Abstract

The invention discloses a sandwiched mortar heat-insulating / warm-keeping block which is a novel functional wall block having multiple building functions of energy saving, environment protection, heat insulation, warm keeping, fire prevention and noise absorption. The invention further discloses preparation and application of the sandwiched mortar heat-insulating / warm-keeping block. A warm-keeping / heat-insulating layer is arranged in the middle of the sandwiched mortar heat-insulating / warm-keeping block, mortar concrete is arranged at both sides of the warm-keeping / heat-insulating layer, and the sandwiched mortar heat-insulating / warm-keeping block is formed by carrying out vibration and extrusion forming on the warm-keeping / heat-insulating layer and the mortar concrete. The heat-insulatinglayer of the mortar warm-keeping block provided by the invention has stable structure, and the heat-insulating / warm-keeping layer is combined with the block into a whole and can not fall off easily. Thus, the prepared block is durable, thereby being a favorable novel wall material having the functions of heat insulation, warm keeping, fire prevention, energy saving, emission reduction and environment protection.

Description

Technical field [0001] The invention relates to a building wall material, in particular to a sandwich mortar heat-insulating building block with the functions of energy saving, environmental protection, heat insulation, sound insulation, sound absorption and fire prevention, and its preparation and application. Background technique [0002] In the prior art, most of the building energy-saving materials with thermal insulation effect are pasted or painted on the outer wall of the wall. As time goes by, after a long period of wind and rain, sun and rain, and seasons Due to changes, these materials will change, and thermal expansion and contraction will cause irregular cracks and water seepage of the wall material, and lose the original thermal insulation function. At the same time, the aging and shedding of the stucco layer on the wall will not only affect the appearance, but also cause safety hazards. For example, the Chinese invention patent 02153345.8 discloses a rubber powder ...
