Description
Technical field
The present invention relates to a kind of solvent-borne type oiliness bi-component epoxide-resin paint
Background technology
Conventional oil-based paint and bi-component epoxide-resin paint does solvent (following letter using poisonous " benzene,toluene,xylene "
Claim " triphen " solvent).
The formulation properties of water paint determine can not possibly substitute oil paint completely in many field of coating.And water-based paint formula
In required emulsifying agent and coalescents such as butyl glycol ether etc composition, there is also the negative effect to the mankind and environment.
It is the leading position for accounting for application in suitable long-term solvent-borne type oil paint.The double groups of environmentally friendly solvent oiliness of the present invention
Epoxy resin paint is divided to substitute the paint containing " triphen " solvent, and the numerous areas that water paint can not be applied.In furniture system
Make application, local-style dwelling houses and hospital of school and commercial office place finishing, ship vehicle and plant equipment anti-corrosive primer, floor paint
Etc. be all suitable for.
Adjust and paint in work progress without using any " triphen " solvent, user in the technology of the present invention process of producing product
Viscosity also without using " triphen " solvent.The design of this inventive technique formula uses green dimethyl carbonate (following letter
Claim DMC), ethanol, n-butanol make solvent, fully and completely substitute the solvent that " triphen " solvent makees bi-component epoxide-resin paint, from
Thoroughly prevent the harm come using " triphen " solvent bank on source.
Dimethyl carbonate, ethanol, n-butanol are to accept relatively green solvent in the world.Dimethyl carbonate manufactured
Journey is raw material using carbon dioxide；Ethanol and n-butanol use leftover bits and pieces bagasse and molasses or corn and potato mostly both at home and abroad
Amylo process produces.The bi-component epoxide-resin that " triphen " solvent is substituted using this three sections of solvents is painted to human health and ring
Border is protected and the sustainable Commercial cultivation of resource has significant positive effect.
