Fireproof thermal insulation concrete wallboard and preparation method thereof
The invention relates to the technical field of concrete, in particular to a fireproof thermal insulation concrete wallboard and a preparation method thereof. The low-viscosity branched epoxy resin is firstly prepared, the dispersion performance of the low-viscosity branched epoxy resin in concrete is improved by utilizing the sphere-like structure of the low-viscosity branched epoxy resin, tiny pores in a concrete wallboard are filled by utilizing the film-forming property of the low-viscosity branched epoxy resin, the water absorption of the low-viscosity branched epoxy resin is reduced, the impact resistance of the wallboard is improved, and surface cracking and stripping are prevented; afterwards, a foaming agent and a foam stabilizer are further compounded, so that closed-cell bubbles in the concrete wallboard are increased, and the heat insulation and heat preservation performance of the concrete wallboard is improved. The concrete wallboard prepared by the invention has good fireproof and heat-insulating capabilities, strong impact resistance and stripping resistance, and excellent use performance.
本发明涉及混凝土技术领域，具体为一种防火保温混凝土墙板及其制备方法；本发明首先制备了低粘度支化环氧树脂，利用其类球形结构提升在混凝土中的分散性能，并利用其自身成膜性，填充混凝土墙板中的微小孔隙，减少其吸水性，并提高墙板抗冲击性能，防止表面开裂与剥离；之后本申请进一步地使用发泡剂与稳泡剂复配，使混凝土墙板中的闭孔气泡增多，提升其隔热保温性能。本申请制备的混凝土墙板具有良好的防火保温能力，抗冲击、耐剥落能力强，具有优异的使用性能。
