针对自制的环保磷酸酯化淀粉胶黏剂及内墙腻子,研究其有害物质限量及性能。结果表明,磷酸酯化淀粉胶黏剂及其内墙腻子中甲醛、苯系物、VOC、铅、镉、铬、汞等有害物质未检出,打磨性、施工性等物理性能符合行业标准要求;红外光谱表明,淀粉与磷酸根发生了酯化,酯化后淀粉胶黏剂透明度高、黏度合适、流动性好,用其制备的建筑内墙腻子性能有明显改善;SEM表明淀粉胶黏剂-白水泥-重钙形成了良好的涂膜结构。磷酸酯化淀粉胶黏剂及腻子是一种绿色环保的墙体材料,有较好的应用前景。
For home-made environmentally friendly phosphate esterified starch adhesive and interior wall putty, study its harmful substances and performance. The results showed that the physical properties such as formaldehyde, benzene series, VOC, lead, cadmium, chromium, mercury and other harmful substances in phosphate esterified starch adhesive and its inner wall putty were not detected, and the polishability and workability met the requirements of the industry standard ; Infrared spectroscopy showed that starch and phosphate esterification occurred, esterified starch adhesive transparency, viscosity, flow and good, with its preparation of interior wall putty performance has improved significantly; SEM shows that starch adhesive - White cement - TCC formed a good coating structure. Phosphatized starch adhesive and putty is a kind of green wall material with good application prospects.
