Above-mentioned foam substrate is sent by conveying mechanism 10 in the cabinet 22 of sander 20, the rotating roller in cabinet 22 is by sand The driving of photoelectricity machine 231 rotates, and the sand paper rotation in rotating roller carries out sanding to foam substrate.Sanding process is：Foam substrate is first By the first rotating roller 25, there are 80 the first sand paper of purpose 251 in the first rotating roller 25, first time sand first is carried out to foam substrate Light；Foam substrate has 120 the second sand paper of purpose 261, then use 120 again by the second rotating roller 26 in second rotating roller 26 Purpose sand paper carries out second of sanding；Foam substrate has 180 purposes finally by third rotating roller 27 in the second rotating roller 27 Third sand paper 271, third sand paper 271 carry out third time sanding to foam substrate.After the completion of sanding, takes out dirt wind turbine 241 and opens, The miscellaneous dirt in sanding rear rack and foam substrate surface is evacuated to sweep-up pipe 242, is discharged by sweep-up pipe 242, more effectively in The subsequent operation of foam substrate.
Sanding and except the foam substrate after dust is delivered to windrow mechanism 30 by conveying mechanism 10, after multiple processing Foam substrate when being stacked in windrow mechanism 30, windrow mechanism 30 declines for use；When needing to start subsequent processing, windrow Mechanism 30 rises, and first piece of foam substrate is aligned with conveying mechanism 10, to send to conveying mechanism 10, thus successively by heap Folded each foam substrate is sent to conveying mechanism 10, carries out the processing of next process successively.
Foam substrate is delivered between the upper roller 41 of rubber-coated mechanism 40 and bottom roller 42 by conveying mechanism 10, upper roller 41 Resin is coated in two surfaces of foam substrate, tree with resin is poured on bottom roller 42 when upper roller 41 is with the operation of bottom roller 42 The coated weight of fat is controlled in 100g/m2-120g/m2, wait for resin automatic drying 2min-5min.It can be by controlling pouring into for resin Amount, to control coated weight of the resin on foam substrate.
After the completion of coating, last layer fireprotection layer (fire-proof plate) is respectively covered on the two sides of foam substrate using cladding plate mechanism 60, Intermediate product are formed, the size of best fire-proof plate is identical as the size of foam substrate, is conducive to the follow-up compacting of intermediate product.The process can By being accomplished manually, can also be completed by compound machine.
After the completion of compound, conveying mechanism send above-mentioned intermediate product to windrow mechanism 30, and multiple above-mentioned intermediate product are stacked on Together, 2min-30min is suppressed naturally；
Between two pressing plates 51 that intermediate product after the completion of above-mentioned compacting are delivered in cold press 50 by conveying mechanism 10, It is cold-pressed, wherein the pressure of cold press is 1.0kg/cm2-1.6kg/cm2, temperature is 35 DEG C -50 DEG C, pressing time 5h- 6h。
Intermediate product after the completion of cold pressing are transferred out cold press 50 by conveying mechanism 10, are placed in spontaneous curing at room temperature and are derived 2 It -5 days, form semi-finished product；
Using the laser cutting machine either redundance at other equipment or artificial excision semi-finished product edge, and remove surface Burr, obtain PVC foam fire prevention board finished product.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention Protect range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
