Problems solved by technology

However, in the actual production process, the production efficiency of such hot wire cutting is low, the cutting resistance of the heating wire is large and easy to relax, and the installation and cooling of the metal sheet also lead to complex structure and poor reliability.

Embodiment 1

[0027] A method for preparing a thermoplastic honeycomb plate, comprising the steps of:

[0028] 1) manufacturing a double-layer composite pipe, the inner layer of the double-layer composite pipe is a high melting point material layer, the outer layer of the double layer composite pipe is a low melting point material layer, and the melting point of the low melting point material layer is lower than the melting point of the high melting point material layer;

[0029] 2) A plurality of double-layer composite pipes are arranged in an orderly bundle, and the outer layer of the double-layer composite pipe is melted by heating while the inner layer is not melted. After cooling, the outer layers of the adjacent double-layer composite pipes are bonded together to form honeycomb body;

[0030] 3) The honeycomb body is cut along the cross-section of the double-layer composite pipe by a hot wire cutting machine, thereby obtaining a plate-shaped honeycomb substrate; wherein, such as figu...

Abstract

The invention discloses a thermoplastic cellular sheet material and a preparation method thereof. The preparation method comprises the following steps of 1, manufacturing double-layer clad pipes, 2, carrying out ordered arrangement bundling on the double-layer clad pipes, carrying out heating so that the outer layers of the double-layer clad pipes are melt and the inner layers are non-fusible, and carrying out cooling so that the adjacent and clingy outer layers of the double-layer clad pipes are bonded to form a cellular body, 3, cutting the cellular body along cross sections of the double-layer clad pipes to obtain tabular cellular bases, wherein in hot-wire cutting, the bottom of the cellular body is built on stilts and the upper part of the cellular body is pumped down by an exhaust cowl so that air vertically flowing through the pipe holes of the cellular body accelerates heat dissipation cooling, upper and lower plate bonding after hot-wire cutting is avoided and production efficiency is improved, and 4, compounding surface layer materials on the top surface and the bottom surface of the cellular base by hot pressing. The thermoplastic cellular sheet material improves hot-wire cutting production efficiency and product quality.
