Abstract

The invention provides a high-efficiency heat-insulated glass cotton felt structure which is characterized by being formed by combining multiple layers of ultrathin glass cotton felts with multiple layers of silicon dioxide aerogel, wherein the number of layers of the glass cotton felts is one more than that of the silicon dioxide aerogel. Due to the layer-shaped felt structure, a blocking effect on heat flow transmission can be achieved; due to the nano-micropores of the aerogel, the heat conduction coefficient is reduced to a certain extent and the heat insulation performance of the cotton felt is improved.

Description

A kind of effectively insulating blanket of glass wool structure
Technical field
The present invention relates to a kind of blanket of glass wool structure, particularly a kind of effectively insulating blanket of glass wool structure.
Background technology
Blanket of glass wool is that mineral wool applies adhesive, and the felt-like material of heating cure moulding has and has good resilience, heat insulating effect excellence, is widely used in architecture indoor, sound-attenuating system, the vehicles, refrigeration plant, the damping of household electrical appliance, sound absorption, noise reduction process, effect is very good.But for the application of high-end field, need to there is lighter unit weight, possesses efficient heat-proof quality simultaneously, reach this performance requirement, must transform the structure of cotton felt, the use of aerosil has improved the structure of cotton felt to a certain extent, has improved the serviceability of cotton felt simultaneously.
Aerosil has nano-porous structure, makes it at aspects such as calorifics, optics, acoustics, show as unique character.General aerosil density is lower, has special porous network structure, and porosity is more than 90%, most of gas cell distribution is below 50nm, be less than the mean free path 70nm of air molecule, between air molecule, be difficult to bump, there is lower thermal conductivity factor.The preparation method of aerogel composite is mainly divided into two classes at present, is respectively gel molding in integral and grain forming method.For gel molding in integral, in sol-gel process, introduce wild phase, finally obtain Monolithic aerogel composite; For grain forming method, the nano-hole aerogel particle powder preparing is added in wild phase and binding agent, by mold pressing or moulding by casting, make the complex of post forming.
The present invention designs a kind of blanket of glass wool and aerosil laminar composite, there is no between layers obvious border, the effect hindering is played in the existence of layer structure to the propagation of hot-fluid, the simultaneously nanometer level microporous thermal conductivity factor that reduced to a certain extent of aeroge, has improved the heat-proof quality of cotton felt.
Summary of the invention
Object of the present invention is intended to overcome the deficiencies in the prior art, and a kind of effectively insulating blanket of glass wool structure is provided.
For the technical scheme that realizes object employing of the present invention is: a kind of effectively insulating blanket of glass wool structure is provided, has it is characterized in that this structure is combined by Multilayer ultrathin blanket of glass wool and aerosil; The number of plies of blanket of glass wool is 2~6, and thickness in monolayer is 0.5~5mm; The number of plies of aerosil is that the number of plies of blanket of glass wool subtracts one, and thickness in monolayer is 0.05~1mm; Aeroge is distributed in the gap of blanket of glass wool, and between two-layer cotton felt, content is higher, at cotton carpet veneer inside gradient, distributes, and aeroge accounts for product gross weight 2~8%.Aerogel particle is of a size of 10~50nm.
The present invention compared with prior art, has the following advantages:
(1) in a kind of effectively insulating blanket of glass wool structure, adopt the structure of cotton felt and aerosil layering stack, this structure has not only been improved the heat-proof quality of material greatly, has improved the mechanical property of material simultaneously, has expanded the scope of application of material.
(2) in a kind of effectively insulating blanket of glass wool structure, utilization aerosil forms the structure being layering, nanometer level microporous in aeroge, has reduced the overall thermal conductivity of cotton felt.
