Abstract
The invention discloses a polyester polyol epoxy resin flexibilizer. The polyester polyol epoxy resin flexibilizer comprises following raw materials, 1.0 carboxyl equivalent weight of an aromatic polybasic carboxylic acid or/ and an acid anhydride, and 1.2 to 2.0 hydroxy equivalent weight of a dihydric alcohol. Comparing with existing technologies, the molecular chains of the polyester polyol epoxy resin flexibilizer have flexible chain structures, and aromatic rings which have rigid structures, so that toughening performance of the polyester polyol epoxy resin flexibilizer is excellent, and a problem of existing technologies is solved. Wherein the problem is that, it is impossible to take flexibility, thermal deformation temperature, and high temperature performances of cured materials into account at the same time.
Description
Technical field
The present invention relates to a kind of epoxy resin toughener, be specifically related to a kind ofly adopt aromatic polycarboxylic acid or/and the polyester polyol toughner that acid anhydrides and dibasic alcohol condensation are made.
Background technology
Epoxy resin is owing to having moderate cost, the characteristics such as widely applicable, thereby is widely used in the every field such as electron and electrician, building materials, machinofacture, military project.But the fragility of curable epoxide thing is bigger than normal, therefore while applying, generally all need to process through the toughening modifying of necessity the effect that can obtain comparatively to be satisfied with.The more epoxy resin toughener of industrial application mainly contains at present: the main chains such as polyether glycol, end carboxylic rubber, long-chain fat amine are the compound of flexible chain, the toughening effect of these toughner is all right, but during ubiquity toughner large usage quantity, the heat-drawn wire of cured article and the more shortcoming of high-temperature behavior decline.
Summary of the invention
The polyester polyol epoxy resin toughener that provides a kind of main chain to contain aromatic ring is provided for above-mentioned the deficiencies in the prior art.
Technical scheme of the present invention:
A kind of polyester polyol epoxy resin toughener, its raw materials comprises the composition of following equivalence ratio:
Aromatic polycarboxylic acid is or/and acid anhydrides is 1 carboxyl equivalent; Dibasic alcohol is 1.2 ~ 2.0 hydroxyl equivalents.
Described aromatic polycarboxylic acid is or/and acid anhydrides is one or more in Pyromellitic Acid, trimellitic acid, bibenzene tetracarboxylic, pyromellitic acid anhydride, trimellitic anhydride and bibenzene tetracarboxylic dianhydride.
Described dibasic alcohol is one or more in 1,3-PD, BDO, 1,5-PD, ethylene glycol, glycol ether, triglycol and Tetraglycol 99.
The production technique of polyester polyol epoxy resin toughener of the present invention does not have essential distinction with the production technique of general vibrin.
Compared with prior art, advantage of the present invention is: polyester polyol toughner of the present invention, owing in molecular chain, not only containing the flexible chain structure, also contain the aromatic ring with rigid structure, therefore while being applied to epoxy resin roughening, not only toughening effect is good, has also overcome simultaneously the snappiness of cured article and the shortcoming that heat-drawn wire, high-temperature behavior can not be taken into account simultaneously in the prior art, can not cause because of the introducing of toughner the phenomenon of cured article heat-drawn wire and high-temperature behavior excessive descent.
