Problems solved by technology

The aging resistance and pollution resistance of flexible facing bricks are difficult to meet the market requirements, and the fire performance cannot reach Class A; It is difficult to overcome the common problem of "pan-alkaline" in cement-based materials. Although some companies have developed several products to inhibit pan-alkaline, the price is expensive, and the effect is not particularly good in practical applications.

Abstract

The invention discloses a flexible decorative sheet and a manufacturing method thereof. The flexible decorative sheet disclosed by the invention is composed of the following raw materials by mass percent: 30-60% of blast furnace mineral powder, 7-20% of acrylic polymer emulsion, 0.1-2% of fibre, 0.1-5% of water repellent, 0-3% of pigment, and the balance of filling material. According to the invention, the use amounts of cement and polymer emulsion are greatly reduced, so that the cost is greatly reduced; and the flexible decorative sheet disclosed by the invention has the characteristics of being excellent in ageing-resistant performance, good in fireproof performance and saltpetering-resistant.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a flexible decorative sheet and a manufacturing method thereof. Background technique [0002] Due to the insurmountable potential safety hazards of ceramic bricks as exterior wall finishing materials, especially high-rise external wall external insulation system finishing materials, most areas in China currently restrict the use of ceramic bricks on exterior walls. Due to its light weight and certain flexibility, the flexible sheet is an ideal facing material for high-rise external thermal insulation systems. There are mainly three types of flexible decorative sheets that have been reported so far: flexible tiles made of real stone paint raw materials, flexible sheets made of clay, and cement-based flexible sheets. The aging resistance and pollution resistance of flexible facing bricks are difficult to meet the market requirements, and the fire performance cannot reach Class A;...
