The refrigeration plant of foregoing low noise, method of preparing methyl phenyl polysiloxane are as follows：
A. MTMS and diphenyldimethoxysilane are taken, adds in the glass reaction kettle with reflux, adds Enter MTMS and the acetone of 0.2 times of dimethoxydiphenylsilane gross mass；
B. it is 70-80 DEG C in temperature, rotating speed is that deionized water, deionized water are added into glass reaction kettle under 550-600r/min Amount be both MTMS and dimethoxydiphenylsilane in methoxyl group molal quantity summation；
C. after being added dropwise, continue to stir, flow back 4-5h, add organic solvent, it is 70%-75%, Ran Houjia to adjust its solid content Enter zinc Isoocatanoate, the addition of zinc Isoocatanoate is that zinc metal/hard resin mass ratio in zinc Isoocatanoate is 1.5%, continues to stir Afterwards, leuco base phenyl polysiloxane is arrived in cooling；
Wherein, the amount for adding MTMS and diphenyldimethoxysilane is MTMS and hexichol two Methoxy silane mol ratio 2：1-3：1.
The refrigeration plant of foregoing low noise, the preparation of the polyacrylate dispersion of short carbon chain containing perfluor：
（1）N- propyl group-N- ethoxy perfluoro hexyl sulfonamide is added in dry three-necked bottle, then adds the protochloride of brand-new Copper and triethylamine, the chloroform of half amount is added, make three miscible, the opaque mixture of system green；
（2）By second half remaining chloroform and acryloyl chloride miscible fluid, ice has then been slowly dropped under agitation In the three-neck flask of water-bath, remain that temperature is 0-5 DEG C in three-necked bottle in acryloyl chloride adition process, will after being added dropwise Oil bath is warming up to 75 DEG C, insulation reaction 6-7h；
（3）After reaction terminates, stop heating, be cooled to room temperature, system is in yellow, adds a certain amount of distilled water, is transferred to liquid separation Funnel, stratification, upper strata are greenish transparent liquid, and lower floor is pale yellowish oil liquid, retain lower floor's liquid, are used in combination Distill water washing for several times, transparent, the stopping washing until upper strata wash solution becomes colorless；Then two are washed with 5% sodium bicarbonate It is secondary, upper strata is separated after upper solution clarification, collects lower floor's oily organic matter；Again organic matter two is washed with saturated sodium-chloride It is secondary, with chloroform extraction, light yellow clear liquid is filtrated to get after extraction phase is dried with anhydrous magnesium sulfate, heats lower depressurize Solvent chloroform is distilled off, obtains light yellow oil, isolated colourless oily mater, i.e. N- propyl group is further purified Perfluoro hexyl sulfoamido ethyl propylene is Esterification；
（4）By deionized water, N- propyl group perfluoro hexyl sulfoamido ethyl propylenes are Esterification, octadecyl acrylate, acrylic acid -2- Hydroxyl ethyl ester, emulsifying agent are added in three-necked flask together, are warming up to 50 DEG C, pre-emulsification 30-40min, then in three-necked flask Nitrogen is passed through, adds excessively stream acid ammonium, is warming up to 70 DEG C, 4-5h is reacted, acetone soln of going out, that is, obtains white short chain containing perfluor and gather Acrylic acid ester emulsion.
The refrigeration plant of foregoing low noise, silicone-modified UV solidfication water polyurethane emulsion preparation methods are：
In the flask equipped with agitator, thermometer and condenser pipe, PTMG, polydimethylsiloxane, two are added Hydroxymethyl propionic acid and IPDI, under nitrogen protection, 90 DEG C are slowly warming up to, 0.5h are reacted, then by body The temperature of system drops to 40 DEG C, adds BDO and appropriate acetone, then slowly increases the temperature to 80 DEG C, reacts 1h, then After the temperature of system is dropped into 40 DEG C, pentaerythritol triacrylate and proper amount of acetone are added, finally drops to system temperature Room temperature, triethylamine is added, add water, emulsified in high shear agitation, mixing speed 800-1000r/min, finally decompression is steamed Solvent acetone is gone in distillation, and the solids content of system is 35-45%, the uniform and stable silane-modified UV curable water-bornes that pH value is 7-8 gather Urethane emulsion.
The beneficial effects of the invention are as follows：
The aminomethyl phenyl resin prepared in the present invention has good heat resistance, is suitable as the base-material of high-temperature resistant coating, in addition The methyl phenyl silicone resin resinoid containing methyl silica structure unit and phenyl silica structure unit simultaneously, due to phenyl Introduce, effectively raise it in thermoelasticity, the compatibility to materials such as the cohesiveness of various base materials and organic resin and pigment Etc. performance.
The pigment used in the present invention mainly plays a part of to cover and colouration；The filler of use mainly plays enhancing, assigns spy Different performance, change rheological property, reduce the effect of cost；The plasticizer used in the present invention can substantially reduce the glass of film Change temperature, and then strengthen the pliability of film, while can also reduce the MFT of emulsion coatings, improve coating workability Energy；During coating, there may be foam generation, therefore add proper quantity of defoaming agent and eliminate out foam.
Dispersant is with the addition of in the present invention, dispersant can increase the compatibility between base-material, can prevent that particle wadding is poly-, reduce and apply Expect viscosity, be firmly adsorbed on the surface of dispersed particle, and good space repulsion is provided, particle is filled under high velocity agitation After scattered, it will not reunite again because of Van der Waals force, adsorption layer will not also be shelled when being acted on by external force from particle surface From and cause the unstable of system, so as to optimize the physics of coating and chemical property.
The auxiliary material of the present invention be compound rare-earth, due to the metallic atomic radius of above rare earth element is big and rare earth with compared with High activity, it is easy to fill up the space of storeroom, meanwhile, rare earth element easily and the element compounds such as oxygen, sulphur to generate fusing point high Compound, the addition of compound rare-earth improve the dispersiveness and compatibility that prepare coating, make product mix equal to a certain extent The even anti-flammability for also improving coating.
Silicone-modified UV solidfication water polyurethane emulsions, compared with unmodified anticorrosive paint, silicon are employed in the present invention Siloxane modified UV solidified aqueous coatings have good water resistance and solvent resistance, excellent ratio surface property, retain simultaneously Excellent feel.
Pass through technical scheme, by increasing capacitance it is possible to increase the service life and soundproof effect of coating, the coating will not occur The problems such as foaming, cracking, whiting and delamination, the coating also has very strong anticorrosive and resistance to saltfog energy, can firmly adsorb Metal surface, so as to have good sound insulation value；The coating application is convenient, easily operated, the advantages that short construction period.
