摘要（英）：

The invention discloses a foamed adhesive for HI-POLY and a manufacturing method thereof and relates to the field of polyurethane foam. The foamed adhesive is prepared from a material A and a material B, wherein the material A is prepared from the following raw materials in parts by weight: 78 to 115 parts of polyether polyol, 16 to 23 parts of polymeric MDI (4,4'-diphenylmethane diisocyanate), 15 to 24 parts of MDI and 17 to 23 parts of MDI-50; the material B is prepared from the following raw materials in parts by weight: 89 to 107 parts of dichloromethane, 33 to 46 parts of fine methyl ester and 0.5 to 2 parts of other components. According to the foamed adhesive for the HI-POLY, disclosed by the invention, mixed and generated new HI-POLY can ensure original flexibility; a bonding point does not have gelling and hardening phenomena.
