From what I can find this order is called The National Defense Resources Preparedness executive order.
It seems that the stated purpose of the order is very vague and is as follows:
“Purpose. This order delegates authorities and addresses national defense resource policies and programs under the Defense Production Act of 1950, as amended (the ‘‘Act’’).”
The order itself is quite lengthy. I have not taken the time to read it but the statement of purpose seems to be quite overreaching. You may want to read the rest of the act yourself. It can be found here:
