Problems solved by technology

[0002] With the progress of society, the use of automobiles is increasing. Many connectors and connectors on automobiles are made of nylon. The existing plastic connectors are mainly made of ordinary nylon materials, which are compounded by adding toughening agents. After mixing various materials, the dispersibility of each component is poor during the blending process, the compatibility between each component is poor, the strength, toughness, and corrosion resistance are insufficient, the material cost is high, the demoulding is difficult, the surface gloss is poor, and the processing Poor performance leads to unstable product quality, low product qualification rate, and reduces economic efficiency, thus affecting the performance of the car

Embodiment 1

[0031] Prepare polytetrafluoroethylene modified nylon PA66 particle material, the specific steps are:

[0032] The first step: prepare material A (kg):

[0033] Weigh nylon PA6650, ASA resin 15, polytetrafluoroethylene 15, 3-aminopropyltrimethoxysilane 0.2, methyltriethoxysilane 0.4, antioxidant 10100.2, anti-ultraviolet agent 0.3, polycaprolactone 2. Polyethylene wax 1.5, modified nano powder 8,

[0034] Among them, the modified nano powder is prepared by the following method: after mixing calcium carbonate, lapis lazuli powder, and potassium feldspar powder in equal proportions, burning at 600-700°C for 4-5 hours, then grinding into nano powder, mixing into Stir evenly with 3-5% bis(dioctyloxypyrophosphate) ethylene titanate by weight of the powder, dry and pulverize into powder,

[0035] Mix the weighed raw materials evenly, inhale into a drying barrel, and dry at 75-90°C for 4-6 hours;

[0036] When the water content of the mixture is less than 3%, the drying ends;

[...

Embodiment 2

[0046] With the polytetrafluoroethylene modified nylon PA66 particle material that embodiment 1 makes, prepare the connector blade type plug sheath DJ7135-3-11 on the automobile, comprise the following steps:

[0047] (1) After mixing 25kg polytetrafluoroethylene modified nylon PA66 particles and 1.5g yellow-green powder evenly, add it to the dryer and dry it at 100-120°C for 5 hours.

[0048] (2) Set the temperature of the heating section of the injection molding machine: the first section is 285±5°C, the second section is 280±5°C, the third section is 270±5°C, the fourth section is 265±5°C, and the fifth section is 260±5°C ;

[0049] (3) Add the dried raw materials into the injection molding machine, and set the molding process parameters of the injection molding section:

[0050] a. The first section adopts medium and low pressure of 35-40Mpa and medium speed of 45-55m / s for injection, the injection time is 1.0-1.5 seconds, and the amount of glue injected is 78-80% of the ...

Abstract

The present invention discloses a polytetrafluoroethylene modified nylon PA66 particle material, which is obtained by mixing a material A of the polytetrafluoroethylene modified nylon PA66 and a material B of the polytetrafluoroethylene modified nylon PA66, and then carrying out extrusion granulation. The present invention further discloses applications of the obtained modified nylon PA66 particle material in vehicle parts. The preparation method mainly comprise adding the dried modified material to a heated injection molding machine, setting injection pressures, speeds, injection times and glue injection amounts at different segments of the injection molding machine, and setting a final packing pressure and a packing speed to achieve an optimal injection molding process so as to obtain the final qualified product. After the modified nylon PA66 particle material is used for plastic connection devices of vehicles in the injection molding manner, advantages of high surface finish, good toughness, high strength and the like are provided, demolding is easily performed during injection molding, product quality is stable, a qualification rate is high, production efficiency is improved and production cost is reduced.
