example 1

[0026]According to the mass ratio of 1:1, put the basalt and quartzite into the stone crusher and crush them for 10 minutes to get the rough rocks. Add the silane coupling agent KH-560 to the coarse rocks and mix for 16 minutes. After stirring, put them into sacks. Put the sack at the bottom of the fermenter, mix peanut oil and biogas slurry into the fermenter at a mass ratio of 1:2, wait until the sack is completely submerged, then seal the fermenter, and ferment at a temperature of 35°C for 10 days until the end of fermentation Finally, take out the sack, put the rough rock in the sack into a ball mill and grind through a 200-mesh sieve, collect the sieved powder, and then get the self-made modified sieved rock powder for subsequent use. The mass fraction is 3:1 according to the mass ratio. Mix and stir 30% water glass and silane coupling agent KH-792 for 6 minutes to obtain modified water glass, weigh 16g of sodium fluorosilicate and grind it through a 100 mesh sieve, collec...

Abstract

The invention discloses a preparation method of a high-compressive-strength heat-proof foam glass plate and in particular relates to the technical field of preparation of building materials. The preparation method is characterized in that a silane coupling agent is used for modifying basalt and quartzite, and the modified basalt and quartzite are put into vegetable oil and biogas slurry microorganisms to be blended and fermented, so that compatibility between rocks and high polymers is enhanced, and homogeneous dispersion strength of the rocks and high polymers is also improved; a water-soluble silane coupling agent, sodium fluorosilicate and glass fibers are added into resin, so that compressive strength of the foam glass plate is further improved; and by adding boric sludge, fly ash, modified aluminum hydroxide and boric acid, viscosity of glass melt is further improved, compressive strength performance and heat resistance of the foam glass plate are obviously improved, the boric acid not only can accelerate melting but also can improve foam structures, so that foams are uniform and small, and the compressive strength of the foam glass plate can be beneficially improved.

Description

[0001] Technical Field The present invention relates to the technical field of building material preparation, in particular to a method for preparing a heat-resistant foam glass plate with high compressive strength. Background technique [0002] Foam glass plate is an inorganic non-metallic glass material made of cullet, foaming agent, modifying additive and foaming accelerator, etc., which are finely pulverized and uniformly mixed, then melted and foamed at high temperature, and annealed. Foreign countries began to develop it in the 1930s, and domestic introduction and development began in the late 1980s. Because of the independent cell structure, the volume density is very small, the thermal conductivity is small, it is 0.052w / m.k at room temperature, and the thermal insulation performance is good, but the compressive strength is small (average 0.7Mpa), and the flexural strength is small (average 0.5Mpa), so It is mainly used as a thermal insulation component of composite wa...
