Problems solved by technology

The deck covering is multi-layered and complicated, and the construction period is long, which leads to the extension of the entire repair period; in addition, the large amount of materials used in the whole ship reduces the loading capacity of the ship and the stability of the ship's shipping; before the construction of the single-layer structure d

Embodiment 1

[0017] The lightweight fire resistant deck covering according to this embodiment includes an inorganic binder and a covering body. Wherein the inorganic binder is composed of 45wt% carbon silicon alumina and 55wt% sodium silicate. The dressing main body is composed of 32wt% filler, 52wt% coagulant and 14wt% accelerator liquid.

[0018] In this example, the filling material is made of 85% shale pottery sand, 6.5% vermiculite and 8.5% steel fiber. Among them, the particle size of shale pottery sand is 3-5mm, and the density is 500kg / m 3 About; the particle size of vermiculite is 2~3mm; the length of steel fiber is 28~32mm, and the tensile strength is greater than or equal to 600N / mm 2 , the radial twist is greater than or equal to 20 degrees. The coagulant is made by mixing 90wt% of 42.5 grade Portland cement, 5% of perlite powder and 5% of silicon powder; the accelerator liquid is composed of 3% of water reducer sodium naphthalenesulfonate formaldehyde condensate, 4% of phosp...

Embodiment 2

[0021] The lightweight fire resistant deck covering according to this embodiment includes an inorganic binder and a covering body. Wherein the inorganic binder is composed of 43.5wt% carbon silicon alumina and 56.5wt% sodium silicate. The dressing main body is composed of 35wt% filler, 52wt% coagulant and 13wt% accelerator liquid.

[0022] In this example, the coagulant and the accelerating liquid are the same as in the examples. The filling material is made of 87.5% shale pottery sand, 6% vermiculite and 6.5% steel fiber. Among them, the particle size of shale pottery sand is 3-5mm, and the density is 500kg / m 3 About; the particle size of vermiculite is 2~3mm; the length of steel fiber is 28~32mm, and the tensile strength is greater than or equal to 600N / mm 2 , the radial twist is greater than or equal to 20 degrees.

Abstract

The invention relates to a light refractory deck covering, which comprises an inorganic binder and a covering main body; and on the basis of the total weight of the covering main body, the covering main body comprises the following components: 30 to 35 percent of filler, 49 to 56 percent of coagulation accelerator and 12 to 16 percent of promoting liquid, wherein the coagulation accelerator consists of 85 to 93 percent of silicate cement, 3 to 8 percent of crushed crude pearlite and 4 to 7 percent of silica powder; and the promoting liquid consists of 2.5 to 5 percent of water reducer, 3.5 to 5 percent of phosphoric acid and 89.5 to 94.5 percent of water. The inorganic binder is used for reinforcing the adhesive force of the covering main body and a steel deck; a process for pre-welding clamps is innovated; a working procedure for arranging and coordinating work-type spanning personnel in the construction is eliminated; and possible inconvenient construction and unsafe factors caused by pre-welding the clamps are avoided. In addition, the light refractory deck covering can be constructed and formed at one time on spot; the construction period is only 2 to 3 days; and the covering thickness can be reduced to 40mm so as to greatly reduce the weight of materials covered on the whole ship.

Description

technical field [0001] The present invention relates to a deck covering. Background technique [0002] According to the requirements of the SOLAS Convention on Life at Sea and its ship regulations, on the decks of marine engineering and ships, covering layers with different fire protection levels must be laid, which are deck coverings. It is divided into non-flammable deck base covering and fire-resistant deck covering. From the perspective of the development direction of deck coverings in various countries in the world, in addition to requiring the covering to meet the specification requirements of ships, the covering also requires light bulk density, simple structure and convenient construction. [0003] In the prior art, fire-resistant deck coverings mainly have a multi-layer structure and a single-layer structure. In the multi-layer structure, the first layer of bottom material is laid, the second layer of waterproof layer and reinforcing material is laid, and the thir...
