Abstract
The invention provides a composite type reinforced phenol formaldehyde foam insulating sheet and a preparing method thereof. The insulating sheet comprises an upper surface layer (1), a middle layer (2) and a lower surface layer (3) which are mutually combined in sequence, the materials of the middle layer (2) are phenol formaldehyde foams, and the upper surface layer (1) and the lower surface layer (3) comprise a reinforced layer (101) made of fiber mat. The composite type reinforced phenol formaldehyde foam insulating sheet of the invention greatly improves the physical strength and the adhering performance through combining fiber reinforced materials on the surface of the phenol formaldehyde foam sheet, and widens the application area of the phenol formaldehyde foam insulating sheet.
Description
Technical field
The present invention relates to a kind of foam heat-insulating board, more particularly relate to a kind of pnenolic aldehyde foam heat-insulating board.
Technical background
Pnenolic aldehyde foam heat-insulating board has benefited from its distinctive high flame retardant characteristic, and market development is very fast at home in recent years.Especially the phenol formaldehyde foam sheet material of thickness about 20mm, the embossing aluminium foil of its surface recombination 0.07mm thickness is applied in the air conditioner ventilation pipeline as structural material, is subjected to the favorable comment in market.
As Chinese patent 02273147.4 a kind of composite pnenolic aldehyde foam heat-insulating board is disclosed, the Chinese patent 03106509.0 open composite board continuous manufacture method of phenol formaldehyde foam.
The manufacture method of conventional phenol formaldehyde foam sheet material generally can be divided into two classes according to its technology: discrete method production and continuous method production.
The phenol formaldehyde foam of bulk is normally produced in discrete method production earlier, foam is cut into certain thickness foam sheet again, then surface layer such as surface recombination aluminium foil and become composite insulating board;
It then is manufacturing mechanism by a kind of continization that continuous method is produced, and direct composite cover material in the process of phenol formaldehyde foam moulding is produced the composite phenol formaldehyde sheet material of specific thicknesses.
As everyone knows, phenol formaldehyde foam is a kind of foamed material of fragility, and this fragility is reflected on the composite phenol formaldehyde sheet material, makes sheet material produce two shortcomings: the one, and the insufficient strength of sheet material is big, is easy to efflorescence under damage of external force; The 2nd, the bonding strength of sheet material and surface layer is not high.

Said enhancement layer also comprises surface layer outward, and the material of said surface layer is selected from paper material or aluminium foil.Paper material such as kraft paper, but the composite kraft paper that gram new material Co., Ltd produces in the Jiangyin City; Said aluminium foil, the thickness that ripe Aluminum Foil Factory as usual is produced is the aluminium foil of 0.07mm and the aluminium foil of 0.03mm.This aluminium foil can directly use, and also can use after the embossing.Surface layer and enhancement layer carry out compound by adhesive as neoprene.
Composite reinforced pnenolic aldehyde foam insulating board of the present invention can adopt the production technology of discrete method, comprises the steps:
Bottom surface at mould, at first lay fibrous felt materials, the phenolic resin raw material that mixes is poured in the mould, and then covering one deck fibrous felt materials, matched moulds, the phenolic resin raw material is the foamed solidification moulding in mould, opens mould, obtain fibre-reinforced pnenolic aldehyde foam heat-insulating board, use the compound said surface layer of adhesive then;
The composite reinforced pnenolic aldehyde foam insulating board of invention also can adopt the production technology of continuous method, comprises the steps:
Two-layer fibrous felt materials is up and down entered in the machine laminated into type with cavity continuously, the phenolic resin raw material that mixes in the surperficial continuous pouring of lower floor's fibrous felt materials, the phenolic resin raw material is the foamed solidification moulding in the cavity of machine laminated into type, cutting, become sheet material, use the compound said surface layer 102 of adhesive then, obtain fibre-reinforced pnenolic aldehyde foam heat-insulating board.
Employed phenolic resin raw material comprises: auxiliary agents such as the thermoset phenolic resin that phenol and formaldehyde condensation form, stabilizer, foam stabilizing compound, acid catalyst, the density of phenol formaldehyde foam is generally between 30～100kg/m3.This phenolic resin and foam process thereof can be with reference to U. S. Patent U.S.Pat.No.4,165,413.
Composite reinforced pnenolic aldehyde foam insulating board of the present invention, the surface recombination fibre reinforced materials by at phenol formaldehyde foam sheet material improves its physical strength and adhesive property greatly, has expanded the application of pnenolic aldehyde foam heat-insulating board.
