Problems solved by technology

After the air is pushed out of the cell and the cell is flattened, although the external force has been removed and the cell wall has restored elasticity, the air cannot return to the cell quickly due to the small vent holes, and the cell cannot quickly recover its shape. The force of the bomb is suppressed, and the time for the material to deform and recover is prolonged
[0004] Although the slow rebound sponge on the market has slow rebound characteristics, its air permeability is not good, and it absorbs water at the same time, locks water, and is difficult to dry!

Abstract

The invention discloses a slowly-rebounded sponge. The slowly-rebounded sponge comprises the following raw materials: 20-70 parts of a slowly-rebounded polyether polyol, 20-70 parts of flexile polyether polyol foam, 0.1-0.5 part of a pore opening agent, 1-4 parts of a foaming agent, 25-48 parts of isocyanate, 0.1-0.6 part of a catalyst and 0.2-1 part of a stabilizer; and a net-shaped sponge is obtained through a reaction of the above raw materials, then blasting film-removing treatment is performed, and therefore the hydrophobic slowly-rebounded sponge with a net-shaped structure and a pore diameter of 1-5mm is obtained. According to the invention, the slowly-rebounded sponge has excellent performance of springback, loosening and softness, hydrophobicity, quick drying, air permeability andthe like, and can be washed with water, so that bacteria are not bred, and accordingly health is not affected.

Description

technical field [0001] The invention relates to the technical field of sponge products, in particular to a hydrophobic breathable slow-rebound sponge and a preparation method thereof. Background technique [0002] Slow rebound sponge is also called inert sponge, memory foam, low rebound sponge, slow elastic cotton and zero pressure sponge. It was originally a high-tech material designed and developed by NASA for the space program. It is designed for astronauts to help relieve the stress experienced by astronauts during take-off, landing and flight. Due to the unique pressure relief characteristics of slow rebound sponge, it is often used to make pillows, mattresses and other household items. Slow rebound pillows and mattresses can allow the body to rest in a natural pressure-free position, and the pressure is relieved. The most important reason for people to feel comfortable. [0003] When the slow rebound sponge is deformed by external force, it will not rebound immediat...
