Problems solved by technology

[0002] At present, based on the fire protection requirements for composite panels, most of the inorganic substances are used as decoration and support materials in the market, such as stone, glass, aluminum veneer and A2 flame-retardant composite panels, and the quality of inorganic substances is relatively heavy. When the board is used, it will be limited by the load-bearing capacity of the building, and during the construction process, the installation cost and transportation cost of such materials are relatively high

Embodiment Construction

[0021] In order to better understand the technical solution of the present invention, the following will be described in detail through specific examples:

[0022] A production process of a lightweight A2-grade flame-retardant and heat-insulating composite board of the present invention specifically includes the following steps.

[0023] Step 1. Produce the special lightweight A2-grade flame-retardant and heat-insulating composite board core material through the standard production process, and then load it, and set it above the exit (or divide into two groups, and the core material is released in the form of unwinding). A set of unwinding device is used for unwinding the hot melt adhesive. Before the first section of the baking furnace, the hot melt adhesive is preliminarily pasted on both sides of the core material with a pressure roller, and the pressure of the pressure roller is 3-5kg.

[0024] Step 2, before the first section of the baking furnace, set up a group of mixed...

Abstract

The invention discloses a production process of a light A2-grade flame-retardant heat-insulating composite board. The production process comprises the following steps that step 1, hot melt adhesive is preliminarily and thermally pasted on two surfaces of a core material; step 2, the PE aerogel plastic and a middle light aerogel flame-retardant core material are bonded and shaped; step 3, the second layer of PE aerogel plastic and the middle light aerogel flame-retardant core material are bonded and shaped; step 4, the composite core material is leveled; step 5, the plate surface of the composite core material is heated through infrared rays after cooling; step 6, the metal color-coated roll and the core material are attached through a hot melt adhesive; and step 7, the composite board is trimmed and stacked. According to the production process of the light A2-grade flame-retardant heat-insulating composite board, efficient production of the light A2-grade flame-retardant heat-insulating composite board can be realized.

Description

technical field [0001] The invention relates to a production process of a lightweight A2 grade flame-retardant and heat-insulating composite board used in the field of composite boards. Background technique [0002] At present, based on the fire protection requirements for composite panels, most of the inorganic substances are used as decoration and support materials in the market, such as stone, glass, aluminum veneer and A2 flame-retardant composite panels, and the quality of inorganic substances is relatively heavy. When the board is used, it will be limited by the load-bearing capacity of the building, and during the construction process, the installation cost and transportation cost of such materials are relatively high. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a production process of a lightweight A2-grade flame-retardant and heat-insulating composite board, which can realize ...
