Abstract

The invention discloses a high-strength mattress material and a preparation method thereof, and belongs to the technical field of mattress materials. The high-strength mattress material comprises thefollowing raw materials: toluene diisocyanate, polyolefin, a chain extender, carbon fibers, a foaming agent, a foam stabilizer, a catalyst, a surfactant, triethylenediamine, grafted polyether, silicaaerogel, graphene and sodium bicarbonate, wherein grafted polyether, the silica aerogel and graphene are in a dose ratio of (4-6):(2-4):(1-3); the mattress material is prepared through steps of mixing, stirring, heating, drying and cooling. With the adoption of a reinforcing system formed by grafted polyether, the silica aerogel and graphene, tensile strength and compressive strength of the mattress material are improved, and density of the mattress material is reduced.

Description

technical field [0001] The invention belongs to the technical field of mattress materials, and in particular relates to a high-strength mattress material and a preparation method thereof. Background technique [0002] Foam mattresses are also called sponge mattresses, which are mattresses made of foam as the main material. The foam mattress can conform to the curve of the body. While providing support, it is soft and elastic. At the same time, it can cushion the movement of the body. Even if one person turns over frequently, it will not affect the partner, and there is no noise when turning over. Therefore, foam mattresses have been favored and loved by consumers in general. [0003] Existing foam mattresses are mainly divided into three types: polyurethane foam mattresses, high-elastic foam mattresses and memory foam mattresses. Among them, the polyurethane foam mattress refers to the common memory foam mattress on the market, also known as space memory foam mattress, slo...
