Problems solved by technology

A-60 grade deck covering is the covering that is laid on the key parts of the ship where the fire protection requirements are particularly high. It not only needs to be fire-resistant, heat-insulated, smoke-resistant, and corrosion-resistant, but due to its large laying thickness, the lighter the weight after laying, the better. , the original use of yellow sand and gravel concrete as the surface layer, although various properties meet the requirements, but its capacity is large

Embodiment 1

[0015] A production process for a lightweight floating fire-resistant deck covering, comprising the following steps:

[0016] (1) Add 92% of 32.5 grade composite Portland cement and 8% of silicon powder into a large-scale weightless mixer and mix and stir for 45 minutes to obtain the accelerator powder;

[0017] (2) 30% of 2-8mm pottery sand and 70% of 4# quartz sand are evenly mixed to obtain filling aggregate;

[0018] (3) At the site where laying is required, pour 42% of the above-mentioned coagulation-accelerating powder and 58% of the above-mentioned filling aggregate into the mortar machine and stir evenly, and each set is mixed with 38%-43% of the mass of the coagulation-accelerating powder in proportion. Water is stirred, and mixed into a thick mud to obtain a light dressing for the surface layer; in the present invention, the percentages involved are mass percentages;

[0019] (4) Use ceramic cotton as the bottom layer, lay a layer of PE waterproof film on the bottom...

Abstract

The invention discloses a process for producing a light floating fire-resistant deck covering. In the light floating fire-resistant deck covering, ceramic wool is used as a bottom layer, a layer of waterproof paper is paved on the bottom layer, a reinforcing mesh is paved on the waterproof paper, and a surface layer light covering is paved on the reinforcing mesh; and the surface layer light covering is formed by mixing coagulant powder and a filling aggregate. The light floating fire-resistant deck covering has the high fire-resistant and floating performance, and is elastically separated from a steel plate, so structural noise and vibration can be reduced effectively; and the light floating fire-resistant deck covering has the high effects of sound insulation and heat insulation, and is suitable to be paved on A-60 level decks of machine locations, activity places, control rooms and the like of ships.

Description

technical field [0001] The invention relates to a manufacturing method of a lightweight floating fireproof deck covering. Background technique [0002] As a dressing for ships, different types of dressings must be used according to different needs. A-60 grade deck covering is the covering that is laid on the key parts of the ship where the fire protection requirements are particularly high. It not only needs to be fire-resistant, heat-insulated, smoke-resistant, and corrosion-resistant, but due to its large laying thickness, the lighter the weight after laying, the better. , originally used yellow sand and gravel concrete as the surface layer, although various properties meet the requirements, but its capacity is large. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to provide a production process for a lightweight floating fire-resistant deck covering. [0004] The technical solution adopted in the present invention is: a pr...
