Abstract

The invention discloses a polyethersulfone enhanced composite material and a preparation method of the polyethersulfone enhanced composite material. The composite material disclosed by the invention is prepared from the following raw materials in parts by weight: 1.0 to 15.0 parts of basalt fiber, 85.0 to 99.0 parts of polyethersulfone, 1 to 3 parts of a coupling agent and 10 to 25 parts of an activating agent; wherein the basalt fibers contain barium phosphate; the activating agent is one or more of ethylenediamine phosphate, propylene diamine phosphate and sodium fluorosilicate; the composite material has excellent performance and the polyethersulfone composite material is easily popularized and applied in all fields.

Description

technical field [0001] The invention relates to the field of polyethersulfone composite materials, in particular to a polyethersulfone reinforced composite material and a preparation method thereof. Background technique [0002] Polyethersulfone is produced by condensation of 4,4'-bissulfonyl chloride diphenyl ether with diphenyl ether under the catalysis of anhydrous ferric chloride. Polyethersulfone has good comprehensive properties. Polyethersulfone is resistant to high temperature and Good corrosion and impact resistance, good molding dimensional stability, and excellent mechanical properties within the service temperature; but due to the strong activity of the ether group, polyethersulfone has the defects of poor UV resistance, poor water resistance, and high cost , Therefore, the modification of polyethersulfone to reduce cost and maintain performance plays an important role in the application of polyethersulfone. Nowadays, the fiber reinforcement modification of poly...
