Description
Technical Field
The invention relates to a light stone-like heat-insulation veneer.
Background
The building outer wall heat insulation system is an important part in energy-saving buildings and is widely applied to domestic and foreign building engineering, and the existing heat insulation plates mainly comprise EPS plates, XPS plates, PU plates, phenolic aldehyde plates, foam concrete plates, rock wool plates and the like. The facing layer is inorganic plate, metal plate, stone plate, ceramic plate, etc. with various kinds of coating. The facing is directly bonded on the heat-insulating layer material by adopting polyurethane glue or epoxy glue. Such materials suffer from the following major disadvantages:
1. the veneer is not a light material, has large volume weight and cannot achieve light weight.
2. The heat-insulating layer is made of organic materials, so that the problems of poor durability and poor fireproof performance exist. The adopted inorganic heat-insulating material has the problems of high water absorption rate, large shrinkage rate, low strength, short service life and the like.
3. The volume weight difference between the veneer and the heat-insulating layer material is dozens of times, and the strength difference is dozens of times, so that the external wall heat-insulating system with heavy external weight, light internal weight, strong external force and weak internal force is formed. Although adhesive anchor bonding is generally used, the anchor must be anchored to the facing plate, so the supporting structure system and the construction process are very complicated.
In addition, the currently and generally adopted heat insulation mortar external wall heat insulation system has 4 problems:
1. the system has short durability, the design service life of the external thermal insulation engineering of the external wall is 25 years, whether the common organic thermal insulation material can be used for 25 years is still examined, and the inorganic thermal insulation has high water absorption rate and large shrinkage rate, which affects the actual service life.
2. Safety performance is worried about, the most common external wall thermal insulation material is still an organic material at present, the fireproof performance is poor, and fireproof potential safety hazards exist in the construction and use processes.
3. The construction process is complex, the quality hidden danger is many, the external thermal insulation technology of outer wall has very strict requirements on the construction level, if the construction method is not familiar with the technical requirements, or the technical operation level of workers is low, the construction management is not strict enough, and serious quality problems are easy to generate.
4. The system cost is high, and the external thermal insulation system construction process is more outside the outer wall, when adopting the heat preservation mortar as the heat preservation, generally divide into three (even more) plasters, and each plaster need to go on after the hardening of one previous plaster layer, and the heat preservation needs to add outward to put the anticracking layer, still needs to set up net cloth or wire net protective layer, does the decorative finish coat finally.
Disclosure of Invention
Aiming at the problem that the cost of the existing light imitation stone heat-preservation veneer mainly made of perlite is generally higher, the invention aims to provide the light imitation stone heat-preservation veneer with a decorative surface, which is light, heat-preservation, fireproof, waterproof, high-strength and ageing-resistant, by utilizing industrial waste residues of a heat-preservation plate on the premise of ensuring the quality of the imitation stone heat-preservation veneer.
In order to realize the purpose, the invention provides the following technical scheme: a light stone-like thermal insulation veneer is prepared by the following steps:
step one, preparing powder from the backing material: mixing 10 to 20 parts by weight of perlite, 30 to 60 parts by weight of heat-insulating material industrial waste residue, 5 to 10 parts by weight of bentonite, 8 to 15 parts by weight of zeolite, 5363 parts by weight of kaolin 5~8 parts by weight of granite grinding material, 0.2 to 1.0 part by weight of green ceramic silicon powder and 5 to 10 parts by weight of fluorite tailings, crushing, carrying out wet ball milling, carrying out uniform ageing, carrying out spray drying, granulating and pulverizing;
step two, milling the fabric: mixing raw materials of 15 to 30 parts by weight of perlite, 15 to 45 parts by weight of heat-insulating material industrial waste residue, 5 to 10 parts by weight of bentonite, 8 to 15 parts by weight of zeolite, 5363 parts by weight of kaolin 5~8 parts by weight of granite grinding material, 0.2 to 0.5 part by weight of green ceramic silicon powder and 5 to 10 parts by weight of fluorite tailings, crushing, carrying out wet ball milling, carrying out uniform ageing, carrying out spray drying, granulating and preparing powder;
step three, glaze preparation: ball-milling 40-60 parts of blank raw materials, 20-30 parts of albite, 20-30 parts of potassium feldspar and 5-10 parts of kaolin to obtain a glaze;
fourthly, using a press secondary material distribution system to form a ceramic heat-preservation decorative plate blank body in a one-step mode, and then drying the ceramic heat-preservation decorative plate blank body in a drying kiln;
step five, glazing: and glazing the blank by using a glaze material, and firing the glazed blank at the high temperature of 1100-1300 ℃ to form the light stone-like heat-insulating veneer with closed pores uniformly and densely distributed with glaze surfaces.
Further, in the first step, 12 to 20 parts of perlite, 30-60 parts of heat insulation material industrial waste slag, 3236 parts of bentonite, 8 to 12 parts of zeolite, 5262 parts of granite abrasive, 5262 parts of zxft, 0.2 to 0.8 parts of green ceramic silicon powder and 3763 parts of fluorite tailings.
In the second step, 8 to 12 parts of zeolite and 5~8 parts of granite abrasive are further used.
Further, in the third step, the blank raw material comprises 45-55 parts of albite, 22-28 parts of potassium feldspar and 6~8 parts of kaolin.
Furthermore, the light stone-like heat-preservation decorative panel comprises a blank body and a glaze surface, wherein the blank body is provided with closed air holes which are uniformly and densely distributed, and the blank body and the glaze surface are integrally arranged.
