Description

Technical Field

[0001] The utility model relates to the field of sponges, in particular to a flame-retardant thermal insulation sponge. Background Art

[0002] The commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. In addition, there are also natural sponges made from sponge animals, most of which are used for body cleaning or painting. In addition, there are three types of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (highly absorbent material without obvious pores) and polyester.

[0003] After searching, a flame-retardant thermal insulation sponge with a publication number of CN211280063U specifically relates to the technical field of thermal insulation sponges, including a sponge body, wherein the top and bottom of the sponge body are respectively fixedly connected with a first puncture-proof layer and a third puncture-proof layer, a first constant temperature layer is fixedly arranged on the top of the first puncture-proof layer, a second puncture-proof layer is fixedly arranged on the top of the first constant temperature layer, a first flame-retardant layer is fixedly arranged on the top of the second puncture-proof layer, a first antibacterial layer is fixedly arranged on the top of the first flame-retardant layer, and a second constant temperature layer is fixedly arranged on the bottom of the third puncture-proof layer. The utility model can enhance the flame retardant performance by providing the first flame-retardant layer and the second flame-retardant layer, and then a plurality of airbags are provided inside the sponge body, so that when the utility model catches fire, the high-pressure inert gas inside the airbags flows out, thereby achieving a fire prevention effect and facilitating use;

[0004] This technology has the effect of preventing fire in the event of a fire, but the surface of the sponge is coated with multiple layers of flame retardant and antibacterial layers. During a fire, the middle layer needs to burn close to the bottom layer to allow the gas in the airbag to flow out, which increases the time required for a fire and poses certain safety hazards. Therefore, a flame retardant thermal insulation sponge is proposed to address the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-Figure 3 As shown, a flame retardant thermal insulation sponge comprises a sponge layer 1; a first thermal insulation layer 2 is attached to the bottom of the sponge layer 1, a second thermal insulation layer 3 is attached to the top of the sponge layer 1, a flame retardant layer 4 is fixedly connected to the top of the second thermal insulation layer 3, a first cooling layer 5 is attached to the top of the flame retardant layer 4, a second cooling layer 6 is attached to the top of the first cooling layer 5, a flame retardant bag 7 is installed between the second cooling layer 6 and the first cooling layer 5, and the flame retardant bag 7 is an air bag, and heptafluoropropane is placed inside, which has a physical fire extinguishing effect;

[0023] During operation, by setting the first thermal insulation layer 2 and the second thermal insulation layer 3 in cooperation, the thermal insulation effect of both sides of the sponge is effectively increased, and the flame retardant layer 4 in the middle has a certain protective effect, reducing the possibility of internal combustion, and at the same time the first cooling layer 5 and the second cooling layer 6 on the surface reduce the entry of external heat to prevent spontaneous combustion, and the flame retardant bag 7 arranged inside the second cooling layer 6 can spray the internal heptafluoropropane around when a fire occurs, which has a certain fire extinguishing effect, and can self-extinguish in the fastest time to slow down the spread of the fire.

[0024] Furthermore, the first thermal insulation layer 2 is made of a mixture of raw materials such as floating beads and brucite fibers, which has the function of forming a closed hydrophobic microporous cavity;

[0025] When working, raw materials such as floating beads and brucite fibers form a closed hydrophobic microporous cavity structure, which can be used as a carrier of phase change materials to ensure the long-term practicality of phase change materials.

[0026] Furthermore, the second thermal insulation layer 3 is made of glass fiber wool, an inorganic non-metallic material with excellent performance;

[0027] At work, glass fiber wool is the most commonly used thermal insulation material. It is made of glass balls as the main raw material and is made through high-temperature melting, wire drawing, weaving and other processes. It is an inorganic non-metallic material with excellent performance.

[0028] Furthermore, the flame retardant layer 4 is an organic halide, which has a good flame retardant effect when used in conjunction with antimony trioxide or phosphide;

[0029] When working, organic halides, mainly bromides, chlorides, halides, commonly used are decabromobiphenyl acid (DBDPO), tetrabromobisphenol A (TBBPA), brominated polystyrene (BPS) and chlorinated paraffin and chlorinated polyethylene; halides are often used in conjunction with antimony trioxide or phosphide. Organic halides are a flame retardant with a very good flame retardant effect. We only need to add a little to delay or block combustion. It is a commonly used economical and applicable flame retardant layer 4.

[0030] Furthermore, the first cooling layer 5 is a photocatalyst coating, which has a uniform liquid diffusion effect;

[0031] When working, photocatalysts have the property of absorbing a large amount of water when exposed to sunlight. If you apply a material mixed with photocatalysts on the outer walls and roofs of buildings and then pour water on them, the water will spread thinly and evenly, just like sprinkling water on the building. When the water evaporates, it will take away the heat, and the surface temperature of the building will be greatly reduced.

[0033] When working, nanotechnology is used to make a variety of inorganic raw materials form compact glass bubble-type particles. The infrared reflectivity of this complete hollow insulation layer reaches 80% and the ultraviolet reflectivity reaches more than 90%, thereby reducing the heat energy of solar radiation and preventing spontaneous combustion.

[0034] Working principle: The coordinated use of the first thermal insulation layer 2 and the second thermal insulation layer 3 effectively increases the thermal insulation effect on both sides of the sponge, and the flame retardant layer 4 in the middle has a certain protective effect, reducing the possibility of internal combustion, and at the same time the first cooling layer 5 and the second cooling layer 6 on the surface reduce the entry of external heat to prevent spontaneous combustion, and the flame retardant bag 7 arranged inside the second cooling layer 6, when a fire occurs, the internal heptafluoropropane is sprayed around, which has a certain fire extinguishing effect, and can self-extinguish in the fastest time, slowing down the spread of the fire.
