摘要:
The present invention relates to a formulation comprising: i) an aqueous polymer dispersion comprising: a) at least one homo- or copolymer P containing in the form of polymerized units at least one ethylenically unsaturated monomer; b) at least 6% by weight, based on the total of the ethylenically unsaturated monomer, of at least one saccharide-compound S; wherein in a) the at least one homo- or copolymer P is obtained by polymerization of the at least one ethylenically unsaturated monomer in the presence of at least a part of the at least one saccharide-compound S from b); ii) at least one tackifier.
摘要:
The invention relates to a gluing composition, especially for insulating products containing mineral wool, especially glass wool or rock wool, comprising at least one non-reducing saccharide, at least one hydrogenated saccharide, and at least one polycarboxylic organic acid. The invention also relates to the resulting insulating products containing mineral fibres.
摘要:
Provided are a composition from which a biomass material can be obtained with low energy through a simple process and facility, a formed body obtained from the composition, and a method for producing the formed body. A composition according to the present invention is a composition to be cured by applying heat/pressure thereto, the composition including an element in the form of powder or small pieces, and 8% by weight or more of condensed tannin and 8% by weight or more of a saccharide selected form the group consisting of a monosaccharide and an oligosaccharide. The saccharide is preferably sucrose, glucose, fructose, maltose, xylose, or lactose. Preferably, the composition further includes an acid catalyst.
摘要:
The present invention relates to an aqueous binder for a fibre mat, in particular inorganic fibre mat, which comprises, in parts by weight: 20 to 95 parts of at least one lignosulphonic acid salt; 5 to 80 parts of at least one oligosaccharide; and 5 to 20 parts of a crosslinking catalyst chosen from phosphorus-containing compounds and sulphates for 100 parts of lignosulphonic acid salt and oligosaccharide. The subject matter of the present invention is also the products resulting from the treatment of the fibres, in particular inorganic fibres, with the abovementioned binder.
摘要:
Polysaccharide thermosetting systems and composites utilizing such systems include formaldehyde free binders formed from at least one polysaccharide and at least one polysaccharide crosslinker.
摘要:
The purpose of the present invention is to provide a bonding composition having high adhesion, from which formaldehyde is hardly released. The present invention relates to a bonding composition cured through heating and pressing. The bonding composition contains a polyvalent carboxylic acid.
摘要:
The present invention relates to a binder for a mat of fibres, in particular inorganic fibres, which includes: at least one monosaccharide and/or at least one polysaccharide, at least one polycarboxylic organic acid having a molar mass of no greater than 1000, and at least one homopolymer or vinyl-acetate copolymer. The invention also relates to the products that result from treating fibres, in particular inorganic fibres, with the aforementioned binder.
摘要:
A hydrogel tissue adhesive having decreased degradation time is described. The hydrogel tissue adhesive is formed by reacting an oxidized polysaccharide with a water-dispersible, multi-arm polyether amine in the presence of an oligomer additive, which promotes the degradation of the hydrogel. The hydrogel may be useful as a tissue adhesive or sealant for medical applications, such as a hemostat sealant or to prevent undesired tissue-to-tissue adhesions resulting from trauma or surgery.
摘要:
The invention relates to a particulate binding agent composition comprising at least one natural or synthetic polysaccharide and at least one synthetic water dispersible polymer. The amount of particles having a diameter of less than 30 νm is less than 1 wt. % and the free fibre content in 5mg of the binding agent composition is at least 40. The invention also relates to a method for the production and the use thereof.
