TECHNICAL FIELD
[0001] The present application relates to the field of inorganic material surface modification, and particularly relates to a performance test analysis method for inorganic material surface modification. BACKGROUND
[0002] Inorganic materials are widely used in composite materials, electronic devices, building materials and other fields due to their high strength, high temperature resistance, corrosion resistance and other excellent characteristics. However, the surface of inorganic materials usually has defects such as strong hydrophilicity, poor interfacial compatibility and insufficient dispersibility, which need to be optimized through surface modification (such as coupling agent modification, plasma modification, coating modification, etc.).
[0003] In the process of surface modification of inorganic materials, different modification processes have a great influence on the performance of inorganic materials after surface modification, and whether different modifications are suitable for inorganic materials and the corresponding natural environment need to test the performance after surface modification.
[0004] The existing performance test analysis method for inorganic material surface modification has the following core defects:
[0005] Single test dimension: the traditional method only tests a single performance (such as surface energy, tensile strength, dispersibility), ignores the coupling correlation of multi-dimensional indicators such as mechanical properties, surface chemical properties and durability, resulting in one-sided evaluation of modification effect;
[0006] Insufficient prediction accuracy: long-term performance prediction mostly uses a single empirical formula, without considering the dynamic coupling influence of environmental factors such as temperature and humidity, and without integrating data-driven methods, resulting in large prediction error;
[0007] Long test cycle: long-term durability test needs to take several months or even years, which is low in efficiency and cannot meet the rapid detection needs of industrial production. SUMMARY

Specifically, this includes the following steps:
[0068] Step S21: Select three probe liquids of different polarities—deionized water, ethylene glycol, and diiodomethane—and use the seated drop method to test the surface contact angle of each modified sample. A uniformly spaced probe is placed on each modified sample. N Test points, and take N The average surface contact angle at each test point is used to obtain the surface contact angle of the modified sample tested for each probe liquid.

[0084] Step S3: constructing a durability test environment of the modified sample, calculating a time of the durability accelerated test based on the target natural environment parameters and the durability environment parameters set by the durability test, performing the durability test on the modified sample, and calculating a performance attenuation rate of the modified sample after the durability test.
[0085] Step S3 specifically comprises the following steps:
[0086] Step S31: constructing a durability test environment of the modified sample, and calculating a time of the durability accelerated test based on the target natural environment parameters and the durability environment parameters set by the durability test, performing the durability accelerated test on the modified sample in the durability test environment;
[0087] The durability environment parameters include an environment temperature , an erosion medium concentration , and a relative humidity ;
[0088] The target natural environment parameters include a target temperature , an erosion medium concentration , and a humidity of the natural environment;

[0096] Index Term This reflects the fundamental effect of temperature on the reaction rate; the higher the temperature, the larger this value. (Temperature conversion factor) The larger the value, the more significant the acceleration effect.
[0097] Concentration conversion factor The calculation method is as follows:
[0098] ;
[0099] in, This is a correction factor based on the concentration of the corrosive medium. p Porosity of the modified sample; reference correction factor Generally, 0.9 ≤ ≤1.1, porosity is obtained by testing the modified surface of the modified sample.
[0100] The concentration of corrosive media (such as chloride ions and sulfates) affects the durability degradation of modified samples by influencing the diffusion driving force (concentration gradient). However, the "concentration threshold effect" of modified samples must be considered (when the concentration is lower than the concentration of corrosive media in the natural environment, the diffusion rate increases linearly with the concentration; when the concentration is higher than the concentration of corrosive media in the natural environment, the diffusion rate tends to level off due to pore channel saturation).
[0101] Logarithmic terms reflect the concentration threshold effect: when the concentration of the corrosive medium... When, the logarithmic term grows approximately linearly; when At the same time, several factors slowed down to avoid overestimating the accelerating effect of high concentrations; porosity correction term Porosity reflects the effect of density p The larger the pore size, the more developed the pore channels, the easier the concentration diffusion, and the higher the concentration conversion factor. Slightly increased.

[0105] Relative humidity affects the transport of corrosive media by influencing the pore water saturation on the modified sample (pore water is discontinuous when dry and continuous when wet). The "critical humidity effect" of the modified sample needs to be considered (when the humidity is below the critical value, the transport rate drops sharply; when it is above the critical value, the transport rate tends to stabilize).
[0106] when At this time, the numerator is negative (which has no practical significance). (Values below 0.1 are considered to have no accelerating effect). At that time, the denser the pores, the higher the humidity sensitivity, and the larger the humidity conversion factor; the humidity of the natural environment These are generally higher than the critical relative humidity for durability environments. .
[0107] formula mesoporous p The smaller the relative humidity (the denser the material), the lower the humidity required for continuous pore water flow; the critical relative humidity... Reduce; Critical Humidity Reference Porosity p=0.2 The critical humidity is 55%.

[0114] Step S42: Construct a random forest network model, which contains two decision trees, and the two decision trees respectively use the modification process parameters and the natural environment parameters used by the modified sample to predict the performance parameters of the modified sample.
[0115] The prediction model of the two decision trees is: ;

[0117] The performance parameters predicted by the two decision trees are averaged as the output of the final random forest network model prediction Y ;
[0118] ;
[0119] The present application uses the two decision trees of the random forest network model to respectively predict the influence of process conditions and use natural environment conditions on the performance of surface modified materials, and comprehensively outputs the final performance parameters of surface modified materials by comprehensively outputting the hardness of output performance parameters under different modification process conditions. The performance of the surface modified inorganic material under different modification processes meets the requirements.

Y ; ; Step S43: Use the modification process parameters and target natural environment parameters of the durability acceleration test for each modified sample as input data. Input the performance parameter data calculated during the test into the random forest network model, train the prediction model of the two decision trees, fit the weight coefficients using the least squares method, and output the converged random forest network model.
