摘要:
The present invention relates to an aqueous mixed binder composition and a method for binding fibrous materials by using the same, and more specifically, relates to an aqueous mixed binder composition comprising a) one or more reducing sugars, b) one or more amino acids, and c) one or more condensed products formed by combining amide-based compound or phenol-based compound with formaldehyde, and a method for binding fibrous materials by using the same. The aqueous mixed binder composition of the present invention provides equal or better physical properties with lower price compared to traditional phenol formaldehyde resin (PFR) used independently, its final product releases almost no toxic materials since the contents of toxic materials such as formaldehyde or phenol are decreased to ppm units, may decrease bad odor which is a weak point of traditional PFR during manufacturing and may remarkably enhance the mechanical properties-such as water resistance, tensile strength and hardness-and dust rate of the manufactured product and dust rate compared to the traditional eco-friendly resin which does not comprise toxic materials such as formaldehyde and phenol, and is economical since process water can be recycled without putrefaction due to microorganisms which occurs during the manufacturing process of fibrous materials to which it is bound by the binder composition since the binder solution has preservative ability.
摘要:
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 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.
摘要:
The present invention relates to a sizing composition for insulating products based on mineral wool, in particular of glass or of rock, which comprises - at least one saccharide, - at least one organic polycarboxylic acid, - at least one esterification catalyst, and - at least one agent capable of reducing the emissions of volatile organic compounds (VOCs) chosen from sulphates, sulphamates and carbonates. Another subject of the present invention is the insulating products based on mineral fibres obtained and the process for the manufacture thereof.
摘要:
It is aimed to provide medical-use adhesive and medical-use hydrogel resin that satisfy general requirements for such adhesive and resin and are rapidly disintegrated at an elapse of designed time period, which may be rather freely controlled or adjusted. A first liquid for the adhesive or the resin is an aqueous solution of aldehyde-groups-introduced alpha-glucan having a weight-average molecular weight in a range of 1000 to 200,000. A second liquid for the adhesive or the resin is aqueous solution of amino-groups-containing polymer that is formed of a polymer chain of amino-group-containing units and has a molecular weight in a range of 1000 to 20,000. A mixture of the first and second liquids at a time of mixing them has pH in a range of 5.0 to 8.0.
摘要:
The invention relates to aqueous adhesive dispersions containing A) 0.1-10 wt.% adhesive polymer in the form of a dispersion with respect to the overall weight of the dispersion, B) 0.1-100 parts by weight of constituent A), an anionic or cationic polyelectrolyte and C) 0-50 parts by weight in relation to the 100 parts by weight of constituents A) of at least one polyalkyleneglycol with a molar mass of 200-100,000 g/mol. The invention also relates to the use of said dispersions in the production of multi-layered paper or paper material.
