Abstract

The invention discloses a glass fiber reinforced polyamide / polyester alloy and a preparation method thereof. The glass fiber reinforced polyamide / polyester alloy consists of the following components in percentage by weight: (A) 99-30 percent of resin component and (B) 70-1 percent of glass fiber, wherein the resin component (A) consists of the following components in percentage by weight: (1) 97-1 percent of polyamide of which the intrinsic viscosity is 1.8-3.0 dL / g, (2) 97-1 percent of polyester of which the intrinsic viscosity is 0.6-0.9 dL / g, (3) 1-20 percent of compatilizer and (4) 1 percent of other aids. The preparation method comprises the following steps of: weighing the materials with an electronic metering scale; feeding the materials into a dual-screw extruder respectively; and melting and mixing together to obtain a high-strength and high-toughness glass fiber reinforced polyamide / polyester alloy. The method is simple, and the performance of the obtained polyamide / polyester alloy is higher than that of a glass fiber reinforced nylon material.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a high-strength, high-toughness glass fiber reinforced polyamide / polyester alloy and a preparation method thereof. Background technique

[0002] Due to its special molecular structure, polyamide has excellent mechanical properties, self-lubricating properties and thermal stability, and is widely used as engineering plastics in the fields of automobiles, electronic appliances, machinery and sports equipment. However, polyamide has disadvantages such as high molding shrinkage rate and high water absorption rate, which make the dimensional stability of the prepared parts poor, which limits the use of polyamide.

[0003] Glass fiber reinforced polyamide can significantly improve the mechanical properties of polyamide, but the inherent molding shrinkage and high water absorption of polyamide are difficult to be effectively solved by glass fiber filling. The polyamide / polye...
