Problems solved by technology

[0002] As we all know, inorganic polymers are a new subject in recent years. Aluminosilicate polymers are a kind of inorganic polymers. They have good high temperature resistance, flame resistance and high temperature without releasing toxic gases. They are widely used in construction and refractory materials. However, due to the low molecular weight of the aluminosilicate polymer itself, the mechanical properties of the aluminosilicate polymer produced by the existing method are poor, and the bending strength is only 4.2~6.5MPa, and the performance It is brittle fracture, which restricts its application range
