Concrete prefabricated wallboard for fixing and sealing CO2 and production process of concrete prefabricated wallboard
The invention relates to the technical field of concrete production processes, and provides a concrete prefabricated wall panel for fixing and sealing CO2 and a production process of the concrete prefabricated wall panel. Titanium dioxide is modified through dopamine, so that the titanium dioxide has higher adhesive force; the modified titanium dioxide enables molecules in the antibacterial component and the anti-ultraviolet component to be tightly attached to the surface of the portland cement, so that the modified portland cement has better antibacterial performance and anti-ultraviolet performance, the aging speed of the modified portland cement is slowed down, and the service life of the modified portland cement is prolonged; secondly, liquid CO2 is introduced in the process of preparing the concrete for fixing and sealing CO2, so that C3S and beta-C2S in the modified Portland cement can be respectively subjected to mineralization reaction with CO2, the concrete can be used for mineralizing and sealing CO2, the effect of fixing and sealing CO2 is achieved, through the operation, the environment can be improved and the emission amount of CO2 in the environment can be reduced in a CO2 fixing and sealing manner, and the environment can be protected. And the strength of the concrete can be improved through mineralization reaction.
本发明涉及混凝土生产工艺技术领域，提供一种固封CO2的混凝土预制墙板及其生产工艺，本发明中通过多巴胺对二氧化钛进行改性，能够使二氧化钛具有更高的黏附力，从而使改性后的二氧化钛将抗菌组分和抗紫外组分中的分子紧紧附着在硅酸盐水泥的表面上，使改性硅酸盐水泥具有较好的抗菌性能和抗紫外性能，从而减缓改性硅酸盐水泥的老化速度并延长其使用寿命；其次，在制备固封CO2的混凝土的过程中通入液态CO2，能够使改性硅酸盐水泥中的C3S和β‑C2S分别与CO2发生矿化反应，从而使混凝土对CO2进行矿化封存，达到固封CO2的作用，如此操作，既能够通过固封CO2的方式来改善环境，减少环境中CO2的排放量，又能够通过矿化反应提高混凝土的强度。
