Abstract

PURPOSE: The titled composition showing improved nondripping properties and toughness even in fire, exhibiting functions to prevent the spread of fire, obtained by blending a curable polychloroprene liquid at normal temperature with a hydrated metallic oxide, inorganic filler and heat-resistant fibers in a specific ratio.
CONSTITUTION: (A) 100pts.wt. curable polychloroprene liquid at normal temperature (preferably one having a viscosity at 25°C 10,000W300,000cps) is blended with (B) 200W700pts.wt., preferably 250W450pts.wt. hydrated metallic oxide (preferably those having different particles diameters such as hydrated metallic oxides having particles diameter 10W80μ and particle diameter not more than 10μ are used together), (C) not more than 80wt%, preferably not more than 50wt% (based on component B) inorganic filler (preferably clay, zinc borate and/or bentonite), and (D) 20W100pts.wt., preferably 20W60pts.wt. heat-resistant fibers (preferably a mixture of 100pts.wt. glass fibers and 10W300pts.wt. asbestos fibers, in such a way that the total amt. of components B and D is 250pts.wt., to give the desired composition.
