Abstract

The invention relates to a polyurethane shoe sole stock solution and a preparation method thereof. The polyurethane shoe sole stock solution comprises a component A, a component B and a component C, wherein the component A comprises the raw materials of polyester polyol A1, polyester polyol A2, polyether polyol A3, polyester polyol A4, a chain extension agent and a surfactant; the component B comprises the raw materials of polyester polyol B1, polyether polyol B2, polyether polyol B3, polyester polyol B4, isocyanate and a storage stabilizer; and the component C is an alcamines catalyst. When the finally prepared polyurethane shoe sole stock solution is used for polyurethane shoe sole production, the elasticity and hand feeling of a PU shoe sole are greatly improved, the rebounding rate isas high as 38%, the folding resistance is as high as 50 thousands without cracks, and therefore the stock solution has high application value and is suitable for production of outsoles of cotton-padded shoes and cloth shoes.

Description

technical field

[0001] The invention belongs to the technical field of polyurethane, and in particular relates to a polyurethane shoe sole stock solution and a preparation method thereof. The stock solution is mainly used in the shoemaking industry. Background technique

[0002] Polyurethane elastomer is a kind of elastic polymer material containing more carbamate (-NHCOO-) characteristic groups in the molecular chain, and it is a polymer material with both rubber elasticity and plastic thermoplasticity. The biggest feature of polyurethane rubber is that it maintains high elasticity (elongation can reach 400% to 1000%) within the hardness range (Shore A10 to Shore D75 degrees), and it has excellent wear resistance (about 3-3% of natural rubber). 10 times), has good mechanical strength, oil resistance and ozone resistance, and has excellent low temperature performance. Because polyurethane rubber has very good comprehensive properties, it is widely used in a wide range of in...
