Description
Technical Field
The invention relates to the technical field of heat-insulating articles, in particular to a carriage heat-insulating fireproof material.
Background
The carriage may face extreme flame environment during use, such as external combustible combustion environment like gasoline, diesel oil, etc. When the temperature is at such extreme, the carriage needs to be subjected to thermal protection design in order to ensure that the internal equipment is within the normal working temperature range; meanwhile, when the carriage is in a cold environment, the interior of the carriage needs to be insulated so as to ensure normal activities of equipment and personnel; the traditional flame-retardant heat-insulating material usually adopts a material with small apparent density, loose internal structure, high porosity and small water content as a lightweight aggregate, and the lightweight aggregate is combined together by the action of a binder and directly paved on the surface of the inner wall of a carriage to form a heat-insulating layer with a certain thickness, so that the heat-insulating and heat-preserving effects are achieved. Because the structure of traditional insulating layer is loose, mechanical properties such as tensile resistance are not enough, lead to structure weight to increase and take place the condition such as damage even fracture easily when the heat preservation is too thick, and then influence the vehicle and conventionally travel.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the defects in the prior art, the invention provides a carriage heat-insulating fireproof material which can improve the structural strength of the material.
The technical scheme is as follows: in order to achieve the purpose, the heat-insulating fireproof material for the carriage is prepared from the following components in percentage by weight: 20 to 80 percent of pre-oxidized fibers, 25 to 50 percent of low-melting-point PET fibers and 15 to 35 percent of PET fibers; the material has the compression strength of 0.2-0.3 Mpa, the heat conductivity coefficient of 0.045-0.06W/mK and the combustion heat value of 1.9-2.7 MJ/kg.
Further, 20% -80% of pre-oxidized fibers, 25% -50% of low-melting-point PET fibers and 15% -35% of PET fibers are scattered and mixed through stirring equipment, the mixed materials enter main carding equipment after being pre-carded and pre-lapped, and lapping treatment is carried out after the main carding treatment.
Further, the mixed material after the main carding and the lapping treatment is subjected to needle punching to disorder the fiber arrangement direction of the mixed material.
Further, the mixed material is heated by a hot air device to melt the low-melting-point PET fibers in the mixed material.
Has the advantages that: the heat-insulating fireproof material for the carriage can improve the structural strength of the material, and comprises the following technical effects:
1) the fiber arrangement direction of the mixed material is disordered through the needle machine, so that the density and elasticity of the cloth cover are enhanced and firmer;
2) the low-melting-point PET fiber is added, and the material is heated by hot air equipment and then melted, so that the PET fiber and the pre-oxidized fiber are adhered, and the mechanical properties of the material, such as toughness, tensile strength and the like, are further improved.
Detailed Description
The present invention will be further described with reference to the following examples.
The heat-insulating fireproof material for the carriage is prepared from the following components in percentage by weight: 20 to 80 percent of pre-oxidized fiber, 25 to 50 percent of low-melting-point PET fiber and 15 to 35 percent of PET fiber; the material has the compression strength of 0.2-0.3 Mpa, the heat conductivity coefficient of 0.045-0.06W/mK and the combustion heat value of 1.9-2.7 MJ/kg; this material density is lower, and the structure is fluffy slim and graceful, and has higher toughness strength and can buckle, is convenient for adapt to laminating carriage structure, even if there is the dead angle also can make it cover the heat preservation district completely through processing such as cutting down, buckling to heat preservation fireproof material in carriage heat preservation position. The material has low heat conductivity coefficient and low heat value, and the low heat conductivity coefficient can reduce the heat loss in the carriage.
Firstly, scattering and mixing 20-80% of pre-oxidized fibers, 25-50% of low-melting-point PET fibers and 15-35% of PET fibers through stirring equipment, pre-carding and pre-lapping the mixed materials, then feeding the mixed materials into main carding equipment, and lapping the mixed materials after main carding; mixing the required materials according to a ratio to enable the pre-oxidized fiber and the PET fiber to be fully fused, wherein the pre-oxidized fiber has higher carbon content and is subjected to oxidation treatment in the air, so that the pre-oxidized fiber has high temperature resistance to a certain degree; the PET fiber has higher strength and elastic recovery capability, has the function of improving toughness of the material as an auxiliary material, has the characteristic of poorer air permeability, and can improve the heat-insulating property of the material.
The mixed material after the main carding and lapping treatment is subjected to needling to disorder the fiber arrangement direction of the mixed material; when the fiber net is fed into a needle machine, the mixed material is quite fluffy, only a certain strong force is generated by the cohesive force between fibers, but the strong force is poor, when a plurality of felting needles penetrate into the fiber net, the felting hooks on the felting needles can drive the fibers on the surface and the sub-surface of the fiber net to move from the plane direction of the fiber net to the vertical direction of the fiber net, so that the fibers are displaced up and down, and the fibers displaced up and down generate certain extrusion on the fiber net, so that the fibers in the fiber net are close to each other and compressed; the friction force between fibers in the fiber web is increased, the strength of the fiber web is increased, and the density is increased, so that the material forms a fiber web structure with certain strength, density and elasticity.
Heating the mixed material by a hot air device to melt the low-melting-point PET fibers in the mixed material; because the PET fiber components are divided into two materials of normal melting point and low melting point, the low melting point PET fiber is melted after being heated by hot air equipment, and the PET fiber and the pre-oxidized fiber are adhered, so that the mechanical properties of the material, such as toughness, tensile strength and the like, are further improved, and the material has wider adaptability.
Example 1: the heat-insulating fireproof material for the carriage is prepared from the following components in percentage by weight: 60% of pre-oxidized fibers, 25% of low-melting-point PET fibers and 15% of PET fibers; the materials are scattered and mixed by stirring equipment, the mixed materials enter main carding equipment after being subjected to pre-carding and pre-lapping, and are subjected to lapping treatment after being subjected to main carding treatment to finally prepare a cloth cover structure with the thickness of 7 mm; feeding the processed cloth structure into a needle machine for needling treatment and pressing into a thickness of 4mm, finally heating the cloth structure through hot air equipment to enable the low-melting-point PET fibers to reach a melting point, and adhering the fibers after the low-melting-point PET fibers are melted.
The use performance of the compartment heat-insulating fireproof material obtained in the embodiment 1 is subjected to a standardized test, and a commercially available common heat-insulating cloth with the same specification is taken as a comparative example; the results of the tests carried out are shown in the following table:
TABLE 1
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
