Problems solved by technology

[0006] However, the above-mentioned prior art has the following defects: first, the nano-silver and nano-titanium dioxide in the nano-silver protoplasm are easy to agglomerate, causing the problem of local uneven density inside the memory foam, which not only affects the mechanical properties of the memory foam, but also causes Its dehumidification and air permeability performance decrease; second, because the reversible phase is an amorphous region rich in macromolecular soft segments, the nano-silver puree is compounded in the soft segment polymer (reversible phase), and the reversible phase changes with temperature after molding. During the change of hardness and softness, nano-silver and titanium dioxide particles remain unchanged, and their dispersion uniformity in the reversible phase is affected by the size and distribution of cells, the thickness of cell walls, and the opening ratio of cells. It is very easy to have too much or too little local dispersion during the change process, which will have an adverse effect on the bearing capacity of the memory foam

Description

technical field [0001] The invention relates to the technical field of household articles, in particular to a high-load-bearing memory cotton and its preparation method and application. Background technique [0002] Memory foam, also known as "slow rebound sponge", "inert sponge" and "zero pressure foam", is a viscoelastic polyurethane soft foam with an open-cell structure. When the memory foam is impacted by pressure, two deformations will occur at the same time: one is elastic deformation (energy storage deformation), and part of the energy accumulated in it can make the memory foam material slowly return to the state before the pressure is removed after the external force is removed. The other is plastic deformation (energy dissipation deformation), which can absorb more than 90% of the impact energy, and has little rebound force on the pressure object in contact with it; therefore, the memory foam has the ability to absorb pressure and The characteristics of repeated us...
