A60-level lightweight refractory deck composition

Abstract

The invention provides an A60-level lightweight refractory deck composition, comprising at least one component A and component B, wherein the mass ratio of the component A to the component B is (1 to 6) to (1 to 8); the component A is neoprene latex; the component B is prepared from ordinary silicon 42.5 cement, large ceramsite, small ceramsite, large vermiculite and small vermiculite; the grain size of the large ceramsite is 2-5mm; the grain size of the small ceramsite is 0.5-2mm; the grain size of the large vermiculite is 2-4mm; the grain size of the small vermiculite is 0.2-2mm; and the component B contains the ingredients by weight ratio of 50-55% of ordinary silicon 42.5 cement, 20-25% of large ceramsite, 5-10% of small ceramsite, 14-20% of large vermiculite and 5-10% of small vermiculite. The A60-level lightweight refractory deck composition has good lightness, compressive property, fracture resistance and shock resistance, and can effectively prevent sound transmission and heat conduction; and the fire resistance can achieve A-60 level.

Description

technical field [0001] The invention relates to a dressing, in particular to an A60 grade light fireproof deck dressing for ships. Background technique [0002] Deck covering is a covering material laid on the deck of a ship. It has properties such as heat insulation, noise reduction, anti-rust, and anti-skid. At present, the commonly used latex-type deck covering mainly uses latex and cement as the main raw materials. This kind of dressing has good fire resistance. , impermeability, impact resistance, can effectively isolate noise and heat conduction, and it has good adhesion and waterproof, will not produce cracks, but the composition of the existing latex-type deck coverings is relatively complicated, which improves the quality of the product. The cost reduces the economic benefit of the production enterprise, and the proportion of the deck is relatively large, causing a large part of unnecessary load to the ship, increasing the self-weight of the ship, affecting the spee...

[0002] Deck covering is a covering material laid on the deck of a ship. It has properties such as heat insulation, noise reduction, anti-rust, and anti-skid. At present, the commonly used latex-type deck covering mainly uses latex and cement as the main raw materials. This kind of dressing has good fire resistance. , impermeability, impact resistance, can effectively isolate noise and heat conduction, and it has good cohesiveness and water resistance, and will not produce cracks, but the composition of the existing latex-type deck coverings is relatively complicated, which improves the quality of the product. The cost reduces the economic benefit of the production enterprise, and the proportion of the deck is relatively large, causing a large part of unnecessary load to the ship, increasing the self-weight of the ship, affecting the speed and load capacity of the ship, and Traditional deck coverings contain asbestos, which seriously affects the environment. Therefore, there is an urgent need for an environmentally friendly latex deck covering that is simple to produce and process, economical and affordable, and has a lighter specific gravity.
