Abstract
PURPOSE: To obtain continuously the titled laminate having improved heat resistance, material characteristics, etc., by transporting continuously only specific number sheets of paper bases in continuous form, which is previously impregnated with a methylol compound, impregnating the bases with a solution of an unsaturated polyester resin, followed by laminating.
CONSTITUTION: A paper base in continuous form, consisting essentially of cellulose fiber, is previously impregnated with a blend comprising (A) 100pts.wt treatment consisting essentially of a methylol group-containing compound (preferably, methylol melamine, and/or methylol guanamine) or of a methylol compound and (B) 3W 40pts.wt higher fatty acid derivative, e.g., caprylic acid, etc. as a modifier for punchability. 4W8 Sheets, preferably 5W6 sheets of the paper bases are transported continuously, and they are impregnated with a solution of an unsaturated polyester resin. The impregnated bases are laminated and cured continuously, to give the desired laminate having a thickness preferably 1.46W1.74mm.
