Problems solved by technology

Since the compressive strength of traditional cement is less than 50MPa, it is not suitable for occasions with special requirements for pressure resistance
On the other hand, as a common solid waste, waste glass is mainly reused through remelting and smelting, which not only requires strict sorting procedures, but also consumes a lot of energy and causes secondary pollution during the smelting process, so it is green and environmentally friendly. Reuse issues need to be further resolved
Since waste glass contains a certain amount of silicon-aluminum components, it can theoretically be used as a raw material for the preparation of geopolymers, but there is no relevant report on its practical application.

Abstract

The invention discloses a high-strength polymer material and a preparation method thereof on the base that waste glass is taken as a raw material. The preparation method comprises the following steps of: after mechanically processing cleaned waste glass to a certain particle diameter, uniformly mixing and stirring the waste glass with an alkaline excitation agent solution according to a certain proportion; loading the mixture into a mould; after vibrating the mixture on an electric vibration platform for a certain time, transferring the mixture into a constant-temperature curing box; and demoulding after curing the mixture between room temperature and 60 DEG C for 24 h, thus obtaining the high-strength polymer material by curing to predetermined age under a certain temperature. Compared with the traditional silicate cement material, the polymer material prepared by the invention has extremely good mechanical property; the compressive strength for 7 days is beyond of 43.58 MPa; and the compressive strength for 28 days is maximally up to 119.41 MPa.

Description

[0001] technical field [0002] The invention relates to an inorganic polymer material, in particular to a high-strength glass base polymer and a preparation method thereof. Background technique [0003] Geopolymers are a kind of inorganic polymer materials with amorphous three-dimensional network silicon-oxygen tetrahedron and aluminum-oxygen tetrahedron structures, which have some advantages of both inorganic materials and organic polymers. Since the compressive strength of traditional cement is less than 50MPa, it is not suitable for occasions with special requirements for pressure resistance. On the other hand, as a common solid waste, waste glass is mainly reused through remelting and smelting, which not only requires strict sorting procedures, but also consumes a lot of energy and causes secondary pollution during the smelting process, so it is green and environmentally friendly. The reuse problem needs to be further solved. Because waste glass contains a certain amo...
