Abstract Taking acrylic emulsion as modifier, effects of dosage on the mechanical strength, water resistance and flame retardation of magnesium-based inorganic adhesive composite board and the setting time of magnesium-based inorganic adhesive were discussed. Then the causes of those effects were analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results showed that silicone-acrylic emulsion could form an organic and inorganic interpenetrating network structure with magnesium-based inorganic adhesive. With the increasing dosage, the film-forming property of silicone-acrylic emulsion improved, and the bon-ding property of magnesium-based inorganic adhesive and the integrity of the material increased, thus the mechanical properties and water resistance were improved. Meanwhile, the increase of dosage would also delay the setting time of magnesium-based inorganic adhesive, but it had no effect on the crystalline phases. Moreover, magnesium-based inorganic adhesive also provided the straw board with good performance of flame retardation and smoke suppression. The addition of silicone-acrylic emulsion showed no significant effect on the flame retardation of the composites.

Key words： magnesium-based inorganic adhesive silicone-acrylic emulsion mechanical strength water resistance setting time flame retardation
