Description

Technical Field

[0001] This invention relates to the field of concrete additive preparation technology, specifically a method for preparing high-strength concrete additives. Background Technology

[0002] Concrete additives are substances added to improve and adjust the performance of concrete. With the development of construction technology, the application of concrete additives in engineering has received increasing attention, and the use of additives has become a major measure to improve concrete performance. Water-reducing agents are concrete admixtures that can reduce the amount of mixing water while maintaining a relatively constant slump. Most of them are anionic surfactants, such as lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. After being added to concrete mixtures, they have a dispersing effect on cement particles, improving workability, reducing unit water consumption, improving the fluidity of concrete mixtures, or reducing unit cement consumption, thus saving cement.

[0003] Naphthalene sulfonate water-reducing agent was the first type used in my country. It is a product of naphthalene sulfonation with sulfuric acid followed by condensation with formaldehyde, and belongs to the anionic surfactant category. Depending on the product, this type of water-reducing agent can appear as a light yellow to dark brown powder. It is easily soluble in water and exhibits good dispersion of many powder materials such as cement, achieving a water reduction rate of up to 25%. The synthesis route of naphthalene sulfonate water-reducing agent is as follows: naphthalene → sulfonation → hydrolysis → condensation → neutralization → filtration → drying → product. Currently, the production process of existing water-reducing agents is quite cumbersome. The proportioning and addition of raw materials required for water-reducing agent manufacturing requires manual intervention, with materials added and mixed according to the actual manufacturing process. The entire operation is tedious and complex, prone to uneven proportioning, and cannot be packaged after preparation. Therefore, there is a need in the market for a concrete additive preparation process that achieves precise material proportioning during water-reducing agent preparation and allows for packaging after preparation.

The output end of the motor 8 drives the drive shaft 102, which is fixedly connected to it, to rotate. The drive shaft 102 drives the driving wheel 103 and the driving cylindrical cam 111, which are fixedly connected to it, to rotate. The driving wheel 103 drives the driven wheel 104 to rotate through the belt 105. The driven wheel 104 drives the reaction vessel 106, which is fixedly connected to it, to rotate. The reaction vessel 106 drives the stirring blade 107, which is fixedly connected to it. The heating element 108 rotates, and the heat emitted by the heating wire 108 melts the solid naphthalene in the reactor 106. The stirring blade 107 rotates to accelerate the flow of hot gas. After being heated, the solid naphthalene becomes liquid and flows into the naphthalene dissolving vessel 10. The reactor 106 drives the connecting frame 109, which is fixedly connected to it, to rotate. The connecting frame 109 drives the heating block 110 to rotate. The concentrated sulfuric acid in the sulfonation cylinder 4 enters the naphthalene dissolving vessel 10 and undergoes sulfonation with the liquid naphthalene.

The right connecting rod 202 drives the right compaction rod 205 fixedly connected to it to move up and down reciprocally. The right compaction rod 205 controls the right compaction block 208 to squeeze the formaldehyde-soaked sponge in the condensation cylinder 14. After being subjected to pressure, the sponge squeezes out the absorbed formaldehyde into the condensation cylinder 14, and then flows into the return liquid cylinder 15 through the connecting part 16, thereby realizing the condensation work with the reaction liquid.

[0043] B-Theasulfonic acid reacts with formaldehyde to form a naphthalene-based sulfonated formaldehyde condensate.

The condensed reaction liquid flows into the neutralization cylinder 17 through the return pipe 18. The liquid alkali neutralizes the excess sulfuric acid in the sulfonation reaction, thereby achieving the neutralization of the reaction liquid.

[0044] The neutralized reaction solution flows into the left slider 304 through the infusion tube 19. The left compaction rod 206 controls the left slider 304 to reciprocate back and forth through the left hinge rod 301. The left slider 304 controls the sealing plate 305 to intermittently add reaction solution to the packaging bottle 7. The left slider 304 drives the push rod 306 fixedly connected to it to reciprocate back and forth.
