Modified phenolic aldehyde composite insulation board and preparation method thereof

Abstract

The invention relates to a modified phenolic aldehyde composite insulation board and a preparation method thereof. The modified phenolic aldehyde composite insulation board comprises a modified phenolic aldehyde insulation board, adhesion agent layers, and quartz sand layers; and the adhesion agent layers are arranged on upper and lower surfaces of the modified phenolic aldehyde insulation board respectively and are provided with the quartz sand layers. The adhesion agent layers are coated on the double surfaces of the modified phenolic aldehyde insulation board, the thickness of the adhesion agent layers is 1 to 2mm, quartz sand is compounded on the two surfaces by a compression roller through two-surface laminating, the thickness of each quartz sand layer is 2 to 3mm, and then the modified phenolic aldehyde insulation board is fed into drying equipment by an automatic rolling platform and is dried and cured. The insulation board is convenient to construct at site, short in construction period, low in cost and high in quality; and the safety and the economy of the modified phenolic aldehyde composite insulation board are guaranteed.

Description

technical field [0001] The invention relates to an external wall thermal insulation material, in particular to a modified phenolic composite thermal insulation board for a thin plastering system and a preparation method thereof. Background technique [0002] At present, the building exterior wall insulation materials are mainly EPS polystyrene board, XPS extruded board, PU polyurethane board. These products are easy to burn, with large smoke, high toxicity, and extremely poor fire resistance when burning. They will melt, deform, and drip at 80°C. The fire spreads rapidly, and the fireproof performance of the external wall insulation material of this structure is poor, so it is impossible to achieve both energy saving and fire prevention. If there is a fire hazard, it is easy to cause casualties and environmental pollution. [0003] The phenolic insulation board is known as the "King of Thermal Insulation". As a new generation of thermal insulation and fireproof material, i...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the disadvantages of traditional phenolic insulation boards such as poor bonding performance, easy to fall off, hollowing, slow drying speed, large shrinkage, long construction period, high cost, low quality, etc. A modified phenolic composite insulation board with good bonding performance, low cost, convenient construction and stable performance has been developed. The preparation process is simple, the construction period is short, and the molding quality is high.
