Foam stabilizer as well as preparation method and application thereof
The invention belongs to the technical field of papermaking, and discloses a foam stabilizer and a preparation method and application thereof.The foam stabilizer is prepared from, by weight, 12.5-125 parts of bacterial cellulose dispersion liquid, 1-10 parts of surfactant and 1000-2000 parts of water, and the mass concentration of the bacterial cellulose dispersion liquid is 0.5-1%. The preparation method of the foam stabilizer comprises the following steps: adding the bacterial cellulose dispersion liquid into water, stirring, adding the surfactant, and stirring to obtain the foam stabilizer. The foam stabilizer prepared by the invention is green and environment-friendly, the bacterial cellulose is in a unique ribbon shape and can be adsorbed on the surface of bubbles generated by the surfactants in a large area by virtue of electrostatic attraction, so that the close arrangement of the surfactants is enhanced, and meanwhile, the desorption of the surfactants is also hindered; the addition of the foam stabilizer is beneficial to enhancing the tensile strength and tear resistance of the fiber preform.
本发明属造纸技术领域，公开了一种稳泡剂及其制备方法与应用，一种稳泡剂，包括如下重量份组分：细菌纤维素分散液12.5～125份，表面活性剂1～10份，水1000～2000份，所述细菌纤维素分散液质量浓度为0.5～1％。稳泡剂的制备方法包括如下步骤：将细菌纤维素分散液加入到水中，搅拌，加入表面活性剂，搅拌得到。本发明所制备的稳泡剂绿色环保，细菌纤维素呈现独特的丝带状，借助静电吸引力能够大面积的吸附于由表面活性剂生成的气泡表面，加强了表面活性剂间的紧密排列，同时也阻碍了表面活性剂的脱附，稳泡剂的加入有助于增强纤维预制体的抗拉强度和抗撕裂能力。
