| titleOfInvention | Fiber reinforced cement board and its manufacturing method |
| abstract | (57) [Summary] [PROBLEMS] Asbestos has been widely used as a building material, a fire-resistant material, a heat-insulating material, a sound-insulating material, etc. due to its excellent heat resistance, abrasion resistance, fire resistance, heat insulation, sound insulation and the like. However, as its toxicity has been revealed, its use has been restricted in many fields, making it impossible to produce corrugated asbestos slate which has been used in large quantities. Therefore, there was an urgent need to develop technology for making thin cement boards without using asbestos. When a vermiculite is expanded by a chemical or heat, its volume is increased to 7 to 20 times. However, when the vermiculite is expanded at a high temperature of 800 ° C. or higher, its surface is vitrified, hydroxyl groups are lost, and hydrophobicity is increased. The product expanded at 450 ° C. or lower using a chemical agent or the like has a crystal structure, and its surface has many hydroxyl groups and is hydrophilic. According to the present invention, a fiber-reinforced cement board having good performance can be obtained by adding the expanded vermiculite having the crystal structure to a fiber-reinforced cement board in an amount of 3 to 30% by weight, preferably 5 to 25% by weight in terms of dry matter. can get. |
