Abstract

Fire retardant materials are prepared by treatment of foams with a dispersion of polyvinylidene chloride antimony oxide and a binder. A covering layer of such a material may impart fire resistance to underlying materials, and may be used in bedding, furniture and clothing. Typical materials which may be treated include polyurethane foam, polyesterurethane, polyetherurethane foam, polyvinylchloride foam, foam rubber and polyester fibre. These may be applied as backing to a covering material or applied to an interlinear disposed between a filling material and a covering material.

Description

SPECIFICATION Fire retardant materials This invention relates to fire retardant materials such as foamed plastics, fabrics and fibres which may find use, for example, in construction of furniture, clothing or bedding. This invention also relates to a method of production of such materials.
It is important that foamed, fabric or fibrous materials which are used for furniture, clothing or bedding or other domestic purposes are fire retardant and meet the cigarette and match test for example to BS 5852 Pt 1 and DOE/FR 3, 4, 5 for furniture and bedding. It is also important that any fireproofing treatment does not adversely effect other physical properties of the materials such as handle and durability.
According to a first aspect of the present invention a method of treatment to render a material fire retardant comprises treating the material with a mixture comprising a finely divided dihaloalkene polymer resin, antimony oxide, water and a binder. The mixture preferably comprises a dispersion.
This method can be used to treat furniture, clothing and bedding manufacturers' filling materials including polyesterurethane foam, polyetherurethane foam, polyvinyl chloride foam, foam rubber and non-foamed materials such as polyester fibre. The method can also be used for treatment of covering or lining fabrics for furniture, clothing, bedding and the like.
The dispersion may be applied directly to the covering material of a filling material either as a foamed or non-foamed backing. Alternatively the dispersion may be applied to an interliner disposed between a covering material and the filling material. The specific post-treatment conditions may be varied to suit the particular material treated and the nature of the composite construction.
Preferably the dihaloalkene polymer comprises polyvinylidene halide although alternative polymers of dihaloalkenes may be used. Preferably polyvinylidene chloride is used.
The dihaloalkene polymer is preferably in the form of particles having a size of 1103 ym, and preferably in the range of 1 to 200 ym. More prepferably 90% of the particles have a dimension less than 50 mum.
The antimony oxide may be either antimony trioxide, antimony pentoxide or a mixture thereof.
Use of antimony pentoxide is preferred. It has been found that antimony oxide enhances the performance of the dihaloalkene polymer due to formation of oxyhalides.
Binders in accordance with the invention include polymers such as polymer, copolymer or terpolymer latices such as polyacrylics, polychloroprene or polyethylenevinyl acetate. These may be modified so that they are capable of cross-linking with themselves i.e. they are self reactive.
Alternatively non-self reactive latices may be used in conjunction with crosslinking agents, for example natural latex, polyisoprene, styrene-butadiene latex of non-self reactive variations, of the forementioned latices. Latices which have been pre-vulcanised can also be used, for example prevuicanised natural latex. Furthermore mixtures of latices may be used in suitable ratios to combine the properties of the components of the mixture. The binder may incorporate an halogenated polymer latex such as a polyvinylidene chloride film-forming latex e.g. Polidene 33-004 manufactured by Scott Bader.
The dihaloalkene polymer may be dispersed in the binder in a ratio of 1/4 to 20/1 by dry weight.
Preferably the ratio of dihaloalkene polymer to binder is within the range 4/1 to 10/1 by dry weight.
When an halogenated polymer latex is used the ratio of dihaloalkene polymer to binder may be reduced, preferably to the range of 2/1 to 10/1.
The ratio of antimony oxide to binder may be 1/1 to 1/20, preferably 1/10 by dry weight. The ratio of antimony oxide to vinylidene halide polymer in the dispersion may be 1/10 to 1/100 by weight, preferred ratios being 1/25 to 1/50.
The tqtal amount of vinylidene halide polymer and antimony oxide is preferably within the range of 1 50-1000 parts by weight to 100 parts of polyurethane foam. More preferably the total amount of vinylidene halide and antimony oxide lies within the range 200-400 parts by weight per 100 parts of foam.
Addition of a polyvinylidene chloride resin to a rubber latex binder reduces the tack and enhances the handle and durability of the treated product giving improved physical results and compression set, including resistance to flaking out of the powdered additives.
The rubber latex mixtures may be designed and modified to optimise the properties of the treated product to give a desired finish, for example high filler acceptance, low tack or softness.
The dispersion may be applied to a material by any convenient method.
Spray coating and rolling has been found to be a suitable method of application, particularly to polyurethane foams. For example, a 4 mm thick sheet of a suitable low density foam e.g. British Vita VP30, may be spray coated with the mixture and then rolled to force the mixture into the foam to a depth of 3-3.5 mm i.e. not completely through the sheet.
A deposit of 180-300 gm-2 dependent on the type of latex binder used and on the type of product to be protected has been found to be adequate to meet the requirements of BS 5852 Pt 1. The sheet may be used to surround a body of polyurethane foam and the sheet may be covered with a decorative covering. Indirect fire retardancy is imparted to the covering by the underlying impregnated sheet. The impregnated sheet is soft, resilient, flexible and non-tacky, the resultant product having properties only slightly inferior to those of untreated foam.
A foamed dispersion in accordance with this invention may be applied to fabrics or fibres as a back coating. An unfoamed back coating has also been found to be suitable for application to fibres.
Foamed materials such as polyurethane foams may be partially or completely impregnated with the dispersion. The non-foamed material may either be back-treated or completely impregnated and provided with an outer coating. The fibrous material is preferably flexible so that the final product is soft. Stockirette, for ample, may be completely or partially impregnated and used as an interliner having an outer cover. Alternatively, the outer covering material may be back-coated with the flameretardant mixture.
The invention will now be further described by means of example.
An aqueous dispersion of powdered polyvinylidene chloride (Saran 506 (Dow), 500 parts by weight), antimony pentoxide (10 parts w/w), methocel thickener (0.5 parts w/w) and ethylene vinyl acetate/natural latex mixture (containing 60 parts EVA to 40 parts compounded natural latex; 100 parts by dry weight) was applied to polyurethane foam to a depth of 4 mm and at a coverage of 180230 gm-2. The compounded natural latex may contain ingredients including soap, zinc oxide, accelerators (e.g. zinc diethyl dithiocarbamate, zinc salt of mercaptobenzthiazole), antioxident, sulphur and potassium hydroxide. Pre-vulcanised natural latex may be used alternatively. The dispersion may contain 38% w/w of total solids but this percentage is not essential.
The resultant material was covered with an acrylic cover fabric (Draylon Registered Trade Mark) and was found to pass the butane gas flame text BS 5852 Pt 1. The properties of the material were compared to those of polyurethane foam which had been treated with fire retardant dispersions which were not in accordance with the invention.
The first comparative example comprised a dispersion of polyvinylidene chloride copolymer/terpolymer latex (Viclan 821, ICI Ltd., 85 parts w/w), antimony pentoxide (15 parts w/w), zinc oxide (5 parts w/w).
The second comparative example comprised polyvinylidene chloride film forming latex (Polidene 33/004, 100 parts w/w), antimony pentoxide (10 parts w/w), methocel thickener (0.5 parts w/w).
The properties of the examples and of untreated foam are shown in Table 1.
