Method for manufacturing composite marble-imitated coating based on elastic multicolor paint

Abstract

The invention relates to a method for manufacturing a composite marble-imitated coating based on elastic multicolor paint, which comprises the following steps: a, forming a putty layer on a wall body,and applying an alkali-penetration-resistant primer by roll coating to form an alkali-penetration-resistant primer layer; b, spraying middle coating paint once to form a middle coating layer; c, after drying, applying an elastic multicolor paint by spray coating or roll coating to form a multicolor layer; and d, applying varnish once or multiple times by brushing or roll coating to form a finishing layer, wherein the multicolor layer is used as a marble-imitated main color layer, and the elastic multicolor paint comprises the following components in parts by weight: 50 parts of a pigment component, 20 parts of a dispersion medium and 30 parts of varnish. The elastic multicolor paint is adopted to form marble texture and marble veins, so that the service life of a building is prolonged while the decorative effect of the building is achieved. Meanwhile, the elastic multicolor paint has elasticity at normal temperature through emulsion type selection and an emulsion blending modificationtechnology, and the risks of cracking and peeling of the outer wall can be reduced.

Description

technical field [0001] The invention relates to a method for preparing a stone-like coating, in particular to a method for making a composite marble-like coating based on an elastic colorful paint. Background technique [0002] Real stone paint is a kind of paint for decorating exterior walls, and its decorative effect is similar to marble and granite. The buildings decorated with real stone paint have natural and real natural color. [0003] Real stone paint is mainly made of high molecular polymer, natural colored stone sand and related additives. After drying and curing, it is as hard as stone and looks like natural real stone. Therefore, it is now widely used in the construction industry. [0004] Real stone paint, according to the physical properties of the surface of the object to be constructed, is divided into two types: real stone paint on sand surface and real stone paint on rock surface. [0005] Although real stone paint has many advantages, but at the same tim...

Problems solved by technology

[0013] At present, the water-in-water multi-color coating products on the market are mixed, and in the existing technical solutions, this type of coating is mainly rigid, and only pays attention to the appearance effect (smooth, light and thin, etc.) and engineering cost while ignoring the overall weather resistance and The ability to resist damage from natural factors makes the coating product less flexible and elastic

In addition, the putty used for building exteriors is uneven, and the performance of the paint film of the exterior facade coating layer is too poor. Some paints even have the phenomenon of efflorescence on the wall soon after being applied. With the passage of years of use, the paint film on the wall It is easy to crack and fade, which will eventually affect the stability of the building structure, cause water seepage and dampness in the house, and increase safety hazards
