Problems solved by technology

Polyether ether ketone material has superior mechanical properties, which are characterized by high strength, high elastic modulus and elongation at break, excellent dimensional stability, small shrinkage in injection molding, hydrolysis resistance, corrosion resistance, and good flame retardancy However, when pure PEEK resin is used in some harsh working environments such as high temperature and high pressure, it is easy to age and break, and the toughness and strength decrease, which cannot meet the requirements of strong and tough materials.

preparation example Construction

[0055] The embodiment of the present invention also provides a preparation method of the high-toughness blend described in the foregoing technical solution, comprising the following steps:

[0056] a) blending the dispersant and the filler according to the weight ratio of (1.0-10.0): 1 to obtain an initial blend;

[0057] b) Add the initial blend and matrix polymer material to a grinding device, grind at a grinding rate of 1000-1500rpm / min for 15-25 minutes, put the dispersed product in an oven at 140-170°C for 1 - 4 hours to obtain an intermediate blend;

[0058] c) Put the intermediate blend and the thermoplastic polymer material into a high-speed mixer, and stir at a stirring rate of 1000-1500 rpm / min for 20-30 minutes to obtain a high-toughness blend.

[0059] In the embodiment of the present invention, the amount of dispersant can be determined according to the amount of filler and\or matrix polymer material, specifically, make the weight ratio of dispersant to filler be...

[0072] 500g diphenyl sulfone is packed in the three-necked reaction flask, this three-necked reaction flask is equipped with mechanical stirrer, thermometer and nitrogen inlet and outlet, starts stirring device, and stirring rate is 70 revolutions per minute and feeds flow rate at room temperature and is per minute 70ml of high-purity nitrogen. Then the reactant was heated to 130°C at a heating rate of 2°C / min to dissolve it, and then 69.82g of 4,4'-difluorobenzophenone was added, and 35.23g of chicken sodium phenol was dissolved. Add 33.92 g of sodium carbonate immediately after heating at a heating rate of 170°C. The reaction temperature was still raised to 200°C at a heating rate of 2°C / min. Hold this temperature for 20 minutes, continue to ramp up to 280°C at a ramp rate of 2°C / min, and maintain the temperature at 280°C until the desired torque rise is achieved. The molten material was poured into cold distilled water to give a lumpy solid. Grind the block into powder w...

In a specific embodiment, the high-toughness blend comprises a matrix polymer material, a thermoplastic polymer material and a filler, wherein the weight ratio of the matrix polymer material to the thermoplastic polymer material is 3.0-8.0, and the weight ratio of the filler to the matrix polymer material is 1.0: (4.0-20.0); the thermoplastic polymer material has an unnotched impact strength of at least 200 kJm <-2 > and a glass transition temperature of at least 200 DEG C. The high-toughness blend provided by the embodiment of the invention maintains rigidity and strength, also improves toughness, and realizes integration of toughness and toughness.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a high-toughness blend, a preparation method thereof and a plate. Background technique [0002] In recent years, the application of synthetic polymer materials has become more and more extensive, and has completely replaced traditional materials such as metals and ceramics in many fields. Stability, electrical insulation, and chemical resistance are favored by many industries and fields such as aerospace, electronics, automobile traffic, petrochemicals, etc. Polyetheretherketone (PEEK) is the most typical representative of polyaryletherketones and one of the most widely used special engineering plastics. Polyether ether ketone material has superior mechanical properties, which are characterized by high strength, high elastic modulus and elongation at break, excellent dimensional stability, small shrinkage in injection molding, hydrolysis resistance, corrosion resistance, and goo...
