High-molecular hydrogel fire extinguishing agent and preparation method thereof

Abstract

The invention provides a high-molecular hydrogel fire extinguishing agent and a preparation method thereof. The high-molecular hydrogel fire extinguishing agent is prepared from the compositions in percentage by weight: 0.2-1% of super absorbent resin, 0.1-1% of curdlan, and the balance of water. In order to enhancing wall adhesion performance of the fire extinguishing agent, and solving the problems that the retention time of the fire extinguishing agent on the surfaces of burning objects and the surfaces of protected objects is too short, and consequently the fire extinguishing agent cannotbe effectively utilized to extinguishand retard firein time, the curdlan is creatively added, the curdlan can obviously improve the adhesiveness of the high-molecular hydrogel fire extinguishing agentand plays an important role in improving the fire extinguishing efficiency of the high-molecular hydrogel fire extinguishing agent, the curdlan acts synergistically with other components, thus the high-molecular hydrogel fire extinguishing agent has good adhesion on vertical wall spaces and the surfaces containing stainless steel, and the fire extinguishing efficiency is good.

Description

technical field [0001] The invention relates to the technical field of polymer fire extinguishing materials, in particular to a polymer hydrogel fire extinguishing agent and a preparation method thereof. Background technique [0002] Water remains by far the most commonly used fire extinguishing agent. Water has the advantages of wide sources, low price, and strong fire extinguishing ability, but it has high fluidity, and it will be lost when it is sprayed out. The utilization rate is low, and it is not suitable for water-scarce areas. [0003] Superabsorbent resin has strong water absorption and water retention, and its unique three-dimensional network structure can firmly bind water, so that it has a huge heat capacity. Polymer hydrogels based on polyacrylic superabsorbent resins have been widely used in the field of fire extinguishing. However, there are also some disadvantages in the fire extinguishing hydrogel based on polyacrylic superabsorbent resin: when the surfac...

AI Technical Summary

Problems solved by technology

However, there are also some disadvantages in the fire extinguishing hydrogel based on polyacrylic superabsorbent resin: when the surface that has caught fire, especially the vertical wall, the surface containing stainless steel (such as the surface of the oil tanker), due to water Vaporized at high temperature, polyacrylic acid-based superabsorbent resin is difficult to adhere to its surface, so it cannot effectively cover, cool and cool down

[0004] Chinese patent CN103483752A discloses a method for improving the poor surface adhesion of polymer fire extinguishing hydrogel by adding a water-based adhesion promoter based on a silane coupling agent, but the silane coupling agent is expensive, which increases the production cost of the fire extinguishing agent , at the same time, the adhesion of the improved polymer fire extinguishing hydrogel is not satisfactory, and the fire extinguishing efficiency also needs to be improved
