Abstract

The invention relates to a BDAPP type artificial granite plate and a preparing method thereof. The granite plate is prepared from granite powder and BDAPP type resin in the mass ratio of 100:(5-10). The preparing method comprises the steps that epoxy resin and BDAPP are stirred and mixed, a reaction is carried out for 0.5-1 h at 115-125 DEG C, the temperature is reduced to 60 DEG C or below, a latency curing agent LRC30 and liquid anhydride are added and stirred, and the BDAPP type resin is obtained; the BDAPP type resin and the granite powder are mixed evenly, pressed for preforming, heated, pressurized, cured and formed, and the BDAPP type artificial granite plate is obtained. According to the BDAPP type artificial granite plate and the preparing method thereof, raw materials are convenient to obtain, the preparing process is simple, no solvent is adopted, environment friendliness is achieved, and the product is excellent in comprehensive performance and capable of being widely applied to the building material field such as high-end hotels, airport waiting halls, waiting buildings and stations of high-speed rails, household kitchens and baths and office business buildings, and has good market application prospects.

Description

technical field [0001] The invention belongs to the field of organic-inorganic composite materials and their preparation, and in particular relates to a BDAPP artificial granite plate and a preparation method thereof. Background technique [0002] Granite slab is a high-quality building material, which is widely used in high-end luxury hotels, airport waiting halls, high-speed rail waiting buildings and platforms, home kitchens and bathrooms, office and business buildings, etc. With the improvement of people's living standards, the demand for granite slabs is increasing day by day, thereby further promoting the mining and processing of granite mines, and the scale and quantity are becoming larger and larger. However, in its mining and processing process, a large amount of stone slurry and granite powder waste will inevitably be produced, which will cause serious environmental pollution to rivers, mountains and rivers, and storage yards. greater potential threat.
