Preparation method of high-temperature-resistant additive for concrete
The invention discloses a preparation method of a high-temperature-resistant additive for concrete. The preparation method comprises the following steps of: firstly, weighing the following raw materials in parts by weight: 6-10 parts of butadiene styrene rubber, 7-9 parts of polyethylene wax, 10-15 parts of petroleum resin, 10-12 parts of rosin resin, 10-15 parts of polyvinyl chloride resin, 10-20parts of naphthenic oil, 6-10 parts of filler, 3-5 parts of hydrogel, 0.6-1 part of an antioxidant and 9-11 parts of a plasticizer; secondly, heating the butadiene styrene rubber, the polyethylene wax, the petroleum resin, the rosin resin, the polyvinyl chloride resin and the naphthenic oil to 200 DEG C, and reacting for 20-30 minutes to obtain a mixture A; and thirdly, adding the filler, the hydrogel, the antioxidant and the plasticizer into the obtained mixture A, then stirring for 30-50 minutes at 100 DEG C, and cooling to room temperature to obtain the high-temperature-resistant additivefor concrete.
本发明公开一种用于混凝土的耐高温添加剂的制备方法包括如下步骤：第一步、称取如下重量份原料：丁苯橡胶6‑10份、聚乙烯蜡7‑9份、石油树脂10‑15份、松香树脂10‑12份、聚氯乙烯树脂10‑15份、环烷油10‑20份、填料6‑10份、水凝胶3‑5份、抗氧剂0.6‑1份和增塑剂9‑11份；第二步、将丁苯橡胶、聚乙烯蜡、石油树脂、松香树脂、聚氯乙烯树脂和环烷油加热至200℃，反应20‑30min，得到混合物A；第三步、向得到的混合物A中加入填料、水凝胶、抗氧剂和增塑剂，然后在100℃搅拌30‑50min；冷却至室温得到一种用于混凝土的耐高温添加剂。
