Problems solved by technology

At present, the common measure to prevent the spread of flames and protect the safety of structures on ships is to coat the surface of the steel plate with a layer of protective thin or ultra-thin fireproof coatings. However, the existing fireproof coatings have insufficient flame retardancy and short fire resistance time. Due to The steel plate has strong thermal conductivity, and there are a lot of combustibles such as oil in some cabins on the ship, such as the engine room. The fire-resistant time of the existing refractory materials is greatly shortened, which is not conducive to fire fighting

Abstract

The invention discloses a nano-composite material applied in ship manufacturing, wherein the nano-composite material comprises the following raw materials by the weight percentage: 30-45% of epoxy resin, 10-15% of organosilicone resin, 25-45% of modified nano-bentonite, 5-8% of maleic anhydride, 6-10% of 1,5-naphthalene diamine, 1.5-3% of zinc stearate, and 5-10% of sodium hydroxymethyl cellulose.Nano-bentonite is activated, impurities in a clay structural layer are removed, and pores of clay are degraded; with use of a solution intercalation method, an organic phosphorus flame retardant is intercalated into lattices of nano-bentonite layers, and the modified nano-bentonite having a flame retardant effect is obtained; the modified nano-bentonite has a large specific surface area, and easily adsorbs monomer maleic anhydride and 1,5-naphthalene diamine, so the contact surface of addition polymerization reaction is increased, and the reaction efficiency is improved; after the modified nano-bentonite is molten and combined with other components, the nano-composite material having high flame retardant and high temperature resistant performance is obtained, and the ability of the flameretardancy of epoxy resin is improved.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a nanocomposite material used in shipbuilding. Background technique [0002] Ship engine room and crew living quarters are key areas for fire prevention, and fire accidents are prone to occur during ship operation, and the marine climate is easy to spread fire. At present, the common measure to prevent the spread of flames and protect the safety of structures on ships is to coat the surface of the steel plate with a layer of protective thin or ultra-thin fireproof coatings. However, the existing fireproof coatings have insufficient flame retardancy and short fire resistance time. Due to Steel plates have strong thermal conductivity, and there are a lot of combustibles such as oil in some cabins on ships, such as engine rooms. The fire-resistant time of existing refractory materials is greatly shortened, which is not conducive to fire fighting. Contents of the inve...
