Problems solved by technology

At present, the most widely used outdoor decorative panels are: exterior wall coatings, exterior wall coatings are more economical, the advantages are stain resistance, old age resistance, simple and convenient construction and maintenance, but with the extension of use time, the coatings will peel off and fade. And it does not have the effect of heat preservation, and the decoration effect is poor
For ceramics and stone, the exterior bricks are durable, bright in color, excellent in decorative effect, easy to clean, fireproof and waterproof, wear-resistant and corrosion-resistant, but the cost is high and the construction is complicated. Due to the heavy weight of this kind of material, it is not suitable for larger High-rise building exterior walls use
Metal decorative panels, metal decorative panels include metal finishes and imitation metal exterior wall decorative panels. The construction of this type of exterior wall decorative panels is simple and easy to maintain, but the price is expensive.
Organic decorative board, this kind of board has good decorative effect, light weight, simple construction and cheap price, but the aging resistance effect is poor, and the use time is extended at any time, cracks and fading appear on the surface
Our team has published a soft-packed lightweight external-hanging decorative board and its preparation method (CN105802170A). The decorative board prepared by this invention patent has a better decorative effect, but the combination with the wall is poor, and it does not have thermal insulation effect. Grade B

Embodiment 1

[0026] Weigh the surface layer raw materials according to the proportion, and the mass ratio is composed of 55% quartz sand, 0.2% bakelite powder, 18% high aluminate cement, 18% emulsion and 8.8% water; the weighed raw materials Mix evenly to form a slurry and pour it into a glass plate mold on which the transfer film is laid, with a thickness of 5 mm. Spread a layer of grid cloth on the evenly spread slurry. Weigh various bottom raw materials, according to the mass ratio of 60% high aluminate cement, 10% light sand, 18% bakelite powder and 12% water, mix the weighed raw materials evenly to form a slurry , poured onto the grid cloth to a thickness of 5 mm. Put the above product into an oven at 70°C for 2 hours, take it out after cooling, and remove the protective film of the transfer film to obtain the finished product.

Abstract

The invention belongs to the field of building materials, and particularly relates to a novel light external decoration plate and a preparation method thereof. Inorganic adhesive materials of a bottom layer and organic silicone emulsion of a surface layer are compounded, cured and formed to obtain the novel light external decoration plate. Compared with a traditional external wall decoration material, the light decoration plate prepared by the method has good toughness and excellent popularization and application values, cannot burn and is small in density, light in dead weight and good in decoration effect, and environmental loads and the manufacturing cost of the plate are reduced by the aid of a lot of industrial waste.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a light-weight externally hung decorative board and a preparation method thereof. Background technique [0002] Exterior wall decorative board is a new type of building exterior wall decoration and thermal insulation integrated material developed in recent years. It is mainly used in exterior wall decoration and energy-saving renovation of various buildings such as residences, gymnasiums, libraries, school and hospital office buildings, villas, etc.; The main functions are architectural decoration, heat preservation and energy saving, heat insulation and sound insulation, waterproof and mildew proof. At present, the most widely used outdoor decorative panels are: exterior wall coatings, exterior wall coatings are more economical, the advantages are stain resistance, old age resistance, simple and convenient construction and maintenance, but with the extension of use time, the co...
