Abstract

The invention relates to a method and a device for infiltrating a reinforced material and resin glue continuously, wherein an infiltrating tank is firstly prepared; the infiltrating tank is provided with at least two or more than two sizing grooves arranged in an array manner; the viscosity of the resin glue filled in all sizing grooves increases orderly; the reinforced material is sprayed with the resin glue by a high-pressure glue-spraying gun in advance, and then enters each sizing groove to be infiltrated in sequence; and when entering each sizing groove, the sequence of the reinforced material is from the sizing groove with the low resin viscosity to the sizing groove with the high resin viscosity. Due to the adoption of entering and exiting the sizing groove for multiple times, the method and the device can prolong the infiltrating time of the reinforced material and the resin glue so as to solve the problem of the insufficient infiltration of the reinforced material; and the reinforced material also can be sprayed with the resin glue by the high-pressure glue-spraying gun in advance and enters the sizing grooves with different viscosity to be infiltrated so as to lead bubbles remained on the reinforced material to be effectively replaced, thus leading the reinforced material to achieve good infiltrative property. The invention has simple structure and convenient operation, and is beneficial to the industrial application.

Description

technical field

[0001] The present invention relates to the production method and equipment technology field of prepreg used in copper-clad laminates, in particular to a method and device for continuously infiltrating reinforcing materials and resin glue to achieve good wettability. Background technique

[0002] As we all know, in the circuit board manufacturing industry, copper clad laminates become the basic material for circuit board processing, and the quality of copper clad laminates will also directly affect the performance of circuit boards, which means that the processing of prepregs (adhesive sheets) in the field of copper clad laminates is particularly important ; The prepreg is obtained by soaking the semi-finished reinforcing material (glass fiber cloth, fiber paper, etc.) in epoxy resin glue and heating and drying the soaked reinforcing material.

[0003] In the prior art, there are many ways to infiltrate the reinforcing material with the resin glue. For exampl...
