Micro-crystallizing glass-ceramic composite board and producing method thereof

Abstract

The invention discloses a minicrystal glass-ceramic composite plate and a production method. The minicrystal glass-ceramic composite plate is compounded by a minicrystal glass surface layer and a ceramic core layer; the minicrystal glass comprises the compositions measured in weight: 50 to 68 portions of SiO2, 3 to 10 portions of Al2O3, 20 to 38 portions of CaO, 3 to 12 portions of R2O (Na2O+K2O+Li2O), 0 to 3 portions of B2O3, and 0 to 12 portions of MgO. On the precondition of ensuring the process performance and crystallization performance and appearance decorated effect of product, the invention has no BaO and ZnO compositions, thus obviously reducing the cost of the raw material of minicrystal glass-ceramic composite plate.

Description

technical field

[0001] The invention relates to the field of building materials, in particular to a glass-ceramic-ceramic composite plate and a production method thereof. Background technique

[0002] At present, the general glass-ceramic for imitation stone is mostly made of CaO-Al 2 o 3 -SiO 2 , MgO-Al 2 o 3 -SiO 2 or CaO-MgO-Al 2 o 3 -SiO 2 Several limited base glasses are used as mother glasses, and appropriate amounts of other modified components are added to obtain excellent comprehensive process performance, and a large number of patented glass compositions are derived.

[0003] Japanese Patent Publication 50-116515 (Application No. 49-023175, published on September 11, 1975) disclosed the following content: 2 o 3 -SiO 2 On the basis of the ingredients, an additional (Na 2 O+K 2 O), in addition to specifying (BaO+ZnO) as an essential component, in order to further improve the fluidity in the sintering-crystallization process.
