Abstract

The invention discloses a hydroxyapatite-doped flame-retardant rubber plate which is prepared by mixing and adding sulfur, zinc oxide, carbon black, diphenyl guanidine, dibutyl ester, N-phenyl-2-naphthylamine, calcium carbonate and terpene resin into a chloroprene rubber adhesive main material. The hydroxyapatite-doped flame-retardant rubber plate further comprises hydroxyapatite. The obtained rubber plate has high-temperature resistance and flame retardance.

Description

technical field [0001] The invention belongs to the field of rubber, and in particular relates to a flame-retardant rubber plate doped with hydroxyapatite. Background technique [0002] Hydroxyapatite is the main inorganic component of human and animal bones. Its mineralization solution can effectively form remineralization deposits and prevent the loss of calcium ions. Its melting point is as high as 1650°C, but its strength is low and its toughness is poor. [0003] The use of rubber sheets is very common, but rubber sheets are not resistant to high temperatures, so the exploration of flame-retardant rubber sheets has never stopped, but the application of hydroxyapatite in the rubber field has not been seen so far. Contents of the invention [0004] In order to solve the disadvantage that the rubber sheet is not resistant to high temperature, the present invention provides a flame-retardant rubber sheet doped with hydroxyapatite. [0005] The hydroxyapatite-doped flame-...
