Principle of the present invention is:
Described encapsulant is the organic inorganic hybridization dispersion liquid, and the invention by following record realizes:
This encapsulant membrane formation mechanism:
(1) in medicament, add normal low-temperature bake type polymer waterborne resin, behind overbaking, the water-base resin volatilization, the TiO2 that forms continuous densification in the metallic surface intercepts epithelium, and resin emulsion plays bridging action between the TiO2 particulate, and fixing TiO2 has improved the water tolerance of film.As shown in Figure 1.
The silane coupling agent that adds in medicament on the other hand has different chemical functional group, through hydrolysis, polycondensation, dehydration reaction, generate covalent linkage in one end and functional group and the macromolecule resin, an end becomes covalent linkage ≡ Si-OH+HO-Me → ≡ Si-O-Me+H with the hydroxyl reaction on inorganic metal surface
2O combines the very big material of nature difference, has improved the water tolerance and the secondary application sticking power of film.As shown in Figure 2.
(2) this encapsulant principal character: contain A, a kind of water-soluble fluorine carbon resin, B, the two pawl silane coupling agents of a kind of water-based, a kind of silane coupling agent with high reaction activity, C, a kind of water-soluble ultra-fine micropowder, D, a kind of dispersing and antisludging agent, E, a metal ion species intercalating agent, F, a kind of inhibiter, G, a kind of defoamer H, deionized water.The PH of masking liquid is 7～9.
1. above-mentioned (1) described a kind of water-soluble fluorine carbon resin, preferably water dissolubility poly-hydroxy fluorocarbon resin, reason is: the bond energy of fluorine carbon bond is maximum in the organic compound, so the corrosion prevention film based on fluorine carbon has good physical and chemical stability, have characteristics such as chemically stable that other resin can't replace, resistant, heatproof, perviousness, UV resistant.Under the effect of good penetration, become continuous dead front type coating in the coil surface adhesion, understand of the erosion of environmental corrosion media such as effective block water molecule, O2 molecule, thereby show good anticorrosion ability metal under the film.And various countries are to the increasingly stringent of VOC content restriction, and the water-based fluorocarbon resin does not contain VOC, environment friendly and pollution-free.And the contriver considers the construction and the membrane formation mechanism of whole formula system, with the molecular chain action of other organic or inorganic storerooms, poly-hydroxy water-based fluorocarbon resin can provide more hydroxyl, and form better molecule bonding force between other inorganic or organic coupling agents, can improve sticking power greatly.
2. the two pawl silane coupling agents of above-mentioned (1) described a kind of water-based, preferred BTMSE, promptly 1, the two (trimethoxies of 2-
3. a kind of high reaction activity silane, preferred water-based aminosilane, i.e. γ-An Bingjisanjiayangjiguiwan.More preferably from the A-1100 of U.S.'s union carbide corporation.
General silane has shown remarkable effect at inorganic material surfaces such as tripoli, but when at the metallized metal substrate surface, is that effect or glutinous sticking trend all reduce greatly.And two pawl silane have two hydrolysising groups, can improve greatly with inorganic metal surface hydroxyl covalent linkage and form density, improve the glutinous viscosity with inorganic materials.And the water-based aminosilane, amino organic group has high reaction activity and high, and easy and organic polymer resin forms lasting firm chemical bond fast.So add a spot of pair of pawl silane in the water-based aminosilane, the two is combined in can erect the molecule bridge of strong, durable more between organic resin and the inorganic metal base material.
4. above-mentioned (1) described a kind of ultra-fine micropowder.Preferred nano titanium oxide.Titanium dioxide has excellent chemical stability, thermostability, nontoxicity nanometer, and TiO2 has very strong " Superhydrophilic ", is difficult for forming the globule on its surface, has to intercept water tolerance preferably.
5. above-mentioned (1) described a kind of dirt dispersion agent.Preferably water dissolubility sodium lignosulfonate.Sodium lignosulfonate is a kind of natural polymers, has very strong dispersiveness, because
Molecular weightWith
Functional groupDifference and have in various degree dispersiveness, it is a kind of surfactant, can be adsorbed on the surface of various solid particles, can carry out the metal ion exchanged effect, also because have various active groups on its weave construction, thereby can produce condensation or with other compound generation hydrogen bond actions, have scale inhibition and dispersion preferably.
6. above-mentioned (1) described a kind of metal ion chelation agent.Preferred Citric acid monohydrate Food grade.Citric acid monohydrate Food grade has the ability of iron, calcium, magnesium ion in the stronger huge legendary turtle Heshui, and with low cost, environment-protecting asepsis.
7. above-mentioned (1) described a kind of inhibiter.Preferred inorganic inhibitor Sodium Tetraborate.Sodium Tetraborate has strong corrosion inhibition to carbon steel and zinc-plated material in neutrality or weakly alkaline solution system, and to human body and environmentally friendly, and with low cost.
8. above-mentioned (1) described a kind of defoamer.Preferred silicone antifoam agent.Silicone antifoam agent has under the less situation of consumption, but has outstanding antifoam performance, and heat-resisting, cold-resistant, weather-proof and ageing-resistant performance is given prominence to, and nontoxic, pollution-free, and so environmental sound is preferred.
9. above-mentioned (1) described a kind of deionized water.Preferred deionized water specific conductivity≤10 μ S/cm.Because this encapsulant mainly designs on automatic production line and uses, the cleanliness factor of having relatively high expectations, and satisfy the requirement for anticorrosion of the coiled material of very fast streamline (100m/min), so the inventor is through experiment, find that selected encapsulant carrier institute water need select deionized water for use, and specific conductivity palpus≤10 μ S/cm.
Beneficial effect of the present invention is: though encapsulant of the present invention does not contain chromium, phosphorus etc. to the environment harmful ion, but the three-dimensional netted molecular bonding structure that can produce on coiled materials such as cold rolling, zinc-plated, aluminum-zinc alloy surface makes that sealing rete ratio contains chromic salt, phosphatic sealing rete has more solidity to corrosion, weathering resistance, coating, electroconductibility.Rare resin liquid and the two pawl silane coupling agent BTMSE of water-based, water-based aminosilane are reacted, resin have been carried out modification,
Increased the film forming properties of resin.
