Description

A kind of ultraviolet optical coating and its preparation method with anti-mildew performance
Technical field
The invention belongs to chemical material technical fields, specifically, being related to a kind of ultraviolet light painting with anti-mildew performance Material and its preparation method.
Background technology
Cooktop surface generally uses stainless steel plate, but stainless steel is of high cost, weight is big and is not easy cleaning-nursing, later Large area replaces stainless steel plate using glass.Glass is a kind of relatively transparent non crystallized silicates nonmetallic materials, The transparency and certain intensity, hardness, surface smoothness with light can compare favourably with mechanical polishing.Glass extensive use In fields such as building, automobiles, have become a kind of basic means of production.Glass is the non-conductor of heat, and has fragility.When When temperature difference inside and outside glass is too big, cause inside glass stress is inconsistent will cause glass since expansion rate is different Cracking.Solve glass causes cracking glasses to be highly desirable due to uneven heating.Graphene is that known world is most thin, most hard Hard nano material, single-layer graphene are almost fully transparent, only absorb 2.3% light, while the thermal coefficient of graphene is high It is more taller than diamond up to 5300W/mK.
But prior art shortage is preferably applied graphene in burner glass surface to solve the equal heat problem of glass Coating.
Ultraviolet-curing paint is a kind of new coating, in the coating photoinitiator after ultraviolet light, generate from By base or ionic group, cause chemical anti-to cause the unsaturated double-bond of ultraviolet curable resin and active monomer diluent It answers, realizes the solidification of coating.Compared with heat curing coating, ultraviolet-curing paint does not generate volatile organic matter in solidification process Pollution, avoids in traditional coating solidification process and its serious exhaust emission, meanwhile, in ultraviolet-curing paint solidification process Without heating, the energy expenditure of paint solidification process is saved, energy consumption is only the 1/5 of heat cure, the paint film layer tool of formation There is the features such as wear-resisting, hardness is high, corrosion-resistant.This kind of coating is widely used to woodenware, plastic casing, fibre coating, doctor at present The external coating in instrument and automobile industry is treated, market prospects are boundless.
Although ultraviolet-curing paint has above-mentioned many advantages, in many application fields, ultraviolet-curing paint Film performance has a certain distance compared with traditional heat curing coating, wherein critically important one the reason is that ultraviolet light solidification apply Material shrinking percentage in flash cure process is high, and it is poor to result in adhesive force.Especially PET sheet packaging material field, to table The performance requirements such as finishing coat film hardness, the transparency and scratch-resistant are higher and higher, however, ultraviolet-curing paint is due to stronger Convergent force results in adhesive force and is greatly reduced, and PET sheet brittleness is increased.Therefore, ultraviolet-curing paint is reduced Shrinkage stress has a large amount of research and report.Chinese patent literature 201110189918.1 discloses a kind of alicyclic epoxy third Olefin(e) acid ester prepolymer is to improve the shrinkage stress during paint solidification, but the prepolymer is by cycloaliphatic epoxy resin and propylene Acid or methacrylic acid directly react, and the prepolymer molecular weight is smaller, and film is more crisp.Chinese patent literature 201410212211.1 disclosing a kind of alicyclic epoxy urethane acrylate ultraviolet-curing paint of modification, the coating Chemical composition include modified alicyclic epoxy polyurethane acrylate prepolymer, active monomer diluent, photoinitiator, stream Flat agent, adhesion promoter, the invention coating is small with curing system shrinking percentage, shock resistance is strong, cured film flexibility is good, The features such as adhesive force is high.Above-mentioned this two patents reduce the contraction of paint film, improve adhesive force, so obtained from coating hardness It is relatively low, it especially in PET sheet after application, will produce in use " mildew ".Chinese patent literature 201120306544.2 disclose a kind of UV coating structures of Wear-resistant scratch-resistant flower, including are applied in epoxy zinc rich primer layer, polyurethane Layer and urethane acrylate top coat layer add abrasion-resistant powder in top coat layer, to improve the hardness and wearability of coating.It is Chinese special Sharp document 201410075434.8 discloses a kind of safety and environmental protection wear-resistant ultraviolet ray solidified paint, by polyester acrylate, 1,6- Hexanediyl ester, methoxy polyethylene glycol methacrylate-styrene polymer, photoinitiator, double pentaerythritol methacrylate, vinegar Acid butyl ester, polymethylphenylsiloxane, antioxidant, nano-bentonite, nano bamboo carbon powder, IPBC and auxiliary agent are constituted.The invention Nano-bentonite, nano bamboo carbon powder are added, good dispersion increases mobility, and nano bamboo carbon powder has good electromagnetism Shielding action, and anion and far infrared can be discharged, it is safe to the human body harmless;Add auxiliary agent, good leveling property, film adhesive Good, hardness is big, wear-resisting, energy conservation and environmental protection.This two patents are although improve the hardness and wearability of paint film, due to powder Addition, reduce the light transmittance of paint film, cannot be satisfied coating for PET sheet and use.That is, up to the present, Wear-resisting scratch-resistant ultraviolet-curing paint is prepared, the UV-cured resin of high functionality is typically used, and is added a small amount of Abrasion-resistant powder, smooth powder or polyethylene wax improve scratch-resistant performance and wearability, however, with the addition of these fillers, Result in the decline of the paint film transparency.If the PET sheet do not added filler, and can made generates a large amount of " mildew ", make its appearance It is greatly reduced.
Thus, the ultraviolet-curing paint with anti-mildew function of high transparency has become PET sheet industry application The very important coating of one kind.
