Abstract

The invention discloses a polymer modified binding material of sulphate aluminum cement base. The polymer modified binding material of sulphate aluminum cement base is prepared from, by weight, 750-850 parts of modified cement, 900-1350 parts of quartz sand, 100-120 parts of mineral admixture, 5-8 parts of modified polymer gelatine powder, 2-4 parts of retarder, 4.5-9 parts of water reducing agent, 0.05-0.1 part of defoaming agent; the allowance is water. Meanwhile, the invention further discloses a preparation method of the polymer modified binding material, which includes steps of weighting raw materials at ratio, adding water to stir, and preparing to be slurry, and others. The binding material prepared by the invention can improve the binding ability between interfaces by modifying a polymer; the binding material is high in binding strength and good in flowability; the novel polymer modified binding material with good economic benefit and social benefit has advantages of preventing flash setting and fully saving material and cost.

Description

technical field [0001] The invention belongs to the technical field of bonding materials, in particular to a bonding material modified with polymers to modify sulphoaluminate cement. Background technique [0002] In recent years, with the development of prefabricated concrete structures in China, new requirements have been put forward for interface connection technology. No matter in the process of repairing, strengthening or bonding external wall insulation materials or ceramic tiles, it is necessary to consider the bonding performance of the interface of the construction materials used. Therefore, it is of great significance to improve the interface bonding performance of materials. Because polymers have good cohesive force and higher tensile strength compared with inorganic non-metallic materials, polymers are often used to modify cement materials to improve the bonding performance and tensile properties of cement materials. The most common It is the application of d...
