Description
Technical field
The present invention relates to Silica hydrogel preparing technical field, more particularly to a kind of inorganic polymer Silica hydrogel and its preparation side
Method.
Background technology
Foam glass is a kind of thermal insulation of superior performance(Cold insulation), sound absorption, moistureproof, fireproof light high-strength building material and
Ornament materials, is subzero 196 degree to 450 degree using temperature range, A level does not fire the same life-span with building, moisture permeable coefficient is almost
0.Although other novel heat insulation materials emerge in an endless stream, foam glass is so that it is permanent, security, high reliability are exhausted in low-heat
The fields such as edge, tidal defense engineering, sound absorption are in occupation of increasingly consequence.Its production is waste solid Reuse of materials, is
Environmental protection simultaneously obtains the example of abundant economic interests.
When using, required adhesive glue requires to reach waterproof foam glass, anti-corrosion, heat-insulation and heat-preservation, and high-performance is super early
By force, high temperature resistant, the characteristic of freeze thawing resistance.At present, the sealant using in foam glass bonding industry mainly has diplobiont system, respectively
It is curing system and non-curing systems.
The material that non-curing systems use is thermoplastic material, such as thermoplasticity one-component hot melt butyl material.Such
Sealant meeting deliquescing in heating, prepared glass assembly will misplace when bearing heavy burden or deform, and this shortcoming is in temperature
Even more serious when higher.Therefore, it is difficult to by wanting to intensity and temperature with the foam glass assembly that hot melt butyl sealant produces
The industrial standard asking strict detects, can be only applied to less occasion of bearing a heavy burden.Additionally, such fluid sealant must be more than 100 DEG C
Temperature could apply, such operation temperature easily makes workmen injured, also increases production cost.
Curing system is divided into one-component system and bicomponent system, and the material of use is thermosetting or the material of chemical solidity
Material, such as liquid polysulphides, the material such as polyurethane and organosilicon.Curing system the more commonly used at present is typically all bi-component
They, including basic ingredient and curing agent, are mixed when using, solidify by system.Bicomponent system typically requires to set
Mixing ratio, and need normal temperature mixing at the scene.Then, by with the catalyst reaction infiltrated or reaction of moisture, solidification is slow,
Need assembly to be fixed on several hours or even a couple of days on equipment, wait sealant hardening.Simultaneously because foam glass have not close
The characteristic of water, the fluid sealant of curing system of the prior art is also not suitable for the bonding of foam glass.Such double-component system
Complicated using step, cure cycle is long, and construction cost is higher.
Therefore it provides a kind of foam glass special glue with superperformance is to solve in the urgent need to those skilled in the art
Technical problem.
