Embodiment 1

[0022] (1) Preparation of insulation layer: Chop the crop straw into pieces with a length of 0.5-1.5mm, and then weigh 30 parts of the chopped crop straw, 30 parts of magnesium cement, 15 parts of polystyrene foam particles, plant hair 10 parts of foaming agent, 20 parts of glass microspheres, and 10 parts of glass fiber are placed in a stirred reactor, an appropriate amount of water is added, and mixed and stirred at a speed of 50-80 rpm for 1-3 hours to obtain a mixed foaming material slurry. Then inject the above-mentioned slurry into a cuboid mold with a depth of 5 mm, smooth the surface, and press at room temperature for 2 to 3 hours to obtain a cuboid block insulation layer;

[0023] (2) Prepare the protective inner layer mixture: put the high-phosphorus soil at 800°C for 2 hours to calcine metakaolin, crush and grind the construction waste into granules with a particle size of 0.05-0.08mm, then weigh 30 parts of metakaolin, Put 20 parts of construction waste crushed mat...

Embodiment 2

[0029] The difference from Example 1 is that the raw materials of the protective outer layer include: 70 parts of cement, 40 parts of fly ash, 10 parts of ultraviolet refraction agent, and 8 parts of anti-cold agent; the raw materials of the thermal insulation layer include: 40 parts of crop straw parts, 40 parts of magnesium cement, 20 parts of polystyrene foam particles, 15 parts of plant foaming agent, 25 parts of glass microspheres, and 15 parts of glass fiber; the raw materials of the protective inner layer include: 50 parts of metakaolin, crushed construction waste 40 parts of material, 30 parts of binder, wherein, the particle size of the crushed construction waste material is 0.08mm.

[0030] The thickness of the mold in the preparation step (1) is 15 mm, and the thickness of the mold in the preparation step (4) is 22 mm.

[0031] The multilayer composite multifunctional wall insulation material prepared by the above method has a protective outer layer with a thickness...

Abstract

The invention discloses a preparing method of a composite multi-layer multi-functional wall heat-preserving material. The heat-preserving material comprises a protective outer layer, a heat-preserving layer and a protective inner layer. The inner surface and the outer surface of the heat-preserving layer are covered with the protective outer layer and the protective inner layer respectively. The side face of the side, opposite to the heat-preserving layer, of the protective inner layer is of a water ripple or sawtooth structure. The preparing method includes the following steps of (1) preparing the heat-preserving layer, (2) preparing protective inner layer mixed materials, (3) preparing protective outer layer mixed materials, (4) preparing a heat-preserving material and (5) polishing and forming. The preparing method is simple in process procedure and convenient to operate; the prepared heat-preserving material of a three-layer composite structure has excellent fire resistance, heat preservation, weather resistance and anti-compression performance, and by means of the water ripple or sawtooth structure of the inner-layer wall, the composite multi-layer multi-functional wall heat-preserving material can be combined with a wall well. The composite multi-layer multi-functional wall heat-preserving material prepared in the method is obvious in structural feature, excellent in comprehensive effect, low in cost and durable and has wide market prospects.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a preparation method of a multilayer composite multifunctional wall thermal insulation material. Background technique [0002] Wall insulation material is the main raw material for building energy conservation, and its application and development play a vital role in the field of building energy conservation. At present, most of the widely used wall insulation materials are of integrated structure, and the insulation layer is directly exposed outside. After being exposed to the sun and wind and rain, the insulation effect is reduced, the service life is shortened, the insulation layer is replaced frequently, and a lot of manpower and labor are wasted. Material resources; moreover, the integrated thermal insulation material has certain limitations in fire resistance, and fires caused by thermal insulation materials have become common occurrences, causing certain losses ...
