Description

Finishing Mortar Exterior Wall Decorative Coating Structure

technical field

The utility model relates to the field of exterior wall decoration, in particular to an exterior wall decoration coating structure with facing mortar.

Background technique

With the improvement of living standards, people's requirements for the living environment are not limited to health, comfort, and beauty, but also put forward new requirements for exterior wall decoration that are close to nature, green and environmentally friendly, novel in shape, safe and reliable. The facing brick veneer is durable, with good durability and texture, bright colors and rich decorative effects, but it is heavy, poor in air permeability, easy to fall off, and has potential safety hazards. Organic decorative materials such as paint and real stone paint have poor long-term durability. After being exposed to wind, sun, and rain, aging, cracking, and water ingress may occur, and the maintenance costs in the later period will be high. Facing mortar is a kind of decorative material blended with inorganic gelling materials, optimized graded aggregates, building additives and pigments in a certain proportion. It has excellent performance, rich artistic expressions, simple and fast operation, and high safety. It can meet the requirements of modern building exterior wall decoration, but the facing mortar is greatly affected by the weather during construction. Under high temperature and dry weather conditions, it dries quickly and has a deep color. Under high humidity and low temperature conditions, it dries very slowly and loses color Shallow, resulting in obvious color difference and difficult to control; after the construction of the finishing mortar, the alkali or salt in the coating migrates with the water and deposits on the surface of the coating, which is easy to cause the problem of alkali return.

Utility model content

The main technical problem to be solved by the utility model is to provide a decorative coating structure of facing mortar and exterior wall, which has good durability, strong adhesion, is not easy to crack and has a strong texture, avoids alkali return, and improves the stain resistance of the coating structure. Pollution.

In order to solve the above technical problems, a technical solution adopted by the utility model is: provide a decorative coating structure of facing mortar exterior wall, the coating structure is the base layer on the exterior wall, and is provided with an anti-crack protection layer and putty in sequence from the inside to the outside layer, primer layer, inorganic finishing mortar decorative layer and topcoat layer.

In a preferred embodiment of the utility model, the anti-crack protection layer is a flexible anti-crack and waterproof mortar layer embedded with an alkali-resistant and anti-crack grid cloth.

In a preferred embodiment of the present invention, the putty layer is a moisture-proof and anti-crack putty layer.

In a preferred embodiment of the present invention, the top paint layer is a water-based silicone acrylic colored finish paint layer.

The beneficial effect of the utility model is that the anti-crack protective layer of the utility model adopts flexible anti-crack waterproof mortar supplemented with alkali-resistant and anti-crack grid cloth, which can resist the deformation of the base layer and avoid the water vapor on the base layer of the wall from affecting the bonding of the putty layer The decorative layer adopts facing mortar, and the facing mortar adopts different methods such as dragging, rolling, scraping, twisting, kneading, etc. , so that the wall changes into various patterns such as embossing, corrugation, wood grain, etc., forming a variety of textures and textures. It has a very obvious texture and a good main decorative effect, and the facing mortar has good durability and UV resistance. Strong durability, high bonding strength, waterproof and breathable, etc., provide durable protection for buildings; the topcoat layer is a water-based silicone acrylic colored finish paint layer, which can effectively solve the color difference caused by the construction of the facing mortar and prevent moisture from infiltrating into the finish Mortar layer, to avoid alkali return, and improve the stain resistance of the coating structure.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, the utility model embodiment comprises:

A decorative coating structure for a facing mortar exterior wall, the coating structure is the base layer 1 on the exterior wall, and is provided with an anti-crack protection layer 2, a putty layer 3, a primer layer 4, and an inorganic facing mortar decorative layer 5 in sequence from the inside to the outside and topcoat layer 6.

In the utility model, the anti-crack protective layer 2 is a flexible anti-crack and waterproof mortar layer embedded with an alkali-resistant and anti-crack grid cloth.

In the present utility model, the putty layer 3 is a moisture-proof and anti-crack putty layer.

In the present utility model, the top paint layer 6 is a water-based silicon acrylic colored finish paint layer.

The beneficial effect of the decorative coating structure of the exterior wall of the utility model is that the anti-crack protective layer 2 of the utility model adopts flexible anti-crack waterproof mortar and is supplemented with an alkali-resistant and anti-crack grid cloth, which can resist the deformation of the base layer and avoid the deformation of the wall surface. The water vapor on the base layer affects the adhesion of the putty layer; the decorative layer is made of facing mortar, which is dragged, rolled Different methods such as scraping, twisting, kneading, etc., make the wall surface change into various patterns such as embossing, corrugation, wood grain, etc., forming a variety of texture and texture effects, with very obvious texture and good main decoration effect, and Finishing mortar has the characteristics of good durability, strong UV resistance, high bonding strength, waterproof and breathable, etc., and can provide lasting protection for buildings; topcoat layer 6 is a water-based silicone acrylic colored finish paint layer, which can effectively solve the problem of facing mortar The color difference generated during construction can prevent moisture from infiltrating into the finishing mortar layer, avoid alkali return, and improve the stain resistance of the coating structure.

The above descriptions are only examples of the present utility model, and are not intended to limit the patent scope of the present utility model.
