It is incorrect according to English grammar rules. When to use I/me/myself is taught in elementary school.

The basic rule is: Use myself only when you have used I earlier in the same sentence

Some simple sentences:

He had a meeting with me.
I saw myself in the mirror.
Becky gave the apple to me.
He let himself into the office.
You and I are going to the store.
