Description

Refractory integrated plate, manufacturing method thereof and refractory combined plate

Technical Field

The present invention relates to a refractory integrated plate, a method for manufacturing the same, and a refractory composite plate.

Background

At present, polystyrene boards (EPS or SPS) are mostly adopted as heat insulation or heat insulation boards in the building industry, and the polystyrene boards (EPS or SPS) can be conveniently installed on the outer wall of a building so as to obtain a very good heat insulation effect.

However, the polystyrene board (EPS or SPS) has poor flame retardant performance, and even has combustion supporting effect when reaching a certain temperature, which is very disadvantageous to the fire safety of buildings.

Correspondingly, other heat preservation and insulation modes of buildings, such as heat preservation mortar, have certain flame retardant performance, but the heat preservation effect is far inferior to that of polystyrene boards. If the polystyrene board is added into the cement board layer in order to improve the heat preservation and insulation effect, the flame retardant effect of the polystyrene board is greatly influenced.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a plate with heat preservation and insulation effects close to polystyrene boards (EPS or SPS) and a manufacturing method thereof, and the plate is easy to be installed on the outer wall or the inner wall of a building and has better heat-resistant and flame-retardant effects.

a method of making a refractory integrated panel, comprising the steps of:

and (3) putty treatment of cement: adding silica sol solution or water glass solution into cement, adding 1-10% glass fiber, adding sand, mixing, adding water, and stirring to obtain cement putty;

a lower die step: attaching the cement putty to the inner wall of the lower mold;

cement foaming step: adding glass fiber and sand into the cement subjected to foaming treatment, stirring to form foamed cement, and injecting the foamed cement into the lower mold;

a step of die mounting: covering an upper die on a lower die so that the foamed cement forms a shape corresponding to that of the upper die;

heating and demolding: and heating the upper die and the lower die, and then demolding to form the refractory integrated plate.

Preferably, in the step of cement putty, the content range of the sand can be 40-80% of the weight of the cement putty; in the cement foaming step, the sand content may range from 40 to 80% by weight of the foamed cement.

Further, quartz sand or fine sand of 40 to 100 may be selected as the sand.

The fire-resistant integrated plate manufactured by the technical scheme has good heat insulation effect, can resist the high temperature of 1000 ℃ and still does not deform and burn after being proved by tests.

As the cement foaming step adopts the technical measures, tests prove that the strength of the obtained foaming cement is greatly improved, and the strength requirement of the prepared plate can be completely met.

Compared with a pure foaming cement piece, the fireproof integrated plate manufactured by the technical scheme has higher strength, can have thinner volume and is convenient to install on the outer wall and the inner wall of a building. In addition, the cement putty step forms a smooth layer on the corresponding surface of the fireproof integrated plate, so that the surface of the fireproof integrated plate is convenient to be correspondingly treated for decoration and the like compared with a common foamed cement piece, and the fireproof integrated plate also has certain waterproof capability.

The release agent is used in various molding operations of glass fiber reinforced plastics, castings, polyurethane foams and elastomers, injection molded thermoplastics, vacuum foamed sheets and extruded profiles. In molding, other plastic additives such as plasticizers and the like sometimes bleed out to the interface, and a surface-removing agent is required to remove it. The release agent selected by the invention is a material which is convenient for the cement material to be released from the mould.

Wherein, the bulges are made into a honeycomb shape, namely a six-surface shape, or a square shape and the like which are uniformly arranged, and glass fiber with very small heat conductivity or other anti-combustion organic and inorganic fibers are added in the middle. Not only the weight is reduced, the strength is enhanced, but also the heat conductivity coefficient is reduced.
