Description
Technical field:
The present invention relates to ambient cure fluoro-containing coating of the quarternary copolymerized method preparation of a kind of usefulness and preparation method thereof.
Background technology:
Progress along with society, improving constantly of people's living standard, people also improve gradually to the requirement of domestic environment, use historical over and done with that lime whitewashes a wall in the past, coating is that everyone decorates the necessary a kind of material of family, but some shortcomings of modern coating have also exposed thereupon, and the widespread usage trifluorochloroethylene is made coating now, the product stability of using the manufacturing of this kind method is poor, easily crystallization.So eager needs can overcome the product birth of these shortcomings on the market.
Summary of the invention:
The present invention utilizes tetrafluoro vinylchlorid to replace trifluorochloroethylene, and the strong bond energy of tetrafluoro vinylchlorid CF is higher than the bond energy of trifluorochloroethylene C-Cl, makes the multipolymer Heat stability is good, and contamination resistance and unreactiveness are higher.
Above-mentioned purpose realizes by following technical scheme:
A kind of ambient cure fluoro-containing coating of quarternary copolymerized method preparation, its composition comprises: tetrafluoro vinylchlorid, vinyl fatty ester, aliphatic olefin alcohols and fatty olefin(e) acid, it is characterized in that: the shared parts by weight of solids content are 60～70, hydroxyl value is 40～75mgkoH/g, acid number is 8～15mgkoH/g, be coated with 4 one glasss of viscosity 45～54s, proportion is 1.10～1.25, described tetrafluoro vinylchlorid, vinyl fatty ester, aliphatic olefin alcohols and fatty olefin(e) acid at the shared ratio of weight and number of polymkeric substance are: 35～45:25～40:12～18:2～3, its chain schematic construction is: R
1=C
1～C
3Normal chain alkyl; R
2=(CH)
n, n=1～6; R
3=(CH
2)
n, n=1～10.
The making method of the ambient cure fluoro-containing coating of above-mentioned quarternary copolymerized method preparation, vinyl fatty ester, aliphatics enol, aliphatics olefin(e) acid and initiator are mixed, in the autoclave of-97kPa, vacuumize, vacuumize once more behind the inflated with nitrogen, suck tetrafluoro vinylchlorid and heat to 68～72 ℃, pressurization 500kPa～800kPa, it is 50% with solvent with the solids content dilution that reaction 20h forms multipolymer, be prepared into fluorine-containing paint vehicle, this material and pigment 3:1 mixed grinding fineness 25 μ m make finished product.
The making method of the ambient cure fluoro-containing coating of above-mentioned quarternary copolymerized method preparation, it is characterized in that: described initiator is a Diisopropyl azodicarboxylate, described solvent is dimethylbenzene, butylacetate or methyl iso-butyl ketone (MIBK).
This technical scheme has following beneficial effect
1. the present invention utilizes tetrafluoro vinylchlorid to replace trifluorochloroethylene, and the strong bond energy of tetrafluoro vinylchlorid CF is higher than the bond energy of trifluorochloroethylene C-Cl, makes the multipolymer Heat stability is good, and contamination resistance and unreactiveness are higher.The multi-component copolymer typing is quarternary copolymerized for this reason, is convenient to the parameter of multipolymer, and principal monomer and other monomeric ratio gap are dwindled, and can reduce the degree of crystallinity of multipolymer, improves the homogeneity of multipolymer in solvent.
The multipolymer high solids content be 60～70%, low viscosity (be coated with 4 one glasss of viscosity 45～54s), can be fine wetting, scattered with pigment, prevent that lacquer such as loose colour is sick, the paint film property that makes is superior.
3. the product hardness height that the present invention produced, softness, good luster and strong adhesion, anti-smog, chemicals-resistant, good weatherability.
4. this product is lacked at normal temperatures set time, reaches the maximum of paint standard, has remarkable resistant and self-cleaning property, can be made into the environment-friendly type marine antifouling coating, and the exterior coating, the aircraft anti-icing that also can be made into automobile case supercoat, self-cleaning are avenged coating etc.
5. because the atomic radius of fluoropolymer is little, polarizability is little, surface tension is little, so show resistance to bond, and fluoro-resin has less internal cohesive energy and low-friction coefficient, and the base-material as wear proof lubricating painting materials is equipped with lubricant, its wear-resisting lubricity is then more outstanding, so be widely used in industries such as mould, cooker, household electrical appliances, machinery equipment.Also can be used for outdoor long-acting, high-decoration protective cover.
6. fluoro-containing coating has good weathering resistance; good guarantor's light tint retention energy is difficult for efflorescence, good luster; fluorochemical urethane coating has good moisture-proof and ultraviolet-resistant performance, is widely used in the protection of aircraft skin, car paint, large storage tank surface and stone artifact.
