Problems solved by technology

[0003] The current nylon is basically made of petroleum derivatives as raw materials. For example, the two varieties of nylon 6 and nylon 66 with the largest market share in the nylon market, their raw materials caprolactam and adipic acid are hydrogenated and reoxidized by benzene homologues. Hexamethylenediamine is prepared by first synthesizing adiponitrile from butadiene or acrylonitrile and then by catalytic hydrogenation. The whole synthesis process is complicated and there is some pollution

Embodiment 1

[0052] Embodiment 1, Preparation of Nylon 56

[0053] The 50-liter enamel salt-forming kettle was vacuumed and filled with nitrogen to replace the air three times, and protected with nitrogen, 30kg of pure water was added to the salt-forming kettle, and then 12.46kg of pentamethylenediamine (purchased from Shandong Kaisai, containing ASTM D6866 standard organic carbon from renewable sources, gas phase normalization method purity 99.56%), start stirring, add 17.64kg of adipic acid (purchased from Liaoning Petrochemical), and then add 6g of antioxidant H10 (Bruggolen H10 German Brug Gehman Company) to prepare nylon saline solution.

[0054] Replace the air in a 100-liter polymerization kettle (K / SY166-2007 type) with nitrogen, and transfer the nylon salt solution to the polymerization kettle. The temperature of the oil bath rises to 230°C. After the pressure in the kettle rises to 1.73Mpa, start to vent. When the temperature in the kettle reaches 265°C, vacuumize to -0.06Mpa (...

Embodiment 2

[0055] Example 2 , the preparation of nylon 56

[0056] Operate in the same manner as in Example 1 except that the amount of pentamethylenediamine added in the adjustment example 1 is 12.39kg. Nylon 56 was obtained with a reduced viscosity of 120ml / g.

Embodiment 3

[0057] Example 3 , the preparation of nylon 56

[0058] Operate in the same manner as in Example 1 except that the amount of pentamethylenediamine added in the adjustment example 1 is 12.54kg. Nylon 56 was prepared with a reduced viscosity of 160ml / g.

Abstract

The invention discloses a nylon modified plastic which comprises the following raw materials in parts by weight: (1) 20-80 parts of nylon resin; and (2) one or more of 15-45 parts of reinforcer, 5-20 parts of toughener or 9-15 parts of compound flame retardant, wherein the nylon resin is prepared from pentamethylene diamine and aliphatic dibasic acid used as raw materials, and at least one of the pentamethylene diamine and the aliphatic dibasic acid is prepared through a biological method. The nylon modified particle prepared by the invention has excellent properties of reinforcing, toughening, flame retardance and the like, can be further used in the fields of automobile industry, electronic / electric apparatus industry, mechanical equipment and the like, and has wide industrial application prospects.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular, the invention relates to a nylon modified plastic. Background technique [0002] There are many studies on the modification of conventional nylon resins such as nylon 6 and nylon 66. The modified nylon plastic has high mechanical properties, heat resistance and flame retardancy. obtained a wide range of applications. [0003] The current nylon is basically made of petroleum derivatives as raw materials. For example, the two varieties of nylon 6 and nylon 66 with the largest market share in the nylon market, their raw materials caprolactam and adipic acid are hydrogenated and reoxidized by benzene homologues. Hexamethylenediamine is prepared by first synthesizing adiponitrile from butadiene or acrylonitrile and then by catalytic hydrogenation. The whole synthesis process is complicated and there is some pollution. [0004] For a long time, people have been looking forwar...
