A preparation method of phenolic fiber, comprising the steps of uniformly mixing phenolic resin and spinning improver, the mixed materials are melted and blended by a twin-screw extruder to form a melt, and then the melt enters a single-screw extruder, The fiber is sprayed out through the spinneret assembly, sucked through the aspirator, and transported to the fiber collection device by the wire feeding pipeline to obtain the phenolic fiber precursor; the prepared phenolic fiber precursor is cured in formaldehyde, hydrochloric acid, and deionized water. The pre-crosslinking reaction is carried out first in the solution, and then the second crosslinking reaction is carried out by adopting a stepwise heating method, and finally the third crosslinking treatment is carried out at high temperature. This patent effectively improves the spinning efficiency of the phenolic fiber precursor, shortens the crosslinking reaction time of the phenolic fiber, and prepares the phenolic fiber with excellent mechanical properties and high char formation rate.

The invention provides an extrusion process for producing an asymmetric special-shaped seamless tube by utilizing a circular tube. The extrusion process specifically comprises the steps of A. making auxiliary coordinate axes X and Y by using the center of a circle of an outlet of an extrusion container as an original point, wherein the axis X is a horizontal axis, the axis Y is a vertical axis, and a plane P on which the axis X and the axis Y are positioned is parallel to the end surface of the extrusion container; B. adjusting the positions of an ejector pin and a mold along the direction parallel to the plane P, so that the area of the cross section of a mold cavity is equally divided by the axis X and the axis Y, and the mold is fixedly connected to the outlet end of the extrusion container; C. leading the circular tube which is heated to first temperature into the extrusion container, and pushing the circular tube out of the outlet end of the extrusion container at first advance speed, so as to obtain the asymmetric special-shaped seamless tube. According to the extrusion process provided by the invention, the ejector pin can be prevented from rotating in an extrusion process, so that an inner cavity of a product is prevented from twisting, thereby guaranteeing normal production.
