High-performance and water-proof internal wallboard of building wall

Abstract

The invention discloses a high-performance and water-proof internal wallboard of a building wall. The internal wallboard is characterized by comprising a base layer, a bonding layer, a fire-proof layer, a water-proof layer, a latex layer and a decorative coating which are sequentially arranged from inside to outside, wherein the water-proof layer is made of an acrylic coating comprising raw materials in parts by weight as follows: 20-30 parts of terpene resin, 30-40 parts of butyl acetate, 15-25 parts of an acrylate copolymer emulsion, 10-20 parts of an acrylic acid solution, 0.5-1.5 parts of a water-proof agent, 20-30 parts of glass beads, 30-40 parts of a modified nanomaterial, 0.5-1.5 parts of titanium dioxide, 20-30 parts of gypsum, 5-10 parts of kaolin, 20-25 parts of diatomite, 1-3 parts of a dispersing agent, 0.5-0.8 parts of a leveling agent, 1.5-2.5 parts of an isothiazolinone derivative, 0.5-2 parts of fatty alcohol polyoxyethylene ether ammonium sulfate, 15-20 parts of propylene glycol butyl ether, 0.5-1.5 parts of an antioxidant, 1-2 parts of an organosilicon antifoaming agent and 1-2 parts of an ether-modified organosilicon antifoaming agent.

Description

technical field [0001] The invention relates to the technical field of wallboards, in particular to a high-performance water-resistant inner wallboard for building walls. Background technique [0002] Interior wall panels are used to protect and decorate building walls, so they must have good enough weather resistance, stain resistance and freeze-thaw resistance to ensure good decorative effects and durability. The interior wall panels can make the building walls clean and beautiful, so as to beautify the urban environment and protect the walls of buildings. However, the interior wall panels currently on the market have poor water and oil resistance and short service life, which affects the appearance of buildings. It also reduces the service life of the building wall. Contents of the invention [0003] The invention provides a high-performance water-resistant inner wallboard for building walls, which has good water resistance, good mechanical properties and extremely exc...
