Embodiment 1
[0020] According to the components specified in Table 1 below, weigh the raw materials according to the parts by weight, add phenyl phosphate dichloride and 1 / 3 part by weight of tetrahydrofuran into the mixer, the temperature is 0 °C, and the speed is 50-60r / min , time 20-30min; then add triethylamine, continue to stir; then slowly dropwise add hydroxyethyl acrylate and 1 / 3 parts by weight of tetrahydrofuran, dropwise time 1.5-2h; After reacting for 10 hours, remove the triethylamine salt by filtration, remove the unreacted monomer by evaporation; then add azobisisobutylcyanide and mix evenly, put the mixture in an oven at 80-90°C for 5-6 hours to obtain a linear homopolymer ; Add the linear homopolymer to 1 / 3 parts by weight of tetrahydrofuran, add water and hydrochloric acid to catalyze, react and stir for 5-6h; pour the above liquid into the mold, keep the room temperature for 70-72h, and then put it into a vacuum oven Dry in medium for 5-6h to get the synthetic flame reta...
Embodiment 2
[0022] The method of Example 1 was repeated according to the content of each component specified in Table 1 below, and the test results are listed in Table 1.
Embodiment 3
[0024] The method of Example 1 was repeated according to the content of each component specified in Table 1 below, and the test results are listed in Table 1.
[0025] 1. Performance testing.
[0026] 1. Testing and Characterization.
[0027] Oxygen index test: Measured according to GB / T 2406-1993 standard.
[0028] 2. The flame-retardant plexiglass prepared in Examples 1-3 was tested for performance, and the results are shown in Table 1.
[0029] Table 1 Physical and chemical indicators of flame-retardant plexiglass.
[0030]
[0031] It can be seen from Table 1 that the initial weight loss temperature of the flame-retardant plexiglass of the present invention is ≥ 180 ° C, the half weight loss temperature is > 370 ° C, the initial weight loss temperature of PMMA is 203.0 ° C, and the half weight loss temperature is > 294.0 ° C, the weight loss area of the present invention Compared with pure PMMA, the migration to high temperature shows that the introduction of the s...
