Problems solved by technology

Microcrystalline plates produced from industrial waste such as copper tailings and metallurgical slag have been used in the construction field. However, due to the single color (mostly black) and large color differences in batches, and the complexity of raw material sources The quality and yield of finished products are more difficult to control, and it has not been popularized and applied in large quantities.
Foam glass has not been widely used because of its low strength, easy damage and easy to burst during heat treatment.

specific Embodiment approach

[0040] Specific embodiments: a composite foam glass-ceramic, which includes toughened glass, characterized in that: foamed glass-ceramic is compounded on the toughened glass.

[0041] The foamed glass-ceramic is formed by sintering after soaking the foamed plastic with communicating holes into the glass slurry.

[0042] The foamed micro-glass is formed by mixing ceramsite and glass slurry, spreading it into boards and then sintering.

[0043] The foamed glass-ceramics is formed by mixing polystyrene particles and glass slurry, spreading them into plates and then sintering them.

[0044] The glass slurry is a mixture of cullet and thick additives.

[0045] The cullet is formed by melting industrial waste, and the thick additive is carboxymethyl cellulose (CMC).

[0046] A method for making composite foam glass-ceramic, characterized in that it comprises the steps of:

[0047] Making glass slurry: Grinding cullet with a particle size of (100-300) mesh: introducing a nucleatin...

Embodiment 1

[0070] Embodiment 1: Grinding the cullet to make the particle size reach 120 mesh (it can be between 100 mesh and 300 mesh). Introduce a nucleating agent, mix thick additives such as carboxymethyl cellulose (CMC) or 107 glue or pulp liquid or starch liquid with finely ground broken glass, add water to make a thick shape, and form a glass slurry with a solid content of 80 %, (the solid content can be between 65% and 90%), and then the foamed plastic plate with communicating holes is immersed in the glass slurry. After the connecting hole is filled with glass slurry, take it out and dry it at 70°C. Send it into a sintering furnace for sintering, the sintering temperature is 800°C (the sintering temperature can be between 400°C and 1000°C), and the time is 3 hours (the time can be between 1 hour and 5 hours). After slowly cooling down, foamed glass-ceramic is formed. The foam glass and tempered glass are then bonded together with an adhesive to form composite foam glass-ceramic...

Embodiment 2

[0071] Embodiment 2: Grinding the cullet to make the particle size reach 120 mesh (it can be between 100 mesh and 300 mesh). Introduce a nucleating agent, mix thick additives such as carboxymethyl cellulose (CMC) or 107 glue or pulp liquid or starch liquid with finely ground broken glass, add water to make a thick shape, and form a glass slurry with a solid content of 80 % (solid content can be between 65% and 90%). Mix ceramsite and glass slurry and spread it in the mold to make a slab. The volume ratio of ceramsite and glass slurry is: 4 to 6 {volume ratio between (2-5)~(5-8) room available). Dry it at a drying temperature of 70°C. Send it into a sintering furnace for sintering, the sintering temperature is 1000°C (the sintering temperature can be between 800°C and 1200°C), and the time is 3 hours (the time can be between 1 hour and 5 hours). After slowly cooling down, foamed glass-ceramic is formed. The foam glass and tempered glass are then bonded together with an adhe...

Abstract

A composite foam pyroceram as engineering material is composed of strengthened glass and foam pyroceram attached to said strengthened glass. It is prepared through grinding broken glass, adding carboxymethyl cellulose, stirring, immersing foam plastic in it until its communicated pores is full of glass slurry, or mixing haydites with the glass slurry and spreading, or mixing polyctyrene particles with the glass slurry and spreading, baking at 40-90 deg.C, sintering at 400-1000 deg.C for 1-5 hrs, cooling, and combining it with strengthened glass. Its advantages are high strength and high heat and sound isolating effect.

Description

[0001] Technical field: [0002] The invention relates to an engineering material and a co-manufacturing method, in particular to a composite foam glass-ceramic and a manufacturing method thereof. Background technique: [0003] Glass-ceramics are polycrystalline solids produced by the controlled crystallization of glass. The meaning of microcrystallization refers to nucleating the nucleating agent introduced into the glass through an appropriate heat treatment system and triggering crystal growth to form microcrystals. Glass-ceramics are widely used in mechanical engineering, aerospace engineering, nuclear engineering, food, medicine, optics and other fields according to their unique properties. Microcrystalline plates produced from industrial waste such as copper tailings and metallurgical slag have been used in the construction field. However, due to the single color (mostly black) and large color differences in batches, and the complexity of raw material sources The quali...
