Problems solved by technology

However, the polymer artificial stone mainly has the disadvantages of large heat deformation, easy deformation and cracking, aging deformation, discoloration, strength reduction due to ultraviolet radiation and temperature, unpleasant gas and non-degradable combustion.
The Chinese patent with the application number 201710760996.X discloses an antibacterial and environmentally friendly mortar prepared from cement, modified oyster shell powder, quartz sand, cellulose ether, calcium carbonate, gypsum, modified diatomite and water, but its antibacterial The compressive strength only reaches 3.1-5.0 MPa, and the mechanical properties are poor. The modified diatomite used in it has strong water adsorption, which affects the fluidity of the mortar, and the modified diatomite has a small density and is not easy to disperse evenly.

Abstract

The invention discloses an antibacterial inorganic high-performance mineral artificial slabstone and a preparation method thereof. The antibacterial inorganic high-performance mineral artificial slabstone comprises the following raw materials in parts by weight: 60-100 parts of cement with the strength not lower than 32.5 MPa, 50-80 parts of an admixture with an average particle size of 5-30 [mu]m, 80-130 parts of fine aggregate with an average particle size of 0.15-4.75 mm; 0.2-0.8 part of a supported antibacterial agent with an average particle size of 20-100 nm; 0.5-2 parts of a water repellent; 3-10 parts of pigment; 3-5 parts of a high-performance additive, wherein the water-binder ratio is 0.16-0.2. The artificial slabstone is good in volume stability, good in antibacterial performance, low in shrinkage, free of buckling deformation in use, extremely low in water absorption rate, good in durability, free of aging and other problems, good in surface stain resistance, low in overall comprehensive cost and suitable for application and popularization.

Description
