Low-temperature-resistant memory foam for pillow as well as preparation method and application of low-temperature-resistant memory foam

The invention relates to the field of high polymer materials, in particular to low-temperature-resistant memory foam for a pillow and a preparation method and application of the low-temperature-resistant memory foam. The low-temperature-resistant memory foam is prepared from the following raw materials: polyether polyol, modified diphenylmethane diisocyanate, a catalyst, an opening agent, a foam stabilizer, water, carbon fiber powder, polyisocyanate grafted graphene and a silane coupling agent. The preparation method of the low-temperature-resistant memory foam for the pillow comprises the following steps: preparing the raw materials in proportion, sequentially mixing the raw materials, conducting reacting, then performing stirring and degassing, carrying out foaming and curing in a mold, and finally performing demolding to obtain the low-temperature-resistant memory foam. According to the application of the low-temperature-resistant memory foam, the low-temperature-resistant memory foam for the pillow is app
