Abstract

The invention discloses a permeable color-adjustable concrete protective material and a preparation method thereof, and relates to the technical field of concrete protection and decoration, the permeable color-adjustable concrete protective material comprises a bottom coating which directly coats the surface of concrete and a surface coating which coats the surface of the bottom coating, the bottom coating comprises the following raw materials by weight: 2-20 parts of a water soluble polymer, 10-30 parts of auxiliary infiltration emulsion, 5-10 parts of a silane compound, 20-40 parts of a filler, 2-8 parts of a pigment, 1-3 parts of an emulsifier, 35-60 parts of deionized water and 0-5 parts of a 1# assistant agent; the surface coating comprises the following raw materials by weight: 70-94 parts of fluorocarbon emulsion, 0-20 parts of deionized water and 6-20 parts of a 2# assistant agent; excellent adhesion exists between the bottom coating and a base material and between the bottom coating and the surface coating, due to double-layer protection, even the surface coating is locally damaged, the bottom coating also can play decorative and protective effect, and the permeable color-adjustable concrete protective material has the advantages of no toxicity, no pollution, no VOC emission and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of concrete protection and decoration, in particular to a permeable color-tunable concrete protection material and a preparation method thereof. Background technique [0002] Concrete is a complex, heterogeneous heterogeneous body, and the behavior of both cement slurry and concrete cannot be characterized by the simple superposition of the individual behaviors of its components. The cement concrete material is the same as most of the commonly used building materials. It is a typical porous material with different pore sizes and extremely complex pore structures, spanning the three scales of micro, meso and macro. Studies have shown that the pore structure of concrete It has an important influence on its strength, impermeability, deformation and many other macroscopic properties. [0003] my country is in a stage of rapid development, and a large number of infrastructure constructions are inseparable from c...
