Abstract
The application belongs to the field of materials and particularly relates to an impregnation formula for punched Nomex paper honeycomb and a use method thereof. A defoamer or a surface additive is added to impregnation glue liquid to reduce surface tension of the glue liquid, so that when a honeycomb core plate is moved out from a glue trough, the holes on walls of the honeycomb lattices are unobstructed. The impregnation formula not only improves impregnation quality of punched honeycomb but also increases efficiency of impregnation of the punched honeycomb.
Description
Technical field
The application belongs to Material Field, is specifically related to a kind of impregnation formulation for the Nomex paper honeycomb that punches and using method thereof.
Technical background
Nomex paper honeycomb core material is the key components of sandwich radome. Honeycomb sandwich construction radome specific use is needed, guarantee to be molded between comb core checkerwork cell and the checkerwork cell within cover body and there is the passage that gas flows, therefore need to manufacture the honeycomb core plate that there is hole on honeycomb lattice septum, owing to punching diameter is little, tradition glue dipping punching honeycomb is adopted to be very easy to cause plug-hole phenomenon, cause comb core checkerwork cell and checkerwork cell gas to circulate, lose the purposes of punching honeycomb.
Employ hair dryer during tradition glue dipping punching honeycomb and blow down honeycomb lattice septum hole glue plug-hole phenomenon, but owing to hair dryer is in the process blowing down hole glue, more easily cause the dry rapidly of impregnated resin liquid, therefore the dry film that on lattice septum hole, glue is formed is more difficult to blow down, and has a strong impact on the quality of punching honeycomb.
For these reasons, a kind of impregnation formulation that can be used in punching Nomex paper honeycomb of invention design just seems particularly necessary.
Summary of the invention
In order to solve the plug-hole problem of honeycomb lattice septum hole in punching honeycomb dipping process, the application adds a kind of defoamer or surface modifier at dipping glue, reduce glue surface tension, therefore when honeycomb core plate removes from glue groove, hole on honeycomb lattice septum is just for unobstructed, therefore not only increase the impregnating effect of punching honeycomb, also improve the efficiency of dipping punching honeycomb.
To achieve these goals, the technical scheme that the application takes is as follows:
A kind of impregnation formulation for the Nomex paper honeycomb that punches, impregnates at honeycomb and adds defoamer or surface modifier in glue phenolic aldehyde spirit varnish, and described defoamer or surface modifier account for the 0.05%～1% of formula gross mass;
Wherein defoamer does not have froth breaking effect very little, and defoamer affects honeycomb dipping effect too much, thus affecting honeycomb performance.
Described surface modifier is selected from BYT-306N organosilyl surface auxiliary agent.
Described defoamer is selected from BYT-066N organic silicon defoamer, BYT-141N organic silicon defoamer, any one in AIR-10 silicon polyether antifoam agent;
Preferably, defoamer is selected from BYT-066N organic silicon defoamer;
The using method of a kind of impregnation formulation for the Nomex paper honeycomb that punches, specifically comprises the following steps that
(1) at room temperature, the defoamer or the surface modifier that weigh formula ratio join in honeycomb dipping glue phenolic aldehyde spirit varnish, and stirring and dissolving is standby;
(2) after Nomex paper honeycomb central layer cutting, between the core bar glue being perpendicular to stack direction, each blank space gets through hole, punching diameter can be 0.8mm～1.5mm, 1min～5min in glue prepared by step (1) at room temperature it is impregnated into after being stretched, then extract honeycomb to carry out upset and hang, hang after the laggard baking oven of 4h～8h carries out preliminary drying and use.
Dipping glue adds defoamer or surface modifier, it is possible to resolve the plug-hole problem of lattice septum hole after punching honeycomb dipping.
The punching Nomex paper honeycomb of the impregnated resin immersion stain of present invention preparation, can be used for honeycomb sandwich construction advanced capabilities radar cover manufacture, needs to be discharged by gas in honeycomb checkerwork cell or enter, it is achieved its peculiar function in this radome manufacture process.
