Abstract
The invention belongs to the technical field of building heat-insulating materials, and particularly relates to a manufacturing method of a building external wall heat-insulating and decorating integrated plate/brick and a prepared heat-insulating plate/brick, wherein the manufacturing method comprises decorative fine stone concrete press forming, gluing, composite forming, maintenance and the like; due to the tenon-and-mortise structure, the problem of heat loss between the plates/bricks is effectively solved.
Description
Technical Field
The invention belongs to the technical field of building heat insulation materials, and particularly relates to a manufacturing method of a building external wall heat insulation and decoration integrated plate/brick and a prepared heat insulation plate/brick.
Background
The building external wall heat preservation and decoration integrated product is a novel building energy-saving product widely popularized by China. The building outer wall heat insulating and decorating integrated board consists of heat insulating material, decorating surface layer material, etc. and is composite board prefabricated in factory. The decorative surface layer materials in the composite board have two types: (1) Fluorocarbon metallic paint, real stone paint, rock slice paint, flower paint and the like are taken as main materials; (2) The material is mainly made of decorative metal, ceramic, stone and other thin materials, and is compounded with a heat insulation material through organic glue. The existing building exterior wall insulation and decoration integrated board has the outstanding problem that the board is not weather-resistant, and the paint decoration layer and the organic adhesive binder begin to crack and fall off after being used for 3 to 5 years, because the organic film forming substances in the paint decoration layer are easy to age and fall off under the comprehensive action of outdoor rainwater, oxygen, ultraviolet rays and freeze-thaw cycles; the organic glue between the heat-insulating layer and the decorative layer sheet material is subjected to interface separation under the stress change caused by the temperature difference effect, and the organic glue is aged.
A gap between the building external wall heat-insulation and decoration integrated plates is a water seepage and heat transfer channel, and at present, various sealants can be adopted to treat the water seepage problem, but the heat insulation is not well treated. With the increasing requirements for heat preservation and energy conservation (such as ultra-low energy consumption and near-zero energy consumption buildings), the heat preservation layer is thicker (such as more than 200mm thick and more than 100mm thick which are called bricks), and the heat preservation treatment of the gaps between the plates/bricks is particularly important.
Disclosure of Invention
The invention aims to provide a method for manufacturing a building external wall heat-insulation and decoration integrated plate/brick and a prepared heat-insulation plate/brick.
In order to achieve the purpose, the invention adopts the technical scheme that:
a method for manufacturing a heat-insulating and decorating integrated plate/brick for an external wall of a building comprises the following steps:
s1, preparing a decorative fine aggregate concrete mixture: putting 200-400 parts of cement, 0-200 parts of fly ash, 50-150 parts of heavy calcium powder, 5-40 parts of pigment, 2-8 parts of waterproof agent, 400-800 parts of fine stone and water into stirring equipment according to the water-cement ratio of 0.3-0.4, and stirring to obtain a dry hard decorative fine stone concrete mixture, wherein the water-cement ratio is the mass ratio of water to a cementing material, and the cementing material comprises the cement and the fly ash;
s2, pressing and forming decorative fine aggregate concrete: filling the obtained dry and hard decorative fine stone concrete mixture into a mould, and performing pressing treatment to obtain a semi-finished decorative layer;
s3, sizing: before the semi-finished product of the decorative layer is finally set, a cement-based binder is laid on the top of the semi-finished product, and an alkali-resistant glass fiber mesh cloth is pressed in the semi-finished product of the decorative layer and is pressed in the cement-based binder;
s4, composite forming: before the cement-based binder is solidified, placing the inorganic insulation board on the cement-based binder layer and pressing the inorganic insulation board into the cement-based binder layer for 2mm;
s5, maintenance: and (5) curing the composite molded integrated board obtained in the step (4) for 14 days under the conditions that the temperature is 5 to 40 ℃ and the relative humidity is more than 80%, and drying for 7 days under natural conditions to obtain a finished product of the heat-insulation decorative integrated board/brick, wherein the compressive strength of the decorative fine aggregate concrete in the finished product is not lower than 30MPa.
Further, the fly ash in the step S1 is a secondary fly ash or a primary fly ash; the fine stone is limestone gradation particles with the particle size not more than 5 mm; the waterproof agent is alkali-resistant organic silicon waterproof powder or stearate; the cement is at least two of general portland cement, white portland cement and white sulphoaluminate cement; the heavy calcium carbonate powder is white calcium carbonate powder with the granularity of more than 800 meshes; the pigment is at least one of ferric oxide, chromium oxide, titanium oxide and cobalt oxide.
Further, the decorative fine aggregate concrete material in the step S1 comprises the following components in parts by mass: 230-300 parts of cement, 0-150 parts of fly ash, 80-120 parts of heavy calcium carbonate powder, 10-30 parts of pigment, 3-6 parts of waterproof agent, 400-700 parts of fine stone and 0.33-0.38 of water-cement ratio.
