Description
Technical field
The present invention relates to a kind of coating, and in particular to a kind of environmentally friendly high rigidity acrylic resin of resistance to gasoline and its preparation side
Method, belongs to technical field of polymer materials.
Background technology
The resin of resistance to gasoline is mainly used in fuel tank, and lathe etc. needs the industrial part that oil resistant corrodes, and conventional acrylic resin exists
There is paint film softening after film forming fast, gloss reduction is rapid, paint film such as can not recover at the disadvantage after oil plant volatilization
The content of the invention
Goal of the invention：The purpose of the present invention is that in view of the shortcomings of the prior art, by many experiments, there is provided a kind of environmentally friendly
High rigidity, the acrylic resin of resistance to gasoline and preparation method thereof.
Technical scheme, to realize object above, the technical solution adopted by the present invention is：
A kind of high rigidity acrylic resin of resistance to gasoline, it is made up of the raw material of following weight percents：
15%-25% styrene, 2.5%-25% methyl acrylates, 5%-10% hydroxy-ethyl acrylates, acrylic acid
0.25%-1.5%, initiator 0.5%-2.5%, organic solvent 50%.
A kind of preparation method of the high rigidity acrylic resin of resistance to gasoline, it comprises the following steps：
(1) initiator of styrene, methyl acrylate, hydroxy-ethyl acrylate, acrylic acid, total amount 90% is well mixed,
Obtain mix monomer；
(2) organic solvent is put into reactor, is heated to reflux state；
(3) monomer that step (1) is well mixed is put into dropping tank, then toward mix monomer is added dropwise in reactor, is added dropwise
Time is 2.5-3 hours；Then keep at reflux 2 hours of reaction, insulation reaction adds residue 10% after finishing
Initiator, thermal reacting for two hours；
(4) 100 DEG C are cooled to, filtering obtains acrylic resin.
Preferably, the preparation method of the above-described high rigidity acrylic resin of resistance to gasoline, it is characterised in that each
The percentage by weight of raw material is as follows：
15%-25% styrene, 2.5%-25% methyl acrylates, 5%-10% hydroxy-ethyl acrylates, acrylic acid
0.25%-1.5%, initiator 0.5%-2.5%, organic solvent 50%.
Preferably, the preparation method of the above-described high rigidity acrylic resin of resistance to gasoline, organic solvent is two
Toluene；Initiator is BPO (perbenzoic acid).
The present invention is screened by many experiments, and the monomers such as butyl acrylate and Isooctyl acrylate monomer are used in conventional formulation
When, oil resistivity is less than 12 hours.The present invention uses the shorter raw material of carbochain instead by experiment screening in material component, synthesizes
Obtained resin gasoline-resistant performance is brought up to 48 hours, achieves extraordinary technique effect.
Beneficial effect：Compared to the prior art, the present invention has the following advantages：
The present invention obtains optimal raw material by many experiments screening and constitutes and match, and is preferably gone out by many experiments optimal
Synthesis technique.Whole preparation technology is reasonable in design, and the acrylic resin prepared has excellent hardness, and with very
Good gasoline-resistant performance.
