Description
Technical field
The present invention is to be related to a kind of acrylic resin, specifically, is to be related to one kind to have good phase with environment-friendlyplasticizer plasticizer
The acrylic resin of capacitive, belongs to acrylic materials technical field.
Background technology
PVC (polrvinyl chloride) is a kind of application general-purpose plastics widely, is mainly used in tubing, sheet material, undulation degree
The fields such as material, membrane material, plastisol.Wherein, pvc plastisol is the main seal glue of automobile, about China's automobile adhesive
1/3.In recent years, the pay attention to day by day with people to Environmental Health, some problems that PVC brings also increasingly are closed by people
Note, for example：Residual monomer vinyl chloride in PVC, migrates out product surface with the time, and larger shadow can be caused to health
Ring；The combustion product bioxin meeting serious environment pollution of PVC, has strong carcinogenecity, and can cause deformity, can be to human body
Immunologic function and reproductive function cause to damage.In addition, the heat stability of PVC product, weatherability are poor, in heat, oxygen, light
Under effect, PVC can remove HCl formed conjugated bonds and make resin discoloration, product become fragile, degradation.
Acrylic resin be by esters of acrylic acid and methyl acrylic ester and other resins made by olefinic type monomers copolymerization,
With excellent light resistance and anti-outdoor aging performance, and biodegradable in the environment and chemical degradation, combustion product
Predominantly carbohydrate, environmental sound.Therefore, gradually adopt acrylic resin to substitute PVC at present to use.
In order that plastics have good toughness, film property, it will usually the plasticizer for adding property compatible good wherein,
Domestic main plasticizer is phthalate material at present, such as：DOP (dinoctyl phthalate), DEHP neighbour's benzene
Dioctyl phthalate two (2- Octyl Nitrites).But, this kind of plasticizer has heavy damage to the healthy reproduction of the mankind, especially child, together
When also can to environment, therefore, many countries have begun to disable phthalate material, the substitute is
Novel environment-friendlyplasticizer plasticizer, such as Yi Siman TXIB, DOTP of successful commercialization etc..The environment-friendly type plasticising such as TXIB, DOTP at present
Agent is primarily adapted for use in PVC plastic, for example：A kind of Chinese patent " the disposable handss of environmental protection polyvinyl chlorides of CN201110318486.X-
In the preparation method of set " using DOTP as PVC plastic product plasticizer, product is nontoxic, excellent performance；Chinese patent
With DOTP as plasticizer system in " a kind of preparation methoies of environmental protection polyvinyl chloride aqueouss artificial leather of CN201510146563.6- "
Standby dermatine, meets the environmentally friendly high request both at home and abroad to synthetic leather；A kind of Chinese patent " systems of CN201110428652.1-
The method of the standby pvc plastisol for including NBR " is using TXIB as plastisol plasticizer.
Acrylic resin will replace PVC, it is also desirable to possess and PVC identicals film property and toughness, therefore, it is also desirable to add
The good plasticizer of property compatible, but, the environment-friendlyplasticizer plasticizer compatibility such as current acrylic resin and TXIB, DOTP is not
It is good, there is presently no with regard to the environment-friendlyplasticizer plasticizers such as TXIB, DOTP are added in acrylic resins with improve its toughness,
The relevant report of film property.
