Description
Technical field
The present invention relates to fireproof structural material technical field, specifically a kind of basalt fibre enhances phenolic board
The moulding process of sandwich PMI composite plate.
Background technique
Existing sandwich composite board, such as aluminum honeycomb panel, light core steel, there is certain Pros and Cons, such as aluminum honeycomb
Plate is heavier, and high temperature lower panel can be completely disengaged with core material；Light core hardness of steel is too low, is unable to satisfy requirement.
Currently, basalt fibre reinforced epoxy plate sandwich PMI composite plate has been had comprehensive well using flame retardant epoxy
Close performance.This battenboard is made using the PMI foamed material of high-strength light as core material with the epoxy plate of basalt fibre enhancing
For upper and lower panel, formed by lamination or vacuum bag technique one-pass molding, with good fire protecting performance and high-strength light
Performance.But this battenboard still will appear a large amount of white cigarette when contacting open fire, and have the combustion phenomena of short time,
Therefore it is not used as fire protecting performance and requires higher material.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, it is compound to provide a kind of basalt fibre enhancing phenolic board sandwich PMI
The moulding process of plate.
In order to solve the above technical problems, the present invention is addressed by following technical proposals: a kind of basalt fibre enhancing
The moulding process of phenolic board sandwich PMI composite plate, it includes the profound of upper layer which, which enhances phenolic board sandwich PMI composite plate,
Military rock fibre reinforced phenolic plate, PMI cystosepiment and the basalt fibre of lower layer enhance phenolic board, the basalt on the upper layer
Between fibre reinforced phenolic plate and the PMI cystosepiment and the basalt fibre of the lower layer enhances phenolic board and the PMI
It is bonded by adhesive layer between cystosepiment；
The step of its moulding process, is as follows:
One, production basalt fibre enhances phenolic board: 1., prepare mold, glues adhesive tape in Mould operation face surrounding, then
The coating release agent on the operating surface；2., the laying on Mould operation face；3., tile release cloth above laying；4., demoulding
Corresponding auxiliary material and diversion pipe are spread above cloth；5., tear adhesive tape, sealing joint strip is pasted to the ground for tearing adhesive tape
Side cuts exhaust tube and forms No.1 exhaust tube, and No.1 exhaust tube is connect with diversion pipe and at least 50cm stays in mold exterior, together
When No.1 exhaust tube is connect with the sealing joint strip on mold with sealing joint strip；6., vacuum bag film pasted on sealing joint strip
Form closed system；7., cut exhaust tube and form No. two exhaust tubes, with No. two exhaust tubes connection pumped vacuum systems and stay in mold
External No.1 exhaust tube forms the pipeline that can pump closed system inner air；8., open vacuum pump, to entire obturator
System vacuumizes, and examines vacuum degree whether to reach -0.095MPa or more and stablizes；9., entire closed system is put into baking oven baking
Solidification；10., baking after the completion of, close vacuum pump, take out molds and products, demoulding obtain basalt fibre enhancing phenolic board；
Two, bond:, cut basalt fibre enhancing phenolic board, by the basalt fibre cut enhance phenolic board put
Enter baking 12-24h in the baking oven that temperature is 80-100 DEG C and removes free aldehyde and water；, prepare laminated mould, coating release agent；⑬,
Spread basalt fibre enhancing phenolic board, adhesive layer and PMI cystosepiment respectively by product structure on mold；, molding；⑮,
Lamination solidification；, cut to obtain product.
In above-mentioned technical proposal, it is preferred that when step 2. middle berth be fiber dry cloth when, step 4. in auxiliary material be water conservancy diversion
Net, and step 8. after, resin is imported in closed system by diversion pipe.
In above-mentioned technical proposal, it is preferred that when step 2. middle berth be phenolic aldehyde prepreg when, step 4. in auxiliary material be
Gas felt.
In above-mentioned technical proposal, it is preferred that when step 2. use hand paste process and paving be fiber dry cloth when, step 4. in
Auxiliary material be airfelt.
In above-mentioned technical proposal, it is preferred that the adhesive layer is epoxy jelly membrane.
In above-mentioned technical proposal, it is preferred that the adhesive layer is that epoxy resin fills surface felt.
In above-mentioned technical proposal, it is preferred that the adhesive layer is that unsaturated polyester resin fills surface felt.
The beneficial effects of the present invention are: the present invention, using PMI cystosepiment as core material, PMI cystosepiment is different from traditional phenol
Aldehyde cystosepiment, polystyrene foam plate etc. have the up to compression strength of 4MPa and less than 150kg/m3Density, lightweight is high
By force；Enhance phenolic board as upper and lower panel using basalt fibre, chance open fire does not burn and smoke amount is few, can protect well
PMI cystosepiment, and the biggish defect of PMI cystosepiment brittleness is solved, to reach the characteristic of non-ignitable low cigarette and high-strength light.
However, phenolic cure can generate moisture in the process, and PMI cystosepiment chance water will cause strength reduction, furthermore phenolic aldehyde
There are free aldehyde to need to remove in forming process to body nocuousness.Therefore, traditional one-pass molding scheme is not all suitable for
The production of basalt fibre sandwich PMI composite plate.The present invention uses the technical solution of post forming, and it is fine that the first step completes basalt
After the production of dimension enhancing phenolic board, by baking drop low-free formaldehyde and most of moisture can be removed, reduce moisture to PMI foam
The influence of plate, to solve the difficult point in forming process.In addition, basalt fibre enhance phenolic board compared to PMI cystosepiment at
This is lower, and underproof basalt fibre can be enhanced to phenolic board removal before second step adhesion process, to improve PMI bubble
The utilization rate of foam plate reduces risk.
