Abstract
Disclosed reinforced heat-insulation three-dimensional fabric comprises an upper surface layer, a lower surface layer and an intermediate layer arranged between the upper surface layer and the lower surface layer, wherein the intermediate layer comprises spacing fibers and silica aerogel dopped with whisker or/and reinforced short fiber, and multiple intervals formed by arrange of the spacing fibers are filled with the silica aerogel. The three-dimensional fabric provided by the invention not only has good fire resistance, heat resistance and heat insulation performance, but also has good compressive strength, bending strength and tensile strength, is capable of satisfying the application requirements in the fields of fire fighting, industrial heat insulation and the like, and has practicality.
Description
Technical field
The present invention relates to a kind of three dimensional fabric, specifically, relate to a kind of enhancing, heat insulation three dimensional fabric.
Background technology
Three dimensional fabric claims again space fabric, refers to a kind of fabric construction of bilayer, levels fabric and a paraphysis, consists of, and the interval yarn with different-stiffness in the middle of fabric connects.Interval yarn adopts higher terylene or the Polyamide Yarns of counter-bending rigidity conventionally, thereby two superficial layers can be propped up and separated, and forms the intermediate layer with the more air of certain thickness storage.The characteristic of the design feature of space fabric and interval yarn has been given space fabric stable structure and unique physical property, can be widely used in a plurality of fields such as clothes, decoration and industry.
Under heat-flash radiation environment, physical protection is equipped and to heat insulation and mechanical property, is had the occasion of requirement as very important in fire-fighting vest and engine heat-barrier material etc.This class material requirements is not only had to good anti-heat radiation and effect of heat insulation, and have that quality is light, good mechanical performance, the performance such as high temperature resistant and fire-retardant.The three-dimensional spacer fabric that adopts high-temperature fibre to form has good flameproof effect, but its heat-proof quality can reduce along with the increase of interval air layer.SiO
2aeroge has excellent heat-proof quality, but physical property is as very low in bending, compressive strength, has therefore limited its practical application.If bi-material is combined, can avoid above-mentioned shortcoming, but have no at present the fabric report with said structure feature.
Summary of the invention
The problems referred to above and the demand that for prior art, exist, the object of this invention is to provide a kind of enhancing, heat insulation three dimensional fabric, make it not only there is good fire resistance, heat resistance and thermal insulation, but also there is good compression strength, bending strength and tensile strength, to meet the application requirements in fire-fighting, the industry field such as heat insulation.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of enhancing, heat insulation three dimensional fabric, comprise upper surface layer, undersurface layer and be located at the intermediate layer between upper and lower two superficial layers, it is characterized in that: described intermediate layer comprise a paraphysis and doped with whisker or/and strengthen the aerosil of short fiber, described aerosil uniform filling is being arranged in the some intervals that form by a paraphysis.
As a kind of preferred version, described whisker is that crystal whisker of hexa potassium titanate is or/and silica whisker.
As a kind of preferred version, described enhancing short fiber is the basalt fibre of 1～5mm length.
As a kind of preferred version, described between paraphysis be W shape or X-shaped arrangement architecture.
As a kind of preferred version, described between paraphysis select and superficial layer homogeneity long filament.
As a kind of preferred version, described upper and lower two superficial layers are all selected high-temperature fibre.
As further preferred version, described high-temperature fibre comprises at least one in glass fibre, basalt fibre, aramid fiber.
As a kind of preferred version, at upper surface layer or/and be provided with heat-reflective coating on undersurface layer.
Compared with prior art, due to the present invention adopt in intermediate layer by a paraphysis arrange in the some intervals that form uniform filling doped with whisker or/and the aerosil of enhancing short fiber, therefore, make three dimensional fabric provided by the invention not only there is good fire resistance, heat resistance and thermal insulation, but also there is good compression strength, bending strength and tensile strength, the application requirements that can meet fire-fighting, the industry field such as heat insulation, has practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of enhancing provided by the invention, heat insulation three dimensional fabric;
Fig. 2 is the structural representation of another kind of enhancing provided by the invention, heat insulation three dimensional fabric.
In figure: 1, upper surface layer; 2, undersurface layer; 3, intermediate layer; 31, a paraphysis; 32, aerosil; 321, whisker; 322, strengthen short fiber; 4, heat-reflective coating.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is elaborated further:
As depicted in figs. 1 and 2: a kind of enhancing provided by the invention, heat insulation three dimensional fabric, comprise upper surface layer 1, undersurface layer 2 and be located at the intermediate layer 3 between upper and lower two superficial layers, described intermediate layer 3 comprise a paraphysis 31 and doped with whisker 321 or/and strengthen the aerosil 32 of short fiber 322, described aerosil 32 uniform fillings are being arranged in the some intervals that form by a paraphysis 31; Described paraphysis 31 is W shape (as shown in Figure 1) or X-shaped (as shown in Figure 2) arrangement architecture.
As a kind of preferred version, at upper surface layer or/and be provided with heat-reflective coating 4 on undersurface layer, further to reduce heat radiation and surface temperature.
As a kind of preferred version, described whisker is that crystal whisker of hexa potassium titanate is or/and silica whisker; Described enhancing short fiber is the basalt fibre of 1～5mm length; Described paraphysis selected and superficial layer homogeneity long filament; Described upper and lower two superficial layers are all selected high-temperature fibre, such as: glass fibre, basalt fibre, aramid fiber etc.
Because of the present invention adopt in intermediate layer by a paraphysis arrange in the some intervals that form uniform filling doped with whisker or/and the aerosil of enhancing short fiber, make a paraphysis form long and short fiber with whisker together with short fiber and play humidification, and because aerosil has good heat-proof quality and pliability, therefore, three dimensional fabric provided by the invention not only has good fire resistance, heat resistance and thermal insulation, but also there is good compression strength, bending strength and tensile strength, can meet fire-fighting, the application requirements in the fields such as industry is heat insulation, there is practicality.
Finally be necessary to be pointed out that at this; above-mentioned explanation is only for being described in further detail technical scheme of the present invention; can not be interpreted as limiting the scope of the invention, some nonessential improvement that those skilled in the art's foregoing according to the present invention is made and adjustment all belong to protection scope of the present invention.
