Novel composite building energy-saving building block and manufacturing method thereof

Abstract

The invention discloses a novel composite building energy-saving building block and a manufacturing method thereof. The building block is characterized in that two vertically staggered rows of hole grooves are provided on a microporous lightweight concrete block, wherein each row of hole groove is separated into 2 holes by a rib. Insulation molded polystyrene boards and vermiculite boards are arranged in the holes with a staggered manner. The manufacturing method comprises the point that: a microporous lightweight concrete slurry is composed of common Portland cement, fast-hardening sulphoaluminate cement, vermiculite powder, spontaneous-combustion coal gangue powder, alkali-resistant chopped crack-resistant reinforcing fiber, a high-efficiency dispersing agent, and a foaming agent. The vermiculite boards are prepared through the steps that: vermiculite powder, phenolic resin, and silicone emulsion are blended; and the obtained material is subjected to extrusion molding in a mold. The building block provided by the invention has the advantages of good thermal insulation effect, high strength, and no fire hazard risk. The building block can be widely applied as building insulation and energy-saving building blocks.

Description

1. Technical field [0001] The invention relates to building wall heat preservation and energy-saving technology, in particular to a novel composite building energy-saving block and a manufacturing method thereof. 2. Background technology [0002] High-rise buildings are mostly frame structures, and their walls are generally filled with blocks. Because the country has energy-saving standards for buildings, the walls must have thermal insulation. At present, the blocks used in construction are generally made of adhesive paste mixed with heat-insulating granular aggregates. Its disadvantages are low strength and poor cohesiveness, which affect the subsequent plastering process and are easy to form hollows. On the other hand, the thermal conductivity is high, which cannot reach the 65% energy-saving standard required by the state. Some walls are thermally insulated by pasting benzene boards on the exterior walls. Although the heat insulation effect is improved, the large area o...

AI Technical Summary

Problems solved by technology

At present, the blocks used in construction are generally made of adhesive paste mixed with heat-insulating granular aggregates. Its defects are low strength and poor cohesion, which affect the subsequent plastering process and are easy to form hollows.

On the other hand, the thermal conductivity is high, which cannot meet the 65% energy-saving standard required by the state.

Some walls adopt the method of pasting benzene boards on the outer wall for heat insulation. Although the heat insulation effect is improved, but the large area of ​​the outer wall is pasted with benzene boards, burying fire hazards, which is not conducive to fire protection.
