A kind of concrete protective floor material and preparation method thereof

Abstract

The invention discloses a novel concrete protective floor material. The novel concrete protective floor material is prepared from the following raw materials in parts by weight: 100 to 200 parts of organosilicon modified silicate, 20 to 30 parts of graft modified silicon dioxide, 20 to 30 parts of an acrylic emulsion, 25.5 to 32.5 parts of nanometer lithium silicate, 7 to 13 parts of nanometer calcium carbonate, 5 to 10 parts of a perfluoroalkyl acrylate copolymer emulsion, 3 to 5 parts of 4-hydroxybenzenesulfonic acid, 3 to 6 parts of triethanolamine, 0.5 to 1.5 parts of a wetting agent, 3 to5 parts of a cellulose type water-retaining agent, 0.2 to 0.6 part of an antifoaming agent and 500 to 700 parts of water. The floor material provided by the invention has the functions of improving surface strength and hardness of concrete, increasing wear resistance of the concrete, effectively compacting the surface of the concrete and inhibiting the invasion of corrosive substances like waterand oil, fundamentally retards or prevents the corrosion of the concrete, improves the use performance of the concrete, and prolongs the service life of the concrete.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a concrete protective floor material and a preparation method thereof. Background technique [0002] Concrete has become the building structure material with the largest amount of application and the widest range of use. According to statistics, my country's concrete output in 2012 was as high as 1.2-1.3 billion m 3 , accounting for about 40% of the world's total output. However, its ubiquitous defects such as easy weathering and cracking, sanding, and non-wear resistance have always been a problem that has plagued people and has attracted widespread attention. Although there are many reasons for this phenomenon, it actually affects and reduces the use effect and life of the concrete floor. [0003] At present, the protection methods of concrete floors mainly include surface coating and silane impregnation. The surface coating includes two types of water-based coatings and sol...

Problems solved by technology

However, the construction process of surface coating is relatively cumbersome. It often has a four-layer structure of sealer paint, putty layer, intermediate paint and top paint, and its environmental protection is poor; It is difficult for the harmful impurities it carries to penetrate into concrete, and its construction is simple and relatively environmentally friendly, but its price is high and its weather resistance is poor, so there are few engineering applications
