Description
Technical field
The invention belongs to technical field of aqueous paint, and in particular to a kind of non-ion aqueous polyamide curing agent and its system
Preparation Method.
Background technique
Traditional solvent epoxy varnish coating is because having good adhesive force height, wearability, chemical-resistant and solvent resistance
It excellent, the features such as hardness is high, industrially has been obtained and is widely applied.However as domestic and international related environmentally friendly standard requirements
It is increasingly strict, develop low VOC (volatile organic compounds) aqueous epoxy resin systems and related coating products, increasingly by
To the concern and research of domestic and international scientific research technical staff.Aqueous epoxide resin paint physical and chemical properties are excellent, be readily produced,
Storage, construction, smell is smaller, safety and environmental protection is nontoxic, therefore becomes the kind of water paint focus development.And in water-base epoxy tree
In the exploitation of grease coating material, the Water-borne modification of curing agent and modification occupy very big specific gravity.
Currently used aqueous epoxy resin curing agent method of modifying can substantially be divided into three kinds: (1) by polyamine and monoester
Amidated polyamines is made in the reaction of fat acid；(2) polyamide is formed by polyamine and dimeric dibasic acid condensation；(3) by polyamine and epoxy
Resin addition obtains polyamine-epoxy addition product.And common method of modifying (3) can be broadly divided into following two categories:
Typical one kind method of modifying is to introduce to have preferable hydrophily, the longer polyethers knot of segment in curing agent structure
Structure.If Chinese invention patent CN101007863A discloses a kind of preparation method of nonionic aqueous epoxy resin curing agent,
This method is by the mixture of polyether polyol diglycidyl ether or polyether epoxy or both and aromatic polyamine or rouge
Fat race polyamines carries out chain extending reaction, the further chain extending reaction of epoxy resin progress is then added, non-ion aqueous asphalt mixtures modified by epoxy resin is made
Rouge curing agent.However the biggish polyether segment of molecular weight is introduced in this method, during film-forming not with epoxy resin
Cross-linking reaction, so that film forming matter mechanical property is not high, hardness is lower, simultaneously as the presence of the preferable polyether segment of hydrophily is dropped
The low water resistance of paint film.
Another kind of method of modifying be by be added organic acid be neutralized into salt adjust hydrophilic lipophilic balance it is relatively good to obtain
Emulsifiability and curing performance.As to disclose a kind of ionic aqueous epoxy resins solid by Chinese invention patent CN101402720A
The preparation method of agent, this method first block polyethylene polyamine with mono-epoxy compounds, and liquid asphalt mixtures modified by epoxy resin is then added dropwise
Rouge carries out chain extension, adds organic acid and is neutralized into salt, is finally diluted with water to obtain a kind of ionic aqueous epoxy resin curing agent.
But this method, which is neutralized into salt by organic acid, improves its hydrophily, the presence of organic acid can make metal body be easy to occur
Flash rusting phenomenon；In addition, due to the addition of organic acid, so that the ionic waterborne curing agent has one to the selection of pigments and fillers and auxiliary agent
Fixed limitation.
