Problems solved by technology

[0005] The technical problem mainly solved by the present invention is that the mechanical properties of the current polymer composite waterproof mortar are worse than that of the traditional cement mortar, so it is necessary to improve the mechanical properties of the polymer mortar by adding inorganic fillers, but the gap between the inorganic fillers and the polymer The poor compatibility of the mortar will lead to a large number of small cracks inside and on the surface of the mortar, the resistance will drop when the water passes through, and the water will easily seep, resulting in the defect that the impermeability strength will decrease. A preparation method for polymer composite waterproof mortar is provided.

Abstract

The invention relates to the technical field of building mortar preparations, and concretely relates to a preparation method of a polymer composite water-proof mortar. The preparation method of the polymer composite water-proof mortar comprises the following steps: firstly, natural river sand and glass fiber are used as filling materials to improve the mechanical properties of the mortar, orange peel juice and rose essential oil are decomposed to produce a large number of lipophilic ester groups and aromatic hydrocarbon groups under the function of microbes, and the lipophilic groups are introduced onto the surface of a mixed powder through microbes, so that the compatibility of an inorganic mixed powder with a polymer is improved, and the anti-permeable strength of the mortar is improved.According to the polymer composite water-proof mortar, the excellent water-resistant properties of silica sol and organic siloxane are fully used to improve the water-proof property of the mortar, besides the polymeric matrix contains abundant silicon hydroxyl groups, and the silicon hydroxyl groups and silicon hydroxyl groups on the surface of the modified mixed powder undergo a reaction under the effect of a heating power to form Si-O-Si bonds with extreme big bond energy, so as to improve the internal bonding strength of the mortar, and further improve the mechanical properties of the water-proof mortar, thereby, the polymer composite water-proof mortar has a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of building mortar preparation, in particular to a preparation method of polymer composite waterproof mortar. Background technique [0002] Leakage in construction projects has long been a difficult problem in the construction industry. The research on waterproof technology and waterproof materials has always been an important topic for researchers to study and solve. Polymer modified cement waterproof mortar is based on the traditional rigid cement mortar, by adding polymer components, using the reasonable combination of inorganic and organic materials, adjusting the internal structure of the hydration hardened body, to improve the mechanical properties of the material, waterproof and The purpose of adhesive performance. Common modified polymers include polyvinyl acetate-vinyl ester (EVA), polyacrylate (PAE), styrene-acrylic (SAE), etc. Among them, the traditional styrene-acrylic emulsion can improve the ...
