5) it is dried: using naturally dry and drying two ways.
Beneficial effects of the present invention:
1, hydrotalcite and modified flame-retardant agent be joined in the present invention, modified flame-retardant agent is by nano-aluminum hydroxide and encapsulated red phosphorus Composition, when aluminium hydroxide reaches certain dosage, water supply effect sufficiently, makes hydrogenated products rapid aquation of the red phosphorus in burning at phosphorus Acid, phosphoric acid condensation generate the glassy covering of poly-metaphosphoric acid, have given full play to the fire retardation of red phosphorus;The generation of poly-metaphosphoric acid, In addition the presence of aluminium hydroxide forms charring layer when promoting burning;This charring layer can both stop heat and oxygen to enter, again The small molecule imflammable gas that pyrolysis can be stopped to generate enters gas phase, and the mixed phosphoric acid that generates of encapsulated red phosphorus and steel surface Iron rust ingredient generate Chinese blister beetle close object be covered in metal watch and, form protective film, and play the role of band rust derusting anti-corrosive;The resistance of hydrotalcite Combustion property is substantially better than aluminium hydroxide and magnesium hydroxide, and is a kind of really efficient, nontoxic, low cigarette, height the advantages of both have both The excellent environmental protection fire retarding agent of cost performance, and act synergistically with modified flame-retardant agent, further increase flame retardant effect, and ring It protects, nontoxic, good flame resistance;
2, the present invention selects the filler of calcium carbonate, talcum powder as coating;Calcium carbonate is a kind of alkaline filler, can reduce painting The blistering of layer and cracking phenomena, improve the adhesive force and mildew resistance of coating: talcum powder is a kind of hydroxo complex, existing for water In the case of ,-OH effect is very strong, and since the adhesive force of coating can be improved in the effect of hydroxyl, and make coating that there is certain thixotropic transformation, Talcum powder is configured as featheriness simultaneously, facilitates the mechanical strength for enhancing coating;
3, it since solid epoxy prepares epoxy emulsion needs that organic cosolvent is added, to ensure to develop the VOC of coating Content meets index request, and low molecular weight liquid bisphenol A type epoxy resin E-44, E-51 has been selected to mix in 4:6 ratio, and preparation is not Aqueous epoxy emulsion containing organic cosolvent.Exclusive use E-44 prepares epoxy emulsion and needs that cosolvent is added, and will cause VOC and contains Measure exceeded: exclusive use E-51 prepares epoxy emulsion and does not need that cosolvent, but poor in flexibility is added.Waterborne epoxy coatings is with water Instead of organic solvent, V0C is safe and non-toxic containing minimum, solve the gaseous volatilization bring labour protection of coating application Poisoning and Problem of environmental pollution has prevented the danger of fire, easy for construction, has unique advantage in the application of inner cabin of ship;
4, various raw materials are added by loading hopper, rotating electric machine drives threaded rod rotation, crushes to raw material, so Enter in stirred box body afterwards, driving motor drives stirring rod rotation, and stirring rod drives inclined plate and riser rotation, so that material mixes It is more uniform, solenoid valve is opened simultaneously, air compressor is to air is added in stirred box body, so that mixed material rolls, into one Step is so that material mixing is more uniform;Then it is discharged by drainage conduit, reaches in filter pipe, matched first by baffle and spring It closes and uses, buffered, reduce the impact force of material decline, avoid having damaged strainer, strainer after material filtering to can be obtained Coating;Strainer is inserted into arc-shaped slide rail, and convenient for opening chamber door, strainer is extracted, easy to replace and maintain.
