[0006] 2. Large energy consumption and heavy pollution:
[0008] 3. The small block is big:
[0010] 4. Poor insulation performance:
[0011] The thermal conductivity of sintered clay red brick is 0.81w / m.k, the wall insulation effect of the building is poor, and the energy consumption is large
[0012] The thermal insulation methods used in buildings are all composite thermal insulation. High pollution and high energy consumption are common in the production process of composite thermal insulation materials. Inflammable, falling off, toxic, and different lifespan from buildings are common in the process of use, which increases the cost and makes construction difficult. , fall off causing personal injury, vehicle damage and other issues

specific Embodiment approach 1
[0027] Specific implementation method 1: The self-insulating lightweight aggregate module in this embodiment is composed of A: one or more of lightweight aggregate, ceramsite or scouring sand, B: stone material, C: cement and D: foam According to each cubic meter, A accounts for 60-100% of the volume of the module, B accounts for 0-40% of the volume of the module, the amount of C is 100-150Kg, and the amount of D is 100-1000g.
[0028] like figure 1 As shown, the specific preparation steps of the self-insulating lightweight aggregate module in this embodiment are as follows:
[0029] According to the proportion of raw materials, add cement and foaming agent for forced mixing, mold pouring molding or demoulding cutting molding, without extrusion, so that the density of the product is relatively reduced, and the weight of the produced product is less than 900 kg. This molding method Most of the products are mainly filling walls, and the specifications can be adjusted and cut ac...
specific Embodiment approach 2
[0035] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the self-insulating lightweight aggregate module is composed of A: one or more of lightweight aggregate, ceramsite or scouring sand, C: cement and D: hair Foaming agent is prepared.
specific Embodiment approach 3
[0036] Specific embodiment 3: The difference between this embodiment and specific embodiment 1 is that the self-insulating lightweight aggregate module is composed of A: one or more of lightweight aggregate, ceramsite or scouring sand, B: stone material, C : cement and D: foaming agent, the A accounts for 60-90% of the volume of the module, and B accounts for 10-40% of the volume of the module.

Abstract
The invention discloses a self-heat-insulated lightweight-aggregate module. Self-heat-insulated products of different weights and strengths are produced through sintering wastes such as tailings, sludge, coal gangue, shale and pulverized coal ash so as to prepare lightweight aggregates or haydite, taking the lightweight aggregates or haydite and panned sand (the main aim is to lighten weight and improve stability and strength) as main homemade raw materials, preparing stony materials such as volcanic rock (basalt and pumice), of which the volume weight is smaller than 1,200kg, adding a certain ratio of cement as a cementing agent, and then, adding a proper foamer in a matched use manner. According to the self-heat-insulated lightweight-aggregate module, the materials used are all wastes and industrial waste residues, the disadvantage of building is overcome, and a great contribution to environmental governance is made, so that the self-heat-insulated lightweight-aggregate module is a good multipurpose product.
Description
technical field [0001] The invention belongs to the technical field of wall materials, and relates to a self-insulating lightweight aggregate module that can be used as blocks, bricks and wall panels. Background technique [0002] The construction industry is a large consumer of resources and energy, and the country consumes 4 billion tons of raw coal every year. Among them, building energy consumption (heating, cooling) accounts for about 30% of the total domestic energy consumption. [0003] Sintered brick is a material widely used in construction. Due to the great damage to land resources in the process of obtaining materials, there are still high pollution and high energy consumption in the sintering process. The production of red bricks has seriously threatened land resources and The ecological environment, specifically: [0004] 1. Large consumption of land resources: [0005] Taking Heilongjiang as an example, there are more than 1,200 sintered brick factories, wit...
