Abstract

The invention belongs to the field of polymer materials and particularly relates to an organic silicon / montmorillonite composite modified polyester-type polyurethane elastomer as well as a preparation method and an application thereof. The polyurethane elastomer comprises the following components: 100 parts by mass of polyester-type polyurethane prepolymer, 0.5-100 parts by mass of isocyanate-terminated polydimethylsiloxane, 1-40 parts by mass of polyester polyol, 0.5-15 parts by mass of organic montmorillonite, 0.1-1.5 parts by mass of a defoaming agent, 0-5 parts by mass of a chain extender and 2-15 parts by mass of a curing agent. According to the polyurethane elastomer, since the polyurethane is jointly modified by virtue of organic silicon and montmorillonite, the polyurethane elastomer integrates the excellent performances of organic silicon, montmorillonite and polyurethane and thus the material has a plurality of performances, such as excellent surface property, heat resistance and good mechanical properties.

Description

technical field

[0001] The invention belongs to the field of polymer materials, and in particular relates to a silicone / montmorillonite composite modified polyester polyurethane elastomer and a preparation method and application thereof. Background technique

[0002] Polyurethane elastomer is a kind of polymer material ranging from rubber to plastic. It has good mechanical properties, wear resistance, fatigue resistance, oil resistance, aging resistance, etc. It has a wide range of uses and can be used for solid tires, printing, Rubber rollers, washer ball joints, bush bearings, sole gears, etc. However, its high internal heat generation, low temperature resistance, flammability, poor surface properties and dielectric properties limit its application in some fields.

[0003] Silicone has the characteristics of low surface energy, high and low temperature resistance, weather resistance, hydrophobicity, and electrical insulation. The use of silicone to modify polyurethane ca...
