Abstract

The invention discloses a blending type clothing lining elastic foaming material which comprises a TDI group and an MDI group which are blended, and the mass ratio of the TDI group to the MDI group is 20:(6.5-12); the TDI group comprises the following components in parts by mass: 1000 parts of isocyanate TDI, 100-120 parts of polyether, 2-5 parts of ethylene glycol, 3-5 parts of phenol and 1-2 parts of polysiloxane copolymer, and the isomer ratio of 2, 4-TDI to 2, 6TDI of the isocyanate TDI is 100:(25-35); and the MDI group comprises the following components in parts by mass: 1000 parts of diphenylmethane diisocyanate, 30-35 parts of polyether, 2-5 parts of ethylene glycol, 2-3 parts of phenol, 5-6 parts of silicone oil and 2-3 parts of dichloromethane. The material has the characteristics of high resilience and high elastic recovery degree, is soft and comfortable in contact, has TDI characteristics and MDI characteristics, is washable and anti-deformation, and can prolong the service life of clothes. A blending foaming process is performed after the TDI group and the MDI group are respectively foamed, so that the requirement of fiber uniformity is met, the stable and reliable quality of the elastic foaming material is ensured, the raw material cost of the foaming material is reduced, and the market competitiveness is relatively high.

Description

technical field [0001] The invention relates to a blended clothing lining elastic foam material and a preparation method thereof, and belongs to the technical field of clothing lining foam sponges. Background technique [0002] Apparel linings include cups, elastic gaskets, joint surrounds, etc., which need to provide relatively reliable elastic support, and must also meet the performance of water resistance and anti-discoloration. [0003] Traditional clothing linings are made of TDI and other materials through foaming process, but TDI and other materials have poor oxidation resistance, and anti-yellowing agents need to be added during the production process. Generally, phenol is used as an anti-yellowing agent, which will produce yellowing when it meets water. Irritant odor and irritating substances will remain in the foam sponge. In addition, the elastic recovery of the foam sponge made of TDI and other materials is insufficient, and there will be deformation after long-t...
