Abstract
The invention discloses a method for coating shells by adopting a parylene vacuum coating technology and relates to a shell coating method. The method comprises the following steps: classifying the shells, removing impurities, polishing the shells into shell base materials of a certain size, performing surface modification, putting the shell base materials subjected to modification treatment into special vacuum vapor deposition equipment, evaporating and sublimating solid-state raw materials of a certain mass under the condition of 120 DEG C/1.3mPa, gasifying under the condition of 650 DEG C/1.3mPa, performing carbon-carbon chain splitting on two side chains to generate stable activated monomers, and finally, introducing the two activated monomers into a deposition chamber in the state of room temperature 25 DEG C/1.3mPa for performing polymerization and deposition, and performing flash polymerization on the shell base materials subjected to surface modification treatment to prepare a parylene film. According to the method, the problem that the shell decorative sheet is easy to oxidize and discolor and low in acid-base resistance and corrosion resistance is solved, and the method has good market prospects and application values.
Description
Technical field:
The present invention relates to a kind of coating method of shell, be specifically related to a kind of parylene of employing vacuum evaporation technology shell is carried out the method for film.
Background technology:
Water pearl culture and deep processing are that some lean on lake mainstay industry in the neighbourhood, are developed rapidly in recent years, and along with the continuous expansion of water pearl culture and process scale, the problem of environmental pollution that the shell waste of generation brings seems day by day serious.Therefore, the shell of how processing in generation and the course of processing becomes an important problem gradually, along with advancing by leaps and bounds of science and technology, people gradually pay attention to the comprehensive development and utilization of this recyclability resource of shell, economic benefits, exploitation main path to shell has: utilize shell pearl core processed, for artificial marine cultured pearl provides pearl core, make the additive of various uses, as the various gas of absorption and liquid impurity, the novel absorption material of various bacteriums, as food preservative etc., can also utilize the native texture of shell and unique performance to be processed into consumption large, good in economic efficiency pearl shell decorative sheet, at present, adopt shell to be processed into the patent of artwork and building materials, document is also of common occurrence, patent 200710027598.3 is that shell seccotine is bonded at and on marble, pieces out layout together, although the product utmost point of making is composed aesthetic feeling and artistic appeal, but after destroying, the stratum corneum that shortcoming is shell can not be effectively protected, therefore its oxidation resistance is poor, weathering resistance is poor, easily variable color, therefore how to adopt the method for science to carry out effectively protecting and seeming particularly important to shell base material.
Summary of the invention:
The object of this invention is to provide a kind of parylene of employing vacuum evaporation technology and shell is carried out to the method for film, it has prevented that shell from losing stratum corneum protection because processing polishing effectively, by acid, water, oxygen, the corrosion phenomenon from inside to outside that is harmful to chemistry etc. and cause, simultaneously, Parylene does vapour deposition under vacuum environment, no matter thereby shell is steep edge, crack, or trickle pin hole inwall can effectively permeate, and uniformity everywhere, and the shell after film has very strong acid and alkali-resistance, humidity, resistance to going mouldy, anticorrosive, high insulation high-low temperature resistant and good biocompatibility, thoroughly solve common pearl shell decorative sheet oxidizable, variable color, acid and alkali-resistance, the difficult problem that resistance to corrosion is poor, there is good market outlook and using value.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: its method is: 1, surface modification: simply classify according to the quality color and luster of fresh water shell, carry out impurity elimination processing, then be polished into the shell base material of a certain size specification, in the ethanol solution of the silane coupling agent that is 0.05～0.5% in mass concentration, under 25～35 DEG C of conditions, flood 30～90S, then be placed under 25～35 DEG C of conditions fully dryly, just obtained the shell base material after surface modification treatment; 2, vacuum moulding machine and film: in special vacuum phase deposition equipment, under 120 DEG C/1.3mPa condition, the solid feed of certain mass is evaporated, distilled, under 650 DEG C/1.3mPa condition, gasify again, two side chain carbon demolases are generated to stable reactive monomer, latter two reactive monomer enters simultaneously and in the sediment chamber under 25 DEG C/1.3mPa of room temperature state, carries out aggregation deposition, carried out instaneous polymerization on the shell base material after surface modification treatment and become parylene film, parylene film gauge control is at 25～30um.
Described solid feed is to be formed according to the mixed in molar ratio of 1:0.1～2.0 by a chloro p-Xylol ring disome and p-Xylol ring disome.
Described silane coupling agent can be KH570, KH560 and KH550.
The present invention has following beneficial effect: it has prevented that shell from losing stratum corneum protection because processing polishing effectively, by acid, water, oxygen, the corrosion phenomenon from inside to outside that is harmful to chemistry etc. and cause, simultaneously, Parylene does vapour deposition under vacuum environment, no matter thereby shell is steep edge, crack, or trickle pin hole inwall can effectively permeate, and uniformity everywhere, and the shell after film has very strong acid and alkali-resistance, humidity, resistance to going mouldy, anticorrosive, high insulation high-low temperature resistant and good biocompatibility, thoroughly solve common pearl shell decorative sheet oxidizable, variable color, acid and alkali-resistance, the difficult problem that resistance to corrosion is poor, there is good market outlook and using value.
