A multifunctional foamed concrete composite self-insulating block and its forming method

Abstract

The invention relates to a multifunctional foamed concrete composite self-heat-preservation block and a forming method thereof. The center of a block body is provided with a middle cavity for filling or pouring foamed materials, and the hollow cavity is a through hole with openings located in end faces of double sides, or a blind hole with an opening located in the end face of one side or a blind hole with an opening located in the side wall of one side; the middle cavity is filled with the foamed materials to form a double-foamed block, or the middle cavity is filled with the foamed materials and naturally shrinks to form a double-foamed block with a hollow chamber. The forming method comprises the steps: firstly, making a die box of the block as required, then, sorting, stirring, foaming and pouring in the die box, and distilling by using an autoclave to obtain a hollow shell, wherein the hollow shell is solid outside and is provided with the middle cavity; and (2) pouring the foamed materials into the middle cavity of the hollow shell in a physical or chemical foaming way according to the ratio of less than 300kg / cubic capacity, and then, forming through natural curing or secondary distilling, wherein the hollow shell is prepared in the step (1). The inner hole of the block provided by the invention is subjected to hollow treatment, so that the heat self-preservation and energy saving effects are good.

Description

technical field [0001] The invention relates to building blocks for environment-friendly and energy-saving buildings, in particular to a multifunctional foamed concrete composite self-insulating block and a forming method thereof. Background technique [0002] As green and environmentally friendly buildings are expected by more people in the society, as the material used for the enclosure wall, which accounts for 30% of the building energy consumption, it is the most important thing to be concerned by the industry. Although some products such as ceramsite with multiple rows of holes or insert Technological forms such as EPS polystyrene board make the wall meet the technical index requirement of building energy saving of 50%. Although the mature product aerated concrete block has good heat insulation effect, it is greatly affected by the environment and climate, it is not waterproof, the heat preservation effect is extremely unstable, and it is easy to cause peeling, heat pre...

Problems solved by technology

[0003] The purpose of the present invention is to improve and innovate on the shortcomings and problems existing in the background technology, to provide a combination of the advantages of different wall materials at present, and to fundamentally solve the several aerated foamed concrete block products currently used in my country's walls The problem of heat insulation can not be completed in one step, and the product is light but not high-strength, high-strength and heavy-weight, and not fireproof or waterproof. In order to realize the direct self-insulation of wall materials and synchronize with the life of the building, and use composite technology to produce a kind of instant Multifunctional foamed concrete composite self-insulation block with environmental protection, ecology, safety, fire prevention, anti-seepage, reasonable cost, simple production method and high added value and its forming method
