preparation example Construction

[0036] The preparation method of described fireproof brick is:

[0037] (1) preparing calcium silicate hydrate;

[0038] (2) obtain mixed material after described calcium silicate hydrate, glass fiber and water are mixed uniformly;

[0039] Among them, the mixing temperature is 20-90°C. Since glass fiber and calcium silicate hydrate are fine fiber substances, their viscosity in water is relatively high. Raising the mixing temperature can improve the uniformity of the mixing. Preferably, the mixing temperature It is 60-90°C.

[0040] (3) Separating the solid and liquid from the mixed material, pressing it into a plate, and drying to obtain the finished fireproof brick.

[0041] Wherein, the pressure during pressing is 20-60MPa, and the pressure maintenance time is 5-120min.

[0042] Preferably, the preparation method of described calcium silicate hydrate is:

[0043] (1) mixing red mud, coal ash, silicon dioxide, and water to obtain a mixed slurry;

[0044] Wherein, the co...

Embodiment 1

[0051] The present invention provides an elevator, including a car; the car includes a car wall, and the car wall includes an inner wall plate and an outer wall plate; a hollow structure is formed between the inner wall plate and the outer wall plate, and the hollow structure is equipped with There are first fireproof bricks and second fireproof bricks; the first fireproof bricks and second fireproof bricks are bonded to the inner wall panels and outer wall panels through refractory sealant; by adding lightweight refractory bricks in the car wall space, the The elevator has a fireproof function without increasing the weight of the elevator.

[0052] Preferably, the thermal conductivity of the first fireproof brick is greater than that of the second fireproof brick; the first fireproof brick is close to the inner wall, and the second fireproof brick is close to the outer wall. When a fire breaks out, the outer wall of the car and the inner wall of the car are heated differently...

Embodiment 2

[0057] Wherein, calcium silicate hydrate is made by following method:

[0058] (1) Mix red mud, coal ash, silica, and water to obtain a mixed slurry; wherein, the mass ratio of red mud to coal ash is 1:1; the total mass of coal ash and red mud to the mass of silica The ratio is 1:1, and the liquid-solid ratio of the mixed slurry is 30:1mL / g.

[0059] (2) Put the mixed slurry into the reaction kettle, carry out hydrothermal reaction, after the reaction, filter, wash and dry to obtain calcium silicate hydrate. Wherein, the hydrothermal reaction temperature is 300° C., and the reaction time is 1 h.

Abstract

The invention discloses an elevator. The elevator comprises a car, wherein the car comprises a car wall, and the car wall comprises an inner wall plate and an outer wall plate; a hollow structure is formed between the inner wall plate and the outer wall plate, and a first fireproof brick and a second fireproof brick are arranged in the hollow structure; the first fireproof brick and the second fireproof brick are bonded with the inner wall plate and the outer wall plate through fire-resistant sealing glue; and the first fireproof brick is prepared from the following raw materials of, in partsby weight, 50-70 parts of hydrated calcium silicate, 5-20 parts of quartz, 5-20 parts of kaolin, and 5-30 parts of glass fiber, wherein the hydrated calcium silicate is a mixture of a hard silicon calcium stone and a tobermorite, and the mass ratio of the hard silicon calcium stone to the tobermorite is 3-5 : 5-7. According to the elevator and the preparation method thereof, the mixture of the hard silicon calcium stone and the tobermorite with excellent heat stability is adopted to serve as a main fireproof component, the fireproof bricks with the fire-resistant temperature ranging from 800 DEG C to 1000 DEG C are prepared to prevent the fire effectively, so that the safety of passengers are guaranteed.

Description

technical field [0001] The invention belongs to the field of ceramic tile preparation, in particular to an elevator and a preparation method thereof. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take advantage of people or carry goods. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. [0003] Ordinary elevators generally do not have fire protection measures, which may easily lead to safety accidents in the event of a fire. In recent years, some companies have also conducted research on it. Patent application CN201510840217.8 discloses a fireproof ...
