Abstract
The invention relates to the technical field of lighters, in particular to a modified PA material for plastic lighter shells and a preparation method thereof. The modified PA material includes the following components by weight: 60-70 parts of PA66, 30-40 parts of glass fiber, 10-12 parts of polyvinyl alcohol, 5-8 parts of silane coupling agent, 3-5 parts of chlorinated paraffin 1-3 parts of dibutyltin dilaurate, 10-15 parts of white carbon black, 2-5 parts of stearylamide, with excellent anti-fragmentation and splash performance. The modified PA material of the present invention is prepared through the processes of heating and drying, material mixing and extrusion granulation, and has the characteristics of simple process and convenient operation, and is convenient for batch production.
Description
technical field [0001] The invention relates to the technical field of lighters, in particular to a modified PA material for a shell of a plastic lighter and a preparation method thereof. Background technique [0002] Plastic lighters are a simple way of making fires that are commonly used today. At present, the shell of plastic lighters uses styrene-acrylonitrile copolymer (SAN). However, although the styrene-acrylonitrile copolymer is hard and transparent, its impact resistance is poor and it is easy to break. Under some high temperature conditions, such as close to an open flame, the plastic lighter made of styrene-acrylonitrile copolymer is easy to burst, which brings safety hazards to people's daily life. [0003] To this end, the Chinese invention patent application publication number CN109676854A discloses a plastic lighter casing, the casing includes a mixed material of styrene-acrylonitrile copolymer and basalt fiber, and the mixed material is injected into the cas...
