Close performance.This battenboard, using the PMI foamed materials of high-strength light as core, made with the epoxy plate of basalt fibre enhancing
For upper and lower panel, formed by lamination or vacuum bag technique one-shot forming, there is good fire protecting performance and high-strength light
Performance.But substantial amounts of white cigarette still occurs when contacting naked light in this battenboard, and the combustion phenomena of short time is had,
Therefore it is not used as the material that fire protecting performance requires higher.
The content of the invention
The present invention be directed to deficiency of the prior art, there is provided a kind of basalt fibre strengthen phenolic aldehyde sandwich composite board and its
Moulding process.
In order to solve the above technical problems, the present invention is addressed by following technical proposals：A kind of basalt fibre enhancing
Phenolic aldehyde sandwich composite board, including the basalt fibre enhancing phenolic board on upper strata, PMI cystosepiments and the basalt fibre of lower floor increase
Strong phenolic board, the basalt fibre on the upper strata strengthen between phenolic board and the PMI cystosepiments and the lower floor it is profound
Bonded between military rock fibre reinforced phenolic plate and the PMI cystosepiments by adhesive layer.
In above-mentioned technical proposal, it is preferred that a kind of moulding process of basalt fibre enhancing phenolic aldehyde sandwich composite board, it is walked
It is rapid as follows：
First, basalt fibre enhancing phenolic board is made：1., prepare mould, in Mould operation face surrounding glue adhesive tape, then
The coating release agent on the operating surface；2., the laying on Mould operation face；3., tile release cloth above laying；4., be stripped
Corresponding auxiliary material and mozzle are spread above cloth；5., tear adhesive tape, sealing joint strip is pasted to the ground for tearing adhesive tape
Side, cut exhaust tube and form No.1 exhaust tube, No.1 exhaust tube is connected with mozzle and at least 50cm stays in mold exterior, together
When No.1 exhaust tube is connected with the sealing joint strip on mould 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, connect pumped vacuum systems with No. two exhaust tubes and stay in mould
Outside No.1 exhaust tube, form the pipeline that can pump closed system inner air；8., open vavuum pump, to whole obturator
Whether system vacuumizes, examine vacuum to reach more than -0.095MPa and stably；9., whole closed system is put into baking oven baking
Solidification；10., baking after the completion of, close vavuum pump, take out molds and products, the demoulding obtain basalt fibre enhancing phenolic board；
2nd, bond：Basalt fibre enhancing phenolic board is cut, the basalt fibre cut enhancing phenolic board is put
Enter baking 12-24h in the baking oven that temperature is 80-100 DEG C and remove free aldehyde and water；Prepare laminated mould, coating release agent；Spread basalt fibre enhancing phenolic board, adhesive layer and PMI cystosepiments respectively by product structure on mould；Matched moulds；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, by mozzle toward importing resin in closed system.
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. using hand paste technique and paving be fiber dry cloth when, step 4. in
Auxiliary material be airfelt.

The beneficial effects of the invention are as follows：For the present invention using PMI cystosepiments as core, PMI cystosepiments are different from traditional phenol
Aldehyde cystosepiment, polystyrene foam plate etc., there is up to 4MPa compression strength and the density less than 150kg/m3, lightweight height
By force；Phenolic board is strengthened as upper and lower panel using basalt fibre, chance naked light does not burn and smoke amount is few, can protect well
PMI cystosepiments, and solve the defects of PMI cystosepiment fragility is larger, so as to reach the characteristic of non-ignitable low cigarette and high-strength light.
However, can produce moisture during phenolic cure, and PMI cystosepiments meet water can cause intensity decreases, in addition phenolic aldehyde
It is harmful to body, it is necessary to be removed in forming process in the presence of free aldehyde.Therefore, traditional one-shot forming scheme is not all suitable for
The making of basalt fibre sandwich PMI composite plates.The present invention uses the technical scheme of post forming, and it is fine that the first step completes basalt
After the making of dimension enhancing phenolic board, you can by toasting drop low-free formaldehyde and removing most of moisture, reduce moisture to PMI foams
The influence of plate, so as to solve the difficult point in forming process.In addition, basalt fibre strengthen phenolic board compared to PMI cystosepiments into
This is relatively low, and underproof basalt fibre can be strengthened into phenolic board before second step adhesion process removes, so as to improve PMI bubbles
The utilization rate of foam plate, reduce risk.
