Problems solved by technology

During the long-term use of memory foam, due to various external factors, such as mechanical action, ultraviolet light, heat, etc., the memory foam material will inevitably appear missing on the surface or have many microcracks inside. If these microcracks cannot be If it is repaired in time, the performance and service life of the cover material itself will be reduced. In severe cases, it may even fail completely, causing the material to lose its use value. However, the traditional repair methods include glue repair, resin curing, etc., which cannot fundamentally Repair these microcracks

Abstract

The invention discloses a memory foam, and belongs to the field of household article materials. The memory foam is prepared from, by weight, 38-48 parts of polyether polyol, 9-19 parts of toluene diisocynate, 0.1-0.5 part of silicone oil, 1.0-2.2 parts of a pore opening agent, 0.02-0.06 part of a catalyst, 0.8-1.4 parts of a cross-linking agent, 1.3-1.8 parts of a chain extender, 0.6-1.4 parts ofzinc oxide and 8-15 parts of modified nano-silica. A process for modifying nano-silica comprises the following steps: adding 80-150 mL of a toluene solvent and nano-silica in parts by weight into a container, performing ultrasonic dispersion for 20-40 min, adding 0.4-0.6 part of gamma-aminopropyltriethoxysilane, refluxing at 100-120 DEG C for 8 h to obtain a transparent solution, ultrasonically washing the transparent solution with toluene, centrifuging to obtain a white solid, and drying the white solid obtain the modified nano-silica. The effect of self-repairing micro-cracks in the memory foam is achieved.

Description

technical field [0001] The invention relates to the field of household goods materials, in particular to memory cotton and its processing technology. Background technique [0002] Memory foam is a polyurethane polymer with an open unit structure. This material has special viscoelastic properties and has a strong impact energy absorption capacity. It is widely used in furniture materials such as seats, sofas, and mattresses. . During the long-term use of memory foam, due to various external factors, such as mechanical action, ultraviolet light, heat, etc., the memory foam material will inevitably appear missing on the surface or have many microcracks inside. If these microcracks cannot be If it is repaired in time, the performance and service life of the cover material itself will be reduced. In severe cases, it may even fail completely, causing the material to lose its use value. However, the traditional repair methods include glue repair, resin curing, etc., which cannot f...
