Foam concrete function gradient composite board and preparing method thereof

Abstract

The invention discloses a foam concrete function gradient composite board and a preparing method thereof. The foam concrete function gradient composite board is a board body, comprising an upper protection layer and a lower protection layer as well as a thermal insulation layer between the two protection layers; two transverse ends of the board body are respectively provided with a groove and a tenon for connecting and positioning; a frame layer is paved in the thermal insulation layer and longitudinally penetrates through the thermal insulation layer and extends into the upper and lower protection layers to connect the upper and lower protection layers and the middle thermal insulation layer into a whole; the thermal insulation layer and the protection layers are formed by adopting continuous pouring; decoration layers are arranged at outer surfaces of the two protection layers; the frame layer is woven by FRB ribs. The foam concrete function gradient composite board prepared by the preparing method can be used for construct a novel building wall body and a roof surface system integrating multiple functions of fire prevention, thermal insulation, decoration and durability and has very wide popularization and application values.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a foam concrete functionally graded composite board and a preparation method thereof. Background technique [0002] Building energy conservation and building industrialization have become the preferred theme and development focus in the field of urbanization and urbanization development, and are also the greatest needs for improving people's livelihood. For this reason, the "Green Building Action Plan" formulated by the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development pointed out that during the "Twelfth Five-Year Plan" period, 1 billion square meters of new green buildings will be completed; by the end of 2015, 20% of new urban buildings will reach The green building standards require that 50 million square meters of existing buildings be retrofitted with energy conservation in hot summer and cold winter areas, and 120 million s...

Problems solved by technology

The above-mentioned insulation board materials generally have the characteristics of light weight and good thermal insulation performance, but at the same time there are other defects: 1) For inorganic insulation materials such as expanded perlite boards, aerated concrete boards, and ceramsite concrete board, etc., due to the high water absorption and water storage rate of the thermal insulation material, it is easy to absorb moisture into the material after encountering water, resulting in a serious loss of thermal insulation performance. It will damage the structure and crack easily, so that the durability of the insulation system will seriously not match the life of the structure

2) For organic polymer insulation materials, such as polystyrene foam (EPS) boards, extruded polystyrene foam (XPS) boards, etc., there are different degrees of complex construction, poor aging resistance or insufficient fire resistance And other issues

[0009] The utility model patent application number CN201220736399.6 discloses a foam concrete hollow wall plate with a steel grid frame and the foam concrete wall plate disclosed by the utility model patent publication number CN201220740382.8 are both foam concrete single Laminate panels have a single function, no waterproof and decorative functions, and the foam concrete has low strength, slag, looseness, easy damage, difficult handling, and inconvenient installation, which restricts engineering applications
