Problems solved by technology

The synergistic effect produced by adjusting the formula and the different proportions of various flame retardants can improve the flame retardant properties of sponge products and reduce the impact of flame retardants on the physical properties of sponge products, but it is still an unsolved problem. During long-term use, the migration and precipitation of flame retardants, and the performance of soft polyurethane foam products have changed.

Abstract

The invention discloses a breathable sponge mattress with an antibacterial and flame-retardant function. The mattress is made of an opened polyurethane sponge substrate and an antibacterial flame-retardant layer wrapped on the surface of the opened material of the substrate, the antibacterial flame-retardant layer makes the flame retardant and anti-mite properties of the mattress be greatly improved, the flame retardant effect is good, the smoke density is low, there is no smoke and toxicity, the flame retardant grade can reach UL94 V-0 grade, the anti-mite effect is good, and the repellent rate reach 70% or more; a mixture of liquid carbon dioxide and liquid nitrogen is used as a foaming agent, the foaming effect is good, the addition of a vulcanization activator further improves the foaming effect, and a prepared sponge has excellent gas permeability.

Description

technical field [0001] The invention belongs to the technical field of sponge products, and in particular relates to a breathable sponge mattress with antibacterial and flame-retardant functions. Background technique [0002] Most mattresses on the market are made of non-woven fabrics, sponges and springs. Although this kind of mattress is comfortable and durable, it is not suitable for crew members on board, especially for ships operating in offshore oil fields, because they are too close to oil products, so It is required that the used mattress must have flame retardant function, but the materials used in the existing household mattresses are all combustible materials, so they do not have flame retardant effect. [0003] Traditional flame retardant materials widely use halogen-containing polymers or flame-retardant mixtures composed of halogen-containing flame retardants. However, once a fire breaks out, due to thermal decomposition and combustion, a large amount of smoke...
