Problems solved by technology

[0003] In fire rescue work, crowd evacuation is the focus and difficulty of firefighting work; usually, the safety signs and fire signs used in escape routes in ordinary public places and underground confined spaces mainly rely on electric light source instructions; when a fire occurs, due to the power supply If it is accidentally cut off, in a dark room environment with dense smoke, these fire signs that rely on power to emit light will lose their indicating function, resulting in the trapped people being unable to identify the evacuation direction in time and reducing the escape efficiency of the people

Abstract

The invention discloses a preparation method of colored fluorescent diatom ooze which is prepared from the following raw materials in parts by mass: 10-50 parts of diatomite, 5-10 parts of high-viscosity attapulgite, 6-10 parts of kaolin, 8-12 parts of light calcium carbonate, 10-20 parts of rutile titanium dioxide, 9-16 parts of organic silicon modified acrylic resin, 5-25 parts of polyvinyl alcohol, 3-5 parts of hydroxypropyl methyl cellulose, 2-10 parts of white cement, 2-5 parts of a titanate coupling agent and 10-70 parts of luminescent materials with various colors; and by utilizing a powder airflow method, various powder raw materials are uniformly mixed in a gas state in a closed space in a powder airflow manner, then are subjected to ball milling and ultrasonic crushing, pass through a 200-mesh sieve, and are collected and stored.

Description

Technical field: [0001] The invention relates to the technical field of wall decoration materials, in particular to a colored fluorescent diatom mud and a preparation method thereof. Background technique: [0002] Diatomaceous earth is amorphous SiO 2 A biogenic siliceous porous sedimentary rock of predominant chemical composition. With diatomite as the main functional filler and inorganic gelling material as the main binder, the dry powder wall coating material for decoration and decoration prepared through the mixing process is called diatom mud. Diatom mud does not contain any heavy metal ions, radiation substances and other toxic and harmful ingredients, and is a green and environmentally friendly wall decoration material. [0003] In fire rescue work, crowd evacuation is the focus and difficulty of firefighting work; usually, the safety signs and fire signs used in escape routes in ordinary public places and underground confined spaces mainly rely on electric light so...
