[0076] Preparation of water retaining agent

[0077] Preparation of 2-hydroxypropyl galactomannan with an average ratio of D-mannose to D-galactose units of about 1:1

[0078] In a 5-liter stirred reactor, 600 g of fenugreek gum was loaded at room temperature, the reactor was purged with nitrogen and a solution of 21 g of NaOH in 175 g of water was added with vigorous stirring. Continue stirring for 15 minutes at room temperature.

[0079] After purging again with nitrogen, 410 g of propylene oxide was added while stirring at 65-70°C for 6 hours.

[0080] The reaction mixture was cooled to 40°C and the pH was neutralized to about 5-6.5 by adding acetic acid.

[0081] The reaction mixture thus obtained was dried with hot air on a fluidized bed dryer until the moisture content was about 3% by weight, and then ground and analyzed.

[0082] The resulting product (HPF H ) MS HP = 1.5.

[0083] Preparation of 2-hydroxypropyl-2-hydroxy-3-(2-ethylhexyloxy)propyl galactomannan with an average r...

Abstract

Dry compositions comprising a hydraulic binder, such as cement or gypsum, and a highly substituted C2-C4 hydroxyalkyl galactomannan with average D-mannosyl to D-galactosyl unit ratio different from 2:1 provide pastes having good water retention characteristics and workability.

Description

Technical field [0001] The present invention relates to a dry composition comprising a hydraulic binder (such as cement or gypsum) and a water-retaining agent having a height with an average ratio of D-mannose to D-galactose units other than 2:1 Replaced C 2 -C 4 Hydroxyalkyl galactomannan, which preferably contains linear or branched C 6 -C 22 Alkyl chain. technical background [0002] In the field of construction, it is well known that hydraulic adhesive compositions are used to manufacture basic structures (such as paving tiles or slabs and tiles) of buildings, artworks, apartment buildings or products, and as adhesives or bonding compositions , Especially usually used to vertically or horizontally adhere tiles or ceramics to various surfaces, such as adhering to concrete, plywood or brick surfaces. [0003] In this article, the term "hydraulic binder" is defined as a mineral that hardens due to a hydration chemical reaction in the presence of water and can bind other materials...
