Abstract
The invention discloses an anti-tarnishing foam sponge with high elasticity recovery degree, which comprises a component A, a component B, a component C, a component D and a component E. The isomer ratio of isocyanate TDI of the component A, namely the ratio of 2,4-TDI to 2,6-TDI in the component A is 100:(10-15); the isomer ratio of isocyanate TDI of the component B, namely the ratio of 2,4-TDI to 2,6-TDI in the component B is 60:(30-40); the component C is isophorone diisocyanate; the component D and the component E are functional mixed preparations; and the component A, the component C and the component E are mixed to form a mixed group N, the component B and the component D are mixed to form a mixed group M, and the mixing mass ratio of the mixed group N to the mixed group M is 1:(1-1.3). According to the invention, the material characteristics of TDI and IPDI are utilized, a mode of mixing two groups of foams is adopted, full anti-oxidation and high-elastic recovery characteristics are realized through the mixing group M, mixing of TDI and IPDI is realized on the premise of peculiar smell removal through the mixing group N, finally uniform mixing is carried out, and peculiar smell is eliminated to the greatest extent under the condition that the characteristics of discoloration resistance and high-elastic recovery degree are met.
Description
technical field [0001] The invention relates to an anti-discoloration high-elasticity recovery foam sponge and a production process 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 a...
