Problems solved by technology

No matter how high the degree of automation of the above process is, it still has a technical problem that is difficult to solve, that is, the product specifications produced are limited: (1) when the height (thickness) of the honeycomb paper core is above 100mm, there will be a pull Not open or unstable, the density is difficult to control
(2) When the paper weight of the paper core produced in general is above 80-180g / m2, it is difficult to stretch and shape the paper core when the height of the paper core is above 50mm
The production efficiency of this process is relatively high, and the plastic honeycomb honeycomb unit produced has good connection strength, but the specifications and materials of the honeycomb aperture and wall thickness are limited by equipment and molds, and are not universal, so a large investment in equipment and molds is required To produce products with corresponding specifications

Embodiment 1

[0017] Embodiment 1: The making of paper honeycomb material.

[0018] As shown in Figure 1, the paper tubes 1 arranged in the same direction are bonded together by the adhesive 2 to form a honeycomb composite. The length of the paper tube can be relatively long, and the thickness of the honeycomb core can be obtained by longitudinally cutting the honeycomb composite Size, edge cut flush. Honeycomb materials of the same size can be spliced ​​to form a honeycomb body of a larger size.

[0019] According to the method of the present invention, the adhesive adopts the impregnated glue whose weight ratio of starch and water is 1:3-8. The drying and curing strength is 30-80°C, and natural sunlight can be used in summer.

Embodiment 2

[0020] Embodiment 2: The making of metal honeycomb material.

[0021] As shown in Figure 1, metal aluminum pipes 1 arranged in the same direction are bonded together by adhesive 2 to form a honeycomb composite. The thickness of the honeycomb material is obtained by cutting the honeycomb composite longitudinally to obtain the required size, and the edges are cut flush. When using metal aluminum tubes to make honeycomb materials, the surface of the aluminum tubes should be pretreated to remove dirt, grease and other anti-sticking substances. According to the method of the present invention, the adhesive adopts a single-component epoxy resin glue solution.

Embodiment 3

[0023] As shown in Figure 1, PVC pipes 1 arranged in the same direction are bonded together by adhesive 2 to form a honeycomb composite. The thickness of the honeycomb material is obtained by cutting the honeycomb composite longitudinally to obtain the required size, and the edges are cut flush. According to the method of the present invention, the adhesive used is composed of methyl ethyl ketone and PVC resin material, methyl ethyl ketone: PVC resin material=80:20 (weight ratio).

Abstract

This invention relates to a compound method to process beehive materials with tubes, which comprises the following steps: distributing the tubes to one direction into model box of frame or net shape; dipping the box with glue liquid; then taking out model box and dripping the over glue liquid; then pressing and drying the tubes with certain pressure; solidifying it into beehive parts and taking out beehive from the box.

Description

technical field [0001] The invention relates to a method for compounding honeycomb materials. Background technique [0002] The honeycomb structure is a masterpiece in the process of biological evolution in nature. It has the best material weight-to-space ratio, the best mechanical structure, specific strength, and specific stiffness. It has good sound insulation and heat insulation performance. It is widely used in aerospace, vehicles, and building materials. Partition walls, doors, furniture, packaging, etc. [0003] Representative honeycomb products are: [0004] Paper honeycomb is a core material made of paper materials, and then the required covering materials are compounded on both sides of the core material, such as color steel plate, gypsum board, plastic board, etc. The traditional paper honeycomb is to glue the paper longitudinally according to a certain pore size and compound it layer by layer, and then use a paper cutter to cut the honeycomb core strip of the r...
