Abstract

The invention relates to detergent compositions, in particular to the preparation of an agent for cleaning a hard surface. The goal is to reduce the adhesiveness of the detergent base with an increased content of sodium alkyl benzene sulfonate, to increase the flowability and reduce the dustiness of the product. The preparation of the agent is carried out by preparing the detergent base of the agent (containing sodium alkyl benzene sulfonate), spray drying and then mixing it with an abrasive, alkaline and bleaching components using an additive. The latter ensures flowability and non-traceability of the finished product. Oligomethylsiloxane is used as an additive, which is introduced into the washing base in an amount of 0.2-2.0% of its mass before spray drying, and the washing base is mixed with abrasive, alkaline and bleaching components taking into account the total content of oligomethylsiloxane in the medium 0, 01-0.20% based on the weight of the product. 4 tab.

Description

PMS-1R fluids, 33.0 g of sodium silicate (SiO-30 masD, silicate module 2.5) | 2 h g sodium tripolyphosphate and 12 g soda ash. The dispersion of the polymethylsiloxane liquid in the aqueous suspension is carried out by stirring for 60 seconds with an increase in the rotation speed of the stirrer to 200 rpm. The aqueous suspension at 90 ° C with the polymethylsiloxane liquid dispersed in it with constant stirring is pumped into a spray dryer. In the drying chamber, the aqueous suspension with the dispersed additive PNR-IP is sprayed with a centrifugal spray. Drying is carried out with heated air, the temperature of which at the inlet is 270 ± 5 ° C and at the outlet 107 ± + 3 ° C. The dried base in the cyclone is separated from the air and collected in containers. A detergent ingredient is obtained - a base with a content of oligomethylsiloxane of 2.0%, of composition k (Table 1).

For half 1000 g of the finished detergent, the components are poured into the mixer in the following amounts: SOO g of the detergent base obtained, 6 g of sodium tripolyphosphate, 8 g of soda ash, 100 g of sodium peroxoborate (active oxygen content 9% by weight), 2 g odorants, 78 g of quartz abrasive and mixed for 10 minutes until smooth. Get ready-made tool composition (table. 2), containing 0.2 wt.% Additives, introduced with detergent ingredient.

Example 2: Carried out analogously to example 1, but drying is carried out in the presence of 2, k g of additive. The resulting dry detergent ingredient corresponds to composition 5 (Table 1). The finished product containing 0, the additive, introduced with a washing base, has the composition 5 (Table 2) with indicators at the level of the composition 1 (Table 2).

Example 3: Carried out analogously to example 1, but for preparing 100 g of a dry detergent ingredient - base. with a surfactant content of 60 May., take g of sodium alkylbenzene sulfonate aqueous solution, 1 g of PMS-100 brand polymethylsiloxane liquid and 50 g of sodium silicate. A dry detergent ingredient of composition 13 is obtained (Table I

To obtain 1000 g of the finished product, 70 g of the detergent ingredient obtained, 20 g of soda ash, 30 g of sodium tripolyphosphate, 100 g of sodium peroxoborate, 2 g of odorant, and 77ft g of quartz abrasive are mixed. Get the tool composition 3 (table. 2), containing 0,072 additives.

An example. It is carried out analogously to example 1, but to obtain 100 g of a dry detergent ingredient with a surfactant content of 80% by weight. Take 180 g of an aqueous solution of sodium alkyl benzene sulfonate in which 0.2 g of polymethylsiloxane PMS-200 liquid is dispersed, in the presence of which the washing ingredient is dried . Get dry detergent ingredient of composition 17 (PL. 1}

To obtain 1000 g of the finished product, 50 g of the detergent ingredient obtained, 20 g of soda ash, 30 g of sodium tripolyphosphate, 100 g of sodium peroxoborate, 2 g of odorant and 798 g of quartz abrasive are mixed. Get the tool (composition 2, table. 2), containing 0.01 wt.% Oligomethylsilane.

PRI me R 5. It is carried out analogously to Example k, but the drying of the detergent ingredient is carried out in the presence of 0.1 g of an additive. Get dry detergent ingredient of composition 16 (table. 1). The finished product corresponds to the composition 1 (table. 2). A content of 0.005 May;;, oligomethyl-siloxane PMS-200 in the finished product does not provide a means of improving the physicomechanical parameters.

In tab. 1 presents data on the tensile strength (stickiness) of the dry detergent ingredient - the basis obtained by the proposed method, of different compositions.

From the data given in table. 1, it can be seen that the addition of the additive in the range of 0.2-2.0 wt.% Gives a reduction in the tensile strength of the detergent ingredient with a different content of surfactant to the required level (less than 100 Pa). The washing base obtained by the proposed method, with a surfactant content of 0 wt.%, Has a low tensile strength of from 51 to 80 Pa. (compounds 2, 3 and), when the content of surfactant in the detergent ingredient is 60 wt. W - 51-84 Pa (compositions 12-D), and at 80 May. 2 surfactant - 72-93 Pa (compositions 17-19).

A detergent ingredient with a surfactant content of wt.% Can be obtained from a component water suspension, with a surfactant content of 60 wt.% - from a 2-component suspension, and with

Surfactant 80 masD - from one component - an aqueous solution of sodium alkyl benzene sulfonate. For the preparation of the detergent ingredient, 0 and 5% aqueous solutions of mixtures of sodium salts of alkyl benzene sulfonic acids obtained from normal paraffins and de-flavored kerosene are used.

The introduction of oligomethylsiloxanes in an amount of 0.1 wt.% Does not give the required reduction in tensile strength (compounds 1, 6, 11 and 16), an increase in the additive to 2, May 2; is not advisable because it is not accompanied by further improvement of the properties ( formulations 5. 10, 15 and 20).

In tab. Figure 2 shows the results of experimental studies of a means for cleaning a solid surface obtained by the proposed method.

From the data presented in the table, it can be seen that when the content of oligomethylsiloxane is in an amount of 0.01–0.20 May.% In the finished product, the tensile strength, compactibility, and angle of repose decrease to the required manufacturability ( 2-M. With the introduction of 0.005 May.2 into the agent; oligomethylsiloxane (composition 1), a sufficient reduction in tensile strength and improved flowability is not ensured. Increasing the content of oligomethylsiloxane in the medium to 0.2 masD (composition 5) is impractical, since -chemical indicators with nificant not improved.}

As an additive, various compounds belonging to the class of oligomethylsiloxanes can be used: polymethylsiloxane fluids of linear and branched structure of various grades, as well as low molecular weight dimethylsiloxane rubbers.
