural characteristic groups in complex units. It is an important raw material for the production of polyurethane, and has multiple functions such as defoaming, demulsification, dispersion, penetration, and emulsification. [0004] characteristic: [0005] 1 viscosity characteristics; [0006] 2 Viscosity and pressure characteristics; [0007] 3 low temperature fluidity; [0008] 4 Lubricity; [0009] 5 thermal oxidation stabilit...
