Description
SPECIFICATION
Flame retardant compositions and methods of preparing same
The present invention relates to both aqueous-based and organic-based compositions for use in imparting flame retardant properties to a variety of materials including cellulosic materials, such as paper, cotton fabrics and wood, and also to polymeric materials, such as fabrics and films made from synthetic polymers.
It is well known in the art that the flame retardant properties of flammable materials can be improved by coating the materials with flame retardant agents or by incorporating into the article itself a flame retardant substance. Literally thousands of flame retardant compositions and agents have been described in the literature, but in view of the importance of this technology, compositions offering improvements in properties continue to be investigated.
In particular, attention has been directed to producing flame retardant compositions which increase the resistance of an article to combustion upon the direct application of flame and at the same time do not deleteriously effect other desired properties of the article, such as strength, physical appearance and handling, absorption and like properties.
Applicant has now developed a series of compositions capable of improving the flame retardancy of articles made from both natural and synthetic materials without serious deterioration in properties of the articles and, in some cases, with increase in certain important properties.
The present invention seeks to provide compositions capable of imparting improved flame retardancy to a variety of articles.
The present invention also seeks to provide compositions for improving fire and flame retardancy of articles while at the same time not adversely effecting the desirable properties of the articles to any substantial degree.
The present invention further seeks to provide compositions for improving the resistance of articles to combustion upon the direct application of flame, as well as methods for preparing flame
retardant compositions having the above-mentioned advantages.
The invention generally comprises the provision of both aqueous-based and organic-based flame retardant compositions useful in the coating of a variety of substrates and/or in the direct incorporation into manufactured articles so as to improve the flame retardancy of the articles without substantially diminishing the original properties and characteristics of the articles.
As to all of the flame retardant compositions within the scope of the present invention which will be described below, it is important to note that their toxicity index is negligible and that their odor is not unpleasant. These characteristics are important since the products treated with the instant compositions are products which are likely to be utilized in the household, places of public accommodation, vehicles and the like where non-toxicity towards humans and favorable esthetic characteristics are highly desirable.
I. Aqueous-based composition especially adapted for application to cellulosic articles
In accordance with the present invention, applicant has developed the following compositions particularly suited to the improvements of flame resistance in articles made in whole or in part from cellulosic substances, such as wood, paper, cotton and the like.
The preferred formulations are as follows:
Compound No. Ingredient Amount 1 Thiethanolamine Lauryl Sulphate 0.56.0% by volume (5-6 ml/l)
2 Ammonium lodide 2.0-7.0 parts by
weight (PBW)
3 Ammonium Monophosphate 1.5-8.0 PBW
4 Ammonium Bromide 2.0-12.0 PBW
5 Borax or Sodium Tetraborate 1.5-20.0 PBW
6 Boric Acid 1.5-7.0 PBW
7 Ammonium Sulphate 3.5-20.0 PBW
8 Sodium Silicate 0.11.0% by volume (1-10 mIll)
9 1,2 Propylene Glycol 1.510.0% by volume (1 5-100 ml/l)
10 Water 84.0--180 PBW
(3.5 It7.5 It)
Certain ingredients may also be added optionally to impart bactericidal and fungicidal properties to the compositions. By way of example, such additives may include acromicine, undecilenic acid and zinc undecilinate.
A particularly preferred composition within the scope of the above formulation is as follows:
Compound No. Ingredient Amount 1 Triethanolamine Lauryl Sulphate 2.0% by volume
2 Ammonium iodize 3.5% PBW 3 Ammonium Monophosphate 7.0% PBW
4 Ammonium Bromide 3.0% PBW
5 Borax 2.0% PBW
6 Boric Acid 4.0% PBW
7 Ammonium Sulphate 12.0% PBW 8 Propylene Glycol 3.3% by volume
9 Sodium Silicate 0.5% by volume
10 Acromicine 2.0% PBW
11 Undecilenic Acid 1.0% PBW
12 Zinc Undecilinate 0.5% PBW
13 Water 120.0% PBW
In preparing the compositions as described above, it has been found to be important to follow a particular procedure.The following method should be employed:
Step 1
Referring to the particularly preferred composition, compounds 2, 3, 4, 5, 6 and 7 are mixed togethertoform a homogeneous mixture.
Step 2
Compounds 10, 11 and 12 are mixed together to form a homogenexus mixture.
Step 3
To the product of Step 1, a portion of the water sufficient to dissolve the compounds e.g., 50% of the total water, is added and the composition is heated to 700C with agitation continuously until the solids are dissolved. It is important to mention that the dissolution temperature of these ingredients should not exceed about 70 C in order to avoid the loss of molecular water in the boric acid which could yield metaboric or tetraboric acid, depending upon the temperature. Maintenance of the temperature below 700C is also important to prevent the boric acid from crystallizing.
Step 4
To one liter of the product of Step 3, there are added the compounds 9 and 1 plus the balance of the water. At this stage, the mixture of compounds 10, 11 and 12 from Step 2 is also added. The mixture is then cooled to below about 21 0C, and compound 8 is added.
In utilizing the foregoing compositions, they may be applied in any conventional fashion to the surface of materials for the purpose of improving the flame retardancy of such materials. As earlier noted, the foregoing compositions are particularly suited to production of cellulosic articles of improved flame retardancy. Coating might be done by immersion of the article, spraying, painting, roller coating or otherwise surface coating the article. It is also possible that the composition might be incorporated into the article such as paper, by being added at one of the final stages of paper production, certainly at a stage beyond the point at which the composition might be washed-out or diluted.
When applied to paper and textiles, the foregoing composition surpasses the standards of the
A.S.T.M. and N.F.P.A. with respect to combustion testing.
Besides improving fire retardancy, the particularly preferred compositions which incorporate the anti-bacterial and anti-fungal agent also have been found to increase the physical properties of cellulosic materials to which they are applied.
After treatment, substrate materials subjected to standard laboratory tests showed the following properties.
Sample 1
A 5 g piece of paper was treated with 20%, by weight, of this product on a dry basis. The original paper characteristics were affected as follows: 1. Strength
a. Tensile strength-increased by 20%.
b. Loosen strength-increased by 10% (the rupture strength of the fabric).
C. Weathering normal oxidation not affected.
d. Absorption-unchanged.

8. Indirect heat application
Paper carbonizes in an oven at 541 .20F without flame.
Sample 2
A fabric swatch of cotton fiber containing a maximum of 40% synthetic fibers was treated with 2030%, by weight, on a dry basis, of the fire retardant composition. The original characteristics of the fabric were affected as follows: 1. Strength
a. Tensile strength-increased by 30%.
b. Abrasion strength-increased by 10%.
c. Durability-increased from 5-1 5%.
d. Weathering-not affected under the same conditions as the untreated fabric.
2. Physical characteristics
a. Roughness-slightly increased.
b. Brightness-not changed.
3. Permeability and/or absorption
No important changes.
4. Reaction to colorarits
Not affected in appearance, but colorants settled by 15%.
5. Utilities
a. Printability-cloth printings are not altered. Detergent action on the printed cloth does not affect the fiber or its appearance.
b. Abrasion resistance-increased by 20%.
c. Heat resistance-increased by from 5 to 1 5%.
6. Chemical resistance
Influence of acids, alkalis and solvents is substantially unaffected by treatment.
7. Direct flame application
The fabric carbonizes with no proliferation of the flame; when the flame is suspended, the flame disappears as does the heat.
8. Indirect heat application
Fabric carbonizes at 541 .20F without flame.
