Background technology:
The human washing composition that uses the earliest is soap.Along with succeeding in developing of organic synthesis tensio-active agent, synthetic detergent has progressively entered people's life.A large amount of productions of 20 world's tetrapropylenes fifties have promoted synthetic detergent at global high speed development.
As one of principal item of synthetic detergent, liquid washing agent appeared at for the 20 actual forties, to the nineties in 20th century, because liquid washing agent has had new variation on form, function, structure, became the important kind that is only second to powdery in the washing composition.
Compare with solid detergent, need not dissolving before liquid washing agent uses, have the advantages such as easy to use, that dissolving is rapid, the cold washing performance is good.
Liquid washing agent generally is divided into fabric washing composition, hard surface cleaner and Personal hygiene sanitising agent.Hard surface cleaner is a large class washing composition, comprises dish washing detergent, daily hard surface cleaner, metallic surface sanitising agent and vehicles sanitising agent.
Vehicles sanitising agent is divided into again car sanitising agent, heavy dirty automobile cleaning agent, garage floor sanitising agent, air tube sanitising agent, truck sanitising agent, aircraft sanitising agent, train sanitising agent etc. usually.
Summary of the invention:
For the prior art above shortcomings, technical problem to be solved by this invention provides a kind of heavy dirty automobile cleaning agent.
Technical problem of the present invention is achieved by following technical proposals:
A kind of heavy dirty automobile cleaning agent, raw material by following weight part forms: 80 parts in water, ethoxylated dodecyl alcohol 8-12 part, sodium lauryl sulphate 8-12 part, C8-10 fatty alcohol-polyoxyethylene ether phosphate monoester 2-4 part, potassium silicate 1-3 part, diethylene triamine pentacetic acid (DTPA) iron-sodium complex 0.1-0.3 part, dicarboxyl methylalanine trisodium 0.1-0.3 part.
Ethoxylated dodecyl alcohol, sodium lauryl sulphate, C8-10 fatty alcohol-polyoxyethylene ether phosphate monoester, potassium silicate, diethylene triamine pentacetic acid (DTPA) iron-sodium complex and dicarboxyl methylalanine trisodium are added to the water, be heated to 40-60 ℃, mix, can make this heavy dirty automobile cleaning agent.
Heavy dirty automobile cleaning agent of the present invention has good dirt removal effect, is applicable to the cleaning of common crust, and does not hinder the automobile crust, is particularly suitable for the cleaning of heavy dirty automobile.
Embodiment:
Following embodiment further specifies of the present invention, rather than limits the scope of the invention.In the present invention, if no special instructions, each raw material is all take working substance content as 100%.

Test case
15cm * 15cm ceramic coated steel plate, check weighing W1, apply the dirt of about 25 grams of one deck on the steel plate, in 232 ℃ of lower roastings 1 hour, check weighing W2 evenly sprayed 5 grammes per square metres dirts automobile cleaning agent and to shine on plate, placed 2 hours under the room temperature, then under 60 ℃ of hot water flow, use the sponge rinsing, oven for drying, check weighing W3.By weighting method, draw soil removal efficiency.
Above-mentioned dirt is comprised of 50wt% chicken fat, 20wt% vegetables oil, 20wt% stearic acid, 5wt% tomato-sauce, 5wt% particulate sugar.
Soil removal efficiency=[(W2-W3)/(W2-W1)] * 100%
