Abstract

The invention relates to the technical field of construction energy-saving novel materials, and in particular relates to a process for preparing a phenolic foam composite plate. The process comprises the following steps: coating a waterborne polyurethane adhesive on surfaces of an upper metal panel and a lower metal panel, heating to form adhesive layers, putting a lignin modified phenolic resin foamed mixture between the upper metal panel and the lower metal panel, foaming and curing to form. By adopting the process, the problem that the phenolic foam composite plate is high in brittleness is solved, the phenolic foam obtained by foaming the modified phenolic resin is good in toughness, and due to improvement of the toughness of the phenolic foam, the area that the phenolic foam is adhered to the metal surface layer is increased, and the adhesion strength of the phenolic foam and a composite plate is further improved.

Description

Prepare the technique of phenolic foam composite plate material
technical field
The present invention relates to building energy conservation new material technology field, relate in particular to a kind of technique of preparing phenolic foam composite plate material.
Background technology
Phenolic foam composite plate material have lightweight, fire prevention, chance naked light do not burn, smokeless, nontoxic, without drippage, serviceability temperature is enclosed extensively (196~+ 200 ℃), does not shrink, the feature of not embrittlement under low temperature environment.Because phenol formaldehyde foam rate of closed hole is high, thermal conductivity factor low (can lower than 0.030w/mk), heat-proof quality is good, and has certain water-resistance and water vapour permeability, is good heat insulating energy saving material, especially the desirable heat-insulating material of HVAC Refrigeration Engineering.Because phenolic aldehyde has benzene ring structure, thus dimensionally stable, rate of change <1%.And chemical composition stability, anticorrosion anti-aging, particularly ability organic solution, strong acid, weak base corrosion.So phenolic foam composite plate is very good fire prevention, thermal insulation, environment-friendly and green insulation material energy-conservation, attractive in appearance.
Cementability between existing phenol formaldehyde foam and phenol formaldehyde foam surface sheet material are compound is not strong, bonding not firm, while carrying out secondary operations after manufacturing a finished product, easily departs from, easily peeling.The patent No. is that CN 101214746 B disclose one by being evenly coated with last layer composite glue at panel, through being dried to sticky hand, then compound under heating backer roll with incombustible glass fibre goods, after compound through dry composite panel, the method has improved bonding intensity of phenolic foam composite sheet material greatly.But the use of compound adhesive not only makes production cost improve, and contaminated environment, makes the phenolic foam composite plate material that production of resins goes out have very large fragility because phenolic resins contains this rigid structure of phenyl ring simultaneously.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of preparation method of phenolic foam board, the method not only reduces compound adhesive and uses the environmental pollution causing, and solves the problem that composite board fragility is large simultaneously, and has further improved phenol formaldehyde foam sheet material adhesive strength.
The invention provides a kind of technique of preparing phenolic foam composite plate, comprise the following steps:
At upper metal decking and lower metal decking apparent surface, all apply aqueous polyurethane glue, at 30-70 ℃, add thermosetting glue-line;
Lignin modification phenol resin foam mixture is placed between described upper metal decking and lower metal decking, foams, obtain phenolic foam composite plate material after curing molding;
Wherein said lignin modification phenol resin foam mixture is by 100 parts, lignin modification phenolic resins, 2 parts of emulsifying agents, 2 parts of fire retardants, 5 parts of blowing agents, 10 parts of compositions of curing agent.
Preferably, the temperature of described heating glue formation glue-line is 45-55 ℃.
Preferably, described aqueous polyurethane glue is comprised of two kinds of components of black and white material, and black and white material ratio is 2-5:1.
Preferably, described upper metal decking and lower metal decking are color steel.
The present invention also provides a kind of preparation method of phenolic foam board, comprises the following steps:
In upper metal decking or lower metal decking opposite face, one side applies aqueous polyurethane glue, adds thermosetting glue-line at 30-70 ℃;
Lignin modification phenol resin foam mixture is placed between described upper metal decking and lower metal decking, foams, obtain phenolic foam composite plate material after curing molding;
Wherein said lignin modification phenol resin foam mixture is by 100 parts, lignin modification phenolic resins, 2 parts of emulsifying agents, 2 parts of fire retardants, 5 parts of blowing agents, 10 parts of compositions of curing agent.
Preferably, the temperature of described heating glue formation glue-line is 45-55 ℃.
Preferably, described glue is comprised of two kinds of components of black and white material, and black and white material ratio is 2-5:1.
Preferably, the metal decking of described surperficial glue coated is color steel.
Preferably, described surface not the metal decking of glue coated be aluminum foil plate.
Preferably, described aluminum foil plate inner surface is covered with plucking nonwoven.
Compared with prior art, the present invention uses aqueous polyurethane glue as compound adhesive, phenolic resins is carried out to modification, serviceability temperature control and lignin modification phenolic resins to aqueous polyurethane glue are processed simultaneously, solve phenolic foam composite plate material and have very large fragility problem.Wherein, aqueous polyurethane glue utilizes water as solvent, has reduced the pollution to environment.Lignin modification phenolic resins is on phenyl ring, to introduce the long carbochain of toughness, by the phenol formaldehyde foam obtaining that phenol-formaldehyde resin modified is foamed, there is good toughness, the raising of phenol formaldehyde foam toughness increases phenol formaldehyde foam and metal faced bond area, has further improved the adhesion strength of phenol formaldehyde foam and composite board.
