AI Technical Summary

Technical Problem

Existing high-speed train windshield cleaners are ineffective at removing complex dirt, especially protein from dead mosquitoes and insect glue, from the windshields of high-speed trains. They also take a long time to clean, affecting the driver's visibility and increasing cleaning and maintenance costs.

Method used

A glass cleaning agent for high-speed trains was prepared by using a formulation of polyoxyethylene cocoate, sodium dodecyl sulfonate, dodecyl glucoside, chelating agent, brightener, corrosion and scale inhibitor, cleaning aid, and fragrance. The agent utilizes the solubility of surfactants and the chelating ability of chelating agents, combined with the defoaming properties of brighteners, to achieve rapid cleaning.

Benefits of technology

It enables rapid dissolution and removal of dirt on train windows, is safe and non-corrosive, adapts to temperature changes in different regions, is environmentally friendly, cost-effective, and suitable for use on high-speed trains.

Abstract

The application discloses a high-speed train glass cleaning agent and a preparation method thereof. The high-speed train glass cleaning agent is composed of the following components in parts by weight: a mixture of polyoxyethylene coconut fatty acid ester, sodium dodecyl sulfonate and dodecyl glucoside in a molar ratio of (1-2):(1-3):(1-4) 10-30 parts, a chelating agent 10-15 parts, a brightener 15-25 parts, a corrosion and scale inhibitor 10-20 parts, a builder 20-30 parts, a fragrance 0.5-1.5 parts, and water 30-40 parts; the builder is a mixture of isopropyl alcohol, ethylene glycol and ethylene glycol monobutyl ether in a molar ratio of (1-2):(1-2):(1-3). The glass cleaning agent has good dissolving and eliminating capacity for common dirt, rust, and especially oil stains, protein, insect glue and other pollutants caused by insect collision on a high-speed train; the components are mild, do not cause corrosion to the contacted glass, metal and rubber, and do not damage paint coating, composite materials and the like.
