Description
Technical field
The present invention relates to a kind of coating, and in particular to a kind of impact-resistant acrylic resin of environmentally friendly high rigidity and its preparation
Method, belongs to technical field of polymer materials.
Background technology
Impact property is a kind of traditional performance of coating, mainly in car paint, and ratio is required in terms of engineering machinery coating
It is higher, it will necessarily reduce the hardness of coating while conventional thermosetting acrylic resin improves impact property at present.From structure
From the point of view of coating impact property with resins synthesis when the long Isooctyl acrylate monomer of the ester chain that uses it is relevant, the present invention is adopted
With hy-droxybutyl so that the impact property that resin can still have under higher hardness.
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 high rigidity
Excellent acrylic resin of impact property and preparation method thereof.
Technical scheme, to realize object above, the technical solution adopted by the present invention is：
A kind of impact-resistant acrylic resin of high rigidity, it is made up of the raw material of following weight percents：
Methyl methacrylate 30%-35%, hy-droxybutyl 7.4%-10%, butyl acrylate 2.5%-5%, third
Olefin(e) acid 1-2%, initiator 2%-3%, organic solvent 30%-50%.
A kind of preparation method of the impact-resistant acrylic resin of high rigidity, it comprises the following steps：
(1) initiator of methyl methacrylate, butyl acrylate, hy-droxybutyl, acrylic acid, 90% deal is mixed
Close uniform, 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, and mix monomer is added dropwise, and time for adding is that 2.5-3 is small
When；2 hours are kept at reflux；Insulation finishes the initiator for adding remaining 10% deal；It is incubated 2 two hours；
(4) reaction is cooled to 100 DEG C after terminating, and filtering obtains acrylic resin.
Preferably, the preparation method of the impact-resistant acrylic resin of above-described high rigidity, methacrylic acid
The percentage by weight of methyl esters is that 30%-35%, the percentage by weight of hy-droxybutyl are 7.4%-10%, butyl acrylate
Percentage by weight be 2.5%-5%, the percentage by weight of acrylic acid be 1-2%, the percentage by weight of initiator be 2%-3%,
The percentage by weight of organic solvent is 30%-50%.
Preferably, the preparation method of the impact-resistant acrylic resin of above-described high rigidity, organic solvent is
Dimethylbenzene；Initiator is TBPB (peroxidized t-butyl perbenzoate).
The present invention is screened by many experiments, and the cross-linking monomer commonly used in acrylic resin is hydroxy-ethyl acrylate and propylene
Sour hydroxypropyl acrylate, the acrylic resin impact synthesized using these carboxylic monomers will reach that 50Kg.cm hardness of paint films need to be reduced to
Once, the present invention passes through the resin of Select to use hy-droxybutyl synthesis to 1H, and in the case where hardness reaches 2H, impact is appointed
50Kg.cm can so be reached.
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 impact resistance
Energy.
