preparation example Construction

[0036] The preparation method of described modified calcium carbonate, comprises the following steps:

[0037] S1: Select marble, limestone, etc. transported from the material field to clean and remove impurities, dry the stone to remove surface moisture, and then use a crusher to crush the stone to obtain calcium carbonate fragments;

[0038] S2: transporting the broken calcium carbonate obtained in step S1 into a vertical mill and synchronously adding grinding aids and grinding to obtain calcium carbonate fine stone powder;

[0039] S3: classifying the calcium carbonate fine stone powder prepared in step S2 with a classifier to obtain calcium carbonate powder of 400-600 mesh;

[0040] S4: Add the calcium carbonate powder obtained in step S3 into a high-speed mixer, then add sodium dioctyl succinic acid sulfonate, stannous chloride, and magnesium oxide, raise the temperature to 92-103°C, and heat at 1100-1300r / Stir at a high speed of 24-28min at a speed of 24-28min to prepa...

Abstract

The invention discloses an application of modified calcium carbonate in quartz stone plates. A quartz stone plate comprises the following raw materials in parts by weight: 25-36 parts of modified calcium carbonate, 8-20 parts of a methyl phenyl silicone resin prepolymer, 32-45 parts of an inorganic silicon filler and 10-30 parts of an auxiliary agent. The quartz stone plate is prepared by compression moulding by using the modified calcium carbonate, the methyl phenyl silicone resin prepolymer, the inorganic silicon filler and the auxiliary agent in a corresponding proportion. The modified calcium carbonate is added into the quartz stone plate, has small probability of agglomeration phenomenon, and has good dispersibility, and the various mechanical properties of the modified calcium carbonate are increased notably.

Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of quartz stone plates, and in particular relates to the application of modified calcium carbonate in quartz stone plates. 【Background technique】 [0002] As the latest artificial building material, artificial quartz stone has incomparable advantages of natural stone such as high strength, high hardness, high temperature resistance, corrosion resistance, anti-aging, easy cleaning, wear resistance, pure material, and no radiation. Today, as natural stone is being exhausted as a non-renewable resource, artificial quartz stone is the best substitute. At the same time, artificial quartz stone can use waste glass as raw material, thus realizing resource reuse while protecting the environment. These advantages make Artificial quartz stone has become an upstart in the architectural decoration industry, and is widely used in cabinets, bathrooms, floors and wall decorations in offices and large shopp...
