Embodiment 1

[0058] Add 16.4kg of polytetrahydrofuran ether glycol (number average molecular weight: 100), 8.2kg of ethylene glycol and 35.4kg of adipic acid to the reaction kettle in sequence, turn on the stirring, start to raise the temperature, keep the temperature at 120°C for 2 hours, and dehydrate stably speed (through the distillation tower, the temperature at the top of the tower is maintained at 90°C), and then continue to increase the temperature. When the temperature rises to 160°C, the nitrogen is switched from the lower part, and the amount of nitrogen is gradually increased for dehydration. Raise the temperature to 210°C, add 2.4g of tetraisopropyl titanate after keeping the temperature for 2 hours, and start vacuuming for transesterification, take a sample every 2 hours for central control analysis within 4 hours from the start of vacuuming, until the acid value is less than or equal to 0.5mgKOH / g, hydroxyl value 37.4 mgKOH / g, return to normal pressure, switch the upper part ...

Embodiment 2

[0060] Add 11.5kg of polytetrahydrofuran ether glycol (number average molecular weight: 400), 15.3kg of ethylene glycol and 33.2kg of adipic acid to the reaction kettle in sequence, turn on the stirring, start to raise the temperature, keep the temperature at 150°C for 1 hour, and dehydrate stably speed (through the distillation tower, the temperature at the top of the tower is maintained at 100°C), and then continue to increase the temperature. When the temperature rises to 190°C, the nitrogen is switched from the lower part, and the amount of nitrogen is gradually increased for dehydration. Raise the temperature to 240°C, add 5.4g of tetraisopropyl titanate after keeping the temperature for 1 hour, and start vacuuming to perform transesterification, and take a sample every 2 hours from the beginning of vacuuming for 4 hours for central control analysis until the acid value is less than or equal to 0.5mgKOH / g, hydroxyl value 28.0mgKOH / g, return to normal pressure, switch the u...

Embodiment 3

[0062] Add 14.6kg of polytetrahydrofuran ether glycol (number average molecular weight: 800), 14.6kg of ethylene glycol and 30.8kg of adipic acid to the reaction kettle in sequence, turn on the stirring, start to raise the temperature, keep the temperature at 150°C for 1 hour, and dehydrate stably speed (through the distillation tower, the temperature at the top of the tower is maintained at 100°C), and then continue to increase the temperature. When the temperature rises to 180°C, the nitrogen is switched from the lower part, and the amount of nitrogen is gradually increased for dehydration. Raise the temperature to 230°C, add 9.6g of tetraisopropyl titanate after keeping the temperature for 1 hour, and start vacuuming for transesterification, take a sample every 2 hours for central control analysis within 4 hours from the start of vacuuming, until the acid value is less than or equal to 0.5mgKOH / g, hydroxyl value 18.7mgKOH / g, return to normal pressure, switch the upper part o...

Abstract

The invention discloses a non-slip polyurethane elastomer stock solution as well as a preparation method and application thereof. The non-slip polyurethane elastomer stock solution comprises a polyurethane stock solution component A and a polyurethane stock solution component B, wherein the polyurethane stock solution component A comprises polyether ester diol and polyester polyol; the polyurethane stock solution component B comprises hydroxy-terminated liquid rubber modified polyester polyol. The non-slip polyurethane elastomer stock solution can be applied to safety protection soles, non-slip mats and the like, and the safety protection effect is improved.

Description

technical field [0001] The invention relates to a polyurethane elastomer stock solution, a preparation method and application thereof. Background technique [0002] Polyurethane is a polymer with repeating structural units of urethane segments produced by the reaction of isocyanates and polyols. Compared with ordinary rubber soles, polyurethane soles have the characteristics of light weight and good wear resistance. The polyurethane sole uses polyurethane stock solution as the main raw material, which solves the problems that the current domestic plastic soles and recycled rubber soles are easy to break and the rubber soles are easy to peel off. By adding various additives, the polyurethane sole has been greatly improved in terms of wear resistance, oil resistance, electrical insulation, antistatic and acid and alkali resistance. However, due to the characteristics of polyurethane materials, its anti-slip performance has always been a barrier to hinder the deep and wide ap...
