Title:
POLYCHLOROPRENE LATEX, RUBBER-ASPHALT COMPOSITION AND CONSTRUCTION METHOD THEREOF, SHEET, AND WATERPROOF COATING FILM
Document Type and Number:
WIPO Patent Application WO/2012/017705
Kind Code:
A1
Abstract:
A polychloroprene latex, with which a rubber-asphalt composition having excellent stability at a low temperature and excellent properties of forming a film on an adherend is obtained; a rubber-asphalt composition and a construction method thereof; a sheet; and a waterproof coating film are provided.
The rubber-asphalt composition is constituted by mixing 10 to 40% by mass of an anionic polychloroprene latex containing potassium ions in an amount of 0.7 to 1.5 parts by mass and sodium ions in an amount controlled to 0.2 parts by mass or less per 100 parts by mass of the solid content with 60 to 90% by mass of an anionic asphalt emulsion to form a main agent and using, as a solidifying agent, an aqueous solution containing a polyvalent metal salt as a main component.
