Abstract
The invention relates to a preparation method of acrylic resin. The preparation method comprises the specific steps of: firstly putting 10-30 parts by weight of styrene into a reaction vessel, and heating to a backflow state; then uniformly mixing 60-70 parts by weight of methyl methylacrylate, 2-5 parts by weight of methyl acrylate, 5-15 parts by weight of butyl acrylate, 1-3 parts by weight of acrylic acid ethyl ester and 0.5-1 parts by weight of 2,2'-Azobis(2-methylpropionitrile), then dropwise adding a mixture to the reaction vessel within 1-3 hours while stirring, and simultaneously controlling the inner temperature of the reaction vessel to the backflow temperature of styrene; and after finishing dropwise addition, maintaining the temperature and stirring, reacting for 3-5 hours, and then reducing temperature and filtering. The acrylic resin prepared by the method has good impact resistance, heat resistance and liquidity.
Description
Technical field
The present invention relates to the thermoplastic resin technical field, especially relate to a kind of thermoplastic acrylic resin.
Background technology
Acrylic resin is the better thermoplastics of a kind of performance, is widely used in the fields such as decoration, decoration, polyblend, packing, especially gains great popularity with its high transparency.But it is relatively poor aspect toughness, and thermotolerance is not high, thereby has limited its application.
Summary of the invention
For the problems referred to above that prior art exists, the applicant provides a kind of preparation method of acrylic resin.The acrylic resin that present method prepares has good shock resistance, thermotolerance and flowability.
Technical scheme of the present invention is as follows:
A kind of preparation method of acrylic resin, concrete steps are as follows:
At first 10 ~ 30 parts of vinylbenzene are dropped into reaction vessel, be heated to reflux state; Then after 60 ~ 70 parts of methyl methacrylates, 2 ~ 5 parts of methyl acrylates, 5 ~ 15 parts of butyl acrylates, 1 ~ 3 part of ethyl propenoate, 0.5 ~ 1 part of azo-bis-isobutyl cyanide being mixed, in 1 ~ 3 hour, be added dropwise to reaction vessel, keep during dropping stirring, controlling simultaneously the interior temperature of reaction vessel is cinnamic reflux temperature; After dropwising, keep temperature and stirring, reacted 3 ~ 5 hours, then cooling is filtered and is got final product; Above-mentioned part refers to mass fraction.
The technique effect that the present invention is useful is:
The onepot coating that the prepared acrylic resin of the present invention and aluminium powder, pigment, auxiliary agent etc. are made has quick-drying under the normal temperature, and hardness is high, good impact resistance, and sticking power is good, and the characteristics such as aluminium powder good attachment can be widely used in ground and be the plastic paint field of ABS etc.
