Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
63 words
A flame resistant composition which may be applied to form a coating or a lining comprising kaolin a ceramic fiber dispersed in an air-hardenable organic binder, said binder being insoluble in water after hardening and said fiber being randomly distributed throughout the binder in an amount between about 20 and 45 weight percent based on the total weight of the composition after hardening.
Claim 2
Dependent Claim
63 words
A flame resistant composition which may be applied to form a coating or a lining comprising kaolin a ceramic fiber dispersed in an air-hardenable organic binder, said binder being insoluble in water after hardening and said fiber being randomly distributed throughout the binder in an amount between about 20 and 45 weight percent based on the total weight of the composition after hardening.
Claim 3
Dependent Claim
20 words
The flame resistant composition of claim 1, wherein said kaolin fiber is present between about 25 and 30 weight percent.
Claim 4
Dependent Claim
25 words
The flame resistant composition of claim 1, wherein said kaolin fiber has a mean fiber length in the range from about 0.5 to 10 mm.
Claim 5
Dependent Claim
17 words
The flame resistant composition of claim 1, wherein said organic binder is an aqueous based organic binder.
Claim 6
Dependent Claim
21 words
The flame resistant composition of claim 5, wherein said aqueous based organic binder is a colloidial suspension of a polyvinyl material.
Claim 7
Dependent Claim
33 words
The flame resistant composition of claim 6, wherein said polyvinyl material is selected from the group consisting of polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polyvinyl acetal, polyvinyl acetate, polyvinyl butyral and mixtures thereof.
Claim 8
Dependent Claim
20 words
The flame resistant composition of claim 7, wherein said organic binder is a colloidial suspension of polyvinyl acetate in water.
Claim 9
Dependent Claim
22 words
The flame resistant composition of claim 1, wherein said binder is included in the composition between about 45 and 75 weight percent.
Claim 10
Dependent Claim
19 words
The flame resistant composition of claim 9, wherein the binder is present between about 65 and 72 weight percent.
Claim 11
Dependent Claim
11 words
The flame resistant composition of claim 1, free from flamable solvents.
Claim 12
Dependent Claim
22 words
The flame resistant composition of claim 1, further including an effective amount of an additive for increasing the flexibility of said composition.
Claim 13
Dependent Claim
19 words
The flame resistant composition of claim 11, wherein said additive is present between about 2 to 10 weight percent.
Claim 14
Dependent Claim
19 words
The flame resistant composition of claim 11, wherein said additive is present between about 2 to 6 weight percent.
Claim 15
Dependent Claim
14 words
The flame resistant composition of claim 1, further including a substantially inflammable thickening agent.
Claim 16
Dependent Claim
30 words
The flame resistant composition of claim 14, wherein said thickening agent is selected from the group consisting of powders of kaolin, asbestos, perlite, expanded mica, diatomite, plaster and mixtures thereof.
Claim 17
Dependent Claim
26 words
The flame resistant composition of claim 1, further including a component which will cause said composition to foam upon subjecting the hardened composition to elevated temperatures.
Claim 18
Independent Claim
54 words
A method for preparing a flame resistant composition which may be applied as a coating or a lining comprising forming a substantially homogeneous emulsion of an emulsifible oil in an aqueous solution of an organic binder which is air-hardenable and insoluble in water after hardening and adding and dispersing kaolin fibers into said emulsion.
Claim 19
Independent Claim
54 words
A method for preparing a flame resistant composition which may be applied as a coating or a lining comprising forming a substantially homogeneous emulsion of an emulsifible oil in an aqueous solution of an organic binder which is air-hardenable and insoluble in water after hardening and adding and dispersing kaolin fibers into said emulsion.
Claim 20
Dependent Claim
33 words
The method of claim 17, including the step of mixing powdered thickening agent for partially filling in pores and interstices present about the kaolin fibers after the composition has been applied and hardened.
