Embodiment 1

[0053] A roof thermal insulation board is prepared by the following steps:

[0054] 1. Pouring surface layer

[0055] 1) Weigh 33kg of cement (P.O42.5R; the same below), 25kg of S95 slag powder, 87kg of sand, 1.2kg of brightener (MNC-CZ brightener for colored bricks of Muhu brand; the same below), 47kg of water, and mix Add it into the mixer and stir quickly for about 5 minutes to make cement mortar;

[0056]2) Pour cement mortar evenly into the mold that has been placed (the mold size is 300mm×300mm×100mm, and various patterns can be made on the mold according to user requirements to achieve an aesthetic effect), so that the mortar in each mold The thickness of the layer is about 5mm. Vibrate the mold slightly so that the mortar in it is fully spread in the mold, and continue to vibrate the mold to discharge the air bubbles in the mortar;

[0057] 3) After the fabric is poured, let it stand still and wait for the bottom layer to be poured;

[0058] 2. Pouring the bottom la...

Embodiment 2

[0065] A roof thermal insulation board is prepared by the following steps:

[0066] 1. Pouring surface layer

[0067] Operation is with embodiment 1 step 1;

[0068] 2. Pouring the bottom layer

[0069] 1) Weigh 0.9kg of Henan Huatai HTQ-1 composite foaming agent, add it to the foaming machine, and add 40kg of tap water to fully foam with compressed air;

[0070] 2) At the same time, weigh 440kg of cement, 189kg of S95 slag powder, 69kg of sand, 5.1kg of non-slow coagulation carboxylic acid high-efficiency superplasticizer, and 270kg of water, and add them to the mixer for mixing and stirring. First, stir slowly for 0.5 minutes, and then stir rapidly for about 1.5 minutes. Then add 18.9kg of curing agent (sodium chloride 15.12kg, calcium hydroxide 3.78kg), and then stir rapidly for 2 minutes to make the slurry uniform;

[0071] The rest of the steps are the same as Step 2, Step 3)-5) of Example 1. The obtained roof thermal insulation board is a heat insulation board with a...

Embodiment 3

[0073] A roof thermal insulation board is prepared by the following steps:

[0074] 1. Pouring surface layer

[0075] Operation is with embodiment 1 step 1;

[0076] 2. Pouring the bottom layer

[0077] 1) Weigh 0.8kg of Henan Huatai HTQ-1 composite foaming agent, add it to the foaming machine, and add 40kg of tap water to fully foam it by compressed air;

[0078] 2) At the same time, weigh 495kg of cement, 213kg of S95 slag powder, 77kg of sand, 5.7kg of non-slow coagulation carboxylic acid high-efficiency water reducer, and 305kg of water, and add them to the mixer for mixing and stirring. First, stir slowly for 0.5 minutes, and then stir rapidly for about 1.5 minutes. Then add 21.3kg of curing agent (sodium chloride 17.04kg, calcium hydroxide 4.26kg), and then stir rapidly for 2 minutes to make the slurry uniform;

[0079] The rest of the steps are the same as Step 2, Step 3)-5) of Example 1. The obtained roof thermal insulation board is a heat insulation board with a b...

Abstract

The invention discloses a roof heat preservation plate and a production method and application for the roof heat preservation plate. The roof heat preservation plate consists of a surface layer and a bottom layer; the thickness of the surface layer is 5-7mm; the thickness of the plate is 100-120mm, and the comprehensive density of the plate is 700-1000kg / m<3>; a production raw material of the surface layer comprises 15-19% of cement, 11-15% of slag powder, 41-47% of sand, 0-0.8% of brightening agents and 21-26% of water; and a production raw material of the bottom layer comprises 42-46% of cement, 15-20% of slag powder, 5.5-8.5% of sand, 0.45-0.80% of water reducing agents, 1.5-2.5% of curing agents, 0.07-0.25% of foaming agents and 25-29% of water. The roof heat preservation plate is convenient to construct, is light, heat-insulation, waterproof and fireproof, and is beneficial for energy conservation of a building, simple in production procedure and good in durability. The service life of the roof heat preservation plate is the same as that of main work.

Description

technical field [0001] The invention belongs to the field of light-weight, energy-saving and thermal-insulation building materials, and in particular relates to a roof thermal-insulation board and its production method and application. Background technique [0002] At present, there are several technical methods for roof insulation treatment of civil and industrial buildings: [0003] (1) Elevated bearing slabs, that is, several supporting low walls (about 120mm in height) are built with bricks on the roof slab, and then a layer of cement concrete slab (about 30mm thick) is laid on the supporting low walls, then An air layer is formed between the roof slab and the cement concrete slab to avoid the direct transfer of sunlight radiant heat to the room on the top floor. This method can play a role of heat insulation to a certain extent in the hot season, but in the cold season, it cannot prevent the heat from the top room from radiating outwards, and it cannot play the role of...
