Abstract

A flame retardant adhesive tissue paper for fabricating moldable structures, particularly suitable for forming laminates for the interior of automobiles is provided. The flame retardant adhesive tissue is prepared by screen printing an aqueous paste dispersion including a flame retardant and thermoplastic adhesive dispersed therein in discontinuous pattern onto one surface of the paper. After removal of water, the drying temperatures is increased to activate the thermoplastic adhesive to adhere to the surface of the tissue with the flame retardants solids dispersed within the interior of the tissue paper. The adhesive coated tissue paper has good acoustic properties and imparts flame retardancy to a laminate including it.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a divisional of co-pending application Ser. No. 09 / 933,191, filed on Aug. 20, 2001.BACKGROUND OF THE INVENTION

[0002] This invention relates to a fire retardant adhesive tissue and a method of manufacture, and more particularly to a fire retardant tissue paper which has been treated with a dispersion of fire retardant and adhesive to provide a tissue with the fire retardant solids disbursed within the tissue paper and adhesive dots on the surface.

[0003] Tissue paper is utilized in a wide variety of industrial applications. One such application is as a portion of a laminate utilized in automobiles for improving sound insulation. In addition to its sound insulation properties, it is highly desirable that the tissue paper be treated with a flame retardant so that the final product will be flame retardant and still have good acoustic properties when in composite form.

[0004] Tissue paper typically used in automotive app...
