Abstract

Abstract:

The effect of the mass fraction of super absorbent resin on the adhesion of wood board was studied. The concentration range of the gel formed by the sample was determined by the rheological method and inverted experiment. The maximum water absorption ratio of the superabsorbent polymer was measured and the water absorption saturation concentration was determined. Through the simulation of the fire engine spray gun to the scene of the fire scene, the sample was sprayed to determine the adhesion performance of the gel on the fixed area of the board. The results show that the adhesion performance of the superabsorbent resin is related to its mass fraction. As the concentration increases, the adhesion performance of the sample increases. When the mass fraction of the superabsorbent resin sample reaches its gel mass fraction, the adhesion performance is greatly improved. When the increase is continued, the adhesion performance is increased to a small extent, and the adhesion layer falls off in a monolith due to the gravity.

Key words: superabsorbent polymer, mass fraction, adhesion performance, water absorption ratio
