Problems solved by technology

However, most of the current integrally colored concrete is a simple physical mixing of traditional concrete and pigments. Although it is integrally colored, most of the concrete and dyes are not well bonded. Exposure to the outside for a long time will lead to uneven dispersion of pigments and poor concrete strength. Insufficient cracking, late concrete fading and other problems

Embodiment

[0033] The preparation method of colored microcapsule concrete comprises the following steps:

[0034] Step 1: Process aggregates, cement, microcapsule composite dyes, polycarboxylate superplasticizers, fly ash, mineral powder and other components into required sizes and pre-homogenize them;

[0035] Step 2: Carry out continuous batching according to weight ratio;

[0036] Step 3: Put the prepared aggregate, cement, fly ash, mineral powder, etc. into the mixer and stir for 1-2 minutes;

[0037] Step 4: Add microcapsule composite dye and stir for 2-3 minutes;

[0038] Step 5: Add water and stir for 1-2 minutes;

[0039] Step 6: Finally, add polycarboxylate water reducer and stir for 2-3 minutes to obtain the colored microcapsule concrete.

[0040] The difference of each embodiment is only the mass parts of each component is different, and the mass parts of each component in Comparative Examples and Examples 1-4 are shown in Table 2 below.

Abstract

The invention discloses colored microcapsule concrete and a preparation method thereof. The concrete is prepared from the following components in parts by weight: 0-50 parts of aggregate, 100 parts ofcement, 10-50 parts of a composite dye, 0.5-5 parts of a water reducing agent and 0-50 parts of water, wherein the composite dye exists in a form of microcapsules, the microcapsules are prepared fromresin and pigment, and the weight of the pigment is 10-100% of that of the waterborne resin. The colored microcapsule concrete does not easily fade since the composite dye exists in the form of microcapsules while the concrete strength is improved, so that the overall durability of the colored microcapsule concrete is improved.

Description

technical field [0001] The invention relates to the technology in the field of building materials, in particular to a colored microcapsule concrete and a preparation method thereof. Background technique [0002] Traditional concrete floors and pavements are monotonous and boring in color. With the continuous application of new colored concrete materials in the construction field, people have colorful urban roads, bright industrial floors and dazzling architectural appearances, which is conducive to the coordination and unity of structures and the natural environment, and is conducive to further improving the overall quality of large buildings. Image design is of great significance. [0003] At present, there are three main ways to prepare colored concrete: surface coloring method (spraying or lamination), chemical dyeing method and overall coloring method. Both the surface coloring method and the chemical dyeing method are used to stain the surface of the concrete after it...
