Embodiment 1

[0017] Weigh 30kg of acrylic acid, 4.5kg of sodium bisulfite, 4.5kg of sodium hydroxide, 0.06kg of ammonium persulfate, 10kg of starch, and 50.94kg of deionized water.

[0018] Take sodium hydroxide and deionized water to prepare a 15% sodium hydroxide solution.

[0019] Add deionized water to the reaction kettle, then add the chain transfer agent sodium bisulfite, stir, heat up to 65°C, add acrylic acid, then start to add ammonium persulfate dropwise, finish adding within 3 hours, then add starch, and control the temperature at 65°C Stir at ℃ for 3 hours, then add 15% sodium hydroxide solution, the pH of the solution is 7.2, and a colorless viscous paste is obtained.

[0020] Dry the paste at 60°C for 30 minutes, with a water content of 8%. The resulting solid is crushed and passed through an 80-mesh sieve to obtain a thickened water-retaining agent.

[0021] The invention discloses a thickening and water-retaining agent. The thickening and water-retaining agent comprises 30...

Abstract

The invention discloses a thickening and water retention agent. The thickening and water retention agent is prepared from 30 parts by weight of acrylic acid, 4.5 parts by weight of sodium bisulfite, 4.5 parts by weight of sodium hydroxide, 0.06 part by weight of ammonium persulfate, 10 parts by weight of starch and 50.94 parts by weight of deionized water, which serve as raw materials, through firstly, dissolving sodium bisulfite in the deionized water, then, adding acrylic acid and ammonium persulfate into the solution, then, adding the starch into the solution, finally, adding a sodium hydroxide solution so as to obtain colorless viscous paste, and subjecting the paste to drying, crushing and sieving, wherein the temperature of a reaction process is controlled to 65 DEG C. The thickening and water retention agent has the functions of water retention, retarded setting, thickening and anti-settling, the production cost is low, and the use cost is low, so that the thickening and water retention agent is suitable for being extensively applied to concrete, white leveling cement, mortar, paint and putty.

Description

technical field [0001] The invention relates to a thickening and water-retaining agent, which belongs to a functional regulator and can be applied to concrete, paint, putty and other materials. Background technique [0002] Thickening and water-retaining agent is a commonly used functional regulator, which is used in many fields such as concrete and coatings to improve the performance of materials. The currently used thickening and water-retaining agent has a high cost and needs to be added in a large amount, resulting in a high application cost, which needs to be further improved. Contents of the invention [0003] The purpose of the present invention is to provide a functional regulator, which has the functions of water retention, retardation, thickening and anti-settling. [0004] In order to achieve the above object, the inventor provides the following technical solutions. [0005] A kind of thickening water-retaining agent, its preparation method comprises the follo...
