METHOD AND APPARATUS FOR COATING AND IMPREGNATION OF RESIN

摘要

PURPOSE:To enable the high-speed coating, impregnation and permeation of a high-density liquid resin by oscillating the liquid resin and allowing a base material to pass therethrough to be impregnated and coated with the liquid resin in the production of composite materials or laminated boards. CONSTITUTION:A base material 2 taken out of an unwind machine 1 is contacted with and heated by heating means 3, then led into a vacuum suction section 4 where air in the base material is reduced by vacuum means 6, and thereafter led into a resin application volume regulating means 9 where a liquid resin is allowed to pass through distribution passages 17 by a volume regulating pump 11 to be applied to the base material 2 at the place of a slit 7. In addition, the liquid resin is oscillated obliquely in its advancing direction by oscillating means 8 to promote infiltration. Heating and vacuum suction can also be done under a non-contact state. Furthermore, the liquid resin is oscillated and heated by the oscillating means 8 and the heating means 3 so that the heated liquid resin 13 is directly applied to and infiltrated into the base material 2, whereby infiltration can also be further accelerated by rolls 12 to which heating and oscillation are applied.
