Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] In order to solve the problems of short service life and poor weather resistance of the existing bamboo plywood, the invention provides a production method using glass fiber reinforced composite sheet as the floor of the railway boxcar, comprising the following steps:
[0024] Step 1: According to the width and design requirements of the glass fiber reinforced polyurethane sheet, pass the required number of long glass fiber ends through the yarn guide plate and then into the forming mold 4, and be continuously pulled by the traction device 8; Fiber simultaneously pulls release paper on the upper surface and the lower surface of the forming mold 4 inside.
[0025] Step 2: During the traction process, polyisocyanate, polyether polyol, foaming agent and catalyst are continuously poured into the forming mold 4 at the same time, pol...
