Description
Technical field
The invention mainly relates to new material technology field, specifically a kind of novel environment-friendly water-based resin phase transformation hydrated agent and its
Manufacturing process.
Background technique
Thermosetting resin (refers mainly to phenolic resin, epoxy resin, furane resins, organic siliconresin, polyurethane resin, second
Alkenyl esters resin and unsaturated polyester resin) as the nonmetallic anti-corrosion material of production thermosetting property and structural material, it is excellent with its
Physical and mechanical property and corrosion resistance, good weatherability, long-life and convenient processing performance, are widely used in anticorrosion, stone
Oil, metallurgy, electric power, space flight, aviation, national defence, heat exchange, dirt-proof, ship, ocean engineering protection, pharmacy, building materials, is given chemical industry
The industries such as draining, engineering machinery, environmental protection.But these thermosetting resins produced and used extensively both at home and abroad at present all exist in life
Smell is big, cross-linking monomer and organic solvent are volatile, long-term use temperature is low, operation before production, use process neutralization are fully cured
The disadvantage of bad environments.
Thermosetting resin is not soluble in water, is dissolved only in the organic solvents such as aromatic hydrocarbon, alcohol, ketone and esters.Organic solvent is inflammable, easy
The disadvantages of quick-fried, toxic, pollution environment, damage operator's health, knot production, storage and transportation and construction bring inconvenience.With ring
The enhancing for protecting consciousness, takes water as a solvent or the water-base resin of decentralized medium is more and more taken seriously.Using water as decentralized medium or molten
The water-base resin of agent is not only environmentally friendly material, and application property is good that (low viscosity, impregnability be good, room temperature curing, nontoxic
Property, volatility be small, environmental-friendly etc.), it can construct on wet surface, it is of less demanding to construction environment, it is easy to clean, storage and transportation and make
With safety, price is also cheap, thus becomes the developing direction of domestic and international production of resins application.
The distinguishing feature of water-base resin is: to inorganic face, filler and glass fibre wellability are good, have good mechanicalness
Energy, processing performance are good and have the characteristics that anti-flammability, low-shrinkage.
As countries in the world are to the pay attention to day by day of environmental protection, exploitation does not contain volatile organic compounds, prepares ring
Water-base resin, coating and the product of guarantor's type have become the new development trend of Resin Industry.
The main preparation methods of water-base resin:
1. direct emulsion process
Direct emulsion process is also known as Mechanical Method.Refer to after resin is added in blender, the aqueous solution of emulsifier is added, passes through
Uniform particle is dispersed in water by mechanical stirring;Resin and emulsifier can also directly be mixed, after being heated to temperature appropriate
Mechanical stirring is carried out, gradually adds water in whipping process, forms lotion.The characteristics of direct emulsion process is low in cost, preparation process
Simply.Shortcoming is that the aqueous resin dispersion system stability for preparing is poor, and the size of dispersion particle it is larger > 10 μm.
Phase transformation 2. (phase reversal) method
Phase inversion is the volume by changing water phase, and polymer is transformed into oil-in-water state from Water-In-Oil state, is
A method of effectively preparing macromolecule water baseization system.The advantages of phase inversion is, can by most macromolecule resin,
Corresponding water baseization system is made in the method for crossing physics emulsification, has greatly widened it and has prepared range.
3. chemic modified method
Chemic modified method is also known as self-emulsification.It is to be introduced polar group on molecular resin skeleton by chemical reaction,
Hydrophilic and oleophilic amphipathic characteristic is made it have, to have the function of being similar to surfactant.The characteristics of chemic modified method is system
The emulsion-stabilizing obtained, particle size is small, mostly nanoscale, but its preparation process is complicated, it is difficult to control, and higher cost.
4. curing agent emulsion process
Curing agent emulsion process be by polyamine curing agent chain extension, grafting, at salt, become aqueous dispersible curing agent.This
Kind curing agent has the molecular structure of resin, can be used as cationic emulsifier and emulsifies to resin, obtains stable cream
Liquid.
Thermosetting resin mutually becomes aqueous thermosetting resin, and key is that organic solvent resin is dissolved in water or is scattered in water,
Form the phase transformation hydrated agent of uniform and stable liquid.Phase transformation hydrated agent not only plays chemistry to resin and changes in resin hydration process
The effect of property, and play phase reversal to resin.
Therefore, a kind of novel aqueous resin phase transformation hydrated agent new and effective, adaptable to resin is developed, in thermosetting property
Production of resins and its composite material manufacture view have vast market prospect, for reducing environmental pollution, sustainable development war
Slightly it is of great significance to.
