Embodiment 1

[0014] Example 1: 1) Use a laminating machine to evenly coat a layer of styrene butadiene latex on the aluminum foil, dry it in an oven at 77°C until it is sticky, and then combine it with a non-flammable glass fiber mesh composite felt at a temperature of 240°C and a pressure of 0.5Mpa The composite panel is laminated under the heating and pressure roller, and then dried in an oven at 170 ℃ to form an aluminum foil composite panel, and finally the product is wound up. 2) Place the composite aluminum foil composite panel on any surface or upper and lower surfaces of the continuous phenolic foam board production device, and adjust the production device to the height of the 20mm thick board, and then use the expandable phenolic resin composite material with high pressure The foaming machine sprays on the surface of the non-combustible glass fiber mesh composite felt in the composite panel according to certain rules, and then coats the surface of the non-combustible glass fiber mes...

Embodiment 2

[0015] Example 2: 1) Use a laminating machine to evenly coat the color steel plate with a layer of styrene-butadiene latex, dry it in an oven at 72°C until it is sticky, and then heat it with a non-flammable glass fiber mat at a temperature of 280°C and a pressure of 0.62Mpa Laminate under the pressure roller, and then dry in a 180℃ oven to form a color steel composite panel, and finally the product is wound up. 2) Place the composite color steel plate composite panel on any surface or upper and lower surfaces of the continuous phenolic foam board production device, and adjust the production device to the height of the production of 50mm thick boards, and then apply high pressure to the expandable phenolic resin composite material The foaming machine sprays on the surface of the non-combustible glass fiber mat in the composite panel according to certain rules, and then coats the surface of the non-combustible glass fiber mat in the composite panel with a layer of phenolic resin ...

Embodiment 3

[0016] Example 3: 1) Use a laminating machine to evenly coat the aluminum plate with a layer of acrylate glue, then dry it in an oven at 80°C until it is sticky, and then heat it with a non-flammable non-woven fabric at a temperature of 300°C and a pressure of 0.7Mpa. Laminate under the pressure roller, and then dry in a 220 ℃ oven to form an aluminum composite panel. Finally, the product is cut into a certain size aluminum composite panel as required. 2) Place the composite aluminum plate composite panel on any surface or upper and lower surfaces of the shaped mold cavity, and then spray the expandable phenolic resin composition directly on the surface of the non-combustible non-woven fabric in the composite panel at 80°C Heat for 15min to foam and set, then mature and demould at 70℃ to get the product.

Abstract

The invention provides a method to improve the bonding strength of phenolic foam plates, and relates to a phenolic foam plate, in particular to a method to improve the bonding strength of phenolic foam plates during the continuous or intermittent preparation process of phenolic foam plates. A compounding machine is used to coat a composite glue layer on a panel evenly, and the composite glue layer is dried by heat to the extent that the glue layer feels sticky before the panel is compounded with an incombustible fibre glass ware under a heating and pressure roller. In this way, a composite panel is formed after the composite panel is dried. The composite panel is arranged on any surface or both the upper surface and the lower surface of a continuous phenolic foam plate production device or a forming die cavity. Subsequently, foamable phenolic resin combined material is directly sprayed on the surface of the incombustible fibre glass ware inside the composite panel; the composite panelis heated, foamed, set and cured before stripping. In this way, a product is got.

Description

Technical field [0001] The invention relates to a phenolic foam composite board, in particular to a method for improving the bonding strength of the phenolic foam composite board during the preparation process of the continuous or intermittent phenolic foam composite board. Background technique [0002] The bonding ability between the existing phenolic foam and phenolic foam surface board composite is not strong, that is, the bonding is not strong, and it is easy to separate and peel off when the finished product is subjected to secondary processing, and some boards cannot be continuous. Production, such as color steel plate, etc. [0003] The Chinese invention patent application with publication number CN1517194 provides a continuous manufacturing method for phenolic foam composite panels. The casting material is a high-ortho phenolic modified resin that can be continuously foamed at room temperature as the base material, and a curing agent is added. , Foaming agents, buffering a...
