preparation example Construction

[0068] The present invention also provides a method for preparing the fireproof and heat insulating board described in the above technical solution, comprising the following steps:

[0069] a) covering the resin film on the reinforcement layer to obtain a reinforcement layer pasted with the resin film; the resin in the resin film is a flame retardant resin;

[0070] b) Covering the reinforced layer with the resin film attached to the airgel core material layer obtained in step a) on the upper and lower sides of the airgel core material layer, and then sealing the edges with resin at the edge of the airgel core material layer to obtain a prefabricated part;

[0071] c) performing hot-pressing treatment on the prefabricated part obtained in step b), and obtaining a fire-proof and heat-insulating board after cooling.

[0072] In the present invention, the resin film is firstly covered on the reinforcing layer to obtain the reinforcing layer pasted with the resin film. In the pre...

[0095] The structural schematic diagram (exploded view) of the fire-proof and heat-insulating panel provided by Embodiment 1 of the present invention can be found in image 3 shown.

[0096] Concrete preparation process is as follows:

[0097] (1) Add 200g / m 2 resin film (see Figure 4 As shown) covered on the glass fiber cloth, the glass fiber cloth located on the lower surface of the airgel core material is covered with 2 layers of resin film (the final 2 layers of resin film are both between the core material and the reinforcement layer), and the resin film is cut 30mm wide, paste it on the edge of the glass fiber cloth to enhance the bonding strength of the edge, cut the resin film into a square with a side length of 80mm, and paste it on the center of the glass fiber cloth, see Figure 5 As shown; the upper and lower sides of the glass fiber cloth on the upper surface of the airgel core material are covered with a layer of resin film (the final layer of resin film is b...

Abstract

The invention provides a fireproof thermal insulation board. The fireproof thermal insulation board comprises an aerogel core material layer; reinforcing layers which are compounded on the upper surface and the lower surface of the aerogel core material layer; a resin edge sealing layer which covers the edge of the aerogel core material layer; and a reinforcing layer which is compounded with the aerogel core material layer through flame-retardant resin. Compared with the prior art, the fireproof heat insulation plate provided by the invention takes aerogel as a core material, adopts a specific layer structure, and realizes better overall interaction under a specific connection relationship; a compact, firm and tough composite material skin is formed on the surface of the product, the product is endowed with stronger heat insulation and sound insulation effects while the strength is improved, and a complex plane shape and a complex three-dimensional shape can be processed; moreover, the fireproof heat-insulating plate provided by the invention is provided with the resin edge-sealing layer, so powder leakage at the edge can be avoided, and the whole fireproof heat-insulating plate is more suitable for heat insulation inside precision equipment.

Description

technical field [0001] The invention relates to the technical field of heat insulation materials, and more specifically relates to a fireproof heat insulation board and a preparation method thereof. Background technique [0002] Traditional thermal insulation materials are divided into inorganic type and organic type, among which the organic type is mainly various polymer foams, such as polyurethane (PU), polyimide (PI), polymethacrylimide (PMI), etc., The defects of organic heat insulation materials are mainly easy to absorb water, the temperature resistance is difficult to exceed 300 ℃, and the sound insulation performance is slightly poor; the inorganic types are mainly glass fiber, silicate fiber, etc. The defects of inorganic heat insulation materials are mainly poor heat insulation performance, Heavy weight. Compared with traditional thermal insulation materials, airgel and related products have great advantages in thermal insulation performance, but there are also so...
