Abstract

The invention discloses a sand hole and air vent resistant cement board. The sand hole and air vent resistant cement board is prepared from the following raw materials in parts by weight: 100-120 parts of cement, 20-30 parts of coal ash, 20-30 parts of glass beads, 10-15 parts of glass fibers, 5-10 parts of ultra-fine mineral powder, 8-12 parts of phenolic resin, 15-20 parts of aluminium silicate,0.2-0.5 part of sodium hydrogen sulfate, 10-15 parts of additive and 80-100 parts of water. The invention further discloses a preparation method of the sand hole and air vent resistant cement board.The prepared cement board is high in strength, smooth in surface, free of sand holes and air vents, better in durability, convenient to process subsequently and better in attractiveness under the action of cooperation of the various raw materials.

Description

technical field [0001] The invention relates to the technical field of building cement boards, in particular to a cement board resistant to trachoma and pores. Background technique [0002] As the name implies, cement board is a kind of building slab produced by processing cement as the main raw material. It is a building product between gypsum board and stone, which can be cut, drilled and carved freely. It is superior to gypsum board and wood board. Fireproof, waterproof, anti-corrosion, insect-proof, sound-proof, and the price is far lower than stone, so it has become a widely used building material in the construction industry. [0003] Tiny trachoma and pores are commonly found on the surface of existing cement boards, which not only affect its performance, but the surface of the board is easy to crack and has poor durability, and the trachoma and pores are not conducive to subsequent processing. It can also adversely affect the appearance of the building. Contents o...
