Embodiment 1

[0094] Embodiment 1: the synthesis of stearyl phosphate that the degree of esterification is 1.5:

[0095] While stirring and introducing N 2 While heating stearyl alcohol (≥95%, 212.8g, 0.787mol) to 70°C, add P in small batches 4 o 10 (37.23 g, 0.131 mol), so that the temperature of the reaction mixture does not rise above 80 °C. at P 4 o 10 After the addition of , after the introduction of N 2 The reaction mixture was stirred at 80° C. for 3 hours until the acid value was constant. After decanting and cooling, a colorless solid with an acid value of 164 mgKOH / g was obtained.

Embodiment 2

[0096] Embodiment 2: the synthesis of stearyl phosphate that the degree of esterification is 1.8:

[0097] While stirring and introducing N 2 While heating stearyl alcohol (≥95%, 174.7g, 0.646mol) to 70°C, add P in small batches 4 o 10 (25.45 g, 0.0896 mol), so that the temperature of the reaction mixture does not rise above 80 °C. at P 4 o 10 After the addition of , after the introduction of N 2 The reaction mixture was stirred at 80° C. for 3 hours until the acid value was constant. After decanting and cooling, a colorless solid with an acid number of 139 mg KOH / g is obtained.

Embodiment 3

[0098] Embodiment 3: the synthesis of stearyl phosphate that the degree of esterification is 2.2:

[0099] While stirring and introducing N 2 While heating stearyl alcohol (≥95%, 178.7g, 0.661mol) to 70°C, add P in small batches 4 o 10 (21.31 g, 0.0751 mol) so that the temperature of the reaction mixture does not rise above 80°C. at P 4 o 10 After the addition of , after the introduction of N 2 The reaction mixture was stirred at 80° C. for 3 hours until the acid value was constant. After decanting and cooling, a colorless solid with an acid number of 127 mg KOH / g is obtained.

Abstract

The invention relates to use of long-chain phosphoric acid esters in aqueous polyurethane dispersions. The use of long-chain phosphoric acid esters as additives in aqueous polymer dispersions for production of porous polymer coatings, preferably for production of porous polyurethane coatings, is described.

Description

technical field [0001] The invention belongs to the field of plastic coating and artificial leather. Background technique [0002] More specifically, the present invention relates to the use of long-chain phosphate esters as additives to produce porous polymeric coatings, especially porous polyurethane coatings. [0003] Plastic-coated textiles, such as artificial leather, generally consist of a textile support on which is laminated a porous polymer layer, which in turn is coated with a top layer or top coat. [0004] In this case, the porous polymer layer preferably has pores in the micron range and is air-permeable and thus breathable, ie permeable to water vapour, but waterproof. The porous polymer layer typically comprises porous polyurethane. For the environmentally friendly production of PU-based artificial leather, a method based on aqueous polyurethane dispersions, known as PUDs, has recently been developed. These dispersions usually consist of polyurethane microp...
