Fireproof insulation plate and preparation method thereof

Abstract

The invention discloses a fireproof insulation plate and a preparation method thereof. The fireproof insulation plate is made of fireproof insulation materials which comprise a composition A and a composition B; the composition A comprises, by weight, 80-120 parts of aluminum silicate fiber, 100-140 parts of sepiolite fiber, 40-60 parts of dioctyl sulfosuccinate, 2000-2500 parts of water, 40-60 parts of polyvinyl alcohol, and 15-30 parts of graphite powder; the composition B comprises, by weight, 600-800 parts of sulphoaluminate cement and 5-10 parts of water repellents. According to the fireproof insulation plate, the per unit volume weight range is 150-200 kg / m<3>, the volume weight and the thermal conductivity are low, and the construction is convenient; a foam hole structure and added fiber make the fireproof insulation plate have certain elasticity and excellent mechanical strength and not easy to fragment during the construction; the fiber is beneficial to disperse temperature stress and prevent the plate from fragmenting.

Description

technical field [0001] The invention relates to the technical field of building energy-saving materials, in particular to a fireproof heat preservation board and a preparation method thereof. Background technique [0002] One of the most important measures for building energy saving is to establish an insulation and energy-saving system for the wall. At present, the wall insulation and energy-saving system in my country mainly includes the internal insulation system of the external wall, the sandwich insulation system of the wall and the external thermal insulation system of the external wall. With its many advantages, the energy-saving system of external thermal insulation of external walls has become the mainstream of wall thermal insulation. At present, in the external insulation system, the materials used for the insulation layer are mainly polystyrene expansion board (EPS), extruded plastic board (XPS), and polyurethane board. Although their thermal conductivity is low,...

Problems solved by technology

However, the thermal conductivity of perlite plates is generally above 0.06, and the bulk density is 300kg / m 3 , in order to achieve the same energy-saving requirements, the thickness of the perlite sheet is about twice the thickness of the organic insulation material, and the weight of the sheet used is about 20 to 30 times that of the organic insulation sheet, which brings great benefits to the practical application of the perlite insulation sheet. There are many problems such as the difficulty of wall construction and the easy fall of the board

At present, inorganic fireproof and thermal insulation materials based on perlite still have disadvantages such as poor thermal insulation effect, large bulk density, easy breakage, poor mechanical strength, poor nail holding power and difficult construction.

Rock wool has the advantages of high thermal insulation and fire resistance. It is a class A-grade insulation board commonly used at present. However, this type of board also has disadvantages such as large production energy consumption, easy moisture absorption, difficult construction, and extremely low strength. During the process, there will be problems such as easy falling, easy falling off of the surface mortar and serious decline in thermal insulation performance.

Foamed cement has the advantages of low cost, easy production and processing, and its fire performance is Class A. It can be used as filling walls in building interiors. In recent years, it has also been used as thermal insulation materials. However, it is a brittle material, which is difficult to construct and has poor weather resistance.

Therefore, there are some insurmountable disadvantages in the application of inorganic thermal insulation boards in building thermal insulation.
