Description
IMPROVEMENTS IN OR RELATING TO FLOOR AND WALL COVERINGS
This invention relates to floor and wall coverings, and more particularly to floor coverings for use in areas of high noise level or where noise reduction or sound absorbent materials are required.
The problem of noise levels at work is under constant review, and in many industries workers are routinely provided with ear defenders. A recent area of concern is in the bays for loading and unloading of heavy lorries and trucks, for example at warehouses, depots and shops.
Loading and unloading often takes place in relatively confined spaces, and the moving of equipment such as wheeled pallets and trolleys over the metal flooring of the scissor lifts and dock levellers frequently used for loading and unloading can give rise to sound reverberation levels of 105 dB and above, which is a level at which actual damage to human hearing can take place. In addition, supermarkets are often located in residential areas, and as loading and unloading must of necessity frequently take place at night, the noise nuisance to the local community is considerable.
Hitherto the problem has simply been addressed by providing the workers concerned with ear defenders. This of course does nothing to abate the nuisance to the local community. It has now surprisingly been found, however, that very significant improvements in noise reduction can be obtained by the use of certain new materials as floor coverings for the trucks, scissor lifts, dock levellers, and other equipment used.
The mechanical requirements for floor coverings in these situations are very severe. Firstly they must be tough and abrasion resistant to withstand the mechanical forces of the roll pallets, wheeled trolleys and other equipment. Secondly they need to be chemically resistant, to withstand spillages of a wide variety of potentially corrosive household materials, such as acids, alkalis, detergents, oils and solvents. Thirdly they must have good anti-slip properties in both wet and dry conditions. Fourthly they must have excellent chemical and mechanical adhesion to the underlying substrate.
Fifthly they must have sufficient flexibility to accommodate flexing of the underlying substrate, which can be considerable in the case of metal floors. Finally the floor covering must be easy to apply, and preferably seamless, which almost inevitably means that it must be a hardenable liquid resin system. The viscosity of the resin is particularly important in the application to metal floors, since it must be self-levelling and able to penetrate the grooves of the floor pattern, whilst forming a flat coating layer of the required thickness over the entire surface. A further limitation placed on any resin system by the food industry is that the components of the system should have a low odour, and should not taint any food products in the vicinity.
This, for example, means that isocyanates cannot normally be used in such applications.
Hitherto the only floor coverings that have been proposed for metal floors have been acrylic paints and epoxy resin coatings containing a non-slip aggregate.
Whilst they have good abrasion resistance, chemical resistance and adhesion, they are excessiveli brittle and inflexible, are thus susceptible to cracking, and by themselves also have inadequate anti-slip properties. In addition, of course, they provide little, if any, reduction in noise levels.
The present invention provides, in one aspect, a covering material for a metal flooring which provides a reduction in noise rating (as hereinafter defined) of at least 10%.
In another aspect the invention provides a covering material for a metal flooring which comprises an epoxy/urethane resin blend.
In still another aspect, the invention provides a floor or wall covering material composition which comprises a self-levelling blend of
(i) 10 to 50% by weight of a liquid synthetic
resin containing epoxy groups, and
from 5 to 70% by weight of a liquid
prepolymer containing urethane and ester
groups and from 10 to 30% by weight of a
liquid curing agent or which comprises
(ii) from 40 to 60% by weight of a branched
polyalcohol containing ether and ester
groups,
from 20 to 30% by weight of an isocyanate,
and
from 0.1 to 10% by weight of a catalyst.
In this specification noise rating is defined as the average sound pressure level in dB measured at the centre octave frequencies within the range 31.5Hz to 20 KHz when a roll pallet loaded with a 300 Kg weight is manoeuvred across a lowered scissor lift floor plate, with maximum ambient background noise of 85 dB.
Preferably the covering material has a Shore hardness, as measured by a Durometer, of from 70 to 95A, most preferably from 75 to 85A.
Preferably the covering material has a flexural strength of from 10 to 60 MPa, most preferably from 20 to 40 MPa.
Preferably the covering material comprises one or more particulate fillers to improve further its abrasion resistance and non-slip properties. Suitable fillers include, for example, finely ground minerals, oxides and aggregates such as silica, mica, sand and quartz. The filler preferably has an average particle size of from 0.1 to I.Omm, and for example a typical grading for the particulate filler is:
Sieve Size Approx. % of mix
1.0 - 2.0mm 8
0.7 - 1.2mm 22
0.3 - 0.7mm 20
0.1 - 0.33mm 45
50-100 microns 5
The filler or fillers can be mixed into the material composition before application, or spread as a topping over the material composition whilst it is still tacky, or both.When some or all of the filler is used as a topping, it is preferred to seal the topping in place using an anti-slip seal coat of a moisture-curing resin, such as for example a polyurethane.
It may also be possible to improve still further the sound absorbent properties of the covering material by the use of sound absorbing filler particles such as hollow microspheres, finely divided cork or finely divided rubber particles. Where such fillers have less acceptable abrasion resistance properties they could, for example, be included in a first undercoat of the material composition, and a second coat comprising a more abrasion resistant filler or fillers applied thereover.
The covering material preferably comprises from 30 to 70% by weight, most preferably from 40 to 60% by weight, of the particulate filler.
The thickness of the covering material is preferably at least lmm, more preferably from 2mm to 5mm. When the covering is applied to a metal flooring, having for example a checkerboard pattern impressed therein, the depth of the covering is preferably such that it fills the grooves in the metal flooring and extends to a thickness of about 2mm above the metal flooring surface.
The viscosity of the covering material composition, after the components have been mixed together, is such that when used as a floor covering the composition is self-levelling, and is capable of entering any grooves in the metal flooring. When used as a wall covering the composition should have a viscosity sufficient to form a film of the required thickness on the walls. A preferred viscosity range for the covering material composition is from 100 to 500cp. The covering material composition can be applied by any suitable method, for example by a plasterer's float, a notched trowel, or by brush or roller.
Suitable liquid resins containing epoxy groups include, for example, epoxy resin prepolymers having an average molecular weight of less than 1000, preferably less than 700.
The liquid prepolymer containing polyurethane and ester groups can be for example a prepolymer resin containing urethane and acrylate groups in a ratio of for example 2 to 1, or a prepolymer resin containing ether, urethane and blocked isocyanate groups in a ratio of for example 2 to 1. The isocyanate groups may be blocked with phenol or by any other suitable means. The prepolymer preferably has an average molecular weight of from 4500 to 5000.
The curing agent can be chosen from a wide range of materials. For example, suitable polyamides, polyaminoamides, cycloaliphatic amines, tertiary amines,
Lewis acid bases, Mannich bases and aliphatic amines can all be used. Examples of preferred amine curing agents include isophorone diamine, trimethyl-hexamethylene diamine N-(2-aminoethyl) piperazine, 2aminocyclohexylmethane and 3,3' dimethyl 4,4' diamine dicyclohexy methane. The amine curing agents are preferably used in admixture with benzoylalcohol and salycylic acid.
The branched polyalcohol containing ether and ester groups is preferable one having a hydroxyl content in the range 2 to 12%. It can, for example comprise ether and ester groups in a ratio of from 2.2 to 1.0. Suitable ester groups may include, for example acrylate, methacrylate, acetate, propionate and similar groups.
The diisocyanate can be an aliphatic, cycloaliphatic or aromatic diisocyanate, a preferred material being diphenylmethane 4,4' diisocyanate. Suitable catalysts include, for example, diazobicyclooctane, dibutyltindilaurate and tin (II)-octoate.
As previously mentioned, isocyanate-containing compositions are not recommended for use in food handling areas.
The covering material composition also preferably comprises a diluent, and by varying the diluent level the viscosity of the composition can be optimised. Suitable diluents include for example diols such as 1,4 butane diol, aminoesters, and plasticisers such as dibutyl pthalate.
The Shore hardness of the epoxy/urethane resin blend can be varied as desired by adjusting the ratio of the epoxy resin precursor to the polyurethane resin precursor. The rate of cure is dependent on the curing agent used and can be increased by the addition of appropriate accelerators.
wetting agents, for example fluorocarbons, defoaming agents, for example silicone oil, and desiccating agents can be added to the composition as required.
The covering materials of the invention can be used in a variety of applications where noise and sound reduction is important. Thus, in addition to the covering of metal flooring as previously discussed, the covering materials may find application in covering metal stairs and gangways, escalators and factory floors.
Although the invention has primarily been described in terms of floor covering materials, the invention may also find application in wall coverings, for example for sound-proof rooms, recording studios, and auditoriums.
The invention is illustrated by the following
Examples:
EXAMPLE 1
A composition is made up by mixing the components listed below at room temperature:
Liquid epoxy resin (average molecular weight less than 700) 28.00 Kg
Liquid prepolymer containing urethane and acrylate groups 19.33 Kg 1,4 butane diol 3.00 Kg
Silica filler (average particle size 300 microns) 36.00 Kg
Fluorocarbon wetting agent 60 grams
Silicone oil defoaming agent 130 grams
Curing agent (containing 70% isophorone diamine, 25% benzoyl alcohol and 5% salycylic acid) 12.24 Kg
The composition is applied to the steel floor of a scissor lift in the following operation:
The steel floor surface of the scissor lift is first grit blasted to SA 2 to remove surface contaminants and produce a bright etched surface. The steel surface is then treated with a suitable primer and allowed to tack off for 2-3 hours.The composition is then spread onto the prepared surface using a notched trowel to a thickness of 5mm. A spike roller is applied to the wet resin as necessary to release any entrapped air bubbles.
The composition is then allowed to cure overnight. Next a polyurethane seal coat is applied to the composition and a fine silica quartz aggregate evenly broadcast onto the wet surface. The seal coat is allowed to cure for 34 hours, excess aggregate brushed off, and a final polyurethane seal coat applied with a roller. The covering material is able to accept vehicle traffic after 12 hours.
It is found that using a covering material according to the invention the noise rating can be reduced by as much as 20%.
EXAMPLE 2
The procedure of Example 1 is repeated except that the 1,4 butane diol is replaced with 2Kg of dibutyl pthalate.
EXAMPLE 3
The procedure of Example 1 is repeated except that there is used as the filler a quartz flour having an average particle size of 300 microns in an amount of 36Kg.
EXAMPLE 4
The procedure of Example 1 is repeated except that there is used a composition as follows:
Epoxy resin (average molecular weight less than 700) 28.00 Kg
Prepolymer containing ether, urethane and blocked isocyanate groups 28.00 Kg 1,4 butanediol 4.00 Kg
Silica filler (average particle size 300 microns) 36.00 Kg
Fluorocarbon wetting agent 70 grams
Silicone oil defoaming agent 140 grams
Curing agent (containing 60% isophorone diamine, 30% benzoyl alcohol and 5% salycylic acid) 11.90 Kg
EXAMPLE 5
The procedure of Example 1 is repeated except that there is used a composition as follows:
Branched polyalcohol with ether and ester groups 100
Aminoester diluent 5
Dibutyl tin dilaurate 0.1
Silica filler (300 mesh) 100
Desiccating agent 10
Diphenylmethane 4,4' diisocyanate 30-50
