Problems solved by technology

[0003] 1. The flexible decorative brick with polymer cement sheet as the base, the substrate is made of polymer cement and non-woven fabric, the surface material is made of high molecular polymer as gel material and sand and gravel as aggregate ;Due to the different composition of the bottom and surface materials, the difference in surface tension between the two materials after forming will cause the brick body to bend and deform to one side. Warping, resulting in the brick joints are not dense, and the brick joints are easy to enter water, causing engineering hidden dangers
[0004] 2. The overall flexible facing brick is compounded with high molecular polymer as the gel material and sand and gravel as the aggregate. Although it overcomes the shortcomings of structural deformation, the mechanical strength of the brick body is poor due to the absence of reinforced tire base, and the manufacturing The process adopts the lining mold, so that there are a large number of irregular pores on the bottom of the brick body, which reduces the structural strength
[0005] 3. The overall flexible facing brick is compounded with high molecular polymer as the gel material and soil as the aggregate. The structure of this kind of flexible facing brick is not deformed, and the mechanical strength is also good. However, the natural soil is limited by the monotonous color. The color paste is artificially dyed, so this kind of flexible facing brick is used for exterior walls, and its color is easy to age and fade
[0006] 4. The above three types of flexible facing bricks are divided into front and back sides. During construction, it is necessary to find the opposite side to paste, especially when pasting two colors of bricks, it is necessary to match two colors of flexible facing bricks, which will bring new advantages to the construction operation. inconvenient
[0007] 5. The gel materials of the current flexible facing bricks are all made of acrylic or styrene-acrylic modified polymer emulsions, which are subject to certain restrictions in terms of weather resistance and water vapor permeability

Abstract

The invention discloses a method for manufacturing a silicone modified double-sided double-color flexible decorative brick. The double-sided double-color flexible decorative brick is composited by three layers, the middle layer is a glass fiber reinforced layer (2), and a silicone modified polymer color sand A paste layer (1) and a silicone modified polymer color sand B paste layer (3) are respectively coated on the upper surface and the lower surface of the glass fiber reinforced layer, wherein the thicknesses of the coating layers of the A paste and the B paste can be controlled according to design requirements, and the colors of the A paste and the B paste can be the same or different according to design requirements. The double-sided double-color flexible decorative brick produced by adopting the manufacturing method of the invention has the advantages of good flexibility, light weight per unit area, no radioactive contamination, realistic stone-like and pottery-like patterns on the appearance, high manufacturing efficiency, energy saving and environmental protection without high-temperature sintering, weather resistance, wear resistance, vapor permeability, fire resistance, convenience of use and like.

Description

technical field [0001] The invention relates to a facing material for building walls or floors and a manufacturing method thereof, in particular to a manufacturing method of silica gel-modified double-sided and double-color flexible facing bricks. Background technique [0002] It will be an inevitable trend to use non-sintered flexible facing bricks instead of high-temperature sintered, high-energy consumption, and high-carbon-emission ceramic facing bricks as facing materials for the interior and exterior walls of buildings or indoor floors. In recent years, the flexible facing materials that have been introduced to the market successively have come out continuously, which has enriched the application market of building exterior wall facing materials. However, currently several representative flexible facing bricks have unsatisfactory places in practical applications, and the common defects are: [0003] 1. The flexible decorative brick with polymer cement sheet as the bas...
