Description
Technical field
The present invention relates to technical field of composite materials, specifically a kind of Wrapping method of plastic honeycomb battenboard.
Background technology
Honeycomb sandwich structure has the characteristics of in light weight, intensity is high because of hollow structure, has on cover plate of spare tire of automobile
It is widely used.
Common cellular sandwich spare tire cover plate has two kinds of materials, and one kind is PHC plates（Paper HoneyComb abbreviation, gather
Urethane spraying coating process）, core is honeycomb paper, and epidermis is glass fiber reinforced polyurethane foam, and another kind is plastic honeycomb battenboard, table
Skin is fiberglass reinforced plastics, and core is plastic honeycomb.In plastic honeycomb battenboard, compare typically PP honeycomb sandwich boards, letter
Claim PPHC plates（PolyPropylene HoneyComb abbreviation, dry process）, core is PP honeycombs, and epidermis is fiberglass reinforced
PP。
PPHC cover plates have the advantages of material recoverable, equipment cost are low, production efficiency is high, and with more preferable
Water proofing property and odor profiles, so increasingly being favored by main engine plants.
But PPHC sheet materials form generally by the compacting of continuous equipment complex, the edge after cutting is as shown in figure 1, side
Edge directly exposes the honeycomb core of centre, and low intensity, feel is bad.
A kind of conventional technology, which is that hot material chill is crowded, cuts.After sheet material heating, with the mould of cooling come compressing, and side
Edge squeezes off, while realizes the shaping of sheet material and the closing at edge.But containing glass in upper lower epidermis, intensity is very high, middle
Plastic honeycomb core intensity is poor, thus mould squeeze cut when, epidermis do not allow it is pliable, be also easy to centre honeycomb core shrivel,
Cause the edge of product as shown in Fig. 2 edge is very sharp, not plentiful, outward appearance is poor.
In addition, also there is the technique using cold burden hot-die, the edge of sheet material is heated by mould, and epidermis softening is even melted,
Honeycomb core is shriveled in the presence of mould and is bonded together.Because being heated in mould, the softening degree of epidermis is more preferable
Some, edge ought to be more plentiful.But because when mould is opened, material is still heat, so upper lower epidermis is easy
Open again, cause border seal to fail.
In a word, the border seal of plastic honeycomb battenboard is still technical barrier in the industry.
Comparatively, PHC cover plates are directly using honeycomb paper, Chopped Strand Mat and polyurethane material as raw material, using polyurethane coating
