Abstract

The invention provides a colorful facing baking-free brick, a double-component curing complexing agent and a preparation method of the multi-color facing baking-free brick, wherein the double-component curing complexing agent comprises an agent A and an agent B; the agent A comprises the following components: cement, slaked lime, water-borne epoxy resin, nano aluminum oxide and methyltriethoxysilane; and the agent B comprises the following components: potassium silicate, sodium methyl silicate, styrene-acrylic emulsion, isopropanol, sodium lignin sulfonate and aluminum potassium sulfate. The agent B is diluted by 1-2 times, the agent A is added, and uniform stirring is carried out to obtain the double-component curing complexing agent. Cement, iron oxide red and granules are mixed, water is added, the double-component curing complexing agent is sprayed and added while stirring is conducted, compression molding is conducted after stirring is conducted for 30-50 min, curing is conducted under the natural condition, and after drying is conducted, the multi-color facing baking-free brick is obtained. The A agent of the double-component curing complexing agent can be prepared on site, and the agent B is a high-concentration agent, so that the cost is saved, the efficiency is improved, the energy is saved, the environment is protected, and the requirements of carbon neutralization and carbon peak reaching are met.

Description

technical field [0001] The invention relates to the technical field of unburned bricks and their curing agents, in particular to a colorful veneered unburned brick, a two-component curing composite agent and a preparation method thereof. Background technique [0002] Construction waste such as dregs, mud, steel slag, and fly ash are spoils, waste materials, and other wastes generated during the construction process. These solid wastes have low utilization rates, serious pollution, high storage costs, and improper disposal. brought huge pollution. Therefore, the comprehensive utilization of construction waste is of great significance for saving resources, improving the environment, improving economic and social benefits, and realizing optimal allocation of resources and sustainable development. Contents of the invention [0003] In order to solve the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a kind of multi-color venee...
