Chinese Patent Application No. 200710009963.8 "Light-transmitting Artificial Marble and Its Manufacturing Method" (publication number CN101186464A) discloses a light-transmitting artificial marble, using transparent unsaturated polyester resin as the adhesive, and the filler mainly uses Ultrafine calcium carbonate powder is produced by conventional equipment, which is still basically the production method of artificial marble. Although the translucent marble produced has optical characteristics of light transmission, it is artificial stone after all and lacks natural texture. Whether it is In terms of texture, strength, weather resistance, etc., they are greatly inferior
From the perspective of natural marble, if there is any composite material of light-transmitting natural marble and other materials, since the existing composite materials are basically bonded with adhesives, there is no special requirement for the usual bonding method. Composite materials, there will be many problems such as poor bonding, uneven appearance, gaps in the interface layer, and bubbles.

Embodiment Construction

[0015] Prepare a natural marble slab 1 with a pattern and light transmission with a thickness of 1.5mm to 10mm, preferably 1.8mm, and an inorganic glass plate 3 or organic glass plate 3' of the same size and shape. The thickness of the glass plate is 8mm to 10mm. 25mm, preferably 15mm; after cleaning, apply a thin layer of epoxy adhesive 2 on each side, preferably the epoxy adhesive specially used for dry-hanging stone curtain walls, such as JC887-2001 type. Since epoxy adhesives are divided into components A and B, they must be used in time and processed in time. When bonded into a composite panel (see figure 1 As shown), send it to the vacuum environment immediately, gradually evacuate to an absolute vacuum of 80Kpa ~ 95Kpa (kiloPascal), then keep it, and maintain it at a temperature of 10°C ~ 30°C for 10 hours to 30 hours, until the composite board After being completely bonded firmly, the vacuum is released, and the workpiece is taken out to obtain the light-transmitting ...

Abstract

The invention discloses a light-previous natural marble composite board and a producing method thereof, wherein, a light-previous natural marble board 1 is laminated with an inorganic glass board 3 or an organic glass board 3'; an epoxy adhesive 2 is coated on the laminating interfaces respectively; and the thickness of the marble board 1 is about 1.5mm to 10mm; the thickness of the inorganic glass board 3 or the organic glass board 3' ranges from 8mm to 25mm. The laminated composite board is maintained for 10h to 30h at absolute vacuum of 80MPa to 95MPa and the temperature of 10 DEG C to 30 DEG C to obtain the products of the invention. The composite board has easy and simple manufacturing method, good optical performance, excellent weather resistance and hard aging. The method solves the problem that bubbles generally appear in a bonding layer, and has good product mechanical performance. The light-previous natural marble composite board is applicable to screen wall materials and advertisement and building decoration.

Description

technical field [0001] The invention relates to a curtain wall stone material, in particular to a light-transmitting marble composite board and a manufacturing method thereof. technical background [0002] Because marble is both durable and decorative, its application fields are becoming more and more extensive, and it is developing in depth, and some new application fields have emerged. Outside buildings or on advertising walls, curtain wall stone is a new building and decoration material. Chinese Patent Application No. 200710009963.8 "Light-transmitting Artificial Marble and Its Manufacturing Method" (publication number CN101186464A) discloses a light-transmitting artificial marble, using transparent unsaturated polyester resin as the adhesive, and the filler mainly uses Ultra-fine calcium carbonate powder is produced by conventional equipment, which is still basically the production method of artificial marble. Although the translucent marble produced has optical charact...
