Abstract

The invention discloses a high-strength ceiling material and a preparation method thereof. The high-strength ceiling material comprises the following raw materials in parts by weight: 35-45 parts of modified phenolic resin, 8-15 parts of polytetrafluoroethylene, 8-15 parts of silica fume, 6-12 parts of hollow glass beads, 6-12 parts of sepiolite fibers, 3-6 parts of tourmaline powder, 3-6 parts ofzinc borate, 2-4 parts of nano-zinc oxide, 4-8 parts of expanded graphite, 6-12 parts of diatomite, 20-30 parts of coconut shell flour, 5-10 parts of bamboo charcoal powder, 4-8 parts of barley green, 3-7 parts of nano-titania, 4-8 parts of carbon nano tubes, 1.5-3.2 parts of a silane coupling agent, 1.2-2.5 parts of an antioxidant and 1.8-3.6 parts of a flame retardant. According to reasonable ratio synergism of the raw materials, the ceiling material disclosed by the invention has excellent bending strength and pressure resistance, is high in strength, easy to process, green and environmental-friendly, and has an effect of refreshing air.

Description

technical field [0001] The invention relates to the field of ceiling materials, in particular to a high-strength ceiling material and a preparation method thereof. Background technique [0002] Ceilings are used as interior roof decoration materials. In the past, straw mats, reed mats, and wooden boards were used as the main materials in traditional houses. With the advancement of technology, more building materials have been applied. The ceilings commonly used in the prior art are mainly gypsum ceilings. The gypsum ceilings have the advantages of light weight, sound absorption and non-combustibility, and the materials are cheap and the decoration is elegant. However, the gypsum ceiling has the disadvantages of easy powdery cracking and poor bending resistance after reprocessing. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a high-strength ceiling material and its preparation method. The ceiling materi...
