Abstract

The invention provides an artificial marble raw material composition. The artificial marble raw material composition comprises 20 to 40wt% of an unsaturated polyester resin, 20 to 50wt% of an inorganic filler, 15 to 40wt% of silica aerogel, 0.2 to 1wt% of a curing agent and 0.2 to 1wt% of a promoter. The invention also provides an artificial marble. The artificial marble is prepared by uniformly mixing the artificial marble raw material composition, putting the mixture into a mold and carrying out curing molding. Through utilization of silica aerogel having a nano-porous structure, the artificial marble has the advantages of light weight, excellent flame resistance, good weatherability and good sound insulation.

Description

technical field [0001] The invention belongs to the field of building decoration materials, in particular to a raw material composition of artificial marble and an artificial marble. Background technique [0002] Artificial marble is a new type of building decoration material developed in recent years. It is made of unsaturated polyester resin and fillers. It has various colors, has the appearance and texture of natural granite, and has the processability of synthetic materials. It is used in building decoration. fields are widely used. [0003] At present, the preparation method of artificial marble on the market is mainly as follows: mixing and stirring unsaturated polyester resin with curing agent, accelerator, filler and various flame retardant additives, and then curing and molding in a mold. Although the artificial marble has a certain flame retardancy, it will still be ignited when exposed to an open flame, and the combustion will produce harmful gases; at the same t...
