Description
Technical Field
The invention relates to a terrace material, in particular to an anti-static super-wear-resistant terrace material, and belongs to the technical field of terraces.
Background
The terrace is the ground which is constructed and treated by using specific materials and processes and shows certain decoration and functionality on the original ground, is the part of a bottom room which is contacted with a soil layer, bears the load of the bottom room, is required to have certain strength and rigidity, and has the performances of moisture resistance, water resistance, heat preservation and wear resistance. The stratum has close relation with the outdoor site of the building, and the relation between the terrace and the platform, the step and the site along the edge of the building needs to be processed, so that the building is clearly connected with the site and is harmonious as a whole; the mortar terrace is a short name of epoxy resin mortar terrace, and the epoxy resin mortar is a mortar grouting material with high solidification speed and high viscosity;
the electrostatic phenomenon widely exists in the nature, along with the application of a large amount of high polymer materials, the electrostatic electrification is more and more emphasized by people, and the static electricity is utilized by the human beings and brings disasters to the life and the production of the human beings. The ground level is easy to accumulate a large amount of static charges due to frequent friction, so that the production process is hindered, the product quality is influenced, and even fire, explosion and other safety accidents can be caused seriously. The following two methods are mainly used for preventing the polymer material from static electricity: 1) The material structure is changed to have the conductive capability; 2) And adding a conductive additive or a conductive filler. For polyurethane materials, the former method is rarely reported at home and abroad, and the industrial application is far from the realization of the former method, and the latter method is simple and convenient and has more applications in industry. However, either the conductive aid or the conductive filler has respective drawbacks: the conductive additive has poor timeliness, becomes invalid after a period of time, and cannot keep good conductive performance for a long time; the conductive filler has poor conductive capability, and can obtain good conductive performance only by adding a large amount of the conductive filler, but can cause the cost of the coating to rise and the comprehensive performance to decline, and the conductive filler has dark color and large oil absorption, and the color and the leveling effect of the coating can be influenced by adding a large amount of the conductive filler.
At present, the antistatic terrace on the market has the wearing resistance relatively poor, the antiskid nature is poor, the weatherability is relatively poor, construction thickness is big etc. not enough, can not satisfy the requirement of the industry factory building terrace that has load requirement, high traffic flow, for example: CN 109627914A discloses an epoxy antistatic floor coating, which realizes an antistatic function by adding conductive mica powder and conductive fibers, but the floor has poor wear resistance and weather resistance; CN 106946514A discloses an antistatic polyurethane mortar terrace, which not only has an antistatic function, but also has
Excellent physical and mechanical properties and chemical resistance, but the construction thickness is more than 3mm, and the construction cost is high; 30CN 107964341A discloses a novel polyurethane antistatic coating prepared by adding single-walled carbon nanotube
The obtained terrace has excellent weather resistance due to the existing anti-static function, but the outer plasticizer is easy to migrate in the using process of the terrace due to the addition of the outer plasticizer, so that various mechanical properties of the terrace can be influenced, the service life of the terrace is reduced, and therefore, the anti-static super-wear-resistant terrace material is provided.
