Description
Technical field
The present invention relates to chemical field, relate in particular to a kind of manufacture method of multifunctional heat insulating pipe.
Background technique
Thermal insulation pipe is the abbreviation of insulated piping, thermal insulation pipe is for the conveying of liquid, gas and other media, adiabatic heat-insulation engineering at oil, chemical industry, space flight, military affairs, central heat supply, central air-conditioner, municipal administration etc. pipeline, yet owing to using local difference, its performance that will possess is also different, such as properties such as radiation resistance, water resistence, heat resistance, winter hardiness, stain resistance, electrical insulating property and elasticity, yet thermal insulation pipe of today fails to possess these performances simultaneously, during use, also need to select different thermal insulation pipes, wasted money.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of manufacture method of multifunctional heat insulating pipe.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of manufacture method of multifunctional heat insulating pipe, described multifunctional heat insulating pipe is by thermal insulation pipe body and be coated in the outer field coating of described thermal insulation pipe and form.
In a preferred embodiment of the present invention, the proportioning of described coating is by weight percentage: ethyl orthosilicate 48%, ethanol 14%, water 6%, hydrochloric acid 0.5%, silane coupler 0.2%, polyurethane 14%, color stuffing 14%, cellulose family auxiliary agent 3.3%.
In a preferred embodiment of the present invention, concrete steps comprise:
(1) prepare base fluid: ethyl orthosilicate and ethanol are added to fully stirring in three mouthfuls of beakers, and add water and hydrochloric acid, make it produce hydrolysis reaction, after completing, hydrolysis reaction is warming up to 100 ℃ of boilings, distill out the little molecular product of ethanol, by the ethanol amount of steaming, control the product extent of reaction, add silane coupler to make ethyl polysilicate base fluid;
(2) preparation of coating: after ethyl polysilicate base fluid and polyurethane are uniformly mixed by proportioning, add a certain amount of color stuffing and auxiliary agent to make coating;
(3) by the described spray painting of making on described thermal insulation pipe body, use hot air to be dried.
The invention has the beneficial effects as follows: the manufacture method of a kind of multifunctional heat insulating pipe of the present invention, the thermal insulation pipe of the party's legal system manufacture has good radiation resistance, can not get wet, and operating temperature still under the condition of extremely hot and severe cold, can not stain, also there is fine electrical insulating property and elasticity.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
The embodiment of the present invention comprises: a kind of manufacture method of multifunctional heat insulating pipe, described multifunctional heat insulating pipe is by thermal insulation pipe body and be coated in the outer field coating of described thermal insulation pipe and form, and described coating has the properties such as excellent radiation resistance, water resistence, heat resistance, winter hardiness, stain resistance, electrical insulating property and elasticity.
The proportioning of described coating is by weight percentage: ethyl orthosilicate 48%, ethanol 14%, water 6%, hydrochloric acid 0.5%, silane coupler 0.2%, polyurethane 14%, color stuffing 14%, cellulose family auxiliary agent 3.3%.
Concrete steps comprise:
(1) prepare base fluid: ethyl orthosilicate and ethanol are added to fully stirring in three mouthfuls of beakers, and add water and hydrochloric acid, make it produce hydrolysis reaction, after completing, hydrolysis reaction is warming up to 100 ℃ of boilings, distill out the little molecular product of ethanol, by the ethanol amount of steaming, control the product extent of reaction, add silane coupler to make ethyl polysilicate base fluid, in silane coupled agent molecule, contain two kinds of different active genes---amino and oxygen base, be used for coupling organic polymer and mineral filler, strengthen its cohesiveencess, improve the machinery of product, electric, water-fast, the performance such as anti-aging.
(2) preparation of coating: after ethyl polysilicate base fluid and polyurethane are uniformly mixed by 5:1 proportioning, add a certain amount of color stuffing and auxiliary agent to make coating.
When described ethyl polysilicate base fluid and described polyurethane are pressed 5:1 proportioning, the combination property of coating is best, increase along with polyurethane content, its filming performance, water resistence and acid resistance are improved by poor, by good variation, the hardness after blend also declines to some extent, also can judge thus again, filming performance is better, coating surface is finer and close, and the erosion meeting of water and acid seal paing film significantly declines, thereby has improved water-fast, the acid resistance of paint film.
Color stuffing described in the present embodiment is titanium dioxide, because color stuffing is hydroaropic substance, if the hydrophilic group in coating base fluid is very little, and coating cracking, peeling dry linting, and also coating can solidify very soon; Color stuffing adds very few, does not reach the object of covering, affects its outward appearance.When color stuffing adds when too much, although hardness of paint film promotes to some extent, filming performance variation, considers, and color stuffing addition is comparatively suitable 20% time.If the viscosity of coating is too low or color stuffing adds too much, coating there will be stratification, can not be long placed in, if viscosity is too low, should add auxiliary agent, and described auxiliary agent is the viscosity that cellulose family auxiliary agent contributes to improve coating.
(3) by the described spray painting of making on described thermal insulation pipe body, use hot air to be dried, heated air drying is to adopt convective principles, the hot air that the temperature of take is 40～60 ℃ is heat-loading body, coating by thermal energy transfer to workpiece surface, the heating and drying method of film-forming after coating absorption energy.Conventional electricity or steam, as thermal source, first make air heating, and heat, by passing to coating surface to streamed by hot air, makes coating obtain fast drying.Adopting hot air drying technique, can obviously accelerate coating drying rate, and have adaptable feature, is widely used a kind of dried forms.
Compared with prior art, the manufacture method of a kind of multifunctional heat insulating pipe of the present invention, the thermal insulation pipe of the party's legal system manufacture has good radiation resistance, can not get wet, operating temperature still under the condition of extremely hot and severe cold, can not stain, and also has fine electrical insulating property and elasticity.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention to do, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
