Moisture-proof and anti-aging PC carrier tape material and preparation method thereof

Abstract

The invention relates to the field of packaging materials, and particularly discloses a moisture-proof and anti-aging PC carrier tape material and a preparation method thereof. The moisture-proof and anti-aging PC carrier tape material is prepared from the following raw materials in parts by weight: 100 parts of polycarbonate, 10 to 20 parts of ABS resin, 5 to 10 parts of MBS resin, 10 to 15 parts of modified nano titanium dioxide, 3 to 5 parts of an antistatic agent and 0.1 to 0.3 part of an antioxidant, and the modified nano titanium dioxide is prepared by carrying out self-polymerization surface modification on nano titanium dioxide through dopamine and then reacting the modified nano titanium dioxide with carboxylated cellulose. The PC carrier tape material can be used for packaging electronic components and has the advantages of light aging resistance and moisture aging resistance.

Description

technical field [0001] The application relates to the field of packaging materials, more specifically, it relates to a moisture-proof and anti-aging PC carrier tape and a preparation method thereof. Background technique [0002] Carrier tape refers to a packaging product used in the field of electronic packaging. It is used with cover tape to carry and store electronic components such as resistors, capacitors, transistors, and diodes in the holes (also known as pockets) of the carrier tape. The cover tape is sealed above the carrier tape to form a closed package, which is used to protect electronic components from contamination and damage during transportation. [0003] In order to ensure the performance of electronic components, the electronic carrier tape usually needs to have a certain antistatic property. There are two traditional ways to improve the antistatic performance of the carrier tape. One is to increase the conductivity of the carrier tape by adding conductive ...

AI Technical Summary

Problems solved by technology

There are two traditional ways to improve the antistatic performance of the carrier tape. One is to increase the conductivity of the carrier tape by adding conductive materials such as carbon black, carbon nanotubes, and graphene, thereby reducing the static electricity generated by the carrier tape; The coloring power of the material is relatively strong, which will make the carrier tape appear black, which cannot meet the requirements of light-colored carrier tape

The second is to add a surfactant antistatic agent. When the carrier tape is in a humid environment, the antistatic agent can reduce the surface resistivity of the material by absorbing moisture in the air to achieve antistatic purposes. However, for PC materials, It has the defects of light aging and easy aging in humid environment. In this humid environment, the mechanical properties of the carrier tape will gradually decrease.
