Problems solved by technology
Most of the polystyrene insulation boards in the prior art use cement as a binder, and a lot of fireproofing agents are added to it. Over time, alkali resistance will occur, and the bonding strength will decrease, which will affect the quality of the insulation board. Too much inorganic fireproofing agent will increase the thermal conductivity. , and lose the effect of heat preservation

Embodiment Construction
[0013] A manufacturing process of a fire-resistant external wall insulation board is realized through the following steps: A) Prepare a fire-proof adhesive: select 15-35 parts of water glass solution with a modulus of 2.7-3.2 and stir evenly, and add 30-150 parts of it while stirring Aluminum hydroxide, keep stirring for 10-30 minutes, after standing for 60 minutes, add 100 parts of modified silica sol, 0.5-10 parts of water repellent, 5-15 parts of acid and alkali resistant short fibers, 5-30 parts of di Antimony and 10-25 parts of chlorinated paraffin, and then add 2-15 parts of bentonite, 20-80 parts of aluminum hydroxide, and 5-15 parts of styrene-butadiene latex to prepare a fireproof adhesive. In this example, choose 35 parts of modulus 3.2 water glass solution and stir evenly, add 150 parts of aluminum hydroxide while stirring, continue to stir for 30 minutes, after standing for 60 minutes, add 100 parts of modified silica sol, 10 parts of hydrophobic agent, 15 parts of...

The invention discloses a manufacturing process for an insulation board of a fireproof exterior wall, and the process is realized through the following steps: A) preparing fire adhesives; B) taking 300 to 800 portions of fire adhesives prepared in the first step, and adding 5 to 25 portions of metal oxides within 10 to 30 minutes before the using; C) adding 100 portions of polystyrene particles into the fire adhesives with the metal oxides; D) stirring admixtures well in a stirrer; E) putting the stirred admixtures of the polystyrene particles and the fire adhesives into a die, pressing the admixtures by using a 30-120 ton hydraulic press for 12 to 24 hours; and F) opening the die, putting the pressed polystyrene particles block into an air drying kiln, and drying the pressed polystyrene particles block for 48 to 72 hours at the temperature of 40 to 80 DEG C, thereby obtaining the fire insulation board. By using the manufacturing process, the fire protection level of the insulation board of the fireproof exterior wall can achieve A2, the solid polystyrene board is protected from fire, the water resistance and the cold resistance reaches the national standard, and the thermal conductivity is lower.
Description
technical field [0001] The invention relates to a manufacturing process of a fireproof external wall heat preservation board. Background technique [0002] At present, the polystyrene insulation board on the market can reach the highest fire protection level B1. Most of the polystyrene insulation boards in the prior art use cement as a binder, and a lot of fireproofing agents are added to it. Over time, alkali resistance will occur, and the bonding strength will decrease, which will affect the quality of the insulation board. Too much inorganic fireproofing agent will increase the thermal conductivity. , and lose the effect of heat preservation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production process of a fire-proof external wall insulation board with high waterproof level, good heat preservation effect and long service life. [0004] In order to solve the above problems, the present invention adop...
