Wherein, the water resistance test is to measure the expansion condition of the surface of the sample plate after the sample plate is soaked in water for 24 hours;
the bonding property test is to test the drawing strength of the coated sample plate;
testing the fire resistance of the sample plate according to a GB/T9978 building member fire resistance test method;

Application example 2
The fireproof, environment-friendly and weather-resistant organic insulation board fireproof slurry prepared in the embodiment 1 is coated on insulation boards of different materials (350 g/m)2) Cone calorimetry (50KW radiant heat) was performed, and the test results are shown in table 6:
TABLE 6
The Heat Release Rate (HRR) is one of the important indexes for evaluating the fire characteristics of a material, the peak heat release rate (PkHRR) is often used as one of the most important parameters for characterizing the fire risk of the material, according to the experimental results of the cone calorimeter of the organic insulation board of EPS, XPS and RPU in table 6, the experimental result difference between the EPS, XPS and RPU bare board and the fireproof slurry protection board is obvious, the heat release rate (AvHRR) of the fireproof protection board is reduced by about several tens of times compared with the bare board, and the peak heat release rate (PkHRR) of the fireproof protection board is greatly reduced (about 90% of the EPS and XPS fireproof protection board, and about 60% of the RPU fireproof protection board is reduced) compared with the bare board.
Because EPS, XPS, RPU panel are organic polymer material, and under 50KW radiant heat, the sample surface reaches decomposition temperature rapidly and produces combustible gas, meets naked light and can ignite, therefore EPS, XPS, RPU fire protection board are under this experimental condition, and ignition time (TTI) does not appear the condition that reduces, and this is closely related with the physics, the chemical property of material.
