Self-insulation hollow block brick for wall and preparation method thereof

Abstract

The invention discloses a self-insulation hollow block brick for a wall and a preparation method thereof. The self-insulation hollow block brick for the wall comprises a block brick body, wherein three or more than three rows of elongated through holes penetrating through the block brick body in the thickness direction are formed in the block brick body; two side surfaces in the length direction of the block brick are smooth surfaces; two side surfaces in the width direction of the block brick are provided with through grooves penetrating the block brick body in the thickness direction; the length of the block brick is 355-365 mm, the width of the block brick is 235-245 mm, and the thickness of the block brick is 235-245 mm. The self-insulation hollow block brick for the wall is low in heat conductivity coefficient, good in low temperature resistance, high in compressive strength and light in weight; the insulation effects of a common brick and a block are integrated, the effects of insulating heat and saving energy by 65-70 percent can be achieved, and the process of manufacturing an insulation layer outside the wall is eliminated; moreover, raw materials are easily obtained, corrosion and pollution are avoided, the safety is high, component materials can be recycled, the binding power is high, the cost is low, and the self-insulation hollow block brick for the wall has the performances such as static resistance and incombustibility.

Description

technical field [0001] The invention relates to a self-insulating hollow block brick for walls and a preparation method thereof, belonging to the field of construction. Background technique [0002] With the increasing scarcity of global energy, building wall insulation has become an important topic in the field of building energy conservation, and the thermal performance of building walls is achieved through the combination of external insulation materials such as EPS boards or XPS boards. Achieved. The combination of external wall insulation materials is the most widely used thermal insulation technology at present, but the material price of this technology is high, the work efficiency is low, and the safety hazard of installation is relatively large. In recent years, there have been many cases related to external wall insulation in my country. fire accidents, the fire protection of external wall insulation has attracted the attention of all walks of life. [0003] In ord...
