摘要：

研究了高吸水树脂的质量分数对其在木板上附着性能的影响。通过流变学方法和倒置实验确定样品形成凝胶的浓度区间,同时测定了该吸水树脂的最大吸水倍率,求得其吸水饱和浓度。通过模拟消防车中喷枪喷向火灾现场进行灭火的场景,对样品进行了喷涂实验,以在固定面积范围的木板上凝胶的附着厚度来判断其附着性能的大小。结果表明:高吸水树脂的附着性能与其质量分数相关,随着质量分数的升高,样品的附着性能提高,当高吸水树脂样品的质量分数达到其凝胶浓度时,附着性能有着大幅度的提高,在质量分数继续增加时,附着性能提高的幅度较小,此时由于重力影响,附着层会整块掉落。

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
