Embodiment 1
[0016] Take 28 parts of cinder, 25 parts of fly ash, 12 parts of desulfurized gypsum, 22 parts of thermal insulation ceramsite, 3 parts of lignocellulose, 15 parts of cement, 10 parts of quartz sand, and appropriate amount of water (depending on the water content of raw materials, add Stir the mixed material after water, grasp it into a ball by hand, and do not disperse after letting go), put it into the mixing container, stir for 5-8 minutes, and then transport the mixed material to the block forming machine by machine for extrusion Forming, and then use machinery to transfer the extruded blocks to the indoor static maintenance rack, maintain for 11-13 hours, then transfer the blocks to the outside, and cover them with sunshade nets for about 170 hours, and then continue to maintain for 26- After 29 days, it can be inspected and leave the factory.
Embodiment 2
[0018] Take 30 parts of cinder from fluidized fluidized furnace, 26 parts of fly ash, 13 parts of desulfurized gypsum, 23 parts of thermal insulation ceramsite, 4 parts of lignocellulose, 16 parts of cement, 11 parts of quartz sand, and appropriate amount of water.
[0019] All the other implementations are as in Example 1.
[0020] Take 31 parts of cinder from fluidized fluidized furnace, 24 parts of fly ash, 14 parts of desulfurized gypsum, 24 parts of thermal insulation ceramsite, 4 parts of lignocellulose, 14 parts of cement, 12 parts of quartz sand, and appropriate amount of water.

Abstract
The invention discloses a light-weight energy-saving thermal insulating brick which is prepared by stirring, mixing, extrusion forming and maintaining the following raw materials according to the parts by weight: 20-40 parts of low-calorie coarse slag, 20-30 parts of fly ash, 5-20 parts of desulfurized gypsum, 10-30 parts of thermal insulating ceramic particles, 1-5 parts of wood cellulose, 10-20 parts of cement, 5-15 parts of quartz sand and appropriate amount of water. The average value of the heat transfer resistance (m.K)/W of the light-weight energy-saving thermal insulating brick is 0.97, and the average value of the compressive strength is 11.2. The thermal insulation performance of the invention is good and the strength of the invention is high, thereby being applicable to masonry of bearing walls and non-bearing walls.
Description
Technical field: [0001] The invention relates to building materials, in particular to thermal insulation blocks for building walls. Background technique: [0002] With the progress of society, saving energy has become a consensus. In order to save land and energy and improve the thermal insulation and heat insulation functions of buildings, concrete small hollow blocks have been widely used in wall masonry. In recent years, in order to further enhance the thermal insulation effect of the blocks, polystyrene foam thermal insulation materials are filled in the hollow holes of the blocks, and the walls are built with such blocks, and the thermal insulation, sound insulation, and moisture-proof effects have been improved. greatly enhanced. However, the labor intensity of the workers in the preparation process of this kind of block is high (manually filling the thermal insulation material in the reserved hole of the block), and at the same time, because the thermal insulation m...
