The present invention is directed to a method for producing oxidized lignins.

Method for producing oxidized lignins

Described is an aqueous binder composition for mineral fibers which comprises a component (i) in the form of one or more carbohydrates and a component (ii) in the form of one or more compounds selected from sulfamic acid, derivatives of sulfamic acid, salts thereof.

Binder

The invention relates to an aqueous binder composition for mineral fibers comprising a component (i) in the form of one or more compounds selected from &#x2014;compounds of the formula, and any salts thereof. In which R1 corresponds to H, alkyl, monohydroxyalkyl, dihydroxyalkyl, polyhydroxyalkyl, alkylene, alkoxy, amine; &#x2014;compounds of the formula, and any salts thereof. In which R2 corresponds to H, alkyl, monohydroxyalkyl, dihydroxyalkyl, polyhydroxyalkyl, alkylene, alkoxy, amine; a component (ii) in the form of one or more compounds selected from the group of ammonia, amines or any salts thereof; a component (iii) in the form of one or more carbohydrates. 

Biobinder

The invention provides a method of growing plants in a mineral wool growth substrate, the method comprising:

Method of growing plants

Process for providing a binder for mineral wool products, said process comprising the steps of: mixing together under reactive conditions a carboxylic acid with an alkanolamine, whereby optionally these are firstly mixed to provide a resin, which resin is subsequently reacted with a separate carboxylic acid group containing polymer.

Binder for mineral wool products

Process for providing a binder for mineral fibers, comprising the steps of: mixing together under reactive conditions an amine and an anhydride whereby water is added thereto, once substantially all the anhydride is dissolved and/or reacted in the amine.

Resin for a binder suitable for mineral fibers such as glass or stone wool, said resin comprising the reaction product of a polymer free mixture of an amine with a first anhydride and a second anhydride, characterized in that the first and second anhydrides are different anhydrides.

Resin for a mineral wool binder comprising the reaction product of an amine with a first and second anhydride

Mineral fiber products, in particular rigid bonded mineral fiber products, are provided which comprise composite mineral fibers having a coating-core configuration wherein the core provides at least 90% by weight of the fibers and is formed of mineral melt and the coating is coated onto the core. The mineral melt is chosen so that the fibers without coating have adequate biological solubility and the coating comprises a phosphate or hydrogen phosphate of alkali metal, quaternary ammonium or ammonium in an amount of at least 0.3% or by weight of the core. The coated fibers retain their biological solubility while improving resistance to ageing in use.
