Description
Technical field
The invention belongs to art of powder coatings, relate to a kind of super-weathering resistance powder coating.
Background technology
Nearly ten years, along with improving constantly of the growing of national economy and living standards of the people, more and more higher to ornamental, weathering resistance, chemical-resistant, water tolerance and polluting proofing property the requirement of coating.
Common F-C paint has excellent weather resisteant, chemical resistance.Such as commodity are called the F-C paint of PVDF, be admittedly containing 40% solvent based coating, out, there is not altered chemical structure in solidification process in the solvent up to 60% and Volatile organic emissions, needs to improve sticking power to ground with epoxy primer.Require 3 ~ 4 road coatings, priming paint is protective paint colored paint, and needs Lacquer finish finish paint.Due to priming paint not UV resistant, can not alone transparent effect, efflorescence can be made it in the effect of UV-light, peel off.In process control procedure, need high bake equipment, solidify insufficient, can paint film defect be caused.And gloss can only control between 20-35%.
Powder coating is except the performances such as excellent weather resisteant and chemical resistance, and technology controlling and process is simple, use and boundary of works area extensive.But weather-resistance powder coatings of the prior art, all with weather resistant carboxy(l)polyester or based on weather resistant hydroxyl polyester, also cannot meet the higher requirement of client in endurance quality.
(the Huang Zhixiang such as Gong Yongzhong, Gong Yongzhong, modern coatings and application, 2006(5) and Gong Yongzhong, China's coating, 2005(8)) describe the performance and application field of thermosetting fluoro carbon resin and thermosetting fluorocarbon powder coatings, show that thermosetting fluorocarbon powder coatings neutral salt spray test 2000 hours is unchanged; Accelerated weathering test 5000 hours, it protects light rate is 92-98%, and weather resistance is expected to reach more than 30 years.
Shi Qiwu is at weather resistant polyester powder coating progress (Shi Qiwu, engineering plastics are applied, point out 2008(3)), domestic and international polyester powder coating is being selected to resins synthesis and modification, curing system, solidifying agent and the developing direction such as special auxiliary agent interpolation at present, the weathering resistance of performance to powder coating of polyester and solidifying agent plays vital effect, effectively can improve weathering resistance with the powder coating that nanometer particle-modified resin-made is standby simultaneously.
Kurt Wood etc. points out in fluorocarbon polymer coating exterior wall weather resistance article (Journal of Fluorine Chemistry 2000 (104)): in formula reasonable in design, the content of fluorine superpolymer is 80-95%(weight ratio), the content of weather resistance acrylic resin is 5-20%(weight ratio) the exterior wall endurance quality of fluorine resin coating best.Select urethane as crosslinking curing, the sticking power of paint film obviously can.
Shiow Chin etc. (U.S.Patent 6812267,2004) prepare the powder coating preparation technology containing methyl methacrylate polymer and fluoropolymer, point out that composite is thermoplasticity PVDF fluoropolymer, not composite thermosetting fluoro carbon resin.
Can find from above document, the base-material selected by super weather-resistant powder paint mentioned is respectively weather resistant polyester, thermosetting fluoro carbon resin, acrylic resin and thermoplasticity PVDF fluoropolymer, the scope of application and selectivity narrow.Weather resistant polyester powder weather resistance does not reach F-C paint effect; And pure fluorocarbon powder paint is expensive, technique controlling difficulty is high; Composite is thermoplasticity PVDF fluoropolymer, and unstable properties, Oil repellent is on the low side.
Involved in the present invention to the super weather-resistant powder paint that can replace fluorocarbon oil paint, be different from now based on thermosetting fluoro carbon resin or the powder coating of acrylic acid modified fluorocarbon resin and the super weather-resistant powder paint containing polyvinylidene difluoride (PVDF) PVDF.Involved in the present invention to replacement fluorocarbon oil paint surpass weather-resistant powder paint with its superpower weather-proof and chemical-resistant, good storage stability, good film physical and mechanical property, and the performance such as snappiness, sticking power and the coating performance easily of film is balanced by component proportion each in adjustment system, the super weather-resistant coating of fluorocarbon oil paint can be replaced, also can replace existing thermoset and surpass Weather-resisting powder coating.
Summary of the invention
The object of this invention is to provide a kind of super weather-resistant coatings, there is superpower weather-proof, chemical-resistant, good storage stability and film physical and mechanical property, fluorocarbon oil paint of the prior art can be replaced.
Super-weathering resistance powder coating of the present invention, this powder coating be using after composite for thermosetting fluoro carbon resin acrylic resin and hydroxy polyester resin as matrix resin, adopt cured with isocyanates make.
The preferred Hydroxylated acrylic resin of described acrylic resin, can have following two kinds of formulas, and wherein isocyanate curing agent is Blocked Isocyanate Curing Agents or inner sealing type isocyanate curing agent:
(1) with weight parts, powder coating is made up of following raw material:
(2) with weight parts, powder coating is mixed according to weight ratio 1:1 after extruding sheet stock by following component A and B component:
Component A:
B component:
The preferred carboxyl acrylic resin of described acrylic resin, can have following two kinds of formulas, and wherein isocyanate curing agent is Blocked Isocyanate Curing Agents or inner sealing type isocyanate curing agent:
(3) with weight parts, powder coating is made up of following raw material:
(4) with weight parts, powder coating is mixed according to weight ratio 1:1 after extruding sheet stock by following component A and B component:
Component A:
B component:
The powder coating that the present invention is intended to prepare can replace fluorocarbon oil paint, its after the composite acrylic resin of thermosetting fluoro carbon resin and hydroxy polyester resin as matrix resin, be solidifying agent with masked isocyanate, coordinate the manufacture super-weathering resistance powder coating such as corresponding pigment and filler.
The production process of super-weathering resistance powder coating of the present invention is as follows:
Determine that super weather-resistant powder paint formula → composite raw material → batch mixing → coextrusion → compressing tablet material → pulverizing → grinding → mistake screen sizing → super-weathering resistance powder coating product detects packaging → finished product by specific client
The coating curing process of super-weathering resistance powder coating carries out according to following common process:
Workpiece surface pre-treatment → spraying replaces fluorocarbon oil paint and surpasses weather-resistant powder paint → heat levelling → hot setting → Workpiece inspection warehouse-in.
Beneficial effect of the present invention is as follows:
The present invention is base-material by the composite acrylic resin of thermosetting fluoro carbon resin and hydroxy polyester resin, employing cured with isocyanates is made, powder coating of the present invention not only has the feature of environmental protection, super-weathering resistance, and can reuse, this powder coating price is far below the price of fluorocarbon powder paint.
Super-weathering resistance powder coating of the present invention is with the chemical resistant properties of its excellence, weathering resistance and high-decoration; can be used for the durable protective decoration industry such as shop equipment facility, car body and household electrical appliances, aluminium alloy curtain wall, television transmitting tower coating, also can be widely used in the building material field such as bridge, door and window, enclosure wall, family expenses mark look material.Super-weathering resistance powder coating of the present invention has all features of thermosetting fluoro carbon resin, and application property is strong, and weather resistance can for 25 years, and its weather resistance is better than fluorocarbon oil paint, can replace fluorocarbon oil paint.
