Abstract
A fire-retardant, anti-static composition for coating articles such as brattice cloth contains fire- retardants, electrolytes, a hygroscopic surfactant, a binder, aqueous and non- aqueous solvents, and an emulsion stabilizer. The fire-retardant compound is chosen from chlorinated paraffins and inorganic compounds selected from the oxides, halides, borates, phosphates and polyalkylphosphates of elements of groups 2-5 of the Periodic Table. The surfactant used has humectant and hygroscopic properties, e.g. an ethoxylate surfactant showing medium hydrophilic/hydrophobic properties. The binder used is elastomeric and polymeric e.g. natural rubber or butyl rubber.
Description
SPECIFICATION
Fire-retardant, anti-static compositions
This invention relates to improved fire-resistant and anti-static coating compositions for articles formed from natural and/or synthetic materials.
More particularly, the invention relates to such coating compositions for coating woven or nonwoven articles such as sheeting, for example hessian, plastic film and woven plastic sheeting.
Without restricting it in any way, the invention relates more particularly to the coating of an article in the form of a laminated sheeting formed from plastic tape such as polyolefin tape woven as warp and weft, having a polyolefin film applied to one side by extrusion coating.
Typical articles for which the invention has immediate application are, for example, air duct piping and brattice cloth. Brattice cloth is used in mines, and particularly coal mines, and is hung in such a fashion as to direct and circulate air throughout the mine.
In such applications, the brattice clotch should have characteristics such as good fire-retardance and good elelectrical conductivity on its surface (i.e., it should be anti-static). The cloth is therefore coated with a fire-resistant, anti-static composition to achieve these ends. The coated brattice cloth should also be resistant to the leaching of water-soluble components from the coating, which helps to prevent the atmosphere in the mine from corroding metal fittings and equipment.
When hung in a coal mine, coal dust accumulates on brattice cloth, requiring periodical hosing down to remove the dust. Partly for this reason, prior art fire-resistant, anti-static coatings for such cloth suffer in that there is gradual deterioration of the coated cloth by the soluble chemicals being washed out of the coating.
A further disadvantage of prior art formulations is their lack of emulsion stability, which gives rise to difficulty with the storage of the coating composition prior to coating the cloth.
A further problem with prior art coating compositions is that, following their application on brattice cloth, for example, the coating, after drying, tends to have an excessive affinity for water. Although some degree of hygroscopicity is a necessary property to enhance electrical conductivity, too much "sweating" of the surface inconveniences handling and accelerates soiling of the fabric by coal dust in the mine atmosphere.
An example of a prior art composition is described in AU-A-474,627 of Rheem Australia Ltd.
In this specification, the term "article" is to be understood as referring in particular to cloth and similar articles, but the coating composition of the invention can be applied to any other article, where fire-resistant and anti-static properties will be of use.
Accordingly, this invention is intended to substantially overcome or ameliorate the aforementioned problems by the provision of a new, improved fire-resistant and anti-static coating composition.
According to the invention, there is provided a fire-retardant, anti-static composition for coating articles formed from natural and/or synthetic material, said composition comprising,
(a) at least one fire-retardant compound chosen from highly chlorinated paraffins and inorganic compounds chosen from the oxides, halides, borates, phosphates and polyalkylphosphates of elements of groups 2 to 5 of the
Periodic Table,
(b) at least one water-soluble electrolyte,
(c) at least one surfactant having humectant and hygroscopic properties,
(d) at least one elastomeric and polymeric binder,
(e) an aqueous solvent, and
(f) a non-aqueous solvent, and
(g) at least one emulsion stabilizer.
The invention also concerns a method of preparation of the above composition, and a method of coating articles with the composition.
There are a diversity of materials which may be used as fire-retardant compounds; their selection will be based on effectiveness, cost and other similar requirements.
The level of surface electrical conductivity required for some applications, such as brattice cloth, is so high that it often cannot be achieved in a reliable manner by utilising a conventional antistatic agent. The achievement of the necessary level of electrical conductivity then requires the use of an electrolyte phase comprising an electrolyte and a hygroscopic agency within the surface of the coating.
Consequently, a desirable composition comprises a mixture of organic and inorganic chemicals that are finely dispersed, intimately mixed and bonded together and to the articles in a manner to resist the exigencies of use.
There are many fire-retardant compounds which can be used in the present invention. A preferred compound is the group of highly chlorinated paraffins. These paraffins are longchain, saturated, chlorinated, linear hydrocarbons preferably containing 20 to 30 carbon atoms, about 70% chlorine by weight and having a softening point of from 70 to 1 00 C. Other fireretardant compounds are inorganic compounds such as antimony oxide. The use of such compounds as antimony oxide together with the highly chlorinated paraffins results in a fireretardant synergism. Inorganic compounds similar to antimony oxide which can function as fireretardants and synergists are the oxides, halides, borates, phosphates and polyalkylphosphates of elements of groups 2 to 5 of the Periodic Table.
The composition of the invention also includes a water-soluble electrolyte which functions as an anti-static agent. Some suitable electrolytes are sodium tetraborate decahydrate and calcium chloride. As mentioned above, it is important to also include a surfactant having humectant and
hygroscopic properties to improve the conductivity, and hence the anti-static properties, of the composition. For example, a suitable surfactant is an ethoxylate, showing a medium hydrophilic/hydrophobic balance.
A binder is necessary for making the composition adhere to the articles. An elastomeric, polymeric binder has the best balance of properties in terms of adhesion, waterresistance and flexibility. Suitable binders are natural rubbers, synthetic rubbers, or mixtures of the two. A preferred binder is unsaturated butyl rubber.
The composition also contains an aqueous solvent and a non-aqueous solvent. The aqueous solvent is most preferably water, and the nonaqueous solvent is preferably a hydrocarbon solvent, for example, having a boiling range between 90" and 1300C.
As a preferred embodiment, the composition may also contain a solvent coupler, to assist in the mixing of the two solvent systems. A preferred coupler is a monohydric alcohol such as propanol.
The composition also contains an emulsion stabilizer. A suitable stabilizer is a glycol ether.
Preferably a glycol monoether is used. Two examples of suitable glycol ethers are diethylene glycol monobutyl ether and ethylene glycol monobutyl ether. Alternatively, other generally known stabilizers can be used.
The composition is prepared by mixing the aqueous solvent (i.e. water) with the hydrophilic components of the composition. The hydrophobic components are similarly mixed with the nonaqueous solvent. The two solvent systems are then mixed together to form a stable emulsion.
The viscosity of the emulsion is preferably sufficient to allow knife coating of the brattice cloth or other article.
The composition is coated on to the article or cloth, and allowed to dry. The coated article retains some level of moisture as described earlier, according to the amount of moisture in the atmosphere and general environment.
A particularly preferred composition is one which comprises
(a) (i) 1 5 to 50 parts by weight of long-chain, saturated, chlorinated, linear hydrocarbons of from 20 to 30 carbon atoms, containing about 70% chlorine by weight, and having a softening point of from 700C to 1 000C, (ii) 2 to 10 parts by weight of antimony oxide,
(b) (i) 0.1 to 5 parts by weight of sodium tetraborate decahydrate,
(ii) 1 to 30 parts by weight of calcium chloride.
(c) 1 to 10 parts by weight of an ethoxylate surfactant showing a medium hydrophilic/ hydrophobic balance,
(d) 20 to 30 parts by weight of unsaturated butyl rubber,
(e) 4 to 5 parts by weight of water,
(f) 20 to 30 parts by weight of a hydrocarbon solvent having a boiling range of from 900C to 1300C, (g) 20 to 30 parts by weight of a glycol ether, and
(h) 5 to 30 parts by weight of propanol as a solvent coupler.
It will be understood that, for a particular method of application and end use of the article, the percentage of the components should be adjusted to best advantage to give a satisfactory working formulation.
The amount of composition required may be varied depending upon the variation in the required properties of the article to be coated, but it is likely to be of the order of 1% to 20% of the weight of the coated article. In this range, coatings usually display a maximum electrical resistance of 3x 108 ohms when tested to the
National Coal Board (UK) Specification Number 1 58/1980.
