Abstract
The invention discloses a method for continuously producing pultrusion epoxy glass fiber boards for an ultra-long time. The method comprises the following steps of (1) unwinding yarns on a creel; 2) spreading and guiding yarns; 3) impregnating in double steeping vats; 4) performing; 5) curing and molding a mold; and 6) curing through a post-curing oven to obtain a qualified product, wherein impregnating in the double glue tanks in the step (3) is used for fully impregnating the yarns in steeping vats, and the steeping vats comprise a first steeping vat and a second steeping vat; firstly, the yarns are impregnated into the first steeping vat, and then the yarns impregnated into the first steeping vat are impregnated into the second steeping vat; when the yarns are impregnated in the second steeping vat, the first steeping vat is cleaned; and when the yarns which are not impregnated are impregnated into the first steeping vat, the second steeping vat is cleaned, and the operation is repeated, so that old glue is avoided. According to the method, the problem of old glue can be solved, field production can be well controlled, continuous production without shutdown is realized, and the production efficiency is further improved.
