Embodiment 1

[0014] In a clean and dry composite kettle equipped with a condenser, add methyl isobutyl ketone (243g) solvent and MDI-TMP.C prepolymer (755g), heat up to 40-60°C, stir at high speed, dissolve and set aside , Dissolve the measured cationic antistatic agent SN (68g) and antioxidant BT-ZME (45g) in methyl isobutyl ketone (38g), transfer to the addition funnel, and add it dropwise under high-speed stirring at 40-60°C In the compounding kettle, keep the temperature constant for 1 hour, cool down to normal temperature, discharge and pack.

Embodiment 2

[0016] In a clean and dry composite kettle equipped with a condenser, add methyl isobutyl ketone (493g) solvent and MDI-TMP.C prepolymer (507g), heat up to 40-60°C, stir at high speed, dissolve and set aside , Dissolve the metered cationic antistatic agent SN (68g) and antioxidant BT-ZME (45g) in methyl isobutyl ketone (113g), transfer to the addition funnel, and add it dropwise under high-speed stirring at 40-60°C In the compounding kettle, keep the temperature constant for 0.5 hours, cool to normal temperature, and pack the materials.

Embodiment 3

[0018] In a clean and dry composite kettle equipped with a condenser, add methyl isobutyl ketone (243g) solvent and MDI-TMP.C prepolymer (755g), heat up to 40-60°C, stir at high speed, dissolve and set aside , Dissolve the metered cationic antistatic agent DM3726 (78g) and antioxidant BT-ZME (45g) in methyl isobutyl ketone (41g), transfer to the addition funnel, and add it dropwise under high-speed stirring at 40-60°C In the compounding kettle, keep the temperature constant for 1.5 hours, cool down to normal temperature, discharge and pack.

[0019] In Examples 1-3, the MDI-TMP.C prepolymer was prepared in the following way: (1) At 30°C-70°C, the measured amount of TMP was fully dissolved in the organic solvent methyl isobutyl ketone to obtain liquid A ; Dissolve MDI in the organic solvent methyl isobutyl ketone, and add a catalytic amount of dibutyltin dilaurate or stannous chloride dropwise to obtain liquid B; (2) After raising the temperature of liquid A to 40-150°C, Add l...

Abstract

The invention discloses a novel antistatic bridging agent. A preparation method of the bridging agent comprises the following steps: firstly, adding metered organic solvents including methyl isobuthyl ketone and an MDI-TMP (diphenyl-methane-diisocyanate-trimethylolpropane).C prepolymer to a mixing reactor, then raising the temperature to 40-60 DEG C and dissolving the organic solvents for later use under high-speed stirring; and secondly, dissolving metered cationic antistatic agents and antioxidant in methyl isobuthyl ketone, dropwise adding the solution to the mixing reactor under high-speed stirring at 40-60 DEG C after transferring the solution to a charging hopper, preserving heat for 0.5-1.5 hours at 40-60 DEG C after completing dropwise adding, then cooling the product to normal temperature and packaging the product, thus obtaining the bridging agent. The novel antistatic bridging agent has the following beneficial effects: the special cationic antistatic agents are introduced into the MDI-TMP.C prepolymer, thus making up for the defect of poor antistatic property in the process of high-speed spinning; and meanwhile, the bridging agent has the properties such as heat proofing, smoothing, wetting, saturation, oil film strength, sizing and the like and is suitable for high-speed spinning of polyester semi-dull, super bright and foreign fibers.

Description

technical field [0001] The invention relates to a novel antistatic bridging agent, in particular to a compound method to synthesize a novel antistatic bridging agent. Background technique [0002] With the continuous development of polyester chemical fiber production and processing technology in recent years, polyester polymers have low hygroscopicity, poor antistatic performance, and large friction coefficient in the high-speed spinning process of polyester. It is very easy to produce wool and broken ends during the silking process, which greatly reduces the fiber performance, and the demand for related bridging agents is also increasing rapidly. At present, the industrialization of domestic bridging agents has not achieved great development. High-quality, high-performance The production of bridging agents cannot meet the needs of large-capacity polyester fiber production and high-speed spinning processing, and the demand of major polyester fiber manufacturers still depends...
