Novel hydrolysis resistant polyurethane composite material, preparation method and application thereof in hydrolysis resistant cable products

Abstract

The invention belongs to the field of polymer materials, in particular to a novel hydrolysis resistant polyurethane composite material, a preparation method and an application thereof. The novel hydrolysis resistant polyurethane composite material comprises the following components in parts by weight: 100 parts of polyether polyurethane elastomers, 10-40 parts of phenol compounds, 15-60 parts of aldehyde compounds, 10-25 parts of silane coupling agents, 5-15 parts of flame retardants, 2-10 parts of antioxidants, 1-10 parts of fillers and 1-10 parts of stabilizers. The novel hydrolysis resistant polyurethane composite material can be stably applied to underwater and humid environments for a long time, and waterproof cable products prepared from the novel hydrolysis resistant polyurethane composite material exhibit good flexibility, so that the material can be used for preparing flexible hydrolysis resistant cables, and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a novel hydrolysis-resistant polyurethane composite material, its preparation method and application. [0002] technical background [0003] As a high-strength, high-tear, wear-resistant polymer material, polyurethane is widely used in daily life, industrial and agricultural production, medicine and other fields, and has attracted more and more attention. Polyurethane is a kind of high polymer obtained by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compound, but the defects of polyurethane in water resistance, heat resistance and antistatic performance limit its further development and application. [0004] At present, methods such as epoxy resin, silicone, acrylate and inorganic ion filling are generally used to modify polyurethane, which improves the performance of polyurethane to a certain extent and broadens its ap...

Polyurethane is a kind of high polymer obtained by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compound, but the defects of polyurethane in water resistance, heat resistance and antistatic performance limit its further development and application

[0004] At present, methods such as epoxy resin, silicone, acrylate and inorganic ion filling are generally used to modify polyurethane, which improves the performance of polyurethane to a certain extent and broadens its application field, but the existing modification methods are still There are deficiencies such as high cost of modification, high cost of modification process control, performance improvement but still not universally applicable to application fields with special requirements, etc., which still limit the development and application of polyurethane
