Energy-efficient priming paint

Abstract

The invention belongs to constructional wall-facing material technical field, especially relating to energy-efficient priming paint which has decoration and thermal insulation effects to inner and exterior walls of a building. The energy-efficient priming paint of the invention comprises the following components by weight: 15%-25% of mixed emulsion, 1%-3% of film forming auxiliary agents, 5%-15% of silica sol, 0.1%-0.2% of antifoaming agents, 0.1-0.2% of mildew-resistant bactericides, 5%-20% of hollow glass beads, 10%-30% of heavy calcium carbonate and 0.2%-1.5% of thickening agents, and rest is water, wherein the hollow glass beads have a granularity range of is 10 microns-180 microns, a bulk density of 0.10-0.50g / cm<3> and a floating rate more than 90%. The energy-efficient priming paint in the invention has functions of waterproof and thermal insulation. Painting the paint on the inner and exterior walls of the building has a great meaning for maintaining indoor temperature and saving energy. The energy-efficient priming paint is especially suitable for matching usage with synthetic resin thick slurry paint and synthetic resin sand textured paint.

Description

technical field [0001] The invention belongs to the technical field of building wall materials, and in particular relates to an energy-saving primer for decorating and insulating the interior and exterior walls of buildings. Background technique [0002] Decorative mortar is a new type of wall decoration material imported from abroad in my country. It is composed of inorganic gelling materials, fillers and aggregates, and is used for decoration on the surface of building walls. Compared with traditional facing materials such as ceramic tiles and paints, decorative mortar has the rich color, shape and excellent durability of paint, and at the same time, the construction speed is fast, and the thickness of the decorative mortar is only 3-8mm, and the weight is light, which can be greatly improved. Reduce the load of the external thermal insulation system. When it is used as a high-rise building finish, it will not peel off due to negative wind pressure, thereby ensuring that t...
