Abstract

The invention belongs to the technical field of polyurethane products, and in particular relates to a polyurethane shoe-pad with low compression deformation and high elasticity and a preparation method thereof. It is made of A component and B component with a weight ratio of 100:70~90; A component is made of the following raw materials: polyether polyol, polytetrahydrofuran polyol, polymer polyether polyol, foam stabilizer , highly active silane stabilizer, crosslinking agent, chain extender, foaming agent and retardation catalyst, the crosslinking agent is composed of crosslinking agent A and tetrafunctional polyether polyol NT403; component B is made of the following raw materials : Polyether polyol, diphenylmethane diisocyanate, carbodiimide modified diphenylmethane diisocyanate and small molecule alcohol. Low compression deformation and high elasticity polyurethane insole composite material adopts low odor and low volatility environmental protection raw materials, the production process is simple, and the pouring can be completed at room temperature, which reduces the energy waste caused by heating the mold, reduces the production cost, and improves the production efficiency .

Description

technical field [0001] The invention belongs to the technical field of polyurethane products, and in particular relates to a low-compression-deformation high-elasticity polyurethane insole composite material and a preparation method thereof. Background technique [0002] Polyurethane resins include elastomers, foams, coatings and fibers, etc., and have been widely used in the petroleum industry, automobile industry, aerospace industry, etc., and can be seen everywhere in all aspects of people's lives, and insoles are closely related to people's lives. However, traditional insoles are generally cloth insoles, which have low comfort and poor elasticity. The polyurethane insole is more and more popular among the people because of its comfort and durability. [0003] Osole is a production process for preparing polyurethane foam insoles. Generally, large molds are used to cast polyurethane foam into compression molding, with a density of 90-180kg / m 3 After forming, it is cut i...
