Title:
ストランドマットの嵩増大装置
Document Type and Number:
Japanese Patent JP3987768
Kind Code:
B2
Abstract:
A manufacturing method of a polyurethane foam injected with strand mats and a device for increasing the volume of the strand mats. The method comprises the steps of: increasing the volume of each of the strand mats to weaken the cohesion between glass fibers in each of the strand mats; continuously supplying and transferring the volume-increased strand mats; spraying a polyurethane foam solution on the continuously transferred strand mats; and foam molding the polyurethane foam solution in which the strand mats are immersed, into a polyurethane foam. Because the cohesion between the glass fibers in the strand mat is weakened and the volume of the strand mat is increased, the polyurethane foam solution uniformly permeates into the strand mats. As a result, the productivity of the polyurethane foam is improved and the variations in a variety of the mechanical properties are minimized.
