(1), the preparation of pipe comb core;
Get PP collagen grain, utilize the High-temperature Liquefaction of 270 DEG C, extruder air pressure controls at 0.4 ~ 0.5kPa, is extruded into the pipe of 0.15mm ~ 0.25mm thickness by plastic extruder; Then pipe comb core is arranged in;
(2), get glass fabric two, carry out composite plate hot pressing; Hot pressing temperature is 200 DEG C, and pressure is 0.4Kpa, and hot pressing time is 45s, allows glass fabric top layer and pipe comb core top layer merge, then takes out;
(3) product, got in step (2) carries out colding pressing fixed-type; Pressure of colding pressing is 0.4Kpa, and the time of colding pressing is 75s, allows fiberglass skin and pipe comb core merge crystallisation by cooling;
(4), obtained finished product.
The diameter of the pipe of the pipe comb core in described step (1) is 3 ~ 14mm.
The thickness of the glass fabric in described step (2) is 0.6mm, is of a size of 300mm*300mm.
Enhancing core is provided with between adjacent two pipe base cores in described step (1); Strengthening core is " work " type cross section.
Pipe base core in described step (1) is that the pipe of more than one diameters combines.
The present invention, relative to prior art, has following advantage and effect:
1, the present invention adopt manufacture method, have compound difficulty low, have the features such as high-strength light, waterproof anti-corrosion, not yielding, reusable, easy reparation, long service life and environmental protection.
2, the product that the method in the present invention is made into, quality is light (for the product in 6mm aperture, density is 85KG/m3, the quality of timber is 540KG/m3, the density of aluminium alloy is probably 2500KG/m3), extensive use means of transport envelope and box for material circulation, alleviate the weight of means of transport own, improves California bearing ratio.
3, the product that the method in the present invention is made into, waterproof anti-corrosion, and timber and aluminium alloy are all non-watertight not corrosion-resistant.Be widely used in wind power equipment external surface layer structure, swim raft at sea, and harbour is built.
4, the product that the method in the present invention is made into, resistance to compression anti-impact force is strong, and this is because the alveolate texture of I-shaped structure and composite board core material can absorb applied external force, thus significantly alleviates shocks, collides the destruction of bringing, and is mainly used in making and drops case.
5, the product that the method in the present invention is made into, sound insulation value is superior, because the alveolate texture that composite board core material is special, can effectively reduce damping vibration and absorb noise, being mainly used in the constructional ornamental material to the high place of sound isolation requirement.
6, the product that the method in the present invention is made into, heat-proof quality is superior, because composite plate comb core energy-absorbing effect own is superior, extremely low thermal insulation properties effectively stops the propagation of heat energy, make inner temperature relatively stable, be mainly used in the construction material of freezer and the envelope material of refrigerator car.
