Summary of the invention
The present invention be directed to the shortcomings of the prior art, provide a kind of preparation of high-strength hot-dip zinc-coated fire prevention steel composite board Method, this method is easy to operate, and plastics composite plate impact resistance obtained is excellent, and thermal insulation property is good, and mechanical property is good, meets Actual operation requirements.
To solve the above problems, the technical solution used in the present invention is as follows:
A kind of preparation method of high-strength hot-dip zinc-coated fire prevention steel composite board, manufacturing method include the following steps:
Step (1), material selection: it selects with a thickness of 0.28-1.2mm, the hot-galvanized steel plate that width is 800-1200mm；
Step (2), plate face pretreatment: hot-galvanized steel plate plate face is clean, without painting oil processing is handled using plate face Agent HAS656 passivator carries out coating processing, the single side coating speed of plate face inorganic agent are as follows: 6-12m/ to hot-galvanized steel plate Min, the single side coated weight of plate face inorganic agent are as follows: 0.6-1.2g/m2, plate face inorganic agent temperature when coating are as follows: 12-24 DEG C；
Step (3), drying and processing: the hot-galvanized steel plate after coated plate face inorganic agent, which enters baking oven, to carry out at drying Reason, oven temperature are as follows: 60-70 DEG C, drying time are as follows: 10-16 seconds；
Step (4), adhesive coating: the hot-galvanized steel plate after plate face pretreatment drying enters adhesive coating journey Copoly type water solubility is synthesized emulsification liquid glue and is coated on hot-galvanized steel plate after pretreatment by sequence, and copoly type water solubility is closed At the coating speed of emulsification liquid glue are as follows: 8-12m/min, one side coating amount are as follows: 60-100g/m2, the synthesis emulsification of copoly type water solubility The temperature of liquid glue are as follows: 15-25 DEG C；
Step (5), the preparation of transition zone raw material: aluminium hydrate powder, mica powder and thermosetting phenol-formaldehyde resin powder are mixed, wherein Each material mass ratio shared in the upper epidermis raw material is respectively as follows: aluminium hydrate powder 70~90%, mica powder 2~20%, Thermosetting phenol-formaldehyde resin powder 6~8% uniformly mats formation mixed upper epidermis material into above-mentioned hot-galvanized steel by cloth system Plate surface, in the upper epidermis one layer of wheat cangue paper of material bed paving struck off or thin brown paper, jolt ramming removes bubble；
Step (6), drying program: by step (5) treated, hot-galvanized steel plate enters drying oven that journey is dried Sequence dries adhesive, allows transition zone raw material to be combined as a whole by adhesive and hot-galvanized steel plate, kiln temperatures Are as follows: 120~150 DEG C, drying time are as follows: 1.5-3.5min；
Step (7), hot pressing: by a pair of of active rubber roll of hot-press arrangement, passive steel rider to hot-galvanized steel plate surface Coat carries out hot-pressing processing, reaches hot-galvanized steel plate coat combined strength bination, hot pressing speed are as follows: 8-12m/min, pressure Are as follows: 2.5MPa-3.5MPa；
Step (8) checks storage: after hot pressing program, is checked according to standard hot-galvanized steel plate, passed examination produces Product are simultaneously put in storage.
Compared with prior art, implementation result of the invention is as follows by the present invention:
Since heat zinc coating plate surface is covered with polyvinyl chloride (PVC) film, hot-galvanized steel composite board has long service life, ring Guarantor, fire prevention, anti-condensation, corrosion-resistant, sound-absorbing, extinction, heat preservation, the high grade of transparency, high gloss, the ultraviolet light resistance that mist degree is low, excellent Separating performance, radium-shine laser anti-counterfeit performance, beautiful decorative effect.
In addition, plastics composite plate produced by the present invention includes foamed alumina layer and transition zone (i.e. fireprotection layer), transition zone In rationally adjust the amount ratio of aluminium hydrate powder, mica powder and thermosetting phenol-formaldehyde resin powder and the process conditions of subsequent forming, Each layer is combined together well, plastics composite plate obtained has excellent impact resistance, and each layer porosity is big, Wear and shock-resistant performance is splendid.
Compared with prior art, the present invention has the advantage that
(1) Corrosion Protection is strong, good corrosion resistance, and polyvinyl chloride (PVC) film plays the protective effect of one layer of covering, i.e., Make coat surface scratching that will not influence its normal corrosion resistance, makes plastics composite plate effectively antirust, service life It is long.
(2) there is good clod wash deep-draw processing forming, traditional plastic-aluminum plate and timber structure are replaced with steel plate, it is firm Durable, light-weight, convenient transportation can efficiently construct, energy saving.
(3) beautiful dicoration and wider Application Range, suitable for covering various colors and compound a variety of protection membrane structures, It can reach simulated decorative effect.
(4) smooth coating film surface dirt and spot are difficult to adhere to, and film surface easily cleans.
(5) there are superpower anti-ultraviolet function and radium-shine laser antiforge function.
