Abstract

The invention relates to the technical field of reinforcing material modification, in particular to a POM / PET alloy material and a preparation method thereof. The POM / PET alloy material comprises, by weight, 55%-90% of POM; 15%-40% of PET; 5%-20% of a blending agent; 3%-7% of a phase solvent; 0.5%-2% of an antioxidant; 0.3%-1% of a formaldehyde absorbent; 0.1%-0.6% of a chain extender; and 0.1%-0.5% of a coupling agent. The high contractibility of the POM material is reduced and the impact strength of the POM material is improved through the formaldehyde absorbent and the blending agent, so that POM / PET is easily compatible, the performance of the POM / PET alloy modified material is improved, the material advantages of POM / PET are combined, and the POM / PET alloy modified material not only has wear resistance, high rigidity, self-lubricating property and oil resistance, but also has the characteristics of excellent impact resistance, aging resistance and low shrinkage. Therefore, the two materials have wider market and application prospects.

Description

technical field [0001] The invention relates to the technical field of reinforcement material modification, in particular to a POM / PET alloy material and a preparation method thereof. Background technique [0002] In the prior art, the publication number is CN201810962625.4, and the invention patent named as a glass fiber reinforced PBT / PET material uses alloying technology to form a stable multiphase structure by mixing nylon with PBT and PET, which can not only Reduce warpage without reducing the mechanical properties of the material; at the same time, nylon can improve the impact performance of PBT and accelerate the crystallization speed of PET; in addition, the invention also adds a toughening compatibilizer to make PBT and polyamide blend When amide-ester exchange reaction occurs, when epoxidized polymer (such as epoxy resin) is used as compatibilizer, PBT-co-Epoxy-co-PA66 copolymer is formed in the blending process, which can effectively improve The compatibility bet...
