Embodiment 1

[0044] This embodiment provides a glass cleaner for automobiles, the parts by weight of the raw materials of the cleaner are as shown in Table 1 #1.

[0045] The preparation method of described automobile glass cleaner is:

[0046] A) Pre-dissolve the anionic surfactant in water into a certain proportion of the solution according to the weight fraction ratio described in Table 1-1#, and the amount of the water is 5-15% of the total water;

[0047] B) Add water accounting for 40-60% of the total water in the chemical tank, add the anionic surfactant solution pre-dissolved in step (A), non-ionic surfactant and additives in turn while stirring, and stir to dissolve completely;

[0048] C) Then add solvent, preservative and corrosion inhibitor in sequence, stir well and then add pH adjuster to adjust pH to 6.5-10;

[0049] D) Finally, add the pigment, make up the remaining water, stir, and filter to obtain the antifreeze type automobile glass cleaner.

[0050] The freezing point...

Embodiment 2

[0059] This embodiment provides another glass cleaner for automobiles, the parts by weight of the raw materials of the cleaner are as shown in Table 1 #2. Refer to Example 1 for the preparation method of the glass cleaner.

[0060] The freezing point of the automotive glass cleaner is -42°C, and the flash point is 65°C.

[0061]Detect the detergency and corrosivity of described automobile glass cleaner respectively:

[0062] (1) Detergency: The glass cleaner was tested according to the standard GB / T 23436. After the test, if figure 2 As shown, it has a good decontamination effect on the stains on the car glass without residue.

[0063] (2) Corrosion: According to the GB / T 23436 standard, the corrosion test was carried out on aluminum sheets, copper sheets, and galvanized steel sheets using the glass cleaner. According to the test results, the glass cleaner is non-corrosive to the three materials.

Embodiment 3

[0065] This embodiment provides another glass cleaner for automobiles, the parts by weight of the raw materials of the cleaner are as shown in Table 1 #3. Refer to Example 1 for the preparation method of the glass cleaner.

[0066] The freezing point of the automotive glass cleaner is -43°C, and the flash point is 66°C.

[0067] Detect the detergency and corrosivity of described automobile glass cleaner respectively:

[0068] (1) Detergency: The glass cleaner was tested according to the standard GB / T 23436. After the test, if image 3 As shown, it has a good decontamination effect on the stains on the car glass without residue.

[0069] (2) Corrosion: According to the GB / T 23436 standard, the corrosion test was carried out on aluminum sheets, copper sheets, and galvanized steel sheets using the glass cleaner. According to the test results, the glass cleaner is non-corrosive to the three materials.

Abstract

The invention provides a glass cleaner for automobiles and a preparation method thereof. The raw materials of the glass cleaner include solvents, anionic surfactants, nonionic surfactants, spices, additives, preservatives, corrosion inhibitors, dyes , a pH adjuster and water. Existing car glass cleaners use a large amount of flammable liquids as solvents, which have a low flash point and are easy to volatilize. Such glass cleaners can easily cause fires during production, storage, transportation and use. or an explosion accident. In order to solve this problem, the present invention uses high-flash point, low-residue raw materials for compounding. On the premise that the flash point of the product is higher than 61°C and the freezing point is lower than ‑8°C, it can effectively clean the glass without corrosion and low residue. Leaves no trace.

Description

technical field [0001] The invention belongs to the field of hard surface cleaning, in particular to a glass cleaner for automobiles and a preparation method thereof. Background technique [0002] Fires or explosions caused by dangerous goods occur from time to time, seriously endangering the lives and property safety of consumers. The flash point refers to the lowest temperature at which the vapor escaping when heating the sample in the flash point cup can flash instantly in the presence of a flame. The flash point is an important parameter to measure the fire risk of flammable liquids. The lower the flash point, the greater the risk; generally, the transportation of goods below 61°C requires a dangerous goods transportation permit. A large amount of flammable liquids are used as solvents in the existing glass cleaners for vehicles. They have low flash points and are easy to volatilize. During the production, storage, transportation and use of glass cleaners for vehicles, ...
