Title:
SOLUTION POLYMERIZED STYRENE-BUTADIENE RUBBER-POLYURETHANE ELASTOMERIC MATERIAL FOR HIGH PERFORMANCE TIRE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/201852
Kind Code:
A1
Abstract:
Disclosed are a solution polymerized styrene-butadiene rubber-polyurethane elastomeric material for high performance tires and a preparation method therefor. The elastomeric material is cast from the following materials: a soft segment and a hard segment in a mass ratio of 100:(20-50); the soft segment is a hydroxyl-terminated solution polymerized styrene-butadiene rubber prepared by means of an anionic polymerization; the hard segment comprises isocyanate, a small molecular polyol chain extender, and a crosslinking agent; the molecular weight of the soft segment ranges from 1,000 to 8,000; and the glass transition temperature of the soft segment ranges from -20 to -30 °C. On the basis of the synthesis of the traditional polyurethane elastomer, the hydroxyl-terminated solution polymerized styrene-butadiene rubber is introduced into the elastomeric material of the present invention as the soft segment to adjust the glass transition temperature of the polyurethane elastomer, which overcomes disadvantages of the existing polyurethane tires such as poor high-temperature resistance, unsatisfactory skid resistance ability and the like, such that the elastomeric material has integrated excellent performance for applications.
