Description
Technical field
The invention belongs to epoxypaint field, particularly a kind of epoxy alkyd resin and high rigidity quick-reaction type coating thereof.
Background technology
Wood furniture is by the external coating of different process, can play the effect of protection furniture, makes loose ground more solid, allows furniture have the good performance such as water-fast, wear-resisting, corrosion-resistant.Timber is carried out to application, and reaching desirable application object is not to be easy to thing, mainly contains several important reasons: the Density inhomogeneity that (1) is wooden and porousness, require coating to have good sticking power.(2) property complicated and changeable of processing environment and environment for use, requires coating to have hardness high, and wear resistance is good, guarantees the persistence of paint film.(3) for speciality coating, because needs are under extreme conditions used, so it is high temperature resistant to require coating to have, chemical resistance, hardness high.Coating in use often can run into, and causes not wear-resisting, the problem of scratch resistant not because coating hardness is not high, and for this problem, the way conventionally adopting is carry out resin modified or add hard filler.But it is far from being enough only depending on wear resistance and the hardness of using hard powders to increase coating, and use hard powders when improving hardness, the snappiness of coating can significantly decline, and the fragility of coating increases, and when being subject to External Force Acting, is very easy to destroyed.So improving hardness by resin modified becomes inevitable.
On epoxy resin molecular chain, contain the groups such as carboxyl, hydroxyl, epoxy group(ing), therefore there is good mechanical property and physicochemical property.Epoxypaint becomes cancellated macromole by crosslinked in drying process, and the paint film after solidifying has that good erosion resistance, hardness are high, wear resistance and the good feature of sticking power.Shortcoming is only to pass through simple epoxy resin cure, poor, the easy efflorescence of paint film fullness ratio.Synolac over-all properties is moderate, and the coating of preparation has good snappiness and from dryness.By epoxide modified from dry alkyd resin, both kept Synolac from dryness and snappiness, there is again good erosion resistance and the high rigidity of epoxy resin.In prior art, for epoxy resin and Synolac modified paint, carried out more research; conventionally epoxy alkyd resin is all to utilize epoxy resin to replace part polyvalent alcohol; in polyreaction, directly epoxy resin is introduced in alkyd polymer, then in the polymerization later stage, added gradually polyprotonic acid to prevent reaction gel.During with this method synthesizing epoxy modified alkyd resin, owing to being single step reaction, the shared ratio of epoxy is conventionally less, because if the shared ratio height of epoxy words can be easy in reaction process, occur gel, so low epoxy content often causes soft.Having in addition research to claim can be first by epoxy resin and fatty acid response synthesizing epoxy ester, and then epoxy ester carries out transesterify with Synolac again.During with this method synthesis modification resin, transesterify extremely difficulty reacts completely, and the by product that produces of transesterify can cause waste to the environment ，Dui manufacturer that works the mischief, and has the slow and not wear-resisting problem of dry speed.
Therefore, seek a kind of technique simple, product possesses again that hardness is high, wear resistance good, the production method of the modified alkyd resin of fast drying simultaneously, and tool is of great significance.
