Manufacturing method for reinforced fiber magnesium fireproof board

Abstract

The invention relates to a manufacturing method for a reinforced fiber magnesium fireproof board. The method includes the following steps that three tons of magnesium sulfate and 1.6 tons of hydrated slurry are placed in a pulping tank, then a mixture is pumped into a stirring tank, and 120kg of magnesium oxide, 25kg of saw dust powder, 80kg of magnesium sulfate and 25kg of bamboo fibers are added; after uniform stirring, a mixture is placed into the upper layer of a hopper, uniformly stirred raw materials flow into a template of a grid cloth at the lower layer of the hopper, and a semi-finished product of the reinforced fiber magnesium fireproof board is primarily formed through pressing forming of a rolling barrel; the semi-finished product of the reinforced fiber magnesium fireproof board is fed into a curing chamber, the temperature in the curing chamber is constant at of 40 DEG C, temperature-controlled drying and curing forming is conducted for 12 hours, and the reinforced fiber magnesium fireproof board which is subjected to curing forming is demolded uniformly; and finally the finished board is sent into a finished product warehouse to be cured for one week, and then cutting, forming and packaging are carried out. The method has the beneficial effects that the reinforced fiber magnesium fireproof board is environmentally friendly, fireproof, waterproof, capable of preserving heat, not prone to deformation and resistant to corrosion, and can be used as a ventilation pipeline, a decoration plate, an outer wall insulation board and the like.

Description

technical field [0001] The invention belongs to the field of fireproof boards, in particular to a method for manufacturing a reinforced fiber magnesium fireproof board. Background technique [0002] Existing fireproof boards have been more and more widely used in the field of construction, but the disadvantages of ordinary fireproof boards are: low fire rating and easy deformation. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a method for making reinforced fiber magnesium fireproof board. [0004] The object of the present invention is accomplished through the following technical scheme, the manufacturing method of this reinforced fiber magnesium fireproof board, the processing method steps are as follows: put 3 tons of magnesium sulfate and 1.6 tons of hydration pulp into the slurry tank and then pump them in for stirring Add 120kg of magnesium oxide, 25kg of sawdust powder, 80kg of ...
