Flame-retardant high-strength automobile interior ABS material and preparation method thereof

Abstract

The invention discloses a flame-retardant high-strength automobile interior ABS material and a preparation method thereof. An antibacterial filler and a modified glass bead filler are added into the ABS material; wherein the modified glass bead filler takes glass beads as a main material; the glass beads have a good heat insulation effect; a titanium dioxide layer is attached to the surface of each glass bead, and a polystyrene layer is formed on the surface of a glass bead intermediate through bonding of titanium dioxide and polystyrene, so that the dispersion effect of the glass beads in ABSresin is improved, and the heat insulation and enhancement performance of the ABS material is improved; in the preparation process of the antibacterial filler; according to the preparation method, montmorillonite is taken as a main material, zinc nitrate is converted into zinc oxide in a porous structure of montmorillonite, the zinc oxide has good broad-spectrum sterilization capability under anillumination condition, and a polystyrene layer is formed on the surface of organic montmorillonite, so that the dispersion effect of the organic montmorillonite in ABS resin is improved, and the heatinsulation and enhancement properties of the ABS material are improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant high-strength automotive interior ABS material and a preparation method thereof.

AI Technical Summary

Problems solved by technology

[0003] Because the ABS material has the characteristics of flammability and high insulation, as an ABS material used in automotive interiors, in order to ensure safety and comfort, the ABS material should have flame retardant, antistatic and other effects, and at the same time should have The higher strength does not prevent the obvious deformation and damage of the ABS material during the preparation process, and because the car interior material is easy to absorb heat when the car is exposed to high temperatures in the sun, the temperature inside the car rises rapidly and even the interior material is heated and deformed. Therefore, it is necessary to process the traditional ABS material to improve or even solve this situation. In order to solve the above problems, a high-strength ABS material for automotive interiors with flame retardancy and heat insulation is provided. The present invention provides the following technical solutions
