Abstract
The invention discloses a paint leveling agent which comprises the following components in parts by weight: 5-10 parts of butyl acrylate, 3-9 parts of polyether modified polysiloxane, 2-7 parts of tetrasodium pyrophosphate, 3-7 parts of sodium chloride, 4-9 parts of bamboo powder, 2-7 parts of low-temperature-curing polyester resin, 3-9 parts of epoxy resin and 5-10 parts of carbon black. The leveling agent has favorable leveling property and decorating property, accelerates and balances the volatilization of the solvent, can enhance the shining effect of the paint, can reduce the dust adsorption in the paint production process, enhances the release capacity of the coating solvent, inhibits the inter-coating dissolution action, prevents the paint from yellowing, and enhances the leveling property and hand feeling.
Description
Technical field
The invention belongs to chemical field, what be specifically related to is a kind of coating levelling agent.
Background technology
Powder coating and application with its resource-saving, economize energy, nuisanceless, labor productivity is high and be convenient to realize the features such as automation paint, become and develop one of coating variety rapidly at present.Become now generally acknowledged and met high, the excellent film performance of production efficiency, ecological environment-friendly type and Eco-power 4E type coating products.
In thermosetting powder coating(s), flow agent is one of requisite auxiliary agent in powder coating composition.No matter be Gao Guang, have light, half light, sub-light or glossless powdered coating, in powder coating formulation, all must add flow agent.Compared with liquid coating, the levelling of powder coating is more much more difficult than liquid coating, and the levelling property of powder coating film is also far short of what is expected than liquid coating film, and this and powder coating do not have much relations containing solvent.The film process of powder coating relies on the flowing of resin under molten state and inter-adhesively to form, and melt viscosity is high, limits its unrestricted flow, and levelling effect is slightly poor, has slight orange peel to produce.Improve powder coating film levelling property, form the film that outward appearance is good, be the emphasis that powder coating circle is paid close attention to always.
Powder coating is generally the levelling property improving powder coating by adding flow agent, by balancing the surface tension gradient of film, alleviating Bei Nade eddy effect, alleviating orange peel, promotes that film has better levelling property.But the interpolation of too much flow agent can affect the package stability of powder coating.
The flow agent that powder coating is conventional has Voncoat R 3310, acrylate copolymer, silicone modified polyacrylate and polyoxy silane etc., these flow agents are all generally thick liquid, also need in use to be distributed in resin, aerosil or some filler, this will increase cost to suitability for industrialized production.Flow agent used for powder coating research is at home also fewer, and in order to obtain the film of different planeness, the research of flow agent used for powder coating will be an important directions.
In prior art, the current domestic level of flow agent used for powder coating is lower, and film flow leveling does not reach expection requirement, and flow agent range of application is restricted, and coating film gloss degree does not reach related request; Great majority are viscous liquid, are inconvenient to add use; Flow agent system is different, and consistency is bad, easily mutually produces interference.
Summary of the invention
The object of the invention is to overcome the above problem that prior art exists, provide a kind of coating levelling agent, levelling, nonshrink hole, enhanced shine are good.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of coating levelling agent, comprises following component in components by weight percent: butyl acrylate 5-10 part, Siloxane-Oxyalkylene Copolymers 3-9 part, tetrasodium pyrophosphate 2-7 part, sodium-chlor 3-7 part, bamboo powder 4-9 part, low temperature curing polyester resin 2-7 part, epoxy resin 3-9 part, carbon black 5-10 part.
Preferably, comprise following component in components by weight percent: butyl acrylate 6-8 part, Siloxane-Oxyalkylene Copolymers 4-6 part, tetrasodium pyrophosphate 3-5 part, sodium-chlor 4-6 part, bamboo powder 5-8 part, low temperature curing polyester resin 3-5 part, epoxy resin 5-7 part, carbon black 6-9 part.
The invention has the beneficial effects as follows:
Flow agent of the present invention has good levelling property and decorate properties, accelerate and the volatilization of balanced solvent, the flash effect of coating can be strengthened simultaneously, the absorption to dust in coating production process can be reduced, improve the releasability of coating solvents, accelerate and the volatilization of balanced solvent, suppress the solvency action being coated with interlayer, make coating not easily xanthochromia, promote levelling and feel.
