High waterproof and heat preservation fiber cement board

Abstract

The invention relates to the technical field of building boards, in particular to a high waterproof and heat preservation fiber cement board. According to the high waterproof and heat preservation fiber cement board, cement, oxidized asphalt, a release agent, a water reducing agent, sodium pyrophosphate, water, a composite hydrophobic and dust-proof base material and a hydrophobic polymer micellematerial are used as composite materials of the self-waterproof fiber cement board, wherein the composite hydrophobic and dust-proof base material is a bamboo shoot fiber treatment material, and the hydrophobic polymer micelle material and the oxidized asphalt are cooperated, so that the board has good hydrophobic performance; and a nano super hydrophobic protective layer formed by painting with asuper hydrophobic stone protective agent is arranged on the surface of the water-proof fiber cement board, wherein the super hydrophobic stone protective agent is prepared by using non-fluorosilane silicone resin as a raw material in the combination with nano-sized metal oxide sol, and the waterproof effect of the board is further improved; and a rock wool natural heat preservation layer plays agood role of heat preservation. The high waterproof and heat preservation fiber cement board has good heat preservation and waterproof performance and is suitable for promotion and use.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to a high waterproof and thermal insulation fiber cement board.
