Embodiment Construction

[0020] Hereinafter, the present invention will be further described in detail with reference to the examples, but the embodiments of the present invention are not limited thereto.

[0021] The preparation process of the glass-ceramic composite board for kitchen and bathroom countertops includes the following steps:

[0022] S1: Weigh the raw materials and mix them evenly. The components of the raw materials and their respective mass percentages are: 55-63% SiO 2 , 5-7% of A1 2 O 3 , 15-16% CaO, 3-6% ZnO, 2-5% Na 2 0, 4-5% CaF 2 , 1-3% of B 2 O 3 ; In practical applications, the aforementioned raw materials can also include 0.2-0.8% Sb 2 O 3 ;

[0023] S2: Put the uniformly mixed raw materials in step S1 into a high-aluminum crucible, put it into a silicon-molybdenum furnace and raise it to 1480°C at a heating rate of 3°C / min, raise it to 1480°C and keep it for 2 hours to obtain molten glass;

[0024] S3: After the heat preservation is over, pour the molten glass on the preheated flat i...

Abstract

The invention discloses a preparation technology of a microcrystallized glass-ceramic composite plate as a bench surface in a kitchen or a bathroom. The preparation technology comprises weighing 55-63% of SiO2, 5-7% of Al2O3, 15-16% of CaO, 3-6% of ZnO, 2-5% of Na2O, 4-5% of CaF2 and 1-3% of B2O3, mixing the materials to obtain a uniform mixture, putting the mixture into a high-alumina crucible, putting the high-alumina crucible into a silicon-molybdenum furnace, carrying out heating to a temperature of 1480 DEG C, carrying out thermal insulation for 2h to obtain melt glass, pouring the melt glass onto a preheated flat iron plate, pressing the glass liquid through the iron plate to obtain a thin sheet with the thickness of 3-5mm, putting the thin sheet into a furnace at a temperature of 620-630 DEG C, carrying out annealing for 0.5h, carrying out cooling, putting the thin glass sheet on a common vitrified brick, putting the vitrified brick with the thin glass sheet into a high temperature furnace, carrying out coring and crystallization so that the glass sheet is firmly bonded to the base and carrying out cooling. The preparation technology has less steps, a low cost and a high microcrystalline layer crystallization rate. The microcrystallized glass-ceramic composite plate does not produce granular sensation and has high bonding strength, high strength and high hardness.

Description

Technical field [0001] The invention relates to the field of home improvement and home furnishing equipment, in particular to a preparation process of a glass-ceramic composite board used as a kitchen and bathroom countertop. Background technique [0002] As a new type of high-end building decoration material, glass-ceramic decorative panels have been widely favored by architects and users at home and abroad. However, due to its shortcomings such as high production energy consumption and low finished product qualification rate, the price has remained high, which has become its entry The biggest obstacle for ordinary families. [0003] In recent years, glass-ceramic composite panels have emerged as a substitute for pure glass-ceramic decorative panels and have become the new favorite of the building materials market. The combination of glass-ceramic and ceramic tiles realizes the complementary advantages of the two types of materials. It also has the advantages of high gloss, high...
