Join polyethylene coiled material and modified glass-fiber cloth, obtains glass fiber and polyethylene composite sheet material；
(2) it is poly- that calibration arrangement hard-foam polyurethane plate, glass on upward bearing platform are transported away in glass fiber and polyethylene composite sheet material
The secondary correction of ethylene composite sheet material, calibration tension, so that the central axes of hard-foam polyurethane plate and glass fiber and polyethylene composite sheet material exist
In one plane, then under the pressure of 0.4-0.6MPa, hard-foam polyurethane plate hot melting cohesion is fitted in glass fiber and polyethylene and is answered
On the lower surface for closing coiled material, hard-foam polyurethane compound crosslinked polyethylene coiled material is obtained after cooling；
(3) to fixed length cutting before and after hard-foam polyurethane compound crosslinked polyethylene coiled material, quality inspection obtains the finished product hard-foam polyurethane
Compound crosslinked polyethylene pad.
The present invention produces hard-foam polyurethane compound crosslinked polyethylene pad using automatic assembly line, first by crosslinked polyethylene
Coiled material and modified glass-fiber cloth be arranged in it is homodromous rise on gas axis, by once rectify a deviation adjust crosslinked polyethylene volume
The position of material and modified glass-fiber cloth, so that crosslinked polyethylene coiled material and modified glass-fiber cloth central axes are vertical flat at one
In face, two rise and gas axis while rotating, and make it have viscosity, modified glass-fiber to the upper surface hot melt of crosslinked polyethylene coiled material
Cloth is final to collapse in a pressure roll slowly close to crosslinked polyethylene coiled material, bonds and is bonded through roll-in, obtains mechanics after cooling
The glass fiber and polyethylene composite sheet material that performance is reinforced；It is transported away in glass fiber and polyethylene composite sheet material on upward bearing platform and calibrates arrangement
Hard-foam polyurethane plate, the secondary correction of glass fiber and polyethylene composite sheet material simultaneously calibrates tension, so that hard-foam polyurethane plate and the poly- second of glass
The central axes of alkene composite sheet material in a plane, then heat the lower surface of glass fiber and polyethylene composite sheet material, are bonded hard bubble
Polyurethane sheet is bonded, and obtains hard-foam polyurethane compound crosslinked polyethylene plate after roll-in is cooling, at this point, sandwich structure
Hard-foam polyurethane compound crosslinked polyethylene plate is longer entirety, using the blade of constant spacing to hard-foam polyurethane composite crosslinking
Polyethylene board is cut, and after quality inspection, required finished product hard-foam polyurethane compound crosslinked polyethylene pad can be obtained.
Preferably, after the completion of cutting, separation stack can be carried out to hard-foam polyurethane compound crosslinked polyethylene pad with manipulator
It puts, greatly improves the efficiency.
Preferably, step (1) and the temperature of step (2) the hot melt operation are 120-160 DEG C, and at this temperature, crosslinking is poly-
Ethylene coiled material has enough viscosity and will not superfuse and deform.
It is further preferred that step (1) and step (2) hot melt use infrared fusion, can be generated heat using resistance wire
It carries out infrared emanation to be heated, proper temperature is less to the destruction of crosslinked polyethylene coiled material.
Preferably, when step (3) cutting operation, for the blade thickness used for 1mm, blade compared with the prior art is thinner,
The dust generated when cutting is less, improves the environment in workshop.
Preferably, the modified glass-fiber cloth the preparation method is as follows:
A: glass fibre is embathed with acetone soln, and drying obtains dry glass fiber；
B: dry glass fiber being placed in alkaline solution and is pre-processed, and obtains pretreated glass fiber；
C: pretreated glass fiber is placed in earth solution, and coupling agent is added, and is reacted 24-30h, is obtained modified glass-fiber,
It weaves to obtain modified glass-fiber cloth through wire drawing.
Glass fibre is that the binding ability of inorganic material and polythene material is weaker, and the present invention changes glass fibre
Property processing after re-lay and improve the binding ability at interface on polyethylene coiled material surface so that the compound friendship of finished product hard-foam polyurethane
Join the mechanical property more good stable of polyethylene pads.Glass fibre is impregnated using acetone soln first, to its surface into
Row pretreatment, cleans the impurity of surface adhesion, then glass fibre is placed in alkaline solution and performs etching processing, in glass
The surface manufacture micropore of fiber simultaneously forms the chemical bond for largely playing anchorage effect, places into earth solution and is modified place
Reason, rare earth element enter micro-porous adsorption on the surface of glass fibre, presence that can be more stable for a long time under the action of chemical bond, even
Join agent can inorganic filler with fiberglass surfacing or silanol groups form covalent bond, promote the interfacial adhesion energy of glass fibre
Power promotes earth solution to the modifying function of fiberglass surfacing.Modified treated glass fabric surface forms and has
The distortion area of rare earth element, improves the binding force with organic board.
Preferably, the length of glass fibre described in step A is 5-10mm, the covering that shorter glass fibre can be finer and close
It is stronger to the support load effect of pressure on polythene material surface.
Preferably, glass fibre described in step A uses alkali-free glass fibre, and alkali-free glass fibre is with respect to medium-alkali glass fibre
It is more preferable to the reinforcing effect of polythene material.
Preferably, the crosslinked polyethylene coiled material is manufactured by modified polyvinyl resin, the modified polyvinyl resin
The preparation method is as follows:
S1: being radiation source with ultraviolet light, in the environment of ozone, is irradiated 15-25s to polyvinyl resin；
S2: high-speed mixer is added in the processed polyvinyl resin mixing acrylamide of S1 together, obtains hybrid resin；Poly- second
The mass ratio of olefine resin and acrylamide is 5 ~ 6:1.
S3: being put into extruser for hybrid resin and squeeze out, and temperature is 160-190 DEG C, revolving speed 250-400rpm, cooling
It is granulated, obtains modified polyvinyl resin.
Polyethylene belongs to difficult viscous material, and in composite plate production, hot melting cohesion effect is unstable, and therefore, the present invention uses
The polyethylene resin feedstock that was modified prepares polyethylene coiled material.Under ozone environment, ultraviolet light irradiated polyethylene tree is utilized
Rouge surface, brings it about chemical change, increases substantially the caking property of polyvinyl resin, meanwhile, under ozone environment, the short time
Ultraviolet light irradiation will not influence polyvinyl resin ageing properties；Acrylamide, extruding pelletization are mixed into polyvinyl resin again
After obtain the higher modified polyvinyl resin of viscosity, and mechanical property is substantially unaffected.
Preferably, step (1) of the present invention uses a kind of glass fibre installation apparatus, including is located in a transmission horizontal plane
Rise gas axis a and pressure roller group, be equipped with infrared radiation heating above the delivery track that rises between gas axis a and pressure roller group
The top of device, the gas axis a that rises is equipped with the gas axis b that rises.Crosslinked polyethylene coiled material is conveyed on gas axis a rising, infrared radiation heater
Crosslinked polyethylene coiled material upper surface is heated, the modified glass-fiber coiled material to rise on gas axis b is erected at and upper surface heats
Crosslinked polyethylene coiled material afterwards is bonded at pressure roller group, under the action of pressure roller group, is bonded to glass fiber and polyethylene coiled material, behaviour
Facilitate, is laid with uniform.
The present invention has the advantages that
(1) present invention prepares hard-foam polyurethane compound crosslinked polyethylene pad using integrated assembly line, is entangled by repeatedly calibrating
Partially, the waste of material, greatly reduces cost when reducing cutting edge, and finally only with primary cutting, the dust for reducing workshop is dirty
