Abstract

The invention discloses a scratch-resistant black heat transfer printing ink and a preparation method thereof. The printing ink comprises the following components in percent by weight: 25-35 percent of epoxy resin, 5-8 percent of phenolic resin, 3.5-5.0 percent of a curing agent, 45-60 percent of a heat conducting filling material, 10-12 percent of a coloring agent and 0.5-0.7 percent of an additive. The printing ink has a rigidity larger than 6 H after being roasted and pressed to meet the scratch-resistant requirement of Al-based copper-clad plate production and manufacturing, has the thermal conductivity reaching 1.5 W to facilitate the radiating of an Al-based copper-clad plate compared with an anodic oxidation film and a PET protecting film, and has a maximum bearing temperature of 230 DEG C and maximum pressure of 100 kg / cm<2>, and therefore, a novel method for using the heat transfer printing ink is found, the radiating function of the Al-based copper-clad plate is not affected while the aluminium surface is prevented from scratching. The heat transfer printing ink is a new measure for protecting the aluminium surface of the Al-based copper-clad plate.

Description

technical field [0001] The invention relates to the technical field of printed circuit board production, in particular to an anti-scratch black heat-conducting ink and a preparation method thereof. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. [0003] The hardness of the aluminum plate without surface treatment is HW12, which is a low-hardness material. During the handling and production process, it is easy to produce surface scratches and scratches; therefore, the production process of aluminum-based copper-clad laminates that have great requirements for the appearance of the aluminum surface , it is necessary to carry out anti-scrat...
