Abstract
The present invention discloses a preparation method of a sandwich structural plate, which belongs to a building material technology. The present invention is orderly proceeded according to the following steps: the surfaces of a base plate and a panel are respectively sprayed with glue; the glue sprayed surfaces of the base plate and the panel are respectively combined with honeycomb-shaped plates; the glue is solidified and bonded. The present invention is characterized in that the glue solidifying and bonding step is proceeded under the conditions of a normal temperature and a negative voltage. The present invention has the characteristics of little energy consumption, no pollution on production sites, high bonding fastness, etc. Products prepared from the present invention are ideal materials for modern architectural decoration.
Description
Technical field
The invention belongs to building material technology, be specifically related to a kind of preparation method who is used for the sandwich structure plate of decorations such as building, the vehicles.
Background technology
The sandwich structure plate, this is its trade name, insider's custom call.It is to form the bonding method of the bonding employing heating cure of the curing of its adhesive by base plate, cellular board and panel through adhesive is bonding.Obviously, the prior art of this bonding of heating, it is big to exist energy consumption, and the production on-site environment situation is poor, and glue is easy to generate micro air bubble, and influences deficiency such as adhesive fastness.Japan Patent JP7-180281 discloses a kind of " cellular multi-layer sheet and manufacture method thereof ", the cellular multi-layer board manufacturing method of wherein listing is the vacuum bag molding that utilizes pressure sintering, autoclave molding or vacuum, by add depress the heating integrally formed.But the document does not relate to for vacuumizing which kind of degree of arrival, the adhesive that is adopted is solid-state fiber-reinforced resin plate, fiber-reinforced resin plate fusing back is solidified, thus cause equipment complexity, cost higher, limited production-scale expansion; Because under heated condition, solidify,, easily in product, generate bubble and influence quality though curing rate is very fast.
Summary of the invention
The objective of the invention is to: provide that a kind of energy consumption is less, the production scene is pollution-free substantially, can effectively prevent exempting from producing bubble, and guarantee the preparation method of the sandwich structure plate of bonding fastness, to overcome the deficiency of prior art in the abutting edge.
The objective of the invention is to take following technical scheme to realize.It carries out according to following steps successively: respectively at base plate and panel surface spray polyurethane adhesive; Base plate and panel spray glue face is compound with the positive and negative of cellular board respectively; Compound is put into airtight storehouse, and normal temperature starting evacuator down forms negative pressure in airtight storehouse; Polyurethane adhesive solidifies under the normal temperature negative pressure and base plate, cellular board and panel are adhesively fixed successively is in the same place, and makes finished product.
Above-mentioned base plate is aluminium sheet, flame retardant plastics plate, colored sheet metal, fire-retardant wood fibre board or PLASTIC LAMINATED, cellular board is aluminum honeycomb panel, plastic honeycomb board or good quality paper cellular board, panel is aluminium sheet, color steel, corrosion resistant plate, titanium alloy sheet, flame retardant plastics plate or PLASTIC LAMINATED, it is-0.2 to-0.8MPa that polyurethane adhesive solidifies bonding condition of negative pressure, to satisfy the chemico-physical properties of polyurethane adhesive.According to user's needs, can also between the gap of cellular board, be filled with foamed plastic, with effects such as the insulation of further raising manufactured goods of the present invention, sound insulations.
The present invention has positive effect: compared with the prior art, not only adhesive fastness is big, fragility is little, freeze-thaw resistance is strong for the normal temperature cured type liquid polyurethane class adhesive that the present invention adopts, and can solidify at normal temperatures, thereby make energy consumption less, production on-site environment does not have pernicious gas and pollutes, adhesive can not produce bubble, thereby can effectively improve cellular multiple-plate bonding fastness in solidifying bonding process.Thereby the present invention has outstanding substantive distinguishing features and obvious improvement.
Description of drawings
Fig. 1 is the structure cutaway view of a kind of sandwich structure plate of employing the present invention preparation.
The specific embodiment
(embodiment 1)
See Fig. 1, the preparation method of present embodiment carries out according to the following steps: evenly spray polyurethane adhesive on the surface of base plate aluminium sheet 1 and panel aluminium sheet 3 by the venturi type sprayer respectively; Aluminum honeycomb panel 2 is stretched shaping, and the spray glue face of base plate aluminium sheet 1 and panel aluminium sheet 3 is in the same place with the obverse and reverse overlapping of aluminum honeycomb panel 2 respectively, obtain compound; Above-mentioned compound is inserted in the airtight storehouse of special equipment, the starting evacuator when treating to be depressed in the airtight storehouse-0.35 to-0.45MPa, was kept 8 hours, then polyurethane adhesive solidifies and base plate, cellular board and panel is adhesively fixed successively be in the same place, and makes finished product.
The sandwich structure plate that the present invention makes, again through deburring, shaping, check, packing, sale can appear on the market.
(embodiment 2)
Base plate 1 in the present embodiment adopts colored sheet metal, and cellular board 2 adopts the good quality paper cellular boards, and panel 3 adopts PLASTIC LAMINATEDs, and condition of negative pressure is-0.6 to-0.8MPa, and other is then as embodiment 1.
(embodiment 3)
Base plate 1 in the present embodiment adopts aluminium sheet, and cellular board 2 adopts plastic honeycomb boards, and panel 3 adopts the flame retardant plastics plates, and condition of negative pressure is-0.2 to-0.4MPa, and other is then as embodiment 1.
Base plate 1 of the present invention, cellular board 2, panel 3 can adopt previous materials to be configured according to user's needs, and its configuration combination is not subjected to the described restriction of this specification.
The finished product sandwich structure plate that the present invention is prepared detects through national building materials test center, and every index all meets or exceeds state quality standard, and wherein freezing-thawing test shows, its performance indications have more gratifying result.
