Abstract
The invention provides a caution liquid, comprising phenolphthalein, sodium hydroxide, fluorescein and water. The phenolphtalein is a leuco dye which reacts with sodium hydroxide to generate a sanguineous solution. The caution liquid has an eye-catching color and can emit strong yellow fluorescence by visible light illumination, and can have a good caution effect visually. Meanwhile, the caution liquid can automatically disappear without any treatment or be disappeared rapidly by water flushing. The caution liquid can also be prepared into a spraying agent, which is convenient for automobile and emergent treatment when an accident occurs. The chemicals used in the invention are cheap, easily available, at low costs and apt to production.
Description
Technical field
The present invention relates to warn liquid, specifically belong to a kind of caution liquid that can be used for multiple occasion mark caution such as the scene of a traffic accident, working-yard and dangerous scene.
Background technology
When now provisional alert flag is done at the scene of a traffic accident, working-yard and dangerous scene etc., adopt the chalk line sometimes, the chalk line is not only used inconvenient, and color is eye-catching inadequately, and is difficult for evening being discovered.When removing caution, chalk line vestige can not disappear automatically.
Summary of the invention
The objective of the invention is at above-mentioned these shortcomings, provide a kind of color caution liquid eye-catching, that under visible light shines, can send the intensive yellow fluorescence and can disappear automatically.
A kind of caution liquid provided by the invention, its feed composition is by weight percentage:
Preparation process is as follows: take by weighing phenolphthalein, sodium hydroxide and fluorescent yellow according to the above ratio, add then in the entry, stirring and dissolving promptly obtains blood red caution liquid.
Can prepare the special use caution liquid of different concns according to the length of duration of service.Phenolphthalein concentration is long more high more duration of service in the caution liquid.
Compared with prior art, the caution liquid color of the present invention's preparation is eye-catching, can send the intensive yellow fluorescence under visible light shines, and visually the people is played good warning function; Simultaneously, this caution liquid need not handled and can disappear automatically or water flushing allows its quick disappearance.This caution liquid can be made into sprays, is convenient to carry on each car, can be used for emergent management when traffic accident occurring.
