US Classification:

442327, 527300, 527312, 527311, 527200

Abstract:

An aqueous binder composition is provided that includes a modified starch and a silane coupling agent, and optionally, a crosslinking agent. The starch from which the modified starch is derived is natural in origin, biorenewable, and is derived from plant sources. The modified starch has been chemically modified from its natural form and may have a degree of polymerization from about 20 to about 4000. Additionally, the modified starches have a low viscosity and cure at moderate temperatures. Advantageously, the modified starches are water dispersible and have excellent resistance to water after curing. In addition, the binder has a light color after being cured. The crosslinking agent may be any compound suitable for crosslinking the starch based compound. In exemplary embodiments, the silane coupling agent is an aminosilane. The environmentally friendly, biorenewable binder may be used in the formation of insulation materials and non-woven chopped strand mats.

Abstract:

An aqueous binder composition is provided that includes a carbohydrate and a crosslinking agent. In exemplary embodiments, the carbohydrate-based binder composition may also include a catalyst, a coupling agent, a process aid, a crosslinking density enhancer, an extender, a moisture resistant agent, a dedusting oil, a colorant, a corrosion inhibitor, a surfactant, a pH adjuster, and combinations thereof. The carbohydrate may be natural in origin and derived from renewable resources. Additionally, the carbohydrate polymer may have a dextrose equivalent (DE) number from 2 to 20. In at least one exemplary embodiment, the carbohydrate is a water-soluble polysaccharide such as dextrin or maltodextrin and the crosslinking agent is citric acid. Advantageously, the carbohydrates have a low viscosity and cure at moderate temperatures. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats. A method of making fibrous insulation products is also provided.

International Classification:

B29C 47/92
G01N 33/00

US Classification:

264 401, 73159

Abstract:

A method for assessing the cure status of a fibrous blanket manufactured with mineral fibers and binder is disclosed and comprises a first, qualitative assessment of cure followed by a second quantitative assessment that utilizes one of alternative procedures depending on the outcome of the first, qualitative assessment. For example, a first visual inspection may qualitatively reveal areas or undercure, upon which a second pH test of samples extracted from undercured areas may quantify the degree of undercure. Conversely, if the visual inspection reveals no undercured areas, a different sampling procedure examines different blanket areas for overcure status using a similar pH test.

US Classification:

264128, 264129

Abstract:

Fibrous insulation products manufactured with surfactants and methods for making are disclosed. The surfactant may be neutral or charged and, if charged, may be anionic, cationic or zwitterionic, although neutral or non-ionic provide suitable results. The surfactant may be of any chemical structure class, although ethoxylated alcohols and ethoxylated ethers have been found most suitable. Surfactant may be sprayed onto mineral fibers as a separate dispersion or as part of a binder dispersion. The surfactant my optionally be used with an organo-silane coupling agent, such as an amino-silane.
