The invention relates to an auxiliary agent for cement gypsum products. The auxiliary agent is composed of 100 parts by weight of an EVA emulsion, 0.01 to 0.1 part by weight of benzotriazole, 0.01 to 0.1 part by weight of a dispersant, 0.01 to 0.1 part by weight of a leveling agent, and 0.01 to 0.1 part by weight of a film forming auxiliary agent; the mass content of the EVA in the EVA emulsion is 10 to 50%, and the number-average molecular weight of the EVA is 1000 to 8000. In the prior art, a concrete sealing curing agent is generally adopted to treat a concrete structure, and the concrete sealing curing agent is a multi-component chemical reagent, is very low in viscosity, and is difficult to deform after coating the surface of the concrete structure, due to the capillary action, the concrete sealing curing agent can rapidly permeate into the concrete structure and react with free calcium in the concrete structure to generate insoluble amorphous hydrated calcium silicate, so that pores of the concrete structure are blocked, and the hardness and the waterproofness of the concrete structure are improved.
本发明涉及一种水泥石膏制品用助剂。所述助剂由100重量份的EVA乳液、0.01‑0.1重量份的苯丙三氮坐、0.01‑0.1重量份的分散剂、0.01‑0.1重量份的流平剂、0.01‑0.1重量份的成膜助剂组成，所述EVA乳液中EVA的质量含量为10‑50％，所述EVA的数均分子量为1000‑8000。现有技术普遍采用混凝土密封固化剂来对混凝土结构物进行处理，混凝土密封固化剂是一种多成分的化学试剂，粘度很小，涂装在混凝土结构物表面后，由于毛细作用可迅速渗入混凝土结构物内部并与其内部的游离钙反应生成不可溶解的非晶态水化硅酸钙，从而实现对混凝土结构物细孔的封堵，提高其硬度和防水性。
