Its shortcoming is that the mixing process is relatively complicated, and it cannot ensure that plant fibers or plant shavings are evenly mixed into cement or modified cement, so that the effect of reducing heat transfer and increasing toughness of plant fibers or plant shavings cannot be well achieved. reflect
[0003] As a building exterior wall decoration and enclosure material, natural stone has the advantages of beauty and durability, but its density is high and heavy, and it is dangerous when applied to high-rise building exterior walls; and the mining of natural stone also causes great pollution to the environment and waste of resources and energy

Embodiment 1
[0030] see figure 1 , an exterior wall decorative hanging board provided by the present invention, comprising a decorative layer 1 and a structural layer 2, the structural layer 2 is a colored stone concrete layer, colored concrete or cement mortar layer, and its interior is filled with a 3D structure alkali-resistant glass fiber mesh 3.
[0031] For the decorative layer 1, in order to better adhere and combine with the structural layer 2 (plate), and to withstand the influence of the external environment, the coating with strong weather resistance and good corrosion resistance should be selected. It is currently used in the market for exterior Fluorocarbon coatings and water-based environmentally friendly elastic coatings have excellent performance in the decorative surface of wall coatings, and before the finishing layer is painted, the surface of the structural layer 2 should be infiltrated with a primer, so that the structural layer 2 (plate) can be compatible with The fi...
Embodiment 2
[0035] Present embodiment is the production process of the present invention:
[0036] (1) Prepare raw materials: cement 25-40kg, river sand 10-30kg, fly ash 5-15kg, waste molding sand 0-20kg, stone scrap 0-25kg, early strength water reducer 0.2-0.5kg, hydrophobic Agent 0.02-0.04kg, alkali inhibitor 0.01-0.03kg;
[0037] Waste molding sand is the solid waste generated in the production process of the wear-resistant casting industry, which is a mixture of granular and powdery, and the sieve residue after passing through a 2.50mm sieve is ≤8%;
[0038] The fineness modulus of river sand is 1.5-2.6, and the mud content is less than 3%;
[0039] Stone leftovers are discarded leftovers after crushing in the quarry and leftovers after the stone is cut into finished products by the stone processing plant. The maximum particle size is ≤5mm. Since the stone includes a variety of colors, colored stone concrete will be produced during processing and manufacturing. layer, colored concre...

Abstract
The invention discloses a manufacturing process for an external wall decoration hanging plate. The manufacturing process comprises the step of manufacturing a structure layer. The main raw material of the structure layer comprises coal ash, industrial wastes such as wear-resisting industrial waste molding sand, broken quarry scraps and colored quarry processing factory corner wastes. The manufactured structure layer is a color stone concrete layer or a color concrete layer or a cement mortar layer. The structure layer is filled with a 3D-structure alkali-resisting glass fiber mesh which comprises net-like alkali-resisting glass fiber cloth of the top face and the bottom face of a heat-preserving layer. Alkali-resisting glass fiber filaments arranged in the structure layer in a penetrating mode are uniformly distributed between the two pieces of the net-like alkali-resisting glass fiber cloth. Utilizing waste resources for producing the external wall decoration hanging plate, the manufacturing process has the advantage of low cost. In addition, the 3D-structure alkali-resisting glass fiber mesh is embedded into the structure layer, the related requirements of traditional external wall cladding can be met, and the strength and the shock-resistant, cracking-resistant and waterproof abilities are improved.
Description
technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a manufacturing process of an exterior wall decorative hanging board. Background technique [0002] Existing external wall hanging boards, as the decoration and protective layer of buildings, are mainly composed of stone and cement composite materials, such as cement particle boards and cement fiberboards, and cement composites mainly use cement or modified cement (such as foamed cement) etc.) are mixed with plant fibers or plant shavings to form. Its shortcoming is that the mixing process is relatively complicated, and it cannot ensure that plant fibers or plant shavings are evenly mixed into cement or modified cement, so that the effect of reducing heat transfer and increasing toughness of plant fibers or plant shavings cannot be well achieved. reflect. [0003] As a building exterior wall decoration and enclosure material, natural stone has the advanta...
