Definitions
- the invention relates to the use of cellular to massive molded plastics made of polyether PUR TZU ⁇ manufacture of safety clothing, preferably safety sole.
- molded plastics based on polyurethane have been part of the long-known state of the art for decades. These molded plastics can be manufactured in a wide range of density and hardness for different applications, e.g. as protective clothing.
- the polyurethane is mainly used for protective clothing as a protective shoe. Due to existing standards (EN 344 ff), which prescribe the structure and properties of safety shoes, the choice of material has so far been restricted to the use of polyester PUR. The main reason for the rejection of polyether PUR is the insufficient resistance to oil and petrol (EN 344 point 4.8.9 fuel resistance).
- polyester-PUR or the components necessary for its production in the reaction injection molding process have the disadvantages mentioned below:
- polyester-PUR Low cold flexibility of standard polyester PUR
- polyether-PUR according to the reaction casting process or reaction spraying process, like the polyester-PUR processing, is part of the state of the art. Both in single-layer and two-layer molded sole and direct soling processes for the production of street, leisure and sports shoes, polyester-PUR is used in the density and hardness ranges, which vary depending on the requirements.
- the invention relates to the use of cellular to solid molded plastics based on polyether by foam molding for the production of safety clothing.
- the fuel resistance is achieved with outsole densities of> 800 kg / m 3 with the polyester-PUR system raw materials mentioned below as examples.
- Cellular to solid molded plastics based on polyether-polyurethane are produced by foaming a reaction mixture, e.g. out
- the starting materials are reacted while maintaining an isocyanate index of 70 to 130.
- the higher molecular weight polyether polyol component a) has a hydroxyl functionality of 2.00 or is essentially a mixture with an average hydroxyl functionality of 2.02 to 2.95
- the polyisocyanate component b) is an isocyanate group-containing prepolymer with an NCO content of 10 to 25% by weight, produced by
- -% ethylene oxide based on the weight of the polyether triol and / or a polyester component of the hydroxyl range from 28 to 115 and an average functionality of 2.0 to 2.5, wherein optionally the component (i) before the reaction or Reaction product, with polypropylene glycols in the molecular weight range 134 to 700 and / or 4,4'-diisocyanatodiphenylmethane liquefied by carbodiimidization of part of the isocyanate groups in an amount of up to 10% by weight, based on the weight of component (i) .
- Component c) is 1,2-ethanediol and / or 1,4-butanediol and / or
- component d) optionally water and / or a physical blowing agent, for example R 134 a® (hydrofluoroalkane mixture) is used.
- a physical blowing agent for example R 134 a® (hydrofluoroalkane mixture) is used.
- the activators e) are the compounds known per se from polyurethane chemistry, for example tert. Amines such as triethylenediamine, N, N-
- Dimethylbenzylamine or organic tin compounds such as dibutyltin dilaurate or tin (II) octoate.
- auxiliaries and additives f) to be used include surface-active substances, foam stabilizers, cell regulators, internal release agents, dyes, pigments, hydrolysis protection agents, fungistatic and bacteriostatic substances, light stabilizers, antioxidants and antistatic agents (quaternary ammonium compounds).
- the polyurethanes are produced in accordance with the known prior art. This generally means that components a) and c) to f) are combined to form a "polyol component" and are reacted with one another in one stage with the polyisocyanate component b) in a closed form, for example a closed metal or plastic form, whereby the usual two-component mixing units are used.
- a closed form for example a closed metal or plastic form
- Blowing agents eg R 134 ® are dimensioned so that molded foams with a bulk density of> 800 kg / m 3 result.
- Their main area of use is in shoe manufacture, according to the invention from cellular to solid outsoles for safety shoes. These preferably have an outsole bulk density> 800 kg / m 3 and, in a special embodiment, are connected to a midsole with a bulk density> 400 kg / m. Examples
- test plates measuring 20 x 20 x 1 cm were removed.
