Glass/resin composite structure and method for manufacturing same

A composite structure with high pressure resistance that is suitable for a flow channel is produced by reducing the number of components while maintaining the excellent chemical resistance and high stress tolerance inherent to a glass substrate and a resin substrate. A glass substrate surface is modified with a hydrolyzable silicon compound, and the glass substrate is brought into contact with the resin substrate. Subsequently, the contact surface between the glass substrate and the resin substrate is heated to a temperature from the glass transition temperature to the pyrolysis temperature of the resin substrate, eliminating gaps between the glass substrate and the resin substrate to bring them into close contact with each other, and causing chemical binding or anchor effects between the glass substrate and the resin substrate via the hydrolyzable silicon compound. Thus, the glass substrate and the resin substrate are firmly fixed to each other.

20170288188 · 2017-10-05 ·

Glass-fiber mats for lead-acid batteries are described. The glass-fiber mats may include a plurality of glass fibers held together with a binder. The binder may be made from a binder composition that includes (i) an acid resistant polymer, and (ii) a hydrophilic agent. The hydrophilic agent increases the wettability of the glass-fiber mat such that the glass-fiber mat forms a contact angle with water or aqueous sulfuric acid solution of 70 or less. Also described are methods of making the glass-fiber mats that include applying a binder composition to the glass fibers, and including a hydrophilic agent in the glass fiber mat that increases the wettability of the mat. The hydrophilic agent may be added to the binder composition, applied to the glass-fiber mat, or both.
