Problems solved by technology

[0003] In the prior art, glass wool boards are usually coated with a layer of fireproof layer on the surface of glass wool boards by colloid because of their insufficient flame retardant performance, so as to achieve the effect of fire prevention, and this method also has the disadvantage of long-term use. , because the growth of bacteria affects its flame retardant efficiency, and when it encounters a fire, the colloid is more likely to fail, making the surface fireproof layer easy to fall off, which cannot achieve a good fireproof effect

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...

Abstract

The invention discloses a high-density glass wool board. The high-density glass wool board comprises a glass wool board body and fireproof layers, the fireproof layers are arranged on the side walls of the glass wool board body and located on the two side walls of the glass wool board body, and the fireproof layers are evenly coated on the surface of the glass wool board body in an adhesive mode; a gluing mode specifically comprises the steps that the prepared fireproof layer is mixed with glue, then the surface of the glass wool board body is evenly coated with the mixture through a coating roller, the fireproof layer has the anti-corrosion and anti-bacterial effects and also has the flame-retardant and fire-resistant effects, the fireproof layer is bonded to the glass wool board through fireproof glue, and when the glass wool board is in fire, the glass wool board also has good adhesion performance, so that the fireproof performance of the glass wool board is further improved.
