It is an object of the invention to provide a kind of preparation method of the foam glass with compared with high-heat resistance shock resistant, on overcoming
The defect of prior art presence is stated, the present invention reduces solid waste using two kinds of glass wastes, with certain environmental-protection function,
The foam glass prepared simultaneously has compared with high-heat resistance shock resistant, and pore size is uniform.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：
A kind of preparation method of the foam glass with compared with high-heat resistance shock resistant, comprises the following steps：
Step one：Use 74.5wt.% high borosilicate cullet and 24.5wt.% flat boards cullet for primary raw material, add
Plus 1wt.% carborundum powders are as foaming agent, batch mixing is then carried out using tumbling ball mill and obtains mixed powder；
Step 2：PVA is added to mixed powder to be granulated, then use half is dry-pressing formed obtains base substrate, and base substrate is existed
Blowing temperature is warming up to after 120 DEG C of insulation 12h and carries out high temperature foaming, cooling can be obtained with compared with highly heatproof and shockproof after foaming terminates
The foam glass of property.
Further, the granularity of carborundum foaming agent is 3.5 μm in step one.
Further, briquetting pressure is 2.5 tons in step 2.
Further, base substrate size is 30 × 30 × 20mm in step 23。

Compared with prior art, the present invention has following beneficial technique effect：
The present invention prepares foam glass using high borosilicate cullet as primary raw material, and high borosilicate cullet has compared with low-heat
The coefficient of expansion, can assign product compared with high-heat resistance shock resistant and thermal-shock resistance.But viscosity is big at high temperature for high borosilicate cullet,
It is difficult foaming, thus the present invention adds a certain amount of flat board cullet and changes melt high temperature viscosity and foamed, and can reach resource
Efficiently utilize, energy-conserving and environment-protective and reduce the purposes such as cost, with huge social and economic benefit；The foam glass prepared
With compared with high-heat resistance shock resistant, while pore size distribution is narrower, size uniform.
