A kind of water-based inorganic polymer slurry for colorful coatings and its preparation method and application

Abstract

The invention relates to waterborne inorganic polymer slurry for a colorful coating, and a preparation method and an application thereof. The slurry comprises the following components in parts by weight: 10-20 parts of water, 10-30 parts of an emulsion, 0.1-0.5 part of a wetting agent, 0.1-0.5 part of a defoaming agent, 1-2 parts of lignin fibers, 10-30 parts of quartz sand, 10-30 parts of Portland cement, and 10-30 parts of a flame retardant. During preparation, the water and the emulsion are mixed firstly, and then the wetting agent, the defoaming agent, the lignin fibers, the water reducing agent, a film-forming auxiliary agent, the Portland cement, the flame retardant and quartz sand are sequentially added under stirring; during application, the surface of a slurry template is sprayed with the colorful coating, then the slurry template is pasted on walls by the way of bonding mortar, and a stone-like thick sense is exhibited. Compared with the prior art, the waterborne inorganic polymer slurry is combined with the colorful coating to prepare a waterborne inorganic polymer colorful coating composite material, and the composite material can be rapidly pasted on the walls by the way of bonding mortar, can replace a dry-hanging stone material, has fire resistance and toughness, and has long service life.

[0002] Although natural granite, which is used as a decorative material for interior and exterior facades of buildings, is gorgeous in appearance, due to the depletion of natural stone resources, the damage to the natural environment caused by natural stone mining and environmental pollution, the natural color difference of stone source mines, dry hanging The safety and environmental protection of the stone are poor, and the stone as a rigid material cannot be applied to places requiring shapes such as arcs and Roman columns. Natural granite is gradually being replaced by water-based granite coatings, replacing natural granite in the form of coatings. The way of stone color effect has gradually become the mainstream

However, this method has many problems in the coating construction process.

Due to the wide range of professional knowledge involved in the coating construction technology, the requirements for the construction skills and level of the construction personnel are relatively high, so problems such as uneven spraying of the wall surface and color difference often occur during construction.

In addition, when coating is applied on the construction site, due to the influence of factors such as weather and construction environment, multiple construction procedures are required, and a lot of protection work is carried out to improve construction safety and increase construction costs.

But even so, most paint products still can't really have the thick feeling of stone
