Honeycomb aluminum-plastic panel with high surface hardness and its production process

Abstract

The invention discloses a honeycomb aluminum-plastic panel with a high surface hardness and a production process thereof. It relates to a panel and aims to solve the problem of low hot pressing efficiency. Aluminum plate and PVC composite panel, the honeycomb aluminum plate includes an aluminum bottom plate and a honeycomb aluminum mesh arranged on the surface of the aluminum bottom plate, a composite glue layer is arranged between the aluminum bottom plate and the honeycomb aluminum mesh, the PVC composite panel and the honeycomb A composite adhesive layer is arranged between the aluminum meshes, and the composite adhesive layer is a mixture of a PUR hot-melt adhesive film and a two-component polyurethane high-temperature curing adhesive. The high-hardness honeycomb aluminum-plastic panel of the present invention adopts a single-sided PVC composite panel, which reduces production costs on the one hand, and ensures heat transfer efficiency during hot-pressing and compounding on the other hand. Thereby improving production efficiency.

Description

technical field [0001] The invention relates to board materials, more specifically, it relates to a honeycomb aluminum-plastic board with high surface hardness and its production process. Background technique [0002] Honeycomb aluminum-plastic panel is a new type of panel combining honeycomb aluminum panel and aluminum-plastic panel. [0003] Notification number is CN106626549B a kind of anti-ultraviolet honeycomb composite panel of Chinese patent announcement, and its technical essentials are: comprise honeycomb panel core material, honeycomb panel panel, honeycomb panel panel base film; The core material of the honeycomb board is composited together; the honeycomb board panel is composed of the following components by weight: 40-100 parts of thermoplastic material, 0.5-1.5 parts of coupling agent, 0.5-2 parts of dispersant, and 0.1-5 parts of ultraviolet absorber parts, 0.1-5 parts of free radical scavenger; the base film of the honeycomb panel panel is composed of the f...

Problems solved by technology

[0004] In the above technical solution, it is disclosed in claim 9 that "the honeycomb panel core material is preheated and pressed, the hot pressing temperature is 200°C, the pressure is 0.4Kpa, and the hot pressing time is 20s, so that the bottom film of the honeycomb panel panel and the surface layer of the honeycomb panel core material Preliminary fusion; take out the preheated product, lay a honeycomb panel on the upper and lower sides, and perform hot pressing again. The hot pressing temperature is 200°C, the pressure is 0.4Kpa, and the hot pressing time is 50s; Cold pressing and fixed molding; the cold pressing pressure is 0.4Kpa, and the cold pressing time is 75s to form a firm honeycomb composite panel". It can be seen that the scheme is to use the bottom film of the hot-melt honeycomb panel panel and the surface layer of the honeycomb panel core material to achieve The connection between the honeycomb composite panel and the honeycomb panel panel, but this method needs to be hot-pressed on the honeycomb panel, and the heat needs to pass through the honeycomb panel with poor thermal conductivity to melt the bottom film of the honeycomb panel panel. low, so a new solution is needed to solve this problem
