Trichloroiminocyanuric acid effervescent tablet and preparation method thereof

Abstract

The invention discloses a trichloroisocyanuric acid effervescent tablet and a preparation method thereof. The trichloroisocyanuric acid effervescent tablet comprises raw materials of, by weight, 46-50% of trichloroisocyanuric acid, 18-23% of cyanuric acid, 14-17% of cyanuric acid, 2-5% of boric acid, 5-8% of sodium benzoate, 1-2% of polyvinylpyrrolidone, 0.2% of sodium dodecyl sulfate, 1.5% of anhydrous citric acid and 0.3% of carboxymethylcellulose sodium. The preparation method comprises steps of: (1) raw material screening: sieving trichloroisocyanuric acid, sodium carbonate, cyanuric acid and boric acid, separating adhesive particles and removing large particles or hard block; (2) mixing well the raw materials; (3) crushing the materials; (4) placing sodium benzoate into a mixture to obtain a standby material; (5) granulating the standby material to obtain a granular standby material; (6) adding polyvinylpyrrolidone, sodium dodecyl sulfate, anhydrous citric acid and carboxymethylcellulose sodium into the standby material and mixing well for reservation; (7) compacting the materials to obtain the trichloroisocyanuric acid effervescent tablets.

Description

technical field [0001] The invention relates to trichloroisocyanuric acid, which is a trichloroisocyanuric acid effervescent tablet and a preparation method thereof. Background technique [0002] Trichloroisocyanuric acid is a very strong oxidizing agent and chlorinating agent. It has high-efficiency, broad-spectrum, and safe disinfection. It has a killing effect on bacteria, viruses, fungi, and spores. It is widely used in the environment, drinking water, Disinfection in many fields such as animal breeding. Because the powder of trichloroisocyanuric acid has deficiencies such as inconvenient transportation and poor chlorine constant effect, single and compound tablets of trichloroisocyanuric acid are widely used. However, it is found in use that although the available chlorine content of the single tablet is as high as 90%, its pH value is low, the solubility is small, and the dissolution rate in water is slow. In order to solve the above problems, those skilled in the art...

AI Technical Summary

Problems solved by technology

Yet find in use, although the available chlorine content of unilateral tablet is up to 90%, its pH value is lower, and solubility is little, and the dissolving speed in water is slower, in order to solve the above problems, those skilled in the art provide compound tablet

The disclosed compound tablets are generally made of raw materials such as trichloroisocyanuric acid, sodium bicarbonate and organic acids, but the effervescence effect is not good, the product decomposes seriously during storage, and the constant chlorine effect in the main technical indicators is poor , affecting the disinfection effect of the product
