Description
Technical field
The present invention relates to functional coating coating technology, especially a kind of osmosis type self-leveling cement anti-static and abrasion-resistant floor coatings
Application method.
Background technology
Self-leveling cement is a kind of New Building Materials, is widely used in factory, city public works, has and applies
The advantages that work is simple for process, good combination property is increasingly becoming the first choice of each terrace construction material.
However, self-leveling cement floor material, as other inorganic material, resistivity itself is higher, belongs to insulation material
Material, cannot meet and be wanted in the anlistatig of workplaces such as the workshops and gas station of Electronics Factory or various precision instrument factories
It asks.In general, can be by the way that conductive filler (such as mica, metal powder, fiber) be added very in cement to the antistatic treatment of terrace
It is realized to copper mesh is added in terrace, but this method and process is more complex, while the performance of cement can be influenced, for having applied
The good self-leveling cement terrace of work can not carry out antistatic treatment.
Another kind is to coat one layer of antistatic coating in terrace surface for the antistatic treatment mode of terrace, is such as invented special
The conductive fillers such as silver, mica are added in sharp CN201410441497.0 in polyurethane floor coatings, coating is in terrace surface shape
At antistatic coating.This terrace belongs to organic coating terrace, is one layer of simple terrace coating of formation above cement layer.Cause
And its electrical conduction mechanism is consistent with the formation mechenism of general antistatic coating, i.e. conductive material distribution forms conductive network in the coating
Reach anlistatig effect, as long as conductive material is enough in such coatings, it is easy to form conductive network to reach anti-
The performance of electrostatic.
And according to the present invention is a kind of inorganic floor material of osmosis type, i.e., floor coatings are by penetrating into cement hole knot
The pore structure of cement is filled up in structure, and reacts to form the mutual inlay of a cement and coating with cement pore structure, to reach
To the effect for improving terrace hardness and impact strength.In terrace prepared by this floor coatings, due to the resistance of cement matrix
Every, terrace coating in discontinuously arranged state thus conductive material also be difficult to be formed complete conductive network, and conductive network
Formation is the key that antistatic property, and on the other hand, the pore structure of self-leveling cement terrace is smaller, and permeance property is poor, thus
The scale size of conductive material can not be too big, and micron-sized conductive material can not use.
For this problem, the present invention from the performance of conductive material and structure, select electric conductivity it is excellent mix tin
Indium oxide (ITO) nanometer granular nano powder is main conductive material, the higher linear nanometer material of simultaneous selection electric conductivity
Expect that Al-Doped ZnO (AZO) is collocation conductive material, conduction is improved by the way that the addition of linear ZAO of conductive network is more readily formed
The formation probability of network improves the electric conductivity of material using ITO simultaneously, to realize the anti-quiet of osmosis type abrasion-proof terrace coating
Electrical property.
