Description
Technical field
The present invention relates to a kind of preparation methods of acrylic resin, especially a kind of organic molten without using toxic volatile
The preparation method of the environment-friendlyacrylic acrylic acid resin of agent, surfactant and water, and by the method preparation acrylic resin and
Its purposes.
Background technique
The method for preparing acrylic resin is currently known technology, mainly uses three kinds of polymerization methods, is solution respectively
Polymerization, emulsion polymerization, bulk polymerization.
Polymerisation in solution refers to monomer and initiator being dissolved in the polymerization reaction carried out under solution state in appropriate solvent,
Such as the technical solution of the patent disclosures such as CN201510221322.3, CN201510137539.6.However, in a manner of polymerisation in solution
The acrylic resin of preparation generallys use the poisonous and hazardous volatile organic solvent such as toluene, dimethylbenzene, ethyl acetate, and easy pair
Human body damages, and pollutes environment.
Emulsion polymerization refers to that polymerized monomer by emulsifier and mechanical stirring, makes monomer be dispersed in water to form lotion,
Add the skill that initiator causes the patent disclosures such as monomer polymerization, such as CN201410281051.6, CN201610312484.2
Art scheme.Water is used in emulsion polymerization as reaction medium, although not using toxic organic solvents, and using organic
Solvent is compared as reaction medium, and the energy consumption of emulsion polymerization is larger, and the use of surfactant will affect in polymerization process
Final products performance can generate a large amount of waste water in product surface activating agent subtractive process, and this preparation method cannot still expire
Sufficient current demand.
Bulk polymerization refers to monomer under conditions of not solubilizer and other dispersing agents, by initiator or light, heat, spoke
The polymerization reaction that its own carries out polymerization initiation under the effect of penetrating, such as CN201510034454.5, CN201210312635.6 etc.
The technical solution of patent disclosure.For the polyacrylate of bulk polymerization preparation without dispersing agent, product is pure, does not need complicated point
From, purification operations, but in polymerization process, fuel factor is relatively large, and auto-acceleration effect causes product to have bubble, discoloration；This
Outside, it is continuously increased due to system viscosity with polymerization, mixing and heat transfer difficult, it may appear that polymerization automatically speeds up phenomenon, causes implode.
Bulk polymerization is not easily controlled the molecular weight distribution of product, and residual monomer is difficult to eliminate, the enforcement difficulty in terms of industrial production
It is larger.
Therefore, in order to solve the problems, such as current acrylic resin preparation method, it is desirable to provide a kind of environmental protection propylene
The preparation method of acid resin does not use toxic volatile organic solvent and surfactant, the environmental protection for not generating waste water especially
The preparation method of acrylic resin, while being able to solve that do not add can not heat dissipation problem caused by dispersing agent.
