Method for making pattern on concrete surface

Abstract

The invention relates to a method for making a pattern on the surface of concrete. The method comprises the steps that a special printing medium is made; functional ink is made; the functional ink is printed on the special printing medium according to a certain pattern; the printed special printing medium is placed on a die table and a die, and the surface with the pattern faces the concrete pouring direction; the concrete is poured on the special-printing-medium surface with the pattern, and solidification is awaited; and the special printing medium is torn down. According to the method for making the pattern on the surface of the concrete, compared with negative-phase slow-setting imaging, the textured pattern is not formed on the concrete surface through concave-convex contrast, instead, the pattern is formed through direct permeating, the making difficulty is also reduced, a finer pattern and even a color pattern is presented, so that the surface of a building is more diversified, attractive and elegant; compared with positive-phase slow-setting imaging, the method for making the pattern on the surface of the concrete has all the mentioned advantages; compared with a water transfer printing technology, a large-size surface-imaged component can be made without the need of adding new equipment, while the large-size surface-imaged component cannot be made through the water transfer printing technology under the condition that the new equipment is not added, in addition, the water transfer printing technology is poor in outdoor application durability, and can result in the phenomena that colors become shallow and fall off, and the method cannot result in the phenomena that the colors become shallow and fall off.

Description

technical field [0001] The invention relates to a method for making patterns on the surface, in particular to a method for making patterns on the surface of concrete (including pouring products such as gypsum and magnesite). Background technique [0002] At present, there are several ways to make patterns on the concrete surface in the market. Negative phase retardation imaging, using the retarder to print the medium and the surface of the concrete through printing technology. The retarder makes the concrete surface solidify differently, and rinse with a high-pressure water gun. , forming a concrete surface with a concave-convex pattern. It is made of positive-phase retarded concrete with exposed aggregate, and the retarder is applied after covering. The covered part has no retarder and the uncovered part is sprayed with retarder. After a certain period of time, the part with retarder is washed with a high-pressure water gun to form a concave-convex contrast. pattern. Conc...

Problems solved by technology

[0003] The above-mentioned methods have the following defects: retarding time is affected by factors such as material temperature and humidity, and it is difficult to control the washing time; limited by display resolution, the minimum resolution is 3MM, there is a concave-convex texture, the concrete cannot achieve fine patterns, and the patterns are not easy to be too small; color Relatively simple; need a lot of water to wash, wasting resources; can only express the rough pattern of the silhouette, the fineness is worse; can not restore fine color patterns, the pattern is easy to deform; the operation is unstable, and large equipment needs to be used to place the components in the water; waste Resources; especially large components, not suitable for operation; the concrete surface needs to be treated before water transfer printing can be carried out; only oily ink can be used for activation, and a large amount of VOC is released during the use of activator; it will cause certain pollution to the environment
