Abstract

The invention relates to a cleaning agent for windshield glass, which is characterized by being prepared by mixing the following raw materials in parts by weight: 0.1-1.0 part of alkyl polyglucoside (C8-C10), 0.01-0.6 part of monoester sodium salt of lauryl alcohol polyoxyethylene phthalic acid, 1.0-5.0 parts of propylene glycol monomethyl ether, 0.01-0.3 part of polyvinylpyrrolidone K-15, 0.01-0.1 part of 2-phosphono butane-1,2,4-tricarboxylic acid, 1.0-5.0 parts of 1,3-propylene glycol, 10.0-60.0 parts of ethanol and 40.0-90.0 parts of deionized water. The product has good cleaning and decontaminating performances and vehicle erosion preventing advantage and effect.

Description

Cleaning agent for windshield glass

Technical field

The present invention relates to a kind of cleaning agent for windshield glass, be applicable to the cleaning cleaning of windshield, belong to detergent applications.

Background technology

Windshield belongs to the one of crust, it is except the chemical to automobile throughout the year, to Climate and Environment Variation, there is very strong adaptability, the white performance that removes the snow fast should be had in winter, windshield often can adhere to dirt simultaneously, the moiety complexity very of dirt, comprising dust, spot, water wave, natural gum, shellac, lubricating oil, lubricating grease, petrol and diesel oil, sweat mark, remaining polishing wax etc., this just requires that various different types of dirt just must thoroughly be driven away by cleaning agent for windshield glass in a cleaning process, and cut can not be left on glass, hot spot and striped etc. affect the vestige of driver's seat, the cleaning agent for windshield glass of current use pays attention to cleaning performance, and the automobile metal car-body corrosion ignored because clean-out system causes, how under the prerequisite ensureing cleaning performance, not corrode car body, also do not report both at home and abroad at present.

Summary of the invention

Object of the present invention provides a kind of and has good cleaning performance in order to solve above-mentioned prior art Problems existing and do not corrode the low residue cleaning agent for windshield glass of vehicle body just, thus makes the visual field of officer not interrupted, ensures safe driving.

The object of the invention is to be realized by following technical proposal:

Cleaning agent for windshield glass, it is by the raw material of following weight proportioning through mixing together,

Alkyl glycoside (C8-C10) 0.1 ~ 1.0 part

Ethoxylated dodecyl alcohol phthalic monoester sodium salt 0.01 ~ 0.6 part

Propylene glycol monomethyl ether 1.0 ~ 5.0 parts

Polyvinylpyrrolidone K-15 0.01 ~ 0.3 part

2-phosphinylidyne butane-1,2,4-tricarboxylic acid 0.01 ~ 0.1 part

1,3-PD 1.0 ~ 5.0 parts

Ethanol 10.0 ~ 60.0 parts

Deionized water 40.0 ~ 90.0 parts.

Raw material of the present invention with ethanol and deionized water for major ingredient and kinds of surface promoting agent, auxiliary agent are composited, wherein alkyl glycoside (C8-C10) has excellent surfactivity, strong detergency and without cloud point, gel-free phenomenon, compatibility is splendid, there is good synergistic effect, pungency is not had to skin, nontoxic, fully biodegradable, environmentally safe, especially has certain corrosion inhibition with ethoxylated dodecyl alcohol phthalic monoester sodium salt (commodity are called PAES) compound to various metal, has splendid soil removability, propylene glycol monomethyl ether, molecular formula C ₄h ₁₀o ₂, be dispersion agent, clean-out system, polyvinylpyrrolidone K-15, code name is PVP, is buider, has and well increases clean, filming function, especially have inhibition to aluminium flake, and can not have an impact to paint film, 2-phosphinylidyne butane-1, 2, 4-tricarboxylic acid, it has the structural performance of phosphonic acids and carboxylic acid group, and have good corrosion and scale inhibition performance, code name is PBTCA, it is Scale inhibitors, the solvent that product of the present invention is selected is 1, 3 propylene glycol, protective membrane is formed on vehicle glass surface, have and press down bubble effect, keep glass transparent degree, winter is for reducing the freezing point of product, the ice of solubilized vehicle glass surfaces externally and internally, frost, high molecular alcohol kind solvent, cleaning solvency power is strong, good film-forming property, the lubricating oil that its solubilized polarity is stronger, lubricating grease, the macromole lipid such as petrol and diesel oil, especially good to galvanized steel sheet corrosion inhibition, and can not have an impact to paint film.

In order to observe the effect of this product, detersive power, metallic corrosion and the impact on lacquer painting are tested, detersive power presses CAS144 standard, metallic corrosion condition presses JASO M324-1979 standard: 50 DEG C ± 2 DEG C, 48h ± 1h, press CAYBS-18-1992 standard to the impact of lacquer painting, test-results is in table 1

Table 1 test-results

Said composition is by optimizing additive as can be seen from Table 1, and in guarantee detersive power 98% situation, its metallic corrosion is extremely low, and on vehicle body lacquer painting without impact, enamelled coating without on expansion, lacquer painting without naked eyes visible residue

Due to take technique scheme make the technology of the present invention compared with the prior art this product there is advantage and the effect of good clean dirt performance and good anti-vehicle body corrosive nature.
