A kind of processing technology of hydrogel pad

Abstract

Disclosed is a process for manufacturing a hydrogel pad, comprising the following steps sequentially: bag making, preparing a hydrogel raw material, filling, curing, and packaging; the process uses a normal temperature polymerization accelerant and an initiator to be mixed in the bag, the chemical reaction can happen under conditions of room temperature and heat is released, so as to achieve the chemical heating to promote the formation of the hydrogel without heating by an outer heat source, and reduce the energy consumption in the production; and the process uses a conveyor belt shaping device for pressing and shaping the hydrogel, and the conveyor belt shaping device can perform shaping continuously and at a high efficiency, is easy to operate, has large work capacity, reduces the production costs and improves the production efficiency. The hydrogel obtained has a strong utility and beautiful appearance.

Description

technical field [0001] The invention relates to a processing technology of a mat, in particular to a processing technology of a hydrogel pad. Background technique [0002] Hydrogel is a new type of functional polymer material with a three-dimensional network structure. It can be obtained from one or more monomers, which are polymerized and cross-linked by a chemical initiator. Hydrogel can swell in water and maintain a certain amount of water. And insoluble in water, it has high water content, fast swelling, softness, rubber-like viscosity and good biocompatibility, and has good responsiveness to external stimuli, such as temperature, electric field, etc., so hydrogel It is widely used in various fields. For example, hydrogel can be made into a sheet-shaped hydrogel pad wrapped on the outside. This hydrogel pad has excellent heatstroke prevention and ventilation effects and is favored by people. Its principle is to use the high specific heat capacity of water in the hydroge...

Problems solved by technology

During the heating process, the heating of the heating plate will generate a large amount of energy consumption, and it will take a period of time to use the heating plate to make the monomer solution at room temperature reach the polymerization temperature, and the production efficiency is low. Therefore, this method uses two or more layers of heating plates. The process of producing gel pads by physical heating and pressure is complex in operation and high in cost, and is not suitable for new industrial production
