Abstract

The invention belongs to the technical field of coatings, and in particular relates to a preparation method of a concrete interface agent. In the present invention, the rinsed peach gum is first heat-swelled and homogeneously treated, and after rotary evaporation, it is mixed with alumina and ball-milled to dry, and then heat-preserved and calcined to obtain a matrix material, and then paraffin wax, deionized water, etc. are mixed and heated, and then persulfuric acid is added Ammonium, methyl methacrylate, etc., heated in a water bath, filtered and dried to obtain a temperature-adjusting material, mixed with the base material and ball-milled to obtain a mixed modified powder, and finally mixed with silica fume, fly ash, mixed modified powder, etc. to obtain a concrete interface The concrete interface agent prepared by the invention has good freeze-thaw resistance, improves the waterproof performance of the concrete base, and has good durability.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a preparation method of a concrete interface agent. Background technique [0002] In recent years, as people pay more and more attention to the field of building energy conservation, related technologies in the field of building energy conservation have developed rapidly. At present, buildings usually adopt frame structure and frame-shear wall structure, and cast-in-place concrete occupies a large proportion in building construction, and the support formwork of cast-in-place concrete technology usually adopts steel formwork, wood formwork or bamboo glue board, etc. The construction process In addition to the complex process of formwork support and formwork removal, there are also problems such as easy deformation of pouring, large amount of formwork, and high engineering cost. At the same time, according to the relevant regulations on building energy conservation, t...
