Description
Technical field
The present invention relates to building field, refer to especially a kind of CO
2With building composite board of thermosetting resin and preparation method thereof.
Background technology
At present; be attached to the architectural engineering wall outer side and body of wall played the building board of protection, decoration function; usually divide metal, nonmetal and metal and nonmetal three kinds of the classes of mixing; metal species is commonly used aluminium-plastic panel and a color steel veneer, and non-metal kind is commonly used stone material, ceramic panel and fibre cement flat board etc.Building board generally adopts with being connected of base course wall the method that keel is arranged or fix without keel machinery, and adopts the directly method of stickup of special-purpose adhesive or cement slurry.In keel machinery fixing means is arranged, adopt the metal joist high cost, and need to consider the Anticorrosion of keel; Utilize timber to make keel and can only be used in place without water erosion, and service life is short.In without keel machinery fixing means, generally because mechanical strength is low, only be suitable for the architectural application at lower level, and have larger limitation.The method that adopts special-purpose adhesive or cement slurry directly to paste, there is larger mass defect, namely two different rigid materials of the coefficient of expansion are bonded in one, being subjected to temperature, humidity to change the internal stress that produces is concentrated on bonding plane, prolonged and repeated effect can cause the sheet material cracking, come off, and affects result of use.
The blowing agent that uses in disclosed thermosetting resin building composite board production now has: 1, fluorine-containing blowing agent, 2, contain alkane blowing agent, 3, property of water-bearing blowing agent.Contain the freon material that damages the atmosphere protection layer in the first blowing agent; The second blowing agent is deposited the danger that the accumulative total of concentration is aborning blasted; There is the high shortcoming of the thermal conductivity factor of core in the third blowing agent.
Summary of the invention
The present invention proposes a kind of CO
2With the building composite board material, preparation method of thermosetting resin, solved the problem of the anti-folding of composite board, bending resistance and contaminated environment in the prior art.
Technical scheme of the present invention is achieved in that
A kind of CO
2With the building composite board material, preparation method of thermosetting resin, this preparation method comprises the steps:
Step 1: by can decompression, the mixing arrangement of temperature control and flow control is CO
2Mix with the one-component material in thermosetting resin;
Step 2: the many component materials in mixed raw material and thermosetting resin in described step 1 are mixed by injection device;
Step 3: the mixture in step 2 is injected the sheet material sandwich of layers, make the heat curing-type building composite board.
Preferably, the mixing arrangement in described step 1 is static mixer.
Preferably, described thermosetting resin is phenolic resins or polyurethane; Further, when described thermosetting resin was thermoset phenolic resin, described multi-component material was phenolic resins, fire retardant, smoke suppressant and closed pore agent, and described one-component material is the curing agent in phenolic resins; When described thermosetting resin was polyurethane, described multi-component material was combined polyether or combination polyester, fire retardant, smoke suppressant and the closed pore agent in polyurethane, and described one-component material is the isocyanates in polyurethane.
Preferably, described step 2 is further: with CO
2After mixing with one-component material in thermosetting resin, mix with the mode of shock or stirring with many component materials by syringe.
If with CO
2Carrying out premix with thermosetting resin one-component and many components raw material in advance can rush down leakage because producing in the process of raw material in return line or storage equipment, thereby must increase the sealing pressurize cost of equipment; If with CO
2Mixing with isocyanates in advance can be because of CO
2Temperature or the temperature difference of isocyanates produce dewfall, thereby cause crystallization reaction damage equipment and material.
The present invention also proposes a kind of building composite board, and this building composite board comprises internal layer, skin and sandwich of layers, and described sandwich of layers is according to described preparation method's injection mo(u)lding.
Preferably, described internal layer and outer the employing are not fired plate and are made.
Preferably, also be provided with heat-insulation layer in this building composite board.
Preferably, in this building composite board, pre-buried keel structure can also be set.
Beneficial effect of the present invention is:
1.CO
2Need not be before production mix with one-component or many components raw material in any thermosetting resin in advance as blowing agent, saved process.
2. the anti-pressure ability of the thermosetting resin building composite board of making by the present invention strengthens to some extent, has also avoided the environmental pollution that produces when the thermosetting resin building is compound produces with sheet material, thus the production cost of reduction sheet material.
Description of drawings
