Embodiment 1
[0037] see figure 1 As shown, the present invention is a high-density glass wool board, comprising a glass wool board body 1 and a fireproof layer 2, the fireproof layer 2 is arranged on the side wall of the glass wool board body 1, and the fireproof layer 2 is located on the glass wool board body 1 On the two side walls of the glass wool board body 1, the fireproof layer 2 is evenly coated on the surface of the glass wool board body 1 by means of viscose;
[0038] The method of viscose is as follows: the prepared fireproof layer 2 is mixed with the colloid, and then evenly coated on the surface of the glass wool board body 1 by a coating roller;
[0039] The fireproof layer 2 is prepared through the following steps:
[0040] Step 1: Add chloroethylamine hydrochloride and pyridine into the reaction vessel, then add deionized water to the reaction vessel, heat and reflux for 3 hours, extract with toluene three times, remove the lower aqueous phase, and adjust the pH to 2 with ...
Embodiment 2
[0046] The fireproof layer 2 is prepared through the following steps:
[0047] Step 1: Add chloroethylamine hydrochloride and pyridine into the reaction vessel, then add deionized water to the reaction vessel, heat and reflux for 3 hours, extract with toluene three times, remove the lower aqueous phase, and adjust the pH to 2 with hydrochloric acid solution , rotary evaporation to obtain a viscous product, adding isopropanol, precipitated solid, suction filtration, and washing with acetone to obtain intermediate 1; in the first step, the amount ratio of chlorethylamine hydrochloride, pyridine and deionized water was controlled 1mol: 3.5mol: 35mL;
[0048] Step 2: Add cyanuric chloride to acetone to mix and dissolve, then add 2,2,6,6-tetramethylpiperidinamine dropwise, after the dropwise addition, stir for 5 hours at a temperature of 0°C, then heat up to 40°C to obtain a mixed system of intermediate 2; in the second step of control, the ratio of cyanuric chloride to 2,2,6,6-te...
Embodiment 3
[0053] The fireproof layer 2 is prepared through the following steps:
[0054] Step 1: Add chloroethylamine hydrochloride and pyridine into the reaction vessel, then add deionized water to the reaction vessel, heat and reflux for 3 hours, extract with toluene three times, remove the lower aqueous phase, and adjust the pH to 2 with hydrochloric acid solution , rotary evaporation to obtain a viscous product, adding isopropanol, precipitated solid, suction filtration, and washing with acetone to obtain intermediate 1; in the first step, the amount ratio of chlorethylamine hydrochloride, pyridine and deionized water was controlled 1mol: 5mol: 50mL;
[0055] Step 2: Add cyanuric chloride to acetone to mix and dissolve, then add 2,2,6,6-tetramethylpiperidinamine dropwise, after the dropwise addition, stir for 5 hours at a temperature of 0°C, then heat up to 40°C to obtain a mixed system of intermediate 2; in the second step of control, the ratio of cyanuric chloride to 2,2,6,6-tetr...
