Problems solved by technology

At present, there are three main dyeing methods for thermoplastics: dry dyeing, extrusion dyeing, and dry thick dyeing. These three methods have one thing in common, that is, they all belong to physical blending to achieve the dyeing effect, and there may be uneven dyeing. Uniform condition, and most of the dyes used are organic dyes, which will fade after experiencing harsh working conditions such as high temperature, strong corrosion, and strong radiation

Embodiment 1

[0017] Modified titanium yellow: In a 500ml three-necked flask equipped with magnetic stirring, add 6g titanium yellow, 50ml ethanol aqueous solution, 100ml 20% NaCl aqueous solution, 12ml KH570, drop glacial acetic acid to adjust the pH value to close to 6, and stir in a 90°C water bath 3h, washed with water until neutral, baked in an oven at 60°C to constant weight to obtain modified titanium yellow.

Embodiment 2

[0019] Add 4-5g of AlCl to a 500ml three-necked flask equipped with magnetic stirring and nitrogen conduit 3 , 30ml dichloroethane, 1.25ml N-methylpyrrolidone, lower the temperature to -10 to -15°C, add 2.03g terephthaloyl chloride and 1.6ml diphenyl ether while stirring, and react at this temperature for 1-2 hours, and then warmed up to room temperature for 10-20 hours, adding 50ml of methanol to quench to obtain a white colloid. After crushing, wash with methanol and deionized water in sequence, and finally place the product in an oven and dry it to constant weight to obtain polyether ketone ketone powder.

Embodiment 3

[0021] Add 1.2g of modified titanium yellow with a particle size of 300nm and 4-5g of AlCl 3 , 30ml dichloroethane, 1.25ml N-methylpyrrolidone, lower the temperature to -10 to -15°C, add 2.03g terephthaloyl chloride and 1.6ml diphenyl ether while stirring, and react at this temperature for 1-2 hours, and then warmed up to room temperature for 10-20 hours, adding 50ml of methanol to quench to obtain a yellow colloid. After crushing, wash with methanol and deionized water in sequence, and finally place the product in an oven and dry it to constant weight to obtain yellow polyether ketone ketone powder.

[0022] Example 3

[0023] Add 1.2g of modified titanium yellow with a particle size of 3um and 4-5g of AlCl 3 , 30ml dichloroethane, 1.25ml N-methylpyrrolidone, lower the temperature to -10 to -15°C, add 2.03g terephthaloyl chloride and 1.6ml diphenyl ether while stirring, and react at this temperature for 1-2 hours, and then warmed up to room temperature for 10-20 hours, add...

Abstract

The invention discloses a yellow polyether ketone ketone (PEKK) powder preparation method, which comprises the following steps: (a) chemically modifying the surfaces of inorganic yellow particles by using a coupling agent; (b) adding a certain proportion of the modified inorganic yellow particles in a polyether ketone ketone synthesis process, so that the modified inorganic yellow particles are inchemical bond linkage with the polyether ketone ketone; (c) smashing the yellow polyether ketone ketone composite resin obtained by the reaction, and repeatedly cleaning with ethanol and deionized water; and (d) putting the cleaned yellow polyether ketone ketone composite resin powder into a drying oven, and drying to achieve a constant weight so as to obtain the yellow polyether ketone ketone powder. According to the technical scheme, the dyeing effect is achieved through chemical synthesis instead of physical blending, the yellow polyether ketone ketone powder with the uniform color can beobtained, and the used dye is an inorganic matter, can resist high temperature, corrosion and radiation, cannot fade, and has great advantages in the aspects of use value and environmental protection.

Description

technical field [0001] The invention relates to a preparation method of a polyether ketone ketone inorganic composite material, in particular to a preparation method of an inorganic yellow dye and polyether ketone ketone composite material. Background technique [0002] Polyether ketone ketone is one of the special engineering plastics, which has excellent mechanical properties, solvent resistance, chemical corrosion resistance, good flame retardancy and radiation resistance, etc. At present, it is widely used in the fields of national defense and military industry, aerospace, electronic information, automobile manufacturing, petrochemical industry, medical and health care, household appliances, and automobile manufacturing. It is mainly used as a material for special working conditions such as high temperature, strong corrosion, and strong radiation. [0003] Most thermoplastic raw materials are transparent, brown or off-white, and some products used in special working cond...
