Abstract

The invention relates to a mattress inflation layer material, in particular, a rubber material suitable for a mattress inflation layer with adjustable hardness and a preparation method thereof. The rubber material comprises natural rubber, styrene butadiene rubber, a vulcanizing agent, a vulcanization promoter, dimethyl dithiodipropionate, white carbon black, an anti-aging agent, and a softening agent. The provided rubber material is prepared by a special preparation technology based on a special formula. The rubber material has good mechanical strength, excellent resilience, and a good wear resistant performance, meets the requirements on mattress inflation layer materials, and can be used to prepare a mattress inflation layer with adjustable hardness.

Description

technical field [0001] The invention relates to a material for an air-filled mattress, in particular to a rubber material suitable for an air-filled mattress with adjustable hardness and softness and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, people's requirements for the quality of life are getting higher and higher, and there have been unprecedented improvements in basic necessities of life. Sleep occupies more than 1 / 3 of human life, and the quality of sleep directly affects people's health, and the quality of mattresses is closely related to sleep. Mattress materials, hardness, compression deformation, temperature and humidity all affect people's sleep quality. [0003] There are several types of mattresses, such as palm mattresses, latex mattresses, spring mattresses, water beds, and air beds. Among them, air beds are also known as air mattresses or air mat...
