Anti-photooxidation impermeable door and window joint sealant and preparation method thereof
The invention relates to an anti-photooxidation impermeable door and window joint sealant which is prepared from the following components in parts by weight: 15-35 parts of cement, 20-40 parts of rare earth inorganic mineral glue, 10-25 parts of quartz powder, 20-40 parts of modified light-blocking active material, 1.0-3.0 parts of light stabilizer, 0.5-1.0 part of heat stabilizer, 0.5-1.5 parts of early strength agent and 15-40 parts of terahertz active functional water. The preparation method comprises the steps of mixing, stirring and negative-pressure exhausting. The selected inorganic raw materials all belong to chemical ionic bonds, have good chemical stability and strong photooxidation resistance, and are subjected to ultraviolet irradiation treatment for 480 hours in a laboratory, and are repeated for three times or placed in a natural environment for a complete year; the gloss retention rate of the caulking glue is 85.7-91.2 and is greatly higher than that of a contrast 68.2, and the photooxidation resistance effect is very obvious; secondly, the photooxidation-resistant anti-seepage joint sealant for doors and windows has higher viscosity and leakproofness than the conventional sealant, and the anti-seepage grade still reaches the P8-P7 grade after treatment, so that the safe use time of doors and windows is greatly prolonged.
一种抗光氧化防渗门窗填缝胶由重量比水泥15‑35、稀土无机矿物胶20‑40、石英粉10‑25、改性阻光活性料20‑40、光稳定剂1.0‑3.0、热稳定剂0.5‑1.0、早强剂0.5‑1.5、太赫兹活性机能水15‑40；经混合、搅拌、负压排气制备而成；由于选用了无机原料均属于化学离子键组成，化学稳定性好，具有强抗光氧化能力，经实验室480h紫外光照射处理，重复三次或在自然环境中放置一完整年；所述填缝胶保光率在85.7‑91.2，大大高于对照68.2，抗光氧化效果十分明显；其次，抗光氧化防渗门窗填缝胶具有比常规胶体更强粘度和密封性，经处理后防渗等级仍然达到P8‑P7级，使门窗防安全使用时间大幅延长。
