Abstract

The invention relates to a preparation method of a fiber-modified cement-based waterproof material, and belongs to the technical field of waterproof material preparation. The preparation method of thefiber-modified cement-based waterproof material comprises the steps of: firstly using flax fiber as a raw material, removing lignin components in the fiber by immersing with an alkali solution, thenmixing the alkali-impregnated fiber and lemon juice and putting into a high-pressure cooking pot to be cooked and modified to obtain a modified fiber, then molding biological fat under conditions of high temperature and high humidity, mixing and fertilizing a mold material and an aluminum sulfate solution to obtain a self-made waterproof filler, finally, mixing the modified fiber with the self-made waterproof filler and other auxiliary materials, and thus finally obtaining the fiber-modified cement-based waterproof material. The fiber-modified cement-based waterproof material prepared by the method has good toughness, is not easy to crack, has excellent water resistance, and has broad application prospects.

Description

technical field [0001] The invention relates to a preparation method of a fiber-modified cement-based waterproof material, which belongs to the technical field of waterproof material preparation. Background technique [0002] The rapid development of the real estate industry has directly promoted the development of the construction industry, and a number of high-quality construction projects have emerged. Destruction is the most common, and the existence and migration of water are important reasons for destroying the performance of concrete and masonry structures, and the phenomena of efflorescence and mildew on the wall are related to the existence and migration of water. The leakage problem has greatly shortened the service life of many buildings and caused a great waste of social resources. The main reason for the leakage of concrete structures is the structural defects of internal pores and micro-cracks. To solve this problem, not only to improve its own compactness, bu...
