Above-mentioned hot melt laminating refers to by first heating blending glass-fiber-fabric, PP sheet/film, then fit to the plastic honeycomb core of normal temperature in advance; The temperature of hot melt laminating is 180 DEG C ~ 230 DEG C; Before hot melt laminating, preferentially pre-compacted is carried out to heated blending glass-fiber-fabric and PP sheet/film etc.Pre-compacted can roll with one or more groups roller.
The preparation method of above-mentioned honeycomb board specifically can adopt following several mode to implement:
Mode 1:
Above-mentioned hot melt binding temperature is 210 DEG C.Before above-described hot melt laminating, preferentially pre-compacted is carried out to heated blending glass-fiber-fabric and PP sheet/film etc.; Above-described pre-compacted adopts one group of roller to roll; Above-described MODIFIED PP sheet/film is made up of 5% talcum powder modification, and infiltrate through non-woven fabrics simultaneously, and be individual layer compound, thickness is 0.4mm.Above-mentioned sander use the mode be arranged in juxtaposition before and after two sand rollers, the rise and fall of two sand rollers are all servo lift., containing shower system, spray water with high pressure to abrasive band and sheet material in above-mentioned sander inside; Above-mentioned sander preferably increases washing apparatus for drying; The cellular thermoplastic compound coating flat sheet surface gloss produced is high, and flatness is good, has plane (minute surface) effect.
Mode 2:
Above-mentioned hot melt binding temperature is 220 DEG C.Before above-described hot melt laminating, preferentially pre-compacted is carried out to heated blending glass-fiber-fabric and PP sheet/film etc.; Above-described pre-compacted adopts one group of roller to roll; Above-described MODIFIED PP sheet/film is without any filler, and infiltrate through non-woven fabrics simultaneously, and be individual layer compound, thickness is 0.8mm.Above-mentioned sander use the mode be arranged in juxtaposition before and after two sand rollers, the rise and fall of two sand rollers are all servo lift., containing shower system, spray water with high pressure to abrasive band and sheet material in above-mentioned sander inside; Above-mentioned sander preferably increases washing apparatus for drying; The cellular thermoplastic compound coating flat sheet surface gloss produced is high, and flatness is good, has plane (minute surface) effect.
Mode 3:
Above-mentioned hot melt binding temperature is 210 DEG C.Before above-described hot melt laminating, preferentially pre-compacted is carried out to heated blending glass-fiber-fabric and PP sheet/film etc.; Above-described pre-compacted adopts one group of roller to roll; Above-described surface layer 1 MODIFIED PP sheet/film is made up of 35% talcum powder modification, and infiltrate through non-woven fabrics simultaneously, and be individual layer compound, thickness is 0.8mm.Above-mentioned sander use the mode be arranged in juxtaposition before and after two sand rollers, the rise and fall of two sand rollers are all servo lift., containing shower system, spray water with high pressure to abrasive band and sheet material in above-mentioned sander inside; Above-mentioned sander preferably increases washing apparatus for drying; Sheet material thus after Material cladding, through repeatedly polishing, surface smoothness is all difficult to produce a desired effect, and enters back segment coating process as wanted, superfine abrasive band must be used repeatedly to polish, and so causes cost uncontrollable and efficiency is extremely low.So this scheme cannot reach the effect of this invention.
Mode 4:
Above-mentioned hot melt binding temperature is 230 DEG C.Before above-described hot melt laminating, preferentially pre-compacted is carried out to heated blending glass-fiber-fabric and PP sheet/film etc.; Above-described pre-compacted adopts one group of roller to roll; Above-described surface layer 1 MODIFIED PP sheet/film is made up of 15% talcum powder modification, and infiltrate through non-woven fabrics simultaneously, and be two-layer compound, thickness is 2.0mm.Above-mentioned sander use the mode be arranged in juxtaposition before and after two sand rollers, the rise and fall of two sand rollers are all servo lift., containing shower system, spray water with high pressure to abrasive band and sheet material in above-mentioned sander inside; Above-mentioned sander preferably increases washing apparatus for drying; Sheet material thus after Material cladding, because PP sheet material is thicker, is not effective after pressure roller pre-compacted compound, and its Partial Physical Property and the moulding honeycomb board gap of ordinary hot are comparatively large, therefore the present invention loses meaning.So this scheme cannot reach the effect of this invention.
Mode 5:
Above-mentioned hot melt binding temperature is 215 DEG C.Before above-described hot melt laminating, preferentially pre-compacted is carried out to heated blending glass-fiber-fabric and PP sheet/film etc.; Above-described pre-compacted adopts one group of roller to roll; Above-described surface layer 1 MODIFIED PP sheet/film is made up of 15% talcum powder modification, and infiltrate through non-woven fabrics simultaneously, and be individual layer compound, thickness is 0.2mm.Above-mentioned sander use the mode be arranged in juxtaposition before and after two sand rollers, the rise and fall of two sand rollers are all Manual elevating type., containing shower system, spray water with high pressure to abrasive band and sheet material in above-mentioned sander inside; Above-mentioned sander preferably increases washing apparatus for drying; Sheet material thus after Material cladding, through repeatedly polishing, surface smoothness produces a desired effect, but the position of segment thickness tolerance on the upper side is through repeatedly polishing worn out for blending glass-fiber-fabric, can produce extreme influence to follow-up coating process.So this scheme cannot reach the effect of this invention.
As known from the above, all parameter configuration of mode 1 ~ 2 all in this patent scope of disclosure, by above parameter configuration under the honeycomb board made, plate surface glossiness is high, and flatness is good, has plane effect.
