Method for preparing cold-resistant, heat-resistant super absorbent resin particles

Abstract

The invention discloses a method for preparing cold-resistant, heat-resistant super absorbent resin particles. The preparation method comprises the following steps: 1, preparing a base solution, namely adding a certain amount of glycerin into ethanol, and uniformly stirring to obtain a mother solution; adding the obtained mother solution into a certain amount of purified water, and uniformly stirring to obtain a mixed solution; adding a certain amount of glycerin into the mixed solution, and uniformly stirring to obtain a base solution; and 2, preparing cold-resistant, heat-resistant super absorbent resin particles, namely adding a certain amount of solid resin particles into a reaction device, pouring the prepared base solution into the container; and forming the cold-resistant, heat-resistant super absorbent resin particles after the base solution is totally absorbed by the solid resin particles. By utilizing the cold-resistant, heat-resistant super absorbent resin particles preparedby the method disclosed by the invention, the prepared cold and hot compress physical therapy appliance has excellent heat retention and cold storage performances. Moreover, outer package and fixation devices with different shapes can be made according to needs. After repeatedly used, the cold and hot compress physical therapy appliance still has excellent heat retention and cold storage performances, and the cold-resistant, heat-resistant super absorbent resin particles cannot be broken easily.

Description

Technical field [0001] The invention relates to a preparation method of resin particles, in particular to a preparation method of cold-resistant and heat-resistant super absorbent resin particles. Background technique [0002] With the development of science and technology and the progress of society, the pace of people's lives is also accelerating. The resulting human sub-health problems have also emerged. Simple sub-health problems can be relieved by simple cold and hot compresses, but the general cold and hot compresses still stay in the use of towels to absorb water or ice packs. Use towels. The cold and hot state of the carrier in this way lasts for a short time, the replacement is also cumbersome, and it cannot be fixed on the part that needs cold and hot compress. Using ice packs for cold compresses, because the ice packs are hard, the ice packs cannot be completely in contact with the cold compresses, which greatly reduces the effect of the cold compress, and it cannot b...

Problems solved by technology

Although the solid resin particles can be processed and packaged in products that can be fixed on the parts that need cold and hot compresses after absorbing water, the solid resin particles absorb ordinary water and cannot achieve the effect that cold and hot compress physiotherapy appliances will not freeze after being frozen
