Preparation method of aqueous colorful stone-like concrete product

Abstract

The invention relates to the field of construction materials for building roads, bridges, squares, residential districts, etc., and especially relates to a preparation method of an aqueous colorful stone-like concrete product. The preparation method comprises the following steps: (1) pre-processing the surface of a concrete matrix; (2) roll-painting an interface agent on the pre-processed surface of the concrete matrix; (3) after the interface agent is dried, painting an interface agent containing a modifier; (4) after the interface agent containing a modifier is dried, spraying an aqueous colorful paint; (6) at least 24 hours after colorful paint spraying, painting a finishing paint at first, and after the finishing paint is dried, painting a finishing paint containing a modifier. The prepared aqueous colorful stone-like concrete product has the advantages that the color of the appearance of the concrete product can last for a long time, the waterproof effect is good, the adhesion strength and dynamic anti-breaking performance are strong, and moreover, the method can be used to renew the old concrete buildings.

Description

technical field [0001] The invention relates to the field of building materials such as roads, bridges, squares and residential quarters, in particular to a method for preparing water-based colorful stone-like concrete products. Background technique [0002] Ordinary concrete products are simple concrete structures with gray and dark exterior colors and relatively single shapes. With the progress of society and the improvement of people's living standards, the requirements for urban development and beautification have also increased, and the requirements for the appearance of building materials such as curbs, barricade balls, railing posts and railing panels have also increased. Existing curb stone products of materials such as marble and granite have also come out thereupon, but the cost of curb stone products of pure granite is too high, which causes the cost to be too high when used in large quantities in urban construction, and is not easy to process. It meets the requi...

Problems solved by technology

However, due to the influence of man-made or weather, the color of the paint in the open air cannot be maintained for a long time, and it needs to be repainted frequently, and the problem of environmental pollution caused by paint construction has attracted widespread attention. The organic volatiles in the paint are the cause of air pollution. The main reason, especially the treatment of waste gas, waste water, and waste slag generated during paint construction on the construction site, has become the key protection object of the environmental protection department. This requires a lot of manpower, material and financial resources, and is not suitable for the energy-saving and environmental protection situation of modern society.

At present, the commonly used stone-like concrete products are high in cost, low in simulation, poor in appearance color durability, unsatisfactory in waterproof effect, low in bond strength and dynamic crack resistance, which affects the durability of stone-like concrete products and shortens their lifespan.
