Abstract:
L'invention concerne une composition adhésive aqueuse comprenant comme composante adhésive principale un ester de silicate obtenu par réaction entre une protéine, un polysaccharide et un métasilicate alcalin, la protéine comprenant un ou plusieurs de chacun des acides aminés suivants : sérine, thréonine et lysine et le polysaccharide comportant des groupements carboxyliques (-COOH) et/ou des groupements sulfoniques (-SO 3 H), ainsi que sa fabrication et son utilisation.
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.
Abstract:
An aqueous adhesive composition and a process for preparing such compositions are disclosed. The composition comprises macromolecular complex comprising (A) a first component comprising (i) a framework element and (ii) a polyphenol, and (B) second component comprising a polypeptide, oligopeptide, amino acid, or polyamine. The 5 framework element comprises (a) a polypeptide, oligopeptide, amino acid, or polyamine, (b) a polysaccharide, oligosaccharide, or monosaccharide, or a saccharide conjugate, or (c) a lignin, a lignan or a lignin conjugate. The polyphenol comprises a tannin, a tannic acid, a flavonoid, or a poly-resorcinol. An adhesive precursor composition comprising the first component is also disclosed.

Abstract:
An environmentally friendly, bio-based binder system that is useful for the formation of fiberglass insulation, the system includes: A) an aqueous curable binder composition, which includes a carbohydrate and a crosslinking agent; and B) a dedust composition, which includes a blown, stripped plant-based oil and optionally at least one emulsifying agent. The bio-based binder system is typically heated to form a cured binder system.
Abstract:
Beschrieben wird eine Zusammensetzung, basierend auf von Industrieresten bei der Bearbeitung von Früchten, insbesondere der Äpfel stammende Produkte. Die Zusammensetzung vegetale Produkte umf asst, getrocknetes Apfelmehl, stammend von Industrieresten bei der Bearbeitung von Früchten, insbesondere von Äpfeln.
Abstract:
An environmentally friendly, formaldehyde-free, aqueous binder composition that includes a carbohydrate, a crosslinking agent, and a pre-reacted product of an alcohol or polyol and monomeric or polymeric polycarboxylic acid or polyglycerol is provided. The pre-reacted product may include glycerol and esters of citric acid such a monoglyceryl citrate, diglyceryl citrate, and triglyceryl citrate as well as other higher molecular weight citric acid-based esters. The inclusion of the pre-reacted product in the binder composition helps to speed the crosslinking reaction, induces faster water evaporation, decreases the viscosity of the binder, helps to reduce the amount of water needed for application of the binder, decreases tackiness, and helps to achieve a maximum vertical expansion of the insulation pack in the transfer zone. The binder composition may be used in the formation of insulation materials and non-woven chopped strand mats.
