Description
Technical field
The present invention relates to chemical technology field, particularly a kind of synthesis technique of short oil aqueous alkide resin.
Background technology
Phthalic resin coating has that paint film combination property is preferable, raw material is cheap and easy to get, technical maturity is stable and independent of stone
The advantages that oily resource, but traditional solvent-borne alkyd resins contain a large amount of organic solvents in the production and use process, these
Organic solvent can be discharged into air in construction stage and drying process, cause high risks, and caused volatile organic matter is
The main reason for indoor pollution.With the limitation of environmental regulation and the increasingly enhancing of people's environmental consciousness, environmentally friendly water
The developmental research of property alkyd resin receives the attention of people.
Therefore water paint, introduces the water into coating because water is nontoxic, tasteless, non-ignitable and cheap, can both reduce production
Cost, VOC content is substantially reduced again, so water paint is just able to fast development.But exactly because the introducing of water is brought again
A series of new problem, such as the evaporation latent heat of water are very big, and accelerating to dry needs to improve temperature, and the evaporation rate of water is by phase
Influence to humidity is very big, and the surface tension of water is very big, and scattered and coating the coating to pigment all adversely affects, and works as water
When property coating is applied to metallic matrix, because the high conductivity of water may cause matrix corrosion etc..It is past in order to solve the above problems
Toward the method using the auxiliary agent such as addition cosolvent, surfactant and reducing agent in coating, and the addition of these auxiliary agents is not
Bring certain negative effect with can avoiding.In a word, the preparation of water paint is complicated far beyond solvent based coating, there is also some not
Foot part, but because it can greatly reduce VOC content, environmentally friendly trend is complied with, and disclosure satisfy that the performance under many occasions
It is required that still there are very big market prospects.
