Experiment 1
The ecological fire-proof plate prepared in the above examples and comparative examples is placed in a UV aging oven for 48h, the temperature of the aging oven is controlled at 40 ℃, the humidity is controlled at 75%, then the 28d compressive strength (MPa) and the 28d flexural strength (MPa) of the aged ecological fire-proof plate are detected according to GB/T11971-1997 aerocrete mechanical property test method, then the sample is placed in water at 25 ℃ for soaking for 5 days, the compressive strength (MPa) and the flexural strength (MPa) of the sample after soaking in water are detected again, and the change rate (%) of the compressive strength or the flexural strength before and after soaking in water of the sample is calculated, wherein the change rate of the compressive strength is calculated as (%) before soaking in water (compressive strength before soaking in water-compressive strength after soaking in water) ÷ compressive strength before soaking in water (%) × 100%, and the change rate of the flexural strength is calculated as)/(flexural strength before soaking in water-flexural strength before soaking in water) ÷ × 100%.
Experiment 2
And observing and recording whether the sample treated by the soaking water in the experiment 1 has the frosting condition or not.
Experiment 3
The fire resistance ratings of the fire doors prepared in the above examples and comparative examples were tested according to 5.11 fire resistance and 6.12 fire resistance in GB/T12955-2015 fire door.
According to the data comparison of the embodiments 4-6 in table 1, by adding N, N-dimethyldodecylamine, it is beneficial to better promote the synergistic cooperation of rosin, snail secretion mucus extract and resveratrol, thereby being beneficial to improving the waterproof performance of the ecological fireproof plate, so that moisture is less likely to corrode the ecological fireproof plate and affect the compressive strength and the flexural strength of the ecological fireproof plate, and simultaneously, it is beneficial to better improve the antioxidant performance of rosin, so that rosin is less likely to be oxidized, and further, the waterproof performance of the ecological fireproof plate is less likely to be affected, so that the compressive strength and the flexural strength of the ecological fireproof plate are less likely to be affected, and the durability of the ecological fireproof plate is better prolonged.
As can be seen from the comparison of the data in table 1 between example 4 and examples 7-8, the addition of the rosehip extract is beneficial to better improve the oxidation resistance of the rosin, so that the waterproof performance of the ecological fireproof plate is less susceptible to influence, the compressive strength and the flexural strength of the ecological fireproof plate are less susceptible to influence, and the durability of the ecological fireproof plate is better prolonged.
According to the comparison of the data of the embodiment 4 and the data of 9-14 in the table 1, the oxidation resistance of the rosin is not greatly affected by adding the citric acid or the magnesium sulfate alone, and only when the citric acid and the magnesium sulfate are cooperatively matched with each other, the oxidation resistance of the rosin can be better improved, so that the waterproof performance of the ecological fireproof plate is less susceptible to influence, the compressive strength and the breaking strength of the ecological fireproof plate are less susceptible to influence, and the durability of the ecological fireproof plate is favorably and better prolonged.
According to the comparison of the data of the embodiment 4 and the embodiments 15 to 20 in the table 1, the compression strength and the breaking strength of the ecological fireproof plate are improved by adding the norcycline alone, the compression strength and the breaking strength of the ecological fireproof plate are improved better by adding the pygeum extract and the norcycline to cooperate with each other, so that the ecological fireproof plate is less prone to surface shedding or cracking when the fireproof door is impacted strongly, the durability of the ecological fireproof plate is improved better, and the compression strength and the breaking strength of the ecological fireproof plate are hardly affected when the pygeum extract is added alone.
According to the comparison of the data of the example 4 and the comparative examples 1 to 4 in the table 1, only when the rosin, the mucus extract secreted by the snail and the resveratrol are synergistically matched with each other, the waterproof performance of the ecological fireproof plate can be better improved, the antioxidant performance of the rosin can be better improved, the compressive strength and the flexural strength of the ecological fireproof plate are less susceptible to influence, any component is absent, the waterproof performance of the ecological fireproof plate and the antioxidant performance of the rosin are easily greatly influenced, and the compressive strength and the flexural strength of the ecological fireproof plate are easily greatly influenced.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
