[0026] [Amorphous polyamide resin composition]

[0027] The amorphous polyamide resin composition of the present invention contains a resin component containing an amorphous polyamide resin and a glass filler.

[0028] In addition, in the amorphous polyamide resin composition of the present invention, it is preferable that the difference between the refractive index of the resin component comprising the amorphous polyamide resin and the refractive index of the glass filler is 0.002 or less for light having a wavelength of 589 nm. For light with a wavelength of 486 nm, it is 0.002 or less, and for light with a wavelength of 656 nm, it is 0.002 or less. More preferably, the difference in refractive index for the light of the above three kinds of wavelengths is 0.001 or less. If the difference in refractive index between the resin component containing the amorphous polyamide resin and the glass filler is greater than 0.002 for each of the above three wavelengths of light, the tr...

Abstract

The invention provides a non-crystalline polyamide resin composition with enough transparency and excellent rigidity, mechanical performance, physical performance and heat resistance, and a product thereof. The composition adopts glass filler which is represented by the mass percentage based on oxide, contains 68-72 percent of silicon dioxide (SiO2), 2-5 percent of aluminum oxide (Al2O3), 2-5 percent of boron oxide (B2O3), 2-10 percent of calcium oxide (CaO), 0-5 percent of zinc oxide (ZnO), 0-5 percent of strontium oxide (SrO), 0-1 percent of barium oxide (BaO), 1-5 percent of magnesium oxide (MgO), 0-5 percent of lithium oxide (Li2O), 5-12 percent of sodium oxide (Na2O) and 0-10 percent of potassium oxide (K2O), wherein the total amount of lithium oxide, sodium oxide and potassium oxideis 8-12 percent.

Description

technical field [0001] The present invention relates to an amorphous polyamide resin composition and a molded article excellent in transparency, heat resistance and rigidity. Background technique [0002] Conventionally, transparent resins have been used as materials for moldings that generally require transparency, such as automotive parts, lighting equipment, and electrical parts. Especially recently, the application as an optical material emphasizing optical properties is progressing. Among them, non-crystalline polyamide resins are used as transparent resins for optical materials and the like because they have low birefringence and high transparency due to the polymerized monomer structure. [0003] However, non-crystalline polyamide resins have insufficient rigidity. Therefore, attempts have been made to improve the rigidity of amorphous polyamide resin molded articles by adding fiber reinforcing materials such as glass fibers, inorganic fillers, rubber components, an...
