Temperature-control anti-crack waterproof agent
The invention discloses a temperature-control anti-crack waterproof agent which comprises the following raw materials: 2-10 wt% of a temperature-control component, 50-68 wt% of an expansion component and 30-40 wt% of a dense anti-seepage component, the temperature control component comprises 2-80 wt% of an inhibiting component I, 2-80 wt% of an inhibiting component II and 1-50 wt% of an adjusting component; the inhibiting component I is a polyhydroxy compound, and the inhibiting component II is ester of the polyhydroxy compound; the adjusting component is a thickening time control agent; the expansion component comprises hydration regulation and control type calcium expansion clinker, gypsum and limestone powder; and the dense impervious component comprises sodium bentonite, calcium formate, semi-dense silica fume and the like. Aiming at concrete engineering application conditions, concrete temperature rise is reduced on the basis of three aspects of temperature control, expansion and compaction impervious performance, the hydration regulation type calcium expansion clinker regulates the expansion reaction rate at 40-60 DEG C, the expansion period is better matched with the shrinkage period of the concrete, the cracking phenomenon of the concrete is reduced from two aspects of reducing the temperature rise of the concrete and compensating the shrinkage of the concrete, and the impervious performance of the concrete is improved by virtue of a dense impervious component, so that engineering requirements are met.
本发明公开一种温控抗裂防水剂，原料包括温控组分2‑10wt％、膨胀组分50‑68wt％、密实抗渗组分30‑40wt％；温控组分包括抑制组分Ⅰ2‑80wt％、抑制组分Ⅱ2‑80wt％、调节组分1‑50wt％；抑制组分Ⅰ是多元羟基化合物，抑制组分Ⅱ是多元羟基化合物的酯；所述调节组分是调凝剂；膨胀组分包括水化调控型钙质膨胀熟料、石膏、石灰石粉；密实抗渗组分包括钠基膨润土、甲酸钙、半加密硅灰等。本发明针对混凝土工程应用条件，基于温控、膨胀、密实抗渗三个方面，降低混凝土温升，水化调控型钙质膨胀熟料在40‑60℃下对膨胀反应速率已进行调控，膨胀期与混凝土的收缩期更匹配，从降低混凝土温升、补偿混凝土收缩两方面降低混凝土开裂现象，辅以密实抗渗组分提高混凝土抗渗性能，满足工程需要。
