Problems solved by technology

At present, there are many processing methods for polycarboxylate superplasticizers. In the conventional process, the material is dissolved for about 30 minutes, other components are added dropwise for about 180 minutes, the heat preservation reaction is about 60 minutes, and the water is replenished and stirred for about 10 minutes. The processing time is too long. It also needs to be heated (50°C-60°C), which has the problems of low production efficiency and long processing time

Embodiment 1

[0034] A processing method of a polycarboxylic acid high-performance water reducer, comprising the following steps: according to the materials required for production, a one-time feeding method is adopted;

[0035] (1) Dissolving material; put deionized water, polyether monomer and hydrogen peroxide into a 10000L stainless steel open reaction kettle for dissolving for 10 minutes until melting;

[0036] (2) Ingredients; for ingredient A, put deionized water and acrylic acid into 2000L metering tank A, stir and dissolve for 10 minutes until completely melted; for ingredient B, put deionized water, mercaptopropionic acid, and VC into 2000L metering tank In B, stir and dissolve for 10 minutes until completely melted;

[0037] (3) Add the prepared material A and material B to the reactor at a constant speed and dropwise for 30 minutes at the same time;

[0038] (4) After adding material A and material B, heat and stir for 30 minutes.

Abstract

The invention discloses a processing method of a polycarboxylic acid high-performance water reducing agent. The processing method comprises the following steps: (1) dissolving materials; adding deionized water, a polyether monomer and hydrogen peroxide into a reaction kettle, and dissolving until melting; (2) burdening; preparing a material A, putting deionized water and acrylic acid into a metering tank A, and stirring and dissolving until the deionized water and the acrylic acid are completely molten; preparing a material B, adding deionized water, mercaptopropionic acid and VC into a metering tank B, and stirring and dissolving until the materials are completely molten; (3) dropwise adding the prepared material A and material B into the reaction kettle at the same time; and (4) after the material A and the material B are added, performing heat preservation and stirring. The method has the advantages that the obtained product is good in quality, the processing time can be greatly shortened, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of water reducer processing, and in particular relates to a processing method and a processing device of a polycarboxylate high-performance water reducer. Background technique [0002] Polycarboxylate superplasticizer is a concrete superplasticizer, which can significantly improve the durability, strength and fluidity of concrete. At present, there are many processing methods for polycarboxylate superplasticizers. In the conventional process, the material is dissolved for about 30 minutes, other components are added dropwise for about 180 minutes, the heat preservation reaction is about 60 minutes, and the water replenishment is stirred for about 10 minutes. The processing time is too long. It also needs heating (50°C-60°C), which has the problems of low production efficiency and too long processing time. Contents of the invention [0003] In view of the above problems, the purpose of this invention is to...
