Embodiment 1

[0018] A method for manufacturing a composite tunnel fireproof board, comprising the steps of:

[0019] 1) Ingredients: ceramic polishing waste, ceramic clay, cement, aluminum tripolyphosphate, antimony trioxide, titanium dioxide, water glass, perlite, expanded vermiculite, kaolin, calcium carbonate, inorganic fiber, polymer fiber, mica Powder, aluminum hydroxide, magnesium hydroxide, sodium alkylnaphthalene sulfonate, and naphthalene-based water reducer are in a weight ratio of 50:50:30:8:2:3:8:10:10:5:25:30: 1: 2: 15: 15: 5: 5 mixed and added to the pulverizer for pulverization, the pulverization fineness of raw materials is controlled between 0.5-1.5mm;

[0020] 2) adding emulsion: adding 5%-10% polyester propylene ester to the powder obtained in step 1) and fully stirring;

[0021] 3) Add water and stir: add 25%-35% water to the mixture in step 2) and fully mix and stir to form a liquid;

[0022] 4) Compression molding: the liquid mixture in step 3) is dried in a drying ...

Abstract

The invention relates to a method for manufacturing a composite tunnel fireproof board, comprising the following steps of: (1) proportioning raw materials; (2) adding emulsion; (3) adding water and stirring; (4) pressing for forming: drying a liquid mixture obtained in the step 3 for 1-2 hours by a drying chamber till the water content of the liquid mixture is about 7%, and then putting into a grinding tool and pressing and forming by using a press machine; (5) drying; (6) firing by using a fire kiln; and (7) cooling and packing. The invention not only can greatly reduce the weight of the tunnel fireproof board, but also can achieve waste utilization, reduces environment pollution and greatly increase economic benefit.

Description

technical field [0001] The invention relates to a method for manufacturing a novel fireproof material, in particular to a method for manufacturing a composite tunnel fireproof board. Background technique [0002] Tunnel fireproof coating is a kind of fireproof coating used in specific occasions. In the event of a fire, it plays a role in delaying the temperature rise of the reinforced concrete main structure in the tunnel, preventing the collapse of the tunnel caused by bursting and the loss of supporting capacity of the steel reinforcement in the lining. At the same time, the environment in the tunnel is relatively closed, and it is difficult for the exhaust gas emitted by motor vehicles to escape, which will cause serious pollution and acid corrosion to the inner wall of the tunnel. However, some flame-retardant components in the tunnel fire-proof coating are alkaline oxides or hydroxides, which are resistant to long-term acid Under the action of corrosion, the performanc...
