A self-cleaning outdoor artificial stone slab and its preparation method

Abstract

The invention relates to the field of artificial stone technology, and discloses a self-cleaning outdoor artificial stone slab and a preparation method thereof. The self-cleaning outdoor artificial stone slab is prefabricated from ultra-high performance mineral powder with a compressive strength of 100-150 MPa. The ultra-high-performance mineral powder includes the following raw material components in parts by weight: 80-100 parts of mineral active powder, 8-13 parts of titanium dioxide, 150-220 parts of self-cleaning aggregate, 4-8 parts of nano-silica 0.5-2 parts of water-repellent agent, 10-15 parts of water, 2-4 parts of water-reducing agent, 4-10 parts of pigment, the self-cleaning aggregate is quartz sand, river sand, Manufactured by one or more combined modifications in machine-made sand. The artificial stone slab of the invention has good volume stability, good self-cleaning performance, low shrinkage, no warping and deformation during use, extremely low water absorption, good durability, no aging problems, good surface stain resistance, and low overall comprehensive cost. The cost is low, and it is suitable for promotion and use.

Description

technical field [0001] The invention relates to the technical field of artificial stone, and more particularly relates to a self-cleaning outdoor artificial stone slab and a preparation method thereof. Background technique [0002] With the upgrading of material manufacturing technology and equipment, people's aesthetics and quality requirements, artificial stone panels have high strength, high flame resistance, high weather resistance, high acid and alkali resistance, wide color options, realistic imitation stone effects, and good decorative effects. , Suitable for factory production, convenient construction and other advantages, making it a decorative material for interior and exterior walls of various high-end buildings today. [0003] With the development of industrial economy, industrial waste gas, automobile exhaust, smog and other pollution come one after another. The artificial stone decorative panels used in outdoor buildings are inevitably polluted. These pollutant...
