Abstract
PURPOSE: Pulp-like particles that are made by covering and binding a powder of magnesium oxide or hydroxide with a heat-resistant aromatic polymer, thus giving synthetic paper or a friction material such as brake lining with high heat resistance, electrical insulation and dimensional stability.
CONSTITUTION: For example, a heat-resistant aromatic polymer such as poly-m- phenylene isophthalamide is dissolved in a solvent such as N-methyl-2-pyrrolidone. Then, a powder of magnesium oxide and/or magnesium hydroxide is added to the solution to form the objective pulp-like particles covered and bound with the above polymer. The amount of the powder in the particles is preferably 20W80wt%. Further, the powder may be combined with other powders such as alumina or talc or fibers such as glass fiber or titanium oxide fiber.
EFFECT: The particles show high flame retardancy, flameproofing and heat resistant properties.
