Abstract

The invention belongs to the technical field of elastic materials and discloses an ultrahigh-elasticity material and a preparation method and application thereof. The ultrahigh-elasticity material is characterized by being prepared from a material A and a material B, the material A is composed of, by weight, 70-100 parts of hexa-functional polyether polyol, 0-30 parts of high-activity polymer polyol, 0.25-0.35 part of foamer, 1-3.5 parts of crosslinking agent, 0.18-1.08 parts of catalyst and 0.1-0.5 part of silane surfactant, and the material B is polyether polyol modified diphenylmethane diisocyanate prepolymer and accounts for 30-35% of total weight of the material A. the ultrahigh-elasticity material is high in elasticity (vertical resilience rate reaches 70-85%), large in supporting force (hardness reaches 25-75Asker C) and good in enduring comfort (thermocompression permanent deformation rate is less than or equal to 6%).

Description

technical field [0001] The invention belongs to the technical field of elastic materials, and in particular relates to an ultra-high elastic material and its preparation method and application. Background technique [0002] There are many kinds of elastic materials, and for sports goods materials, EVA, polyyou (environmentally friendly recycled cotton), XPE, SBR, latex, high-density MDI foam, butadiene rubber and other materials are commonly used. Neither elasticity reached more than 75%. [0003] Polyurethane is a kind of synthetic material with a wide range of uses, and its industrial production is mainly prepared by reacting polyvalent organic isocyanate with various hydrogen donor compounds (usually such as polyol compounds containing terminal hydroxyl groups). By choosing different numbers of functional groups and different types of functional groups, and using different synthesis processes, polyurethane products with different properties and appearances can be prepare...
