Title:
ANTI-ABRASION POLYESTER RESIN AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/142398
Kind Code:
A1
Abstract:
The present invention relates to an anti-abrasion polyester resin and a preparation method therefor. The preparation method comprises: synthesizing a polyester polymer by using a melt two-step method, the raw materials being neopentyl glycol, ethylene glycol, diphenylsilanediol, trimethylolpropane and terephthalic acid; 2,5-furandicarboxylic acid, isophthalic acid, 2,6-pyridinedicarboxylic acid, trimellitic anhydride, a catalyst, a vulcanization accelerator, ferric chloride, and basalt fibers; coating the polyester polymer in a molten state onto a basalt fiber unidirectional cloth to prepare a basalt long fiber reinforced polyester coating, subjecting same to heat treatment, cutting same after cooling, and grinding same to obtain fiber reinforced polyester powder particles, i.e. the anti-abrasion polyester resin. Fe3+ coordination between 2,6-pyridinedicarboxylic acid segments of different polyester segments in the anti-abrasion polyester resin improves the strength and abrasion resistance of the polyester powder. A coating is prepared from the anti-abrasion polyester resin, and is subjected to an abrasion resistant test and a salt spray resistant test. The abrasion resistance is measured to be 1.87 to 2.13 L/μm, and the results of the salt spray test are: no cracking, no foaming, no whitening, and no peeling for 1000 hours.
