Embodiment 1
[0027] The plant fiber fireproof heat insulation tile, the manufacturing process of the plant fiber fireproof heat insulation tile comprises the following steps:
[0028] A, take coconut palm fiber as raw material to make slab by paving process, the density of slab is 0.13g / cm3;
[0029] B, immersing the slab in the inorganic gelling slurry that the mass percent concentration that is formed by magnesium chloride, magnesium oxide and water is 50% and soaks, soaking time is 5 minutes;
[0030] C. Coat the surface of the soaked slab with a cement layer;
[0031] D. Enter the slab coated with cement layer into the corrugated mold to extrude the plant fiber fireproof heat insulation tile. The density of the extruded board is 0.65g / cm3 and the thickness is 0.8cm.
[0032] The coconut tree is an evergreen tree. Coconut is the fruit of the coconut tree. Its outer layer is wrapped by brown fibers. This brown fiber is coconut palm fiber. The strength of coconut palm fiber is much high...
Embodiment 2
[0051] The difference between the plant fiber fireproof heat insulation tile of this embodiment and the first embodiment is that the manufacturing process of the plant fiber fireproof heat insulation tile includes the following steps:
[0052] A, take coconut palm fiber as raw material to make slab by paving process, the density of slab is 0.14g / cm3;
[0053]B, immersing the slab into the inorganic gelling slurry that the mass percent concentration that is formed by magnesium chloride, magnesium oxide and water is 70% and soaks, soaking time is 10 minutes;
[0054] C. Coat the surface of the soaked slab with a cement layer;
[0055] D. Enter the slab coated with cement layer into the corrugated mold to extrude the plant fiber fireproof heat insulation tile. The density of the extruded board is 0.75g / cm3 and the thickness is 1.2cm.
[0056] In the step D, the extrusion pressure is 3200N / cm.
Embodiment 3
[0058] The plant fiber fireproof heat insulation tile, the manufacturing process of the plant fiber fireproof heat insulation tile comprises the following steps:
[0059] A, take coconut palm fiber as raw material to make slab by paving process, the density of slab is 0.135g / cm3;
[0060] B, immersing the slab in the inorganic gelling slurry that the mass percent concentration that is formed by magnesium chloride, magnesium oxide and water is 60% and soaks, soaking time is 7 minutes;
[0061] C. Coat the surface of the soaked slab with a cement layer;
[0062] D. Enter the slab coated with the cement layer into the corrugated mold to extrude the plant fiber fireproof heat insulation tile. The density of the extruded board is 0.7g / cm3 and the thickness is 1.0cm.
[0063] In the step D, the pressing pressure is 3000N / cm.
