Description
Technical field
The present invention relates to a kind of air neutralization under water all can photo-thermal repair thermoplastic material.
Background technology
The world today, polymer materials especially thermoplastic, polymeric materials is widely used in the high-technology fields such as Aeronautics and Astronautics, electronics, machinery because of the performance of its excellence.But thermoplastic, polymeric materials in use, due to the impact by machinery or the factor such as chemical, inevitably produce damage, even slight scraping also can form tiny crack in the material, even and this tiny crack also generation can expand the damage that become macroscopic view gradually, thus cause material mechanical performance to decline to such an extent as to reduce work-ing life of thermoplastic, polymeric materials.In order to solve thermoplastic, polymeric materials damage, a large amount of researchists repairs the principle of damage by mimic biology body self, invents the thermoplastic, polymeric materials with certain repair ability.Wherein the U.S. in the starting of this field comparatively early, in late 1980s, along with the development and progression of material technology and large-scale integrated circuit technology, US military first proposed this imagination of material and concept with repairing effect, just expands large-scale investigation and application afterwards.This field is nowadays developed very fast, and the application of thermoplastic, polymeric materials has very extensive, and receives more and more higher attention.Therefore, there is thermoplastic, polymeric materials one of research emphasis becoming this field of certain repairing effect.
Similar organism, has the thermoplastic, polymeric materials of certain repairing effect, under certain external stimulus, can make suitable reparation reaction, thus recover himself performance to damage position.Whether at present, the sorting technique of self-repair material is a lot, according to using renovation agent can be divided into foreign aid's type and the large class of eigenmode two.Typical foreign aid's type restorative procedure is adulterate in thermoplastic, polymeric materials a certain amount of microcapsule or tubular fibre, renovation agent is carried with bag, after material receives damage, the microcapsule wherein adulterated or tubular fibre can discharge renovation agent auto-mending damaged part.Typical eigenmode restorative procedure is then utilize the reversible chemical reaction that exists in system and carry out selfreparing, and these chemical reactions comprise Diels-Alder reaction, dynamically covalent chemical, cystine linkage reaction, the supramolecular structure containing hydrogen bond, p-p pile superimposition ionic polymer etc.After the thermoplastic, polymeric materials of the type receives damage, simple external stimulus (as heating, microwave etc.) can be passed through and impel this material generation reversible chemical reaction, thus repair damaged part.In general, the thermoplastic, polymeric materials the repaired manufacturing cost of foreign aid's type is higher, and preparation process is comparatively complicated and reparation number of times is limited.And intrinsic selfreparing to there is remediation efficiency not high yet, repair time is longer, the challenge improving controlling and reduce costs.
Except being processed into except the workpiece of needs as block materials, thermoplastic, polymeric materials uses as protective coating also wide market, and it can not be swiped by maximized protecting group bottom materials, the harm of corrosion etc.But it is faced with equally once damage the problem sharply failed being difficult to cause protection function as coating.And in the use procedure of coating, especially the protective coating on underwater pipeline or equipment, even once there is the very damage such as the crackle of small area or broken hole, all can be serious affect its protection function, and after generally all needing dismounting, the complicated operation such as recoat just can be reused.This not only substantially increases cost, also certainly will on productive life cause serious impact even serious time can produce safety problem.
Summary of the invention
Technical problem to be solved by this invention is to provide the neutralization of a kind of air under water all can the thermoplastic material repaired of photo-thermal, and being irradiated by infrared lamp, near-infrared laser lamp or infra-red roast light after this thermoplastic material is impaired can in atmosphere or reparation quick and easy under water.Photothermal technique is imparted in polymer materials by the present invention, and general thermoplastic, polymeric materials all can use, and its preparation process also meets green continuable basic demand.Dependence test proves: material of the present invention can realize being rapidly heated at short notice, and temperature can higher than the glassy phase invert point of thermoplastic polymer, thus certain reparation is realized at short notice to the thermoplastic material after impaired, especially for the coating used under water, can original position repair, and with low cost, practicality is higher.
Air neutralization under water all can photo-thermal repair a thermoplastic material, it is characterized in that this material prepares by the following method:
