Preparation method of high-compression-resistance durable waterproof mortar
The invention belongs to the technical field of building material preparation, and particularly relates to a preparation method of high-compression-resistance durable waterproof mortar. The preparation method comprises the steps: firstly, crushing and mixing castor-oil plants and crop straws; and mixing, stirring and discharging a modified binder, ash cement, quartz sand and other assistants to obtain the high-compression-resistance durable waterproof mortar. The castor-oil plants and the straws are crushed and then subjected to a reaction with hydrochloric acid and a sodium hydroxide solutionat high temperature, the fiber components are increased, and the contact degree of the fiber components with other components is improved; hydrogen peroxide and sodium persulfate are used for oxidation treatment, ester groups are used for increasing the bonding effect between the fiber components and other components, the compressive strength of the waterproof mortar is improved, and the crackingphenomenon is inhibited; and meanwhile, the ester groups are coated with the fiber components, so that the waterproof performance and the impermeability of the waterproof mortar are improved; the fiber components are dispersed in the waterproof mortar, so that the compressive strength of the waterproof mortar is enhanced, contact oxidative decomposition with the external environment is avoided, the durability of the waterproof mortar is enhanced, and the application prospect is wide.
本发明属于建材制备技术领域，具体涉及一种高抗压耐久型防水砂浆的制备方法。本发明首先将蓖麻与农作物秸秆粉碎混合，将改性粘结剂、灰水泥、石英砂等助剂混合搅拌出料即得高抗压耐久型防水砂浆，本发明将蓖麻与秸秆粉碎先后与盐酸和氢氧化钠溶液高温反应，增加纤维成分，提高与其接触程度，再利用双氧水、过硫酸钠进行氧化处理，利用酯基基团增加纤维成分与其它成分之间的粘结作用，提高防水砂浆的抗压强度，抑制开裂现象，同时酯基通过纤维成分包覆提高防水砂浆的防水性能以及防渗透性能；利用纤维成分分散于防水砂浆中，增强防水砂浆的抗压强度，避免与外界环境接触氧化分解，增强防水砂浆的耐久性能，具有广阔的应用前景。
