This invention provides an environmentally friendly rubber additive based on corn cobs, its preparation method, and its application, belonging to the field of rubber additive technology. The preparation method of this invention uses corn cobs as the sole core raw material. Corn cob powder is treated with an acidic solution to obtain filter residue A; filter residue A is treated with an alkaline solution to obtain lignin solution and cellulose; cellulose is enzymatically hydrolyzed to obtain glucose; glucose undergoes isomerization and dehydration reactions to obtain 5-hydroxymethylfurfural; the lignin solution is acid-precipitated and then subjected to amination or phenolation modification to obtain modified lignin; 5-hydroxymethylfurfural and modified lignin undergo a condensation reaction under the action of an acidic catalyst to obtain the environmentally friendly rubber additive. The preparation method of this invention achieves full resource utilization, producing a rubber additive with good environmental performance, high reactivity, and excellent adhesive properties, reducing dependence on petrochemical raw materials and reducing environmental pollutant emissions.

The present application relates to the technical field of disease risk prediction, and particularly relates to a ten-year risk prediction method, system and device for sudden cardiac death, the method comprising: obtaining 48-hour electrocardiogram data of an individual sample and a risk classification evaluation result based on a China-PAR risk assessment model; splitting and combining the electrocardiogram data to obtain a preset multi-dimensional waveform graph; constructing a convolutional neural network model, taking the waveform graph as input and the corresponding risk classification evaluation result as output to train the model and obtain a sudden cardiac death risk prediction model; inputting the processed waveform graph of 48-hour electrocardiogram data of a subject into the prediction model, and outputting the result as a ten-year sudden cardiac death risk prediction level result. The present application can create a non-linear, high-precision, and iterative sudden cardiac death risk deep learning model for the general population and doctors, improve the detection rate of sudden cardiac death, and reduce the recurrence rate and mortality.
