Description

Water-saving phosphorus-free strong washing powder for use in laundries

Technical field

The invention belongs to a kind of concrete washing powder, be specifically related to the special-purpose water-saving without phosphorus powerful washing powder in a kind of laundry.

Background technology

Persistently overheating along with China market economy, the continuous increase of people's income, the level of consumption is also improving constantly, and city size constantly expands, and impels the service organizations such as hotel, hotel, hospital, chain food and drink, large-scale sauna bathing and cosmetology also constantly to develop thereupon.But, in these industry development growths, some associated problems have been exposed, wherein most importantly the development of " cleaning of high-speed high-quality " industry, because if there is not the supporting raising of the cleaning industry of high-speed high-quality, the development of these service industries will be restricted to a great extent.

The people's livelihood service industry such as hotel, hotel is when traveller increases its business scale of constantly expansion, and is more and more higher to the requirement of cleaning performance; The tablecloth, napkin, cook's working suit that simultaneously chain catering trade is used; Towel, bath towel, bathrobe that the towel that the cosmetology chief minister uses, sheet etc. and some large-scale public places of entertainment, hotel use, if do not take the mode of washing of science, the washing composition that does not use some to have specific function will cause a large amount of resources and the waste of the energy.

Investigation according to authoritative department is adjusted, and annual not environmental protection of washing composition because of use, the not science of mode of washing cause number with the waste of hundred million tons water resources and a large amount of articles for washing and manpower to country.So select the washing composition of environment-friendly type, the mode of washing of science is the practical problems that solution is badly in need of in the service industries such as more current large and medium-sized hotels, hotel, food and drink, cosmetology, amusement and recreation mechanism.Wherein primary problem is to select suitable washing composition.2006, the someone applied for the laundry with powerful washing powder patent CN101113389A, and this patent has provided a kind of laundry special-purposed strong stain-removing washing powder, does not consider the water-saving performance of product.

Along with environment protection and green movement are generally paid attention in the whole world; meet the mild, naturalization, enrichment of environmental requirement, easily the nuisanceless green product of degraded, recyclability will become the main flow of from now on articles for washing production and consumption, energy consumption is low, pollute little product will more and more be subject to human consumer's favor.So use novel functional tensio-active agent, accelerate development energy-saving and water-saving type articles for washing, meet the requirement of country's " energy-saving and emission-reduction ", can comply with the trend of domestic society, Economic development, catch up with world's bleeding edge, have positive meaning and wide market.

Aforesaid carboxylate surface active agent has following constitutional features:

R ₁-[OC ₂H ₄] _m-COONa

R in the formula ₁Can be C ₈～C ₂₀Straight chain or with the C of a methyl ₈～C ₂₀Branched paraffin, m are 0～9.

Aforesaid tetrahydroglyoxaline or trimethyl-glycine series Amphoteric phosphated surfactant have following constitutional features:

R in the formula ₁Can be C ₈～C ₂₀Straight chain or with the C of a methyl ₈～C ₂₀Branched paraffin, R ₂Can be C ₂～C ₅Vitriol, sulfonate and carboxylate salt, R ₃Can be C ₈～C ₂₀Straight chain or with the C of a methyl ₈～C ₂₀Branched paraffin or secondary alcohol.

The present invention is with the by weight proportion weighing of all components, mix, aging, oven dry, broken, sieve, stir, chemically examine and be loaded on packing bag after up to standard, namely obtain needed product.

The product of the present invention's preparation has stronger soil removability, and efficient sterilizing, the ability that eliminates the unusual smell have better saving rinse water performance simultaneously, are widely used in many aspects.Be applicable to clean the towel that the towel used with the clothings such as tablecloth, napkin, cook's working suit, cosmetology chief minister in the dining room, sheet etc. and some large-scale public places of entertainment, hotel uses, bath towel, bathrobe etc.

The product of the present invention's preparation has following advantage: (1) Low-temperature cleaning performance is good; (2) water-saving performance is good, can save about 1/3 rinsing water.(3) stronger soil removability, efficient sterilizing, ability eliminates the unusual smell.
