Embodiment 1

[0018] Embodiment 1: a kind of preparation method of nylon elastomer material, its method is as follows:

[0019] With 5kg nylon 1012 salt monomer, 1kg softening agent dimer acid, 0.2kg end-capping agent dodecyl diamine and auxiliary agent namely 10g catalyst sodium ethylate and ammonium salt i.e. dodecyltrimethylammonium chloride, resist Add oxygen agent 1098, heat stabilizer HT-26, heat stabilizer CS-181, and 2kg of solvent water into the polymerization kettle, stir at a speed of 40r / min, raise the temperature to 240°C, and pressure to 1.5MPa, react for 2 hours, and drop to normal Then keep the negative pressure to -0.1MPa for 2 hours. The alcohol produced by condensation during polymerization is recovered through rectification and three-stage condensation, and finally pressurized and extruded, cooled, granulated or diced, dried, and packaged. After granulation or granulation, the unqualified products after screening are returned to the polymerization kettle, and vacuum dryi...

Embodiment 2

[0021] A kind of preparation method of nylon elastomer material, its method is as follows:

[0022] With 5kg nylon 1012 salt monomer, 1kg softening agent polytetramethylene glycol, 0.9kg end-capping agent dodecane dibasic acid and auxiliary agent namely 15g catalyst magnesium chloride, 10g antioxidant 1098 and heat stabilizer HT-181, 2kg water Add to the polymerization kettle, stir at the speed of 40r / min, raise the temperature to 240°C, and the pressure to 1.5MPa, react for 2h, drop to normal pressure, then vacuumize to negative pressure -0.1MPa, continue for 2h, and condense the alcohol produced during polymerization Alcohol is recovered through rectification and three-stage condensation, and finally pressurized and extruded, cooled, granulated or diced, dried, packaged, and unqualified products after granulated or diced are returned to the polymerization kettle, and vacuum drying is used for drying , to obtain the final finished nylon elastomer material.

Embodiment 3

[0024] A kind of preparation method of nylon elastomer material, its method is as follows:

[0025] 5kg nylon 1012 salt monomer, 0.8kg softening agent double-ended hydroxypolytetramethyl ether, 0.5kg end-capping agent adipic dibasic acid and auxiliary agent, namely 15g catalyst sodium ethylate, 10g antioxidant 1098 and heat stabilizer Add HT-26, 2kg of water into the polymerization kettle, stir at a speed of 40r / min, raise the temperature to 240°C, and the pressure to 1.5MPa, react for 2h, drop to normal pressure, and then evacuate to negative pressure -0.1MPa for 2h , the alcohol produced by condensation during polymerization is recovered through rectification and three-stage condensation, and finally pressurized and extruded, cooled, granulated or granulated, dried, packaged, and unqualified products are screened and returned to polymerization after granulated or granulated Still, drying adopts vacuum drying to obtain the final finished nylon elastomer material.

Abstract

The invention relates to a nylon elastomer material and a preparation method thereof. The nylon elastomer material is composed of the following components in parts by mass, wherein the mass ratio of anylon 1012 salt monomer to a softener to an end-capping reagent is 100:(10-30):(0.1-0.5), and the softener is any one or a combination of more of polybutylene glycol, dimer acid, polyester and polyether; long-carbon-chain decamethylene diamine and aliphatic dodecanedioic acid are used as main raw materials for synthesizing the nylon 1012 salt monomer; the characteristics of good flexibility and high benzene ring rigidity of long-carbon-chain nylon are combined; the nylon matrix resin has relatively good flexibility and crystallinity; the temperature resistance, the alcohol resistance and theoil resistance are good; copolymerization is carried out under a proper reaction condition by using the softener; meanwhile, the active stable polymerization of end groups is eliminated by the end-capping reagent, and the thermal stability, the oxidation resistance and the catalytic activity are improved by the aid of the auxiliaries, so that on one hand, the hardness of nylon is reduced, and thematerial feels soft, and on the other hand, the material can be conveniently used for manufacturing foaming base materials of sneaker soles, is lighter and can be widely used.

Description

technical field [0001] The invention relates to a nylon elastomer material and a preparation method thereof, belonging to the technical field of nylon materials. Background technique [0002] Polyamide, commonly known as nylon, is a general term for thermoplastic resins containing repeated amide groups on the main chain of the molecule, including aliphatic nylon, aliphatic-aromatic nylon and aromatic nylon. It has mechanical properties, heat resistance, wear resistance, and With good comprehensive properties such as chemical properties and self-lubricating properties, it can be widely used in the manufacture of sports shoe sole materials and nylon pipes. With the increasing requirement of comfortable, soft and lightweight sports shoe soles, the high hardness of nylon elastomer materials in the prior art leads to poor comfort of sports shoe soles, and it is difficult to meet the application of sports shoe sole foaming technology base materials, resulting in insufficient sport...
