Problems solved by technology

[0002] In order to improve the integrity and impact resistance of the insulation board, the foamed cement insulation board and fiber-reinforced composite insulation board on the market are mostly reinforced by coating glass fiber mesh cloth with cement slurry on both sides or one side of the insulation board. Although this method effectively improves the toughness and crack resistance of the insulation board, it needs at least 2-3 days of curing time due to the cement slurry coating process on the surface, which not only increases the production cycle of the insulation board, but also due to the insulation There is cement slurry on the surface of the board, which cannot be superimposed on each other, so it generally needs to be maintained on a shelf, so the fixed investment in production is increased

Abstract

The invention discloses a glass fibre tissue compound heat-insulating plate and a preparation method for the same. The heat-insulating plate comprises a heat-insulating layer, an adhesive and a glass fibre tissue veneer material layer, wherein the inner side of the glass fibre tissue veneer material layer is adhered on the surface of the heat-insulating layer via the adhesive. The preparation method comprises the following steps of: preparing the adhesive; producing the heat-insulating layer; brushing an interface agent on the inner surface of the glass fibre tissue veneer material layer; adhering the inner side of the glass fibre tissue veneer material layer which is subjected to interface treatment on the surface of the heat-insulating layer via the adhesive; and directly superposing and packaging compound heat-insulating plates which are adhered with the glass fibre tissue veneer material layers on the surfaces, and standing for 1-3 days. According to the invention, the compound heat-insulating plates can be mutually superposed, stacked and directly packaged while the integrity of the compound heat-insulating plates is enhanced; in this way, production cycle is saved, and maintenance on a shelf is avoided, thus reducing production cost and increasing production efficiency.
