Problems solved by technology

However, the existing technologies (see Chinese patent publications 200810026831.0, 201010225614.1, and 201010225624.5) mainly focus on improving the expressiveness of the product, and the product itself has no thermal insulation function. In the actual construction process, it is often used with polystyrene, polyurethane and other thermal insulation boards. Not only is the construction process complicated, but also due to the rigidity of the insulation board, the advantages of soft porcelain flexibility are difficult to reflect
In addition, the introduction of a large number of organic thermal insulation materials has increased the fire safety hazards of buildings, which also greatly limits the application of soft porcelain and other decorative materials

Embodiment 1

[0036] Kaolin 25%, fly ash floating beads 19%, flexible emulsion 30%, acrylic acid 2.9%, defoamer 3%, 2-hydroxy-4-methoxybenzophenone 0.1%, water 14% ingredients by mass Afterwards, uniformly mix at a speed of 1000 r / min in a high-speed disperser to obtain a slurry with a viscosity of 8 Pa.s. In a gradient temperature-controlled oven, the slurry is repeatedly coated on the polyethylene template printed with decorative patterns, the thickness of each layer is 0.5mm, and after each layer is coated, an appropriate amount of glass fiber with a diameter of 2μm and a length of 3mm is evenly sprinkled After drying, the next layer can be applied. The total amount of fiber used is 6% of the mass of the slurry. The initial temperature of the oven is 90°C. For each increase in sample thickness by 1mm, the temperature rises by 10°C until the thickness reaches 3mm, and then rises to Keep warm at 170°C for 2 hours, then release the mold and trim the edges to obtain a light gray flame-retard...

Abstract

The invention discloses an inflaming-retarding flexible heat preservation facing material in building and a preparing method thereof, which is prepared from the following components in part by weight: 1-50 parts of soil particles, 1-50 parts of hollow filler, 1-10 parts of reinforced fibers, 10-50 parts of flexible emulsion, 0-1 part of pigment, 1-10 parts of accessory ingredient and 10-40 parts of water, that are mixed to form slurry with appropriate viscosity, are formed in a template with decorative patterns, so as to prepare a composite material with functions of inflaming retarding, heat preservation and decoration after gradient temperature control, drying and demoulding. According to the invention, the production process is environmental-friendly, the construction process is simple, convenient and feasible, and the inflaming-retarding flexible heat preservation facing material in building is particularly suitable for external facing of high-rise buildings and old town transformation.

Description

technical field [0001] The invention relates to the field of building thermal insulation and decoration materials, in particular to a flame-retardant flexible decorative material for external thermal insulation of building exterior walls and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, the number of high-rise buildings is increasing, the height is getting higher and higher, and the style is more novel and unique, which puts forward higher and higher requirements for building decoration materials. Traditional ceramic facing bricks are mainly made by high-temperature sintering, which not only has high production costs and high energy consumption, but also has disadvantages such as large specific gravity, non-deformable, poor air permeability, and high-altitude safety hazards, which can no longer meet the requirements of modern architectural decoration. Although exterior wall coatings have rich colors and strong decorative p...
