The application discloses a high-viscosity anti-permeation special caulking paste for bolt holes and a preparation method thereof, and belongs to the technical field of building materials. The caulking paste is prepared by mixing and stirring Portland cement, heavy calcium carbonate, layered-branching composite calcium hydroxysilicate-magnesium calcium aluminate, porous cage-shaped hydrophobically modified calcium zinc aluminosilicate, latex powder, hydroxypropyl methyl cellulose ether, polypropylene fiber, calcium formate, organic silicon water-repellent agent, starch ether and water. The layered-branching composite calcium hydroxysilicate-magnesium calcium aluminate is prepared by parallel flow co-precipitation of a calcium source, an aluminum source, a magnesium source and a silicon source in the presence of a template agent and a buffer solution, and then hydrothermal calcination, so as to form a layer plate-whisker interlocking structure. The porous cage-shaped hydrophobically modified calcium zinc aluminosilicate is prepared by a sol-gel method through step-by-step temperature control complexation, template assembly, calcination and fluorosilane hydrophobic modification, so as to form a porous cage-shaped structure. The application is suitable for plugging of concrete structure bolt holes.

This invention discloses a trivalent chromium-doped magnesium calcium aluminate deep red phosphor and its preparation method. The phosphor is trivalent chromium ion-doped magnesium calcium aluminate with the chemical formula CaMg2Al. 16‑x O 27 :xCr 3+ The elemental molar ratio is Ca:Mg:Al:O:Cr = 1:2:(16-x):27:x, where 0.01≤x≤0.10. This invention also discloses a method for preparing this phosphor. The deep red luminescent phosphor of this invention exhibits absorption in the 300-650 nm region and its emission spectrum is located in the 600-880 nm region. Its emission color is in the deep red to near-infrared range, which matches the deep red absorption spectrum of plant photosynthesis. This phosphor has potential application prospects in plant LED lighting.
