Description
Technical field
The present invention relates to a kind of plastic cement list and be coated with painted UV radiation curable coating and production thereof, using method, belong to technical field of chemical paint.
Background technology
Polystyrene, being called for short PS, is a kind of water white thermoplastics.General formula is [(CH2CHC6H5) n].There is the glass transition temp higher than 100 DEG C, be therefore often used to make the various one-trip container needing to bear water temperature.Ordinary polystyrene resin is nontoxic, odorless, colourless transparent grain, like glassy hard brittle material, its goods have high transparency, and transmittance can reach more than 90%, and have that electrical insulation capability is good, easy coloring, processing fluidity are good, good rigidly and the advantage such as chemical resistance is good.
ABS is vinyl cyanide, divinyl and cinnamic terpolymer, and A represents vinyl cyanide, and B represents divinyl, and S represents vinylbenzene, is that current production rate is maximum, most widely used polymkeric substance.ABS resin is one of five large synthetic resins, its shock resistance, thermotolerance, lower temperature resistance, chemical proofing and excellent electrical properties, also there is the features such as easy processing, product size is stable, surface luster property is good, easy application, painted, surface metallization, plating, welding, hot pressing and the secondary processing such as bonding can also be carried out, being widely used in the industrial circles such as machinery, automobile, electronic apparatus, instrument, weaving and building, is the thermoplastic engineering plastic that a kind of purposes is extremely wide.
High impact polystyrene (HIPS) is the shock proof polystyrene products of one that the way by adding poly-isoprene-isobutylene rubber particle is in polystyrene produced.This polystyrene products can be added micron order rubber grain and by the way of scion grafting, polystyrene and rubber grain be linked together.When being subject to impacting, the point stresses of crack propagation can be discharged by the rubber grain of flexible relative.Therefore the expansion of crackle is hindered, and shock resistance is improved.
In coating production process, colo(u)rant dispersion is a very main production link, and it is directly connected to the storage of coating, construction, the performance etc. of outward appearance and paint film, so reasonably select dispersion agent to be exactly a very important production link.But the quality of coating paste dispersion not only has relation with dispersion agent, and the formulation of formulation for coating material and the selection of raw material have relation.Dispersion agent turns round and look at name and conceives, and exactly various powder is reasonably disperseed in a solvent, by certain electrical charge rejection principle or polymer steric effect, various solid is very stably suspended in solvent (or dispersion liquid).
Due to features such as processability are good, outward appearance is beautiful, comprehensive mechanical property is excellent, PS has dominated electrical-appliance plastic shell market with both the ABS come by its modification.For cost consideration, PS is easier than ABS to be accepted by producer, but simple PS because of its fragility greatly, the easy shortcoming such as cracked, poor heat resistance, application is restricted.Obtain HIPS by rubber polymer modified polystyrene, i.e. high impact polystyrene, be able to widespread use owing to solving above-mentioned shortcoming at appliance shell, and instead of ABS more and more, this material is mainly applied to housing of TV set.
Photo-cured coating is also known as photoactive coating, take UV-light as the paint solidification energy, also known as ultraviolet-curing paint, do not need heating, can on the inflammable grounds such as paper, plastics, leather and timber rapid solidification film forming, primarily of photosensitive resin, photosensitizers (light trigger) and thinner composition, add some additives simultaneously, as thermo-stabilizer, when preparing colored paint, add pigment and filler.Traditional paint solidification normally passes through the solvent in the method removing macromolecular solution of heating and physical dryness, obtains the paint film hardened.UV solidification be then utilize the energy of UV-light cause low molecule performed polymer in coating or oligomer and as reactive thinner monomer molecule between polymerization and crosslinking reaction, obtaining the paint film that hardens, is in fact realize chemical seasoning by forming chemical bond.The coating material solidified advantage of UV: save the energy, capacity usage ratio is high; Solvent-free discharge, safety non-pollution; Curing speed is fast, and production efficiency is high; Can application to heat sensitive base material, film quality is high, coating performance is excellent.
Compared with traditional coating, photo-cured coating all has larger superiority in physical and chemical performance and decorate properties, and especially production efficiency significantly improves, and has now been widely used in the large-scale workpiece such as colour TV, air-conditioning ready coating.But because most polymeric resin is to PS, HIPS poor adhesive force, PS class plastics are to reasons such as solvent-susceptible, and the current generation, one deck single component tradition priming paint first made in most of producer, then covered UV gloss oil.Ye You producer attempts developing the UV coating be painted on material, but be a large problem to the sticking power of material, also to consider the impact of additive color on system drying property and appearance of film simultaneously, and each producer of HIPS plastic base material of Chinese market due to the reasons such as filler also different, therefore current on HIPS direct UV spraying still have suitable difficulty.
