Description
Technical field
The present invention relates to high resistance to compression type unsaturated polyester resin, particularly strengthen the shock-proof pressure-tight resin of toughened unsaturated polyester resin with polyurethane.
Background technology
One, unsaturated polyester (UPR) resin
Vorlander just synthesized unsaturated polyester with toxilic acid and ethylene glycol as far back as 1894, and that the preparation method of definite polyester and structure thereof is Carothers.Flory etc. have carried out detailed research to the reaction kinetics of polyester, the copolymerization speed of finding unsaturated polyester and unsaturated thinner afterwards is than fast 30 times of the autohemagglutination speed of unsaturated polyester own, the thinner that adopts is a vinyl acetate between to for plastic, and this great discovery makes unsaturated polyester obtain large-scale the application.Typical unsaturated polyester is synthetic by following material: 1, and 2-propylene glycol, Tetra hydro Phthalic anhydride and maleic anhydride.Monounsaturated dicarboxylic acid can change the performance of resin, and Tetra hydro Phthalic anhydride can be given polyester with intensity, reduces the crystallization tendency of polyester, and is good with the vinylbenzene compatibility.With m-phthalic acid synthetic unsaturated polyester with compare with Tetra hydro Phthalic anhydride synthetic unsaturated polyester, its physical strength, heat-resisting and chemical resistance all obtain to improve.But because its reaction difficulty, so normal employing two step method reaction.
Unsaturated polyester need come crosslinked with it with cross-linking monomer (or claiming thinner), and in addition, cross-linking monomer can be diluted unsaturated polyester, can and increase rate of drying thereby obtain excellent application performance.The selection of reactive diluent is extremely important, because the reactive height of vinylbenzene and maleic acid ester, thereby be widely used as thinner most.
Unsaturated polyester resin is a kind of of thermosetting resin, its characteristics be easy to operate and solidify after superior performance is arranged, for example viscosity is low, can freely adjust solidified nature.Solidify the back resin and the favorable mechanical performance is generally arranged, electric property, water tolerance, acid resistance and oil-proofness.It is more cheap than other resin material that these performances are added price, make it except can be applicable to coating, style strip, tackiness agent, electrical appliance, button, ornament etc., also can be used for resin concrete, putty (putty) etc., also be applied to fields such as motor, machinery, aviation, automobile, chemical industry, electronics in addition.
