Description

Water-saving environment protection detergent

Technical field

The invention belongs to detergent applications, particularly water-saving environment protection detergent.

Background technology

Because the waste water majority behind the detergent use all enters rivers, Hu Hai by water drain, it is more direct to the influence that water body produces eutrophication.Twentieth century is after the middle and later periods, and China entrance of Changjiang River, the nitrogenous phosphorus content of Zhujiang River water quality increase, landlocked Taihu Lake, the West Lake, East Lake, Dian Chi and Chaohu etc., and the urban drinking water waterhead area also causes the excessive breeding of algae because of nutritions such as phosphorous nitrogen exceed standard.Water body is smelly, and drinking water quality is reduced, and has influenced human health.Therefore, washing composition limit phosphorus is advocated in the whole nation does not have the phosphatization process under the unified management of relevant functional departments of government, has accelerated to implement the production of the without phosphorus low-phosphorous cleaning product of development, in case lake addition polymerization eutrophication, the conservation of nature ecosystem, protection environment for human survival.

We can see in [relation of tensio-active agent decontamination ratio in the washing powder] table 1 that provides according to calendar year 2001 light industry " household chemicals science " magazine the 24th volume the 6th phase " focus search ", the all uses of phosphorus restriction in washing composition of most of country such as Japan, Europe, America at present, the domestic present use of phosphorus restriction that under the major premise of carrying out sustainable development energetically, also begins.

Tensio-active agent and decontamination ratio relation in table 1 washing composition:

Kind	Quantity/number		Surfactant content/%				Decontamination ratio
											Scope		On average		Scope		On average
			Time	1998	2000	1998	2000	1998	2000	1998									2000	1998	2000
Phosphorous	68	40									11-23	10-24	15.98	16.60	0.9-2	1.1-2.5	1.40	1.52
			Without phosphorus	60	12	6-29	8-23	16.25	17.50	0.7-1.6									1.1-1.6	1.17	1.27

As everyone knows, water is Source of life, is human reaching to one of biological primary condition of depending on for existence.The water globe resource is constantly destroyed, and it is the major hidden danger that jeopardizes the human life that water resources is seriously burst general.The protection water resources is administered contaminated water source, water saving, and conserving natural habitats is one of our human problem demanding prompt solution.

Summary of the invention

The objective of the invention is to overcome existing phosphorous and low-phosphorous cleaning product environment caused the defective of severe contamination, provide a kind of safe, that the raw material environmental protection is easy to get, also can improve the without phosphorus water-saving environment protection detergent of washability.

Tensio-active agent among the present invention is selected the biological degradability height for use and is better than the product of international required standard.The reasonable combination of α one rare basic sulfonate and senior starch adds C again in the tensio-active agent ₁₂～C ₁₄The collaborative compatibility of aliphatic alcohol polyoxyethylene more improves wetting, emulsification, degreasing and the soil removability of tensio-active agent when improving biological degradability.Including the washing assistant ethylenediamine tetraacetic acid (EDTA) is important organic sequestering agent, toxinicide for heavy metal, the adding of washing assistant and Trisodium Citrate is peace and quiet as water after this washing composition is dissolved in water, can reduce the pollution of washing composition in water and the toxicity of various washing composition, this product is the very high product of safety coefficient.Water glass in the auxiliary agent is a kind of good dispersion agent, tool demineralized water and antiseptic property.Xylo-Mucine is the white fiber shape, has well to prevent the soil redeposition effect.

It is extensive that the present invention adopts raw material easily to fetch the source, and technological design is rationally advanced.For out and out pollution-free.The health environment-friendly product that washability is economized on water by force, economized on electricity.

Water-saving environment protection detergent component of the present invention and content are:

Yellow soda ash 15～40wt%;

Water glass 10～20wt%;

Anhydrous sodium sulphate 5～30wt%;

C ₁₂～C ₁₄Aliphatic alcohol polyoxyethylene 5～10wt%;

α-rare basic sodium sulfonate 2～15wt%;

Trisodium Citrate 1～15wt%;

Ethylenediamine tetraacetic acid (EDTA) 0.6～5wt%;

Starch 5～10wt%;

Xylo-Mucine 1～2wt%.

The present invention can further add sodium bicarbonate in above-mentioned component, its add-on is 5～10wt% of environment-friendly water-saving clean-out system total amount, to strengthen the anti-hard water of without phosphorus water-saving environment protection detergent.The present invention be a kind of be raw material with the safety and environmental protection composition, no containing metal aluminium 4A zeolite, no zymin, the environment-friendly cleaning agent of no white dyes.The advantage of its synergistic effect can be removed the dirt that the indelible heavy oil spot of common washing composition, bloodstain, milk stain, fruit juice, dish sweat etc. are difficult to remove, and its detergency ability is more than 2 times of common washing composition, is green multifunctional detergent.

The preparation method of water-saving environment protection detergent of the present invention is: earlier the yellow soda ash of 15～40wt%, the water glass of 10～20wt%, the anhydrous sodium sulphate of 5～30wt%, the Trisodium Citrate of 1～15wt%, the ethylenediamine tetraacetic acid (EDTA) of 0.6～5wt%, the starch of 5～10wt% and the Xylo-Mucine of 1～2wt% fully is being mixed in efficient premixed device, and then with the C of 5～10wt% ₁₂～C ₁₄The α of aliphatic alcohol polyoxyethylene and 2～15wt%-rare basic sodium sulfonate liquid starting material once evenly is sprayed in the above-mentioned solid composition that is mixed with high-pressure pump, obtains water-saving environment protection detergent after continuing to mix.

Further add the sodium bicarbonate of water-saving environment protection detergent total amount 5～10wt%, mix, obtain the without phosphorus water-saving environment protection detergent of anti-hard water raising.

Water-saving environment protection detergent of the present invention with the characteristics that the cleaning product that the domestic market occurs is compared is:

1. dangerous raw materials such as without phosphorus, no aluminium, no zymin, no white dyes.

2. water saving, economize on electricity are 60%～70% of common washing composition, and foam is abundant when washing, lather collapse during rinsing.

3. the above-mentioned spot that is difficult to clean had stronger removal ability.

4. selected surfactant biodegradation height can play the special role of administering and protecting the water source.

5. chemical fertilizer remaining in the plant or agricultural chemicals there are very strong emulsification and capacity of decomposition, biological degradability 99.5%.
