Description

[Title of the Invention]

Powder detergent composition using an absorber and method of manufacturing the same

DETAILED DESCRIPTION OF THE INVENTION [

[Object of the invention]

The present invention relates to a powder detergent composition using an absorber and a method for producing the same. More specifically, in the present invention, a certain level of absorber is first prepared, and the resulting mixture is placed in a mixer having a vertical and horizontal stirring shafts. Then, one or more kinds of liquid interface components are added and stirred to form particles of a predetermined size, To a method for producing a powder detergent having uniform particle distribution.

[TECHNICAL FIELD OF THE INVENTION AND RELATED ART OF THE SAME]

In the conventional method of producing a powder detergent, the content of anionic surfactant is high, so that the state of dry particles dried by the countercurrent spray drying apparatus in the neutralization tank is moist, the size is uneven, and the surface which is very weak in moisture is often seen have. Therefore, a high speed mixer (L digester mixer or Schugi mixer), pulverized, sprayed with a liquid material to form contact points with pulverized dry particles, and then applied with a water insoluble material such as zeolite or talc to form a large mass (hereinafter referred to as " rum " And the particle size is not uniform. It is difficult to produce liquid components such as non-ionic surfactant components in the concentration and process (see, for example, Japanese Patent Application Laid-Open Nos. 61-69900, 61-69898, 78-43710, (P. 4-5080)].

[Technical Problem]

The present inventors have conducted numerous studies and experiments to solve the problems of the prior art described above. As a result, they have found that by absorbing the active ingredient of a liquid component using an absorber in a high-speed rotary granulator, A powder detergent can be prepared, and the present invention has been completed.

[Structure and operation of the invention]

The present invention relates to a high speed mixer or a high speed mixer dige mixer or Schugi mixer), 10 to 30 parts by weight of a liquid active ingredient is sprayed to form particles, and 10 to 30 parts by weight of a surface modifier is added to modify the surface of the powder detergent. .

According to the present invention, an absorber is manufactured first, and then a high speed mixer or L dige mixer or Schugi mixer), the liquid active ingredient is sprayed with stirring to form particles while absorbing the liquid component. And then adding a surface modifier to improve the physical properties of the surface to prepare a powder detergent.

In the present invention, the absorber is neutralized by adding 10 parts by weight of the alkyl benzene sulfonate, 12 parts by weight of the fatty acid salt, and 8 parts by weight of the alpha olefin sulfonic acid salt. The content of the total anionic surfactant is 10 to 26 parts by weight. 10 to 80 parts by weight of sodium carbonate (Na ₂ CO ₃ ) and / or potassium carbonate (K ₂ CO ₃ ) used as an alkali builder (A / B 3 in case of mixture, A is sodium carbonate and B is potassium carbonate) 0 to 20 parts by weight of sodium hydrogen (NaHCO ₃ ), 15 parts by weight of sodium silicate, and 5 parts by weight or less of a polymeric substance such as polyacrylic acid or its salt are used to prepare a neutralized slurry. Wherein the solids content of the slurry is 40 to 60 parts by weight. Where the solids content is the portion by weight of the solid portion of the slurry comprised of water and the absorber source component. Then, an absorber powder having a moisture content of less than 5% is prepared using a countercurrent drier.

The apparent density of the absorber obtained in the present invention is 0.4 to 0.70 g / cm ³ . 10 to 30 parts by weight of a liquid active ingredient (a / b5, a: fatty alcohol polyoxyethylene glycol ether and / or fatty acid polyoxyethylene glycol ether and b: polyoxyethylene glycol) is added to 40 to 70 parts by weight of the absorber obtained in this way , Preferably 10 to 20 parts by weight, is mixed with a high speed mixer or a high speed mixer dige mixer or Schugi mixer) to form particles. At this time, the particles will exhibit sticky properties as the absorber absorbs the liquid component, but the base particles will be uniform. After the particles are formed, the particles are cured for 5 to 8 minutes, and then 10 to 30 parts by weight of a surface modifier (at least one selected from powdered zeolite, talc, clay and silica) is added thereto to improve the surface smoothness And the detergent particles having a very uniform powder particle size can be produced. And the distribution of the prepared powder particles shows that the amount between the passage of 14 mesh of normal net and the passage of 25 mesh of water is 50% or more.

And the apparent density of the detergent prepared by the method of the present invention is 0.6 to 1.0 g / cm ³ .

In the present invention, a surface active agent of anionic surfactants used as a main component of the detergent material is linear alkyl benzene sulfonate _{(R1-CH 2 -SO 3 Na} : R 1 = C 9 ~C 15 alkyl); Fatty acid salts (R ₂ -CH ₂ -COONa: R ₂ = C ₁₁ -C ₁₆ alkyl); Alkanesulfonate (R ₃ = CH-SO ₃ Na: R ₃ = C ₁₁ -C ₁₈ alkyl); And at least one selected from alpha olefin sulfonic acid salts (R ₄ -CH = CH-CH ₂ -SO ₃ Na: R ₄ = C ₁₂ -C ₁₈ alkyl).

Examples of the nonionic surfactant include fatty alcohol polyoxyethylene glycol (R ₅ -CH- (O-CH ₂ -CH ₂ ) n -OH wherein n is an integer of _{5 to} 25, and R ₅ is C ₁₁ to C ₁₈ Alkyl); A fatty acid polyoxyethylene glycol (R ₆ -CO- (O-CH ₂ -CH ₂ ) m -OH: m = an integer from 5 to 25, and R ₆ = C ₁₁ -C ₁₈ alkyl); Alkylphenyl polyoxyethylene glycol (R ₇ -Ar-O- (CH ₂ -CH ₂ -O) i H: Ar = benzene ring, i = integer from 5 to 25, R ₇ = C ₁₁ -C ₁₈ alkyl); Polyoxyethylene glycol: mention may be made of at least one selected from _{(H- (O-CH 2 -CH} 2) i-OH i = an integer, and the total molecular weight of 1000 to 30000.).

On the other hand, in order to improve the detergency of the above-mentioned surfactants, the following carbonates (for example, sodium carbonate (Na ₂ CO ₃ ) or sodium hydrogencarbonate (NaHCO ₃ )) and silicates , layered crystalline _{(layered crystalline) α-Na 2} SiO 3 or β-Na ₂ SO _3), phosphates (e.g., orthophosphoric acid, pyrophosphoric acid, tripolyphosphoric phosphoric acid, tetra poly-phosphoric acid or salts thereof), Phosphonates (e.g., diethylenetriaminepentamethylenephosphonate, aminotrimethylenephosphonate, 1-hydroxyethylene-1,1-diphosphone), nitrilotriacetic acid or its salts, ethylenediamine Tetraacetic acid or a salt thereof, and a material auxiliary agent for prevention of re-contamination and an absorber, such as carboxymethylcellulose, polyethylene glycol, polyvinyl alcohol, polyvinylpolydone, polyacrylic acid or its salt, The like can be used a copolymer or a salt or a sulfate of the hotel.

In the case of sodium silicate, which is a component to be introduced into the mixer in the present invention, the viscosity is less than 10 parts by weight because the stickiness of the slurry increases in the mixer. And the ratio of Na ₂ O: SiO ₂ is 1: 1 to 1: 3.

As the surface modifier, it is preferable to use at least one selected from powder zeolite, talc, clay and silica, and it is preferable that at least 50 wt.
