Problems solved by technology

[0002] A large amount of construction mortar is required in the construction process of the building. Construction mortar is usually mixed with powder and liquid materials. Due to the large amount of construction mortar used in construction, the preparation of construction mortar and the transportation of its powder and liquid materials All bring some difficulties to the construction
Moreover, when buildings are abolished, a large amount of construction waste will be generated. The disposal of these construction wastes is difficult, time-consuming, and consumes a lot of manpower and material resources.
[0003] A large amount of construction waste contains a large amount of recyclable resources, such as metal, wood, plastic and cement paste. These resources are treated as garbage, which not only makes post-processing difficult, but also wastes resources.

Embodiment 1

[0020] A kind of application construction waste that the present invention proposes prepares the method for construction mortar, comprises the following steps:

[0021] S1: Crush the construction waste into fine materials, separate metal, wood and plastic through an intelligent screening machine, and recycle metal, recycle wood and recycle plastic, and put the remaining fine materials and water at a solid-liquid ratio of 1:40. Mix in a kneader, stir at high speed for 20 minutes, filter through a mesh sieve, collect the filtrate, which is the base material liquid;

[0022] S2: Heat and melt the epoxy resin and the recycled plastic separated in step S1 at 60°C at the same time to obtain a resin mixture for later use;

[0023] S3: Add cement to the above-mentioned basic material liquid, and mix well to obtain the mixed liquid A, then turn on the heating switch of the mixer to make the temperature of the mixer reach 60°C, and then add the resin mixture prepared in S2 to the mixing...

Abstract

The invention discloses a method for preparing building mortar by using building wastes. The method comprises the following steps of S1, crushing the building wastes, separating metals, woods and plastics, and mixing the left fine aggregate and water, so as to obtain a basic material liquid; S2, melting epoxy resin and recycled plastics, so as to obtain a resin mixed liquid; S3, adding cement into the basic material liquid, so as to obtain a mixed liquid A; adding the resin mixed liquid into the mixed liquid A, and then adding an adhesive, diethyl phthalate, a coloring agent, an anti-precipitating agent and a flame-retardant agent, so as to obtain a mixed liquid B; S4, dispersing silicate powder into the mixed liquid B, and adding a curing agent, so as to obtain the building mortar. The method for preparing the building mortar has the advantages that the building wastes can be recycled and reutilized, so that the problem of difficulty in treatment of the building wastes is solved, and the production cost of the building mortar is reduced; the prepared building mortar has excellent property, high strength, good peaceability, strong adhering force, and good waterproof and flame-retardant properties.
