Bonded type coating board for outer wall and manufacturing method thereof

Abstract

The invention relates to a bonded type coating board for an outer wall and a manufacturing method thereof. The invention aims at providing the coating board which is light and thin and can be directly bonded on the outer wall of a building for construction. The method has the characteristic of convenience in manufacture. The technical scheme is as follows: the bonded type coating board comprises a mold plate and a coating layer positioned on the surface of the mold plate. The bonded type coating board is characterized in that the mold plate consists of glass-fiber gridding cloth and a bonding material filling the glass-fiber gridding cloth. The bonding material comprises the following components in parts by weight: (1) component A: cement, EVA latex powder, lignocellulose and hydroxypropyl methyl cellulose; filling aggregate; (2) component B: acrylic acid waterproof emulsion. The manufacturing method is carried out by the following steps of (1) preparing materials; (2) manufacturing into the mold plate; (3) curing and drying; (4) coating the formed mold plate with primer; (5) coating coatings in coating; (6) spraying the coatings; (7) spraying finishing paint; and (8) cutting into blocks and laminating films for protection.

Description

Technical field [0001] The invention relates to a paint board for exterior wall decoration and a manufacturing method of the paint board. Background technique [0002] Traditional exterior wall decoration materials include stone, ceramic tiles, paint and so on. The stone generally adopts the dry hanging method. The facing stone is directly hung on the wall or on the steel frame through metal pendants without grouting and pasting. The ceramic tile is generally pasted, but it is easier to fall off. The use of ceramic tiles is expressly prohibited in high-rise buildings; the coating decoration method is generally to directly apply directly on the outer wall of the building. Starting from the basic treatment, multiple processes are completed in sequence, the process is complicated, the labor is heavy, and the construction quality is not easy to control.

AI Technical Summary

Problems solved by technology

The stone generally adopts the method of dry hanging, and the facing stone is directly hung on the wall or empty on the steel frame through the metal pendant, without grouting and pasting; the ceramic tile is generally pasted, but because it is relatively easy to fall off, the national The use of ceramic tiles has been expressly prohibited in high-rise buildings; the paint decoration method is generally to directly paint on the exterior wall of the building, starting from the grassroots treatment, and completing multiple processes in sequence, the process is complicated, the labor load is large, and the construction quality is not easy to control

[0003] Chinese patent application document (application number 201410153371.3) discloses a decorative hanging board for exterior walls, the hanging board includes a structural layer and a decorative layer on the surface of the structural layer; the structural layer is colored stone concrete filled with alkali-resistant glass fiber mesh layer, colored concrete or cement mortar layer; the method of dry hanging is used for installation, which solves the problem of unstable paint construction quality

However, the keel needs to be installed in the dry hanging method, which is easy to damage the wall insulation layer and form a hot and cold bridge, which affects the quality of the project; moreover, the decorative hanging panels are all made of hard materials, which are fragile and easy to crack, posing safety hazards; in addition, the construction technology The requirements are high, so the construction cost is high, the construction period is long, and the economic benefits of construction enterprises are not high
