Translucent natural marble composite board and method for producing the same

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...

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.
