Abstract

The present invention relates to environment protective efficient washing paste. The present invention is prepared from two kinds of surface active agents, and adopts 4A zeolite as assistant washing agents. The present invention has the following specific prescription of 0 to 15 wt% of sodium dodecyl benzene sulfonate, 0 to 15 wt% of sodium dodecyl sulfate, 10 to 20 wt% of 4A zeolite, 5 to 10 wt% of sodium silicate, 1 to 10 wt% of sodium chloride, 0 to 10 wt% of additives, and 20 to 50 wt% of water. Because the present invention prefers two kinds of surface active agents, the washing effect and the hard water resistant capability are greatly improved. Because the present invention selects the 4A zeolite as main assistant washing agents, the present invention has no phosphorus, protects environment, keeps high detergency, and has stable performance simultaneously. The present invention is not stratified at the temperature more than 40 DEGC, and is not crystallized at the temperature less than 5 DEGC. All raw materials in the prescription of the present invention are easy to obtain. The present invention has the advantages of simple production, low cost, easy dissolution, proper alkalinity and broad market foreground, and can wash ramie cotton fabrics and chemical fabrics.

Description

A kind of stable without phosphorus washing cream

Technical field

The present invention relates to a kind of washing cream, especially a kind of without phosphorus, lotion stable performance and economic washing cream.

Background technology

Washing powder, washing cream kind are a lot, and non-phosphide detergent is also many, but stable without phosphorus washing cream does not have.Because as the without phosphorus washing cream of producing has layering, crystallization, flowability to can not form problems such as paste too greatly.

Washing cream is that than the advantage of washing powder washing cream can reduce sodium sulfate in the washing powder prescription, accounts for 50% of washing powder weight, and every kilogram of washing composition will be saved about 0.20 yuan.Remove 14% sodium polyphosphate in the prescription, save again about 0.50 yuan.Every kilogram of washing composition reduces cost about 0.70 yuan, another advantage of washing cream is that dissolution rate is fast when washing clothes, washing effect is given full play to, be dispersed in the aqueous auxiliary agent because tensio-active agent, washing assistant, whitening agent, anti-recontaminate agent and other additives (as carboxymethyl cellulose, white dyes, urea, proteolytic enzyme, essence) expand already, it is faster to dissolve rate of dispersion than solid laundry powder in water.

General washing composition is made up of tensio-active agent (main lotion) and washing assistant and essence pigment etc.Because tensio-active agent costs an arm and a leg, and in order to allow it play one's part to the full, adds washing assistant in the prescription.Main lotion is mainly used anion surfactant such as Sodium dodecylbenzene sulfonate and sodium lauryl sulphate, their meetings and Ca ²⁺, Mg ²⁺Have an effect and lost efficacy.For protect anion surfactant not with water in Ca ²⁺, Mg ²⁺Have an effect, washing assistant is and Ca ²⁺, Mg ²⁺Complex reaction or adsorbing material take place, as tripoly phosphate sodium STPP, EDTA, nitrilo etc.They are energy and Ca ²⁺, Mg ²⁺Complex reaction takes place, and eliminates Ca ²⁺, Mg ²⁺Effect to Sodium dodecylbenzene sulfonate and sodium lauryl sulphate.But tripoly phosphate sodium STPP produces eutrophication to environment, and country bans use of, and the price of EDTA, nitrilo is too expensive.Do not have the washing cream of washing assistant tripoly phosphate sodium STPP to be difficult for producing simultaneously, main difficulty is that product can not become stable paste, is placing the thinning layering of meeting more than 40 ℃, can crystallization in placement below 5 ℃.

Chinese invention patent " is produced the novel method of washing cream ", and (88107337.7) middle washing assistant adopts light calcium carbonate CaCO ₃, lime carbonate exists following precipitation and dissolution equilibrium:

K _sp＝3.8×10 ^-9

Solubleness is:

$S=\left[{\mathrm{Ca}}^{2+}\right]=\sqrt{k_{\mathrm{sp}}}=6.16\×{10}^{-5}\mathrm{mol}\·{\mathrm{dm}}^{-3}$

Be equivalent to dissolve lime carbonate 6.16 * 10 ^-3Gram dm ^-3, with water be 6.16 ‰ by mass percentage, and the anion surfactant usage quantity is about 1 ‰ of a water.At this moment Ca ²⁺With the ratio of anion surfactant be 6: 1, this obviously seriously influences the cleaning function of tensio-active agent.

Summary of the invention

The object of the present invention is to provide a kind of stable without phosphorus washing cream, it is without phosphorus, stable performance, soil removability are strong, produces simple, with low cost simultaneously.

A kind of stable without phosphorus washing cream adopts two kinds of surfactant compounds, and washing assistant adopts 4A zeolite (porous mass) to replace tripoly phosphate sodium STPP, the Ca in its energy planar water ²⁺, Mg ²⁺, play the good effect of washing that helps, and keep the stability of washing cream, have stronger detersive power.The present invention fills a prescription as follows:

Sodium dodecylbenzene sulfonate 0～15%

Sodium lauryl sulphate 0～15%

4A zeolite 10～20%

Water glass 5～10%

Sodium-chlor 1～10%

Additive 0～10%

Water 20～50%

More than each component be mass percent.

The concrete production process of washing cream of the present invention is as follows:

(1) with sodium lauryl sulphate, 4A zeolite, white dyes, urea, carboxymethyl cellulose raw material pulverizing mixing;

(2) under agitation slowly with the water of 100 ℃ of Sodium dodecylbenzene sulfonate addings, slowly add water glass again;

(3) will go on foot mixture in poly-(1) slowly puts in the liquid form mixt in the step poly-(2) and stirred 30 minutes;

(4) sodium-chlor, proteolytic enzyme and essence are put in the mixture of step poly-(3);

(5) cooling, the paste filling machine pack.

Compared with prior art, the invention has the beneficial effects as follows:

(1) removed environmentally harmful washing assistant tripoly phosphate sodium STPP and to main lotion Sodium dodecylbenzene sulfonate and the deleterious washing assistant light calcium carbonate of sodium lauryl sulphate CaCO ₃, select for use the 4A zeolite as main washing assistant, both without phosphorus, keep stronger soil removability again;

(2) prescription of the present invention can be produced a kind of economy, without phosphorus, stable washing cream, and is not stratified through being placed on more than 40 ℃, in non-crystallizable below 5 ℃ (national standard requirement);

(3) the preferred two kinds of surfactant compounds of the present invention, washing clean effect and resistance to hard water greatly improve;

(4) the various raw materials of the present invention's prescription are easy to get, and produce simply, and cost is lower, very easily dissolving, and basicity is moderate, can wash linen-cotton and chemical fibre textile.
