The existing heat preservation and insulation board is developed in the direction of light weight, is mostly realized by adopting organic materials through methods such as foaming and the like, has the advantages of light weight, good heat insulation property, good moisture resistance, corrosion resistance, ageing resistance, easiness in carrying and cutting and the like, but has the problems of not ideal strength performance and easiness in burning under open fire to generate a large amount of smoke and toxic gas.
Disclosure of Invention
The invention aims to provide a light homogeneous fireproof heat-insulation board, which solves the technical problems of poor flame retardant property and unsatisfactory specific strength of the existing light heat-insulation board.
In order to solve the technical problems, the invention provides a light homogeneous fireproof insulation board which is mainly prepared from the following components in parts by weight:
in the invention, the magnesium oxide, the magnesium chloride and the fly ash are all inorganic non-combustible materials, so that the flame retardant property of the light homogeneous fireproof insulation board can be effectively improved. Wherein, the active content of the magnesium oxide is preferably more than 65 percent; the purity of the magnesium chloride is preferably 46% or more.
The fly ash has potential volcanic ash activity and can be activated to exert the activity. The fly ash used in the invention is preferably national standard first-grade ash, the particles of the national standard first-grade ash are small, the structure of the fly ash is broken down, the internal soluble SiO2 and A12O3 are released, the network polymer is depolymerized into low-polymer aluminosilicate colloid, and the potential volcanic ash activity of the fly ash is excited.
The polystyrene particles are prepared by expanding and foaming a polystyrene material, contain a large number of closed bubbles, have the characteristics of small density, low heat conductivity coefficient, no water absorption and the like, can effectively improve the heat insulation performance and the waterproof performance of the light homogeneous fireproof heat-insulation board, and have extremely strong corrosion resistance and mildew resistance; the polyphenyl particles can also provide framework support for the light homogeneous fireproof heat-insulation board, the polyphenyl particles are low in elastic modulus and excellent in toughness, and can absorb energy through elastic deformation when being subjected to external force, so that the compressive capacity and the crack resistance of the light homogeneous fireproof heat-insulation board can be improved.
The sodium bentonite and the acrylic emulsion can play a role in increasing viscosity, and the bonding force among all components in the light homogeneous fireproof heat-insulation board is enhanced, so that the effect of improving the strength of the light homogeneous fireproof heat-insulation board is achieved; the sodium bentonite can also have the effect of increasing the closed pore rate, and the acrylic emulsion has good film forming property and can obviously enhance the waterproof effect of the light homogeneous fireproof insulation board. Wherein, the sodium bentonite is preferably a product with the expansion ratio of 35-40 times; the acrylic emulsion is preferably styrene-acrylic emulsion with solid content of 48 +/-2%, and the styrene-acrylic emulsion is low in price and excellent in film-forming property.
The calcium stearate can improve the plasticity of slurry for producing the light homogeneous fireproof insulation board, and is beneficial to the processing and production of the light homogeneous fireproof insulation board; the waterproof performance of the light homogeneous fireproof heat-insulation board can be effectively improved. The purity of calcium stearate is preferably 98% or more.
The foaming agent can be prepared into abundant and stable foam, and the foam is mixed with slurry prepared from other raw materials to prepare the light homogeneous fireproof insulation board, so that the requirements of light quality and small heat conductivity coefficient of the light homogeneous fireproof insulation board can be met. The foaming agent adopted in the invention can be selected from animal protein foaming agents and other foaming agents commonly used in the construction industry.
Further, the insulation board also comprises 0.9-1.1 parts by weight of anionic surfactant. The anionic surfactant and the animal protein foaming agent are compounded for use, so that the generated foam is richer and more stable, and the foam is ensured not to crack when being mixed with slurry; on the other hand, the anionic surfactant can increase the binding force between the polyphenyl particles and the magnesium oxide, the magnesium chloride and the fly ash, so that the strength of the light homogeneous fireproof insulation board is improved. The anionic surfactant can be selected from sodium dodecyl benzene sulfonate, sodium dodecyl sulfate, etc.
Further, the polyphenyl granules are prepared from granules with the grain diameter of 1.5mm and the grain diameter of 3mm according to the weight part ratio of 1:1, and mixing the components in a ratio of 1. The particles with two particle sizes are mixed to achieve an ideal filling effect, so that the product cost can be reduced, and the adverse effect of the increase of the gaps among the particles on the density of the light homogeneous fireproof insulation board, which is caused by the filling of the large particles, can be avoided.
Further, the preparation method of the heat-insulation board comprises the following steps:
(1) dissolving sodium bentonite with appropriate amount of water into slurry liquid 24h in advance, and swelling;
