Description

A kind of automobile windscreen cleaning agent

Technical field

The present invention relates to the clean-out system technology, specifically a kind of automobile windscreen cleaning agent of nontoxic pollution-free.

Background technology

Automobile is equipped with wiper, but injection water based cleaning agent in the driving process cleans the dirt on the windshield glass.Dirt on the windshield comprises dust, spot, water wave, natural gum, shellac, birds droppings, lubricating oil, petrol and diesel oil, remaining polishing wax etc.Frost is arranged winter, fog is arranged summer, directly influence officer's the visual field, cause very big potential safety hazard.But, when removing dirt, deicing is antifog effectively also to require automobile windscreen cleaning agent, so alcohol that interpolation and water dissolve each other in the clean-out system, to reduce freezing point, more representational is to add methyl alcohol, and methyl alcohol is the main added ingredients of conventional clean agent, and the clean-out system that also has can add lubricated composition.

Yet irritating compositions such as methyl alcohol that contains in the automobile windscreen cleaning agent or ammoniacal liquor, human consumer and environment are caused certain detrimentally affect, if methanol concentration is too high, under the unwitting situation of human consumer, eyes are had to a certain degree injury, so automobile windscreen cleaning agent can only be by explanation requirements in the driving outdoor application.And only add alcoholic content, and glass and wiper there are not lubrication, life-time service can reduce the work-ing life of wiper and glass.

Summary of the invention

Purpose of the present invention just provides a kind of automobile windscreen cleaning agent, and it is better that this clean-out system has cleaning effect, nontoxic, environmental protection, can delay characteristics such as the aging and protection windshield of wiper blade rubbers.

The present invention is achieved by the following technical solutions:

The component and the content of this automobile windscreen cleaning agent are as follows: the ethanol of 10～30 weight %, and the tensio-active agent of 0.01～1 weight %, the dyestuff of 0～0.005 weight %, surplus is a water.

Tensio-active agent is by one or both composite the forming in nonionogenic tenside or the anion surfactant, and the compound proportion of nonionogenic tenside and anion surfactant is 1: 0.1～1: 1;

Nonionogenic tenside is the alkyl alcohol Soxylat A 25-7;

Anion surfactant is alkyl succinic acid sulfonated ester, polyoxyethylenated alcohol sodium sulfate, sodium lauryl sulphate.

In this automobile windscreen cleaning agent or add sequestrant, the inhibiter that is no more than 5 weight % be no more than 5 weight %, one or more the mixing in the antifreeze membrane-forming agent that is no more than 10 weight %, use as mixing, it adds total amount is 0～15 weight %.

Part by weight between sequestrant, inhibiter, the antifreeze membrane-forming agent is 1: 0.1: 0.1～1: 10: 10;

Sequestrant is a disodium EDTA;

Inhibiter is one or both in Starso, Sodium Nitrite, borax, trolamine, benzotriazole, the succinate etc., with 1: 0.1～1 mixed;

Antifreeze membrane-forming agent is a polyalcohols, and ethylene glycol, 1 is arranged, the 2-propylene glycol, and 1, ammediol, 1, the 2-butyleneglycol, 1,3 butylene glycol, 1, the 4-butyleneglycol, one or both mixing in the glycerol, blending ratio is 1: 0.1～1.

Dyestuff is a direct fast blue.

Above-mentioned automobile windscreen cleaning agent adopts preparation method, adds one by one under the normal temperature to be stirred to homogeneous transparent and to get final product.

Add tensio-active agent among the present invention, greatly reduce the tension force of each phase interface.In use anion surfactant or the nonionogenic tenside one or more are composite, improved the cleaning and the emulsifying effectiveness of clean-out system, are a kind of low foaming clean-out systems.

Ethanol that adds in the clean-out system and tensio-active agent and polyvalent alcohol have good composite effect, and nontoxic pollution-free.

Sequestrant can with some metal ion such as Ca ²⁺, Mg ²⁺Deng formation stable chelated body, thereby make washing composition have the function of anti-hard water, during specific to windshield, can reach the cleaning purpose, prevent that dirt from precipitating once more.

The adding of Starso or trolamine etc. in the clean-out system can also be played shock absorption, makes the pH value of clean-out system keep stable (its pH6～9), increases the emulsifying capacity and the emulsifying stability of clean-out system simultaneously, prevents that dirt from precipitating once more.

The pH value of clean-out system can be adjusted arbitrarily by buffer reagent.
