Problems solved by technology

In addition, sulfone polymers are sensitive to additives. When there are too many types of additives or the amount of additives is too large, the product is prone to deformation, twisting, and pressure cracking, which will reduce the service life of the product.

Embodiment 1

[0053] Add 5.586kg (30mol) of 4,4'-dihydroxybiphenyl, 8.787kg (30.6mol) of 4,4' -Dichlorodiphenyl sulfone, then add 32.62kg of sulfolane, stir and heat up to 100°C to dissolve the monomer until the solution is transparent, add 3.396kg (32.039mol) salt-forming agent Na 2 CO 3 And 132.6g (0.961mol) salt-forming agent K 2 CO 3 , then add 2L of xylene, continue to stir and heat up until the salt-forming reaction begins, the azeotrope generated by the water and xylene in the system is blown out by the protective gas, condensed and dropped to the water separator for stratification, and the upper layer The xylene was refluxed into the system again; the temperature was maintained in the range of 200°C to 210°C, and when the amount of collected water was close to the theoretical value (540g), the reflux was continued for another 20 minutes, and no water drops were observed, which proved that the salt formation was complete, and then Distill and release xylene, and gradually raise th...

Embodiment 2

[0055] The preparation process conditions are the same as in Example 1 to prepare polyphenylene sulfone PPSU, add the additives PEPQ and 1330 to the PPSU resin powder in a weight ratio of 1:1, mix with a high-speed mixer for 10 minutes to ensure uniform mixing, and then extrude with a single screw Melt granulation by machine to obtain plastic particles of sulfone polymer composition, wherein the total content of additives is 3000ppm by weight in the sulfone polymer composition. Then use an injection molding machine to melt and prepare a color plate. The crystal point, air bubbles and yellowing performance index tests were carried out with the prepared transparent swatches, and the results are shown in Tables 4-6.

Embodiment 3

[0057] The preparation process conditions are the same as in Example 1 to prepare polyphenylene sulfone PPSU, add the additives PEPQ and 1010 to the PPSU resin powder in a weight ratio of 99:1, mix with a high-speed mixer for 10 minutes to ensure uniform mixing, and then extrude with a single screw Melt granulation with a machine to obtain plastic particles of the sulfone polymer composition, wherein the total content of additives is 500 ppm by weight in the sulfone polymer composition. Then use an injection molding machine to melt and prepare a color plate. The crystal point, air bubbles and yellowing performance index tests were carried out with the prepared transparent swatches, and the results are shown in Tables 4-6.

Abstract

The invention discloses a sulfone polymer composition and application thereof. The sulfone polymer composition comprises one of polysulfone, polyether sulfone and polyphenylene sulfone, phosphite additive and hindered phenol additive, heat resistance of the phosphite additive and the hindered phenol additive is characterized by heat weightlessness analysis (TGA), weightlessness at 360 DEG C is not higher than 10%, and the hindered phenol additive accounts for 1-50% of total sum of the phosphite additive and the hindered phenol additive. The sulfone polymer composition can be applied in the field of food safety, household electrical appliances, medical health, electronics, aerospace or energy chemical industry.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a sulfone polymer composition and a thermoplastic molding composition composed of it and its application. Background technique [0002] Sulfone polymers are special high-temperature-resistant transparent thermoplastic engineering plastics, mainly including three types: polysulfone PSU, polyethersulfone PES and polyphenylene sulfone PPSU.
