Abstract
The invention relates to a manufacturing method for floor board with perfect conductivity and BVG performance. It uses combination as floor board substrate. The combination contains concrete and the mixture of polymer film forming combination. And the combination preferred is aqueous; the polymer preferred is polyurethane.
Description
Technical field
The present invention relates to the floor, and relate more particularly to make method as floor with ideal conducting performance.
Background technology
Has the zone of the material of obvious fire or explosion hazard in processing, or in the zone of electronic component assembling, desirable floor, the generation of particularly industrial floor reply electrostatic charge and/or store and does not have conductibility.Such electric charge is typically moved around on the floor and is produced by people, material and facility easily, is called " frictional electricity " phenomenon.Ratione personae is because of the special sole type of using of their anti-skidding or chemical resistance usually is exactly those types that produce high-level static.In this case, need have apace static with any generation and conduct the floor fallen.Special hope reduces " body voltages produces (body voltagegeneration) " (being called " BVG " hereinafter).This is the voltage that is moved around and produced on the floor by the people.A kind of measuring method is the AATCC/ANSI134 test method, and it relates to the footgear that uses with expectation is the test theme, and the walking of being scheduled on desired floor surface circulation is also measured the maximum body voltages that is produced.Not only this should reduce as far as possible, and ideally, any such voltage should be eliminated fast by the floor.
Floor with perfect conductivity is a kind ofly to have 25,000-1 * 10
9The point-to-point resistance of ohm, it is measured according to for example ASTM F150 or DIN EN 1081, and this floor has the BVG of maximum 100V, and it is measured according to ESD STM 97.2.Think to have 25,000-1 * 10
6The floor of the point-to-point resistance of ohm is an electrically-conducting floor, and it typically is used for existing fire or the living field of explosion danger.Interim European standard prEN 1504-4 lists: floor such as I level (10
4-10
6Ohm) be used for explosive and II level (10
4-10
8Ohm) be used for explosive and dangerous substance.Think and have 1 * 10
6-1 * 10
9The floor of the point-to-point resistance of ohm is the static floor that disappears, and such floor is mainly used in the electronics industry.
The flooring compositions in past utilizes conductive material to obtain these perfect performance.Such typical flooring compositions comprises the polymer substrate that is filled with iron or steel filler.Other possible material is magnetic iron ore (magnetic oxide) and ferroalloy materials.This is relatively costly solution.Other method comprises conductive surface layer is applied to for example concrete floor.This is more cheap and convenient method, but it has the shortcoming that lacks durability, comprises frequent smearing again.
Summary of the invention
Have now found that and might make a kind of durable floor, its in fact or even fully overcome the defective on the known floor of prior art, and durable and electric conductivity all reaches acceptable degree.Therefore, the invention provides the method that a kind of manufacturing has the floor of above-mentioned desired electrical performance, it comprises composition is applied to floor substrate, and wherein said composition contains the mixture of the polymer film forming composition of cement and suitable floor using.
The present invention also comprises in addition and has 25,000-1 * 10
9The floor of point-to-point resistance of ohm and the BVG of maximum 100V, polymeric matrix is contained on this floor, and cement granules is scattered here and there in the wherein said matrix.
The major advantage of this method is that the floor does not need to use conductive material.These materials not only expensive and also they also can introduce they self problem.For example, iron and steel filler can get rusty, and it makes any floor of containing them become ugly, and helps to cause its deterioration.Floor by the inventive method preparation is very durable and impact-resistant.It also is good especially with regard to lower BVG.
Being used for polymer composition of the present invention can be any thermoplasticity or the thermoset polymer compositions that is used to form coating composition.They can be moisture or water-free (preferred moisture) and they can be solution, dispersion or emulsion.Polymer composition must be applicable to flooring compositions.Or rather, it must form adhesive film, and wherein said film has the intensity that is enough to withstand the suffered the sort of traffic volume in floor.Not every film-forming composition can both accomplish that like this some compositions for example is suitable for wall paint, but can not withstand the floor traffic volume very chronically fully.It is what that the technician can easily understand needed here, and the selection of suitable material also is known in the prior art.
Any suitable this polymer type of using well known in the prior art can be used among the present invention.Example comprises epoxy resin, polyester, polyacrylic acid, polyethylene and polyurethane.
Preferably polymer is a thermosetting polymer, that is to say, can make it form crosslinked film.These material production tough and tensile, the most durable film.Polymer composition is preferably water base.Use and dry period between, this has reduced expense and undesirable smog is minimized.
