Abstract
The invention relates to a washing additive which is prepared from the following raw materials in percentage by weight: 10-20% of sodium carbonate, 5-15% of sodium hydroxide, 1-15% of citric acid, 0.05-2% of a brightener and 55-70% of sodium silicate. The washing additive provided by the invention has the advantages of no moisture absorption, easiness in dissolution and strong decontaminating effect. The invention further relates to a technological method for producing the washing additive. The method comprises the following steps: dissolving sodium silicate at 160 DEG C into a liquid; filtering; adding the sodium carbonate, the sodium hydroxide, the citric acid and the brightener and carrying out a reaction at 90-110 DEG C; concentrating the reacted mixed liquid into a thick liquid with the solid content being 40-50%; then, heating to raise temperature to 85-95 DEG C in a tank body; and finally carrying out spray drying to obtain powder. The production process provided by the invention can increase the capacity.
Description
Technical field
The present invention relates to a kind of additive of washing composition, and the method for producing this additive.
Technical background
The China day by day deepening at environmental protection concept, the usage quantity of environmentfriendly products is also increasing year by year.At present, in the environment friendly washing product that China produces---as washing powder, liquid detergent etc., mostly be and added the additive that contains lamina sodium silicate.But the easy moisture absorption of examples of such additives, solvability are bad, after adding in articles for washing, the clean effect of articles for washing is also general.
Summary of the invention
The object of the invention is to provide a kind of environment friendly washing additive of nonhygroscopic, soluble and strong detergency.Another object is to provide its production method.
For reaching above-mentioned first object, provide following technical scheme:
A detergent additive, comprises the raw material of following weight percent: sodium carbonate (Na
2cO
3) 10～20%, sodium hydroxide (NaOH) 5～15%, citric acid 1～15%, whitening agent 0.05～2%, water glass 55～70%.
As preferred scheme, described water glass is lamina sodium silicate.
Compared with prior art, adopt technical solution of the present invention, changed the component prescription of existing detergent additive.Make the additive trend of original meta-alkalescence neutral, no longer the moisture absorption; Improved solvability simultaneously, made it be easy to dissolve, and strengthened clean effect.
The present invention is for being added on articles for washing, increases the soil removability of articles for washing.When producing articles for washing---as washing powder etc., according to the characteristic of articles for washing, according to certain proportioning (articles for washing weight percent 10～20%), add the present invention, after mixing, can use.
On the other hand, for reaching above-mentioned second object, solve by following technical solution: a kind of method of producing above-mentioned detergent additive.This method comprises the steps: described water glass in 160 ℃ of meltings; Described sodium silicate liquid after melting is filtered; In described sodium silicate liquid after filtration, add described sodium carbonate, described sodium hydroxide, described citric acid and described whitening agent, react, it is 90～110 ℃ that temperature of reaction is set; It is 40～50% liquid that reacted mixing liquid is concentrated into solid content; Mixing liquid after concentrated is heated to 85～95 ℃; Spray dry, become powder.
As preferred scheme, in the processing method of the above-mentioned detergent additive of production of the present invention, concentrated mixing liquid is the mode that adopts heating concentrated.
Compared with prior art, the method for production detergent additive of the present invention, has improved production capacity.After reaction kettle for reaction, mixing liquid has been carried out to concentration, making it become solid content is 40～50% thick liquid.Spray-dired production capacity after concentration has improved, and don't can be in drying process, is bonded at and on appts wall, produces coking.
