Embodiment 1

[0081] (1) Mix 5 parts by weight of graphene and 20 parts by weight of water, and ultrasonically process to obtain graphene nano-dispersion for use.

[0082] (2) Add 3 parts by weight of the foam stabilizer, 0.8 parts by weight of the early strength agent and 0.6 parts by weight of the water reducing agent into the premixer and stir to form a premix.

[0083] (3) Add the graphene nano-dispersion of step (1), 5 parts by weight of fibers, 4.4 parts by weight of premix and 60 parts by weight of water into the mixer, stir for 20 minutes, and then add 100 parts by weight of aluminate cement, and stir to form Pure pulp.

[0084] (4) Add 7 parts by weight of the foaming agent to the pure slurry of step (3), stir evenly, and pour into the mold. Before pouring, the mold should be brushed with release agent to ensure that every corner of the mold is brushed. After pouring is completed, immediately put the mold into the curing room for foaming, demoulding after 24h, and further curing for 10 ...

Abstract

The invention discloses a heat insulation plate and a preparation method thereof. The heat insulation plate uses inorganic materials as major ingredients, and is prepared from the following ingredientraw materials including 100 parts by weight of cement, 1 to 7 parts by weight of graphene, 30 to 100 parts by weight of water, 2 to 10 parts by weight of fiber, 4 to 10 parts by weight of foaming agents, 1 to 5 parts by weight of foam stabilizers, 0.5 to 1.5 parts by weight of early strength agents and 0.1 to 2 parts by weight of water reducing agents. The comprehensive performance of the heat insulation plate is further improved.

Description

Technical field [0001] The invention relates to a thermal insulation board and a preparation method thereof, in particular to an external wall thermal insulation board and a preparation method thereof. Background technique [0002] With the rapid development of my country's infrastructure construction, the energy-saving requirements of building materials have gradually increased. The external wall insulation system can make the indoor temperature change slowly and the indoor thermal environment is more stable, thereby improving the environmental comfort. [0003] External wall insulation boards are divided into organic insulation boards and inorganic insulation boards. Organic thermal insulation panels include polystyrene panels (EPS), extruded plastic panels (XPS), etc., which have good thermal insulation effect, light weight and low cost. However, organic thermal insulation panels such as EPS and XPS are easy to deform, and thermal expansion and contraction in cold and hot envi...
