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 mud, which consists of 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, and 8 parts of light calcium ‑12 parts, 10‑20 parts of rutile titanium dioxide, 9‑16 parts of silicone modified acrylic resin, 5‑25 parts of polyvinyl alcohol, 3‑5 parts of hydroxypropyl methylcellulose, 2‑10 parts of white cement , 2-5 parts of titanate coupling agent, 10-70 parts of luminescent materials of various colors; using the method of powder air flow, various powder raw materials can be evenly mixed in a closed space in a "gas state" in the form of powder air flow Then pass through a 200-mesh sieve after ball milling and ultrasonic crushing, and collect and store.

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 It is a biogenic siliceous porous sedimentary rock with the main chemical composition. With diatomite as the main functional filler and inorganic cementitious material as the main binder, the dry powder decorative wall coating material prepared by the mixing process is called diatom mud. Diatom mud does not contain any heavy metal ions, radioactive substances and other toxic and harmful components, and is a green and environmentally friendly wall decoration material. [0003] In the fire rescue work, crowd evacuation is the focus and difficulty of fire protection work; usually, the safety signs and fire signs used in the escape routes of ordinary public places and underground confined spaces mainly rely on electric light sour...
