The present invention relates to a method for producing detergent builder granules with a low bulk density suitable for blending into powdered detergents, powdered soaps, and the like. Detergent builders such as alkali metal carbonates, alkali metal sulfates, alkali metal condensed phosphates, and aluminosilicates (zeolites) are used as detergent auxiliary ingredients in detergents. Incorporation into detergents is carried out by uniformly mixing main components such as surfactants and auxiliary components such as detergent builders and other additives in a slurry state, and then spray drying or spray cooling to form powder. Although it is
In some cases, powdered carbonates and sulfates are blended into powdered detergents that have been granulated with carbonates and sulfates removed. However, commercially available powdered detergents have a small bulk density of about 0.3, whereas ordinary powdered carbonates have a bulk density of about 0.6 to 1.0. , so the amount of compounding is limited. Therefore, in order to incorporate a large amount of detergent builder into a powder-like detergent by powder blending, it is necessary to reduce the bulk density of the detergent builder. Methods for reducing the bulk density of powders such as carbonates include methods that utilize heated foaming of hydrated borates (Japanese Patent Publication No. 31-6528) and methods that utilize hydrated salts (Japanese Patent Publication No. 15911-1972). Publication No.) is known, but
Both methods are complicated to operate and are not practical. The inventors of the present invention have conducted intensive studies on a method for reducing the bulk density of a powdered detergent builder with a simple operation, and have found that by using sodium silicate and a liquid organic substance together as a binder, and further maintaining the granulation atmosphere temperature within a specific range, It was discovered that by adding and mixing with a powdered detergent builder, a granulated product having a low bulk density and good solubility and particle strength could be obtained, and based on this finding, the present invention was completed. That is, the method for producing a detergent builder of the present invention involves adding a sodium silicate aqueous solution and at least one liquid organic compound selected from cellulose derivatives, polyvinyl alcohol, and polyethylene glycol to a powdered detergent builder to produce a granulated product. It is characterized by granulation at a temperature of 50 to 70°C. Specific examples of detergent builders include alkali metal carbonate salts such as sodium carbonate, and alkali metal sulfate salts such as sodium sulfate. Sodium silicate used as a binder has a SiO 2 /Na 2 O ratio of 1.5/1 to 4/1. The liquid organic substance used in combination with the sodium silicate aqueous solution is an organic compound that is liquid at 70°C or lower, or an organic substance dissolved or dispersed in water with a temperature of 50 to 70°C.
It exhibits stickiness in the temperature range of °C, and specific examples of these include methylcellulose, hydroxymethylcellulose, hydroxyethylsethrose, carboxymethylcellulose sodium salt (CMC), polyvinyl alcohol (PVA), and polyethylene glycol (PEG). be. The two types of binders may be added separately or in a premixed state, and when added separately, there is no particular effect on the order of addition. The amount of (b) binder added to (a) powder detergent builder is preferably in the range of (a)/(b) = 80/20 to 40/60 in terms of weight ratio. The granulation atmosphere temperature needs to be maintained in the range of 50°C to 70°C. If the temperature is lower than 50℃, the moisture in the binder will not evaporate sufficiently, causing coarse condensation of the powder, or
This is not preferable because it becomes difficult to ensure a low bulk density. On the other hand, if the temperature exceeds 70℃, the moisture in the binder will evaporate too quickly and granulation will occur before the binder is evenly mixed with the powder, making it difficult to obtain uniform granules, which is undesirable. . Granulation is carried out using an aqueous solution of sodium silicate and a liquid organic compound as a binder, and the specific method is not critical. Liquid organic compounds such as sodium aqueous solution and carboxymethyl cellulose sodium aqueous solution are sprayed from above and agglomerated and granulated while maintaining the granulation atmosphere temperature in the range of 50°C to 70°C by adjusting the hot air temperature, hot air volume, and binder amount. That's fine. Example 1 Bulk density 0.6 g/cc in a fluidized bed dryer with variable hot air temperature of 150°C to 250°C (fluidized air speed 0.8 to 1.2 m/sec)
of sodium carbonate powder, and add sodium silicate aqueous solution (SiO 2 /Na 2 O = 2.2/1, concentration
45wt%) and carboxymethylcellulose sodium (CMC) aqueous solution (carboxymethylcellulose sodium with degree of etherification 0.5-0.6, concentration
While spraying 5wt%), the granulation atmosphere temperature was set to 55℃.
The temperature was kept constant and the treatment was carried out for about 20 minutes to obtain granules. Example 2 In the same manner as in Example 1, the granulation atmosphere temperature was set to 60°C.
The mixture was granulated at controlled temperature to obtain a granulated product. Example 3 In the same manner as in Example 1, sodium carboxymethyl cellulose (CMC) powder (degree of etherification 0.5 to 0.6) was added to an aqueous sodium silicate solution (SiO 2 /Na 2 O = 2.2/1, concentration 45 wt%) as a binder. Added sodium silicate/CMC=8/2, concentration 50%
Using a mixed aqueous solution of
Granules were obtained by controlling the temperature to 60°C. Example 4 In the same manner as in Example 2, a sodium silicate aqueous solution (SiO 2 /Na 2 O = 2.2/1, concentration 45 wt%) and a hydroxyethyl cellulose (HEC) aqueous solution [HEC: Unicel (manufactured by Daicel Chemical Industries, Ltd.]) were used as binders. :, concentration 4wt%] to obtain a granulated product. Example 5 In the same manner as in Example 2, a sodium silicate aqueous solution (SiO 2 /Na 2 O = 2.2/1, concentration 45 wt%) and polyvinyl alcohol (PVA) were used as binders.
Aqueous solution [degree of saponification 80 to 90 mol% partial saponification]
PVA (manufactured by Nippon Gosei Kagaku, concentration 7wt%) was used to obtain a granulated product. Example 6 In the same manner as in Example 2, a sodium silicate aqueous solution (SiO 2 /Na 2 O = 2.2/1, concentration 45 wt%) and polyethylene glycol (PEG) were used as binders.
Granules were obtained using an aqueous solution (PEG with an average molecular weight of 1000, manufactured by Lion Chemical Co., Ltd., concentration 50%). Example 7 Bulk density 1.1 g/cc in a fluidized bed dryer with variable hot air temperature of 150°C to 250°C (fluidized air speed 1.0 to 1.5 m/sec)
Example 1
While spraying the same binder of sodium silicate aqueous solution and CMC aqueous solution, the granulation atmosphere temperature was set to 60°C.
The mixture was granulated at controlled temperature to obtain a granulated product. Comparative example By the same operation as in Example 1, the granulation atmosphere temperature was set to 45
The mixture was granulated at controlled temperature to obtain a granulated product. Table 1 shows the composition, bulk density, particle strength, and solubility (dissolution residue) of the granules obtained in Examples 1 to 7 and Comparative Example above when dissolved in water.

4wt% (5) PVA aqueous solution; partially saponified polyvinyl alcohol (manufactured by Nippon Gosei Kagaku) with saponification degree of 80 to 90 mol%, concentration 7wt% (6) PEG aqueous solution; polyethylene glycol with an average molecular weight of 1000 (manufactured by Lion Chemical), concentration 50wt% In the table, the spray amount is parts by weight based on 100 parts of powder detergent builder. The particle strength was determined by the change in bulk density when 160 c.c. of the granulated material was placed in a 200 c.c. container and vibrated for 50 minutes. To remove the dissolved residue, leave the granules in a carbon dioxide atmosphere for 8 hours, then put the granules in a washing machine containing water at 5°C to give a concentration of 0.266% by weight. After stirring for 5 minutes, the solution was washed with 150 meshes. This value was determined by the following formula by passing it through a sieve. Dissolution residue (%) = 150 mesh remaining amount / granulated sample amount x 100
