ABSTRACT:
The present invention discloses aqueous LCD cleaning agent compounds and their fabrication methods. Said cleaning agent compounds comprise of double fatty acid polyethylene glycol ester, fatty alcohol polyoxyethylene ether, polyethylene(3) glycol alkyl ether tri(alkyl ethers)amine sulfate and/or polyethylene(3) glycol enyl ether tri(alkyl ethers)amine sulfate, alkyl benzenesulfonic acid, lecithins and water. In particular, the weight of the ingredients in the compounds as a weight percentage of the weight of the compounds is: double fatty acid polyethylene glycol ester (10-50 wt %), fatty alcohol polyoxyethylene ether (5-60 wt %), polyethylene(3) glycol alkyl ether tri(alkyl ethers)amine sulfate and/or polyethylene(3) glycol enyl ether tri(alkyl ethers)amine sulfate (5-20 wt %), alkyl benzenesulfonic acid (1-15 wt %), lecithins (1-10 wt %), water (5-50 wt %). Embodiments of the aqueous LCD cleaning agent compounds of the present invention can effectively remove both the crystal liquid materials in the gaps between the two glass substrates and foreign contaminate particles attached on the surfaces of the glass substrates. Moreover, the LCD cleaning agent compounds have the characteristics of low toxicity, environmental friendliness, low flammability and high cleaning capabilities for various crystal liquid materials.
