Description
Technical field
The invention belongs to auxiliary agent technical field, be particularly related to a kind of coating reinforcing aids.
Background technology
Building coating occupies very consequence in coatings industry, and along with China's building and the fast development of adnornment industry, people are to the continuous enhancing of improving constantly of requiring of quality of life and environmental consciousness, and coating industry is attaching importance to environmental protection more and more.And the coating of environment-friendly type, its weathering resistance is poor, and stability is bad, therefore, is necessary to provide a kind of coating reinforcing aids.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect mentioned and deficiency, and a kind of coating reinforcing aids is provided.
The technical scheme that the present invention realizes the employing of its object is as follows.
A kind of coating reinforcing aids, comprise: the polyoxyethylene of 25 ~ 31 weight parts, the glycidyl methacrylate of 19 ~ 27 weight parts, the dioctyl phthalate (DOP) of 5 ~ 20 weight parts, the SBS thermoplastic elastomer of 15 ~ 21 weight parts, the UPVC of 15 ~ 25 weight parts, the CPVC of 5 ~ 12 weight parts and the kaolin of 5 ~ 8 weight parts.
Described kaolinic granularity is 1.0u.
A kind of coating reinforcing aids, also comprises the solvent oil of 5 ~ 10 weight parts; Described solvent oil is the mixture of furfural extract oil or waste cooking oils and furfural extract oil.
A kind of coating reinforcing aids, also comprises the dispersion agent of 6 ~ 8 weight parts; Described dispersion agent is the modest DA-325 of moral of the amine salt of polymer polycarbonate.
A kind of coating reinforcing aids, also comprises the stablizer of 3 ~ 5 weight parts; Described stablizer is made up of three salt, disalt, mercaptans type and lead stearate; By weight, three salt: disalt: mercaptans type: lead stearate==1:1:1:1.
Described polyoxyethylene (PEO) is a kind of knot soluble polymer.Polyoxyethylene is completely water-soluble, can other materials and water be combined closely better.Polyoxyethylene can also improve the compactedness of coating, increases the suitable environment of coating.
Described glycidyl methacrylate (GMA) is colourless liquid, the existing unsaturated group that can carry out radical polymerization in molecular structure, respond again the active epoxy group(ing) extremely strong with cementability, copolymerization can be carried out with other acrylate, have better weather-proof, heat-resisting, water-fast, alkaline-resisting, heat-proof water, shock-resistance, can processing technology and snappiness.
Described dioctyl phthalate (DOP) (DOP), as softening agent, makes the planeness of coating good, and has satisfactory stability.
Described SBS thermoplastic elastomer improves the firmly crisp and hot mastication of the low temperature of coating, improves the stability of product.SBS thermoplasticity rubber is the thermoplastic elastomer of polystyrene-polybutadiene-polystyrene three block type, and it is with line style polyhutadiene for parent, and all linking polystyrene at parent two ends is the segmented copolymer of terminal segments.The second-order transition temperature of polyhutadiene parent is-85 DEG C, has good cold resistance, and the second-order transition temperature of polystyrene is 90 DEG C, has good high temperature resistance.Therefore, use the coating reinforcing aids of SBS thermoplasticity rubber, there is larger use temperature scope.In addition, the segment kindliness of polyhutadiene parent is good, makes coating reinforcing aids have good elasticity and wear resistance.The elongation at break of SBS thermoplastic elastomer is greater than 700%, improves the snappiness of coating reinforcing aids.
UPVC, rigid polyvinyl chloride is the amorphous thermoplastic resin that vinyl chloride monomer is made through polyreaction.The melt viscosity of UPVC is high, poor fluidity, even if improve injection pressure and melt temperature, the change of mobility is also little.In addition, the mold temperature of resin and heat decomposition temperature are very close, and it is very narrow to carry out shaping temperature range, are a kind ofly to be difficult to shaping material.
CPVC, chlorinated polyvinyl chloride, be the chlorination modified further product of polyvinyl chloride (PVC), its cl content is generally 65% ~ 72% (volume fraction).CPVC is except a lot of premium propertiess having PVC concurrently, its erosion resistance had, thermotolerance, solubility, flame retardant resistance, physical strength etc. are all greatly improved than PVC, thus CPVC is the type material of excellent property, is widely used in the fields such as building, chemical industry, metallurgy, shipbuilding, electrical equipment, weaving.
UPVC and CPVC, in order to ensure that auxiliary agent has good consistency, forms zone of transition between coating and SBS thermoplastic elastomer, makes the staggered bonding of coating and SBS thermoplastic elastomer phase mutual diffusion in zone of transition.UPVC and CPVC with the use of, reduce difficulty of processing, improve coating intensity and Corrosion Protection.
Kaolin, is commonly called as white clay, and its structure is Al
2o
3(SiO
2)
2h
2o, by force, good insulating, refractoriness is high for plasticity-and associativity.Its granular size, all has a significant impact its plasticity-, mud viscosity, ion exchange capacity, processability, drying property.Founding property of the technical program at the kaolin adding 1.0u granularity, in order to change auxiliary agent rheological property, make auxiliary agent have good viscosity, ensure auxiliary agent thick film construction do not produce sagging.Meanwhile, kaolin further increases the solidity to corrosion of this auxiliary agent, also has barrier effect to water medium.
Described dispersion agent effectively reduces the interfacial tension of solia particle and coating phase.Properties-correcting agent can not dissolve completely in coatings additive(s), and usually exist with more tiny particle, under hot store status, these small particles can produce sedimentation under gravity, cause the segregation of auxiliary agent.Therefore, adding of dispersion agent, in order to improve elasticity and the toughness of coating, guarantee the hot storage stability that auxiliary agent is long-term, do not emanate.
Stablizer, because resin easily decomposes in the process of processing, so need to add thermo-stabilizer in order to reach thermostable effect.In the present invention, have employed three salt (lead sulfate tribasic), disalt (dibasic lead stearate), mercaptans type and lead stearate.Mercaptans type and lead stearate have significant synergistic effect, can significantly improve the long-term thermal stability of resin, obtain best processing characteristics.
Coating reinforcing aids of the present invention comprises SBS thermoplastic elastomer, UPVC and CPVC, combines the feature of each component, maximizes favourable factors and minimizes unfavourable ones, and improves the over-all properties of auxiliary agent, has high temperature resistance, anti-low temperature, anti-slippery, cracking resistance line and life-span long feature.UPVC, CPVC and kaolinicly to add, mutual generation synergy, kaolin decomposes other ion of Al and Si ion pair produced polarized action, adds the shrinking percentage of UPVC and CPVC, improve plasticity-and the viscosity of auxiliary agent, three improves the non-corrosibility of auxiliary agent jointly.
